Methods and apparatus for optimizing paging mechanisms using device context information

摘要

Methods and apparatus enabling a wireless network to optimize paging channel operation, based on mobile device context information. In one embodiment, the wireless network is a cellular network (e.g., LTE-Advanced), and both base stations and cellular user devices dynamically exchange and maintain a paging agreement. The paging agreement limits the paging channel operation, thereby minimizing unnecessary scanning and usage of irrelevant radio resources. Such paging mechanisms are limited to the air interface between the base station and the mobile device, and are compatible with existing legacy devices and network entities. Networks with appropriately enabled user devices may improve their resource utilization. Base stations may advantageously reclaim freed-up cellular resources to support other services.

1. A mobile device communicating with a multi-cell network comprising a plurality of base stations and a core portion, the mobile device comprising:
a digital processor; a radio interface configured to communicate with the processor and a multi-cell network; and a storage device coupled to the processor, the storage device comprising computer executable instructions that, when executed by the digital processor:
specify only a subset of a plurality of base stations to perform paging, where the plurality of base stations are associated with a tracking area; anddirect communication of the specified subset of base stations only to the base stations without communicating the specified subset of base stations to the core portion.
