Activating and testing Gb over IP
1.1
Creating and activating the Gb interface over IP
The Gb interface between the BSC and SGSN is established in two phases: first
you configure the IP address, then you set up the IP gateway. The system builds
the BSSGP Virtual Connections automatically when GPRS is taken into use on a
cell level.

Activating and Testing BSS10103: Gb over IP
For deactivation instructions, see Deactivating Gb over IP.
Before you start
.
You must have a licence covering Gb over IP installed. The licence is
based on capacity, that is, the number of PCUs using Gb over IP. When
installing the licence, the initial state should be set to 'ON'.
.
In static IP configuration it does not matter which end of the interface you
configure first.
In dynamic IP configuration, you should first configure the SGSN end of
the interface. This is because the BSC will attempt to run the size and
configuration procedures immediately after creating the IP network service
virtual link (NS-VL).
.
Both IPv4 and IPv6 are supported in the Nokia implementation of Gb over
IP. Configuration of the PCU IP stack is handled with the commands of
command group QR when IPv4 is used, and with the commands of the
command group Q6 when IPv6 is used.
.
If you want to use the DNS name parameter instead of IP address with
either configuration, you must first configure the DNS server address to the
BSC with the MML command QRK or Q6K, and the DNS server must be
properly configured.
Steps
1.
Check that the licence covering Gb over IP has been installed (W7I).
ZW7I:LIC,FULL:LIC=<licence code>:;
For instructions on installing licences, see Licensing in BSC.
2.
Check the Gb over IP feature state (W7I).
ZW7I:FEA,FULL:FEA=7;
3.
Turn the Gb over IP feature state 'ON' if needed (W7M).
ZW7M:FEA=7:ON;
4.
Check that the feature state change of Gb over IP succeeded (W7I).
ZW7I:FEA,FULL:FEA=7;
5.

Create network interfaces (QRN).

Activating and testing Gb over IP
Note
In the dynamic configuration, you can use either physical or logical IP
addresses, but in the static configuration you must only use logical addresses.
ZQRN:<unit type>,<unit index>:<plug-in unit type>,
<plug-in unit index>:<interface name>:<ip address>,
<L/P>,<DEL>:<netmask length>:<state>:<mtu>;
6.
Create static route(s) (QKC) (optional).
ZQKC:<unit type>,<unit index>:<plug-in unit type>,
<plug-in unit index>:<destination IP address>,
<netmask length>:<gateway IP address>:<route type>;
Note
You should check that the LAN supervision is configured properly. See LAN
Manual for more information on LAN supervision.
7.
Check the IP configuration (QRI) (optional).
ZQRI:<unit type>,<unit index>:<plug-in unit type>,
<plug-in unit index>:<interface name>:<display
unit's attached interfaces>;
8.
Create a Packet Service Entity (FXA).
ZFXA:PSEI=<packet service entity identifier>,
BCSU=<base station controller signalling unit>,
PCU=<packet control unit>;
9.
To implement this step, choose one of the following alternatives:
a.
Create the network service virtual link (NS-VL) using a
dynamic IP configuration (FXK).
Note
The NSEI has to be in line with the SGSN configuration, when the IP subnetwork is used.

ZFXK:NSVLI=<network service virtual link
identifier>,NAME=<network service virtual link
name>,NSEI=<network service entity identifier>,
PSEI=<packet service entity identifier>:
LPNBR=<local UDP port number>,PRE=Y:RIP=<remote
IP address>,RPNBR=<remote UDP port number>;
You can only create one NS-VL per NSE in the BSC. If the SGSN
supports more IP endpoints, the system will create several IP
endpoints to the remote end. The maximum number of local
endpoints is one. The maximum number of remote endpoints is 4
with PCU1, and 16 with PCU2.
Before the system can initialise the Gb interface for the NSEI, you
must configure the NS-VLs (that is, the IP endpoints) to SGSN.
Note
The remote IP address parameter determines, whether the local IP
address that is used is of the IPv4 or IPv6 type. The remote and local ends of
the NS-VL must use the same address type. Both address types can be
simultaneously configured to the PCU.
If you use the remote host name parameter instead of remote IP
address, the PCU will use which ever address type is configured to it. If
both types are configured, IPv4 is the default type.
b.
Create the network service virtual link (NS-VL) using a static IP
configuration (FXK).
Note
The NSEI has to be in line with SGSN, when the IP sub-network is used.
ZFXK:NSVLI=<network service virtual link
identifier>,NAME=<network service virtual link

