Abstract:
1. A method comprising: maintaining, at a mobility management entity (MME) in a communication network, a list of eNodeBs from which a user equipment (UE) was actively communicating with the communication network, the communication network including a plurality of eNodeBs arranged into at least one tracking area; receiving a page request for the UE at the MME; sending a first paging request to a first set of eNodeBs at least in part based on the list; identifying a second set of eNodeBs to receive a second paging request, the second set including a first subset of eNodeBs at least in part based on subscriber location activity of the UE, the subscriber location activity including one or more location identifiers associated with the UE, a window of time based on one or more system time stamps of the MME, and a subscriber identifier associated with the UE, and the second set having at least some different eNodeBs than the first set; adding, to the second set of eNodeBs to receive the second paging request, a second subset of eNodeBs including one or more eNodeBs not included in the first subset, the second subset of eNodeBs having been selected at least in part based on the UE having communicated with the eNodeBs of the second subset more recently, and a fewer numbers of times, than with at least one of the eNodeBs of the first subset; and sending the second paging request to the second set of eNodeBs, if a response is not received responsive to the first paging request.
