It should be understood that in the present invention program, if there is the situation of " being equal to ", can be incited somebody to action according to actual conditions " being equal to " this case is ranged " being more than ", it is also possible to is ranged the situation of " being less than ", is not limited herein It is fixed.

It should be understood that in the method for cell switching control provided in an embodiment of the present invention, first community can be EHRPD cells, second community can be LTE cells, and in actual applications, first community can also be LTE cells, and second community can be eHRPD cells, and the excellent of first community is pre-configured with UE Priority of the first level higher than second community.

With the determination of the big unified trend of LTE network, cdma network is required consideration for how to LTE network Balance evolution, wherein, eHRPD network is exactly in order to cdma network is designed to LTE network evolution 's.For UE, in LTE network in an eHRPD cell of the UE in eHRPD network A LTE network switch over so that UE carries out corresponding industry in may reside within LTE cells Business.The relation between cdma network, eHRPD network and LTE network is explained below.

Three big normal structures of mobile communication industry, respectively 3GPP, 3GPP2 and worldwide interoperability for microwave Access (English full name：Worldwide Interoperability for Microwave Access, English contracting Write：WiMAX) alliance, although the mobile communication technology evolution path that this three big tissues and China propose is simultaneously Differ, but the network almost all of final deployment points to LTE.

It is Generation Mobile Telecommunication System technology (English full name from cdma network：2nd-Generation Mobile Communication, english abbreviation：2G), obtain a kind of for grouped data industry after evolution is carried out to it Cdma wireless communication technology that business is optimized, high spectrum utilization, as CDMA2000 1xEV-DO (English full name：Evolution Data Only), and the technology belongs to 3G (Third Generation) Moblie Technology (English full name：3rd-Generation Mobile Communication, english abbreviation：3G). LTE is evolved to from EV-DO to need to use " bridge " --- eHRPD network, and eHRPD network is The further evolution of EV-DO, it is possible to achieve the interoperability between LTE and EV-DO, and eHRPD nets Network can be with the shared wireless side resources of EV-DO, again can be with the shared core side resources of LTE.

The data service of EV-DO and LTE has three kinds of attainable schemes when interoperating, and the first is optimization Scheme, by the eHRPD and the interface of LTE network that increase newly, completes the pre-registration of eHRPD and cuts Change, LTE resources are discharged after the completion of switching, its advantage is offer lossless data service switching, switching time Less than 500 milliseconds, and have the disadvantage to need newly-increased eHRPD network and LTE network interface, and need into one Step upgrading access network, mobility management entity (English full name：Mobility management entity, English Text abbreviation：) and gateway (English full name MME：Serving gateway, english abbreviation： SGW), UE also needs to support pre-registration；Second is unoptimizable scheme, and UE detects LTE signals Network is weak, and eHRPD network signal it is good when, the connection of LTE network will be interrupted, and access EHRPD network continues data service, and its advantage is the biography that need not transform eHRPD network and LTE network System framework, has the disadvantage handoff delay about 2 seconds；It is enhancing unoptimizable scheme in 3rd, can be empty in LTE Not busy state completes the pre-registration of eHRPD network, and the eHRPD network of cycle return thereafter maintains session, and its is excellent Point is also the conventional architectures that need not transform eHRPD network and LTE network, has the disadvantage handover delay still It is more long, about 1 second, but the standard of the third scheme is also under discussion, and the realization of the present invention program exists Can be supported under the scene of above-mentioned three kinds of schemes.

Refer to Fig. 1 and side that Fig. 2, Fig. 1 are a kind of cell switching control provided in an embodiment of the present invention Method embodiment schematic diagram, Fig. 2 is that one flow of method of cell switching control in the embodiment of the present invention is illustrated Figure, the content with reference to shown in Fig. 1 and Fig. 2, the method for cell switching control can include：

101st, user equipment (UE) searches second community by obtaining better services BSR, wherein, UE Positioned at first community, the priority of the priority higher than first community of second community；

In the present embodiment, UE can periodically search for cell, if first community is eHRPD cells, And UE is in eHRPD cells, then second community, i.e. LTE cells can be searched at regular intervals, equally Ground, if first community is LTE cells, and UE can then search element at regular intervals in LTE cells Second community, i.e. eHRPD cells, when being resident first community, the time of periodically search can be according to reality Border situation is set, usually 2 minutes.

