Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Fig. 1 is the flow chart of the method measured according to the control subscriber equipment of the embodiment of the invention.As shown in Figure 1, this method comprises:
Step S102, RNC notice UE carries out ANR and measures, and the measurement and report parameter is indicated to this UE, and wherein, the measurement and report parameter comprises: thresholding that preset duration, ANR measure and the sub-district maximum quantity that reports;
Step S104; UE carries out ANR and measures, and will satisfy preset relation with the thresholding that ANR measures and (can confirm according to actual conditions, for example; Greater than or more than or equal to) measurement result carry out periodic report according to this preset duration; Wherein, report the measurement result of M sub-district, M is not more than this sub-district maximum quantity that reports at every turn.
Through above method; UE can carry out ANR and measure under the control of RNC, and, the measurement and report mode that RNC can also indicate UE to adopt as a result the time at reporting measurement; Thereby, report mode to come the real-time and the accuracy of control survey information through adjustment according to the demand of self.In the method; Report the length (above preset duration) of the indication of mode through the cycle, the thresholding that ANR measures, the sub-district maximum number that reports is come common expression; Wherein, The length in cycle representes that the interval of UE reporting measurement reports can not be less than the length in cycle, and the thresholding that ANR measures representes that UE carries out measured value needs and this thresholding that ANR measures and satisfies certain relation, and the sub-district maximum number that reports representes that the measurement report that UE reports at every turn can not surpass this value.The sub-district maximum quantity that RNC can report through control prevents that the sub-district that once reports is too much, and UE that causes and the OL problem of the processing of RNC also can be simplified RNC carries out follow-up judgement or processing according to measurement result complexity to a certain extent; And, the minimum period that RNC reports through control, can prevent too frequent measurement and report; In addition; The thresholding that RNC measures through control ANR; Can control the condition that satisfy the sub-district that reports; Just have only the corresponding measurement result in sub-district that satisfies specified conditions to be reported, for the performance of optimization system can make these specified conditions be the definite significant sub-district for switch decision or neighbor cell configuration renewal.
In practical application; RNC can adopt the mode that is used to notify UE to carry out the notification message of ANR measurement to the UE transmission to notify UE to carry out ANR measurement, the relevant parameter when coming notifying user equipment to carry out the ANR measurement and report through the mode of in notification message, carrying the measurement and report parameter.This reports parameter to change according to condition of different, thereby has improved compatibility and application flexibility.
Particularly, measurement and report parameter the mode to UE of indicating can be included but not limited to one of following:
(1) three cells of configuration in notification message, the preset duration of expression, the thresholding of ANR measurement, the sub-district maximum quantity that reports respectively.
(2) the sub-district maximum quantity that reports that RNC and UE consult is adopted in indication, that is, define a grand value and represent the sub-district maximum number that reports, and two cells of configuration in notification message carry the thresholding of presetting duration and ANR measurement respectively.
Preferably; In notification message, can also carry physical quantity to be measured; The thresholding that the thresholding that the ANR that then comprises in the measurement and report parameter measures is measured for the ANR corresponding to this physical quantity to be measured; Wherein, This physical quantity can include but not limited to following one of at least: ratio (the Common Pilot Channel Energy per chip Noise Ratio of CPICH Common Pilot Channel chip energy and band limited white noise power spectral density; Abbreviate CPICH Ec/N0 as), CPICH Common Pilot Channel received signal code power (Common Pilot Channel Received Signal Code Power; Abbreviate CPICH RSCP as), Primary Common Control Physical Channel received signal code power (Primary Common Control Physical Channel Received Signal Code Power; Abbreviate Primary CCPCH RSCP as), time slot signal sign indicating number power disturbance path loss (Timeslot Interference on Signal Code Power Pathloss abbreviates Timeslot ISCP Pathloss as).Be employed in ANR and measure the way of carrying physical quantity to be measured in the notification message, which physical quantity indication UE that can be real-time measures, make to measure to have more specific aim, on using flexibility higher, can increase work efficiency greatly.Above-named physical quantity has been reacted the different conditions of sub-district, in the practical implementation process, can choose one or more and measure according to different situations, certainly, also can expand it, chooses more physical quantity and measures.
Need to prove; When RNC notifies physical quantity to be measured to subscriber equipment; The thresholding that the ANR of notice measures can be complementary with this physical quantity to be measured, that is to say, the thresholding that this ANR measures can be the threshold value that reports to this physical quantity to be measured.But, it will be appreciated by those skilled in the art that thresholding that this ANR measures also can be independent of physical quantity to be measured and carry; That is to say; Can only carry the thresholding that this ANR measures, and not indicate physical quantity to be measured, at this moment; The terminal can the employing system physical quantity of regulation measure, compare to satisfy under the pre-conditioned situation with this thresholding in the result who measures again and report.
In notification message, carry after the above information; UE carries out ANR and measures, and the measurement result that will satisfy preset relation with the thresholding that ANR measures can comprise according to the process that preset duration carries out periodic report: UE measures the physical quantity to be measured of carrying in the notification message; UE will be carried in the measurement report with the measurement result that this thresholding of measuring corresponding to the ANR of physical quantity to be measured satisfies preset relation; Carry out periodic report according to preset duration; This step is equivalent to UE and carries out the judgement whether report condition satisfies, when satisfying report condition to the radio network controller reporting measurement reports.The process of wherein, carrying out periodic report according to preset duration can comprise:
