Description

A kind of update method of Acceditation Area and equipment

Technical field

The present invention relates to networking technology area, relate in particular to a kind of update method and equipment of Acceditation Area.

Background technology

In the existing 2G/3G network, UE (User Equipment, user terminal) select or gravity treatment behind the Cell (sub-district), be registered to core net, SGSN in the network (Serving GPRS SupportNode, Serving GPRS Support Node) or MSC (Mobile Switch Centre, mobile switching centre) can distribute to Acceditation Area of UE, be LA (LocationArea, the band of position) or RA (RoutingArea, Routing Area).Wherein, MSC distributes LA to UE, corresponding to CS territory business; SGSN distributes RA to UE, and corresponding to PS territory business, and RA equates with LA or the subclass of LA.If UE is moved, all to initiate LAU (Location AreaUpdate, the band of position is upgraded) or RAU (Routing Area Update, routing region updating) process immediately at LA of every replacing or RA.Certainly UE also has periodic position updating process under the situation of not changing LA/RA, and its effect is to make network understand UE at present also at network, prevent the UE deviated from network and network is not understood and constantly the situation of paging UE take place.

In the high population density zone, the personnel movement of group can make a large number of users almost move to new Acceditation Area simultaneously, be so-called RED (Registration in Densely-populated area, high population density regional registration), bring a large amount of paroxysmal business.A large amount of registration business not only can consumption systems resource, may cause the paroxysmal signaling traffic load of system too high, cause traffic congestion easily, other Client-initiated proper communication business at Acceditation Area edge are affected, cause the decline of QoS of customer and satisfaction.Therefore, how to satisfy the RED demand and promptly solve the sudden high system loading that the high population density regional registration causes, just become a problem that becomes more and more important.

In the prior art, in the SAE network in order to prevent that UE from frequently initiating TAU (Tracking Area Updating, tracking area update) process when changing TA (Tracking Area, tracing area), MME distributes a TAList (Tracking Area List, tracking area tabulation) to UE.Therefore, the SAE network has come down to introduce the notion of Multiple Registration Area (many Acceditation Areas), just network allows to distribute to many TA of UE (also can be interpreted as distributing to the TA List that one of UE comprises a plurality of TA), makes UE to be registered in simultaneously in a plurality of TA.This is different with the UMTS network, and under the UMTS network, network can only be distributed to LA of UE or RA, and UE can only be registered in the LA/RA at every turn.Comprise one group of TA in TA List, UE when mobile, do not need to initiate the TAU process, thereby has saved Internet resources in this group TA like this.Certainly the periodic location update process is still carried out in this case.And for TA list, network side can distribute identical TA list according to pre-configured all UE that give, and also may be that UE distributes different TA list according to the mobility of each UE.

The TAU flow process of striding MME in the existing SAE network as shown in Figure 1, the relevant following steps that mainly contain:

Step s101.UE detects and has entered new TA, and this TA is in its existing TA List, and this TA List gives UE by network allocation when UE is registered to network.

Step s102.UE sends TAU Request message to eNodeB, thereby initiates the TAU process by RRC (Radio Resource Control, Radio Resource control) message.This TAU Request message is in the NAS of RRC message cell, and eNodeB only receives RRC message, and does not resolve NAS message.Comprise old S-TMSI in the TAU Request message, old TAI, parameters such as Selected Network.

Old S-TMSI and the Selected Network of step s103.eNodeB from the TAU Request message of receiving selects corresponding MME, and be established to the connection of this MME, and this TAURequest message is received that with eNodeB overall unique E-UTRAN Area ID (being E-UTRAN ID) of the sub-district of this message is transmitted to MME.

If there is not corresponding MME, then eNodeB selects a new MME based on " MME selection function ", and this TAU Request message is received that with eNodeB overall unique E-UTRAN Area ID of the sub-district of this message is transmitted to MME.

In this routine process, by step s104～s118, eNodeB selects a new MME.

After step s119. normally executes other process (arrive HSS as upgrading the position, limit, insert restriction and signatory inspection etc. by regional subscription), new core net node (as MME) returns TAUAccept (TA List etc.) message to UE, if new core net node (as MME) distributes new S-TMSI to give UE, then this S-TMSI is also contained in this TAU Accept message.

If step s120. S-TMSI changes, UE will return TAU Complete message and give new core net node (as MME), to acknowledge receipt of new S-TMSI.

In the SAE network, a plurality of MME also can form a Pool, and each Pool comes unique identification with Pool ID or MMEGI (MME Group ID), and this Pool (or Group, MME down together) comes unique identification with MMEC (MME Code), and the UE in each MME identifies with M-TMSI.MMEGI has formed MMEI (MME ID) with MMEC, be used for unique MME of sign in a Group, and MMEI and MCC (Mobile Country Code, mobile subscriber's country code), MNC (Mobile Network Code, mobile subscriber's affiliated PLMN net code) formed GUMMEI (Globally Unique MME Identifier together, globally unique MMEID, the i.e. sign of core net node MME), be used at MME of globally unique sign.Correspondingly, a globally unique UE temporary mark is arranged also, i.e. GUTI (Globally Unique TemporaryIdentifier, whole world unique temporary identity, be the user identity temporary mark, its effect is similar to the P-TMSI in the 2G/3G network), GUTI is made up of GUMMEI and M-TMSI.When paging UE, in order to save the aerial signaling resource, system comes paging UE with the S-TMSI that simplifies, and wherein S-TMSI is made up of MMEC and M-TMSI, and S-TMSI has identified the particular UE under the specific MME among the MME Group.

