Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of method and directional migration equipment of directional migration.
Background technology
1999 by 3GPP (The 3rd Generation Partnership Project, third generation partner program) MSC Pool (Mobile Switching Center Pool is proposed, MSC pool) technology, compare with the mode of traditional networking, this MSC Pool technology has been introduced the concept of " Chi Qu " (Pool Area): form a MSC area pond by a plurality of mobile switching centres (comprising MSC (Mobile Switching Center) or MSS (Mobile Switching Center Server)), a BSC/RNC (Base Station Controller/Radio Network Controller, base station controller/radio network controller) can be connected to a plurality of mobile switching centres in the pool area simultaneously.Behind BSC/RNC of terminal (MS or UE) access, BSC/RNC can be with this endpoint registration to any one mobile switching centre that this BSC/RNC connects.

1During access MSC area pond, NNSF (Network attached storage Node Selection Function, Non-Access Stratum node) can be according to this BSC
1The parameter of accessible MSC (such as MSC capacity factor measure, A mouth telephone traffic etc.) goes to inquire about the load of current each MSC according to the algorithm of setting, and then according to the principle of MSC load balancing is that terminal is specified a suitable MSC.
The MSC of appointment will be to TMSI of terminal distribution (Temporary Mobile Subscriber Identity, interim identification code), NRI (the Nomura Research Institute that comprises the MSC of this appointment among the described TMSI, Internet resources represent) value, so that migrate when terminal, access other BSC in the same MSC area pond
2During the region within the jurisdiction, BSC
2Corresponding MGW
2The NRI value inquiry relevant configuration of carrying among the TMSI of (Media Gate Way, media gateway) meeting according to terminal is determined MSC specified when terminal accesses first, and terminal is accessed to the MSC of appointment.This shows that a terminal operating provides service with the same MSC that continues by appointment in a MSC Pool scope time.
Since the NNSF in the MSC Pool technology to the terminal of first access when distributing MSC, follow the principle of MSC equally loaded, terminal being assigned on the different MS C by equilibrium under the same BSC just may appear, because the terminal geographic position under the same BSC approaches, (for example: office may be positioned at same place, the place that concentrate the residential quarter etc.), therefore, when the terminal distribution under the same BSC is arrived different MSC, calling between the terminal under the same BSC is the station to station call between different MS C, a large amount of station to station calls will take a large amount of Internet resources and route data, increase the expense of Internet resources, may also can bring the problems such as the increase of call connection time delay and the increase of connection error rate, so that user perceptibility is poor.

Described station to station call refers to the calling that the calling and called terminal produces when accessing different mobile switching centres.
Below in conjunction with Figure of description the embodiment of the invention is described in detail.
Embodiment one:
As shown in Figure 1, be the method flow diagram of a kind of directional migration in the present embodiment one.The implementation of present embodiment one comprises following step:
Step 101: obtain the call information of calling and called terminal room, determine respectively the positional information of calling and called terminal and the mobile switching centre's information that accesses according to call information.
Step 102: according to the positional information of calling and called terminal, judge whether the calling and called terminal is arranged in same setting regions, if then execution in step 103, otherwise described calling and called terminal is not carried out the migration of mobile switching centre.
In the scheme of present embodiment, the situation that the calling and called terminal can be positioned at same position district code LAC is regarded the situation that is positioned at same setting regions as, or whether be arranged in same setting regions according to the Distance Judgment calling and called terminal between the calling and called terminal, such as the distance between the calling and called terminal less than a certain threshold value, can regard the situation that is positioned at same setting regions as, otherwise, for being positioned at the situation of zones of different.
Step 103: according to the mobile switching centre's information that accesses, whether what judge calling and called terminal access is different mobile switching centres in the same area pond, if then execution in step 104, otherwise described calling and called terminal is not carried out the migration of mobile switching centre.
For different pool areas, can produce the list of identification information of different mobile switching centres, mobile switching centre's identification information that the mobile switching centre's acquisition of information calling and called terminal that accesses according to the calling and called terminal of determining accesses, can compare with mobile switching centre's list of identification information of storage, and then judge whether the mobile switching centre that the calling and called terminal accesses belongs to the same area pond, and then judge whether it is different mobile switching centres in the same area pond.
