Abstract

The invention which relates to the communication field discloses a mobile communication method, a mobile communication system and an access entity to increase the paging efficiency of UE, wherein when the access entity carries out UE location update or during access, whether the UE meets predetermined conditions is judged according to the current area in which the UE exists; if the UE meets the predetermined conditions, the paging of the UE is completed within the paging area to which the access entity belongs when needed, and is forbidden within the paging area to which the access entity belongs in other originally correlative networks. Moreover, the predetermined conditions are as follows: the space between the current area in which the UE exists and the paging area to which the access entity belongs in other originally correlative networks is more than a preset threshold, or both areas are not adjacent, or the access entity of the current area in which the UE exists is not correlative to the access entities in other originally correlative networks.

Description

Method of mobile communication, mobile communication system and access entity

Technical field

The present invention relates to the communications field, particularly the mobile technology of subscriber equipment in heterogeneous networks.

Background technology

3G is the abbreviation of English 3rd Generation, refers to the 3G (Third Generation) Moblie technology.The first generation is simulated standard type mobile communication technology (1G) and second generation global system for mobile communications (Global System formobile Communication relatively, abbreviation " GSM "), code division multiple access (Code Division MultipleAccess, be called for short " CDMA ") etc. digital mobile communication technology (2G), 3G is meant the third generation mobile communication system that multimedia communications such as radio communication and Internet are combined generally speaking.It can handle multiple media formats such as image, music, video flowing, and multiple information services such as comprising web page browsing, videoconference, ecommerce is provided.Yet, progressively development along with communication, people are more and more high for the requirement of mobile communication, existing third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") network architecture and agreement can't satisfy the high request of user for mobile communication, so 3GPP has proposed a kind of notion of serving the evolvement network of future communications demand.

In order to guarantee the competitiveness of 3GPP system in following 10 years down to the time more of a specified duration, particularly in order to strengthen the 3GPP system handles ability of the IP data service of growth fast, 3GPP has started Long Term Evolution (Long Term Evolution since the second half year in 2004, be called for short " LTE ") project, and System Architecture Evolution (System Architecture Evolution is called for short " SAE ") project.The purpose of LTE provides and a kind ofly can reduce time delay, improves user data rate, enhanced system capacity and coverage, and the evolvement network that reduces the whole cost of operator.Simultaneously, the network configuration of evolution also is an important index for the backwards compatibility of existing network.

Comprise in the principle that the network architecture of evolution need satisfy:

(1) at the initial phase of subscriber equipment access network, basic IP connects and need set up in the network of evolution;

(2) network architecture of evolution must minimize the time delay of user data;

(3) definition of each functional module should be avoided the overlapping or repetition of function in the evolution network framework, to avoid unnecessary signaling interaction and time delay.

A kind of comparatively popular network architecture of deriving out on above basis as shown in Figure 1, mainly comprise: mobile management entity (Mobility Management Entity, abbreviation " MME "), user entity (User Plane Entity, abbreviation " UPE "), wireless access network (the LTE Radio Access Network of user's face anchor point (User Plane Anchor) and evolvement network, abbreviation " LTE RAN ") four logic function modules, and home signature user server (Home Subscriber Server is called for short " HSS ") etc.MME wherein is the mobile management module, be responsible for the mobile management of chain of command, comprise the management of user's context and mobile status, distributing user temporary identity sign, mobility status, tracing area (Track Area, be called for short " TA ") information etc., and the user carried out authentication, it is corresponding to current universal mobile telecommunications system (Universal Mobile Telecommunications System, abbreviation " UMTS ") the control plane part of internal system GPRS serving GPRS support node (Serving GPRSSupport Node is called for short " SGSN "); UPE is a user entity, and the downlink data that is responsible for the subscriber equipment under the idle condition is initiated paging, and the interior routing iinformation of context, IP bearing parameter and network of subscriber equipment etc. is preserved in management, and it is corresponding to the datum plane part of the inner SGSN of current UMTS; User's face anchor point can comprise 3GPP anchor point (3GPP Anchor) and SAE anchor point (SAEAnchor), 3GPP Anchor is the user's face anchor point between different access systems in the 3GPP system, and SAEAnchor is the user's face anchor point between 3GPP connecting system and non-3 GPP system among the SAE.User's face anchor point is constant in user's Session Time.LTE RAN is the wireless access network of evolvement network, node is not wherein done concrete qualification, generally has eNodeB (evolution base station), can also comprise chain of command server (Control Plane Server, be called for short " CPS "), logically can be with it as Long Term Evolution radio access network entity (LTE-RAN Entity).

