Abstract
The invention provides an autonomous switching and switching processing method of a terminal in a cluster group and an apparatus thereof. The autonomous switching method comprises the following steps that the terminal in a listening state reports a measurement report aiming at a target cell to a network side before autonomous switching, wherein the measurement report carries target cell measurement information used for determining whether the terminal carries out switching; after the terminal reports the measurement report, a source cell is autonomously switched to a target cell. By using the above technical means provided in the invention, technical problems that a base station (the network side) can not acquire autonomous switching of the terminal so that a user experience is poor, frequent autonomous switching causes large air interface configuration information contents and so on in the correlation technology are solved. The network side can participate in the autonomous switching of the terminal so that frequent switching of the terminal and the air interface configuration information contents are reduced and simultaneously the user experience during an autonomous switching process is increased.
Description
Technical field
The present invention relates to the communications field, especially relate to the autonomous switching of terminal in a kind of cluster group, switching handling method and device.
Background technology
Cluster is a system of getting ready to go into action in hundreds, after cluster multi call is set up, if the user being in group's listen state is positioned at cell boarder, when this user detects that abutting subdistrict signal meets autonomous handoff threshold, and Target cell is for this group-calling establishes downlink broadcast carrying, this subscriber equipment (UserEquipment, referred to as UE) is switched to Target cell voluntarily, switches the participation not needing base station.Due to this process base station also and do not know, so some problems can be caused.
In autonomous handoff procedure, dynamic dispatching encounters problems as follows:
As shown in Figure 1, suppose that group calling is at CELL1, CELL2 establishes downlink broadcast carrying, user in CELL1 concentrates on center of housing estate position, CELL1 uses MCS to equal 10 and dispatches, user equipment (UE) 2 in CELL2 is in cell boarder, use MCS (ModulationandCodingScheme, modulation coding mode) equal 4 and dispatch, UE2 moves toward CELL1 side, when meeting autonomous switching condition, UE2 independently switches, after being switched to CELL1, dispatch because the carrying of CELL1 downlink broadcast uses MCS to equal 10, UE2 there will be because MCS difference is too large at CELL1 boundary position, cause cannot correctly receiving downlink broadcast bearing message for some time, UE2 needs by reporting channel quality instruction (ChannelQualityIndicator, referred to as CQI) carry out requirement CELL1 downward MCS, CQI reports general needs 40 milliseconds, two speech frames are had in 40 milliseconds, lower Deng MCS, at least have continuous 3 speech frames frame by mistake, if a terminal frequently switches at boundary position, then there will be sound effect and experience very poor situation, may be poorer for video tastes.
In autonomous handoff procedure, the problem that semi-persistent scheduling runs into:
When MCS changes during semi-persistent scheduling, MCS value can pass through Downlink Control Information (DownlinkControlInformation, referred to as DCI) send once to eating dishes without rice or wine, need up-to-date MCS value to send to abutting subdistrict in real time simultaneously, abutting subdistrict needs to send to terminal in real time by group calling configuration messages, to ensure that group calling listen state user can carry by correct demodulation downlink broadcast in Target cell after autonomous switching, because MCS exists frequent variations situation, sometimes even 100ms changes once, so frequently change can cause adjacent area updating message amount and group calling configuration messages amount of eating dishes without rice or wine huge, affect the disposal ability of base station.For the problems referred to above in correlation technique, there is no solution effectively.
Summary of the invention

Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Fig. 2 is the flow chart of the autonomous changing method of terminal in the cluster group according to the embodiment of the present invention.As shown in Figure 2, the method comprises following treatment step:
Step S202, be in the terminal of listen state before autonomous switching, report the measurement report for Target cell to network side, this measurement report carries for determining that terminal carries out the Target cell metrical information switched;
Step S204, terminal, after reporting above-mentioned measurement report, independently switches to Target cell by cell-of-origin.
By above-mentioned treatment step, because terminal is before autonomous switching, measurement report has been reported to network side, therefore, solve because base station (i.e. network side) cannot know that terminal independently switches the poor user experience caused, and frequently independently switch the technical problems such as configuration information amount is larger of eating dishes without rice or wine caused, thus make network side can participate in the autonomous switching of terminal, decrease the frequent switching of terminal and configuration messages amount of eating dishes without rice or wine, and improve the Consumer's Experience in autonomous handoff procedure.
In a preferred embodiment, network side can show as cell-of-origin, or base station, place, cell-of-origin, or, the common own base station in cell-of-origin and Target cell.

(3) listen user a can directly send measurement report to CELL1 owing to establishing RRC annexation with base station, listening user a to start timer t1 is 80ms;
(4) contain in test report and listen user a, the Target cell CELL2 of autonomous switching, because CELL1 and CELL2 be not at same inside of base station, CELL1 needs the autonomous handover request message sending group A to core net, core net is sent to CELL2 the autonomous switching message of group A, illustrates that CELL1 has and listens user a to be independently switched to CELL2;
(5) CELL2 receives the autonomous handover request message of group A that CELL1 sends, and the scheduling MCS of group A is reduced to 4 as far as possible, meets the requirement that autonomous switching terminal is in cell edge;
(6) if this group A is semi-persistent scheduling in CELL2, then start timer t2 duration 150ms, carry out dynamic dispatching; Recovery on Timer Expiry semi-persistent scheduling, object ensures that listening user a to be independently switched to Target cell packet loss does not occur;
(7) after listening the t1 timing time-out of user a, be independently switched to Target cell CELL2, be switched to Target cell CELL2, owing to being with the business of RRC also can be switched to Target cell, being connected by RRC and report a CQI;
(8) CELL2 receives the CQI information of listening user a to report, and can readjust the MCS information that group A dispatches, meet the needs of actual schedule.
