Abstract
This disclosure relates to systems and methods for paging devices in a communication network. A network device providing mobility management through control messaging can be assigned a number of cell sites in multiple tracking areas. The network device such as a mobility management entity (MME) can use a subscriber-aware implementation to provide a hierarchy for contacting a mobile device with a page. The subscriber-aware implementation can be tailored to analyze subscriber activity such as frequency and timing, to page a subset of the total number of cell sites in multiple tracking areas based on the subscriber activity, and to expand the subset after unsuccessful attempts to page the mobile device.

21. 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 list also including indications of tracking areas of eNodeBs of the list, wherein each tracking area includes a plurality of eNodeBs of the communication network; receiving a page request for the UE at the MME; sending a first page request to eNodeBs in the tracking area of an eNodeB with which the UE was last actively communicating; identifying a set of at least one tracking area to flood based on the list maintained at the MME, wherein at least one tracking area identified in the list maintained by the MME is excluded from the set of at least one tracking area to flood based on a frequency with which one or more eNodeBs of the at least one tracking area was used by the UE to actively communicate with the communication network; and sending an additional page request to a plurality of eNodeBs of each tracking area of the identified set of at least one tracking area to flood. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. An apparatus comprising:
-
a storage medium configured to store a list of eNodeBs from which a user equipment (UE) was actively communicating with a communication network, the list also including indications of tracking areas of eNodeBs of the list, wherein each tracking area includes a plurality of eNodeBs of the communication network; a physical interface configured to; receive a page request for the UE; send a first page request to eNodeBs in the tracking area of an eNodeB with which the UE was last actively communicating; a processing unit configured to identify a set of at least one tracking area to flood based on the list, wherein at least one tracking area identified in the list is excluded from the set of at least one tracking area to flood based on a frequency with which one or more eNodeBs of the at least one tracking area was used by the UE to actively communicate with the communication network; and wherein the physical interface is further configured to send an additional page request to a plurality of eNodeBs of each tracking area of the identified set of at least one tracking area to flood. - View Dependent Claims (29, 30, 31, 32, 33, 34)

35. A computer-readable non-transitory medium comprising one or more instructions that when executed by a processor configure the processor to cause the performance of operations comprising:
-
maintaining a list of eNodeBs from which a user equipment (UE) was actively communicating with a communication network, the list also including indications of tracking areas of eNodeBs of the list, wherein each tracking area includes a plurality of eNodeBs of the communication network; receiving a page request for the UE; sending a first page request to eNodeBs in the tracking area of an eNodeB with which the UE was last actively communicating; identifying a set of at least one tracking area to flood based on the list, wherein at least one tracking area identified in the list is excluded from the set of at least one tracking area to flood based on a frequency with which one or more eNodeBs of the at least one tracking area was used by the UE to actively communicate with the communication network; and sending an additional page request to a plurality of eNodeBs of each tracking area of the identified set of at least one tracking area to flood. - View Dependent Claims (36, 37, 38, 39, 40)
