Specific embodiment

To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention Specific embodiment be described in detail.Detail is elaborated in the following description to fully understand the present invention.But It is that the present invention can be implemented with a variety of different from other way described herein, those skilled in the art can be without prejudice to originally Similar popularization is done in the case where invention intension.Therefore the present invention is not limited by following public specific embodiment.

Inventors have found that user equipment in the prior art is lacked from the mode that 2G/3G network returns to LTE network there are some It falls into.

Specifically, when user equipment returns to LTE network by cell reselection mode, return speed is slow, when extend, it is real When property is poor.This is because user equipment needs after circuit domain business, 2G/3G network is first resided in, and carry out LTE Gravity treatment is to LTE network after the measurement and evaluation process of network.Which increase the time delays for returning to LTE network, and it is quick to be unfavorable for user Access the data service of High Data Rate.

When user equipment returns to LTE network by quick echo plex mode, due to the correlation for needing to issue in 2G/3G network It is carried in message (such as RRC Connection Release message or Channel Release message) and is redirected to LTE The target information of network, it is therefore desirable to which the network side equipment in 2G/3G network supports the mode, is needed thus to existing 2G/3G network is upgraded, and the increase of cost and the waste of resource are inevitably resulted in.Also, upgrade of network is usually one Prolonged process, be along with the process of deployment of entire LTE network.Therefore, in a long time, can exist and not support quickly Back to the 2G/3G network of LTE network.

In addition, inventor also found, in quick echo plex mode in the prior art, when the correlation that 2G/3G network issues disappears In the case of carrying redirection information in breath, some shortcomings is still remained.

For example, when the target information for being redirected to LTE network carried in the message is wrong, user equipment is by nothing Method is accurately and timely back to LTE network, leads to quick return course failure indicated by network.

This failure is inevitable in some cases, for example, 2G/3G network is to user device configuration LTE net The adjacent cell information of network, and user equipment is required to carry out reporting for event triggered fashion, such as when LTE neighboring area signal is enough By force, report measurement results when 2G/3G network signal is weak enough.If under this scene, when user equipment is located at 2G/ for a long time Near the base station of 3G network, the signal of LTE base station is weaker than 2G/3G base station signal always, then the measurement event never triggers. At this moment, when user equipment finishes circuit domain business, target LTE redirection information that 2G/3G network is configured (such as in 3G In network, the target cell information list that is configured by Redirection info cell) it is not based on user equipment pair The measurement result of LTE network, then often configuration error or invalid target LTE cell cause quickly to return to user equipment Procedure failure.

For another example, it attempts to return to LTE network mistake when according to the target information for being redirected to LTE network in the return message After losing, introduction is not provided in the prior art yet, so that user equipment can again attempt to return more quickly to LTE network.

In addition, it is believed by the inventors that supporting the situation of LTE network and at least another cordless communication network in user equipment Under, it is more satisfactory selection in some scenarios to LTE network that user equipment, which is resident,.However, in the prior art, when in 2G/ After circuit domain business in 3G network, if the redirection target information carried in the return message that 2G/3G network issues It is 2G/3G network, user equipment will switch to 2G/3G network indicated by redirection target information according to the return message, Rather than LTE network.

This problem may occur particularly in user equipment and fall back to 2G/3G network from LTE network by CSFB mode Situation.Since user equipment is fallen after rise from LTE network, then returning to LTE network will more manage at the end of circuit domain business Think.But the quick return redirection target that 2G network is configured may not be LTE network, but it is improper in this case 3G network.

Such inappropriate configuration, it may be possible to since 2G network does not upgrade, i.e., not due to the appearance of LTE network and Update its configuration information；It is also likely to be since 2G network thinks that user equipment is switched in from 3G network, then should return to 3G network.

Embodiments of the present invention are different from the technical measures of the above-mentioned prior art by providing, relatively more superior to obtain Technical effect.

It is resident from non-LTE network to LTE network as shown in Figure 1, embodiments of the present invention provide a kind of user equipment Method.

Step S 110, user equipment are fallen after rise from LTE network to non-LTE network；

In present specification, non-LTE network includes 2G/3G network.Here, the 2G/3G network should make amplified interpretation, packet Include usually said 2G communication system, 2.5G communication system, 2.75G communication system and 3G communication system, 3.5G communication system, 3.75G communication system etc..

