RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD

摘要

A radio communication system comprises an EPC (100), a 3G network (200), and a wireless terminal (10) connectable to an external network (300) via the EPC (100) or the 3G network (200). The radio communication system is equipped with a handover function unit for controlling handovers from the EPC (100) to the 3G network (200). The number of EPS bearers that can be set via the wireless terminal (10) and the EPC (100) is greater than the number of PDP contexts that can be set via the wireless terminal (10) and the 3G network (200). The handover function unit controls the handovers according to the number of EPS bearers already having been set via the wireless terminal (10) and the EPC (100) and the number of PDP contexts to be set via the wireless terminal (10) and the 3G network (200).