What is configured in UE is that second community priority is higher than first community, but due to resident LTE nets Network can bring preferably experience to user, thus general commercial network all to configure LTE network priority high In eHRPD network.

When UE searches second community, UE can send cell handover request to the network equipment, and this is small Area's handover request is used to illustrate the UE to need to carry out cell switching, now, cell handover request not generation Table UE must be switched over to second community, be only that triggering UE judges whether to need what is switched over One instruction.

102nd, UE obtains the signal quality parameter of second community；

In the present embodiment, UE can be by broadcast channel (the English full name of base station UE：Broadcast Channel, english abbreviation：BCH) signal quality parameter of second community is obtained.Wherein, BCH bags Include BCCH (English full name：Broadcast Control Channel, english abbreviation：BCCH)、 Frequency correction channel (English full name：Frequency Correction Channel, english abbreviation：FCCH) With synchronizing channel (English full name：Synchronization Channel, english abbreviation：SCH), in communication In net, BCH is unidirectional down channel, that is to say, that from base station to user equipment, BCCH is mainly used In system message is sent, FCCH is mainly effect positive frequency, and SCH is synchronizing channel, and they are all to use What the mode of point-to-multipoint was transmitted.

Specifically, the signal quality parameter can be Reference Signal Received Power (English full name： Reference Signal Received Power, english abbreviation：RSRP), RSRP is in certain measurement In bandwidth, cell special reference (English full name：Cell-specific Reference Signal, English Abbreviation：CRS mean receiving power), and be in respective orthogonal frequency division multiplexing (English full name： Orthogonal Frequency Division Multiplexing, english abbreviation：OFDM) symbol is useful Partial mean receiving power, usual RSRP is higher, and its signal quality is better.

Signal quality parameter can also be Signal to Interference plus Noise Ratio (English full name：Signal to Interference Plus Noise Ratio, english abbreviation：SINR), SINR reflects connecing for reference signal Quality is received, and, the quality of reception of reference signal is also only reflected, usual SINR is higher, and signal is got over Can correctly demodulate, channel circumstance is better, transmission rate is also better.

Signal quality parameter can also be received signal strength indicator (English full name：Received Signal Strength Indicator, english abbreviation：RSSI), RSSI is the pilot tone symbol in certain Measurement bandwidth The average value of total received power on number in measure the cycle, RSSI reflections are entirely to include CRS The total received power of OFDM symbol, includes useful signal, Cyclic Prefix, intra-cell interference, adjacent small Area's interference and noise etc. are in interior all power.Under normal circumstances, RSSI is higher, and its signal is better.

It should be noted that in actual applications, signal quality parameter can also be other parameters, or Person is the signal quality parameter that multiple parameters are calculated jointly, is not limited herein.

If the 103, the signal quality parameter of second community is less than preset thresholding, UE does not carry out cutting for cell Change.

In the present embodiment, if the signal quality parameter of second community is prescribed a time limit less than preset gate, UE meetings Judge now whether UE needs to carry out cell switching according to thresholding set in advance, can be specifically UE One preset thresholding can be set itself, after the signal quality parameter for getting second community, judge this Whether the signal quality parameter of two cells is less than preset thresholding, and cell is not carried out then if less than preset thresholding Switching.If just prescribed a time limit equal to preset gate, cell switching can be carried out according to rule set in advance, Or cell switching is not carried out according to rule set in advance, therefore, the signal quality parameter of second community Can be flexibly set according to actual conditions equal to the processing mode that preset gate is prescribed a time limit.

