Fig. 1.2-4 Structure of SPCU
SPCU consists of PUC and the protocol processing board FRP or BRP (both of which
adopt GDPP as the hardware).
PCU processes 3 kinds of protocols, namely: FR, BSSGP, and RLC/MAC protocols.
BSSGP and RLC/MAC protocols are processed by BRP, and the FR protocol is
processed by FRP.
PUC manages FRP and BRP, provides the communication channel for BRP and RMM,
completes the circuit switching between the service channel of the switching network
and BRP, and the circuit switching between the Gb channel of GIPP and FRP. PUC is
connected with FRP and BRP through one 8M HW single-polarity cable. It is
connected with the T-net and the GIPP of GIU through one 8M HW differential cable.
1.2.4 Backplane andInterface
The backplane of the BPCU shelf is the BPCU board, the rear view of which is

In case of expanding the GPRS rack, it is necessary to determine the BGA
type according to the number of racks. If the central rack is configured, it is
not necessary to configure the GPRS rack.
Use BGA01 if the number of racks is 1; use BGA02 if the number of racks is
2; use BGA03 if the number of racks is 3; use BGA04 if the number of racks
is 4; and use BGA05 if the number of racks is 5. As for the cables mentioned
above, only 1 cable is required if there is only 1 BSC.
Use A+ cable if the number of racks is higher than 5. Use BGA+01 if thenumber of racks is 6; and use BGA+02 if the number of racks is 7.

Chapter 2 Data Preparation
2.1 DATA REQUIRED
For SGSN, the five items of data should be provided: NSEI, NSVCI, DLCI
(Data Link Carrier Identity), BRCH and RAC.
NSEI: Network Service Entity Identifier
NSVCI: Network Service Virtual Connection Identifier, which identifies the
network service virtual connection from BSS to SGSN
BRCH: Bear Channel, timeslot number for use of trunk circuit
DLCI: Data Link Connect Identity, which is a concept related to frame relayRAC: Routing Area Code Like the GSM which uses location area to manage a
group of cells, the GPRS further itemizes the management, and divides one
location area into several routing areas, identified with RAI
(MCC+MNC+LAC+RAC).

Chapter 3 Data Configuration
3.1 Back Up the Foreground and Background Data
3.1.1 Use the tools/dbbak/cmexp to export the DUMP data of the
background
3.1.2 Use the OMCFTP tool to retrieve the ZDB data of the modules at the
foreground
3.2 Modify the Configuration File of Server and Restart theOMCR
Make sure that Environment = GSM in $OMCHOME/conf/syscfg.ini is
changed to Environment = GPRS, so as to give rise to the GPRS
configuration options.
Restart the OMCR server.
3.3 Perform Physical Configuration in the IntegratedConfiguration Environment
3.3.1 Add rack
Perform the operation of adding rack through Physical view in the
integrated configuration environment. Add a new rack in Physical view (or
configure it in the vacant shelf of the original rack), and then add the two
layers of shelves: ZXG10_GIU and ZXG10_SPCU.

3.3.2 Add board
When adding the three types of boards: GIPP, PUC and TIC, pay attention to
the following aspects:
Note down the allocated HW number of the GIPP and PUC boards for ease of
physical connection

22/40
3.3.3 For TIC, the BRCH should be configured
Add TS according to the BRCH data provided by SGSN. For example, in the
following illustration, SGSN allocates the TS1-8, and uses default values for
other items.
Note: The FRPNO connected with the BRCH of the same PUC may vary.
Therefore, when configuring the second PCM, it is necessary to select 2 for
FRPNO.

3.3.4 Configure NSVC
In Physical view, right click on BSC. In the menus that appear, select
Configure NSVC and start the configuration.
NSEI, NSVCI and DLCI are provided by SGSN.
Burst package size can be set as 640KB*number of timeslots. Here the BRCH has 8
timeslots, so it can be set as 640*8=5120KB.
For other parameters, the default values apply.