Need to prove that step 102 and step 103 are not limited to the described order of present embodiment at execution sequence, also can first execution in step 103 again execution in step 102, perhaps two step executed in parallel.
Step 104: a mobile switching centre in the mobile switching centre that indication calling and called terminal accesses respectively migrates to another mobile switching centre with calling terminal or the terminal called of access.
The specific implementation of this step is: the mobile switching centre of indication status of calling terminal access migrates to the mobile switching centre that terminal called accesses with calling terminal, make the calling and called terminal access same mobile switching centre, original station to station call is converted to office call; Perhaps, the mobile switching centre of indication terminal called access migrates to the mobile switching centre that calling terminal accesses with terminal called, makes the calling and called terminal access same mobile switching centre, and original station to station call is converted to office call.
Scheme by above-described embodiment one, what determine that calling and called terminal in the same setting regions adopts is the station to station call mode, and then by the migration pattern between the mobile switching centre, the method of calling of the calling and called terminal in the same setting regions is become office call, so just reduced the quantity of station to station call in the same area pond, save the expense of Internet resources, also reduced the time of Call Waiting simultaneously, improved user perceptibility.
Embodiment two:
As shown in Figure 2, be the method flow diagram of a kind of directional migration in the present embodiment two.Present embodiment two is that the scheme of present embodiment two may further comprise the steps to the detailed description of the specific implementation of each step among the embodiment one:
Step 201: obtain the call information between each terminal, for the terminal that produces described call information is respectively distributed a migration sign.
Need to prove, in the structure of MSC Pool networking, can read the call information of each terminal room from other call record real-time statistics system (such as signaling monitoring system, ticket collection system etc.) database, also can be local the collection and the call information of each terminal room of storage.
More preferably, the call information that obtains can be the access different mobile switching centres terminal between station to station call information.
Comprise in the described call information: (for example: the LAC of calling and called lane place (Location Area Code call out the number, calling and called positional information of time, the calling and called terminal in each stage, Location Area Code), residential quarter CI (Community Identity, cell ID) or SAC (Service Area Code, the coverage sign)), the information such as roaming number and calling and called switch ID.
Gathering also in this locality, the mode of stored calls information can be following two kinds:
The first is not distinguish the mode of mobile switching centre, the call information that all terminals produce is all recorded, and then from a large amount of call information that records, found out the call information that produces between a certain calling and called terminal.
The second is that mobile switching centre is divided into groups in twos, and the call information that the terminal room of two mobile switching centres in same group of the access produces is stored.For example: three moving exchanging center MSCs 1, MSC2, MSC3 are pairwise grouping, obtain MSC1/MSC2 group, MSC1/MSC3 group, MSC2/MSC3 group, to access then that the call information that produces carries out record between the terminal of the terminal of MSC1 and access MSC2, it is identical to organize the operation of organizing with MSC2/MSC3 for MSC1/MSC3, and then obtains the call information of each terminal room.
According to gathering the also mode difference of stored calls information, also different to the method for terminal distribution migration sign.
Do not come stored calls information if do not distinguish the mode of mobile switching centre with above-mentioned the first, then can be followed successively by migration sign of each terminal distribution, at this moment, the migration sign that different terminals distributes can be identical, also can be different.
If come stored calls information with above-mentioned the second packet mode, then will distribute successively a migration sign for terminal corresponding to the call information of each group, the migration sign that the terminal in same group is distributed can be identical, also can be different; The migration sign of not distributing between on the same group also can be identical or not identical.
Need to prove that the migration sign can be the 2 system numbers of a 8bit, also can be other forms of number.For example, the migration sign is chosen as the 2 system numbers of a 8bit, and so migration sign is initialized as 00000000.
Step 202: from the described call information that obtains, inquire the call information between a certain calling and called terminal, and then therefrom determine the positional information of calling and called terminal and the mobile switching centre's information that accesses.
In the scheme of this step, can be according to number and the call time of calling and called terminal, determine corresponding call information, and then when determining that from the call information of determining this is called out, the positional information of calling and called terminal and the mobile switching centre's information that accesses.
