Description

Network search method and web search device, terminal

Technical field

The present invention relates to wireless communication technology field, in particular to a kind of network search method, a kind of web search Device and a kind of terminal.

Background technology

The communications field enters the 4G epoch, and whole network framework has a very big change compared with 2G/3G, and voice service As the most basic and most important demand of wireless telecommunications, how to realize in 4G, brought not to Virtual network operator and terminal business Small trouble, major chip manufacturer and 3GPP tissues propose different solutions for operator's selection, main bag at this stage Include single-card double-standby scheme（SGLTE/SVLTE）, circuit domain dropping scheme（CSFB）, SRVCC/VOLTE, wherein SVLTE （Simultaneous Voice and LTE, LTE is synchronous with voice network to be supported）Single-card double-standby scheme has no special requirements to network, Network side change is small, it is not necessary to disposes IMS, enjoys Domestic Carriers to favor.

Seamless coverage, or even operator are not reached also for cost in 4G networking initial stage, the 4G network coverages at this stage Consider to take Regional covering in some cities and area, this certainly exists 4G off-grid problems for mobile terminal.

As shown in Figure 1, it is assumed that in Fig. 1（a）In, UE is in 3G and 4G networks double standby or singly treats 4G networks；When UE leaves 4G nets During network overlay area, 4G network off-grids can be caused, so as into Fig. 1（b）Shown situation, that is, it is connected to 2G and 3G nets Network, or when UE leaves 4G and 3G network overlay area, possibly into Fig. 1（c）Shown situation, that is, it is only connected to 2G nets Network, or UE are likely to be at or into Fig. 1（e）The shown region without any mobile network covering, UE off-grids（OOS, out of service）；And when UE is come back under 4G networks, such as Fig. 1（d）Shown, user is it is clearly desirable that 4G nets can be returned quickly Network, but for the consideration to power consumption of terminal, it is clear that UE can not be caused ceaselessly to attempt search and access to 4G networks always Operation.

Therefore, how to avoid UE electricity caused by blindly searching net from wasting, enable to UE to access particular network as early as possible again（Such as 4G networks）, turn into technical problem urgently to be resolved hurrily at present.

The content of the invention

The present invention is based on above mentioned problem, it is proposed that a kind of new technical scheme, can be according to the change in location of terminal Situation, the web search frequency and/or number of terminal can either be controlled, avoiding frequently blindly searching net causes the wave of power consumption of terminal Take, and can enough helps terminal to access particular network as early as possible, helps to lift Consumer's Experience.

In view of this, the present invention proposes a kind of network search method, including：Terminal is from first network off-grid or not yet notes Volume is to the first network；Obtain the real-time position information of the terminal；When determining the end according to the real-time position information When the change in location distance at end is more than or equal to default variable quantity, the terminal performs the search operation to the first network.

In the technical scheme, when change in location caused by terminal is more than or equal to predetermined value, terminal is highly likely to enter/ Reenter the overlay area of first network, then now by performing to the search operation of first network, both added search net into Power, and can, which enough avoids blindness from searching net, causes the power consumption of terminal to increase, and helps to extend the stand-by time of terminal.

In the above-mentioned technical solutions, it is preferable that the real-time position information for obtaining the terminal specifically includes：Pass through the end Satellite positioning module in end, obtain the real-time position information；And/or when the terminal resides at the second network, from this Network side corresponding to second network receives the real-time position information of the terminal.

,, can be by residing in second after terminal is from first network off-grid for multimode terminal in the technical scheme Network, to ensure the continuity of communication.In the second network, by the real-time position information for obtaining terminal, it becomes possible to accurate The change in location situation of terminal is solved, and is started in time to first network there occurs during the change in location of relatively large distance in terminal Search operation.Or the technical scheme of the application is also applied for other scenes, for example terminal is not covering the region of first network During interior start, the second network can be registered to first, and combine the above-mentioned search operation based on change in location, it is ensured that terminal is quick While searching first network, avoid blindly searching net, help to reduce power consumption of terminal.