The mode that user equipment is fallen after rise from LTE network to non-LTE network includes in such a way that network signal instruction is fallen after rise (such as LTE network indicates that user equipment goes non-LTE network by redirection mode, switching mode etc.), reselection modes and network Way of search etc..

In general, user equipment is resident from LTE network in addition to roaming and gravity treatment under normal standby mode between cross-system It may be in order to realize circuit domain business in non-LTE network, such as voice service, supplementary service, positioning service to non-LTE network Deng.In such cases, it can be realized using CSFB mode.

Specifically, user equipment falls back to GSM network from LTE network, can pass through RRCConnection Release With redirection message or RRC Connection Release withredirection with SIBs message Etc. modes realize.

User equipment falls back to TD-SCDMA network from LTE network, can pass through RRCConnection Release With redirection message, RRC Connection Release withredirection with SIBs message or Person's PS Handover(packet domain switching) etc. modes realize.

User equipment falls back to WCDMA network from LTE network, can use side identical with TD-SCDMA network is fallen back to Formula, can also use DMCR(Deferred MeasurementControl Reading, delay read measurement control) mode.

In addition, when the terminal for residing in LTE network is in data service connected state, in addition to aforesaid way, user equipment UE gravity treatment, Cell Change Order (Cell ChangeOrder, i.e. CCO), gravity treatment of network-control controlled etc. can also be passed through Mode falls back to 2G/3G network.

Certainly, user equipment, which switches or is resident to the business that non-LTE network to be carried out from LTE network, is also not necessarily limited to circuit Domain business, for example, network switching can be carried out based on the demand of user or other various possible application scenarios.

Step S 120, during non-LTE network, user equipment carries out LTE nearby region measurement, to obtain LTE nearby region measurement knot Fruit；

In general, user equipment is circuit domain business in the business that non-LTE network carries out.It is of course also possible to be packet domain industry Business or circuit domain business and packet switch domain service are concurrent, should not excessively be limited herein.

It will be understood to those skilled in the art that user equipment is fallen after rise to before non-LTE network, LTE network can be received The LTE frequency point list issued, such as in the LTE technical specification defined in 3GPP, " MeasObjectEUTRA " cell is described The adjacent cell information list for needing to measure in the LTE system of the be allocated to user equipment of LTE network.In addition, hair of the invention Bright people proposes that LTE network can also configure LTE networking frequency point list and be issued to user equipment.

The LTE frequency point list includes but is not limited to LTE adjacent frequency point list.

Frequency point information needed for the LTE networking frequency point list generally includes networking and Black Cell list.

After user equipment falls back to non-LTE network, user equipment can still save the LTE that the LTE network issues Frequency point list and/or LTE networking frequency point list.

After user equipment falls back to non-LTE network, the current non-LTE network for carrying out business is configured with LTE Neighboring cell list, it is also possible to LTE neighboring cell list be not configured.For example, in the technical specification defined in 3GPP, " E-UTRA Frequency list " cell and " E-UTRA frequency andpriority info list " cell describe 3G system It can be used for being allocated to the LTE neighbor cell list of user equipment；" E-UTRAN Parameters Description " cell Describing 2G system can be used for being allocated to the LTE neighbor cell list of user equipment.In addition, it should be noted that, in non-LTE net During network carry out business, user equipment may switch between multiple cells in the same non-LTE network system, it is also possible to It switches between different types of non-LTE network system.In the cell or system of the user equipment access, may all it match It is equipped with LTE neighboring cell list, it is also possible to LTE neighboring cell list all be not configured, or at least one is configured with LTE neighboring cell list.

Therefore, user equipment, which carries out LTE neighboring BS information used in LTE nearby region measurement, may be from LTE network, it is also possible to From non-LTE network.It is also possible to be to comprehensively consider the LTE neighboring BS information from LTE network and the adjacent area letter from non-LTE network Breath carries out LTE nearby region measurement.

It should be noted that the LTE nearby region measurement can be carried out in the business of non-LTE network carries out with user equipment, It is also possible to after the service ending of non-LTE network.

