The speed of A, B and c service is taked the dynamic rate method of adjustment based on transport service, corresponding given respectively speed grade, the speed of A service is submitted to the base station in the lump according to concrete business during by the mobile radio station submit applications, the speed of b service is minimum, can be used as minimum reserved bandwidth, the summary height of c service speed ratio B wraps in link layer with the reply data that guarantees TCP and does not postpone just can send.
The speed of d service is taked the Real-time Channel distribution method based on packet, be after A, B and c service are finished the speed adjustment, remaining total bandwidth is as the bandwidth of d service, basic distribution method is a poll, mobile radio station of every poll just distributes a code channel, if this mobile radio station the code channel number that obtains greater than its packet number, then stop to be this mobile radio station poll; If the packet of all mobile radio stations has all obtained code channel, perhaps not remained code channel can distribute, and then whole allocation process finishes.
Dynamic rate is adjusted the result and is converted to the code channel number a that mobile radio station can send, together with the Real-time Channel allocation units is the number of channel b that mobile radio station distributes, forming speed indication information announces to mobile radio station, the up total code channel number that sends of next time slot of mobile radio station is a+b, if mobile radio station is not received speed indication information, then the speed grade of receiving according to the last time (being a value) sends upstream data.
Allocated bandwidth of the present invention takes mobile radio station submit applications, base station to concentrate the control mode of distributing.Allocation strategy uses based on the dynamic rate adjustment of transport service with based on the Real-time Channel of packet and distributes two kinds of means to combine.This method not only can be avoided because the upstream data amount surpasses the data collision that up-link capacity causes, and can reduce the propagation delay time of burst data business, type of service is segmented, take different rate adjusting methods to dissimilar, utilize upstream bandwidth to the full extent, guaranteed the fairness between mobile radio station simultaneously again.
