Specific implementation mode

To make the above purposes, features and advantages of the invention more obvious and understandable, below in conjunction with the accompanying drawings to the present invention Specific implementation mode be described in detail.Detail is elaborated in the following description in order to fully understand the present invention.But It is the present invention with a variety of to implement different from other manner described here, those skilled in the art can be without prejudice to originally Similar popularization is done in the case of invention intension.Therefore the present invention is not limited by following public specific implementation mode.

Inventor has found that there are some to lack from the mode of 2G/3G networks return LTE network for user equipment in the prior art 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 networks are first resided in, and carry out LTE Gravity treatment is to LTE network after the measurement of network and evaluation process.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 networks Message（Such as RRC Connection Release message or Channel Release message）Middle carrying is redirected to LTE The target information of network, it is therefore desirable to which the network side equipment in 2G/3G networks supports the mode, is needed thus to existing 2G/3G networks are upgraded, and the increase of cost and the waste of resource are inevitably resulted in.Also, upgrade of network is typically 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 networks of LTE network.

In addition, inventor also found, in quick echo plex mode in the prior art, when the correlation that 2G/3G networks issue 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, and the quick return course indicated by network is caused to fail.

This failure is inevitable in some cases, for example, 2G/3G networks are to user device configuration LTE nets 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 signals are enough By force, report measurement results when 2G/3G network signals are 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 informations that 2G/3G networks are configured（Such as in 3G In network, the target cell information list that is configured by Redirection info cells）It is not based on user equipment pair The measurement result of LTE network, then often configuration error or invalid target LTE cells 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 that user equipment, which is resident to LTE network,.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 networks issue It is 2G/3G networks, user equipment will switch to the 2G/3G networks 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 networks from LTE network by CSFB modes Situation.Since user equipment is fallen after rise from LTE network, then at the end of circuit domain business, returning to LTE network will more manage Think.But the quick return redirection target that 2G networks are 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 networks do 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 networks think 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 Technique 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 S110, user equipment are fallen after rise from LTE network to non-LTE network；

In present specification, non-LTE network includes 2G/3G networks.Here, the 2G/3G networks should make amplified interpretation, packet Include usually said 2G communication systems, 2.5G communication systems, 2.75G communication systems and 3G communication systems, 3.5G communication systems, 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, in addition to roaming and gravity treatment between cross-system under normal standby mode, user equipment is resident from LTE network May be in order to realize circuit domain business in non-LTE network, such as speech business, supplementary service, positioning service to non-LTE network Deng.In such cases, CSFB modes may be used to realize.

Specifically, user equipment falls back to GSM network from LTE network, can pass through RRC Connection Release With redirection message or RRC Connection Release with redirection with SIBs disappear The modes such as breath are realized.

User equipment falls back to TD-SCDMA network from LTE network, can pass through RRC Connection Release With redirection message, RRC Connection Release withredirection with SIBs message or Person PS Handover（Packet domain switches）Etc. modes realize.

User equipment falls back to WCDMA networks from LTE network, and side identical with TD-SCDMA network is fallen back to may be used Formula can also use DMCR（Deferred Measurement Control Reading delay and read to measure 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 Can also by UE control gravity treatment, Cell Change Order（Cell Change Order, i.e. CCO）, network-control gravity treatment etc. Mode falls back to 2G/3G networks.

Certainly, user equipment, which switches from LTE network or is resident the business to be carried out to non-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 S120, during non-LTE network, user equipment carries out LTE nearby region measurements, to obtain LTE nearby region measurement knots Fruit；

In general, the business that user equipment is carried out in non-LTE network is circuit domain business.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 specifications defined in 3GPP, " MeasObjectEUTRA " cell describes The adjacent cell information list measured is needed in the LTE system of the be allocated to user equipment of LTE network.In addition, the hair of the present invention A person of good sense proposes that LTE network can also configure LTE networking frequency point lists and be issued to user equipment.

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

The LTE networkings frequency point list generally includes the frequency point information needed for networking and Black Cell lists.

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

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 lists be not configured.For example, in the technical specification defined in 3GPP, " E-UTRA Frequency list " cells and " E-UTRA frequency and priority info list " cell describe 3G systems System can be used for being allocated to the LTE neighbor cell lists of user equipment；" E-UTRAN Parameters Description " believes Member describes the LTE neighbor cell lists that 2G systems can be used for being allocated to user equipment.Furthermore, it is necessary to explanation, in non-LTE 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, all may Configured with LTE neighboring cell lists, it is also possible to LTE neighboring cell lists all be not configured, or at least one is configured with LTE neighboring cell lists.

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

It should be noted that the LTE nearby region measurements can be carried out with user equipment in the business of non-LTE network carries out, Can also be 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 measurements 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, speech business 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 asked 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 Flow, user equipment can receive the RRC Connection Release message that network issues（Under 3G network）Or Channel Release message（Under 2G networks）Or Rejection message, and these message may carry and be redirected to LTE network Target cell information list.

And for due to service ending caused 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 due to only existing the signal of the LTE network or LTE network originals such as more preferably Cause needs in the case of reselecting to LTE network, and 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 of 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 informations of directed information or according to network side instruction return LTE network procedure failure in the case of.

