Abstract

A method and system for managing handover where a database that receives location information about a moving object includes information regarding which base station is used in a current radio link connection and which base stations were used from historic radio link connections. Using the base station radio link history of the object and an electronic map, a processor coupled to the memory of the database selects which physical path the moving object is using. Upon matching the object's path with a history of path routes on the list, the processor will apply an optimized handoff sequence to the moving object. The optimized route can be derived from an algorithm that processes previous historical data from moving objects traveling on the same route. Methods of providing the location of moving objects via location sensors may be used to provide the database with higher resolution information about a moving object's location on an electronic map and allow further enhancement of the handoff optimization. Generally, location data is used to quickly determine which route the moving object is using and more quickly assign an optimized handoff sequence. Historical data along known routes can include time and spatial information to be processed by the routing algorithm. The database may reside in a central location or within each moving object or a combination of both.
