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： 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： 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.
摘要翻译：响应于来自移动台的BCMCS服务请求，基站单独通知移动台所请求的BCMCS服务是否可用。因此，基站可以仅包括在广播开销消息中实际广播所必需的广播信道信息，并且如果BCMCS业务停止或不可用，则基站可以命令移动台中断BCMCS业务，从而减少负载系统资源。

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 method and apparatus are provided for managing session information of an access terminal (AT) that has moved from a source subnet to a target subnet in a mobile communication system for high-speed data transmission. The AT transmits a message with a prior universal access terminal identifier (UATI) to a target access network (AN) to perform session negotiation with the target AN of the target subnet. The target AN transmits a message with the prior UATI to a target packet control function (PCF) to request retrieval of session information of the AT. The target PCF sends a request for transmission of prior session information for the AT to a source PCF of the source subnet, found using the prior UATI. The target PCF receives the prior session information from the source PCF and retrieves the session information of the AT using the received prior session information.

摘要： An apparatus and a method for changing a MultiCast and BroadCast Service (MCBCS) broadcasting channel in a Broadband Wireless Access (BWA) system are provided. The method includes, if an MCBCS initialization request message is received from an MCBCS server, sending a burst reservation request message for MCBCS burst allocation to one or more Base Stations (BSs) in a corresponding Multicast and Broadcast Service (MBS) zone, and if a burst reservation response message is received from at least one of the one or more BSs, sending a Resource Reservation (RR) request message for each channel to the at least one of the one or more BSs for establishing data channels for each channel broadcast by the MCBCS server. Accordingly, a channel transition delay time resulting from a user's channel change can be reduced.