Because in actual applications, may exist simultaneously and adopt different radio access technologies (Radio AccessTechnology, abbreviation " RAT ") network configuration, UE moves (as network and the evolvement network of 2G/3G) between different RAT, UE can be because variation quarters at different networks rattles and cause network registration process.As shown in Figure 2, RA1 and RA2 are the route district (Routing Area is called for short " RA ") of existing 2G/3G, and the UE of existing 2G/3G will initiate Routing Area Update (Routing Area Update is called for short " RAU ") process at RA of every replacing.Certainly UE also has periodic position updating process under the situation of not changing RA, and its effect is to make network understand UE at present also at network, prevents the UE deviated from network but the constantly situation of the paging UE generation because network is not understood.Describe moving the network registration process that causes below owing to the position of UE.

Among Fig. 2, TA1, TA2, TA3, TA4 are the tracking areas of evolvement network, TA is similar to the RA of 2G/3G.When a multimode UE is mobile between different RA and TA, in order to guarantee in the network that adopts different RAT, all paging to arrive UE, UE need register in RA that moves to and TA, as UE when entering RA1, need be to the SGSN of 2G/3G registration, then need registration again when UE enters TA1, when UE moves out TA1 and reenters RA1, need again to the SGSN of 2G/3G registration to the MME/UPE of evolvement network.Yet this method causes frequent network registration process when guaranteeing paging, brought a large amount of register command expenses.

In order addressing this problem, in the specification document TR23.882 of 3GPP SAE, to have proposed some kinds of methods and avoided the frequent great waste of network registration process eating dishes without rice or wine to cause.A kind of scheme of basic at present establishment realizes reducing the UE of idle pulley in the influence of registration to eating dishes without rice or wine of adopting under the different RAT networks.The thinking of this scheme is that UE adheres to (attach) to the network post-registration to a kind of access network (2G/3G network or evolvement network), UE is registered to this another access network after moving to another access network more afterwards, like this, UE just has been registered to two kinds of connecting systems simultaneously, and UE need not initiate any registration process when mobile in the corresponding registration area (RA or TA) of these two networks afterwards.When changing RA or TA, UE to initiate common RAU process.The access entity of two kinds of connecting systems that UE is registered to (SGSN of 2G/3G or the MME of evolvement network) all has the context (context) of UE.

Below UE being attached to the register flow path that moves to again among the 2G/3G among the SAE earlier describes.

As shown in Figure 3, in step 301, UE is attached to SAE, sends attach request (adhering to request) message to MME.

Then, step 302 and step 302 ' in, MME is registered to HSS.(if the contextual information of existing this UE of MME then need not to obtain from HSS).

Then, in step 303, MME obtains context from HSS after, initiate verification process to UE.

Then, in step 304, the UE return authentication responds to MME.If authentication is passed through, UE is registered to the MME success, and MME distributes S-TMSI/S-RA and default IP (default bearing IP) information to UE.S-TMSI represents the Temporary Mobile Subscriber Identity of SAE, and S-RA represents the RA of SAE, i.e. TA.

Then, in step 305, MME/UPE confirms that UE adheres to successfully, allows the access of this UE, will distribute to the S-TMSI/S-RA of UE, also has the information of default bearing IP to send to this UE.

Then, in step 306, UE changes RAT behind 2G/3G, sends the RAU process, and the S-TMSI/S-RA that carries the MME distribution gives SGSN (may also will carry the parameters such as TMSI/RA that SGSN distributes).

Then, step 307 and step 307 ' in, SGSN initiates SGSN Context Request (SGSN context request) message to the MME of S-TMSI/S-RA correspondence and asks the context of UE; After MME receives this request message, related context is sent to this SGSN, we are referred to as Context Retrieval (context is recaptured) process this process.

Then, in step 308, may carry out verification process; SGSN may be registered to HSS, as step 309 and step 309 '.(may SGSN be registered to HSS yet, but SGSN with MME as HSS).

Then, in step 310, SGSN confirms context acceptance, may trigger the MME/UPE transferring data.

