Embodiment
As stated in the Background Art, with the development of multi-mode mobile communication technology, the cell reselection specification between multimode network
It has been be gradually improved that, but because the complexity and GSM of multimode network and the planning of dis environment lower network are intrinsic
Radio characteristics, multimode terminal easily occurs and ping-pong reselection be present between multiple different access modules.And the danger of ping-pong reselection
Evil is, user can be caused can not to carry out regular traffic for a long time, while for communication terminal, due to the table tennis weight of more intermodes
Choosing is all the time along with the conversion of access module, it is necessary to expend many system resources.
Prior art has been achieved with preventing ping-pong reselection between dual-mode terminal pattern.If this method is promoted the use of whole to multimode
When end prevents ping-pong reselection between pattern, it is disadvantage is that set a clock to each access module, complex operation, and
The same time might have multiple clock timings, and wherein most clock is the nonsensical wasting of resources.
Further, since whole process does not involve the priority of access module, communication terminal may be caused to stay for a long time
Stay in the network of non-optimal access module and the problem of user actually uses demand can not be met.For example support GSM/WCDMA
Bimodulus or multi-mode communication terminal, there occurs the cell reselection from GSM to WCDMA, then GSM is returned in gravity treatment again, according to existing
The technology for preventing ping-pong reselection, communication terminal will improve GSM to WCDMA reselection conditions, be resident so that communication terminal is stable
In GSM network, the generation of ping-pong reselection is prevented.If during the more preference WCDMA in actual use of the communication terminal, communication
Terminal will be unable to reach optimum performance because of GSM network is resided in for a long time, can not also meet the use demand of user.
To solve the above problems, technical solution of the present invention provide between a kind of pattern of communication terminal ping-pong reselection identification and
The method prevented, as shown in figure 1, including：
Step S1：The access module rock mechanism sequence supported with the communication terminal, the mode sequences have relative
First direction and second direction；
Step S2：Each access module in addition to last a kind of access module on the first direction is set respectively correspondingly
The first timer；
Step S3：If the communication terminal initiates access module to any access module on the first direction from gravity treatment
Cell reselection is carried out, then starts the gravity treatment and initiates the first timer corresponding to access module；
Step S4：During the operation of first timer, if the communication terminal is from any access module to described
The cell reselection success that access module is carried out is initiated in the gravity treatment in second direction, then by the communication terminal by the gravity treatment
Table tennis is heavy between initiating the pattern the cell reselection process that access module sets out is identified as initiating access module by the gravity treatment
Choosing；
Step S5：Improve the communication terminal access module is initiated from the gravity treatment and connect to any on the first direction
Enter pattern and carry out the required reselection conditions met of cell reselection.
Compared with prior art, the ping-pong reselection identification for the communication terminal that technical solution of the present invention provides and the side prevented
Method, clock need not be set to one of access module, and just start clock when gravity treatment occurs over just first direction, when
The quantity of clock and the probability of startup clock all reduce, and so save the resource of communication terminal, reduce the complexity of operation,
Improve identification and prevent the efficiency of ping-pong reselection.
Further, when mode sequences priority ranking default according to each access module, technical solution of the present invention carries
The ping-pong reselection prevention method of the communication terminal of confession, moreover it is possible to overcome in the prior art, may cause for a long time to stay communication terminal
Stay in the network of low priority, the shortcomings that high-quality service can not be obtained.
In addition, the method that ping-pong reselection prevents between the pattern for the communication terminal that technical solution of the present invention provides, moreover it is possible to not
Occur progressively to recover the gravity treatment thresholding that is enhanced when ping-pong reselection, avoid gravity treatment thresholding and remain high and made for subsequent reselection
Into adverse effect.
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 embodiment be described in detail.
Embodiment one
Ping-pong reselection knows method for distinguishing between present embodiments providing a kind of pattern of communication terminal, wherein the communication terminal
Two or more access module is supported, as shown in Fig. 2 including：
Step S21：The access module rock mechanism sequence supported with the communication terminal, the mode sequences have relative
First direction and second direction.The present embodiment is by taking three mould communication terminals as an example.