Wherein, first network and the second network can be the different mobile radio networks of any two, such as Base station under same position, the coverage of first network are likely less than the coverage of the second network.It is more specific and preferred Ground, such as first network can be 4G networks（Such as LTE）, and the second network can be 2G networks（Such as GSM, GPRS, EDGE CDMA1X etc.）Or 3G network（Such as CDMA2000, TD-SCDMA/TD-HSPA, WCDMA/HSPA）.2G/3G networks are because layout Time is early, the network optimization is perfect, so generally its network coverage is than the large and complete face of 4G networks that was laid out later, therefore 4G takes off The situation of net and 2G/3G not off-grid easily occurs in some regions.

For the real-time position information of terminal, the satellite positioning module direct measurement that can be configured by terminal itself, specifically The GPS positioning system such as the U.S., the BEI-DOU position system of China, the GALILEO positioning system in Europe, Russia can be used GLONASS alignment systems etc.；The real-time position information of terminal can also be known by network side and informs the terminal, specifically, can With by the base station under the second network according to the receiving side signal parallactic angle from the terminal or according to the terminal respectively with multiple bases Relation of signal receiving strength between standing etc., determine the real-time position information of the terminal.

In the above-mentioned technical solutions, it is preferable that also include：When the company of the search operation of first network described in the terminal-pair When the continuous frequency of failure is more than or equal to preset times, the terminal stops execution based on the change in location distance to described the The search operation of one network.

In the technical scheme, pass through the statistics to the continuous frequency of failure so that when the continuous frequency of failure is more（For example connect The continuous frequency of failure is more than or equal to preset times）When, show not cover first network interior in a big way.Thus rear In continuous operation, even if serving cell corresponding to terminal and/or adjacent cell change, it will not also perform accordingly to first network Search operation, contribute to terminal to reduce power consumption, extend the stand-by time of terminal.

In the above-mentioned technical solutions, it is preferable that when the continuous failure of the search operation of first network described in the terminal-pair When number is more than or equal to preset times, in addition to：Start timer, and the terminal is initiated after the timer expiry To the search operation of the first network.

In the technical scheme, using the web search mode based on timer, i.e., per after when the timer times out, terminal is held Row, if successful, access first network, otherwise resets timer, to wait the timer again to the search operation of first network After secondary time-out, the search operation to first network is re-executed.

Cell is based on because when the continuous frequency of failure is more, terminal stops performing（Serving cell and/or adjacent cell）Become That changes searches net operation, thus is operated by the above-mentioned web search based on timer so that while power consumption of terminal is reduced, energy Enough promptnesses for ensuring to scan for first network to a certain extent, avoid the covering of user's entrance/return first network Region can not but register for a long time.

In the above-mentioned technical solutions, it is preferable that also include：If the terminal initiated after the timer expiry to institute The search operation failure of first network is stated, then the continuous frequency of failure is subtracted into default value, to be held again by the terminal Search operation to the first network of the row based on the change in location distance.

In the technical scheme, when based on timer search net operation failure when, for searching net frequency based on timer Relatively low situation, can be by changing " the continuous frequency of failure ", such as in order to improve the promptness that terminal accesses first network again The continuous frequency of failure is reduced to less than preset times, so as to make terminal to re-execute once searching based on change in location distance Net operation, the overlong time of timer expiry is avoided waiting for, help to shorten the stand-by period of user.

In the above-mentioned technical solutions, it is preferable that also include：Initiated after the terminal is in the timer expiry to institute When stating the search operation failure of first network, the timer is restarted immediately, or increase the timer according to predetermined manner Timing time simultaneously restarts the timer.

