Problems solved by technology

[0018] As described above, in the conventional reverse power control method of WLL, since the RP 30 continuously transmits the power control signal to the RIU 20 at predetermined time intervals, a problem occurs that a large amount of power is consumed and the load on the network system is increased

Embodiment Construction

[0029] Refer below Figure 5 with 6 The reverse power control method of the WLL of the present invention will be described.

[0030] When performing reverse power control, first, RP 30 must judge whether there is packet data sent from RIU 20 . The criterion for judging is the power value of the traffic channel. In step S100, by comparing the traffic channel power value sent from the RIU 20 with a preset threshold, it can be known whether there is packet data to be sent.

[0031] At S100, if it is detected that the traffic channel power value is lower than the threshold value, RP 30 judges that there is no packet data sent, and therefore sets a predetermined initial value PT of the correction value PO, and repeats step S100 until the traffic channel detected in S100 The power value becomes greater than the threshold. If it is detected that the traffic channel power value is higher than the threshold, the RP 30 judges that there is packet data transmitted, and thus calculate...

Abstract

A reverse power control method for a WLL is disclosed, in which the number of times of power control value transmission is reduced to 1. The disclosed method complements the related method, in which the power control of a radio interface unit is performed in units of 0.5 dB, so that power is controlled more concretely and flexibly. Unnecessary power consumption due to power control in the WLL system is thus reduced, and the load of the system is reduced, improving the reliability of the communication system.

Description

technical field [0001] The present invention relates to a power control method of a wireless local loop (hereinafter referred to as "WLL"), in particular to a reverse power control method of WLL packet data transmission. Background technique [0002] Conventionally, a WLL system is a system that uses a wireless line to replace a predetermined part of a wired communication line between a conventional switching network or a public switched telephone network (PSTN) and a general subscriber network. Wireless communication technologies applicable to WLL include: a method using artificial satellites, a method using microwaves, a method using cellular technology, a cordless method, and a W-CDMA method. [0003] A conventional WLL power control method will be described below. [0004] figure 1 is a block diagram of a general WLL system architecture. [0005] Such as figure 1 The illustrated WLL system includes: a plurality of user terminals 10 for communication of each user; a p...
