Embodiment
Main design of the present invention is, in the prior art, triggers the measuring amount that UE reports and has only one, promptly or be RSRP, or is RSRQ.Wherein, when the measuring amount of eNB configure trigger measurement is RSRP, when the measurement result that UE measures satisfies this measuring amount threshold requirement and has reported the measurement report relevant with handover event, the judgement that the incident of this measurement report correspondence that eNB reports according to UE is switched is also initiated switching flow, but may cause the reduction of quality of handoff and increase cutting off rate.Reason is as follows: though RSRP_A＜RSRPThr_A and RSRP_B＞RSRPThr_B (perhaps RSRP_A+RSRPOffset_AB＜RSRP_B), the Reference Signal Received Power that seems the adjacent area is well more a lot of than Serving cell, satisfy the requirement of switching, but also do not know RSSI_A and RSSI_B this moment, might this moment RSSI_A very little and RSSI_B is very big, thereby cause RSRP_A/RSSI_A＞RSRP_B/RSSI_B, that is: RSRQ_A＞RSRQ_B, that is to say Reference Signal Received Quality obvious Reference Signal Received Quality this moment of Serving cell A this moment greater than adjacent area B, and eNB also will initiate to switch, then will inevitably cause switching the reduction of back speech quality, finally cause call drop, and reduce user's satisfaction.
And when the measuring amount of eNB configure trigger measurement is RSRQ, when the measurement result that UE measures satisfies this measuring amount threshold requirement and has reported the measurement report relevant with handover event, the judgement that the incident of this measurement report correspondence that eNB reports according to UE is switched is also initiated switching flow, also may cause the reduction of quality of handoff and increase cutting off rate.Reason is as follows: though this moment, RSRQ_A＜RSRQThr_A and RSRQ_B＞RSRQThr_B (perhaps RSRQ_A+RSRQOffset_AB＜RSRQ_B), the Reference Signal Received Quality that seems the adjacent area is better than Serving cell, satisfy the requirement of switching, but also do not know RSRP_A this moment, RSSI_A and RSRP_B, the relation of RSSI_B, though might satisfy RSRP_B/RSSI_B＞RSRP_A/RSSI_A this moment, but might be RSRP_B, RSSI_B is respectively much smaller than RSRP_A, RSSI_A and RSRP_B can not satisfy the requirement that signal sent and then guaranteed speech quality at all, and eNB also will initiate to switch, then will inevitably cause switching the reduction of back speech quality, finally cause call drop, and reduce user's satisfaction.
To sum up analyze as can be seen, can only be set to RSRP or RSRQ owing to trigger measuring amount in the existing measurement configuration, UE is for judging and trigger according to the dependency relation of set triggering measuring amount with only reporting also of the measurement report that switches relevant measurement event correspondence, thereby that may cause that UE can report and be not suitable for switching with switch relevant measurement newspaper message and cause eNB and the situation of improper initiation switching under initiated switching flow, and then the reduction that causes UE to switch back speech quality, and increase cutting off rate and reduce customer satisfaction system problem.
Therefore the present invention proposes, increasing triggering measurement value in measuring configuration is the option of RSRP and RSRQ, like this, in the time of in measuring configuration, will triggering measuring amount and extend this as RSRP and RSRQ, UE is in measuring process, to comprehensively judge according to the RSRP and the RSRQ that measure whether send the relevant measurement report of handover event to eNB with decision.
