RADIO COMMUNICATION SYSTEM, AND METHOD FOR REPORTING CALL PROCESS INFORMATION IN THE RADIO COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To provide a radio communication system for allowing a base station to recognize failure when tunnel establishment fails between a session information management node and a mobile station, and for allowing the base station or the mobile station to retry the establishment of the tunnel. SOLUTION: The radio communication system includes a plurality of mobile stations, a plurality of base stations, and a plurality of session information management devices. Each mobile station performs radio transmission and reception of packets with each base station. Each base station is connected to the plurality of session information management devices, and a message is tunneled through each base station to be transmitted and received between each session information management device and each mobile station. A base station transmits a tunnel creation request message to a mobile station. The mobile station creates a tunnel creation result response message, including the result of processing based on the tunnel creation request message, and reports the message to the base station.
