Bestimmung eines Cross-over-Routers in einem mobilen Kommunikationsnetz

摘要

A mobile communication system 100 according to the present invention comprises handover control apparatus 1 and radio terminal unit 10. The handover control apparatus 1 controls handover of radio terminal unit 10 between access routers 31-34 provided in respective base stations 21-24 for radio communication with the radio terminal unit 10. The handover control apparatus 1 counts the number of relay routers for every candidate access router 32-34 for a destination of the radio terminal unit 10, from a gateway device 52 and determines a COR on the basis of the number of relay routers for every access router 32, 33, 34 thus counted.
