Configuring an SGSN Service (3G only)
All the parameters specific to the operation of an SGSN in a UMTS network are configured in an SGSN service
configuration. SGSN services use other service configurations like MAP (map-service) and IuPS (iups-service) to
communicate with other elements in the network.
configuration. SGSN services use other service configurations like MAP (map-service) and IuPS (iups-service) to
communicate with other elements in the network.
To configure an SGSN service:
Step 1
In Context configuration mode, create an SGSN service and give it a unique name.
Step 2
Specify the Core Network (CN) ID that will identify this SGSN service on the CN.
Step 3
Specify the E.164 number to identify this SGSN service.
Step 4
Configure the maximum number of PDP contexts that a UE can establish.
Step 5
Specify the MAP service and the context in which it is configured that this SGSN service should use.
Step 6
Specify the IuPS service name and the context in which it is configured for the SGSN service to use for RAN protocol
settings.
settings.
Important:
If a direct tunnel is to be established, GTP-U direct tunneling must be enabled in both the
IuPs service and in the call-control-profile. For the IuPS service, the DT must be enabled per RNC; DT is
enabled by default on RNCs.
enabled by default on RNCs.
Step 7
Specify the SGTP service and the context in which it is configured for this SGSN service to use for GTP configuration.
Step 8
Specify the CDR types that the SGSN service should generate.
Step 9
Specify the context in which GTPP accounting is configured. If the accounting context is not specified the current
context is assumed.
context is assumed.
Step 10 Configure the charging characteristics profile. (Number of buckets for the max change condition, volume limit, time
limit, and tariff time switch values should be defined individually according to requirements for each of the charging
characteristics profiles.
characteristics profiles.
Step 11 Optional: Specify the Gs service name and the context in which it is configured.
Important:
Session Management (SM) and GPRS Mobility Management (GMM) settings can be
configured as needed using the SGSN configuration mode commands;
