Mobile broadband demand continues to rise exponentially around the world The demand forthis service far outstrips the currently available spectrum for delivering this service

As depicted below the current operator spectrum pool will be unable to cope with thegrowing demand of mobile broadband unless the usage of existing spectrum is optimized or

new spectrum is obtained

Acquisition of new spectrum is dependent on regulatory policy and usually comes with a highprice tag This makes refarming of existing spectrum for use with more efficient technologiesa more viable option in the near term for meeting the growing demand

In Telkomsel besides with existing 900MHz 1800Mz and 2100Mz there is a plan to acquirenew license in 700MHz 850MHz 2300MHz and 2600MHz subjected to market environmentand regulatory approval

2 Refarming Trends

Refarming is largely driven by the need to move to technologies which provide far moreefficiency in the existing spectrum over older generation technologies

Moving from existing 2G spectrum to WCDMA or LTE provides gt100 efficiency

3GPP and most of the global operators have identified use cases for specific bands whichhave also lead to the device ecosystem to be developed in step with the market need

Use of lower frequencies for radio access coverage building is beneficial due to better signalpropagation This leads to remarkably less base station sites and thereby to significantlyreduced OPEX and CAPEX for an operator

Today the 9001800MHz spectrum is very often already used by GSM This makes theWCDMALTE deployment to these bands challenging As operators naturally want to servealso their existing GSM subscribers the available spectrum needs to be divided betweenGSM and WCDMALTE networks The challenge is how to successfully accommodateWCDMALTE into frequency band that is currently used by GSM and at the same time keepthe GSM capacity and quality unchanged

Terminal availability and penetration are important for refarming feasibility First device for

U900L1800 are already available and more are coming According to GSA report (Sept2012) a total of 978 UMTS900 and 98 LTE1800 user devices across all categories(Smartphone dongles router and tablets) were confirmed as having been officiallyannounced by manufacturers including carrier and frequency variants From these devices96 of them can support both U900 and L1800 simultaneously

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

Mobile broadband demand continues to rise exponentially around the world The demand forthis service far outstrips the currently available spectrum for delivering this service

As depicted below the current operator spectrum pool will be unable to cope with thegrowing demand of mobile broadband unless the usage of existing spectrum is optimized or

new spectrum is obtained

Acquisition of new spectrum is dependent on regulatory policy and usually comes with a highprice tag This makes refarming of existing spectrum for use with more efficient technologiesa more viable option in the near term for meeting the growing demand

In Telkomsel besides with existing 900MHz 1800Mz and 2100Mz there is a plan to acquirenew license in 700MHz 850MHz 2300MHz and 2600MHz subjected to market environmentand regulatory approval

2 Refarming Trends

Refarming is largely driven by the need to move to technologies which provide far moreefficiency in the existing spectrum over older generation technologies

Moving from existing 2G spectrum to WCDMA or LTE provides gt100 efficiency

3GPP and most of the global operators have identified use cases for specific bands whichhave also lead to the device ecosystem to be developed in step with the market need

Use of lower frequencies for radio access coverage building is beneficial due to better signalpropagation This leads to remarkably less base station sites and thereby to significantlyreduced OPEX and CAPEX for an operator

Today the 9001800MHz spectrum is very often already used by GSM This makes theWCDMALTE deployment to these bands challenging As operators naturally want to servealso their existing GSM subscribers the available spectrum needs to be divided betweenGSM and WCDMALTE networks The challenge is how to successfully accommodateWCDMALTE into frequency band that is currently used by GSM and at the same time keepthe GSM capacity and quality unchanged

Terminal availability and penetration are important for refarming feasibility First device for

U900L1800 are already available and more are coming According to GSA report (Sept2012) a total of 978 UMTS900 and 98 LTE1800 user devices across all categories(Smartphone dongles router and tablets) were confirmed as having been officiallyannounced by manufacturers including carrier and frequency variants From these devices96 of them can support both U900 and L1800 simultaneously

d Base Station evolution

After refarming the traditional cabinet type base stations will be replaced with smallsize modular Flexi Multiradio10 base station from Nokia Siemens Networks ExistingDual-band antenna and feeders will be reused for GSM9001800 For L1800 a new2-port antenna will be used Below diagram show the BTS site after U900 and L1800refarming

