Embodiment Construction

[0022] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The general technical scheme of the present invention is as follows:

[0024] In the present invention, the method for adaptively selecting the uplink transmission power of the mobile phone according to the network signal includes adaptively selecting the uplink transmission power of the control channel (CCH) of the mobile phone in the call establishment phase and adaptively selecting the uplink transmission power of the communication channel (TCH) of the mobile phone in the call phase workflow; such as figure 1 As shown, the specific workflow includes the following aspects:

[0025] Step 101, the mobile terminal has a built-in monitoring control module that automatically adjusts the transmission power, and the mobile terminal is turned on and enters a standby mode;

[0026] Step 102, the mobile terminal enters the cal...

Abstract

The invention discloses a method for improving the quality of the telephone by automatic power control, and is applied in a wireless movable termination of a PHS network; the method comprises: (1) the movable termination is internally provided with a module for monitoring, controlling and automatically regulating transmitted power, and the movable termination is turned on and enters a standby mode; (2) when the movable termination starts to call and is in the stage of call establishment, the module for monitoring, controlling and automatically regulating transmitted power of the movable termination judges the received signal strength indicated value of the network signal, and the transmitted power of a control channel is regulated according to the received signal strength indicated value; (3) when the movable termination enters a conversation stage, the module for monitoring, controlling and automatically regulating transmitted power of the movable termination judges the received signal strength indicated value of the network signal, and the transmitted power of a conversation channel is regulated according to the received signal strength indicated value. By arranging the module for monitoring, controlling and automatically regulating transmitted power in a PHS mobilephone terminal, the method reduces the down-to-earth switching times and drop-call-rate of a base station.

Description

technical field [0001] The present invention relates to the field of wireless communication of PHS low-power communication system (Personal Handyphone System, hereinafter referred to as PHS), and in particular to a method for how to automatically adjust transmission power according to base station signals in a PHS terminal to reduce dropped calls. Background technique [0002] The PHS network is a low-power communication system. Its basic functions are similar to those of the GSM system. It has low radiation to the human body and low cost, but its coverage area is small, the signal coverage is not very good, and it is easy to switch and drop calls during the call. Especially in the edge areas covered by large signal base stations, PHS terminals receive relatively good downlink signals, but the uplink transmission power is relatively weak. In this case, it is easy to cause the base station to switch the mobile phone, and the other party talking with the PHS terminal will expe...
