Abstract  Abstract

A method for service option of CDMA wireless communication covering technology in the technology by the code with different phases of a given long pseudo-noise (PN) code is assigned to each sub-channel on the reverse link defined sub multiple can be allocated. Then deciding not to assigning subchannels according to need by dynamically allocating a sub-channel or distributing multiple sub-channels to meet the instantaneous bandwidth requirements of each online user unit connected to each network layer. the system effectively provide comparing amount of virtual physical connection between the subscriber unit and the base station on the reverse link in the idle period has been extended (e.g. power supply unit is connected with the user computer but not presently actively sending or receiving data). the maintaining channel allows the base station and user unit maintains synchronization of the phase and time. This in turn allows fast obtains additional when it is needed by allocating new code phase subchannels subchannels. Preferably the code phases of the new channel is relative to the corresponding maintenance sub-channel code phase of a predetermined code phase relationship specified.

A service option overlay for a CDMA wireless communication in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a given long pseudonoise (PN) code to each subchannel. The instantaneous bandwidth needs of each on-line subscriber unit are then met by dynamically allocating none one or multiple subchannels on an as needed basis for each network layer connection. The system efficiently provides a relatively large number of virtual physical connections between the subscriber units and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber units are powered on but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase and time synchronism. This in turn allows fast acquisition of additional subchannels as needed by allocating new code phase subchannels. Preferably the code phases of the new channels are assigned according to a predetermined code phase relationship with respect to the code phase of the corresponding maintenance subchannel.
