Fig. 1 is the schematic flow sheet of the cell switching method of a kind of LC-MTC system in the embodiment of the present invention, cell switching method below in conjunction with a kind of LC-MTC system in accompanying drawing 1 pair of embodiment of the present invention describes in detail, as shown in Figure 1, the cell switching method of a kind of LC-MTC system in the present embodiment can comprise the following steps S101-step S103.
Step S101: the metrical information obtaining user equipment (UE).
Particularly, the access module that described UE supports comprises, and is applicable to the enhancing cover type EC access module of narrow-band machine type communication LC-MTC, and non-EC access module.Wherein LC-MTC (Low-costMTC, narrow-band machine type communication), is the standardized a kind of narrow-band technology of Internet of things specification of 3GPPRelease13, is only suitable for the frequency range of 1.4MHz; EC (Enhancedcoverage strengthens cover type pattern), a kind of access module being applicable to LC-MTC, runs the UE of this pattern, and its RSRP/RSRQ measures the specification such as reporting mechanism, system information acquisition and all adopts LC-MTC pattern.But not EC access module is then the wireless communications mode except EC access module, the communication patterns such as such as common 2G, 3G or 4G.Be understandable that, the UE in the present invention both can be the LC-MTC terminal supporting EC access module, also may be the regular handset terminal supporting LC-MTC.Wherein, metrical information comprises the measurement report values of subscriber equipment, as Reference Signal Received Power RSRP (ReferenceSignalReceivingPower) and Reference Signal Received Quality RSRQ (ReferenceSignalReceivingQuality) value.Under can also comprising EC access module, UE reports such as, the need of remaining on the information such as EC access module in a long time, the instruction of estimatetimeinECmode to base station.
Step S102: calculate the toggle area that described UE carries out cell merge according to described metrical information.
Particularly, described toggle area comprises the first toggle area and the second toggle area, described first toggle area is the region that described UE all can carry out cell merge under EC access module and non-EC access module, and described second toggle area is that described UE can carry out cell merge but under EC access module, carry out the region of cell merge under EC access module.
In preferably execution mode, described metrical information comprises Reference Signal Received Quality RSRQ; The access module that described UE is current is judged according to described metrical information; If the current access module of described UE is EC access module, then according to the RSRQ under the EC access module in metrical information, calculate the RSRQ under non-EC access module; If the current access module of described UE is non-EC access module, then according to the RSRQ under EC access module non-in metrical information, calculate the RSRQ under EC access module; According to the difference between the RSRQ under the RSRQ under described EC access module and non-EC access module, calculate the toggle area that described UE carries out cell merge.
Such as, UE_1 has reported the RSRQ#ec under EC access module to base station, and the RSRQ#normal under the non-EC access module of UE, according to the current location of UE_1, is estimated in base station.Based on difference estimation, if UE reports is non-EC access module, base station can the measurement report values of EC access module of analytical estimating UE; If what UE reported is EC access module, the measurement report values of the non-EC access module of UE can be estimated in base station.Therefore by said method, base station can estimate whether UE can switch triggering cell when EC access module and non-EC access module, and there are following two kinds of situations, is also corresponding two kinds of toggle area:
Situation 1:EC access module can switch triggering cell, and non-EC access module also can switch triggering cell;
Situation 2:EC access module can switch triggering cell, and non-EC access module can not switch triggering cell.
The first wherein involved in the corresponding the present invention of situation 1 toggle area, the second toggle area that situation 2 is corresponding involved in the present invention.
Preferably, for the UE of connected state, base station can difference between the measurement report values in the metrical information of com-parison and analysis UE when EC access module and non-EC access module.Concrete methods of realizing by path loss and interference assessment, and can calculate in conjunction with the statistical information of history measurement report Value Data.
Step S103: when detecting that described UE enters described first toggle area, and described UE is when being in the EC access module being applicable to LC-MTC, if judge, described UE needs to carry out adjacent base station corresponding to cell merge and does not support EC access module, then control described UE in cell switch process, stop EC access module and switch to non-EC access module carrying out described cell merge.
