Method for providing broadcast service in a CDMA mobile communication system
First Claim
1. 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;
(c) if 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.

Abstract
Disclosed is a method for providing a broadcast service in a mobile communication system using code division multiple access (CDMA) technology. The novel method controls transmission of broadcast service data according to base station areas by registering a mobile station with a broadcast service. For that purpose, the mobile station requests an authentication server to authenticate a desired broadcast service, and registers the authenticated broadcast service in a packet data serving node via a base station so that the base station and the packet data serving node can set up a transmission path for the broadcast service. The method increases the efficiency of base station resources by controlling transmission times of base stations, and the packet data serving node can perform accounting on the broadcast service of the mobile station. Further, a plurality of registered mobile stations constitute a group, and broadcast service data is transmitted from one mobile station to other mobile stations within the group.

7. A method for providing a broadcast service to a mobile station by a base station in a wireless broadcast service system comprising the mobile station existing in a service area, the base station capable of connecting a wireless channel to said mobile station, a packet data serving node for connecting the base station to a packet communication network, a broadcast server connected to the packet communication network, and an authentication server connected to the packet communication network, the method comprising:
-
(a) upon receiving a broadcast service registration request from the mobile station, determining whether the requested broadcast service is already being provided;
(b) if the requested broadcast service is not being provided, registering the requested broadcast service in the packet data serving node so that the packet data serving node assigns a network resource for the requested broadcast service; and
(c) if the requested broadcast service is authorized by the packet data serving node, assigning a wireless broadcast channel for the broadcast service and transmitting broadcast data for the requested broadcast service received from the packet data serving node to the mobile station over the assigned broadcast channel. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method for providing a broadcast service to a mobile station by a packet data serving node in a wireless broadcast service system comprising the mobile station existing in a service area, a base station capable of connecting a wireless channel to said mobile station, the packet data serving node for connecting the base station to a packet communication network, a broadcast server connected to the packet communication network, and an authentication server connected to the packet data communication network, the method comprising:
-
(a) receiving information on broadcast services available for the mobile station from the authentication server;
(b) upon receiving a registration request for a broadcast service desired by the mobile station, assigning a network resource for the requested broadcast service based on the received information on the available broadcast services; and
(c) upon receiving a registration request for the requested broadcast service from the base station, transmitting broadcast data for the requested broadcast service received from the broadcast server to the mobile station through the base station, using the assigned network resource. - View Dependent Claims (15, 16, 17, 18, 19, 20)