Step S130, user equipment terminate after the business of non-LTE network, are attempted according to the LTE nearby region measurement result Actively it is resident to LTE network.

The business terminated in non-LTE network, it may be possible to be initiated by user equipment, it is also possible to it is initiated by network side, It is also likely to be since the factors such as emergent Radio Link Failure cause during business progress.

For example, voice service may be hung up the telephone due to user equipment side, it is also possible to since the other side of call hangs up the telephone, It may also be requested due to refusal, or abruptly enter elevator to lead to link down without signal covering.

For the service ending process that user equipment or network side are initiated, the normal signaling of technical specification defined is had Process, user equipment can receive the RRC Connection Release message (under 3G network) or Channel that network issues Release message (under 2G network) or Rejection message, and these message may carry and be redirected to LTE network Target cell information list.

And for the service ending as brought by Radio Link Failure, user equipment can not then carry out normal business knot Signaling process needed for beam process will not receive the redirection information that network side is configured.

The active is resident to LTE network, and active meaning is not in some aspects it is to be understood that in the instruction of network Under, nor due to according to prior art specification, such as the originals such as more preferably of the signal due to only existing LTE network or LTE network Cause, in the case where needing to reselect to LTE network, LTE network is resident in user equipment trial.Also that is, user equipment is in root According to prior art specification, does not need or LTE network will not be selected to carry out in the case where being resident, be resident LTE network.

The trial is actively resident to LTE network, be typically may occur in user equipment and is needed to return from non-LTE network When LTE network, network side be not configured redirection information or network side configuration redirection information is invalid or the weight of network side configuration The non-LTE objective network information of directed information or according to network side instruction return LTE network procedure failure in the case of.

For step S120 obtain the LTE nearby region measurement as a result, user equipment can according to all nearby region measurements as a result, Resident target LTE cell is attempted according to default rule selection.For example, it may be being ranked up to measurement result, according to survey The ordering scenario of magnitude successively attempts LTE cell；For another example, power threshold is set, is selected in LTE nearby region measurement result Measured value is more than that the LTE cell of power threshold is attempted；The power threshold can be cell reselection thresholding or other can The threshold value of energy.Common power threshold for example can be RSRP(Reference Signal ReceivingPower, refer to Signal reception power)/RSRQ(Reference Signal Receiving Quality, the reference information quality of reception) thresholding.

Under the mode of setting power threshold, if there is no measured values more than power threshold in LTE nearby region measurement result LTE cell, then without being resident to the trial of LTE network.

Or if LTE is carried out there is no the LTE cell that measured value is more than power threshold in LTE nearby region measurement result The normal processes such as search, measurement, the PLMN selection of network, to attempt to be resident to LTE network.Wherein, the LTE network is searched The processes such as rope, measurement, PLMN selection can be carried out using mode defined in prior art specification.

The mode that user equipment is actively resident LTE network can according to need to be selected with actual conditions, for example, can To be requested using user equipment to target LTE cell initiating updating of tracking area (TrackingArea Update, be abbreviated as TAU), The modes such as cell update message or location area updating message；The PLMN(Public Land of user equipment execution LTE network Mobile Network, public land mobile network) selection, it registered in LTE network, adhered to, the agreements institute such as cell selection Defined process.

The beneficial effect of embodiments of the present invention is that user equipment can be returned quickly after non-LTE network winding-up It is back to LTE network, and then is capable of the data services capability of quick obtaining High Data Rate, avoids not configuring due to non-LTE network Target cell is quickly returned to, the quick return Target cell perhaps configured, target network are not suitable for or due to unexpected nothing Link down caused by wired link failure causes user equipment that can not receive under the scenes such as the Target cell of network configuration, brings Return LTE network delay.

In present embodiment, LTE network is actively resident in user equipment trial, including according to obtaining in step S120 LTE nearby region measurement result determines target LTE cell, attempt resident.

In addition, in other embodiments, user equipment also may include carrying out after the service ending of non-LTE network The normal processes such as search, measurement, the PLMN selection of LTE network defined in prior art specification attempt actively resident.