Step 203: according to the positional information of calling and called terminal, judge whether the calling and called terminal is positioned under the same LAC, if then execution in step 204, otherwise, determine that the calling and called terminal is not positioned at same setting regions, need not to move.
Need to prove, because the number of calls that nearer terminal room is called out on the physical location accounts for the highest proportion in call model, therefore, the positional information of two pairs of calling and called terminals of present embodiment is judged, to be converted to office call to the station to station call of the approaching terminal in position for follow-up, effectively to reduce the quantity of station to station call, saved the expense of Internet resources.
Described setting regions can be the zone that certain base station covers, and also can be that regulation belongs to the same area after the Region Segmentation of carrying out according to the criteria for classifying, can also be the LAC scope.
Step 204: according to the mobile switching centre's information that accesses, whether what judge calling and called terminal access is different mobile switching centres in the same area pond, if then execution in step 205, otherwise, need not to move.
The calling that produces between the terminal for different mobile switching centres in access the same area pond all is station to station call, therefore, can carry out follow-up migration operation for this Terminal Type, to reduce station to station call; For the terminal of the identical mobile switching centre in access the same area pond, the calling that produces is office call, therefore, does not need to move; Terminal for the mobile switching centre in the access zones of different pond no matter whether produce station to station call, owing to can't move between the zones of different pond, therefore, does not need to carry out follow-up migration operation yet.
Step 205: determine that described calling and called terminal is terminal to be migrated, and the sign of the mobile switching centre of the sign of terminal to be migrated and the current access of terminal to be migrated is stored in the tabulation to be migrated.
Step 206: in the statistics setting-up time length, the talk times of described calling and called terminal room.
Step 207: the calling and called terminal in the migration tabulation is judged according to predefined startup transition condition, if meet the startup transition condition of setting, then the sign with calling and called terminal in the tabulation to be migrated is placed in the preparation migration series, and be according to common call number of the common distribution of calling and called terminal, otherwise, suspend migration, again migration after meeting the startup transition condition.
Described startup transition condition is described master, the talk times of terminal called in setting-up time length reaches set point, perhaps, determine described master, the mobile switching centre that terminal called accesses, and the definite talk times of other-end in setting-up time length that accesses these two mobile switching centres, only have talk times just to meet the startup transition condition according to from high to low order rank in the terminal of top N, that is to say, described master, the talk times of terminal called in setting-up time length compared with the talk times that other access the terminal room of identical mobile switching centre, rank when top N, described master, terminal called just meets the startup transition condition of setting.
For example: current calling terminal access MSC1, terminal called access MSC2, at this moment, also have terminal A and the terminal B of mutually intercommunication also to access respectively MSC1 and MSC2, terminal C and the terminal D of intercommunication also access respectively MSC1 and MSC2 mutually, if main, talk times between the terminal called in setting-up time length is 5 times, talk times between terminal A and the terminal B in setting-up time length is 4 times, talk times between terminal C and the terminal D in setting-up time length is 8 times, then according to after the talk times ordering, the talk times of terminal C and terminal D makes number one, main, the talk times of terminal called comes second, the talk times of terminal A and terminal B comes the 3rd, and is if top N refers to front 2, then main, terminal called meets the startup transition condition of setting; If if top N refers to front 1, then the calling and called terminal does not meet the startup transition condition of setting.
Call number described in the present embodiment can be the natural number since 1.
Step 208: carry out the judgement of migration rules to entering the calling and called terminal of preparing migration series, and issue the migration instruction according to the result who judges.The concrete mode of the judgement of migration rules is as follows:
The first step: when the migration of calling and called terminal sign is identical in preparing migration series, then move according to the parity of the sequence number of calling and called terminal distribution.
Particularly, if the common call number of distributing of calling and called terminal is odd number, the mobile switching centre that then indicates terminal called to access migrates to the mobile switching centre that calling terminal accesses with described terminal called, if the common call number of distributing of calling and called terminal is even number, then the mobile switching centre that accesses of indication status of calling terminal migrates to the mobile switching centre that terminal called accesses with described calling terminal; Perhaps, if the common call number of distributing of calling and called terminal is odd number, then the mobile switching centre that accesses of indication status of calling terminal migrates to the mobile switching centre that terminal called accesses with described calling terminal, if the common call number of distributing of calling and called terminal is even number, the mobile switching centre that then indicates terminal called to access migrates to the mobile switching centre that calling terminal accesses with described terminal called.