3.4 Perform Radio Configuration in the IntegratedConfiguration Environment
3.4.1 Configure the GPRS cell to make it support GPRS or not
In the Edit radio information of cell window, select Support GPRS, and
the GPRS cell options window will appear.
3.4.2 Configure relevant data in GPRS cell options
In the GPRS cell options window, input the following data:
NSE ID:
Select the service entity of the network
BVC ID:
ID of the BSSGP Virtual Connection (BVC). Under the same Network Service
Entity (NSE), each GPRS cell can be identified uniquely by a BVCI.
Generally, a BVCI = SITEID + CELLID. (For example, set 11 as the BVCI for the
first cell 1 of site 1)
Routing area code:
Provided by SGSN
Routing color code:
Set according to the network planning
7/28/2019 ZXG10-BSS-GPRS Operation and Commissioning Procedure
27/40
BRP group:
Select the corresponding BRP group, whose value range is 1~6.
The correspondence relationship between the BRP group and the BRP
board is:
The BRP board is designed as N+M backup. If seven BRP boards are
configured as a full capacity, it is 6+1 backup. Therefore, the BRP groups are
in a one-to-one relationship with the BRP boards.
However, the BRP board decides the logical serial number according to the
sequence of startup. The first started BRP board is the first BRP group.
Therefore, no necessary relationship exists between the BRP group and the
actual slot.
You can use the dynamic data management to search the BRP board
corresponding to the current BRP group, or use the data probe to search the
R_BRP table of the central module and then obtain the BRP board from the
BRPgroup field.
Each BRP group supports a maximum of 40 GPRS cells or 40 PS
channels (sum of dynamic channels and static channels). Generally, 40 PS
channels are preferable. Therefore, before configuring the data, it is necessary
to allocate the BRP groups as required in advance to avoid too many channels
configured on a BRP group.
LSA ID: Remains unchanged
3.4.3 Configure static and dynamic channels
1. During the radio resources configuration, adjust configurations of the
7/28/2019 ZXG10-BSS-GPRS Operation and Commissioning Procedure
28/40
PDTCH channel in each cell to ensure the numbers of both the dynamic
and static PDTCH channels configured on each BRP board are not more
than 40.
2. For the offices with large GPRS flow (esp. overseas offices), the
numbers of both the dynamic and static PDTCH channels configured on
each BRP board should not be more than 30.
3. Packet channels are configured in the BCCH carrier frequency.
4. Do not configure dynamic channels for sites in a city zone.
5. A dynamic channel should be configured behind a static channel, that is,
the time slot of a dynamic channel should be larger than that of a static
channel.
6. TSC of the PDTCH channels on the same TRX should be identical.
7. When the frequency hopping is used, the packet time slots on the same
TRX should have the same frequency parameters (MA, MAIO and HSN)
and the same training sequence codes (TSC).
8. If you choose to configure a cell to support PS, you must configure at
least one PS channel.
9. Configure one dynamic channel for a cell with one carrier frequency.
10. Configure one static channel for a cell with two carrier frequencies.
11. Configure two static channels for a cell with three carrier frequencies.
12. Configure three static channels for a site with more than three carrier
frequencies.
13. Configure four or more static channels for key sites.