Specifically, in the present embodiment, communication terminal support is connect according to pre-set priority corresponding to each access module
Enter pattern to be ranked up.Wherein default priority can be set according to the actual state of user's request or network, such as
The resident priority of selection be default priority, or according to the sequencing of net is searched after start is default priority etc..One
As in the case of, in order to ensure that communication terminal can obtain optimum performance, select resident priority as default priority.This implementation
Three kinds of access modules that three mould communication terminals in example are supported are respectively MODE1, MODE2 and MODE3, if communication terminal resides in
More preferable performance can be obtained during MODE1 network, then MODE1 is arranged to highest priority, is similarly priority successively
The secondary high MODE2 and minimum MODE3 of priority.After being sorted from high to low by resident priority, mode sequences just for MODE1,
MODE2, MODE3 }.
Then, relative first direction and second direction also are defined to the mode sequences., will in the present embodiment
High priority to the direction of low priority be first direction, 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, for example, from MODE3 to MODE1 or MODE2, from
MODE2 to MODE1 direction.
In other embodiments, can also be randomly ordered to each access module when not resident priority requirement.At random
After sequence, either direction can be selected as first direction, be second direction in the opposite direction with first party.
Step S22：Each access module in addition to last a kind of access module on the first direction is set respectively pair
The first timer answered, i.e., corresponding first timer TP1 and TP2 is set respectively to MODE1 and MODE2, MODE3 is not set then
Put.Wherein, the first timer is for carrying out gravity treatment timing to each access module.Then step S23 is performed.
Step S23：If the communication terminal initiates access module to any access mould on the first direction from gravity treatment
Formula carries out cell reselection, then starts the gravity treatment and initiate the first timer corresponding to access module.Wherein, access mould is initiated in gravity treatment
Formula can be understood as access module corresponding to 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 the first timer corresponding to 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
TP1 corresponding to MODE1.It is activated it should be understood that might have multiple timers, that is to say, that the same time might have more
Access module is initiated in individual gravity treatment.For example communication terminal is when residing in MODE1 cell, if there occurs from MODE1 to MODE2
Gravity treatment when, just start MODE1 corresponding to TP1, MODE1 just turn into gravity treatment 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.
Due to start the first timer condition be restricted to gravity treatment occur in a first direction, therefore with prior art phase
Than the probability that the first timer is activated reduces half.In combination with step S22, timer quantity has also been reduced, so
Ping-pong reselection identification process is greatly lowered because timer runs the load to caused by system, improves the efficiency of identification.
Have already mentioned above, the same time may have the first meter that access module and startup optimization are initiated in multiple gravity treatments
When device.In order to further save system resource, in other embodiments, mould can also be accessed to meeting the gravity treatment of stop condition
The first timer is out of service corresponding to formula, and the stop condition is that the communication terminal initiates access module by the gravity treatment
Fail to the cell reselection of any access module on the first direction, 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 it can stop TP2 operations.In addition, when the run time of the first timer is more than first and preset
Between when, can also stop, i.e., time-out stop.For example just stop TP1 after TP1 timing reaches the first preset time.Wherein, first
Preset time carries out the time-consuming of cell reselection between corresponding access module and other access modules by the communication terminal and added
Upper certain idle waiting time determines that general span is 30~180 seconds, and specific value can be according to access module
The aggregation of data of type and Practical on-site test determines.Such as when MODE2 is WCDMA, its corresponding first preset time
It can be set as 60 seconds.
