摘要： A system is provided for performing location update in a wireless mobile communication system that uses an Internet protocol (IP) address and is classified as at least one paging group. A serving base station (BS) sends a message including an identifier of a paging group where the serving BS is located, determines whether there is a change in IP subnet of a mobile station (MS) upon receipt of a location update request from the MS, and upon recognizing a change in IP subnet of the MS, stores information on a new IP subnet and notifies the change in the IP subnet to the MS. Upon detecting a need for location update, the MS sends a request for location update to a serving BS, and receives a location update success notification and an allocated temporary IP address from the serving BS.

摘要： A method for determining a handoff of a mobile station (MS) in a mobile communication system. In the method, a serving base station (BS) measures a level of a first uplink signal by monitoring an uplink to the MS. The serving BS receives a level of a second uplink signal, measured and reported by at least one neighbor BS. The serving BS determines a handoff for the MS considering the level of the first uplink signal and the level of the second uplink signal.

摘要： Disclosed is a method for transmitting an uplink data during handoff. A method for transmitting uplink data in a soft handoff system, in which a mobile station is simultaneously connected with at least two base transceiver systems under a control of a base station controller, includes selecting one of the base transceiver systems as a main base transceiver system, transmitting uplink signals to the main base transceiver system and sub-base transceiver systems, and transmitting by the sub-base transceiver systems received uplink signals to the main base transceiver system. Through the method, a main BTS for diversity combining and decoding soft bit strings is established among BTSs connected to a mobile station, so that it is possible to distribute a data processing amount centralized on a BSC to a BTS.

摘要： An uplink resource allocation method is provided for transmitting a control packet on a channel different from a currently connected channel in a wireless communication system for supporting a packet based real-time service. A new format of a grant management subheader is proposed in which a piggyback request conventionally used only for the same connection can be used also for a different connection. A resource allocation request for the different connection can be made using the newly proposed grant management subheader. When the resource allocation request for a new connection is made using the grant management subheader, a resource allocation time can be reduced and loss of resources allocated for an existing connection can be minimized.

摘要： Disclosed is a handoff method connected with resource allocation in order to prevent QoS degradation, which may occur during or before/after a handoff on account of channel state change resulting from the mobility of a radio communication apparatus. To this end, a serving base station currently-connected to the radio communication apparatus and a target base station to be connected after a handoff periodically or non-periodically measure uplink/downlink channel states in relation to the radio communication apparatus, and the target base station allocates resources (e.g., time slot, specific subcarrier, or specific frequency band) most suitable for the service requested from the radio communication apparatus during a handoff, thereby preventing QoS degradation due to the handoff. In addition, in the case of a radio communication apparatus using multiple antennas, the serving base station notifies the target base station of a multi-antenna operation mode in relation to the radio communication apparatus before finishing a handoff procedure, thereby minimizing QoS degradation due to the handoff.