At a Pool (or Group, down together), there are all interior RAN nodes (as eNodeB) of a plurality of CN nodes (as MME) and Pool to link to each other, when a UE initially enters Pool, the RAN node can be according to CN node of selections such as load balancing principle, UE moves in this Pool or inserts like this, is anchored on selected CN node all the time.Therefore, the MME that links to each other with all RAN nodes (as eNodeB) in the Pool just forms a MME Pool, and in the SAE network, also allows the Overlapping (overlapping) of Pool.In addition, SAE network regulation, MME Pool comprises complete TA, and just all TA among MME Pool can provide service by all MME among this Pool.Like this, UE does not need to change CN node (not needing to change MME) when mobile in whole Pool, and UE only when changing Pool, just can change the CN node.

In SAE, in conjunction with the notion of Pool and TA List, when MME belonged to some Pool, this MME distributed to each TA among the TA List of UE, can only form by some TA that belong to the MME service in the same Pool, and can not comprise other TA outside this Pool service range.That is to say the service range that the TAList that MME distributes can not cross over Pool.

About the notion of Pool among the SAE and TA, can be the example explanation by Fig. 2.

Among Fig. 2, suppose that some different MME form MME Pool 1 and MME Pool 2 (being called for short Pool 1 and Pool 2 respectively) respectively, eNodeB1, eNodeB2 and eNodeB3 link to each other with MME among the Pool 1, eNodeB2, eNodeB3 and eNodeB4 link to each other with MME among the Pool2, TA by MME service among the Pool 1 comprises TA1 and TA2, TA by MME service among the Pool 2 comprises TA2 and TA3, and eNodeB1 is positioned at the scope of TA1, eNodeB2 and eNodeB3 belong in the scope of TA2, and eNodeB4 is positioned at the scope of TA3.

Consider that earlier MME distributes the situation of a TA at every turn to UE.When UE enters MME Pool1 for the first time, enter eNodeB 1 and TA1 as UE, then UE selects a MME from MME Pool 1.UE from eNodeB1 to eNodeB2 in the moving process of eNodeB3, although TAU may take place in UE when moving to different TA (TA1-〉TA2), but because eNodeB1, eNodeB2 and eNodeB3 link to each other with MME among the Pool 1, so UE does not need to change simultaneously core net node MME (being the TAU without MME change or pool change among Fig. 2).Up to entering eNodeB4, because this eNodeB and source MME do not have interface (this eNodeB4 only belongs to Pool 2), then need to reselect the MME (being the TAU with MME change and poolchange among Fig. 2) among the Pool 2, the change (being also referred to as MME Relocation, the MME migration) of core net node promptly takes place.

Consider that again MME gives the situation of UE distribution T A List at every turn.If UE is in Pool 1 registration among Fig. 2, the MME among the Pool1 can distribution T A list be TA1 and TA2, and then UE moves around between eNodeB1 and eNodeB2 does not need to initiate to upgrade yet, and promptly UE does not need to initiate to upgrade when mobile in the TA list that distributes.But the MME among the Pool 1 can not distribute to UE with TA3.So UE can initiate to upgrade when TA2 moves to TA3, and the migration (being the TAU with MME change and pool change among Fig. 2) of core net node takes place.

In addition, eNodeB2 and eNodeB3 belong to two MME Pool simultaneously among Fig. 2, promptly with two Pool in all MME interface is all arranged, so eNodeB2 and eNodeB3 are exactly the Overlapping part of Pool 1 and Pool2, TA2 also can simultaneously provide service by the MME among two Pool.The benefit of Overlapping is, when UE returns eNodeB3 again from eNodeB4, because eNodeB3 has with Pool2 and is connected, therefore do not need to reselect MME, just can select MME once more up to entering eNodeB1, MME Relocation (migration) takes place, and promptly Overlapping has avoided table tennis Relocation.If eNodeB3 and Pool 2 do not have interface, UE moves around between eNodeB3 and eNodeB4 so, then will initiate the MME Relocation that rattles.

On the basis of the TA of SAE notion, adopt the method for TAList can alleviate aforesaid RED problem to a certain extent.The scene of a large amount of personnel movement that cause with subway operation etc. is an example, as shown in Figure 3.

Cover by TA1 to TA6 along the line as subway,, then can avoid a large amount of UE after entering a new TA, to initiate TAU simultaneously if different UE distributes different TA list.For example, when entering TA1, the TA List that distributes for different UE is as follows:

The TA list of UE1 be TA1, TA2, TA3},

The TA list of UE2 be TA1, TA2},

The TA list of UE3 be TA1},

The TA list of UE4 is { TA1, TA2, TA3, TA4}.

After these UE enter TA2 from TA1, have only some UE to initiate TAU so, promptly have only UE3 to initiate to upgrade in this example.Suppose that the new TA list that UE3 is assigned with is { TA2, TA3, TA4, TA5} in TA2, move on as all these UE so, when TA2 enters TA3, also have only part UE to initiate to upgrade again, as having only UE2 to initiate to upgrade in this example, distributing new TA list is { TA3, TA4}.In like manner, when these UE once more when TA3 enters TA4, also have only part UE to initiate to upgrade, as UE1, UE3, the TA list of Fen Peiing is { TA4, TA5} and { TA4, TA5, TA6} respectively.And the like, when these UE when TA4 enters TA5, have only UE4 to initiate to upgrade, distributing new TA list is { TA5, TA6}.UE enters TA6 from TA5, and UE1 distributes new TA list.So, network distributes different TA list by giving different UE, has avoided all UE to initiate the possibility of upgrading simultaneously to a certain extent, has also just reduced the sudden load of system.