Then, step 311 and step 311 ' in, SGSN update packet data protocol (Packet DataProtocol, abbreviation " PDP ") context is to MME/UPE, because at user's face, MME/UPE is for the similar original gateway GPRS supporting node (GGSN) of SGSN (GPRS GatewaySupport Node is called for short " GGSN ").

Then, in step 312, SGSN distributes to UE with U-TMSI/U-RA and S-TMSI/S-RA, and UE moves between U-RA and S-RA needn't initiate registration updating message.U-TMSI represents the Temporary Mobile Subscriber Identity of 2G/3G, and U-RA represents the RA of 2G/3G.

Then, in step 313, UE returns the RAU process and finishes message.

UE is attached to the register flow path that moves to again among the 2G/3G among the SAE and UE earlier, and to be attached to the register flow path that moves to again among the 2G/3G among the SAE earlier similar, as shown in Figure 4, do not specify at this.

Briefly, UE at first is attached to SGSN, and SGSN is registered to HSS, and UE enters SAE more afterwards, initiate RAU, obtain context from SGSN, MME is registered to HSS, distributes S-RA/S-TMSI to UE, UE moves in RA that registers and S-RA and then need not initiate position renewal/registration message (under TA, RA notion afterwards, UE may distribute a plurality of zones at SAE or 2G/3G, as distributes several S-RA, and UE moves in the registration area of network allocation and needn't send out the phase renewal like this).Updating message then will be initiated in zone beyond UE moves to the S-RA/RA of registration.Need to prove that if in the process that UE moves, if SGSN does not change, then the registration process of SGSN may needn't be initiated.

In actual applications, there is following problem in such scheme: network side may be in unnecessary paging domain paging UE, reduced the paging efficiency of UE.

Cause the main cause of this situation to be, in present register flow path, UE registers after entering a kind of RAT network, the TA/RA that distributes this RAT network, after entering another kind of RAT network, initiate to upgrade, distribute the RA/TA of another kind of RAT network, UE moves in RA that registers and TA and needn't initiate to upgrade afterwards; When UE enters new RA or TA, then need to initiate to upgrade, it is related that SGSN/MME under the new RA/TA and the access entity (MME/SGSN) of another RAT network are set up, and UE needn't initiate renewal when mobile in the TA/RA of the access entity distribution of new RA/TA and another RAT network like this.

As shown in Figure 5, TA is the Acceditation Area of SAE, RA is the Acceditation Area of UMTS, according to existing scheme, UE is registered to MME when TA1, initiate the position renewal of UMTS and be registered to SGSN after entering RA1, between TA1 and RA1, move afterwards and needn't initiate more new technological process of position, having saved the mobile process of initiating the position renewal of table tennis between two RAT networks.(table tennis between TA1 and the TA2 between this RAT network avoid solve) by the TA notion.

After UE moves to RA2, initiate the position and upgrade, at this moment UE needn't initiate position updating process (when UE moves back to RA1 again, still will initiate the position and upgrade, UE mobile position of can not initiating between TA1 and RA1 is upgraded afterwards) mobile between TA1 and the RA2.

If UE moves between TA1 and RA2 and needn't initiate position updating process, and this UE moves to TA2 again from TA1, and then UE can initiate the position once more and upgrades, and UE moves between TA2 and RA2 and needn't initiate position updating process afterwards.

In like manner, when UE move to TA3, TA4 again, behind TA5, UE finally needn't initiate position updating process when mobile between TA5 and RA2.

But from the figure not difficult to find, UE is not at all in TA5 and the directly mobile possibility of RA2.In addition, possibly can't carrying out relatedly (as belongs to different Public Land Mobile Nerwork between the MME of management TA5 and the SGSN of management RA2, do not roam interface, or do not have the SGSN under the RA2 on because apart from reason, MME is last to be disposed " allowing related SGSN tabulation ").Therefore, needn't initiate signaling procedure between TA5 and the RA2.Because next step may enter TA5 zone on every side UE, and can not enter RA2, so the MME of the SGSN of RA2 and TA5 continues relatedly do not have too big meaning, if but still want paging RA2 zone during paging, to cause the amount of paging to increase, reduce the paging efficiency of UE.

Perhaps, in actual applications, UMTS is the network that all covers, and SAE is the network that focus covers, as shown in Figure 6.UE is after being registered to TA1 and RA1, and UE moves to RA2 to RA3 from RA1, and UE finally moves between TA1 and RA3 and needn't initiate to upgrade so; Perhaps UE is after being registered to TA1 and RA1, from TA1 move to TA2 to TA3 to TA4, so final UE moves between RA1 and TA4 and needn't initiate to upgrade.

