Configuring a GPRS Service (2.5G only)
All the parameters specific to the operation of an SGSN in a GPRS network are configured in a GPRS service
configuration. GPRS services use other configurations like MAP and SGTP to communicate with other elements in the
network. The system can support multiple GPRS services.
configuration. GPRS services use other configurations like MAP and SGTP to communicate with other elements in the
network. The system can support multiple GPRS services.
To configure a GPRS service:
Step 1
In Context configuration mode, create a GPRS service instance and give it a unique name.
Step 2
Specify the context in which the accounting parameters have been configured.
Step 3
Create a PLMN definition for the GPRS service to include the identity of the mobile country code (MCC) and the
mobile network code (MNC).
mobile network code (MNC).
Step 4
Associate other services (such as a MAP or Gs or SGTP service) and their configurations with this GPRS service. This
command should be repeated to associate multiple service types and/or multiple instances.

Step 5
Define the network service entity identifier (NSEI) of one or more remote SGSNs with their location area code (LAC)
and routing area code (RAC). This step can be repeated to associate multiple peer-NSEIs.
and routing area code (RAC). This step can be repeated to associate multiple peer-NSEIs.
Step 6
Specify the E.164 number to identify this SGSN.
Step 7
Configure the charging characteristic(s).
Step 8
Specify the types of CDRs to generate.
