摘要:
Disclosed is a way to solve a problem of an operation error, which may occur in transmitting a Binding Update (BU) or Registration ReQuest (RRQ) message for a mobile node to a home agent due to the fact that a PDSN supports a Proxy Mobile Internet Protocol (PMIP) for the mobile terminal and the corresponding mobile node supports a client mobile IP when there is the mobile node using the client mobile IP in a 3GPP2 mobile communication system supporting the PMIP, thereby enabling efficient communication.

A method, apparatus, and system for negotiating a session between an access terminal (AT) and an access network (AN) that can simplify a repeated negotiation procedure when the session is configured/updated/deleted between the AT and the AN. The AN performs protocol-by-protocol negotiations with the AT for a session configuration. The AN sends, to the AT, a soft configuration complete message including a continue bit indicating if another session configuration is added. The AN and the AT store a negotiated session configuration mapped to a personality index indicated in the message. When all session configurations have been completed, the AN and the AT determine if a session configuration currently in use has been changed. If the session configuration in use has not been changed, the AT and the AN maintain a physical channel. Moreover, the AN sends information indicating if a specific session configuration is applied after session configuration negotiation is completed.

A method for receiving resources allocated from a base station by a terminal in an OFDMA mobile communication system. The method includes receiving, for a data channel, a number of first components, which indicates an amount of resources used with a first resource allocation scheme, and a number of second components, which indicates an amount of resources used with a second resource allocation scheme, from the base station over a common control channel; determining first and second identifier lengths of channel elements for the first and second resource allocation schemes according to the number of first components and the number of second components; receiving resource allocation information including an identifier indicating at least one channel element allocated to the terminal, over a data control channel using one of the identifier lengths; and transmitting and receiving data over a resource of a channel element indicated by the received identifier.

Disclosed is a method for receiving by a mobile station a broadcast service from a base station that transmits in the same time period data on a packet data channel and a packet data control channel corresponding to the packet data channel. In the method, the mobile station receives a broadcast service parameter message including parameters for a broadcast service, and transmits desired broadcasting data along with a packet data channel assignment request message based on the parameters. Further, the mobile station receives a packet data channel assignment message for the desired broadcast service in response to the packet data channel assignment request message. Thereafter, the mobile station decodes reception data on a packet data control channel corresponding to the assigned packet data channel to acquire control information, receives packet data on a packet data channel for the broadcast service according to the control information, and processes the received packet data as broadcast service data.
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 reverse transmission controlling method in a mobile communication system, after receiving forward information, commanding the increase or decrease of the reverse data rate received on a forward control channel from a base station, a mobile station determines whether the previous rate increase available information transmitted to the base station on a reverse control channel before reception of the forward information indicates that a reverse data rate increase is available, if the forward information commands a reverse data rate increase. The mobile station increases the current reverse data rate to a data rate equal to or less than a maximum reverse data rate if the rate increase available information indicates that the reverse data rate increase is available, and transmits reverse data at the increased reverse data rate.

摘要:
A method and apparatus are provided for receiving, by an access network (AN), reception strength of a forward pilot channel, measured and reported by each access terminal (AT), as forward data rate information, and transmitting packet data to each AT according to the forward data rate information. When the number of repeated transmission slots for packet data transmitted based on the forward data rate information is greater than or equal to two, the AN repeatedly transmits the packet data as many times as the number of slots, which is less than the number of repeated transmission slots, and transmits new packet data through the remaining slots.
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.