In the technical scheme, by increasing the timing time of timer, it can further reduce terminal and perform to first The frequency of the search operation of network, so as to help to reduce the power consumption of terminal, be advantageous to saving power for terminal, particularly with a wide range of When region without LTE network covering is quickly moved, searching times can be significantly reduced.It is of course also possible to use fixed timing Duration, without being adjusted to timing.

In the above-mentioned technical solutions, it is preferable that when the continuous failure of the search operation of first network described in the terminal-pair When number is more than or equal to preset times, in addition to：When the terminal resides at the second network, if the terminal initiates route Area update is asked or band of position renewal request, then initiates the search operation to the first network.

It is inevitable adjoint due to routing region updating request or the initiation of band of position renewal request in the technical scheme The change in location of terminal, and terminal probably due to the change of the band of position and come back to the overlay area of first network, Thus the search operation accordingly to first network is not blindly to perform, but may be successfully searched first network with larger, Contribute to user's success, rapidly recover to first network, lift Consumer's Experience.

In the above-mentioned technical solutions, it is preferable that also include：If the terminal initiate based on routing region updating request or The search operation to the first network of band of position renewal request fails, then the continuous frequency of failure is subtracted into present count Value, to re-execute the search operation to the first network based on the change in location distance by the terminal.

In the technical scheme, if searching net operation still based on what routing region updating request or band of position renewal were asked Failure, then, can be by changing " the continuous frequency of failure " in order to improve the promptness that terminal accesses first network again, such as will even The continuous frequency of failure is reduced to less than preset times, and once net behaviour is searched based on change in location distance so as to make terminal to re-execute Make, avoid waiting for the overlong time that terminal initiates routing region updating request or band of position renewal request, help to shorten and use The stand-by period at family.

In any of the above-described technical scheme, it is preferable that also include：When data traffic requirement be present in the terminal, and/or The terminal reside at the second network and the terminal change in location distance be less than default variable quantity in the case of, judge institute It is resident when stating terminal corresponding serving cell and/or adjacent cell changing in second network, and/or in the terminal In the case that the change in location of the second network and terminal distance is less than default variable quantity, judge the terminal described the When the changing value that one or more under two networks selectes parameter is more than or equal to default changing value accordingly, it is allowed to the terminal Perform the search operation to the first network；Wherein, the selected parameter includes at least one of or its combination：The end The signal intensity of serving cell corresponding to end and/or adjacent cell, the transmission power intensity of the terminal and/or transmission signal are strong The bit error rate and/or Block Error Rate, the end corresponding to emission delay corresponding to degree, the terminal and/or reception delay, the terminal Signal to noise ratio corresponding to end and/or signal interference ratio.

In the technical scheme, in the second network, because terminal is necessarily connected to neighbouring cell so that pass through understanding To terminal in the second network the situation of change of corresponding serving cell and/or adjacent cell, it becomes possible to directly reflect that terminal exists The change of change in location situation under second network, i.e. serving cell and/or adjacent cell is necessarily due to the change in location of terminal Caused by, and the change in location of relatively large distance most probably occurs for terminal.

When the change in location of relatively large distance occurs for terminal, except the change of serving cell and/or adjacent cell, will also cause The changing value of above-mentioned various selected parameters is larger（Such as larger than or equal to corresponding default changing value）, and therefore terminal is likely to Into/return first network overlay area.So determination by the changing value to above-mentioned selected parameter, you can reflect The change in location situation of terminal, this is determined whether that terminal performs the search operation to first network, can be in certain journey Avoid blindly searching net on degree, help to reduce the power consumption of terminal, be advantageous to saving power for terminal.

Or it can also just perform the search to first network only in the case of it data traffic requirement be present in terminal Operation, so as to both meet the applied mental of user, contribute to recover the connection with first network in time again, and avoid terminal Blindness search net operation.