For the step S120 LTE nearby region measurements obtained as a result, user equipment can according to all nearby region measurements as a result, Resident target LTE cells are 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 attempts LTE cells successively；For another example, power threshold is set, is selected in LTE nearby region measurement results Measured value is more than that the LTE cells of power threshold are 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 Receiving Power, reference 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 results LTE cells, then without being resident to the trial of LTE network.

Or if there is no the LTE cells that measured value is more than power threshold in LTE nearby region measurement results, carry out LTE The normal flows such as search, measurement, the PLMN selections of network, to attempt to be resident to LTE network.Wherein, the LTE network is searched The processes such as rope, measurement, PLMN selections may be used mode defined in prior art specification and carry out.

The mode that user equipment is actively resident LTE network can be selected with actual conditions as needed, for example, can To be asked to target LTE cells initiating updating of tracking area (Tracking Area Update, be abbreviated as TAU) using user equipment It asks, the modes such as cell update message or location area updating message；User equipment executes the PLMN of LTE network（Public Land Mobile Network, public land mobile network）Selection is registered in LTE network, is adhered to, the agreements institute such as cell selection Defined process.

The advantageous 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 either 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, includes according to described in being obtained in step S120 LTE nearby region measurement results determine target LTE cells, attempt resident.

In addition, in other embodiments, after user equipment can also be included in the service ending of non-LTE network, carrying out The normal flow such as the search, measurement of LTE network defined in prior art specification, PLMN selections 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 measurements result, it is also possible to which survey can not be selected according to LTE nearby region measurements result by being happened at In the case of magnitude is more than the target LTE cells of RSRP/RSRQ thresholdings.

That is, if during non-LTE network, user equipment, which is got, can be used in independently determining that target LTE is small The LTE network information in area（The result searched for including the LTE nearby region measurements result or the LTE network）, in non-LTE network Service ending after or other need 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 in present specification, described includes that user equipment is returned from LTE network during non-LTE network Non- LTE network is dropped down onto, during being not yet successfully resident to before LTE network.

The business of the non-LTE network, including circuit domain business and/or packet switch domain service；The mode of end is to receive The message of instruction service ending from non-LTE network, or be due to service terminal caused by link terminal；

The message of the instruction service ending is different according to the type of non-LTE network and there are many different forms of expression.

For example, when user winding-up in 2G networks, the Channel from 2G network sides can be received Release message.

For another example, it when user's winding-up in 3G network, can receive from 3G network side RRC Connection Release message.

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

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

In present embodiment, the LTE neighboring BS information that user equipment preserves may include the LTE frequency point row that LTE network issues The LTE neighboring cell lists of table and/or LTE networking frequency point lists, and/or the configuration of non-LTE network.The LTE frequency point row that LTE network issues Table is usually described in " MeasObjectEUTRA " cell；The LTE neighboring cell lists of non-LTE network configuration, usually in " E-UTRA Frequency list " cells and " E-UTRA frequency and priority info list " cell, or " E-UTRAN Described in Parameters Description " cells.The LTE networking frequency point lists that LTE network issues, the LTE networkings frequency Point list, not described in existing technical specification.

In disclosed LTE networking frequency point lists, the range of frequency point or LTE cells is more than Neighboring cell list described in " MeasObjectEUTRA " cell.Neighboring cell list described in " MeasObjectEUTRA " cell, The list of neighboring community typically on the be located at current service cell geographical location of user equipment；And networking list may be then 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 more than in " MeasObjectEUTRA " cell The neighboring cell list of description.Networking list is usually sent to user equipment in a broadcast manner by the broadcast channel of LTE network.

The selection rule of LTE cells 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 cells 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, when LTE neighboring BS information includes at least two class LTE neighboring BS information, newest one kind LTE neighboring BS information is selected It is set to LTE cell ranges to be measured；Or effective and newest one kind LTE neighboring BS information is chosen to be LTE cells model to be measured It encloses.Alternatively, effective LTE neighboring BS information is chosen to be LTE cell ranges 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 ranges 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 are cell marks 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 do not change, then it is assumed that the LTE that LTE neighboring cell lists that 2G or 3G network issue, LTE network issue Frequency point list and LTE networking frequency point lists are effective；

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

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

Wherein, in processing circuit domain when the situation of change of LAI, RAI and Cell ID refers to the business progress of 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 are switched to the CellID of 3G from the Cell ID of 2G, and such variation should not be at any time used for as judgement The validity of LTE neighboring BS information.Due to the fact that the relationship of the adjacent areas 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 systems, has occurred in user equipment, then usually says Bright, enough position movements have occurred in user equipment, then the adjacent areas 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 lists, 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 lists configured by non-LTE network.But in non-LTE nets 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 areas LTE may may not also be configured List.In general, whenever, it is believed that the LTE neighboring cell lists that this current service cell is configured are 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 lists, and the cell being previously located once configured LTE neighboring cell lists, 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 lists that business cell is configured may fail, and at this moment can preferably select the networking frequency point row for coming from LTE network Table；If still effective in the LTE neighboring cell lists of serving cell configuration before if preliminary judge not move, No matter before serving cell whether be the non-LTE network system being currently located, or under current non-LTE system other are small Area.

Step S720 measures the adjacent areas LTE in LTE cell ranges to be measured in non-LTE network；

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

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

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 ease of the understanding of those skilled in the art, it is given below and several specifically selects LTE cell ranges to be measured Example：