The inventor finds to exist at least in the prior art following shortcoming in realizing process of the present invention:

According to prior art, all TA that can be assigned to same TA List belong to same MME Pool, that is to say that TA among these TA List is the border that can not cross over Pool.Continue above example explanation, suppose that TA1-7A6 belongs to Pool 1, TA7-TA9 belongs to Pool 2, and TA6 and TA7 lay respectively at the border of Pool 1 and Pool 2, that is to say that TA6 and TA7 can not be in same TA List, as shown in Figure 4.In case a large amount of UE continue from TA6 to going to TA7 to move, because TA7 does not belong to Pool 1, so all these UE still inevitably can initiate to upgrade when entering new TA7 simultaneously, cause congested.

Further, consider the situation of Pool Overlapping, as shown in Figure 5, suppose that TA7 is positioned at the overlapping region of Pool1 and Pool 2.Under the situation of this Pool Overlapping,, that is to say that TA7 can provide service simultaneously by the MME among Pool 1 and the Pool 2 though TA7 is positioned at Pool 1 and Pool 2 simultaneously.According to prior art, when TA7 provides service by any certain Pool (as Pool 1), the UE that in this Pool (as Pool 1) service range, moves, from other positions (as TA5) of this Pool when moving to TA7, needn't change core net node, that is to say, neither can be initiated to the migration of other MME among this Pool (as Pool 1), also can not be initiated to the migration of the MME among other Pool (as Pool 2).When TA7 distributes to UE by the MME among the Pool 1, during as TA among the TA List of UE, UE can initiate to upgrade when moving from TA6 to TA7.Along with UE continues to move to the TA8 direction, because TA8 belongs to Pool 2, even therefore the user has moved to TA7 this moment, the MME among the Pool 1 can not distribute to UE with the TA8 that is arranged in Pool 2, because the distribution of TA can not be crossed over Pool.So, according to prior art, when these UE continue when TA8 moves, still can be almost simultaneously occurrence positions upgrade, cause the high load capacity of system burst.

This shows, though TAList can stride MME, but still be subject to MME Pool, that is: when crossing over the border of Pool, still have a large amount of UE and almost initiate the position renewal simultaneously, thereby cause congestedly, therefore, this method can not fundamentally solve a large amount of mobile subscribers and initiate to register the high system loading problem that causes simultaneously.

Embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described further.

In the embodiments of the invention one, provide a kind of update method of Acceditation Area, as described below:

When existing several Pool overlapping, network is broadcasted certain notice explicit and/or implicit expression in the Acceditation Area (as TA) of overlapping region, this notice is used to refer to the position of the core net node (as MME) that some UE is initiated to other Pool and upgrades (as TAU), perhaps UE when being in connection status (as UE at access network process, in Attach or TAU, UE signaling connect or during data service carries out), network can upgrade in the position that certain or some TA initiate to change core net node by RRC and/or NAS message or other point-to-point message informing UE.UE is when entering certain Acceditation Area (as TA) of being positioned at the overlapping region or some Acceditation Area, some UE (as satisfying the UE of some specified conditions) can (as freely selecting or press certain rule or pressing system's indication etc.) initiate the TAU request, this TAU request can comprise certain parameter or indication/reason etc., indication access network node (as eNodeB) can be at this UE not according to NNSF (NAS Node Selection Function, the NAS node selection function) the original node of function selecting, select but can carry out the NAS node again, as being initiated to the registration of the core net node (as MME and/or SGSN) among another Pool, UE is registered to the core net node of new Pool and distributes new Acceditation Area or the Acceditation Area tabulation.

So, when a large amount of UE move to the overlay region, border of two Pool, some UE can be initiated to the Location Registration of the core net node of new Pool, and another part UE temporarily also is registered in the core net node of this Pool, that is to say that UE can disperse to be registered to the core net node of new Pool, thereby avoided all UE when crossing over Pool, to be initiated to the registration of new Pool simultaneously and the high system signaling load problem brought.

Perhaps UE can initiate TAU according to certain algorithm and be registered among the new Pool, as UE notified after, after postponing certain hour, initiate TAU according to algorithm and be linked into new Pool; Make all UE be linked into new Pool successively, replacement problem when can not stride Pool.

With Fig. 6 is example, some core net nodes (SGSN and/or MME) are formed two different Pool respectively, the Acceditation Area (as TA) of core net node (SGSN and/or MME) service comprises TA1, TA2, TA3, TA4 and TA4, TA5, TA6 respectively among two Pool, and wherein TA4 is positioned at the overlapping region of Pool 1 and Pool 2.Under the overlapping situation of this Pool, TA4 can provide service simultaneously by the MME among Pool 1 and the Pool2.

When the UE among the Pool 1 simultaneously or almost simultaneously moves to from TA1 the process of TA3, do not change core net node.When these UE continue to move to TA4, when just moving to the overlay region of Pool 1 and Pool 2, wherein some UE is initiated to the TAU of Pool 2, or part in addition all UE initiate TAU successively according to certain algorithm and (also may still choose on the NAS node among the Pool 1 with certain probability, if all choose on the Pool 2, also need to provide certain mechanism, the GUTI/GUMMEI that carries according to UE as access network node (as eNodeB) selects another Pool), promptly initiate to follow the TAU of core net node migration, be registered to Pool 2, the core net node that promptly changes by Pool 2 provides service.