The invention also provides a kind of web search device, including：Location information acquiring unit, in terminal from first Network off-grid or when having not yet registered to the first network, obtains the real-time position information of the terminal；Change in location judges single Member, for according to the real-time position information, judging whether the change in location distance of the terminal meets to be more than or equal to and presetting Variable quantity；Web search unit, in the case of in judged result to meet, perform the search behaviour to the first network Make.

Embodiment

It is below in conjunction with the accompanying drawings and specific real in order to be more clearly understood that the above objects, features and advantages of the present invention Mode is applied the present invention is further described in detail.It should be noted that in the case where not conflicting, the implementation of the application Feature in example and embodiment can be mutually combined.

Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still, the present invention may be used also To be different from other modes described here using other to implement, therefore, protection scope of the present invention is not by described below Specific embodiment limitation.

Fig. 2 shows the schematic flow sheet of network search method according to an embodiment of the invention.

As shown in Fig. 2 network search method according to an embodiment of the invention, including：

Step 202, terminal from first network off-grid or has not yet registered to the first network；

Step 204, the real-time position information of the terminal is obtained；

Step 206, when the change in location distance that the terminal is determined according to the real-time position information is more than or equal in advance If during variable quantity, the terminal performs the search operation to the first network.

First, acquisition of information

In flow as shown in Figure 2, step 204 relate to the acquisition for " real-time position information ".Specifically, this is obtained Process is taken to use various ways, such as can be in the following way：

1st, terminal obtains

Preferably, the real-time position information for obtaining the terminal specifically includes：Pass through the satellite fix mould in the terminal Block, obtain the real-time position information.

Specifically, it can be configured in terminal and support the GPS positioning system such as the U.S., the BEI-DOU position system of China, Europe The satellite positioning module of the GALILEO positioning system in continent, the GLONASS alignment systems of Russia etc., to obtain the real-time position of terminal Confidence ceases.

2nd, network side obtains

Preferably, the real-time position information for obtaining the terminal specifically includes：When the terminal resides at the second network, Network side corresponding to terminal from second network receives the real-time position information of the terminal.

It should be noted that：, can be by residing in the second network, to ensure to communicate after terminal is from first network off-grid Continuity.In the second network, by the real-time position information for obtaining terminal, it becomes possible to the accurate change in location for understanding terminal Situation, and start the search operation to first network in time there occurs during the change in location of relatively large distance in terminal.Or this The technical scheme of application is also applied for other scenes, for example, terminal do not cover started shooting in the region of first network when, can be first The second network is first registered to, and combines the above-mentioned search operation based on change in location, it is ensured that terminal fast search to first network While, avoid blindly searching net, help to reduce power consumption of terminal.

Specifically, i.e., the real-time position information of terminal is obtained by network side, and the real-time position information is informed into terminal；Should Network side is registered second network of terminal.Network side can obtain the real-time position information of terminal by following manner：

（1）After endpoint registration to the second network, cell provides service as corresponding to some base station.The base station is receiving During the signal of self terminal, the real-time position information of terminal according to the reception azimuth of the signal, can be determined.

（2）, can be in the same time after endpoint registration to the second network（Or the period）Terminal and multiple bases are determined respectively The relation of signal receiving strength between standing, so that it is determined that the real-time position information of the terminal.

2nd, idiographic flow

Above-mentioned technical proposal is described in detail with reference to Fig. 3.Wherein, Fig. 3 shows one according to the present invention The schematic flow sheet that web search is performed based on change in location distance of embodiment.

As shown in figure 3, the flow according to an embodiment of the invention that web search is performed based on change in location distance Including：

Step 302, UE（User equipment, i.e. terminal）From LTE off-grids, and enter LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions.

Specifically, it is illustrated here using LTE as " first network ".

Step 304, UE real-time position information is recorded.

Specifically, the real-time position information can be measured by UE itself；Or if UE resides in the second network, UE is informed after being measured by network side, for example this sentences 2G/3G networks and is illustrated for " the second network ".

