Determining access point base station

摘要

When an access process request signal for access to a connection network, from a terminal which exists in the same coverage area shared by a plurality of radio base stations, is received by one of the radio base stations, an access point base station is determined according to the resource information of the radio base stations by the connection network so as to transmit to the terminal, an access process base station modification request signal which requests that the access process request signal be transmitted to the radio base station that serves as the determined access point base station.

主权项

1. A network comprising a plurality of radio base stations having an overlapping coverage area one another, and a radio base station control device for controlling said plurality of radio base stations, wherein:
an access point base station is determined from among said plurality of radio base stations based on resource information of said plurality of radio base stations when an access procedure request signal for accessing said network is received at one of said plurality of radio base stations from a terminal which exists within the overlapping coverage area, and an access procedure base station change request signal is transmitted to said terminal for requesting said terminal to transmit the access procedure request signal to said radio base station which has been determined to be an access point base station for which said terminal performs an access procedure when a radio base station that is determined to be the access point base station is not a radio base station which has received the access procedure request signal from said terminal, wherein the terminal performs data communication with the determined access point base station after transmitting the access procedure request signal, said network is an ASN (Access Service Network) on WiMAX (Worldwide Interoperability for Microwave Access), upon receipt of function information indicative of available functions of said terminal from said terminal, determining said access point base station based on the function information and the resource information, and enabling information on the access procedure base station change request to be set in an SBC-RSP signal, and transmitting the access procedure base station change request to said terminal using the SBC-RSP signal.
