FAST ACQUISITION OF TRAFFIC CHANNEL FOR OBTAINING HIGHLY VARIABLE DATA TRANSFER RATE

摘要

PROBLEM TO BE SOLVED: To fast acquire additional subchannels as needed by allocating new code phase subchannels. SOLUTION: The invention relates to 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 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. COPYRIGHT: (C)2010,JPO&INPIT