Wherein, preset thresholding can be the thresholding that User Defined is set so that retention signal is not low for UE In the cell for setting preset thresholding, second community of a retention signal quality higher than preset thresholding.Such as, In actual applications, UE may reside within -105 decibels of (English full name：Decibe, english abbreviation： Db cell), then at this point it is possible to by preset thresholding be set as -95Db, or other be higher than The threshold value of -105Db, does not limit herein.

In order to make it easy to understand, can be described from following two scenes respectively, i.e. first community and second Cell is not adjacent area, and first community and second community adjacent area each other situation, below by from UE's Angle is described to the method for cell switching control in the embodiment of the present invention：

First, first community and second community are not adjacent area；

Alternatively, on the basis of the corresponding embodiments of above-mentioned Fig. 2, cell provided in an embodiment of the present invention In first alternative embodiment of method of switching control, UE obtain second community signal quality parameter it Afterwards, can also include：

If the signal quality parameter of second community is more than preset thresholding, and first community is not with second community Adjacent area, then UE switch to second community from first community；

If the signal quality parameter of second community is more than preset thresholding, and first community is with second community each other Adjacent area, then UE do not carry out the switching of cell.

In the present embodiment, Fig. 3 is referred to, Fig. 3 is that first community is not with second community in the embodiment of the present invention The schematic diagram of cell switching is carried out during for adjacent area, with eHRPD cells (A cells) as first community in figure, It is introduced so that LTE cells (B cells) are as second community as an example.As shown in figure 3, current network ring There is eHRPD cell A and LTE cell B in border, both not adjacent areas each other.The client identification module of UE (English full name：Subscriber Identity Module, english abbreviation：SIM LTE nets) are pre-configured with Network priority is higher than eHRPD network, and the time of LTE cells is periodically searched for when being resident eHRPD cells It can be 2 minutes.If UE rests on certain border of LTE cells to obtain better services Region, but the regional signal is weaker, easily falls net, then LTE cells will occur and fall net and return To eHRPD cells, the situation of ping-pong reselection is formed.Therefore, UE is judging whether that LTE can be switched to During cell, can be by judging whether the signal quality parameter of LTE cells determines more than preset thresholding.

Specifically, when second community is LTE cells, then UE judges the signal quality ginseng of LTE cells Whether number is more than preset thresholding, if the signal quality parameter of LTE cells is more than preset thresholding, UE can Second community is switched to from first community, i.e., switches to LTE cells from eHRPD cells.

Even if the signal quality parameter of second community is more than preset thresholding, but if with first community each other During adjacent area, also do not switch over.When second community not with first community adjacent area each other, and second community Signal quality parameter is prescribed a time limit more than preset gate, then search second community by BSR, and carry out cell and cut Change.

2nd, first community and second community adjacent area each other；

Alternatively, on the basis of the corresponding embodiments of above-mentioned Fig. 2, cell provided in an embodiment of the present invention In second alternative embodiment of method of switching control, UE obtains the signal quality parameter of second community, Can include：

In the present embodiment, Fig. 4 is referred to, Fig. 4 is that first community is mutual with second community in the embodiment of the present invention The schematic diagram of cell switching is carried out during for adjacent area, with eHRPD cells (A cells) as first community in figure, With LTE cells (B cells) as second community, with not with first community and second community adjacent area each other LTE cells as a example by the 3rd cell used as being introduced.As shown in figure 3, there is eHRPD in current network conditions Cell A, LTE cell B and LTE cell C, wherein eHRPD cells A and LTE cells B are configured It is adjacent area.The SIM of UE is pre-configured with LTE network priority higher than eHRPD network, is resident eHRPD Periodically the time of search LTE cells can be 2 minutes during cell.If UE is in order to obtain more preferably clothes Business, and search LTE cells and rest on certain borderline region of LTE cells, but the regional signal It is weaker, then UE can occur the gravity treatment from LTE cells B to eHRPD cells A, form table tennis The situation of gravity treatment, in can be addition LTE cell C, for being resident and provides business.