3.5 Modifying Relevant Timers in Radio ResourceManagement
3.5.1 Modifying the timers of BSC
7/28/2019 ZXG10-BSS-GPRS Operation and Commissioning Procedure
30/40
T3193: The default value of this parameter is 51. The value of this parameter should be
greater than that of the timer T3192.
7/28/2019 ZXG10-BSS-GPRS Operation and Commissioning Procedure
31/40
CellFcThs: The threshold of BVC flow control.
It is the threshold of triggering the BVC flow control process. The BVC flow control
is performed between the SGSN and the BSS, namely, on the Gb interface, and is
performed only on the downlink. Specifically, the BSS provides the flow control
parameters and the SGSN implements them. The BVC flow control aims to prevent
discarding some LLC data due to timeout caused by too busy packet channels (too many
buffered LLC frames) in a BVC on the BSS, or discarding the new downlink LLC datadue to limited memory resources (overflow of LLC frame buffer). The BSS GP process
at the BSS side makes statistics of the current overflow ratio of the BVC periodically
(including short statistics and long statistics). In case of overflow of long statistic timer,
the BVC flow control process will be originated unconditionally. When the difference
between two overflow ratios is greater than CellFcThs, the triggering of the process is
subject to confirmation of the SGSN. In case of overflow of short statistic timer, and the
difference between two overflow ratios is greater than CellFcThs, the BVC flow
control process will be originated. In this case, the triggering of the process is also
subject to confirmation of the SGSN. The default value of this parameter is 80.
CellFcPer: Flow control period of BVC:
It is the BVC overflow ratio statistic period, namely, BVC long statistic period in the
BVC flow control process. In order to provide reference for the BVC flow control at
the SGSN side, the BSSGP process at the BSS side makes statistics of the current
overflow ratio of the BVC periodically. In case of overflow of long statistic timer, the
BVC flow control process will be originated unconditionally. When the difference
between two overflow ratios is greater than CellFcThs, the triggering of the process is
subject to confirmation of the SGSN. In case of overflow of short statistic timer, and the
difference between two overflow ratios is greater than CellFcThs, the BVC flow
control process will be originated. In this case, the triggering of the process is also
7/28/2019 ZXG10-BSS-GPRS Operation and Commissioning Procedure
32/40
subject to confirmation of the SGSN. In our system, BVC short statistic period = BVC
long statistic period / 3. The default value of this parameter is 3000. At Bijie, this
parameter is set to 30000.
MsFcThs: MS flow control threshold.
It is the threshold of triggering the MS flow control process. The MS flow control is
performed between the SGSN and the BSS, namely, on the Gb interface, and is
performed only on the downlink. Specifically, the BSS provides the flow control
parameters and the SGSN implements them. The MS flow control aims to prevent
discarding some LLC data due to timeout caused by too busy packet channels (too many
buffered LLC frames) in an MS in the BSS, or discarding the new downlink LLC data
due to limited memory resources (overflow of LLC frame buffer). The BSS GP process
at the BSS side makes statistics of the current overflow ratio of the MS periodically
(including short statistics and long statistics). In case of overflow of long statistic timer,
the MS flow control process will be originated unconditionally. When the difference
between two overflow ratios is greater than MsFcThs, the triggering of the process is
subject to confirmation of the SGSN. In case of overflow of short statistic timer, and the
difference between two overflow ratios is greater than MsFcThs, the MS flow control
process will be originated. In this case, the triggering of the process is also subject to
confirmation of the SGSN. The default value of this parameter is 80.
MsFcPer: Flow control period of MS.
It is the MS overflow ratio statistic period, namely, MS long statistic period in the
MS flow control process. In order to provide reference for the flow control at the
SGSN side, the BSSGP process at the BSS side makes statistics of the current overflow
ratio of each MS periodically. In case of overflow of long statistic timer, the MS flow
control process will be originated unconditionally. When the difference between two
overflow ratios is greater than MsFcThs, the triggering of the process is subject to
confirmation of the SGSN. In case of overflow of short statistic timer, and the difference
between two overflow ratios is greater than MsFcThs, the MS flow control process