Be that example illustrates with the TAU flow process of striding MME in the SAE network of Fig. 1 description below.For convenience, Fig. 7 has done certain simplification to Fig. 1 and has handled, and has kept the flow process that directly is closely related with the present invention, and flow process that will not have a direct relation briefly skips over.The key step that present embodiment relates to comprises:

Step s1001.UE detects and has entered new TA or Cell, and this TA or Cell are positioned at the Pool overlapping region.

The notice of network certain explicit or implicit expression of system broadcasts in this TA and/or Cell is (hereinafter to be referred as notice, but be not limited to notice, but comprise certain or some play indication and/or announcement/and/or any information of similar effect such as parameter and/or message and/or effect, particularly, this notice might but to be not limited to be certain and/or the indication of some priority, the algorithm indication, system message/parameter indication, numerical value indication or the like, with agreement, standard or specific implementation are relevant, as long as play similar effect and/or effect) or, UE obtained announcement information at access procedure before this, this announcement information includes but not limited to overlapping TA/Cell information such as (list), this notice be used for triggering or indication UE enter this/a little TA or Cell after, UE initiates to upgrade at once or according to certain algorithm, and this renewal can cause UE to be registered to the core net node (as MME) of other Pool.

As a kind of possible implementation wherein, as, network in the Overlapping zone or the specific region by system broadcast message broadcasting Pool ID or MMEGI, Pool ID herein both may be that the Pool ID of wherein some Pool is (as the Pool ID of the former registration of UE Pool, or the Pool ID of other Pool of Overlapping zone), also may be the Pool ID that broadcasts a plurality of (as two) or all Pool simultaneously.UE will handle according to the Pool ID that receives, as after description among the step s1002.

Further, network is at the notice of sending among this TA that each system broadcast message comprised, and its particular content might be identical, also might be different.If each broadcast announcement difference means that network is in batches or gradation or at the different UE of different time announcements.And this notice both might be by continuity broadcasting (being that each broadcasting all comprises this indication), also might be by discontinuity or periodic broadcast, even may be just to be broadcasted under given conditions.These are all relevant with agreement and/or standard and/or network operation strategy, collocation strategy and/or specific implementation.

The UE that step s1002. receives this notice takes corresponding processing.

Those UE that satisfy specified conditions send TAU Request message to access network node (as eNodeB) by RRC message, thereby initiate the TAU process.Herein " satisfying specified conditions " is meant the notice that satisfies among the step s1001.Particularly, as satisfy certain priority and require, satisfy certain algorithm exclusive disjunction result, satisfy certain numerical value, satisfy certain system parameters or indication etc.In a single day UE satisfies specified conditions, certain interval of time or send TAURequest message to access network node immediately or separately then with certain probability or in the mode of completely random, and concrete mode is with regulation or implement relevant.This TAU Request message will with one show or the indication of implicit expression (hereinafter to be referred as notice, but be not limited to notice, but comprise certain or some play indication and/or announcement/and/or any information of similar effect such as parameter and/or message and/or effect, as certain cause specific value) issue access network node (as eNodeB) together, this indication is used for triggering or indicates access network node (as eNodeB) not select the core net node of GUMMEI indication, but carry out new core net node selection course, perhaps directly select to be positioned at the core net node (as MME) of other Pool, promptly this TAU should be the TAU that changes core net node (as MME).

One concrete application of present embodiment one method that provides is as follows: network side is broadcasted Pool ID (or the MMEGI of current Pool in system broadcast message, down together), then UE can with the Pool ID that from broadcast, receives with own before the Pool ID of the Pool that registers compare, thereby whether what learn current access is original Pool.If find it is not original Pool, then UE can only carry MMEC and needn't carry complete GUMMEI in the RRC message that mails to access network node (as eNodeB), promptly do not carry other relevant informations (as MCC/MNC and/or MMEGroup ID etc.) of the core net node of former registration, access network node needn't read information (even can not carry GUMMEI etc. on RRC) such as MMEC, and access network node can directly be selected new core net node according to load balance or other principles.Can also reduce consumption like this to air interface resource and Internet resources.Certainly, if find it is original Pool, UE portability or do not carry relevant information and give access network node when inserting then, access network node only carries out the selection (and can carry MCC/MNC and/or MME GroupID etc.) of NAS node (being MME and/or SGSN) by MMEC (may also have MNC+MCC).So also can reduce consumption to air interface resource and Internet resources.

And in the overlapping region, network side can be broadcasted the PoolID of a plurality of or all Pool in system broadcast message, and like this, UE can be appreciated that the current Overlapping zone that is in a plurality of Pool.At this moment, UE can directly indicate access network node to initiate to change the TAU of core net node, in this case, partly or entirely UE is at once or with certain probability or initiate TAU within a certain period of time, in the RRC message that mails to access network node (as eNodeB), can only carry MMEC and needn't carry all GUMMTI, perhaps do not carry any GUMMEI information, or carry other indications, make access network node (directly or with certain probability) select new core net node according to principles such as load balances.

