Embodiment
As stated in the Background Art, the method for recognizing and preventing ping-pong reselection between pattern in the prior art is generalized into multimode to lead to When believing in terminal, the cell being exactly currently resident to communication terminal and its all adjacent cells set each self-corresponding gravity treatment timing Device, when cell reselection occurs for communication terminal, starts the corresponding reselection timer in persistent district when corresponding gravity treatment occurs, if Communication terminal is when the reselection timer corresponding cell is returned in gravity treatment again during reselection timer operation, and in cell reselection During comprise at least two kinds of access modules when, then can determine whether out to there occurs the ping-pong reselection from the cell, then improve The cell reselection to other cells reselection conditions, to limit the generation of ping-pong reselection.During cell reselection between judgment model, It is also required to set a reselection timer to every kind of access module, when cell reselection is the cell reselection of cross-module formula, starts small The reselection timer of the corresponding access module of persistent district during area's gravity treatment, if during timer is run, and gravity treatment is returned this and connect Enter pattern, then can determine whether to there occurs the cell reselection between pattern.
But with multimode move the access module type supported increase, it is necessary to the quantity of timer also can be proportional Increase, and simultaneously may the timer quantity of startup optimization also can be a lot, and in fact, wherein most clock is all not The necessary wasting of resources.This can cause very big shadow for the memory source extremely communication terminal of preciousness to systematic function Ring.Moreover, during cell reselection between the recognition mode of prior art, each access module supported communication terminal is also without preferential The differentiation of level, it is thus possible to cause communication terminal to reside in non-optimal access module that optimum performance can not be obtained for a long time.
In order to solve the above problems, technical solution of the present invention provides a kind of knowledge of ping-pong reselection between pattern of communication terminal Not with the method prevented, it is only necessary to set reselection timer to the communication terminal cell portion that successful reselection has been crossed so that timing The quantity of device is reduced a lot, is saved the memory source of communication terminal, is reduced the complexity of identification process, improve pattern Between ping-pong reselection identification and the efficiency that prevents.Meanwhile, the knowledge method for distinguishing of ping-pong reselection between the pattern of technical solution of the present invention will The access module that communication terminal is supported is ranked up according to default priority, is by the higher access mould of priority only in gravity treatment The cell of formula to the relatively low access module of priority cell when, just improve reselection conditions, overcome in the prior art, may lead Communication terminal is caused to reside in for a long time in non-optimal access module, it is impossible to obtain the shortcoming of optimal service.
Further, in a period of time not by the cell of successful reselection again, can also by the cell and its correspondingly Reselection timer delete in the lump, to save the system resource of communication terminal.
In addition, for the cell of gravity treatment no longer occurs in a period of time, the reselection conditions being enhanced can be gradually reduced, Avoid because reselection conditions are excessively harsh so that communication terminal needs the cell reselection being normally carried out not complete.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention Specific implementation be described in detail.
Embodiment one
The flow signal of method for distinguishing is known for ping-pong reselection between the pattern of the communication terminal of the embodiment of the present invention as shown in Figure 1 Figure, including：
Step S11：Record the re-selecting cell table of the communication terminal.The re-selecting cell table includes complete with communication terminal Into cell reselection corresponding to most K cells, wherein K be more than or equal to 2.Specifically, K value is according to communication terminal Complete cell reselection institute time-consuming and the crash time of identification ping-pong reselection determines, be i.e. K, which is equal to, recognizes ping-pong reselection The number of times for the cell reselection that can be completed in crash time.It should be understood that when communication terminal passes through a period long enough Gravity treatment is returned after original cell again afterwards, then is not considered as there occurs ping-pong reselection, this sufficiently long time is exactly the identification The crash time of ping-pong reselection, it can be integrated and determined according to the characteristic of communication terminal and mobile network, general range can be 2.5 Minute was by 3.5 minutes.The crash time of table tennis identification gravity treatment in the present embodiment is equal to 3 minutes.And under normal circumstances, mostly The time span that number communication terminals complete a cell reselection is about 8s, then according to the above-mentioned definition to K values, and K is just etc. In 23.For the ease of record, the order that can complete cell reselection according to communication terminal is recorded successively, for example, communication terminal is opened Machine is normally resident first cell C1, then increases to C1 in the re-selecting cell table；Afterwards in the event of successful reselection to the Two cell C2, then increase to C2 in the re-selecting cell table；The like, it at most can record K cell.If when communication is whole Hold the corresponding cell number of completed cell reselection be more than K when, then can according to first in first out principle, it is small in the gravity treatment The corresponding K cell of the K cell reselection finally completed is recorded in area's table.Each cell can use globally unique cell ID To distinguish.
