Embodiment
Below in conjunction with the accompanying drawing in the present embodiment, be clearly and completely described the technical scheme in the present embodiment, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiments provide a kind of report method of cell measurement results, the executive agent of this method is subscriber equipment, and as shown in Figure 1, the method comprises:
101: receive the measurement configuration messages that base station sends, described measurement configuration messages comprises cell list to be measured, and described community to be measured comprises the adjacent cell of current service cell and the first quantity.
Wherein, in this step indication cell list to be measured in preserve the mark of each community to be measured.
In this step, the measurement result reporting schemes of indication is used to indicate subscriber equipment to the mode adopted during the report measurement results of base station and type, the reporting schemes such as periodically reported or the reporting schemes of reporting events, if the reporting schemes of reporting events, then the event type etc. adopted.
In this step, the current service cell of indication is the current persistent district of described subscriber equipment.
In the implementation of this step, base station connects reconfiguration message by wireless heterogeneous networks (RadioResourceControl, RRC) and measurement configuration messages is sent to subscriber equipment.The described measurement configuration messages that subscriber equipment issues according to base station is measured Serving cell and adjacent cell, and to base station send RRC connect reshuffled message represent measure configuration complete.
It should be noted that, in the present invention, the measurement of indication comprises common frequency measurement, different-frequency measure and isosystem measurement etc.
102: according to described measurement configuration messages, current service cell is measured, determine the measurement result that described current service cell is corresponding.
Wherein, the signal quality parameter of indication can be Reference Signal Received Power (ReferenceSignalReceivingPower, RSRP), also can be the value of Reference Signal Received Quality (ReferenceSignalReceivingQuality, RSRQ).
In the implementation of this step, subscriber equipment is after the RRCConnectionReconfiguration message receiving base station transmission, just start to measure Serving cell, and then obtain the value of signal quality parameter of current service cell, again based on the value of this signal quality parameter, determine final measurement result.
103: if measurement result corresponding to described current service cell is less than first threshold, then each adjacent cell is measured, determine the measurement result that each described adjacent cell is corresponding.
When the measurement result of Serving cell is greater than first threshold, show that the service quality of current service cell is better, without the need to switching cell, thus need not measure adjacent cell, continue to measure current service cell and adjacent cell according to normal measurement procedure.
When the measurement result of Serving cell is less than first threshold, shows that the service quality of current service cell is poor, may switching cell be needed, thus needing the adjacent cell all to be measured to measuring indication in configuration messages to measure.
104: if the measurement result of described current service cell is also less than Second Threshold, and the measurement result that there is the adjacent cell of the second quantity is greater than the measurement result of described current service cell, then report the measurement result of the adjacent cell of described second quantity, described first threshold is greater than described Second Threshold.
Wherein, first threshold is greater than Second Threshold, and the first quantity is greater than the second quantity.
When the measurement result of current service cell is less than first threshold, after each adjacent cell is measured, obtain the measurement result of each adjacent cell, then also need the measurement result of current service cell and the measurement result of each adjacent cell and Second Threshold to compare, and determine whether to need report measurement results according to comparative result.Specifically, the comparative result obtained is as follows with the corresponding relation whether reported:
When current service cell measurement result and adjacent cell measurement result are all greater than Second Threshold, although illustrate that subscriber equipment is in cell edge, but signal quality is relative better with disturbed condition be subject to etc., thus do not need to reporting subdistrict, base station measurement result, continue to measure current service cell and adjacent cell according to measurement procedure.
When current service cell measurement result and adjacent cell measurement result are all less than Second Threshold, illustrate that subscriber equipment is in cell edge and signal quality is relative with the disturbed condition be subject to poor, now, need the measurement result of current service cell and the measurement result of adjacent cell to compare; If the measurement result of current service cell is greater than the measurement result of adjacent cell, illustrate that current service cell network environment is better for adjacent cell, equally without the need to reporting; If current service cell measurement result is less than the measurement result of adjacent cell, illustrate that subscriber equipment can be switched to adjacent cell, thus need adjacent cell measurement result to report base station.
When current service cell, measurement result is less than Second Threshold, but when adjacent cell measurement result is greater than Second Threshold, the measurement result of adjacent cell is reported as base station; Otherwise the measurement result when current service cell is greater than Second Threshold, and when adjacent cell measurement result is less than Second Threshold, then without the need to report measurement results.
In sum, only have the measurement result when current service cell to be less than Second Threshold, and there is one or more adjacent cell, when its measurement result is greater than the measurement result of current service cell, just need to base station report measurement results.Also namely report in process what carry out cell measurement results, after the measurement result of subscriber equipment to each community compares, the measurement result of the adjacent cell satisfied condition by comparative result reports to base station.
In the specific implementation process of this step, after subscriber equipment completes measurement, when needs report measurement results, measurement result to be inserted in measurement report (MeasurementReport) message and to issue base station; If do not need report measurement results, then do not need to send this measurement report message.
The report method of the cell measurement results that the embodiment of the present invention provides, first current service cell is measured, obtain the measurement result of current service cell, and when this measurement result is less than first threshold, carry out the measurement of adjacent cell again, the measurement result when current service cell is only had to be less than Second Threshold, and there is measurement result when being greater than the adjacent cell of the measurement result of current service cell, report the measurement result of these adjacent cells again, with prior art, as long as the measurement result of current service cell is less than certain threshold value, then carry out reporting of cell measurement results to compare, what the present invention can reduce cell measurement results reports frequency, and then reduce because of the signaling consumption shared by frequent report measurement results.
Supplementing as method shown in Fig. 1, the described measurement configuration messages that subscriber equipment receives also comprises the loss parameter of each community to be measured and the value of interference parameter.Wherein, the value of loss parameter mainly comprises the summation of the value of the various losses such as path loss, penetration loss, human body loss, base station line loss, for showing the waste introduced by communication environments between subscriber equipment and base station; In this step, the value of the interference parameter of indication is the value that each community to be measured is subject to the interference of other communities, represents by interfering signal power.The value of these two parameters is calculated by base station and is handed down to subscriber equipment.In the specific implementation process then " according to described measurement configuration messages, current service cell measured, determine the measurement result that described current service cell is corresponding " in step 102, as shown in Figure 2, comprising:
201: according to described measurement configuration messages, current service cell is measured, obtain the value of the signal quality parameter of described current service cell.
202: according to the value of signal quality parameter corresponding to described current service cell, loss parameter and the value of interference parameter and the value of default bias parameter and lag parameter, determine the measurement result that described current service cell is corresponding.
