Abstract

A system and method for a partner network sharing architecture is provided. In an embodiment a piece of user equipment that is part of a partner network is handed off or otherwise attached to a wholesale network.

18. A method of partner identification in a shared network entity, the method comprising:

receiving a handover communication, the handover communication comprising a list of equivalent public landmobile network (PLMN) IDs; and

analyzing the handover communication using a processor of the shared network entity, the analyzing the handover communication further comprising looking in a pre-arranged location within the list of equivalent PLMN IDs to find an indication of an originating partner network identity, wherein the pre-arranged location is known by the shared network entity prior to the receiving the handover communication.

19. The method of claim 18, wherein the handover communication is a handover restriction list.

20. The method of claim 18, wherein the pre-arranged location is a first location in the list of equivalent PLMN IDs.

21. The method of claim 18, wherein the pre-arranged location is a first known partner network.

22. The method of claim 18, wherein the indication of the originating partner network identity is a PLMN ID of the partner network.

23. The method of claim 18, wherein the indication of the originating partner network identity is a PLMN ID of a non-partner network.

24. The method of claim 18, wherein the indication of the originating partner network identity is a null.

25. A shared network entity comprising:

a memory; and

a processor coupled to the memory and configured to;

receive a handover communication; and

analyze the handover communication, wherein the analyzing the handover communication further comprises looking in a pre-arranged location within a list of equivalent Public Land Mobile Network (PLMN) IDs within the handover communication to find an indication of a partner network identity, wherein the shared network entity knows the pre-arranged location prior to the receiving the handover communication.

26. The shared network entity of claim 25, wherein the handover communication is a handover restriction list.

27. The shared network entity of claim 25, wherein the pre-arranged location is a first location in the list of equivalent PLMN IDs.
