A broadcast service method and system for use in wireless communication system. The broadcast service method and system for a wireless communication system according to the present invention assigns individual unique BCMCS IDs to a plurality of BCMCS controllers, such that it can recognize a changed BCMCS controller within a cell in which an MS is located, BSPM (Broadcast Service Parameter Message) effectiveness, the BCMCS conversion, etc.
摘要:
In response to a BCMCS service request from a mobile station, a base station separately informs the mobile station whether the requested BCMCS service is available. Thus, the base station can include only broadcast channel information necessary for actual broadcast in a broadcasting overhead message, and if the BCMCS service is stopped or unavailable, the base station can order the mobile station to interrupt the BCMCS service, thereby reducing the load on system resources.

摘要:
A system and method for synchronizing Broadcast/Multicast Service (BCMCS) traffic in a mobile communication system connected to a BCMCS server. A Packet Data Service Node (PDSN) receives a BCMCS content frame from the BCMCS server, and transmits a corresponding Generic Routing Encapsulation (GRE) packet BCMCS content frame, including a sequence number and a timestamp value indicating when the GRE packet BCMCS content frame is transmitted, to Packet Control Functions (PCF) connected downstream of the PDSN. Each of the PCFs determines whether the GRE packet BCMCS content frame received from the PDSN is valid, based on the sequence number included therein. If the GRE packet BCMCS content frame is valid, the PCF transmits the frame to its lower nodes connected downstream of the PCF, while synchronizing the frame transmission, based on the timestamp value included in the frame.
摘要:
A handoff method between a source network to which a terminal is connected in order of a Base Station (BS) and an Access Service Network (ASN), and a target network to which the terminal is connected in order of a Packet Data Service Node (PDSN), a Packet Control Function (PCF) and an Access Network (AN). The terminal sends a handoff request message with AN information of the target network to the ASN via the BS. The ASN forwards the handoff request message to the PCF via the PDSN using the AN information. Upon receipt of the handoff request message, the PCF sends a request for session information to the ASN via the PDSN. The PDSN sends a request for context information to the ASN. Upon receipt of the session information request and the context information request, the ASN transfers the context information to the PDSN and transfers the session information to the AN via the PDSN and the PCF.
摘要:
An encryption processing system and method are provided in a mobile communication system having an AT, an AN for sending packet data to the AT on a radio channel, a PCF for controlling the AN, and a PDSN for sending packet data to the AN through the PCF. The AT encrypts a packet generated upon user request and sends the encrypted packet on a radio channel. If it is indicated that the packet received from the AT was encrypted, the AN requests encryption information of the AT to the PCF and decrypts the encryption information received from the PCF. Upon receipt of the request of the encryption information of the AT from the AN, the PCF determines whether the AT is authenticated, extracts the encryption information of the AT if the AT is authenticated, and sends the extracted encryption information to the AN.

摘要:
Disclosed is a Quality-of-Service (QoS) Support method in a mobile communication system including an access terminal, an access network for performing packet data communication with the access terminal, a packet control function for controlling transmission and reception of packet data between the access network and the access terminal, and a packet data service node for exchanging packet data with the packet control function. The access terminal maps a requirement based on an application characteristic to an IP QoS parameter, generates a resource reservation protocol message, and transmits the resource reservation protocol message to the packet data service node. The packet data service node maps IP QoS information to be transmitted to the access terminal to QoS information needed in the access network, and transmits the mapping result to the access network via the packet control function. The access terminal receives data including QoS information from the packet data service node, and performs communication according to the QoS information.
摘要:
A system and method for de-registering a Broadcast/Multicast Service (BCMCS) in a high-rate packet data system including an access network (AN) for performing radio communication with an access terminal (AT), a packet control function (PCF) for processing packet data communication, and a packet data service node (PDSN) connected to a BCMCS contents server (CS) via a packet communication network is provided. In the system and method, the access network receives a de-registration message for a release request of a BCMCS service from the access terminal. The access network transmits a BCMCS release message including BCMCS information with a release request, to the packet control function. The packet control function transmits a BCMCS registration request message including the BCMCS information to the packet data service node. The packet data service node performs a release and accounting process on a corresponding BCMCS service based on the BCMCS information.
摘要:
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.