Activating and testing Gb over IP
If you want to use load balancing between remote IP endpoints (NSVLs), or if you want to use different IP endpoints for signalling and
data traffic, create more remote IP endpoints (NS-VLs) with the FXK
command. The maximum number of local endpoints is one. The
maximum number of remote endpoints is 4 with PCU1, and 16 with
PCU2.
10.
Check the creation and state of the NS-VL (FXI).
ZFXI:NSVLI=<network service virtual link
identifier>;

Testing the activation of Gb over IP
You can monitor the Gb over IP performance with 98 Gb over IP Measurement.
Steps
1.
Create the measurement (TPM).
If the measurement is not already defined, create definitions and schedules
for it.
ZTPM:GPRS,GBIP:<measurement day>,<measurement
interval>,<output interval>;
2.
Start the measurement (TPS).
ZTPS:GPRS,GBIP;
3.
Verify the success of the activation.
At the end of the measurement period, check the measurement data in
Nokia NetAct or in BSC using the MEFICO tool. For more information,
see
.
Reporter and Performance Management Principles in NetAct
documentation.
.
Converting BSC Measurement and Observation Files with MEFICO
Expected outcome
Counters 098000 NS_ALIVE MSG SENT BY PCU and 098001
NS_ALIVE_ACK MSGS FROM SGSN are updated.
Unexpected outcome
Counter 098002 NS_ALIVE MSGS SENT BY PCU RETRY is updated.

1.3
Modifying the remote IP endpoint signalling and
data weight (static configuration only)
Steps
1.
Modify the signalling and data weights of the remote IP endpoint
(FXJ).
You can only modify the signalling and data weights of the static
configuration.
ZFXJ:NSVLI=<network service virtual link
identifier>::NEWRDW=<new remote data weight>,
NEWRSW=<new remote signalling weight>::;
2.
Check the creation and state (FXI).

Deactivating and testing Gb over IP
For a description of Gb over IP, see Gb over IP in BSC.
For activation instructions, see Activating and testing Gb over IP.
Before you start
Before deactivating Gb over IP, disable GPRS on a cell level. For instructions, see
Activating and Testing BSS9006: GPRS.
You do not need to lock the channel(s) in the IP configuration.
Steps
1.
Delete the network service virtual link (NS-VL) (FXH).
Note
You cannot delete an NS-VL, if it is the only one in a certain NSE and the NSVL has cells connected to it.
ZFXH:NSVLI=<network service virtual link
identifier>;
Refer to Gb Interface Handling (FX) for more information on the command
parameters.
In the static configuration, you must delete every NS-VL separately.
2.
Check the deletion of NS-VLs (FXI).
ZFXI:NSVLI=<network service virtual link
identifier>;
3.
DN05135155
Issue 1-0 en
Delete the Packet Service Entity (FXE).
# Nokia Corporation
17 (19)
Activating and Testing BSS10103: Gb over IP
The deletion is not allowed if there are NS-VLs or NSEs configured to the
PSE.
ZFXE:<packet service entity identifier>;
Note
The steps from step 4 onwards are only necessary if you want to disconnect
the PCU.
4.
Delete static routes (QKA).
ZQKA:<route number>:<unit type>,<unit index>:<plugin unit type>,<plug-in unit index>;
5.
Remove the network interface (QRG).
ZQRG:<unit type>,<unit index>:<plug-in unit type>,
<plug-in unit index>:<interface name>;
6.
Check the deactivation (QRI).
ZQRI:<unit type>,<unit index>:<plug-in unit type>,
<plug-in unit index>:<interface name>:<display
unit's attached network interfaces>;
7.
To disable the use of Gb over IP altogether, turn the feature state
'OFF' (W7M).
ZW7M:FEA=7:OFF;
Expected outcome
After you turn the feature state parameter 'OFF', the Gb over IP -related
parameters and commands are no longer visible in the MML command
interface. You can verify this by trying to use, for example the FXL
command.