Step S12：Corresponding first timer is set respectively to each cell in the re-selecting cell table.Wherein first Timer is the timer that communication terminal is used to carry out gravity treatment timing.For example, setting correspondence to the C1 cells in the table of re-selecting cell The first timer TC1, corresponding first timer TC2 is set to C2 cells, K the first timers are at most set.Such as step Described in S11, communication terminal is after any cell reselection is completed, if resident cell is not in the re-selecting cell table, Then the resident cell is increased in the re-selecting cell table, now also this increased cell is set and corresponded to therewith The first timer.It can be seen that, compared with the recognition methods of ping-pong reselection between the pattern of prior art, gravity treatment is used in the present embodiment The number of first timer of timing is up to 23, for multi-mode communication terminal, the timer for recognizing gravity treatment Quantity has considerable reduction, and the system resource of communication terminal is saved to a certain extent, can also improve gravity treatment and recognize The efficiency of journey.
Step S13：If the communication terminal, which is resident gravity treatment, initiates occur cell reselection during cell, start the gravity treatment hair Play corresponding first timer of cell.It can be any cell in the table of re-selecting cell that cell is initiated in the gravity treatment.For example, when logical When letter terminal resides in generation cell reselection in C1, then start TC1, cell C1, which then attaches most importance to, has published cell；When communication terminal into After work(gravity treatment is into C2 and when occurring cell reselection, then start TC2, now C2, which also attaches most importance to, has published cell.That is, every time Cell reselection process can all start first timer, also just corresponded to a gravity treatment and initiated cell, and there may be simultaneously Cell is initiated in multiple gravity treatments.
Step S14：During first timer is run, if the gravity treatment time gravity treatment initiates small to the communication terminal again Cell reselection process area, and the initiation cell by gravity treatment includes cell reselection between pattern at least one times, then will be by institute State gravity treatment and initiate ping-pong reselection between pattern the cell reselection process that sets out of cell is identified as initiating cell by gravity treatment.It is described It is to initiate cell with the gravity treatment corresponding to first timer that cell is initiated in gravity treatment.
Wherein, cell weight between pattern at least one times is included for the cell reselection process the initiation cell by gravity treatment Choosing can use prior art, and a kind of identification process of prior art is：One is all set to the access module that communication terminal is supported Individual reselection timer, when the cell reselection from an access module to another access module occurs for communication terminal, is then opened The reselection timer of the corresponding access module in persistent district during dynamic cell reselection, if during the reselection timer is run, communication The access module is returned in gravity treatment to terminal again, then judges that communication terminal there occurs the cell reselection between pattern.It is to further save System resource, reduction identification complexity and raising systematic function, in the present embodiment, the deterministic process of the cell reselection pattern As shown in Fig. 2 comprising the following steps：
Step S141：The access module rock mechanism sequence supported with communication terminal, the mode sequences have relative First direction and second direction.Specifically, in this step, according to the corresponding pre-set priority of each access module to communication terminal The access module of support is ranked up.Wherein default priority can be set according to user's request or the actual state of network Put, such as it is default priority to select resident priority, or according to searching the sequencing of net after start to be default preferential Level etc..Generally, in order to ensure that communication terminal can obtain optimum performance, the resident priority of selection is as default preferential Level.By taking three mould communication terminals as an example, three kinds of access modules of support are respectively MODE1, MODE2 and MODE3, if communication terminal is stayed More preferable performance can be obtained when staying in MODE1 network, then MODE1 is set to highest priority, is similarly excellent successively The high MODE2 of the first level and minimum MODE3 of priority.After being sorted from high to low by resident priority, mode sequences are just { MODE1, MODE2, MODE3 }.Then, also the mode sequences are defined with relative first direction and second direction.This reality Apply in example, be first direction by the direction of high priority to low priority, such as from MODE1 to MODE2 or MODE3, from MODE2 To MODE3 direction；So, the direction from low priority to high priority is just second direction, such as from MODE3 to MODE1 Or MODE2, the direction from MODE2 to MODE1.When it is implemented, when not being resident priority requirement, can also be to each access Pattern is randomly ordered.After randomly ordered, it is first direction that can select either direction, is second in the opposite direction with first party Direction.
Step S142：Corresponding second is set to each access module in addition to last access module on first direction Timer.Corresponding second timer TP1 and TP2 are set respectively to MODE1 and MODE2, MODE3 is then not provided with.Wherein, Second timer is for carrying out gravity treatment timing to each access module.
