CORE-NETWORK DISTRIBUTED RADIO COMMUNICATION SYSTEM AND CONNECTION CONTROL METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a system and a connection control method that are short in a communication interruption time even if a user terminal moves in a core-network distributed radio communication system.SOLUTION: When a user terminal 10 stays in an edge area 210a in an accommodation area 200a, a core-network distributed radio communication system forms second connection via a core network 100b having an adjacent accommodation area 200b in addition to first connection via the accommodation area 200a. When the user terminal 10 moves from the accommodation area 200a to the accommodation area 200b, it switches data communication from the first connection to the second connection.SELECTED DRAWING: Figure 3
