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： Disclosed is a method in a base station for providing a network access service to terminals. Where one of the terminals is selected as a source terminal and at least one of the other terminals is used as a relay node for relaying communication between the base station and the source terminal. Parameters for relay communication are initialized. A relay communication request message including that the parameters is transmitted. In response to the message, a terminal independently sets and performs the relay communication between the base station and the source terminal. Uplink signals are received from the source and relay terminals. The uplink signals received from the source and relay terminals are combined and decoded. A transmit diversity gain is obtained in uplink transmission of a terminal with a single antenna because relay nodes retransmit the source terminal's signal.

摘要： In a resource allocation method in a multicarrier-based mobile communication system that includes base stations and supports multiple access of a plurality of terminals identified using codes, the service area of each base station is divided into at least two virtual cells having different radii about the base station, and resources are actively allocated to terminals located in the service area according to distribution of the terminals in the virtual cells. The service area is divided into two virtual cells based on the received signal strengths of the terminals for a specific subchannel, and the specific subchannel is allocated to one terminal or at most two terminals according to distribution of the terminals in the virtual cells.

摘要： A resource allocation scheduling method for a cellular communication system that can avoid interference between cells. The method includes dividing a frequency band of a system into frames each having preferential allocation blocks and general allocation blocks on a time axis, classifying terminals in each cell into groups of terminals vulnerable to interference and terminals non-vulnerable to interference, and allocating resources by terminal groups according to priority orders given to the terminal groups. The preferential allocation resources designed to have the orthogonality to the interference cells, i.e., sectors, on the time axis are allocated to the terminals vulnerable to the interference, and the remaining resources are allocated to the terminals non-vulnerable to the interference.