Step S143：Connect if the communication terminal initiates access module from the gravity treatment to any on the first direction Enter pattern and carry out cell reselection, then start the gravity treatment and initiate corresponding second timer of cell.Wherein, access mould is initiated in gravity treatment Formula can be understood as the corresponding access module in communication terminal institute persistent district when any gravity treatment occurs.Meanwhile, only when small When area's gravity treatment is on the first direction, it can just start gravity treatment and initiate corresponding second timer of access module.I.e. when communication is whole When end carries out cell reselection from MODE1 to MODE2, then it is considered that MODE1 attaches most importance to and published access module, start simultaneously The corresponding TP1 of MODE1.It is activated it should be understood that might have multiple timers, that is to say, that the same time might have many Access module is initiated in individual gravity treatment.Such as, when communication terminal is resided in MODE1 cell, if there occurs from MODE1 to MODE2 Gravity treatment when, just start MODE1 corresponding TP1, MODE1 and just turn into gravity treatment and initiate access module；Then communication terminal occurs again Gravity treatment from MODE2 to MODE3, now starts TP2 again, and MODE2 also becomes gravity treatment and initiates access module.
It can be seen that, in the present embodiment, the restrictive condition of the second timer of startup, which is attached most importance to, publishes life in a first direction, therefore The deterministic process of cell reselection is compared between middle judgment model compared with prior art, and the probability that the second timer is activated is reduced Half.In combination with step S142, timer quantity has also been reduced, and the cell reselection being so greatly lowered between pattern is sentenced Disconnected process runs the load caused to system due to timer, improves the efficiency of judgement.
Have already mentioned above, the same time may have the second meter that access module and startup optimization are initiated in multiple gravity treatments When device., in the specific implementation, can also be to meeting the gravity treatment access module of stop condition in order to further save system resource Corresponding second timer is out of service, the stop condition be the communication terminal from the gravity treatment initiate access module to Any access module on the first direction cell reselection failure, or from any access module to the first direction on The gravity treatment initiate access module carry out cell reselection success.Such as, TP2 run during communication terminal there occurs from MODE1 to MODE2 gravity treatment, then can stop TP2 operations.In addition, when the run time of the second timer is more than second and preset Between when, can also stop, i.e., time-out stop.Such as, just stop after TP1 timing reaches the second preset time.Wherein, second preset Time carries out the time-consuming of cell reselection between corresponding access module and other access modules by the communication terminal and adds one Fixed idle waiting time determines that general span is 30~180 seconds, and specific value can be according to the type of access module And the aggregation of data of on-the-spot test is determined.Such as when MODE2 is WCDMA, the second preset time can be set as 60 seconds.
Step S144：During the operation of second timer, if the communication terminal is from any access module to institute State the gravity treatment in second direction and initiate the cell reselection success that access module is carried out, then judge the cell weight between emergence pattern Choosing.I.e. during the corresponding second timer operation of access module is initiated in a certain gravity treatment, communication terminal is less than this from priority Gravity treatment initiate access module access module successful reselection to the gravity treatment initiate access module, be considered as communication terminal there occurs from The cell reselection between the pattern that access module sets out is initiated in gravity treatment.Such as, when during TP1 is run, communication terminal by MODE2 or Person MODE3 reselects to MODE1, then can be identified as reuse adoption process from the cell reselection between MODE1 pattern；Compare again Such as, if during TP2 is run, communication terminal reselects to MODE2 by MODE3, then can be identified as gravity treatment from MODE2's Cell reselection between pattern.
It should be understood that communication terminal must start first timer in cell reselection of every completion, but by In the Rule of judgment for not being cell reselection between each cell reselection meets pattern described in step S141 to step S144, therefore not It is that each cell reselection can all start second timer.As long as but during the first timer is run, working as communication terminal Gravity treatment returns the corresponding gravity treatment of first timer and initiates cell again, and there occurs the cell weight between pattern above-mentioned at least one times Choosing, then may determine that communication terminal there occurs ping-pong reselection between the pattern occurred from gravity treatment initiation cell.So far, just complete logical The identification of ping-pong reselection between the pattern of letter terminal.
In other embodiments, in order to further save the memory source of communication terminal, run time can also be deleted More than the first timer of the first preset time, while the first timer for being more than the first preset time with run time is corresponding Cell deleted from the re-selecting cell table, to save the memory cost of communication terminal.Wherein, the first preset time can be with base Determined in the attribute of itself of its corresponding cell, such as the default priority of the access module according to where the cell come It is determined that.For example, when communication terminal there occurs from ping-pong reselection between the pattern of C1 cells, if the corresponding access module of C1 cells The MODE1 of highest priority, then the first preset time can set it is relatively long；If the corresponding access module of C1 cells is excellent The minimum MODE3 of first level, then the first preset time can set it is relatively short.Generally, the model of the first preset time Enclose for 30 to 180 seconds.
