Power control method in communication method and its system

Abstract

The invention relates to a power control method in communication system, wherein it comprises that: obtaining the error code rate of data speed control channel and the error pack rate of reverse service channel; comparing said error code rate, error pack rate, and target error code rate and error pack rate, while any one of target rates is higher, improving the power control threshold value; based on said threshold value, processing inner loop power control. The invention adjusts the access terminal emission power, to confirm the quality of DRC channel; therefore, the service area can install relative data pack via the speed requested by access terminal, to hold high forward chain throughout.

Description

technical field [0001] The present invention relates to a communication method and system thereof, in particular to a power control method and system thereof in the communication system. Background technique [0002] Referring to Fig. 1, in CDMA2000 1x EVDO technology, AT (Access Terminal, access terminal) 100 sends rate request to AN (Access Net, access network) 200 in real time through reverse channel, AN 200 according to the rate of AT 100 request And the forward scheduling policy determines the forward data packet format. The AT 100 decides which sector in the AN 200 to request data according to the wireless environment and the PER (Packet Error Ratio) of the forward data packet. AT 100 then sends the sector ID and rate ID to AN 200 through a DRC (Data Rate Control, data rate control, including sector ID and rate ID) channel. [0003] The sector selected by the AT 100 is called the serving sector, and this sector is generally the sector with the best forward link among...