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

Acquisition of new spectrum is dependent on regulatory policy and usually comes with a highprice tag This makes refarming of existing spectrum for use with more efficient technologiesa more viable option in the near term for meeting the growing demand

In Telkomsel besides with existing 900MHz 1800Mz and 2100Mz there is a plan to acquirenew license in 700MHz 850MHz 2300MHz and 2600MHz subjected to market environmentand regulatory approval

2 Refarming Trends

Refarming is largely driven by the need to move to technologies which provide far moreefficiency in the existing spectrum over older generation technologies

Moving from existing 2G spectrum to WCDMA or LTE provides gt100 efficiency

3GPP and most of the global operators have identified use cases for specific bands whichhave also lead to the device ecosystem to be developed in step with the market need

Use of lower frequencies for radio access coverage building is beneficial due to better signalpropagation This leads to remarkably less base station sites and thereby to significantlyreduced OPEX and CAPEX for an operator

Today the 9001800MHz spectrum is very often already used by GSM This makes theWCDMALTE deployment to these bands challenging As operators naturally want to servealso their existing GSM subscribers the available spectrum needs to be divided betweenGSM and WCDMALTE networks The challenge is how to successfully accommodateWCDMALTE into frequency band that is currently used by GSM and at the same time keepthe GSM capacity and quality unchanged

Terminal availability and penetration are important for refarming feasibility First device for

U900L1800 are already available and more are coming According to GSA report (Sept2012) a total of 978 UMTS900 and 98 LTE1800 user devices across all categories(Smartphone dongles router and tablets) were confirmed as having been officiallyannounced by manufacturers including carrier and frequency variants From these devices96 of them can support both U900 and L1800 simultaneously

After refarming the traditional cabinet type base stations will be replaced with smallsize modular Flexi Multiradio10 base station from Nokia Siemens Networks ExistingDual-band antenna and feeders will be reused for GSM9001800 For L1800 a new2-port antenna will be used Below diagram show the BTS site after U900 and L1800refarming

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

3GPP and most of the global operators have identified use cases for specific bands whichhave also lead to the device ecosystem to be developed in step with the market need

Use of lower frequencies for radio access coverage building is beneficial due to better signalpropagation This leads to remarkably less base station sites and thereby to significantlyreduced OPEX and CAPEX for an operator

Today the 9001800MHz spectrum is very often already used by GSM This makes theWCDMALTE deployment to these bands challenging As operators naturally want to servealso their existing GSM subscribers the available spectrum needs to be divided betweenGSM and WCDMALTE networks The challenge is how to successfully accommodateWCDMALTE into frequency band that is currently used by GSM and at the same time keepthe GSM capacity and quality unchanged

Terminal availability and penetration are important for refarming feasibility First device for

U900L1800 are already available and more are coming According to GSA report (Sept2012) a total of 978 UMTS900 and 98 LTE1800 user devices across all categories(Smartphone dongles router and tablets) were confirmed as having been officiallyannounced by manufacturers including carrier and frequency variants From these devices96 of them can support both U900 and L1800 simultaneously

After refarming the traditional cabinet type base stations will be replaced with smallsize modular Flexi Multiradio10 base station from Nokia Siemens Networks ExistingDual-band antenna and feeders will be reused for GSM9001800 For L1800 a new2-port antenna will be used Below diagram show the BTS site after U900 and L1800refarming

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

d Base Station evolution

After refarming the traditional cabinet type base stations will be replaced with smallsize modular Flexi Multiradio10 base station from Nokia Siemens Networks ExistingDual-band antenna and feeders will be reused for GSM9001800 For L1800 a new2-port antenna will be used Below diagram show the BTS site after U900 and L1800refarming

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

d Base Station evolution

After refarming the traditional cabinet type base stations will be replaced with smallsize modular Flexi Multiradio10 base station from Nokia Siemens Networks ExistingDual-band antenna and feeders will be reused for GSM9001800 For L1800 a new2-port antenna will be used Below diagram show the BTS site after U900 and L1800refarming