Usually the registration area (after being registered to two RAT networks) with UE is called UE Acceditation Area or " exempting to upgrade the zone ", under the prerequisite of optimizations such as preferentially not being stationed, the paging zone of UE is exactly the Acceditation Area (" exempting to upgrade the zone ") of UE, but in fact because UE can directly not move (necessarily initiating processes such as position renewal in the moving process) in these two RA/TA, in fact the necessary paging zone of UE is the Acceditation Area of UE present located RAT network so.Therefore, make network side paging UE in unnecessary paging domain, reduced the paging efficiency of UE.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of method of mobile communication, mobile communication system and inserts entity, makes the paging efficiency of UE be improved.

For solving the problems of the technologies described above, the invention provides a kind of method of mobile communication, wherein, subscriber equipment is registered to the access entity at least two networks simultaneously, accepting respectively inserting of this user equipment registration, interrelated between the entity (address information that promptly writes down the other side's entity maybe can be derived the parameter of the address of the other side's entity, as TMSI, RAI), method comprises following steps:

Insert that entity upgrades in the position of carrying out subscriber equipment or during other access procedures,, then forbid in original related other network, inserting this subscriber equipment of paging in entity subordinate's the paging domain if predetermined condition is satisfied in the current zone of living in of this subscriber equipment.

The present invention also provides a kind of mobile communication system, comprises at least two networks, comprises respectively in each network to accept the access entity that same subscriber equipment is registered simultaneously, and each inserts between the entity interrelated, also comprises:

Judge module is used for inserting that position that entity carries out subscriber equipment is upgraded or during other access procedures, whether satisfying predetermined condition according to the current region decision of living in of this subscriber equipment;

Enable to change module, be used for judging when satisfying predetermined condition, forbid in original related other network, inserting calling user device in entity subordinate's the paging domain at judge module.

The present invention also provides a kind of access entity, comprises to be used for the relating module that related other networks are accepted the access entity that same subscriber equipment registers simultaneously, also comprises:

Judge module is used for whether satisfying predetermined condition according to the current region decision of living in of this subscriber equipment when the position renewal of carrying out subscriber equipment or other access procedures;

Enable to change module, be used for judging when satisfying predetermined condition, forbid in original related other network, inserting calling user device in entity subordinate's the paging domain at judge module.

By relatively finding, the main distinction of technical scheme of the present invention and prior art is, by inserting that entity upgrades in the position of carrying out UE or during access procedure, whether satisfy predetermined condition according to the current region decision of living in of this UE, if, then when this subscriber equipment of need paging, this UE of paging in the paging domain that inserts the entity subordinate forbids inserting this UE of paging in entity subordinate's the paging domain in original related other network.Wherein, predetermined condition can be the current zone of living in of this UE with original related other network in interval between access entity subordinate's the paging domain greater than presetting thresholding, or be non-adjacent zone; Also can be can't be related between the access entity in access entity and original other the related network in this current zone of living in of UE; Or UE reaches the thresholding time in current zone of living in, triggered by time or incident (upgrading mobile originating ticket MOC, mobile terminating ticket MTC etc. as the position).Avoid this UE of paging in the zone that UE can not occur, thereby made the paging efficiency of UE be improved.

Can be by the incidence relation of access entity in deletion and original related other network; Or the access entity is changed to released state with this UE in original other the related network of notice; Or change original incidence relation; Maybe insert in entity and original related other network the incidence relation between the access entity be set to invalid, only multiple mode such as this UE of paging forbids inserting this UE of paging in entity subordinate's the paging domain in original related other network in this access entity subordinate's paging domain, for realization of the present invention provides multiple mode.

Wherein, insert entity and can change original incidence relation in the following manner: this UE is registered in the access entity under other ICQ zones adjacent with the current zone of living in of this UE, this access entity is inserted entity as in new and other network that this access entity is associated, when needing this UE of paging, this UE of paging in the paging domain that inserts the entity subordinate and adjacent other ICQ zones.Make network side in the zone that UE may be in, carry out paging, further improved the paging efficiency of UE.

Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.

