RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD

摘要

A radio communication system includes an EPC 100, a 3G network 200 and a mobile station 10 connectable to an external network 300 via any one of the EPC 100 and the 3G network 200. The communication system includes: a handover function unit configured to control a handover from the EPC 100 to the 3G network 200. The number of EPS bearers allowed to be set up with the mobile station 10 and the EPC 100 is larger than the number of PDP contexts allowed to be set up with the mobile station 10 and the 3G network 200. The handover function unit controls the handover in accordance with the number of the EPS bearers already set up with the mobile station 10 and the EPC 100 and the number of the PDP contexts to be newly set up with the mobile station 10 and the 3G network 200.
