Event

New


CBS Event triggered broadcast

Description

Cell Broadcast Service (CBS) enables broadcast of information,

E.g. traffic news or warnings, to devices in a pre-defined area.

Broadcasting provides an efficient way to reach a large population of devices with a message

Benefit

Event triggered broadcast provides a way to reduce impact of CBS on the device battery lifetime to virtually zero

Allows

to reduce time to deliver an emergency messages to below 8 sec allowing one repeated transmission


CBS Event triggered broadcast Sending a message

By reading system information the UE finds out how and when to decode the CBS messages

With event triggered broadcast the following happens when a message is sent

The system information broadcast (SIB) is updated signaling that

the CTCH is active

The devices are notified that the SIB is updated

The message is repeated on the CTCH a configurable number of times

When the message is sent, the CTCH is turned off and the SIB returns to its original state

Performance of 4-way diversity

The number of receiver antennas is of fundamental importance for the capacity of a CDMA radio system

Theoretically the capacity scales with the number of antennas

This is since lower receiver power is needed to achieve a certain signal to interference ratio

With Interference Suppression (FAJ 121 1714) gains may be even larger

Since lower received power is needed, the coverage is also enhanced

RIM Support for System Information transfer to LTEFAJ 121 2179 Optional

New


RIM Support for System Information transfer to LTE

Description

With RIM then the LTE RBS subscribes to system information from all WCDMA cells, i.e. system broadcast info is sent from the WCDMA RNC to all LTE RBSs that subscribes to this info

The LTE network includes the WCDMA system broadcast info in the release massage to the UE

Benefit

The UE needs only to read a small part of the system broadcast before doing access to WCDMA

Decreases the extra call set up delay up to 0.5 to 0.7s compared

to W11

CS Fallback from LTE - DMCR


Enhanced


CS Fallback from LTEDescription

Makes it possible for handsets that is camping in LTE to make and receive Voice calls

New information is broadcasted in system info that makes it possible for the UE to access the system faster

Using Deferred Measurement Control Reading

Benefits

Reduces the call set up time with 1 second for CS Fallback from LTE

GPEH Capacity Increase - Reduced ROP periodicity


New


GPEH Capacity Increase - Reduced ROP periodicity

Description

The new GPEH Capacity Increase feature is based on and fully compatible with the existing GPEH feature, but provides support for far higher level of event intensity and recording capability as well as reduced ROP periodicity to 1 minute ROP periods, instead of 15 minutes ROP periods

Benefits

More efficient and much faster network analysis, satisfying the need to both existing, as well as creating a solid ground for future advanced event based applications, like:

Boosted GPEH capacity satisfies future data demand

Frequent data provisioning with smaller files every minute

Flexible counter resolution possible for EBS based counters

System Improvements in W12 Release

FAJ 121 1651 Basic New/enhanced


Combine Add/Remove cells in one ASU procedure

Reducing air interface signaling by combining two measurement reports into one active set update.

Combining event 1a and event 1b into one replace action.

Benefit

Reducing probability to delay handover execution and thereby risk of dropping the call

Add Remove

Improved call drop rate


Best Useful candidate event 1a and Event 1c Reports evaluation

Description

If the best cell is unknown in an e1a or e1c measurement report and the report contains multiple cells fulfilling the event criteria

The unknown cell is discarded and evaluation of the remaining cells fulfilling the event criteria continue until a cell that is known is found

Benefit

Reduced risk of dropping the call in networks with missing neighbor cell relations

Event 1A MR

Cell A (unknown)

Cell B

Cell C


Soft congestion enhancements

Description

Incoming high priority request will also target

A-DCH, i.e. down switch of a lower priority HSDPA user to FACH (Also in W11B CP1)

EUL min resource, i.e. down switch a lower priority EUL user to FACH (Also in W11B)

Both these are operator controllable (on/off)

Benefits

Improved accessibility for higher priority services


Network Handling

RNC Supervision

Alarm when the percentage of disabled or locked devices in an SP-

pool exceeds a threshold

Delayed activation of Capacity Control RNC

Grace period when traffic exceeds licensed capacity

Upgrade robustness

More pre-checks before a SW upgrade, reducing the risk of upgrade failures, and giving information on needed actions to ensure a successful upgrade

Possibility to run Verify Upgrade

earlier, giving earlier information on needed actions

Alarm filtering

Improved fault management quality -

Avoid massive alarm flow towards OSS during RBS upgrade


L1 and l3 Admin

This system improvement gives the possibility to control the following parameters

n313, i.e. the 3GPP parameter that sets the number of frames for the

UE to be out of synch

n315, i.e. the 3GPP parameter that sets the number of frames for the

UE to be in synch

t313, i.e. the 3GPP parameter that sets the waiting time for the UE to determine "RL failure"

The L3 supervision timer for the RRC connection setup procedure

The L3 supervision timer for synchronized DCH-DCH reconfigurations, e.g. RAB establishment, RAB release, Channel switching, HS serving cell change

The L3 supervision timer for non synchronized DCH-DCH reconfigurations, e.g. Active set update, RB reconfiguration

The L3 supervision timer for reconfigurations to/from Cell_FACH


Volume

counters

per Ip

interface

Description

Counter for number of octets (Bytes) sent from an IP interface. Counter for number of octets (Bytes) received by an IP interface.

Benefit

Better observability

of the individual logical interfaces (Iur, IuCS

and IuPS) even if they share a physical port. This allows measuring the

bandwidth received and transmitted from each logical interface.


RNC overload robustness

Description

Code optimization to reduce Module MP load at cell congestion

Avoid

non-linear

MP load

increase

at high MP load

and soft congestion

Benefit

Increased accessibility by reducing processor load


Increased

number

of Iur

links

Description

Number of Iur

links one RNC can configure is today limited to 64

With this feature this limit will be increased to 128 on RNC 3820 and EvoC. RNC 3810 is limited by HW resources. An RNC 3820 or EvoC

can still interface with an RNC 3810.

Benefit

Reduced risk of dropped call for users speaking on the phone when traveling

Simpler configuration of Iur

for markets with large number of RNCs.

Other w12b impacts

W12B introduces locks for HWAC (Hardware Activation Codes) for RBS 6000 only.

Essential to perform a network validation to ensure that installed HWAC capacity is the same or higher than installed SW capacity (to avoid traffic degradation)

W12B is not yet supported on EvoC

8200/RNC.

Today W12B is only available for RNC3810 and RNC3820

W12B will be supported on EvoC

8200/RNC is Dec-2012 in a separate SW release.