In the present invention, UE when mobile, needs register respectively in the access entity of two networks in adopting the network of different RAT, and these two to insert inter-entity interrelated.When UE moves to new TA or RA, initiate TAU (tracing section updating) or RAU (Routing Area Update) process or other access procedures (as service request service request, page response, periodic location update, activate PDP Context etc.) time, whether the access entity in this current zone of living in of UE satisfies predetermined condition according to the current region decision of living in of this UE, if, then when this subscriber equipment of need paging, this UE of paging in this access entity subordinate's paging domain forbids this UE of paging in another originally related access entity subordinate paging domain.Wherein, predetermined condition can be the current zone of living in of this UE with original related another access entity subordinate's paging domain between the interval greater than presetting thresholding, or be non-adjacent zone; Also can be that the access entity in this current zone of living in of UE inserts with this another can't be related between entity; Or UE reaches the thresholding time in current zone of living in, triggers this predetermined condition by time or incident (upgrading MOC, MTC etc. as the position).If the access entity in this current zone of living in of UE does not satisfy predetermined condition according to the current regional determination of living in of this UE, then when this UE of needs paging, this UE of paging in access entity subordinate's the paging domain in the access entity in this current zone of living in of UE and original related other network.

Because under TA, RA notion, UE may distribute a plurality of zones at SAE or 2G/3G, as distributes several S-RA, and UE moves in the registration area of network allocation and needn't send out the phase renewal like this, it is that example describes that the present invention distributes a RA or TA with each RAT network to UE, but does not limit.

Below first execution mode of the present invention is described in detail.Present embodiment relates to method of mobile communication, in the present embodiment, the access entity in the current zone of living in of UE insert the incidence relation of entity by deletion with original related another or notify this another insert entity this UE be changed to released state, forbid this UE of paging in another access entity subordinate's of original association paging domain.

Present embodiment moves to TA5 after being registered to RA2 (as Fig. 5) with UE always, enters into from TA4 that to initiate the TAU process behind the TA5 be example, and the handling process of the access entity MME in this current zone of living in of UE is described.

As shown in Figure 7, in step 701,, therefore initiate the TAU process, may carry S-RA in the updating message of TAU because UE enters new TA, S-TMSI, RA, TMSI or partial parameters wherein, the present invention does not limit these parameters.Wherein, S-TMSI represents the Temporary Mobile Subscriber Identity of SAE, and S-RA represents that the RA of SAE is TA, and TMSI represents the Temporary Mobile Subscriber Identity of UMTS network, and RA represents the RA of UMTS.

Then, enter step 702,, then should newly insert entity and may also need carry out context retrieval (context is recaptured) process if the access entity of new TA is the access entity of the unregistered mistake of this UE.That is to say, if the MME of the MME of the new TA that UE moves to and original registration is old MME, be not same MME, then should new MME need to old MME or/and SGSN or/and HSS obtains the contextual information of necessity.

Step 703 is processes such as optional safety certification.

Then, enter step 704, if the MME of the new TA that UE moves to is not same MME with original MME that registers, then this new MME may also need to initiate registration to HSS.

Then, enter step 705, new MME judges whether this UE present located zone satisfies predetermined condition.Such as new MME judges interval between this UE present located zone and original related another access entity subordinate's the paging domain whether greater than presetting thresholding, or is non-adjacent zone; Perhaps, whether can't be related between the access entity in this current zone of living in of UE and original another related access entity; Or UE reaches the thresholding time in current zone of living in or the speed in current zone of living in is lower than certain thresholding.That is to say, new MME judges whether the distance between TA5 and the RA2 (this RA2 is that the message that sends from this UE or recapture the process from context obtains) surpasses incidence relation between certain thresholding or non-conterminous or MME and the SGSN limited (as SGSN not in " can related SGSN tabulation " list of new MME) or UE and surpass certain thresholding a resident time of RAT and (be in a zone for a long time as UE, still to be in this regional probability be bigger to UE so, go to work in the Office Area as the user, or the sleep etc. of going home.Upgrading through the several times positions so, or other access procedures trigger, or Time Triggered, can use the present invention, as UE is gone association/go registration from another RAT zone, allow network not at other area pagings to save the paging resource.When UE moves to other RAT one zone once more, initiate registration again, rebulid association).Wherein, RA2 can recapture the process from the message of this UE transmission or from context and obtain.

