Systems and methods are disclosed that provide identities of multiple serving elements of user equipment (UE). In one embodiment, a subscriber server of a packet-switched data network stores data for the UE, which is served by the packet-switched data network. The subscriber server receives a user data request from a network element over a Diameter interface. In response to the user data request, the subscriber server identifies multiple serving elements where the UE is presently registered in the packet-switched data network and/or a legacy network. The subscriber server inserts identifiers for the multiple serving elements where the UE is presently registered in a user data answer, and transmits the user data answer to the network element over the Diameter interface. |
