摘要： Disclosed is a mobile communication system including a network constituted of at least one switching center and a plurality of base stations, and a mobile station which communicates with the base stations simultaneously. The system permits varying transmission delay between the switching center and the base stations according to the type of services available to the mobile station. The object of the present invention is to propose a communication which permits varying transmission delay according to the type of service currently employed, and to promptly recover a synchronization state even if an out-of-sync state happens. To attain the object, a memory means (mobile switching center processor 32) stores transmission delay characteristics corresponding to services which are available to the mobile station. Furthermore, a communication timing setting means (diversity handover trunk 34) determines the timing of communication for the base stations according to the transmission delay characteristic selected according to the service.

摘要： A multiplex system for multiplexing packets into ATM cells to be transmitted, which can implement effective use of channels corresponding to irregular traffic qualities in services with various types of quality conditions in an actual environment. In response to a connection establishment request (S402), current required bandwidths B1, . . . , Bm are changed to B′1, . . . , B′m by adding the new connection, which causes bandwidths X1, . . . , Xm which are assigned to the channels to be changed. When the desired bandwidth including the requested connection is less than an available bandwidth of the corresponding channel, an assigned bandwidth change processing (S406) is activated to assign new bandwidths in accordance with desired bandwidths. The bandwidth assignment change is carried out by changing ratios of extraction rates of packets from the buffers in the multiplex system.

摘要： A spreading and/or despreading mechanism in which the inphase component and a quadrature component of a signal are to be transmitted by using a short code and a long code. The long code has an inphase component and a quadrature component that are different from each other. The spreading and despreading operations carry out a complex-to-complex operation between a combination of the inphase component and the quadrature component of the signal and a combination of the inphase component and the quadrature component of the long code.