Second step: when the migration of calling and called terminal sign is not identical in preparing migration series, then move according to the size differences relation of calling and called terminal transfer sign.
A kind of decision procedure is: when the absolute value of the difference of migration sign greater than the deviation thresholding, then the mobile switching centre that accesses of indication status of calling terminal migrates to the mobile switching centre that terminal called accesses with calling terminal, when the absolute value of the difference of migration sign is not more than the deviation thresholding, the mobile switching centre that then indicates terminal called to access migrates to the mobile switching centre that calling terminal accesses with terminal called;
Perhaps, when the absolute value of the difference of migration sign greater than the deviation thresholding, the mobile switching centre that then indicates terminal called to access migrates to the mobile switching centre that calling terminal accesses with terminal called, when the absolute value of the difference of migration sign is not more than the deviation thresholding, then the mobile switching centre that accesses of indication status of calling terminal migrates to the mobile switching centre that terminal called accesses with calling terminal.
Another kind of decision procedure is: when the migration sign of described calling and called terminal distribution is not identical, be assigned with in the indication calling and called terminal mobile switching centre that the less terminal of migration sign accesses with this terminal transfer to the mobile switching centre that is assigned with the larger terminal of migration sign and accesses.
Preferably, the present invention is except there being displacement equipment that terminal is moved the judgement, the judgement that can also be moved according to the load capacity of self by mobile switching centre.Particularly, each mobile switching centre in pool area (for example: when the VLR occupancy reaches certain higher limit or certain lower limit arranges the migration thresholding, stop migration or reduce migration quantity), the migration instruction of namely initiating in above-mentioned situation for directional migration equipment does not respond, and can avoid like this load imbalance of the mobile switching centre under the abnormal conditions.
In addition, can also control the time of migration, carry out directional migration when the load that is arranged on network state is the most stable less than the quantity of a certain set point (network idle) or mobile switching centre's terminal, also can arrange and carry out directional migration in the fixing duration.
Step 209: according to the corresponding relation between the sign of the mobile switching centre of the sign of calling and called terminal and current access, the mobile switching centre of calling and called terminal access issues the migration instruction in the pool area, the mobile switching centre that receives the migration instruction according to the migration instruction with the migration terminal transfer of appointment to the mobile switching centre of appointment.
Particularly, suppose that the MSC1 of this step indication status of calling terminal access migrates to calling terminal the MSC2 of terminal called access, then MSC1 is after receiving the migration instruction, determine that calling terminal need to migrate to MSC2, and the every terms of information of calling terminal in MSC1 sent to MSC2, the calling terminal that requires the MSC2 access to migrate to is finished calling terminal from the migration of MSC1 to MSC2.
After the terminal transfer success, can upgrade and save as the migration sign of calling and called terminal distribution, and the arbitrary terminal in described calling and called terminal is when needing again directional migration, migration sign after the renewal is carried out directional migration, so that this calling and called terminal when communicating by letter with other-end, can use migration sign after the renewal again to carry out the scheme of present embodiment again.Particularly, if described migration sign is the 2 system numbers of 8bit, its initial value is 00000000, and then described renewal migration sign can refer to position, migration sign end is added 1.For example, the migration before upgrading is designated 11110000, then carry out the migration operation of a present embodiment after, this migration identification renewal is 11110001; If the migration before upgrading is designated 11111111, then carry out the migration operation of a present embodiment after, this migration identification renewal is 00000000.
Need to prove, when terminal is conversed from different terminals in the same area pond always, so employed migration sign all is migration sign after upgrading during described terminal transfer, leave pool area when described terminal and will discharge the migration sign, will again be assigned with the migration sign when accessing again this pool area.
Scheme by present embodiment, just so that the station to station call under the same LAC has become office call, and then reduced station to station call quantity in the same area pond, and by quantitatively, the rule such as timing, effective restriction has also been carried out in migration, the loading condition of the mobile switching centre after also guaranteeing to move, simultaneously, station to station call is become office call, effectively improved the utilance of Internet resources.
