102: what receive that UE reports in the given time is satisfied when measuring the measurement report required, UE to switch according to the content of described measurement report or is redirected to Target cell by base station.
In LTE communication system, each E-RAB(Evolved-Radio Access Bearer of built Data Radio Bearer can be preserved in UE context, evolved wireless access bearer) information, situation can be set up to judge whether this UE exists business with the E-RAB of UE in base station, such as: when the E-RAB of UE sets up, judge that UE exists business.
Measurement request in step 101 can be included in RRC Connection Reconfiguration(RRC and connect reprovision) in message, also can send as an independent message, measurement request comprises measurement configuration information; UE measures adjacent cell according to the measurement configuration information in the request of measuring.Of the present invention is in embodiment, measurement configuration information comprises adjacent cell quality threshold, the content measured comprises adjacent cell quality information, as: Reference Signal Received Power (RSRP, Reference Singnal Received Power), Reference Signal Received Quality (RSRQ, Reference Singnal Received Quanity) etc.; UE perform measure and when meeting measuring condition report measurement results to base station.Concrete, can be the A4 event that specifies in 3GPP communication protocol to trigger reporting measurement reports, namely when adjacent cell quality is higher than setting thresholding, namely think to meet and measure requirement, by measurement report message, measurement result is sent to base station.UE is switched to this community by the satisfied community ID measuring the adjacent cell required that base station is carried according to measurement report.When measurement report carry satisfied measure the community ID of adjacent cell required have multiple time, UE can be switched or be redirected to the best community of cell quality, or the community that the high frequency of priority is corresponding; The Target cell that also can switch according to other rules selections or be redirected.
As shown in Figure 2, community A will carry out deleting building, and the base station at A place, community is designated as base station A.The method of UE call drop is avoided to comprise in the present embodiment:
Step 201: base station A opens a timer after receiving the instruction wanting shutting off cells A, and issue A4 measurement request successively according to certain time interval T to the UE that there is business in the A of community;
Concrete, this A4 measures request and can be included in RRC Connection Reconfiguration message, also can send as an independent message.
Step 202: after the UE that there is business in the A of community receives A4 measurement request, carry out A4 measurement, when satisfied measurement requires, reporting measurement reports is to base station A before timer expiry; Measure requirement when UE does not meet, or do not report A4 measurement report before timer expiry, then jump to step 204.
The physical label meeting and measure the community required is carried in described measurement report; For convenience of describing, suppose that the community that in the measurement report that UE1 reports, satisfied measurement requires is community B here.
Step 203: base station A switches UE1 or is redirected to Target cell B.
Switch and be redirected the content all belonging to prior art, repeating no more.If meet measure require adjacent cell have multiple, base station A can UE1 switch or be redirected to the best community of cell quality.
Step 204: UE is redirected to the high community of priority according to neighbor cell configuration information and predetermined priority by base station.
