Description
Technical field
The present invention relates to moving communicating field, in particular to a kind of mobile communication system and signal measurement method, base station and terminal.
Background technology
In mobile communication system, when the signal conditioning of sub-district changed, terminal may need to carry out the sub-district to be switched, and network side can sending measuring control signaling be given terminal usually, thereby starts the process of measuring-signal (for example signal quality or intensity).Measure the target that can comprise measurement in the control signaling, trigger and measure the incident that reports, and the relevant parameter that is used to adjudicate triggering, thresholding for example triggered, the triggered time etc.When terminal finds that when measuring current service cell or adjacent area reach the threshold value of certain incident of triggering, terminal will continue this cell quality of assessment in the triggered time so, if continue to satisfy trigger condition, send measurement report to network so, comprise the incident that is triggered in the measurement report, the sign of measurement result and sub-district.
In the network environment of complexity,, then more help network side and make the mobility decision-making if terminal can report more parameter.So network side can be in measurement configuration information, indicating terminal is measured a plurality of parameters.Because more than one of the parameter that can measure of terminal, only select one usually from being used for the parameter that trigger event reports, also only report this parameter.
Yet in realizing process of the present invention, the inventor finds which parameter triggering measurement reported event network side does not specify by in the prior art, so although terminal possesses the ability of measuring and reporting a plurality of parameters, but because can not select trigger parameter that thereby the triggering report condition is set suitably, so still can not support this many measuring amount to report mode.
For example, the network side measurement configuration information that can issue to terminal is shown in following table one:

……
Parameter n,
},
},
Lag parameter,
Trigger event,
Maximum reporting cell number,
The report interval,
The report sum,
Other parameters, for example report amount etc.
}
When terminal receives above-mentioned configuration information, although known triggering report condition such as lag parameter, can't know but actually which measurement parameter (for example being to signal strength signal intensity or signal quality) is carried out this triggering report condition, so still can not support this many measuring amount to report mode.
