摘要： A base station includes an adjacent cell interference amount calculator and an adjacent cell interference amount notifier. The adjacent cell interference amount calculator calculates an adjacent cell interference amount caused by an adjacent cell adjacent to an original cell managed by the base station. The adjacent cell interference amount notifier notifies the mobile station of the adjacent cell interference amount. A mobile station includes radio resource associators, a selector, a propagation loss calculator, and a radio resource assigner. The radio resource associators associate a radio resource with a propagation loss in the radio packet communication. The selector selects a radio resource associator in accordance with the adjacent cell interference amount. The propagation loss calculator calculates a propagation loss in the radio packet communication. The radio resource assigner assigns the radio resource associated with the calculated propagation loss to the radio packet communication, based on the selected radio resource associator.

摘要： One preferred embodiment of the invention provides a wireless base station which provides a multicasting service to simultaneously transmit identical data to a plurality of wireless terminals. A wireless base station is connected to a plurality of wireless terminals and provides a multicasting service for a plurality of wireless terminals. The wireless base station determines autonomously whether it provides the multicasting service for the plurality of wireless terminals. Another preferred embodiment of the invention provides a method of selecting a wireless base station for a wireless terminal, the wireless base station providing a multicasting service for the wireless terminal. When the wireless terminal can receive the same multicasting information from a plurality of wireless base stations, the wireless terminal selects one of the plurality of wireless base stations so as to make the number of the wireless base stations that send the same multicasting information as small as possible.

摘要： An object of the invention is to make improvement in the configuration of location registration areas. When a base station 13P is newly installed in a location registration area 30A, the base station 13P recognizes a location of its own with GPS or the like and performs communication with a plurality of surrounding base stations 13Q to select a location registration area 30A to which it should belong, based on the belonging status of the surrounding base stations 13Q and the location of its own. If the base station 13P is located near a boundary between location registration areas and if the surrounding base stations 13Q belong to a plurality of location registration areas, the location registration area to which the base station 13P should belong may be selected so as to average traffics in the respective location registration areas, or the location registration area with the smallest number of base stations belonging thereto may be selected so as to average the numbers of base stations in the respective location registration areas. The base station 13P broadcasts an area identifier of its belonging location registration area 30A to mobile stations under control thereof and starts provision of service thereto.

摘要： The mobile station visiting a location registration area at the present time plans to move to another location registration area at a future time. The mobile station sends the moving schedule information to the location management agent in a prescribed format to notify it of the scheduled destination. Receiving the moving schedule information, the location management agent learns the location registration area corresponding to the scheduled destination among the plurality of location registration areas. The location management agent sets a moving schedule flag in the location registration database in accordance with the moving schedule information with that format, which is received from the mobile station, and makes an additional registration of the moving time and the destination location registration area. Then, at the future time, it updates the location registration database, thereby making a new location registration.

摘要： In mobile communication system 100 according to the present invention, mobile station 1 is camped on cell C10 established by base station B10. In the cell C10, there exist indoor cells C11-C13 and outdoor cells C21, C22 as neighboring cells. Mobile station 1 measures received levels of cells C10-C13, C21, C22 and determines cell types of the respective cells, i.e., whether each cell is an indoor cell or not, based on broadcast information M1. Mobile station 1 selects a cell as a reselection target on the basis of the received levels and cell types.

摘要： A mobile communication scheme realizing highly reliable handover and improved service quality. The communication signals containing identical communication data are transmitted simultaneously from the mobile station to more than one base stations at a time of the handover, such that reception signals are composed from the communication signals received by more than one base stations by using the reliability information for the received communication signals. For the packet communication, the identification information for identifying each packet is attached to each packet, and the reliability information for each packet is measured, such that the reception packets can be obtained according to the identification information attached to each packet and the reliability information measured for each packet.