Step 306, according to UE real-time position information, judge whether UE change in location distance L meets to be more than or not small In default distance change amount L0.If satisfied, then entering step 308, otherwise continue waiting for.

Specifically, on the one hand, the real-time position information of precedence record is stored with UE；On the other hand, UE is also constantly obtained New real-time position information.Therefore, by the way that the front and rear real-time position information recorded successively is compared, you can determine UE position Put change distance.

Step 308, based in step 306, for the judged result of UE change in location situation, a LTE search is performed Registration.

Specifically, due to UE change in location it is in larger distance when, make it be likely to re-move to LTE coverages, Terminal power caused by blindly searching net can either be thus avoided to be lost, and can enough improves the success rate that UE accesses LTE network again.

Step 310, judge whether LTE search registration operations succeed, if success, into step 312, otherwise return to step 304。

Step 312, UE exits LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions, into normal operating conditions.

Certainly, only illustrated herein by taking " off-grid " scene as an example.In fact, technical scheme is also applied for it His scene.Such as when UE do not cover started shooting in the region of LTE network when（If supporting 2G/3G networks, 2G/ can also be registered to 3G network）, the search to LTE network can also be realized based on flow as shown in Figure 3, so that can either fast search LTE nets Network, and can enough avoid blindly searching net, help to reduce UE power consumption.

3rd, terminal power saving

Preferably, in technical scheme as shown in Figure 2 or Figure 3, the LTE based on change in location distance can be searched for The continuous frequency of failure of operation is counted, i.e., the continuous frequency of failure.When the continuous frequency of failure is more（Such as the continuous frequency of failure More than or equal to preset times）When, show not cover first network interior in a big way.Thus in follow-up operation In, following processing modes can be used：

When the continuous frequency of failure of the search operation of first network described in the terminal-pair is more than or equal to preset times, The terminal stops performing the search operation to the first network based on change in location distance, contributes to terminal to reduce work( Consumption, extend the stand-by time of terminal.

4th, cell change is combined with other technologies means

After stopping to the search operation of first network, terminal-pair LTE network may be influenceed（That is first network）And When access, thus other technologies means can be combined, to solve the drawback.

Embodiment one：Timer

Because when the continuous frequency of failure is more, terminal stops performing the net operation of searching based on change in location distance, thus Operated by the above-mentioned web search based on timer so that, can be true to a certain extent while power consumption of terminal is reduced The promptness scanned for first network is protected, avoids the overlay area of user's entrance/return first network from for a long time can not but Registration.

In the above-mentioned technical solutions, it is preferable that also include：Initiated after the terminal is in the timer expiry to institute When stating the search operation failure of first network, increase the timing time of the timer according to predetermined manner.

Specifically, Fig. 4 A, which are shown, according to an embodiment of the invention is held based on change in location distance and timer The schematic flow sheet of row web search.

As shown in Figure 4 A, it is according to an embodiment of the invention that network is performed based on change in location distance and timer The flow of search includes：

Step 402, UE from LTE off-grids or has not yet registered to LTE network, and enters LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions.

Step 404, UE performs the LTE search registration processes based on change in location distance, referring specifically to Fig. 2 or Fig. 3, herein Repeat no more.

Step 406, continuous frequency of failure N when UE performs LTE search registrations is counted.

Wherein, if continuous frequency of failure N is more than or not less than preset times N1, into step 408, step is otherwise returned to Rapid 404.

Step 408, timer is started, it is assumed that its timing time is Tresearch, specifically, Tresearch time length Degree can be configured as needed.

Step 410, judge whether timer is overtime, if overtime, into step 412, otherwise continue waiting for.

Step 412, UE is controlled to perform a LTE search registration.

Because Tresearch time span is longer than the LTE search registration intervals under default situations, thus contribute to UE Economize on electricity；Meanwhile the LTE search registrations based on timer, can be behind the overlay area of UE entrance/return LTE network, it is ensured that UE Access LTE in time, avoids period of reservation of number long.

