3G SGSN Service Configuration
The following configuration steps must be completed to allow the system to operate in a 3G network.
Step 1
Create the contexts needed. Refer to the System Element Configuration Procedures chapter in the System
Administration Guide.
Administration Guide.
Step 2
Create any interfaces needed in the appropriate context. Refer to the System Element Configuration Procedures chapter
in the System Administration Guide for IP (broadcast Ethernet) interfaces and for ATM interfaces.
in the System Administration Guide for IP (broadcast Ethernet) interfaces and for ATM interfaces.
Step 3
Configure SS7 routing domains. The SS7 routing domain is proprietary concept to provide a combined configuration
for the SS7 links, linksets, and related parameters. SS7 routing domain configurations are common to both SIGTRAN
and MTP3-B networks. Use the procedure in
for the SS7 links, linksets, and related parameters. SS7 routing domain configurations are common to both SIGTRAN
and MTP3-B networks. Use the procedure in
Step 4
Configure global title translations (GTT). The GTT configuration is used to set rules for GTT and to define the GTT
databases. Follow the procedure in
databases. Follow the procedure in
Step 5
Configure SCCP networks. The SCCP network (layer) provides services to protocol layers higher in the SS7 protocol
stack, for example RANAP and TCAP. The SCCP layer is also responsible for GTT. As well, all the SS7 routing
domains (created in step 3) will be associated with an SCCP network. Use the procedure in

domains (created in step 3) will be associated with an SCCP network. Use the procedure in
Step 6
Configure MAP services. The MAP service configuration is used by the SGSN service to communicate with many of
the nodes in the SS7 network, such as the HLR, EIR, GSM-SCF, GMLC and SMS-GMSC/SMS-IWMSC. Having an
isolated MAP configuration enables different application services to use the MAP service to communicate with other
MAP entities in the network. Use the procedure in

isolated MAP configuration enables different application services to use the MAP service to communicate with other
MAP entities in the network. Use the procedure in
Step 7
Configure IuPS services. A set of parameters define the communication path between the SGSN service and radio
network controllers (RNCs) in a UMTS IuPS service. Use the procedure in
network controllers (RNCs) in a UMTS IuPS service. Use the procedure in
Step 8
Configure SGTP services. The SGTP service configures the parameters used for GTP Tunneling. At a minimum,
interfaces for GTP-C and GTP-U must be configured. Use the procedure in
interfaces for GTP-C and GTP-U must be configured. Use the procedure in
Step 9
Configure the SGSN service. All the parameters specific to the operation of an SGSN are configured in the SGSN
service configuration mode. SGSN services use other service configurations like MAP (map-service) and IuPS (iups-
service) to communicate with other elements in the network.
service configuration mode. SGSN services use other service configurations like MAP (map-service) and IuPS (iups-
service) to communicate with other elements in the network.
Step 10 Configure DNS clients. This configuration enables domain name resolution and specifies the DNSs to use for lookup.
Step 11 Optional: Configure operator policies. Operator policies are not required for SGSN operation, however, they provide
the operator with a powerful method for determining call handling. SGSN operator policies specify rules governing the
services, facilities and privileges available to a single subscriber or groups of subscribers. Use the procedure in
Configuring SGSN Operator Policies.

Configuring SGSN Operator Policies.
Step 12 Configure GTPP Accounting. This configures GTPP-based accounting for subscriber PDP contexts. Use the procedure
Step 13 Configure ATM PVCs and bind them to interfaces or SS7 links as needed. Refer to Creating and Configuring ATM
Interfaces and Ports in the System Administration Guide.