If the distance between TA5 and the RA2 has surpassed the non-conterminous or new MME of certain thresholding and the incidence relation between the SGSN is limited or UE surpasses certain thresholding a resident time of RAT, then new MME initiates detach request (detach request) or association cancellation request message informing SGSN such as (the related requests of cancellation) is changed to UE separation (detach) state or removes to register this UE, or UE carried out tagging, this SGSN of mark does not need this UE is carried out paging.

Then, enter step 706, after SGSN receives this message, UE is changed to separation (detach) state or removes to register this UE, or UE is carried out tagging, this SGSN of mark does not need this UE is carried out paging.

Then, enter step 707, SGSN responds back to new MME.

Then, enter step 708, new MME cancels the incidence relation with originally related SGSN, promptly deletes the address information of this SGSN etc.

Then, may enter step 709, the current access entity of UE sends user's face notice of change to associated user's face equipment as anchor point between connecting system (IASA), forbids inserting entity by this IASA in other network and sends data or paging request.If MME and Anchor point are not nodes, and data send to SGSN and UPE by Anchor, and new MME sends message to the Anchor node, make Anchor no longer send data and only send to MME/UPE to SGSN.This step is different as the case may be and different, as can only setting up the tunnel of UPE to Anchor, and cancels the tunnel to SGSN; If data arrive SGSN and always pass through UPE, then MME sends notice to UPE, requires UPE no longer to send data to SGSN.Step 709 there is no precedence relationship with step 710.

In step 710, new MME sends TAU Accept (TAU finishes) message, this message only comprises the sign of SAE or gives the corresponding indication of this UE, when this UE enters new RA zone once more, use the SAE sign to initiate to insert, this is because the new SGSN that inserts can't obtain related context to old SGSN.

Be not difficult to find, in the present embodiment, do not have related possible when new access entity MME judges this MME with the access entity SGSN of original related another RAT network, or this UE present located zone TA5 to insert entity SGSN subordinate's paging zone RA2 non-conterminous or during at interval greater than thresholding necessarily with another, send the related request of detach request or cancellation, notifying another to insert entity SGSN is changed to this UE state of registering on it released state or removes to register this UE, or cancel two incidence relations that insert between the entity, make paging can in SGSN subordinate's paging zone, not initiate, avoid this UE of paging in the zone that UE can not occur, thereby made the paging efficiency of UE be improved.

Need to prove that it is SGSN that UE inserts entity in current zone of living in, situation and present embodiment that another RAT entity is MME are similar, do not repeat them here.

Second execution mode of the present invention relates to method of mobile communication, present embodiment moves to TA5 after being registered to RA2 (as Fig. 5) with UE equally always, enter into from TA4 that to initiate the TAU process behind the TA5 be example, the handling process of the access entity MME in this current zone of living in of UE is described.The difference of the present embodiment and first execution mode is, in the first embodiment, the access entity in the current zone of living in of UE insert the incidence relation of entity by deletion with original related another or notify this another insert entity this UE be changed to released state, forbid this UE of paging in another access entity subordinate's of original association paging domain.And in the present embodiment, the access entity in the current zone of living in of UE is forbidden this UE of paging in another originally related access entity subordinate paging domain by the change incidence relation.

Specifically, as shown in Figure 8, step 801 is identical to step 704 with step 701 respectively to step 804, does not repeat them here.

In step 805, new MME judges whether this UE present located zone satisfies predetermined condition.Such as new MME judges interval between this UE present located zone and original related another access entity subordinate's the paging domain whether greater than presetting thresholding, or is non-adjacent zone; Or UE is lower than certain thresholding a resident time of RAT above certain thresholding or speed; Perhaps, whether can't be related between the access entity in this current zone of living in of UE and original another related access entity.That is to say new MME judges whether the distance between TA5 and the RA2 (this RA2 is that the message that sends from this UE or recapture the process from context obtains) surpasses incidence relation between certain thresholding or non-conterminous or MME and the SGSN limited (as SGSN not in " can related SGSN tabulation " list of new MME).Wherein, RA2 can recapture the process from the message of this UE transmission or from context and obtain.