It can be seen that, compared with prior art, between the pattern of the embodiment of the present invention in the recognition methods of ping-pong reselection, for carrying out The first timer and the quantity of the second timer and its startup probability that gravity treatment judges all have been reduced so that rattled between pattern The identification process of gravity treatment is easier, easily operated, and saves system resource, improves the efficiency of identification.

Step S22：The communication terminal is improved to be wanted from gravity treatment initiation cell to other cells progress cell reselection Seek the reselection conditions of satisfaction.Communication terminal carry out cell reselection when, the condition typically to be met be Target cell signal intensity/ Quality is better than current area more than certain time, wherein just containing two conditions, first condition is the signal of Target cell Intensity/quality will reach requirement, i.e., described communication terminal gravity treatment to cell signal strength/quality threshold required by other cells Value, second condition be Target cell signal strength/quality meet first condition after its duration also to reach will Ask, i.e., described communication terminal is measured required by cell signal strength/quality of other cells when being resident the gravity treatment initiation cell Time gate limit value.Can be to cause the difficulty of cell reselection to increase, so as to limit mould it should be understood that improving the two conditions The continuation of ping-pong reselection occurs between formula.Judge that communication terminal there occurs the mould from cell C1 by step S21 for example, working as Ping-pong reselection between formula, then with regard to improving cell signal strength/quality required by cell C1 to other cells progress cell reselection Threshold value, and communication terminal reside in the time for cell signal strength/quality requirement that other cells are measured when in C1 cells Threshold value, occurs with the continuation of ping-pong reselection between unrestricted model.Specifically, cell signal strength/quality threshold of the requirement The raising stepping of value and desired time gate limit value can be set, such as be set to 9dB and 5s.
In other embodiments, reselection conditions can also be only comprising small required by described other cells of communication terminal gravity treatment Area's signal strength/quality threshold value or the communication terminal measure the cell of other cells when being resident the gravity treatment initiation cell Signal strength/quality required time threshold value, can equally increase communication terminal and initiate cell to other cells from gravity treatment The difficulty of gravity treatment, thus between unrestricted model ping-pong reselection generation.
It should be noted that can all improve the reselection conditions after ping-pong reselection between each pattern of communication terminal.And from Ping-pong reselection is possible to repeat to occur between the pattern set out of cell is initiated in gravity treatment, thus reselection conditions can with gravity treatment frequency by Step is improved, that is to say, that between easier emergence pattern between the cell of ping-pong reselection, gravity treatment thresholding will be stricter.So also comply with The demand of actual use, it is to avoid the frequent generation of ping-pong reselection between pattern.
To sum up, compared with prior art, the method that ping-pong reselection is prevented between the pattern for the communication terminal that the present embodiment is provided, Can be communication terminal section because the quantity of the setting of timer and the probability of startup timer operation have a considerable amount of reductions About system resource, improving communication terminal prevents the efficiency of ping-pong reselection between pattern.
Further, because in the identification process of the cell reselection between pattern, mode sequences are each right according to access module The pre-set priority answered is ranked up so that it is the access module from higher priority that the raising of reselection conditions, which is only limited in gravity treatment, Onto the direction of the access module of lower priority, communication terminal is resided in for a long time caused by prior art can be overcome possible Shortcoming in the network of non-optimal access module, can guarantee that user obtains optimal service, improves the performance and use of communication terminal The Experience Degree at family.
Embodiment three
As shown in figure 4, the flow for the method that ping-pong reselection is prevented between the pattern of the communication terminal of the embodiment of the present invention is shown It is intended to, including：
Step S31：Record the recovery re-selecting cell table of the communication terminal.Recovery re-selecting cell table includes most M Individual recovery re-selecting cell, wherein M=2K, the recovery re-selecting cell refers to occur between the pattern reselection conditions after ping-pong reselection The cell being enhanced.M can be determined according to K value and the experience actually arranged net, and typically take twice of K, i.e., when K values For 23 when, M is equal to 46.Specifically, there occurs when residing in cell C1 after communication terminal start after the ping-pong reselection between pattern, The reselection conditions from cell C1 to other cells are improved, C1 just to recover re-selecting cell, should increase to the recovery gravity treatment small In area's table；There occurs the ping-pong reselection between pattern when communication terminal resides in cell C2 afterwards, and improve cell C2 to its The reselection conditions of his cell, now C2 is also recovery re-selecting cell, should be increased in the table of the recovery re-selecting cell；With such Push away, until recording most M recovery re-selecting cells.It is similar with the re-selecting cell table in the embodiment of the present invention one, work as communication Terminal recover re-selecting cell table in recovery re-selecting cell number be more than M when, then can according to first in first out principle, described Recover to record the cell that last M there occurs that ping-pong reselection and reselection conditions are enhanced between the pattern in the table of re-selecting cell. During record, each cell is distinguished with globally unique cell ID.