The progress LTE network search is to attempt actively to be resident to the process of LTE network, it may occur however that in user equipment root It is carried out after attempting resident failure according to LTE nearby region measurement result, it is also possible to which generation can not select survey according to LTE nearby region measurement result In the case of magnitude is more than the target LTE cell of RSRP/RSRQ thresholding.

That is, if user equipment, which is got, can be used in independently determining that target LTE is small during non-LTE network The LTE network information (result searched for including the LTE nearby region measurement result or the LTE network) in area, in non-LTE network Service ending after or other need to return LTE network scene under (such as after the service ending of non-LTE network), can be with It attempts actively to be resident to LTE network according to the LTE network information.

It should be noted that described includes that user equipment is returned from LTE network during non-LTE network in present specification Non- LTE network is dropped down onto, during being not yet successfully resident to before LTE network.

As shown in fig. 7, embodiments of the present invention provide a kind of method for carrying out LTE nearby region measurement in non-LTE network.

Step S710 selects LTE cell range to be measured in the LTE neighboring BS information that user equipment saves；

In present embodiment, the LTE neighboring BS information that user equipment saves may include the LTE frequency point column that LTE network issues The LTE neighboring cell list of table and/or LTE networking frequency point list, and/or the configuration of non-LTE network.The LTE frequency point column that LTE network issues Table usually describes in " MeasObjectEUTRA " cell；The LTE neighboring cell list of non-LTE network configuration, usually in " E-UTRA Frequency list " cell and " E-UTRA frequency and priority info list " cell, or " E- It is described in UTRANParameters Description " cell.The LTE networking frequency point list that LTE network issues, the LTE group Net frequency point list, does not describe in existing technical specification.

In disclosed LTE networking frequency point list, the range of frequency point or LTE cell is greater than Neighboring cell list described in " MeasObjectEUTRA " cell.Neighboring cell list described in " MeasObjectEUTRA " cell, The list of neighboring community usually on the be located at current service cell geographical location of user equipment；And networking list then may be The entire LTE network range of current PLMN, or may at least be deposited in a larger region, such as a city scope LTE frequency point or cell list.Therefore, the record length of networking list can be greater than in " MeasObjectEUTRA " cell The neighboring cell list of description.Networking list is usually sent to user equipment by the broadcast channel of LTE network in a broadcast manner.

The selection rule of LTE cell to be measured can flexibly be configured according to actual scene and demand.

For example, when only exist above-mentioned three classes LTE neighboring BS information for the moment, then using the cell in the LTE neighboring BS information as LTE cell to be measured.

When LTE neighboring BS information includes at least two class LTE neighboring BS information, the intersection of all neighboring BS information can also be measured.

Alternatively, newest one kind LTE neighboring BS information is selected when LTE neighboring BS information includes at least two class LTE neighboring BS information It is set to LTE cell range to be measured；Or effective and newest one kind LTE neighboring BS information is chosen to be LTE cell model to be measured It encloses.Alternatively, effective LTE neighboring BS information is chosen to be LTE cell range to be measured.

It, can be according to the change of LAI, RAI and Cell ID in one kind in the specific implementation, when selecting LTE cell range to be measured Change the validity that situation determines LTE neighboring BS information.LAI is Location Area Identification, and RAI is Routing Area Identifier, and Cell ID is cell mark Know.

For ease of understanding, several situations of change according to LAI, RAI and Cell ID are given below and determine LTE neighboring BS information Validity example:

If Cell ID does not change, then it is assumed that the LTE that LTE neighboring cell list that 2G or 3G network issue, LTE network issue Frequency point list and LTE networking frequency point list are effective；

If Cell ID changes, LAI does not change, then it is assumed that the LTE frequency point list and LTE networking frequency point that LTE network issues List is effective；

If Cell ID changes, LAI and RAI change, then it is assumed that the LTE frequency point list and LTE group that LTE network issues Net frequency point list is invalid.

Wherein, the situation of change of LAI, RAI and Cell ID refers to when the business of circuit domain carries out in processing circuit domain Business network in variation.For example, user equipment does not move, but from 2G network switching to 3G network, then its Cell ID is switched to the CellID of 3G from the Cell ID of 2G, and such variation should not be used at any time as judgement The validity of LTE neighboring BS information.Due to the fact that the relationship of the adjacent area LTE changes there is no the change because of this kind of Cell ID Become.But it if the change of the Cell ID of current service cell in 3G or 2G system, has occurred in user equipment, then usually says Bright, enough position movements have occurred in user equipment, then the adjacent area LTE of its serving cell can generally also change, in turn Influence whether the validity of three classes LTE neighboring BS information.

