Disclosed is a method for providing a service to MS (Mobile Station) according to a service quality in a service system including MS, BTS (Base Transceiver System) that can communicate with the MS, and a profile server for storing service quality profile information for the MS. The profile server comprises storing identification information indicating a user of the MS along with service quality profiles for the services that can be provided to the MS; and upon receipt of an MS information request from the BTS scheduled to service the MS, providing service quality profiles for the MS to the BTS, and providing a service required by the MS according to a service quality profile for the service.

Method for providing service based on service quality and an accounting method in a mobile communication system

A method and apparatus for supporting a variety of service types in a CDMA2000 1xEV-DO mobile telecommunication system for high-speed data service in a radio communication environment. To receive multiple services according to a plurality of service types, an AT establishes a connection for the data service with a PDSN and configures a session for setting the plurality of service types having different traffic characteristics by the connection. The AT generates a plurality of service instances for the different service types according to the session configuration. It then exchanges data streams with the PDSN in a service instance corresponding to a currently provided service among the plurality of service instances.

Multiple service method and apparatus in a data only mobile telecommunication system

A QoS-based call admission system and method for a mobile communication system. To establish a call for a mobile station according to the QoS of the call, upon request of setup of a call requiring a QoS guarantee, a base transceiver station determines whether a channel element is available. In the presence of an available channel element, the base transceiver station determines whether a remaining bandwidth can support a data rate required to guarantee the QoS. If the data rate is supported, the base transceiver station assigns the channel element and connects its intra switch to a base station controller. Then the base transceiver station transmits a call accept response signal to the base station controller.

System and method for call admission for a mobile communication system

Disclosed is a method for transmitting a packet through a plurality of physical links in a mobile communication system in which a base station controller (BSC) is connected to a base transceiver system (BTS) through the plurality of physical links. The method includes the steps of determining whether a specific service uses at least two links, when there is transmission data for the service; setting up a sequence number in the transmission packet, when the service uses at least two links; and transmitting the packet through a link selected from the two links. The determining step is performed when there is transmission data for the service, and the setting step is performed when the service uses at least two links.

Apparatus and method for multiplexing multiple end-to-end transmission links in a communication system

A base station controller (BSC) performs a handoff of a mobile terminal (MT) moving between cells of base transceiver stations (BTSs) in a mobile communication system. If a target BTS is selected as a handoff candidate for the MT as the MT moves from a cell of a source BTS in service toward a cell of the target BTS, the BSC transmits to the target BTS a first message for requesting the target BTS to buffer packets, and transmits packets to be transmitted to the MT to both the source BTS and the target BTS. If the target BTS is determined as a serving BTS for the MT, the BSC transmits to the target BTS a second message including a last sequence number in order to request the target BTS to transmit, to the MT, packets with sequence numbers following the last sequence number of a last packet transmitted from the source BTS to the MT, among the buffered packets.
