摘要： Disclosed is a handover method in radio communication. A base station apparatus monitors the receiving state of a terminal, detects, based upon the receiving state, whether the terminal is one in which there is a possibility that loss of a call or a decline in quality will occur or one in which loss of a call or a decline in quality has occurred, and hands over the terminal to another base station apparatus having a carrier frequency different from that of the present base station apparatus.

摘要： A wireless communication system is disclosed that includes plural wireless base stations that act as an origin wireless base station and a destination wireless base station, and a wireless mobile station. The origin wireless base station starts a handover process in response to movement of the wireless mobile station, attaches a header including transfer order information to transmission packet data addressed to the wireless mobile station, and transfers the transmission packet data with the header to the destination wireless base station. The destination wireless base station receives the transmission packet data with the header, determines whether a transfer order of the transmission packet data is correct based on the transfer order information included in the header, deletes the header from the transmission packet data upon determining that the transfer order is correct, and transmits the transmission packet data without the header to the wireless mobile station upon completion of the handover process.

摘要： An interleaving apparatus comprises a first storing unit for storing data to be transmitted and a first control unit for controlling the first storing unit so that the data to be transmitted is outputted from the first storing unit with the data to be transmitted arranged in a matrix and at least either columns or rows of the data to be transmitted randomly rearranged, facilitating the interleaving. The result is that biased distribution of data, which leads to degradation of the transmission quality, can be prevented relatively easily in a simple structure.

摘要： A scheduling process handles a plurality of communication services in a collective manner, thus making a radio communications system more operable. A pilot signal sender sends pilot signals with carrier frequencies each corresponding to an N (N≧1) different communication services. A scheduler collects N×n instances of propagation environment data from n (n≧1) terminal devices and selects terminal devices and communication services therefor by assigning terminal devices having a better propagation environment to the plurality of different communication services in a collective manner. The pilot signals are used by a propagation environment data sender to measure and report a propagation environment of each carrier frequency. A communication function configurer automatically sets up a communication function to adapt to the communication service that the base station has assigned.
