Base Station MME Pool Mapping for Wireless Mobility Management

The patent segments the service area into multiple tracking areas, each associated with a specific MME pool. The eNB maintains a mapping table that divides the coverage area into distinct regions, each region corresponding to a particular MME pool. This segmentation allows the system to manage UE mobility in a distributed manner across multiple MME pools while maintaining clear boundaries and responsibilities for each pool.

The patent introduces a mapping table as an intermediary data structure that stores the correspondence between tracking areas and MME pools. This mapping table acts as a mediator that enables the eNB to determine which MME pool should handle a particular UE based on its current tracking area, thereby simplifying the mobility management process across multiple non-overlapping MME pools.

The patent performs preliminary allocation of S-GW and P-GW resources based on the UE's initial connection request and the determined MME pool. By pre-establishing the resource allocation path before actual data transmission begins, the system reduces latency without requiring complex real-time dynamic allocation during data flow.

The patent implements local quality optimization by allocating S-GW and P-GW resources specifically tailored to each UE's geographic location and associated MME pool. Each MME pool has its designated set of S-GW and P-GW resources, ensuring that UEs are connected to the nearest available resources, thereby minimizing transmission latency while maintaining manageable allocation complexity through localized resource pools.
