The present invention proposes a kind of broadcast channel coverage self-optimizing method, may further comprise the steps: terminal receives the broadcast channel measurement control order that the base station sends; According to described measurement control order, described terminal is measured the broadcast channel that described base station sends; Described terminal sends measurement result to described base station.
As shown in Figure 1, the flow chart for broadcast channel coverage self-optimizing method end side may further comprise the steps:
Step S101: terminal receives the broadcast channel measurement control order that the base station sends.
In step S101, terminal is obtained the measurement control order of network node indication, according to measurement control order broadcast channel is measured.Usually in mobile communication system, the base station can send broadcast channel in service area, and based on this, the present invention proposes by the base station indicating terminal broadcast channel to be measured.As embodiments of the invention, measurement control order comprises measures content indication, reporting measurement configuration.In the present invention, network node includes but not limited to base station, the O﹠amp in the mobile communications network; M (operation and maintenance, operation and maintenance) these communication device entity of system.
For example, network node selects specific terminal to measure broadcast channel.Preferably, network node selects to be in the terminal measurement broadcast channel of cell edge.Judge whether certain particular terminal is in cell edge, can be accomplished in several ways, receive the power of base station common reference symbol signal as terminal judges self, when finding receiving intensity RSRP (Reference Signal Receive Power, when Reference Signal Received Power) being lower than certain thresholding, can think that self has been in cell edge.
Wherein, reporting measurement configuration comprises and reports content, reports mode and report parameter.Report content to comprise one or more metrical informations of CRC check value of receiving intensity, signal to noise ratio and the broadcast channel of broadcast channel.Report that mode comprises that Event triggered reports, mode such as periodic report or Event triggered periodic report.Report parameter to comprise the threshold value size, trigger the incident that reports or report the time interval etc.
In addition, measure the content indication and comprise multiple metrical information, for example, measure content and can be receiving intensity, signal to noise ratio or the broadcast channel CRC check of broadcast channel one or more metrical informations in whether correct.Network node is the base station for example, the broadcast channel of can indicating terminal measuring Serving cell and/or adjacent sub-district, perhaps measuring the principle that allocating and measuring starts in the control messages, when terminal finds to satisfy the measurement principle according to measurement result, for example be in cell edge, promptly begun to measure corresponding broadcast channel.
Step S102: terminal is measured broadcast channel according to measurement control order.
After the relevant terminal of coincidence measurement condition is obtained measurement control order in step S101,, measure the broadcast channel of Serving cell and/or adjacent sub-district according to measurement control order.Wherein, the content of measurement comprises one or more metrical informations in the CRC check value of receiving intensity, signal to noise ratio and broadcast channel of broadcast channel.
Step S103: terminal sends measurement result to the base station.
According to measurement control order, after measuring, terminal can measurement result be reported according to the selected principle that reports, for example when the CRC of broadcast channel check is wrong, report, report when perhaps the signal to noise ratio of broadcast channel is lower than certain thresholding, report when perhaps the receiving intensity of broadcast channel is lower than certain thresholding.Correspondingly, whether measurement result can correct for the CRC check of the receiving intensity of broadcast channel and/or signal to noise ratio and/or broadcast channel.The principle that reports of terminal can be stipulated by communication system, also can notify terminal by measurement control order by network node.

In addition, when the network node indicating terminal is measured the receiving intensity of cell broadcast service channel and the receiving intensity of adjacent CBCH, when the receiving intensity＞threshold value 1 of cell broadcast service channel and the receiving intensity of adjacent CBCH＞threshold value 2, the measurement result of terminal record corresponding broadcast channel also reports.The receiving intensity that all reports certain broadcast channel within a certain period of time when the terminal that reaches some can think that then this broadcast channel is in strong covering state during greater than predetermined threshold.
Step S202: network node is adjusted the transmitting power of broadcast channel according to statistics.
According to the statistics of step S201, network node for example is base station or O﹠amp; The M system rationally adjusts the transmitting power of broadcast channel.For example, when being weak covering for the broadcast channel of judging Serving cell, network node improves the transmitting power of the broadcast channel of described Serving cell, and when being covering for the broadcast channel of judging certain sub-district of existence, network node reduces the transmitting power of the broadcast channel of sub-district.
