epc-ue
Configure this keyword to select the HSS interface for EPC capable subscribers. For other subscribers the MAP
interface will be selected. This keyword will be applicable only when both MAP and HSS interfaces are configured in
the Call-control profile. If this keyword is not configured then SGSN follows existing logic for interface selection. The
interface selection based on UE capability is done only at the time of Attach / new SGSN RAU / SRNS. Once the
interface is selected, the subscriber remains in same interface till the UE moves out of the SGSN.

Usage
Use of this command requires an S6d license.
The SGSN provides a mechanism to associate a MAP service with call control profile. It is possible that both
MAP service and HSS peer service are associated with the call control profile. If the interface preference
selected is “hlr”, the MAP protocol is used to exchange messages with the HLR. If the interface preference
selected is “hss”, the Diameter-protocol is used to exchange messages with the HSS.