If the distance between TA5 and the RA2 has surpassed the non-conterminous or new MME of certain thresholding and the incidence relation between the SGSN is limited or UE surpasses certain thresholding a resident time of RAT, then new MME selects the affiliated access entity of the RA adjacent with TA5 as new another access entity that is associated with this access entity MME.Because a plurality of RAs adjacent with TA5 are arranged, therefore, can select the bigger adjacent area of probability that this UE may move to according to certain selection algorithm by new MME, i.e. this UE bigger RA of probability that may move to, or select a RA adjacent at random with TA5; Also can select the bigger RA of probability that this UE may move to according to certain selection algorithm, or select a RA adjacent at random, as the paging domain under the SGSN of new association of this UE with TA5 by another access entity SGSN of new association.

Therefore, in step 806, new MME sends position updating request to SGSN, carries adjacent RA such as the RA3 of TA5 that this MME selects; Perhaps new MME sends TA5 information, selects suitable R A by SGSN.

If the SGSN of the new association that new MME selects is not the SGSN of the original registration of UE, then may also need to carry out context and recapture process, make new SGSN obtain the context of this necessary UE, as step 807.

If the SGSN of the new association that new MME selects is not the SGSN of the original registration of UE, then should may also need to initiate registration by new related SGSN, as step 808 to HSS.

Then, in step 809, new related SGSN accepts the position and upgrades, and responds back to new MME.Rebulid MME to the incidence relation between the SGSN (be the SGSN address information that new MME is known new association, new related SGSN is known the address information of new MME), as step 809 '.

Then, in step 810, MME sends TAU Accept message, comprises the RA/TMSI sign (being RA3) of new UMTS, and afterwards, UE moves between TA5 and RA3 and needn't initiate to upgrade, and when this UE of need paging, will send paging in TA5 and RA3.

This shows, in the present embodiment, do not have related possible when new access entity MME judges this MME with the access entity SGSN of original related another RAT network, or this UE present located zone TA5 to insert entity SGSN subordinate's paging zone RA2 non-conterminous or during at interval greater than thresholding necessarily with another, initiatively this UE is registered on the access entity SGSN of its another adjacent RAT network, with the access entity of this SGSN as new association, should new related SGSN be that UE distributes new TMSI, and make UE in TA5 and RA3, needn't initiate to upgrade when mobile.When needing this UE of paging, (being TA5 and RA3) this UE of paging in new MME and new related SGSN subordinate's paging domain.Make network side in the zone that UE may be in, carry out paging, further improved the paging efficiency of UE.

The of the present invention the 3rd executes mode relates to method of mobile communication, present embodiment moves to TA5 after being registered to RA2 (as Fig. 5) with UE equally always, enter into from TA4 that to initiate the TAU process behind the TA5 be example, the handling process of the access entity MME in this current zone of living in of UE is described.The difference of the present embodiment and first execution mode is, in the first embodiment, the access entity in the current zone of living in of UE insert the incidence relation of entity by deletion with original related another or notify this another insert entity this UE be changed to released state, forbid this UE of paging in another access entity subordinate's of original association paging domain.And in the present embodiment, it is invalid that access entity by the current zone of living in of UE and incidence relation between original related another access entity are set to, forbid this UE of paging in another originally related access entity subordinate paging domain, when this UE of need paging, this UE of paging in the access entity subordinate's in this current zone of living in of UE paging domain only.Incidence relation be set to invalid be set to invalid with the cancellation incidence relation difference be, in the access entity in this current zone of living in of UE, still write down the address information of another related access entity etc., make UE in another inserts entity, still be in attachment state, but paging can not insert in the network of entity and sends this another.Certainly, MME may also can notify user's face interdependent node to make data can not be issued to another and insert entity.

Specifically, as shown in Figure 9, step 901 is identical to step 704 with step 701 respectively to step 904, does not repeat them here.

In step 905, new MME judges whether this UE present located zone satisfies predetermined condition.Such as new MME judges interval between this UE present located zone and original related another access entity subordinate's the paging domain whether greater than presetting thresholding, or is non-adjacent zone; Perhaps UE is lower than certain thresholding a resident time of RAT above certain thresholding or speed; Perhaps, whether can't be related between the access entity in this current zone of living in of UE and original another related access entity.That is to say new MME judges whether the distance between TA5 and the RA2 (this RA2 is that the message that sends from this UE or recapture the process from context obtains) surpasses incidence relation between certain thresholding or non-conterminous or MME and the SGSN limited (as SGSN not in " can related SGSN tabulation " list of new MME).Wherein, RA2 can recapture the process from the message of this UE transmission or from context and obtain.