will be originated. In this case, the triggering of the process is also subject to
confirmation of the SGSN. In our system, MS short statistic period = MS long statistic
period / 3. The default value of this parameter is 3000. At Bijie, this parameter is set to
30000.
MS encoding mode:
The GPRS data block can adopt different encoding modes in CS-1 ~ CS-4. The
corresponding data rates are 9.05kb/s, 13.4kb/s, 15.6kb/s and 21.4kb/s respectively. The
encoding mode at a lower level has a higher error correction capability and a lower data
throughput. When the radio transmission quality of the network is good, it means a low
probability of retransmitting error radio blocks. In this case, the encoding mode with a
larger data amount (namely, channel encoding mode at a higher level) can be used. The
default mode is CS-1. At Bijie, the encoding mode is CS-2.
N3101 (maximum permitted number of consecutive lost uplink data blocks):
7/28/2019 ZXG10-BSS-GPRS Operation and Commissioning Procedure
33/40
The parameter for use at the RLC/MAC layer on the BRP. During the packet uplink
transmission process, the BSS will specify a USF (corresponding to an uplink TBF) for
each uplink block. For a USF, if the network receives data correctly on the specified
uplink data, it will clear the counter N3101 for this NBF. If the count of consecutive
losses on the specified uplink block is more than N3101 (N3101max), the timer T3169will be started. Upon expiry of the timer T3169, the network can reuse the TFI and USF
resources. The default value of this parameter is 10. At Bijie, this parameter is set to 9.
N3101 (count of packet uplink acknowledged / unacknowledged
reattempts):
The parameter for use at the RLC/MAC layer on the BRP. During the packet uplink
transmission process, if the network detects that the uplink TBF is completed (CV=0,
and V(Q)=V(R)), and all RLC data blocks have been received, the network will send a
packet uplink acknowledged / unacknowledged message to set the last
acknowledgement identity to 1. The identity header of the RLC/MAC control block
includes a legal RRBP domain. Then, the network will clear the counter N3103. If the
MS receives the packet uplink acknowledged / unacknowledged message whose FAI
is 1 as sent from the network side, the MS should send the packet control
acknowledgement message on the corresponding block specified by the RRBP, and
release the TBF. If the network has not received the packet control acknowledgement
message in the radio block specified by the RRBP field, the network should increase the
value of the counter N3103, and retransmit the packet uplink acknowledged /
unacknowledged message. If the counter N3103 goes beyond the N3103 (N3103max),
the network should start the timer T3169. Upon expiry of the timer T3169, the networkcan reuse the TFI and USF resources. The default value of this parameter is 10. At Bijie,
this parameter is set to 8.
N3105 (maximum permitted number of consecutive lost uplink RLC/MAC
control messages):
The parameter for use at the RLC/MAC layer on the BRP. During the packet downlink
transmission process, the BSS will set the RRBP field on the downlink RLC data block
periodically, so as to notify the MS to send the RLC/MAC control message (e.g.,
packet downlink acknowledgement message) on the corresponding uplink block. For
a TBF, if the count of consecutive lost RLC/MAC control messages on the specifieduplink block is more than N3105 (N3105max), the timer T3195 will be started. Upon
expiry of the timer T3195, the network can reuse the TFI resources. The default value of
this parameter is 10. At Bijie, this parameter is set to 7.

different letters on the same key if you hold down the key for a while, select
validate to go back to the previous level of directory Select CMWAP, and
then select activate to complete the configuration.
Before accessing the network via WAP, check that a GPRS symbol exists on the
mobile phone, and then press the @ key on the mobile phone Select 3 (go to
URL) to enter Input the URL, e.g., wap.sina.com. However, the GAGEM does
not support Chinese format, so the texts are illegible. To resolve the problem
thoroughly, you can input the URL in the bookmarks.
2) Dialup access
Taking the configuration under WIN2000 as an example:
a) Connect the USB-serial port. This serial port should be COM1 (otherwise,
change it to COM1).
b) Add a standard 28800bps modem at COM1.
c) Add a new dialup connection. Select the new COM1 as the modem, and input
*99*1# as the dialup number. The highest rate is up to 57600bps.
d) In Network, deselect all the three options in PPP setting.
e) These steps are essential: In Attribute -> Advanced -> Extra initialization