Step S32：Corresponding 3rd timer is set respectively to each cell in the table of the recovery re-selecting cell.It is described 3rd timer is to initiate cell to the reselection conditions of other cell reselections for recovering gravity treatment.For example, being set to cell C1 Corresponding 3rd timer TR1, corresponding 3rd timer TR2 is set for cell C2, can have up to M the 3rd timing Device.Then step S33 is performed.
Step S33：Rattled between identifying that the communication terminal there occurs the pattern initiating cell by the gravity treatment After gravity treatment, the weight that the communication terminal is met required by cell to other cells progress cell reselection is initiated in the gravity treatment is improved Condition is selected, and starts the gravity treatment and initiates corresponding 3rd timer of cell.It ought identify between cell C1 pattern After ping-pong reselection, the reselection conditions from cell C1 gravity treatments to other cells are just improved, and start corresponding TR1.Specific identification Process refers to the embodiment of the present invention one, repeats no more.
Step S34：If the run time that corresponding 3rd timer of cell is initiated in the gravity treatment is more than the 3rd preset time, Then reduce the reselection conditions that the communication terminal is met as required by cell reselection to other cells is initiated in the gravity treatment.Wherein institute The time-consuming determination that the 3rd preset time carries out cell reselection based on the communication terminal is stated, general span is 30 to 180 seconds, Specific value can be determined according to the aggregation of data of on-the-spot test.Such as to when MODE2 be WCDMA when, the 3rd preset time It can be set as 70 seconds.The reselection conditions include the cell required by gravity treatment initiation cell to other cells progress cell reselection Signal strength/quality threshold value, and communication terminal reside in gravity treatment and initiate to measure the cell signal of other cells when in cell The time gate limit value of intensity/quality requirement.If in other embodiments, improve only in step S33 in two reselection conditions One, then it is corresponding also to reduce this reselection conditions.Specifically, the increasing of expired times can be run according to the 3rd timer Plus the reselection conditions are gradually reduced, until reselection conditions are recovered between the pattern for initiating access module from gravity treatment to rattle The unrelated initial condition of gravity treatment；Reselection conditions disposably can also be reduced to the pattern with initiating access module from gravity treatment Between the unrelated initial condition of ping-pong reselection.Wherein, when the 3rd timer run time is more than corresponding three preset time Out of service and restart, the expired times refer to number of times of the 3rd timer run time more than the 3rd preset time. When selection is gradually reduced, reduction stepping could be arranged to as improving stepping, might be less that raising stepping, such as by institute The reduction stepping for stating the cell signal strength/quality threshold and desired time gate limit value of requirement is respectively set to 3dB and 3s.
In addition, may repeat to occur from ping-pong reselection between the pattern of gravity treatment initiation cell, when what is again occurred Ping-pong reselection between pattern is during the corresponding 3rd timer operation of cell is initiated in gravity treatment, then to need restarting corresponding 3rd timer, that is, restart timing after recovering the 3rd timer reset condition.
To sum up, the method that ping-pong reselection is prevented between the pattern for the communication terminal that the present embodiment is provided, due to setting for timer The quantity and the probability of startup timer operation put have a considerable amount of reductions, can save system resource for communication terminal, carry High communication terminal prevents the efficiency of ping-pong reselection between pattern.
Further, because in the identification process of the cell reselection between pattern, mode sequences are each right according to access module The pre-set priority answered is ranked up so that it is the access module from higher priority that the raising of reselection conditions, which is only limited in gravity treatment, Onto the direction of the access module of lower priority, communication terminal is resided in for a long time caused by prior art can be overcome possible Shortcoming in the network of non-optimal access module, can guarantee that user obtains optimal service, improves the performance and use of communication terminal The Experience Degree at family.
Further, do not occur again within a period of time from ping-pong reselection between the pattern of gravity treatment initiation cell Afterwards, the reselection conditions progressively can be decreased up into recovery original value, or gravity treatment thresholding is once reduced to original value, so Avoid the reselection conditions during normal use and be raised to excessively strict degree, and cause the net in current area Communication terminal can not be switched in the cell that other can be used during network environment less stable, further perfect communication terminal Prevent the strategy of ping-pong reselection between pattern.
