Fig. 1 is the flow diagram of the cell switching method of one of embodiment of the present invention LC-MTC system, below will
It describes in detail in conjunction with cell switching method of the attached drawing 1 to one of embodiment of the present invention LC-MTC system, such as Fig. 1 institute
Show, the cell switching method of one of the present embodiment LC-MTC system may comprise steps of S101- step S103.
Step S101: the metrical information of user equipment (UE) is obtained.
Specifically, the access module that the UE is supported includes the enhancing suitable for narrow-band machine type communication LC-MTC
Cover type EC access module and non-EC access module.Wherein (Low-cost MTC, narrow-band machine type are logical by LC-MTC
Letter), it is a kind of standardized narrow-band technology of Internet of things specification of 3GPP Release 13, is only applicable in the bandwidth of 1.4MHz；EC
(Enhanced coverage enhances cover type mode), a kind of access module suitable for LC-MTC runs the UE of this mode,
The specifications such as its RSRP/RSRQ measurement reporting mechanism, system information acquisition are all made of LC-MTC mode.Rather than EC access module is then
The communication patterns such as the wireless communications mode in addition to EC access module, such as common 2G, 3G or 4G.It is understood that this
UE in invention is either support the LC-MTC terminal of EC access module, it is also possible to support the regular handset of LC-MTC whole
End.Wherein, metrical information includes the measurement report values of user equipment, such as Reference Signal Received Power RSRP (Reference
Signal Receiving Power) and Reference Signal Received Quality RSRQ (Reference Signal Receiving
Quality) value.It can also include under EC access module, UE connects to whether base station report needs to be maintained at EC in a long time
Enter the information such as mode, such as the instruction of estimate time in EC mode.
Step S102: the trigger area that the UE carries out cell switching is calculated according to the metrical information.
Specifically, the trigger area includes the first trigger area and the second trigger area, and first trigger area is
The UE can carry out the region of cell switching under EC access module and non-EC access module, and second trigger area is institute
State the region that UE can carry out cell switching under EC access module but be not available for cell switching under non-EC access module.
In being preferably carried out mode, the metrical information includes Reference Signal Received Quality RSRQ；According to the measurement
Information judges the current access module of the UE；If the UE current access module is EC access module, believed according to measurement
The RSRQ under EC access module in breath, calculates the RSRQ under non-EC access module；If the UE current access module is non-
EC access module calculates the RSRQ under EC access module then according to the RSRQ under EC access module non-in metrical information；According to institute
The difference between the RSRQ under the RSRQ and non-EC access module under EC access module is stated, the UE is calculated and carries out cell switching
Trigger area.
For example, UE_1 has reported the RSRQ#ec under EC access module to base station, base station is estimated according to the current location of UE_1
Calculate the RSRQ#normal under the non-EC access module of UE.It is estimated based on difference, if UE report is non-EC access module, base
Station can analyze the measurement report values of the EC access module of estimation UE；If what UE was reported is EC access module, base station can be estimated
Calculate the measurement report values of the non-EC access module of UE.Therefore by the above method, base station can be evaluated whether UE in EC access module and
In the case where non-EC access module whether can triggering cell switching, and there are following two situation, namely corresponding two kinds of trigger regions
Domain:
Situation 1:EC access module meeting triggering cell switching, non-EC access module also can triggering cell switchings；
Situation 2:EC access module meeting triggering cell switching, non-EC access module will not triggering cell switchings.
Wherein the first trigger area involved in the corresponding present invention of situation 1, situation 2 corresponding according to the present invention second
Trigger area.
Preferably for the UE of connected state, base station, which can analyze, compares UE in EC access module and non-EC access module
Metrical information in measurement report values between difference.Concrete methods of realizing can be by path loss and interference assessment, and ties
The statistical information for closing history measurement report Value Data is calculated.
Step S103: when detect the UE enter first trigger area, and the UE be in be suitable for LC-MTC
EC access module when, if judging, the UE needs to carry out cell and switches corresponding adjacent base station not supporting EC access module,
The UE is then controlled in cell switch process, stops EC access module and switch to the non-EC access module progress cell to cut
It changes.