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

d Base Station evolution

After refarming the traditional cabinet type base stations will be replaced with smallsize modular Flexi Multiradio10 base station from Nokia Siemens Networks ExistingDual-band antenna and feeders will be reused for GSM9001800 For L1800 a new2-port antenna will be used Below diagram show the BTS site after U900 and L1800refarming

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

d Base Station evolution

After refarming the traditional cabinet type base stations will be replaced with smallsize modular Flexi Multiradio10 base station from Nokia Siemens Networks ExistingDual-band antenna and feeders will be reused for GSM9001800 For L1800 a new2-port antenna will be used Below diagram show the BTS site after U900 and L1800refarming

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

d Base Station evolution

After refarming the traditional cabinet type base stations will be replaced with smallsize modular Flexi Multiradio10 base station from Nokia Siemens Networks ExistingDual-band antenna and feeders will be reused for GSM9001800 For L1800 a new2-port antenna will be used Below diagram show the BTS site after U900 and L1800refarming

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

d Base Station evolution

After refarming the traditional cabinet type base stations will be replaced with smallsize modular Flexi Multiradio10 base station from Nokia Siemens Networks ExistingDual-band antenna and feeders will be reused for GSM9001800 For L1800 a new2-port antenna will be used Below diagram show the BTS site after U900 and L1800refarming

e Mobility between layers and layering strategy

After the refarming Telkomsel will have to maintain a multi-layer network with differenttechnologies (GSMUMTSLTE) and frequencies (90018002100) In such heterogeneousnetworks (HetNets) end users are moving and expecting constant network availability and

full service continuity Besides smooth transitions between different technologies when

UEs are being in idle mode or coverage or service limited should be available In the case ofcongestion there should be a mechanism to offload between layers to ensure the network torun much more efficiently (traffic steering and load balancing)

In Nokia Siemens networks all the necessary mobility between layers will be offered toTelkomsel Below figure shows the summary of the available mobility in Telkomsel HetNets

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

The objective of the layering strategy is to ensure seamless interworking between allfrequency bands and layers that maintains end user quality of experience The proposedstrategy

bull To keep U900 capable UEs camping on U900 most of the time

bull Voice call preferred on U900 layer dongle preferred on U2100 layer Fast moving UE onU900 layer

bull To use G900 voice calls only in case absolutely needed (ie neither G1800 U900 nor U2100coverage available)

bull To actively push UEs from U900 to U2100 when U2100 coverage is good enough to offloadU900 traffic to U2100 (since there are more carriers in U2100) Load Balancing within U900and U2100 bands possible

bull To keep U2100 Carrier 1 for R99ampHSPA UMTS carrier 2 and 3 preferred HSPA U2100carrier 4 for small cell eg Femto

bull To keep L1800 capable UEs camping on L1800 most of the time CSFB to UMTSGSM whenout of coverage Another option is to use VoIP with IMS then CSFB is not needed

f Interference mitigation

For the 900 limited band like Telkomsel the same frequencies have to be re-used There isa possible co-channel interference when these layers are using the same frequency withinthe same geographical area If not controlled it may decrease the network performancesignificantly

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned

g Fragmented 1800MHz bands rearrangement proposal

As stated in Chapter 4 ndash Technical Specifications and Requirement Clause 463 Telkomselwould like to have a proposal of rearrangement of their currently fragmented bands in1800MHz Nokia Siemens Networks is proposing below spectrum rearrangement for

1800MHz as shown in below figure After the rearrangement Telkomsel 1800MHz should tryto get the spectrum for one end of 1800Mz band Nokia Siemens Networks proposes to get18575MHz to 1880MHz (225MHz contiguous band) The center frequency for LTE1800should also be the center of the band (186875MHz) The advantage of getting the whole1800MHz band on one side is to reduce the possible interference since only one end isdirectly interfering the other operator 1800MHz frequency band

The effort and cost involved in such rearrangement exercise arebull Possible fee from regulator for rearrangement exercise

bull Possible resistance from existing operator to change their existing allocation as there will beimpact

bull Neighbors re-planning for all existing GSM1800 site

bull All the existing GSM1800 BTS new center frequency to be retuned