Perhaps, system can exist certain sequencing or logical order (as ID/ Pool ID of main Pool at the Pool ID of a plurality of Pool of overlapping region broadcasting, or a Pool ID/ the 2nd Pool ID etc., as long as can be used in the first-selected Pool ID that distinguishes this zone, reduce or avoid UE between a plurality of Pool, to come and go registration), the first-selected Pool ID in this zone that UE will receive and the Pool ID of own original registration compare, if the two is identical, then can not initiate or with certain probability (P1) or otherwise be initiated to the renewal of other Pool; If the two difference, then can all initiate or with certain probability (at least greater than P1) or otherwise initiate to upgrade, this renewal can all or with certain probability be linked into new Pool, can reduce or avoid UE between Pool, to initiate " table tennis registration " like this and (perhaps take other mode, as certain message of system broadcasts or indication, system gives some UE indication, judge according to the direction of motion of UE or speed and to carry out, the UE random wait, UE is according to algorithm execution etc., as long as can reduce or avoid UE between Pool, to initiate " table tennis registration "), reduce the system signaling expense.In this case, if UE need initiate to upgrade, then partly or entirely UE at once or with certain probability or initiate TAU within a certain period of time, and in the RRC message that mails to access network node (as eNodeB), can only carry MMEC and needn't carry all GUMMTI, perhaps do not carry any GUMMEI information, or carry other indications, make access network node (directly or with certain probability) select new core net node according to principles such as load balances.

Can reduce consumption like this to air interface resource and Internet resources.Be that UE needn't carry MME Group ID at least in access network process.

Those UE that do not satisfy above-mentioned specified conditions then can not initiate to change the TAU of core net node immediately.But not getting rid of these UE, this might not initiate other forms of TAU (not in its TA List as this TA, then this UE might initiate not change the TAU of core net node), and, as a kind of implementation method, these UE also might be behind one section different time at interval with certain probability or initiate to change the TAU of core net node in the mode of completely random, even these UE might satisfy the notice of system broadcasts next time, thereby initiate similar TAU.The processing mode of these UE and agreement and/or standard and/or network operation strategy, collocation strategy and/or specific implementation are relevant.

What further specify is, no matter whether this TA in the TA of UE List, can determine whether carrying out TAU according to ad hoc rules in fact.Said herein ad hoc rules both may be the regulation in agreement and/or the standard, also may be based on the method that equipment implementation and/or network operation strategy, network configuration etc. are determined.

Step s1003. access network node (as eNodeB) is selected corresponding core net node (as MME) according to the TAU Request message of receiving, and is established to the connection of this core net node (as MME).

If the indication that access network node (as eNodeB) is received the change core net node that step s1002 is listed, this indication is the core net node (as MME) that requirement access network node (eNodeB) triggering or indication access network node (as eNodeB) select to be positioned at other Pool, or carry out new core net node selection course, or trigger the core net node that other Pool were selected or selected to new node with certain probability, then this access network node (as eNodeB) should be selected other core net node (as MME), this means that this TAU should be the TAU that changes core net node (as MME).Under other situations, this access network node (as eNodeB) will be selected corresponding core net node (as MME) from old S-TMSI the TAU Request message of receiving and SelectedNetwork, and be established to the connection of this core net node (as MME).

Other steps of step s1004. as steps such as security inspection and position renewals, remain unchanged with existing procedure order and processing mode thereof.

Step s1005. is if normally execute other process, as the inspection etc. that limits or contract by regional subscription restriction, access, new core net node (as MME) returns TAU Accept (TA List etc.) message to UE, if new core net node (as MME) distributes new S-TMSI to give UE, then this S-TMSI is also contained in this TAU Accept message.

If step s1006. S-TMSI changes, UE will return TAU Complete message and give new core net node (as MME), to acknowledge receipt of new S-TMSI.

In the above-mentioned flow process, system broadcasts Pool-id under the region by broadcast, and this Pool-id can be MME Group ID, or MCC+MNC+Pool-id.When system configuration under the overlapping region, when being included in the unique MMEC of configuration under MOCN (the Multiple Operators Core Network MOCN) situation, if the MCC+MNC+Pool-id among the GUTI that UE find to distribute equals the MCC+MNC+Pool-id of network side broadcasting or in the MCC+MNC+Pool-idlist of network side broadcasting, then in access procedure, can only carry MMEC+M-TMSI.

If RAN is (Radio Access Network, wireless access network) read TMSI information in NAS (Non AccessStratum, the Non-Access Stratum) message, then UE can carry indication or cause value, if RAN can not read NAS message, then RAN directly selects new NAS node.

When system disposes MMEC and Pool-id among the Pool voluntarily, when MOCN also disposed voluntarily, UE according to circumstances carried each value among the GUTI.Specifically can be:

(1) when network was only broadcasted a MCC+MNC, then UE can not carry MCC+MNC

(1.1) when network was only broadcasted a MCC+MNC+Pool-id, then UE can not carry MCC+MNC+Pool-id.

(1.2) when a plurality of Pool-id of Web broadcast, need carry Pool-id, as also carrying among the service request flow process Service Request.

(2) when a plurality of MCC+MNC of Web broadcast, then carry MCC+MNC, also will carry as service request flow process Service Request.

(2.1) the different MCC+MNC when Web broadcast have identical Pool-id, can not carry Pool-id.