Specifically, the first trigger area is that the UE can carry out cell under EC access module and non-EC access module and cut
The region changed, when detecting that UE enters first trigger area, and when UE be in EC access module, in the case, UE possibility
Cell switching, if UE is in EC access module at this time, the UE can be carried out under EC access module or under non-EC access module
It may be triggered under current EC access module and carry out cell switching, then UE is likely to the switching command returned according to base station
Start to switch, but work as and judge that the adjacent base station for carrying out cell switching is needed not support EC access module, switches occurred at this time,
And the corresponding adjacent base station in neighboring community after switching does not support EC access module, then will lead to cell handover failure, if
Again switching request is initiated after handover failure again, it will cause ping-pong effect, be bound to cause frequent signaling.Therefore,
In cell switch process in that case, need to judge that UE need to carry out cell and switch whether corresponding adjacent base station supports EC
Access module.If judging, adjacent base station does not support EC access module, which carries out cell switching under EC access module must
So it can lead to cell handover failure because of can not normally access EC access module.Therefore in order to guarantee that the cell of UE switches to
Function, serving BS should control or indicate UE in cell switch process at this time, stop the EC access module that UE is presently in and cut
It shifts to non-EC access module and carries out the cell switching, to guarantee that UE carries out the feasibility and stability of cell switching.
It should be noted that if access module change is controlled by base station, in access of the control UE in cell switch process
When mode keeps current access mode, the UE access module change signaling initiated can be postponed by base station,
Ignore or refuse, with the access module for keeping UE current；Another access is switched in cell switch process in control UE
When mode, active can handle the switch mode signaling that UE is initiated in time.
If access module change is controlled by UE itself, UE should refer to the method stream in above step S101 to step S104
Journey carries out the access module in cell switch process to UE and keeps or switch to carry out active judgement and holding, only need to be in access mould
Formula needs in handoff procedure, actively initiates the signaling that access module changes to serving BS.The present invention is to UE eventually by which kind of side
Formula carries out the holding or switching of access module, is not especially limited.
The embodiment of the present invention, by calculating the trigger region that UE carries out cell switching according to the metrical information of user equipment (UE)
Domain judges and indicates according to the current access module of the type of trigger area and UE when UE enters corresponding trigger area
The holding or switching of UE access module when carrying out the switching of cell, avoid in LC-MTC system UE in cell switch process
The problem of penalty of network system caused by due to the uncertainty of agreement operation, UE is improved in EC access module and non-
The stability and high efficiency of cell handover operations when the conversion of EC access module.
Fig. 2 and Fig. 3 is the flow diagram of the cell switching method of another LC-MTC system in the embodiment of the present invention,
The cell switching method of another LC-MTC system in the embodiment of the present invention is carried out below in conjunction with attached drawing 2 and attached drawing 3 detailed
Thin to introduce, as shown in Figures 2 and 3, the cell switching method of another LC-MTC system in the embodiment of the present invention may include
Following steps S201- step S208.
Step S201: obtaining the metrical information of user equipment (UE), and the access module that the UE is supported includes being suitable for narrow frequency
The enhancing cover type EC access module and non-EC access module of carrying machine type communication LC-MTC.
Specifically, it can correspond to reference to the method and step S101 in Fig. 1 embodiment, details are not described herein.
Step S202: the trigger area that the UE carries out cell switching, the trigger region are calculated according to the metrical information
Domain includes the first trigger area and the second trigger area, and first trigger area is that the UE connects in EC access module and non-EC
Enter carry out the region of cell switching under mode, second trigger area can carry out under EC access module small for the UE
Area switches but is not available for the region of cell switching under non-EC access module.
Specifically, it can correspond to reference to the method and step S102 in Fig. 1 embodiment, details are not described herein.
Step S203: when detect the UE enter first trigger area, and the UE be in be suitable for LC-MTC
EC access module when, if judging, the UE needs to carry out cell and switches corresponding adjacent base station not supporting EC access module,
The UE is then controlled in cell switch process, stops EC access module and switch to the non-EC access module progress cell to cut
It changes.
Specifically, it can correspond to reference to the method and step S103 in Fig. 1 embodiment, details are not described herein.