Particularly, first toggle area is the region that described UE all can carry out cell merge under EC access module and non-EC access module, when detecting that UE enters this first toggle area, and UE is when being in EC access module, in the case, UE may carry out cell merge under EC access module or under non-EC access module, if when now UE is in EC access module, then this UE may trigger and carry out cell merge under current EC access module, the switching command that then UE has probably returned according to base station starts to switch, but when judging that the adjacent base station needing to carry out cell merge does not support EC access module, now switch and occur, and adjacent base station corresponding to neighbor cell after switching does not support EC access module, then can cause cell merge failure, if again again initiate handover request after handoff failure, ping-pong effect will be caused, signaling frequently certainly will be caused.Therefore, in cell switch process in that case, need to judge that UE need carry out adjacent base station corresponding to cell merge and whether support EC access module.If judge, adjacent base station does not support EC access module, then this UE carry out under EC access module cell merge will inevitably cause because of cannot normally access EC access module cell merge failure.Therefore in order to ensure the cell merge success of UE, now serving BS should control or indicate UE in cell switch process, stop the current residing EC access module of UE and switch to non-EC access module carrying out described cell merge, to ensure that UE carries out feasibility and the stability of cell merge.
It should be noted that, if access module changes be controlled by base station, when the access module of control UE in cell switch process keeps current access mode, signaling can be changed by base station for the access module that this UE initiates to carry out postponing, ignore or refusing, with the access module keeping UE current; When control UE is switched to another kind of access module in cell switch process, can to initiatively processing in time the switch mode signaling that UE initiates.
If access module changes be controlled by UE itself, then UE should with reference to the method flow in above step S101 to step S104, keep or switch carrying out active judgement and keeping to the access module that UE carries out in cell switch process, only need need in handoff procedure at access module, initiatively initiate the signaling of access module change to serving BS.The present invention carries out maintenance or the switching of access module eventually through which kind of mode to UE, do not do concrete restriction.
The embodiment of the present invention, by calculating according to the metrical information of user equipment (UE) the toggle area that UE carries out cell merge, when UE enters corresponding toggle area, judge according to the type of toggle area and the current access module of UE and indicate maintenance or the switching of UE access module when carrying out the switching of community, avoid the problem of the penalty of the network system that UE causes because of the uncertainty of agreement operation in cell switch process in LC-MTC system, improve stability and the high efficiency of the cell handover operations of UE when the conversion of EC access module and non-EC access module.
Fig. 2 and Fig. 3 is the schematic flow sheet of the cell switching method of another kind of LC-MTC system in the embodiment of the present invention, cell switching method below in conjunction with the another kind of LC-MTC system in accompanying drawing 2 and accompanying drawing 3 pairs of embodiment of the present invention describes in detail, as shown in Figures 2 and 3, the cell switching method of the another kind of LC-MTC system in the embodiment of the present invention can comprise the following steps S201-step S208.
Step S201: the metrical information obtaining user equipment (UE), the access module that described UE supports comprises, and is applicable to the enhancing cover type EC access module of narrow-band machine type communication LC-MTC, and non-EC access module.
Particularly, can method step S101 in corresponding reference diagram 1 embodiment, do not repeat them here.
Step S202: calculate the toggle area that described UE carries out cell merge according to described metrical information, described toggle area comprises the first toggle area and the second toggle area, described first toggle area is the region that described UE all can carry out cell merge under EC access module and non-EC access module, and described second toggle area is that described UE can carry out cell merge but under EC access module, carry out the region of cell merge under EC access module.
Particularly, can method step S102 in corresponding reference diagram 1 embodiment, do not repeat them here.
Step S203: when detecting that described UE enters described first toggle area, and described UE is when being in the EC access module being applicable to LC-MTC, if judge, described UE needs to carry out adjacent base station corresponding to cell merge and does not support EC access module, then control described UE in cell switch process, stop EC access module and switch to non-EC access module carrying out described cell merge.
