Patent ID: 7099655

Claim:
A method for receiving a broadcast service by a mobile station in a wireless broadcast service system comprising said mobile station existing in a service area, a base station capable of connecting a wireless channel to said mobile station, a packet data serving node for connecting said base station to a packet communication network, a broadcast server connected to said packet communication network, and an authentication server connected to said packet communication network, the method comprising: (a) performing user authentication by setting up a connection with the authentication server, and receiving, if the user authentication is passed, information on available broadcast services from the broadcast server; (b) registering a desired broadcast service in the packet data serving node based on said received information so that said packet data serving node assigns a network resource for the desired broadcast service, wherein said step of registering in the packet data serving node further comprises transmitting a multicast IP address for the desired broadcast service to the packet data serving node and controlling the packet data serving node to compare the received multicast IP address with an authorized multicast IP address received from the authorization server for registration control and inquiry generation; (c) if the received multicast IP address is identical to an authorized multicast IP address and the desired broadcast service is authorized by the packet data serving node, registering said desired broadcast service in said base station so that said base station assigns a wireless broadcast channel and a network resource for the desired broadcast service; and (d) receiving broadcast data for said desired broadcast service over said broadcast channel assigned by said base station.