Step S204: when detect the UE enter first trigger area, and the UE be in be suitable for LC-MTC
EC access module when, if judging, the UE needs to carry out cell and switches corresponding adjacent base station to support EC access module,
Judge whether the UE indicates to keep EC access module within a preset period of time.
Specifically, when detecting that the UE enters first trigger area, and the UE is in suitable for LC-MTC
When EC access module, if judging, the adjacent base station supports EC access module, serving BS then to need the reality according to UE
Situation and demand carry out judgement and instruction that UE when cell switching needs holding or the access module switched.Preferably, according to institute
It states metrical information and judges whether the UE indicates to keep EC access module within a preset period of time, the metrical information includes working as institute
It states UE and is in the instruction the information whether UE under EC access module keeps EC access module within a preset period of time, instruction letter
Breath can be by AS layers of the access layer notice of UE to NAS layers of Non-Access Stratum of UE, and preceding notice can occur for the NAS layer of UE to core in switching
The NAS layer of heart net, such as mobile management nodes MME.
Step S205: if the determination result is YES, then controlling the UE in cell switch process, keep EC access module into
The row cell switching.
Specifically, if the judging result in step S204 be it is yes, indicate business demand amount of the UE under EC access module more
Greatly, it needs to carry out the business under EC access module in a long time, then indicates that UE is always maintained at EC in cell switch process
Access module can not initiate the request of the business of non-EC access module.
Step S206a: if judging result be it is no, control the UE in cell switch process, switch to non-EC access
Mode carries out the cell switching.
Specifically, if the judging result in step S204 be it is no, base station analyzes and determines that the switching of the UE is connect in non-EC
Enter mode still to carry out under EC access module.And judge to be the foundation carried out under non-EC access module or EC access module
It can be the consumption for considering core network signalling, due to the cell coverage area under non-EC access module, under non-EC access module
It is small, signal is strong, therefore switch robustness it is relatively preferable, so from switching robustness and core network signalling expense angle it is preferential
Cell switching is carried out under non-EC access module.
Further, the method flow in the step S206a in above-described embodiment, can also pass through following steps S206b
In method flow realize.
Step S206b: if judging result be it is no, control the UE according to the prestoring setting in UE and prestore setting pair described
The cell switching is carried out under the access module answered.
Specifically, if the judging result in step S204 be it is no, base station analyzes and determines that the switching of the UE is in normal mode
Formula still carries out under EC access module.The foundation of judgement can also be arranged based on the preset preference of user.For example, for
EC access module can be preset as priority access mode in advance by the frequent UE of LC-MTC business, user, it can be paid the utmost attention to
Do not change EC access module and carries out cell switching.
Step S207: when detecting that the UE enters first trigger area, and the UE is in non-EC access module
When, then the UE is controlled in cell switch process, and non-EC access module is kept to carry out the cell switching.
Specifically, the first trigger area is that the UE can carry out cell under EC access module and non-EC access module and cut
The region changed, when UE is in non-EC access module, since the cell coverage area under non-EC access module is small, signal is strong, because
The robustness of this switching is relatively preferable.So preferentially accessing mould in non-EC from the angle of switching robustness and core network signalling expense
Cell switching is carried out under formula.It preferably, in EC access module is also whether non-EC access module, in handoff procedure, it should to the greatest extent
It is constant that the mode can be able to maintain.
Step S208: when detect the UE enter second trigger area, and the UE be in be suitable for LC-MTC
EC access module when, then control the UE in cell switch process, keep the EC access module to carry out the cell and cut
It changes.
Specifically, since in that case, the second trigger area is that the UE can carry out cell under EC access module
Switching but the region that cell switching is not available under non-EC access module.Therefore when UE enters in the regional scope, non-
Under EC access module, will not triggering cell switching operation, so only discussing that UE is in the feelings of EC access module in this case
Condition, in this case, the second trigger area, UE could successfully initiate and execute cell to cut only under EC access module
Change, if therefore UE only keep current EC access module in the second trigger area, just can be carried out cell switching, take at this time
Business base station should control UE in cell switch process, keep the EC access module to carry out the cell switching, without it
Its optimization processing.