Mandatory declaration be, for the sake of simplicity, though above-mentioned example explanation is to represent Acceditation Area with TA, represent the position to upgrade with TAU, but the situation that never only comprises TA and TAU, but comprise the Acceditation Area of any area concept and/or form, as TA, RA, LA, XA (eXtended Area, extended area) etc.If consider and introduce new XAList and/or LA/RAList and other similar notions, this method also is suitable.And also just only comprising a registration area (as a TA) with Pool Overlapping in the above-mentioned explanation is example, in fact, in Pool Overlapping zone, also may include a plurality of Acceditation Areas (as a plurality of TA).In addition, this place has just pointed out two situations that Pool is overlapping, but this method never only limits to the situation of two Pool, that is to say, also may comprise the processing of a plurality of Pool.The situation of the expansion of all these explanations, the method for its concrete processing method and above-mentioned introduction substantially all are same or analogous.

Mandatory declaration is equally, though the situation that above-mentioned example is described when being the TAU of core net node (MME) migration in the SAE network, this method are equally applicable to the LAU/RAU situation of following core net node migration (SGSN) that takes place when the 2G/3G network is introduced Pool and LA/RA List.Further, this method also is applicable to the situation of the Location Registration of the system of spanning into, and has both comprised the interdepartmental system TAU of 2G/3G to the LTE/SAE network, also comprises the interdepartmental system RAU of LTE/SAE to the 2G/3G network.In addition, when introducing Pool and XA and XA List and/or other zone similarity notions between same connecting system and/or different access systems, this method also is suitable for.The extendible situation that all these are mentioned, the method for its concrete processing method and above-mentioned introduction substantially all are same or analogous.

In the embodiments of the invention two, provide a kind of update method of Acceditation Area, as described below:

When UE moved into place in the sub-district on adjacent Acceditation Area border (Cell), the carrier wave of this sub-district under monitoring this Acceditation Area, also monitoring was positioned at the carrier power of the sub-district of adjacent Acceditation Area, and carries out the sub-district gravity treatment under certain conditions.System is by certain rule or indicate some UE that satisfies condition to initiate the sub-district gravity treatment, and selects the sub-district under the adjacent Acceditation Area, thereby enters new Acceditation Area and carry out registration.Like this, the sub-district that different UE can be initiated to new sub-district respectively again, thereby disperse to be initiated to the LAU/RAU in new registration district, reduce the system burst signaling traffic load.

For example, whether decision resides in this sub-district to UE according to the signal strength signal intensity of adjacent sub-district, will the reading system broadcast after resident and then initiate the position and upgrade.Generally speaking, whether the resident sub-district of facing is to realize by certain algorithm in the UE decision, as:

for FDD cells： Srxlev>0 AND Squal>0 (1)

for TDD cells： Srxlev>0 (2)

Herein:

Squal＝Q _qualmeas-Qqualmin (3)

Srxlev＝Q _rxlevmeas-Qrxlevmin-Pcompensation (4)

Squal	Cell Selection quality value(dB) Applicable only for FDD cells.
		Srxlev	Cell Selection RX level value(dB)
Q qualmeas	Measured cell quality value.The quality of the received signal expressed in CPICH E c/N 0(dB)for FDD cells.CPICH Ec/N0 shall be averaged as specified in[10].Applicable only for FDD cells.
		Q rxlevmeas	Measured cell RX level value.This is received signal，CPICH RSCP for FDD cells(dBm) and P-CCPCH RSCP for TDD cells(dBm).
Qqualmin	Minimum required quality level in the cell(dB).Applicable only for FDD cells.
		Qrxlevmin	Minimum required RX level in the cell(dBm)
Pcompensation	max(UE_TXPWR_MAX_RACH-P_MAX，O)(dB)
		UE_TXPWR_MAX_RACH	Maximum TX power level an UE may use when accessing the cell on RACH(read in system information)(dBm)
P_MAX	Maximum RF output power of the UE(dBm)

Wherein, whether the Ec/No of above-mentioned formula (1) Primary Common Pilot Channel that is used to judge that terminal measures reaches requirement; Whether the code domain power of the received signal of the Primary Common Pilot Channel that formula (2) is used to judge that terminal measures reaches requirement.If all greater than zero, the signal quality that this sub-district is described so is an acceptable to the result of calculation of these two formula.Otherwise terminal can't be used this sub-district.

In the prior art, above-mentioned parameter is broadcasted in the current area system broadcast message.If system broadcast message changes these parameters/or algorithm, then may have part UE and carry out the sub-district according to certain algorithm and be stationed, part UE can not select new sub-district.Perhaps different UEs possesses different correction values or weighted value and participates in algorithm, and perhaps different UEs possesses different algorithms, makes same signal intensity for the effect difference of different UEs generation, causes the UE that has to select new sub-district, and the UE that has still is stationed former sub-district.Algorithm that these are different or parameter can be notified UE by point-to-point (as Attach Accept or TA Accept etc.) by network side, or notify UE (as UE itself classification being arranged, a kind of parameter of each class or algorithm) or be fixed on UE's by system broadcast message.

Be that example describes with the sub-district gravity treatment in the 2G/3G system below.

As shown in Figure 8, suppose that Cell 1, Cell 2, Cell 3 and Cell 4 are positioned at route district RA 1, and Cell 5, Cell 6 and Cell 7 are positioned at route district RA 2, wherein RA1 and RA2 are adjacent, and Cell 4 is adjacent with Cell 5.Because the intrinsic transmission characteristic of wireless signal, adjacent minizone are difficult to realize strict border, generally more or less all overlap each other.In this example, suppose Cell 4 and Cell 5 covering that overlaps each other.