Step 414, judge that LTE search registers whether success, if success, into step 416, otherwise into step 418.

Step 416, UE exits LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions, and enters normal operating conditions.

Step 418, the timing time Tresearch of timer numerical value, and return to step 408 are increased.Pass through increase Tresearch numerical value, to reduce the number of LTE search registrations, help to cover in the interior LTE network that is not present in a big way, Or user do not occur relatively large distance it is mobile when, reduce UE power consumptions.The timing length of certain timer can not also adjust, but It is arranged to fixed timing length.

Wherein, process is increased for Tresearch numerical value, can be in the following way：

（1）Threshold value Threshold=n × Tresearch is set, and corresponds to same Threshold, n represents to perform The number of LTE search registrations.

（2）After n LTE search registration, Threshold is increased to original m times（Such as m=2 or other numbers Value）, while still keeping Threshold=n × Tresearch, i.e. Tresearch also increases to original m times.

（3）Until Threshold increases to default maximum of T hreshold_max, then stop adjustment Threshold and Tresearch numerical value.

Certainly, aforesaid way is only used for illustrating；Skilled in the art realises that be, it is clear that its other party can also be used Formula, for example so that the timing time of timer is n × Tresearch, n is the number of LTE search registrations.

As shown in Figure 4 B, on the basis of the technical scheme shown in Fig. 4 A, step 418 '（Corresponding to the step shown in Fig. 4 A 418）In continuous frequency of failure N numerical value can also be adjusted.Specifically, should be by the numerical value of the continuous frequency of failure N Reduce（For example subtract 1）, during causing return to step 406, re-executed due to N ＜ N1 in step 404 based on change in location The LTE search registration processes of distance, so as to which " change in location distance " and " timer " be combined with each other utilization, can either pass through " timer " reduces the UE power consumption searched net frequency, reduce UE, and and can is enough to ensure UE again by " change in location distance " Access LTE promptness.

It should be noted that：

In figure 4b, " when continuous frequency of failure N " is meant that UE is based on change in location distance and performs LTE search registrations Continuous failure number；And when using other counting modes, more technical schemes can also be expanded out.

For example, mistake when will can be registered based on " change in location distance " and " timer " come the LTE search realized Lose number and carry out unified counting, operate and fail as long as performing LTE search registrations, " continuous frequency of failure N " will be caused Change, without distinguishing the triggering factors of LTE search registration operations, help to reduce the complexity of algorithm.Specifically, As " continuous frequency of failure N " while when corresponding to the pass " change in location distance " and " timer " and searching for registration the LTE that realizes The frequency of failure when, the step 418 in Fig. 4 B ' following step in Fig. 4 C can be divided into：

Step 418 ' A, when the LTE search registration behavior failures initiated based on " timer ", continuous frequency of failure N adds 1。

Step 418 ' B, increase the timing time of timer according to predetermined manner, and the continuous frequency of failure is subtracted 2（Or The bigger numerical value of person）, N ＜ N1 are ensured during causing return to step 406, so as to trigger the LTE search based on change in location distance Registration process.The timing length of certain timer can not also adjust, and be arranged to fixed timing length.

Embodiment two：Area update

Fig. 5 A, which are shown, according to an embodiment of the invention performs net based on change in location distance and area update The schematic flow sheet of network search.

As shown in Figure 5A, it is according to an embodiment of the invention that net is performed based on change in location distance and area update The flow of network search includes：

Step 502, UE from LTE off-grids or has not yet registered to LTE network, and enters LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions.

Step 504, UE performs the LTE search registration processes based on change in location distance, referring specifically to Fig. 2 or Fig. 3, herein Repeat no more.

Step 506, continuous frequency of failure N when UE performs LTE search registrations is counted.

Wherein, if continuous frequency of failure N is more than or not less than preset times N1, into step 508, step is otherwise returned to Rapid 504.
