The method includes the steps of checking whether a limitation for a reverse autonomous rate of an MS is persistent when it is determined from a reverse load that the limitation for the reverse autonomous rate of the MS is necessary, and transmitting information for limiting the reverse autonomous rate of the MS and information indicating persistence of the limitation for the reverse autonomous rate to the MS when it is necessary to persistently maintain the limitation for the reverse autonomous rate of the MS.

Abstract: A method for providing an interactive data service between a base station and a mobile station in a mobile communication system including at least one mobile station, the base station communicating with the mobile station, and a server connected to the base station. The base station simultaneously transmits data transmitted from the server, to one or more mobile stations over a forward common channel. A particular mobile station receiving a service through the common channel transmits reverse transmission data over a dedicated channel.

Abstract: 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.

Abstract: A system is provided that provides a voice call service over a Circuit Switching (CS) domain to a User Equipment (UE) that was receiving a service in a Packet Switching (PS) domain. A Mobile Management Entity (MME) sends a paging message to the UE to provide a service in the CS domain. The MME sends a suspend request message requesting suspension of the service being provided to the UE in the PS domain, upon receiving a report message indicating that the UE has switched to the CS domain. A gateway suspends the service in the PS domain upon receiving the suspend request message from the MME.

To activate one of a plurality of packet data services in the dormant state, a BS transmits to an MS a Page Message containing an SR ID identifying the service to be activated. If a service instance for the service is unavailable, the MS transmits to the BS a response message indicating that the service cannot be reconnected. The BS then terminates immediately, thereby saving radio resources and improving system performance.

Abstract: A system is provided for managing mobility of an Access Terminal (AT) in a Proxy Mobile Internet Protocol (PMIP) communication system. As the AT performs a handoff, a target Signaling Radio Network Controller (SRNC) delivers session information of the AT, acquired from a source SRNC of a source network, to a target Access Network (AN). An Authentication, Authorization and Accounting server (AAA) performs an AT access authentication process. Then, a target Access Gateway (AGW) performs a proxy registration procedure, with the target AN, and receives, from the AT, a message indicating a need to establish an interface with the HA. A Home Agent (HA) performs mobility management for the AT, receives a message for requesting proxy registration for mobility management for the AT, sends an access request message to the AAA, receives an access accept message, and sends a response message for proxy registration to the target AGW.

Abstract: A method and apparatus for performing device authentication and user authentication in a mobile communication network are provided. A connection is established between an MS and an SRNC that controls communications of the MS through a BS. The SRNC receives a D-MSK for device authentication of the MS from an AAA server that has completed an EAP negotiation with the MS and stores the D-MSK by the SRNC, when the BS triggers an EAP authentication after the connection establishment. The SRNC receives an R-MSK from an AG and stores the R-MSK after the connection establishment. The R-MSK is generated using a U-MSK for user authentication of the MS received from the AAA server by the AG. The SRNC generates a PMK for use during a session using at least one of the D-MSK and the R-MSK, and one of the BS and the SRNC generate a key set using the PMK, for use in at least one of data encryption, data integrity check, and session management during the session.

Abstract: A method and system for performing handoff between a source system and a target system are provided. The target system has a different network access standard from that of the source system. An access terminal, connected to the source system, transmits a request message including an identifier of the access terminal to be identified in the target system, to the target system, via the source system, in order to access the target system. A session storage of the target system acquires the identifier of the access terminal from the access terminal via the source system. The session storage of the target system acquires session information of the access terminal from an old session storage to which the access terminal was connected before it accesses the source system, using the acquired identifier. After the session information is acquired, a gateway of the target system acquires context information related to a data service of the access terminal from a gateway of the source system.

Abstract: 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.
