Method and system for controlling power of common channel

Abstract

The invention discloses a method and a system for controlling power of a common channel. The method comprises the following steps that: if user equipment determines that the quality of a current wireless coverage cannot meet a requirement, a communication request signal is transmitted to system equipment; and an access entity of the system equipment controls the transmitting power of the common channel according to the received communication request signal. By adopting the technical scheme, the transmitting power of the common channel can be reasonably controlled according to the actual need of the user equipment; the energy consumption of the whole wireless communication network is reduced, and the radio frequency pollution and the radio frequency interference of the whole network coverage area are reduced; and the interference between the access entities can be reduced and the system gain is obtained.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a common channel power control method and system. Background technique [0002] Currently widely used wireless communication systems include: GSM (Global System for Mobile Communications, Global System for Mobile Communications), WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access), CDMA2000, TD-SCDMA (Time Division-Synchronous Code Division Multiple Access , Time Division Synchronous Code Division Multiple Access), WIMAX (Worldwide Interoperability for Microwave Access), LTE (Long Term Evolution, long-term evolution), WLAN (Wireless Local Area Networks, wireless local area network), etc., in these wireless communications System composition, generally can be divided into two parts: user equipment and system equipment. User Equipment (UE for short) may be a mobile phone, a computer, a data card, etc., and is also called a ...

Problems solved by technology

In fact, in many cases, the user equipment in the cell does not need such a large common channel power. For example, at this time, there is no user equipment in the cell 1 for communication, so there is no need to transmit such a large common channel power all the time, resulting in waste of energy. At the same time, it also causes radio frequency pollution to the environment

[0005] To sum up, the power consumption of the wireless transmitter of the current system equipment occupies a large proportion of the power consumption of the entire network
