Abstract

The invention provides a system for power control according to service quality, which includes a network side device and a terminal. The invention is characterized in that the network side device includes a broadcast unit and an adjustment unit, and the terminal includes a measuring unit and a report unit, wherein: the broadcast unit is used to broadcast quality measuring information on communities' system broadcast information or multimedia broadcast / multicast public control channel; the measuring unit is used to carry out quality measurement on the basis of public transmission channel indicated in quality measuring information; the report unit is used to monitor conditions for the report of quality measurement at user terminal, namely periodical reports or event reports. Users send quality information reports to the wireless network controller according to report rules in quality measurement information; the adjustment unit makes dynamic adjustment to the power of public physical channels according to quality information reported by users.

Description

technical field [0001] The invention relates to a power control system of a wireless cellular communication system, in particular to a system for power control in a wideband code division multiple access WCDMA mobile communication system based on the quality of service of multimedia broadcast and multicast services. Background technique [0002] Multimedia Broadcast / Multicast Service MBMS (Multimedia Broadcast / Multicast Service) is a technology that shares network resources and transmits data from one data source to multiple targets. In the traditional mobile network, the cell broadcast service allows low bit rate data to be sent to all users through the public channel of the cell, and belongs to the message service. In R99, only the short message service belongs to the cell broadcast service. The traditional multicast service allows the mobile subscribers of this service to receive it, but this service does not allow multiple subscribers to share the resources of the wirele...