Step S24：During the operation of first timer, if the communication terminal is from any access module to described
The cell reselection success that access module is carried out is initiated in the gravity treatment in second direction, then by the communication terminal by the gravity treatment
Table tennis is heavy between initiating the pattern the cell reselection process that access module sets out is identified as initiating access module by the gravity treatment
Choosing.I.e. during the first timer operation corresponding to access module is initiated in a certain gravity treatment, communication terminal is less than this from priority
Access module is initiated in access module successful reselection to gravity treatment that access module is initiated in gravity treatment, and being considered as communication terminal, there occurs mould
Ping-pong reselection between formula, and to initiate ping-pong reselection between the pattern of access module from the gravity treatment.Such as when in the TP1 runtimes
Between, communication terminal reselects to MODE1 by MODE2 or MODE3, then reuse adoption process can be identified as to the mould from MODE1
Ping-pong reselection between formula；For another example, if during TP2 is run, communication terminal reselects to MODE2 by MODE3, then can know gravity treatment
Wei not be from ping-pong reselection between MODE2 pattern.
To sum up, compared with prior art, ping-pong reselection knows method for distinguishing between the pattern for the communication terminal that the present embodiment provides,
Because the quantity of the setting of timer and the probability that starts timer operation have a considerable amount of reductions, it can substantially reduce and be
System load, improves recognition efficiency.
Embodiment two
The present embodiment provides the method that ping-pong reselection between a kind of pattern of communication terminal prevents, as shown in figure 3, bag
Include：
Step S31：Identify from ping-pong reselection between the pattern of gravity treatment initiation access module.Specific identification process, can
With reference to the embodiment of the present invention one, repeat no more.
Step S32：Improve communication terminal and access module is initiated to any access module progress on first direction from gravity treatment
The required reselection conditions met of cell reselection.When communication terminal carries out cell reselection, the condition typically to be met is that target is small
The signal strength/quality in area is better than current area and exceedes certain time, wherein just containing two conditions, first is that target is small
The signal strength/quality in area will reach requirement, i.e., described communication terminal gravity treatment to any access module on the first direction
Required cell signal strength/quality threshold, second is that to reach requirement lasting for the signal strength/quality of Target cell
Time will reach requirement, i.e., described communication terminal measures appointing on the first direction when being resident the gravity treatment initiation access module
The cell signal strength of one access module/quality required time threshold value.Judge communication eventually by step 31 for example, working as
There occurs from ping-pong reselection between MODE2 pattern at end, then required by just improving MODE2 to MODE3 progress cell reselections
MODE3 cell signal strength/quality threshold, and communication terminal resides in and MODE3 measured when in MODE2 cell
The time gate limit value of cell signal strength/quality requirement.It should be understood that cell signal strength/quality gate by the requirement
Limit value and desired time gate limit value improve, and exactly improve gravity treatment and initiate access module to any access module on first direction
The difficulty of gravity treatment, so as to reach the purpose for preventing that ping-pong reselection from occurring.Specifically, cell signal strength/quality of the requirement
The raising stepping of threshold value and desired time gate limit value can be set, for example be arranged to 9dB and 5s.
In other embodiments, reselection conditions can also be only comprising in the communication terminal gravity treatment to the first direction
Cell signal strength/quality threshold or the communication terminal required by any access module are resident the gravity treatment initiation and connect
Cell signal strength/quality required time thresholding of any access module on the first direction is measured when entering pattern
Value, it can equally increase communication terminal and initiate difficulty of the access module to any access module gravity treatment on first direction from gravity treatment
Degree, so as to limit the generation of ping-pong reselection.
It should be noted that after each ping-pong reselection of communication terminal, the reselection conditions can be all improved.And from a certain heavy
Ping-pong reselection is possible to repeat to occur between having published the pattern that access module sets out, therefore reselection conditions can be with gravity treatment frequency
Step up, that is to say, that between the easier access module that ping-pong reselection occurs, gravity treatment thresholding will be stricter.So also comply with
The demand of actual use, avoid the frequent generation of ping-pong reselection.