Suppose that UE has been registered among the route district RA1, be in idle pulley (Idle Mode), and in RA 1 along Cell 1-Cell 2-Cell 3-Cell 4 moves, when moving to the overlay region of Cell 4 and Cell 5, the carrier wave of UE this sub-district (being Cell 2) under monitoring this Acceditation Area (being RA 1), also monitoring simultaneously is arranged in the carrier power of neighbor cell (as the Cell 5 of Fig. 8).

In the present embodiment, can make and with the following method whether UE be selected to switch to new sub-district and be provided with:

Step s1101. carries out static state or dynamic-configuration to network, make network in the appointed area of RA (as the RA2 among Fig. 8) (as edge cell, the Cell among Fig. 84 for example) certain notice of broadcasting in, this notice is used for triggering or indicates some UE that enters this Cell to be initiated to the sub-district gravity treatment of this Cell.

Further, this notice also may be separately or with other message or parameter, and explicit and/or implicit expression is listed or the Target cell (as Cell 5) when pointing out that UE carries out the sub-district gravity treatment.

Further, network is at the notice of sending among this RA that each broadcast comprised, and its particular content might be identical, also might be different.If each broadcast announcement difference means that network is in batches or gradation or at the different UE of different time announcements.And this notice both might be by continuity broadcasting (being that each broadcasting all comprises this indication), also might be by discontinuity or periodic broadcast, even may be just to be broadcasted under given conditions.These are all relevant with agreement and/or standard and/or network operation strategy, collocation strategy and/or specific implementation.

Step s1102. receives the action of the correspondence that the UE of this notice takes.

Those UE that satisfy specified conditions initiate cell reselection process, and Target cell is the sub-district under the adjacent route district.Herein " satisfying specified conditions " is meant the content that satisfies above-mentioned notice.Particularly, as satisfy certain priority and require, satisfy certain algorithm exclusive disjunction result, satisfy certain numerical value, satisfy certain system parameters etc.It should be noted that this moment, UE might satisfy the sub-district gravity treatment trigger condition of prior art regulation simultaneously, but also might not exclusively satisfy.In a single day UE satisfies aforesaid specified conditions, certain interval of time or initiate cell reselection process immediately or separately then with certain probability or in the mode of completely random, and choose the sub-district (as Cell 5) among the adjacent R A (as RA2).If this notice in step s1101 (also may with other message or parameter) is explicit or the Target cell (as Cell 5) of implicit expression when having specified UE to carry out the sub-district gravity treatment, then this UE gravity treatment is to this designated cell.

Those UE that do not satisfy above-mentioned specified conditions then needn't initiate to change the TAU of core net node immediately.But not getting rid of these UE, this might not initiate conventional sub-district gravity treatment (as the higher or better quality of the signal strength signal intensity that detects neighbor cell, thereby initiate the sub-district gravity treatment), and, as a kind of implementation method, these UE also might initiate the sub-district gravity treatment with certain probability or in the mode of completely random behind one section different time at interval, even these UE might satisfy the notice of system broadcasts next time, thereby initiate similar TAU.The processing mode of these UE and agreement and/or standard and/or network operation strategy, collocation strategy and/or specific implementation are relevant.

After step s1103. finished the sub-district gravity treatment, UE entered new RA, initiated normal RAU process again.

One concrete application scenarios of the described method of present embodiment is as follows:

As shown in Figure 9, two sub-district Cell 1 are adjacent with Cell 2, and existence overlaps each other, the subregion of A point overlapping region deflection Cell 1 among Fig. 9, B represents the zone of overlapping region deflection Cell 2, and middle, O point expression overlapping zone also is optimum sub-district gravity treatment point.For all UE that moving to Cell 2 from Cell1, in the overlapping region, must be accomplished to the sub-district gravity treatment of Cell 2.As a kind of implementation, can allow the high UE of priority finish the sub-district gravity treatment in the O zone, and priority low finish the sub-district gravity treatment at A or B zone.Like this, user's the sub-district gravity treatment time has scatter, and correspondingly, its registration business has also scatter, and has reduced the signaling traffic load of system.

In addition, the present invention can also expand to opposite situation, even be the sub-district gravity treatment trigger condition that some UE satisfies the prior art regulation, system also can indicate it not to be initiated to sub-district gravity treatment under the adjacent route district (secondary route district), or be initiated to sub-district gravity treatment under the adjacent route district after indicating it to postpone a period of time again, or the sub-district that is initiated to the different adjacent route district of another one (Third Road by district) again, or do not initiate sub-district gravity treatment etc., thereby make different UE disperse to carry out registration process, reduce the system burst signaling traffic load.

Mandatory declaration be, for the sake of simplicity, though above-mentioned example explanation is to represent Acceditation Area with RA, represent the position to upgrade with RAU, but never only comprise the situation of RA and RAU, but comprise the Acceditation Area of any area concept and/or form, as TA, RA, LA, XA etc.If consider and introduce new XAList and/or LA/RA List and other similar notions, this method also is suitable.And also just only comprising a sub-district with the overlay region of two Acceditation Areas (as RA) in the above-mentioned explanation is example, in fact, in the zone, overlay region, also may include a plurality of neighbor cells.In addition, this place has just pointed out the situation of two overlapping coverings of neighbor cell, but this method never only limits to the situation of two sub-districts, that is to say, also may comprise the processing of a plurality of sub-districts.The situation of the expansion of all these explanations, the method for its concrete processing method and above-mentioned introduction substantially all are same or analogous.

