Configuring Gn Interface Selection Based on an Operator Policy

(S4 Only, Optional)

The S4-SGSN uses the S4 interface to communicate with EPC-capable UEs. However, operators have the to option to
create a call-control-profile that enables the S4-SGSN to forcefully select the Gn interface for EPC-capable UEs.

Use this procedure to forcefully select the Gn interface for EPC-capable UEs:

Step 1

Access Call Control Profile Configuration Mode.

Step 2

Create a call-control-profile.

Step 3

Configure the SGSN to forcefully select the Gn interface.

Example Configuration

config

call-control-profile <cc_profile_name>

sgsn-core-nw-interface { gn | s4 }

end

Notes:



sgsn-core-nw-interface specifies the interface that EPC-capable UEs will use to communicate with the packet

core gateways (GGSN/SGW). The default setting for EPC-capable UEs is s4.