LAI, RAI and Cell ID facilitate deciding on the validity of the LTE neighboring BS information of newest one kind.What LTE network issued LTE frequency point list and/or LTE networking frequency point list, after user equipment falls back to non-LTE network from LTE network, usually no longer It is updated.The LTE neighboring BS information that may be continually updated is the LTE neighboring cell list configured by non-LTE network.But in non-LTE net The business duration of network, user equipment may be switched to another cell by a cell, it is also possible to by a system, example Such as 2G, it is switched to another system, such as 3G.During this, in each serving cell, the adjacent area LTE may may not also be configured List.In general, whenever, it is believed that the LTE neighboring cell list that this current service cell is configured is effective, Er Qieshi It is preferred that select, that is, it is not necessarily to the neighboring BS information that LTE network is configured before LTE network is left in selection at this time.But if current Serving cell does not configure LTE neighboring cell list, and the cell being previously located once configured LTE neighboring cell list, then by LAI, RAI and Cell ID, whether can tentatively judging the movement of user equipment, in case of movement, then the clothes before meaning The LTE neighboring cell list that business cell is configured may fail, and at this moment can preferably select the networking frequency point column from LTE network Table；If still effective in the LTE neighboring cell list of serving cell configuration before if there is no movements for preliminary judgement, No matter whether previous serving cell is the non-LTE network system being currently located, or currently other under non-LTE system are small Area.

Step S720 measures the adjacent area LTE in LTE cell range to be measured in non-LTE network；

Wherein, it is measured if it is according to the LTE networking frequency point list or LTE frequency point list, according to During LTE networking frequency point list or LTE frequency point list measure, CS Handover switching in case of cross-system or Cell switching in the non-LTE network of person, does not influence the measurement process.

Step S730 saves measurement result, for selecting to intend resident mesh in the service ending of the non-LTE network Mark LTE cell.

It should be noted that the measurement result can also have other purposes, such as assisting web search, this does not go to live in the household of one's in-laws on getting married It states.

For the understanding convenient for those skilled in the art, it is given below and several specifically selects LTE cell range to be measured Example:

If LTE neighboring BS information is the LTE frequency point list and LTE networking frequency point list that LTE network issues, by LTE networking Frequency point list is chosen to be LTE cell range to be measured.

If the LTE frequency point list that the LTE neighboring cell list that LTE neighboring BS information issues for 2G or 3G network, LTE network issue With LTE networking frequency point list, and the network of the 2G for issuing LTE neighboring cell list or 3G network non-present processing business then will The LTE neighboring cell list that the 2G or 3G network issue is chosen to be LTE cell range to be measured or selects LTE networking frequency point list It is set to LTE cell range to be measured.

The 2G for issuing LTE neighboring cell list or the phenomenon that network of 3G network non-present processing business, typically occur in down State in situation: LTE neighboring cell list is not configured in the network of currently processed business, and same during user equipment processing business Switch between multiple cells between a non-LTE network system, it is also possible to be cut between different types of non-LTE network system It changes, user equipment may receive LTE neighboring cell list in cell or network system before this.

If the LTE frequency point column that the LTE neighboring cell list that LTE neighboring BS information issues for 2G or 3G network, LTE network issue Table, and the network of the 2G for issuing LTE neighboring cell list or 3G network non-present processing business, then will be under the 2G or 3G network The LTE neighboring cell list of hair be chosen to be LTE cell range to be measured or by the LTE frequency point list that LTE network issues be chosen to be to Measure LTE cell range.

If the LTE networking frequency point that the LTE neighboring cell list that LTE neighboring BS information issues for 2G or 3G network, LTE network issue List, and the network of the 2G for issuing LTE neighboring cell list or 3G network non-present processing business, then by the 2G or 3G network The LTE neighboring cell list issued is chosen to be LTE cell range to be measured or LTE networking frequency point list is chosen to be LTE to be measured Cell range.