Same mandatory declaration is, though above-mentioned example describe be sub-district gravity treatment in the 2G/3G network time situation, thereby this method is equally applicable to take place when the 2G/3G network is introduced LA/RA List sub-district gravity treatment causes the situation of LAU/RAU.Further, this method also is applicable to the situation of the sub-district gravity treatment of the system of spanning into, and has both comprised the interdepartmental system sub-district gravity treatment of 2G/3G to the LTE/SAE network, also comprises the interdepartmental system sub-district gravity treatment of LTE/SAE to the 2G/3G network.In addition, when introducing Pool and XA and XA List and/or other zone similarity notions between same connecting system and/or different access systems, this method also is suitable for.The extendible situation that all these are mentioned, the method for its concrete processing method and above-mentioned introduction substantially all are same or analogous.

In the embodiments of the invention three, provide a kind of update method of Acceditation Area, as described below:

Static in advance or dynamically UE is carried out software and/or hardware configuration, make its trigger condition difference of carrying out the sub-district gravity treatment, as giving the power threshold of the different triggering cell gravity treatment of different UE configurations in advance.Like this, even a large amount of UE move to Acceditation Area (as the route district) border simultaneously, be in identical or similar wireless environment, but because the condition difference of triggering cell gravity treatment, these UE can not initiate the sub-district gravity treatment simultaneously yet, also avoid a large amount of UE to be initiated to the registration process in new registration district simultaneously thereupon, thereby reduced or avoided the sudden high signaling traffic load of system.

Need to prove that the above-mentioned foundation that in advance UE is configured may be, but to be not limited to be priority and/or other factors such as UE wireless capability and/or subscription data of user.

In addition, the described method of present embodiment also can combine use with embodiment two, to reach same or analogous technique effect.

Mandatory declaration be, for the sake of simplicity, though above-mentioned example explanation is to represent Acceditation Area with RA, represent the position to upgrade with RAU, but never only comprise the situation of RA and RAU, but comprise the Acceditation Area of any area concept and/or form, as TA, RA, LA, XA etc.If consider and introduce new XAList and/or LA/RA List and other similar notions, this method also is suitable.The situation of the expansion of all these explanations, the method for its concrete processing method and above-mentioned introduction substantially all are same or analogous.

In the embodiments of the invention four, provide a kind of update method of Acceditation Area, as described below:

Use the timesharing process registration, make different UE carry out registration process at different time.UE is after entering new LA/RA, system indicates some UE to initiate registration according to certain rule in particular moment by broadcast message, provide particular priority or algorithm indication as broadcast, can also be in conjunction with concrete time indication, the UE that only satisfies condition just initiates registration, and other UE wait broadcast announcement next time.Like this, the sub-district that different UE can be initiated to new sub-district respectively again, thereby disperse to be initiated to the LAU/RAU in new registration district, reduce the system burst signaling traffic load.

Be that example describes with the RAU process among the 2G/3G below.As shown in figure 10, suppose that Cell 1, Cell 2 are positioned at route district RA 1, and Cell 3, Cell 4 are positioned at route district RA 2, wherein RA1 and RA2 are adjacent, and Cell 2 is adjacent with Cell 3.

Further, the notice that each broadcast comprised that network sends at appointed area among this RA, its particular content might be identical, also might be different.If each broadcast announcement difference means that network is in batches or gradation or at the different UE of different time announcements.And this notice both might be by continuity broadcasting (being that each broadcasting all comprises this indication), also might be by discontinuity or periodic broadcast, even may be just to be broadcasted under given conditions.These are all relevant with agreement and/or standard and/or network operation strategy, collocation strategy and/or specific implementation.

Step s1302. receives the action of the correspondence that the UE of this notice takes.

Those UE that satisfy specified conditions are certain interval of time or initiate the RAU process with certain probability or in the mode of completely random immediately or separately, is registered to adjacent R A (as RA2)." satisfying specified conditions " herein is meant the meaning of the notice that satisfies step s1301, particularly, as satisfies certain priority and requires, satisfies certain algorithm exclusive disjunction result, satisfies certain numerical value, satisfies certain system parameters etc.

Those UE that do not satisfy above-mentioned specified conditions then can not initiate RAU immediately.But as a kind of implementation method, these UE also might initiate RAU with certain probability or in the mode of completely random behind one section different time at interval.Even these UE might satisfy the notice of system broadcasts next time, thereby initiate similar RAU.The processing mode of these UE and agreement and/or standard and/or network operation strategy, collocation strategy and/or specific implementation are relevant.

Mandatory declaration be, for the sake of simplicity, though above-mentioned example explanation is to represent Acceditation Area with RA, represent the position to upgrade with RAU, but never only comprise the situation of RA and RAU, but comprise the Acceditation Area of any area concept and/or form, as TA, RA, LA, XA etc.If consider and introduce new XAList and/or LA/RA List and other similar notions, this method also is suitable.And also just only comprising a sub-district with the overlay region of two Acceditation Areas (as RA) in the above-mentioned explanation is example, in fact, in the zone, overlay region, also may include a plurality of neighbor cells.In addition, this place has just pointed out the situation of two overlapping coverings of neighbor cell, but this method never only limits to the situation of two sub-districts, that is to say, also may comprise the processing of a plurality of sub-districts.The situation of the expansion of all these explanations, the method for its concrete processing method and above-mentioned introduction substantially all are same or analogous.
