Abstract:
A wireless communication system, including a distributed home location register, for tracking the location of mobile terminals, comprising:a Mobility Control Point (MCP) mechanism for controlling communications in a plurality of geographically spaced zones and providing storage capabilities for service information relating to mobile terminals; a plurality of Central Processing Units (CPUs) associated with each MCP, each CPU including a corresponding Home Location Register (HLR), for storing enabled service information of a subset of mobile terminals serviced by the plurality of zones;a plurality of Visitor Location Registers (VLRs), associated with each CPU and corresponding HLR, for temporarily storing mobile terminal data and connected to the associated CPU for communicating with the plurality of CPUs and corresponding HLRs;means for tracking the location of the mobile terminals from one zone to another; anda Location Tracking Service Manager (LTSM) configured to maintain proper load distribution throughout the system, wherein the LTSM includes:means for dynamically partitioning a plurality of mobile terminal identifiers used for identifying associated service information into blocks;means for storing a partitioning of mobile terminal identifiers into a memory map; andmeans for transmitting the memory map.