To sum up, compared with prior art, the method that ping-pong reselection prevents between the pattern for the communication terminal that the present embodiment provides,
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, when mode sequences are ranked up according to each self-corresponding pre-set priority of access module, only improve
The access module of higher priority can overcome prior art to cause to the reselection conditions for the access module for handing over low priority
Communication terminal the shortcomings that residing in the network of non-optimal access module for a long time, can guarantee that user obtains optimal service,
Improve the performance of communication terminal and the Experience Degree of user.
Embodiment three
The present embodiment provides ping-pong reselection prevention method between the pattern of another communication terminal, as shown in figure 4, bag
Include：
Step S41：Each access module in addition to last a kind of access module on the first direction is set respectively pair
The second timer answered.Wherein the second timer is used for recovering any access mould on gravity treatment initiation access module to first direction
Formula carries out the reselection conditions of cell reselection.It is exactly MODE1 and MODE2 to be set respectively respectively correspondingly still by taking three mould mobile phones as an example
The second timer TR1 and TR2.
Step S42：After ping-pong reselection between identifying the pattern initiating access module by the gravity treatment, communication is improved
The gravity treatment that terminal meets required by initiating access module to any access module progress cell reselection on first direction from gravity treatment
Condition, and start the gravity treatment and initiate the second timer corresponding to access module.I.e. when communication terminal confirms that there occurs from MODE1
Between the pattern set out after ping-pong reselection, while the reselection conditions are improved, also to start TR1.Wherein, sent out by the gravity treatment
The identification process for playing ping-pong reselection between the pattern set out of access module may be referred to embodiment one, improve the mistake of the reselection conditions
Journey may be referred to the embodiment of the present invention two, will not be repeated here.
Step S43：If the run time that the second timer corresponding to access module is initiated in the gravity treatment is default more than second
Time, then reduce the communication terminal and entered from gravity treatment initiation access module to any access module on the first direction
The required reselection conditions met of row cell reselection.Wherein, the second preset time by communication terminal corresponding access module with
The time-consuming of cell reselection is carried out between other access modules and determines that general span is plus certain Idle state stand-by time
30~180 seconds, specific value can determine according to the aggregation of data of Practical on-site test, such as when MODE2 is WCDMA,
Second preset time can be set as 70 seconds.The reselection conditions include the communication terminal gravity treatment to the first direction
Cell signal strength/quality threshold and the communication terminal required by any access module are resident the gravity treatment initiation access
Cell signal strength/quality required time threshold value of any access module on the first direction is measured during pattern.
In other embodiments, the reselection conditions can only include any one in above-mentioned two condition, and should be with being carried in step S42
Setting during the high reselection conditions is corresponding.Specifically, the increase of expired times can be run progressively according to the second timer
Reduce the reselection conditions, until reselection conditions recover to from gravity treatment initiate access module pattern between ping-pong reselection without
The initial condition of pass；Disposably reselection conditions can also be reduced to and initiate to rattle between the pattern of access module from gravity treatment
The unrelated initial condition of gravity treatment.Wherein, the expired times refer to the second timer run time more than the second preset time
Number, and when the reselection conditions at each overtime moment do not recover to also and initiate to rattle between the pattern of access module from gravity treatment
During the unrelated initial condition of gravity treatment, then the second timer is restarted.When selection gradually reduces, reduce stepping and could be arranged to
As improving stepping, raising stepping is might be less that, than the cell signal strength/quality threshold required as will be described and is wanted
The reduction stepping for the time gate limit value asked is respectively set to 3dB and 3s.
In addition, from gravity treatment initiate access module pattern between ping-pong reselection may repeat occur, when gravity treatment again
Secondary is during the second timer operation corresponding to access module is initiated in gravity treatment, then needs to restart corresponding second meter
When device, that is, restart timing after recovering the second timer reset condition, i.e., first reset the second timer and restart second again
Timer.
To sum up, the method that ping-pong reselection prevents between the pattern for the communication terminal that the present embodiment provides, due to setting for timer
The quantity put and the probability for starting timer operation have a considerable amount of reductions, can be that communication terminal saves system resource, carry