If the distance between TA5 and the RA2 has surpassed the non-conterminous or new MME of certain thresholding and the incidence relation between the SGSN is limited or UE surpasses certain thresholding a resident time of RAT, then new MME mark is invalid with the incidence relation of original related SGSN, perhaps need to notify user entity UPE or this information of Anchor (anchor point), make UPE can not send data or paging to another RAT network.(may always arrive MME/UPE earlier as downlink data, insert the entity triggers predetermined condition when UE is current at SGSN, then SGSN need notify MME/UPE this information, UE still adheres at MME/UPE, but downlink data does not directly send to paging in SGSN and the paging domain SGSN subordinate in the evolvement network paging after arriving MME/UPE)

Then, enter step 906, new MME sends common TAU Accept message, because this UE can not move to RA2 from TA5, so this UE needn't have any modification.

If have downlink data or paging to arrive, because related invalid between the SGSN of new MME or UPE mark, so data or paging can not be dealt into SGSN, as step 907 and step 907 '.

Then, enter step 908, when this UE of needs paging, this UE of paging in SAE only, and carry out paging in needn't be in the UMTS corresponding RA2.Avoid this UE of paging in the zone that UE can not occur, thereby made the paging efficiency of UE be improved.

When this UE enters new RA zone, initiate RAU, as step 909 and step 909 '.

Then, enter step 910, carry out normal RAU process, as context recapture, register, process such as association.That is to say, when UE enters new RA, initiate RAU, if upgrading SGSN changes, then to MME or/and old SGSN asks for related context, MME and new SGSN set up new related, and new the SGSN whether invalid or cancellation association class of mark MME does not repeat them here like MME new among the present invention method whether mark SGSN is invalid or cancellation is related.If SGSN does not change, the then related recovery between MME and the SGSN.(also SGSN judges the association that need cancel to MME subsequently, then is similar to method of the present invention).

The of the present invention the 4th executes mode relates to method of mobile communication, idiographic flow as shown in figure 10, inserting entity with the current zone of living in of UE is SGSN, the situation that another RAT entity is MME describes for embodiment, certainly this method is applicable to that also it is MME that entity is inserted in the current zone of living in of UE, and another RAT entity is the situation of SGSN.

After satisfying limitation signaling deexcitation predetermined condition, just the interval between the current zone of living in of UE and original related MME subordinate's paging domain is greater than presetting thresholding, or is non-adjacent zone; Perhaps, can't be related between the access entity in this current zone of living in of UE and original another related access entity; Or UE reaches the thresholding time in current zone of living in or the speed in current zone of living in is lower than under the condition of certain thresholding, can insert time, the Event triggered (expiring) that triggers (upgrading or other accesses) or network by UE as timer as the position, be linked among the new SGSN, as step 1001.It is example that present embodiment triggers with the UE access network.

Then, entering step 1002, is not up-to-date if insert the Context (context) of entity, inserts entity and may also need carry out context retrieval (context is recaptured) process.

Step 1003 is processes such as optional safety certification.If inserting entity is new access entity, then this new SGSN may also need to initiate registration to HSS, as step 1004.

Then, enter step 1005, the relevant user entity of SGSN notice, should relevant user entity be anchor point between connecting system (IASA), be specially user entity (UPE), or 3GPP anchor point (3GPP Anchor), or SAE Anchor, or other gateway devices, after this associated user's face entity is notified, thereby forbid that sending data to another RAT has saved the paging of initiating at another RAT.Forbid that specifically the method to another RAT transmission data is that this relevant user entity carries out mark, perhaps be discharged into the tunnel of another RAT entity (being UPE in this example), or only be established to the tunnel that inserts entity (being SGSN in this example).

Then, enter step 1006, SGSN writes down this deexcitation information, sends these data or paging request to another RAT entity after preventing to receive data.This step is an optional step.

The 5th execution mode of the present invention relates to mobile communication system, comprises to accept the access entity that same subscriber equipment is registered simultaneously at least in two networks, and each inserts between the entity interrelated.In addition, also comprise: judge module is used for whether satisfying predetermined condition according to the current region decision of living in of this UE when inserting entity at the position renewal of carrying out UE or access procedure; Enable to change module, be used for judging when satisfying predetermined condition, forbid in original related other network, inserting this UE of paging in entity subordinate's the paging domain at this judge module.
