Abstract
Some embodiments provide a method of associating Mobile Management Entities (MMEs) of an evolved packet system (EPS) and Voice over long term evolution (LTE) via Generic Access (VoLGA) network controllers (VANCs). The method includes at a serving VANC, receiving a registration message from a user equipment (UE). The registration message includes an assigned Globally Unique Temporary Identity (GUTI) of the UE and the serving VANC is provisioned with MME-to-VANC mapping information. The method extracts an identification of a MME from the GUTI and determines an associated VANC based on the provisioned MME-to-VANC mapping information. The method then sends a message from the serving VANC to the associated VANC, the message indicating that the serving VANC is now serving the UE.
