Embodiment Construction

[0032] The present invention aims at the characteristic that the non-linear superposition of forward supplementary channel transmit power in the CDMA cellular cluster communication system that shares the forward traffic channel in the prior art may make the shared transmit power control of the forward supplementary channel relatively large and even overload the forward power. , a method is proposed to realize the power overload control of trunking group forward supplementary channel in CDMA cellular trunking communication system, and to control the forward supplementary channel sharing transmission power of trunking group users in digital trunking communication system within an appropriate range.

[0033] figure 1 It is a flow chart of the steps of the method of the present invention, and the method comprises the following steps:

[0034] Step 201: Determine the maximum power that a group of users in a sector can achieve when sharing the forward supplementary channel.

Abstract

A method for controlling power overload of shared forward complementary channel includes confirming maximum power being allowed to reach of shared forward complementary channel, decreasing actual power of shared forward complementary channel to be said maximum power by decreasing power of one or multiple forward complementary channel with power being greater than average power when actual power ofsaid shared forward complementary channel is greater than said maximum power.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for controlling power overload of a group sharing forward supplementary channel in a code division multiple access mobile communication system supporting trunking services. Background technique [0002] The trunking communication system refers to a dedicated mobile communication system in which multiple users share a group of wireless channels and use these channels dynamically. It is a command and dispatch system. The cellular trunking communication system combines the cellular communication system with the dedicated dispatching communication system, which not only expands the business scope of the cellular communication system, but also frees the trunking communication system from the functional and regional limitations of the dedicated dispatching communication system. The combination of CDMA (Code Division Multiple Access) cellular communication system and digital...