Particularly, can method step S103 in corresponding reference diagram 1 embodiment, do not repeat them here.
Step S204: when detecting that described UE enters described first toggle area, and described UE is when being in the EC access module being applicable to LC-MTC, if judge, described UE needs to carry out adjacent base station corresponding to cell merge and supports EC access module, then judge whether described UE indicates and keep EC access module in preset time period.
Particularly, when detecting that described UE enters described first toggle area, and described UE is when being in the EC access module being applicable to LC-MTC, if judge, described adjacent base station supports EC access module, then serving BS then needs actual conditions according to UE and demand, and when carrying out cell merge, UE needs judgement and the instruction of the access module keeping or switch.Preferably, judge whether described UE indicates according to described metrical information and keep EC access module in preset time period, described metrical information comprises described UE under described UE is in EC access module in preset time period, whether keeps the indication information of EC access module, this indication information can be informed the Non-Access Stratum NAS layer of UE by the Access Layer AS layer of UE, the NAS layer of UE can inform the NAS layer of core net before switching generation, as mobile management nodes MME.
Step S205: if the determination result is YES, then control described UE in cell switch process, keeps EC access module to carry out described cell merge.
Particularly, if the judged result in step S204 is yes, represent that the business demand amount of UE under EC access module is larger, need to carry out in a long time the business under EC access module, then indicate UE to keep EC access module in cell switch process always, namely cannot initiate the request of the business of non-EC access module.
Step S206a: if judged result is no, then control described UE in cell switch process, switches to non-EC access module and carries out described cell merge.
Particularly, if the judged result in step S204 is no, then base station is analyzed and is judged that the switching of this UE is at non-EC access module or carries out under EC access module.And judge to be the foundation of carrying out under non-EC access module or EC access module can be consider the consumption of core network signalling, due under non-EC access module, cell coverage area under non-EC access module is little, signal is strong, therefore the robustness switched is relatively better, so preferentially carry out cell merge under non-EC access module from the angle switching robustness and core network signalling expense.
Further, the method flow in the step S206a in above-described embodiment, can also be realized by the method flow in following steps S206b.
Step S206b: if judged result is no, according to prestoring in UE arrange control described UE described prestore corresponding access module is set under carry out described cell merge.
Particularly, if the judged result in step S204 is no, then base station is analyzed and is judged that the switching of this UE carries out at normal mode or under EC access module.The foundation judged also can be arranged based on the preference preset of user.Such as, for LC-MTC business UE frequently, EC access module can be preset as priority access pattern by user in advance, namely can pay the utmost attention to and does not change EC access module and carry out cell merge.
Step S207: when detecting that described UE enters described first toggle area, and when described UE is in non-EC access module, then controlling described UE in cell switch process, keeping non-EC access module to carry out described cell merge.
Particularly, first toggle area is the region that described UE all can carry out cell merge under EC access module and non-EC access module, when UE is in non-EC access module, because the cell coverage area under non-EC access module is little, signal is strong, and the robustness therefore switched is relatively better.So preferentially carry out cell merge under non-EC access module from the angle switching robustness and core network signalling expense.Preferably, no matter be also non-EC access module at EC access module, in handoff procedure, this pattern should be kept as far as possible constant.
Step S208: when detecting that described UE enters described second toggle area, and when described UE is in the EC access module being applicable to LC-MTC, then controlling described UE in cell switch process, keeping described EC access module to carry out described cell merge.
Particularly, due in that case, the second toggle area is that described UE can carry out cell merge but under EC access module, carry out the region of cell merge under EC access module.Therefore when UE enters in this regional extent, under non-EC access module, can not triggering cell switch operation, so only discuss the situation that UE is in EC access module in this case, in such cases, the second toggle area, UE is only under EC access module, could successfully initiate and perform cell merge, if therefore UE is in the second toggle area, only have and keep current EC access module, just cell merge can be carried out, now serving BS should control UE in cell switch process, described EC access module is kept to carry out described cell merge, do not carry out other optimization process.
