Description

The method of user facility to attach to network and system thereof
Technical field
The present invention relates to wireless communication field, particularly the technology of user facility to attach to network.
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 ") wait digital mobile communication technological (2G), 3G to be 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; The network architecture and the agreement of existing third generation partner program (3rd Generation Partnership Project is called for short " 3GPP ") 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 (User Equipment is called for short " UE ") access network, basic IP connection need be 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 on above basis, deriving out is 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 plane 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, tracking area (Tracking Area is called for short " TA ") information etc.; And the user carried out authentication; It is corresponding to the control plane part of current UMTS (Universal Mobile Telecommunications System is called for short " UMTS ") 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 UE under the idle condition is initiated paging, and the interior routing iinformation of context, IP bearing parameter and network of UE etc. is preserved in management, and it is corresponding to the datum plane part of the inner SGSN of current UMTS; The user plane anchor point can comprise 3GPP anchor point (3GPP Anchor) and SAE anchor point (SAE Anchor); 3GPP Anchor is the user plane anchor point between different access systems in the 3GPP system, and SAE Anchor is the user plane anchor point between 3GPP connecting system and non-3 GPP system among the SAE.The user plane 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 (ControlPlane Server is called for short " CPS "), logically can be with it as Long Term Evolution radio access network entity (LTE-RAN Entity).
In practical application; Above evolvement network can be network coexisted with existing 2G/3G, therefore possibly exist simultaneously to adopt the different radio access technologies network configuration of (Radio Access Technology is called for short " RAT "); In this network configuration; UE need move (like 2G/3G network and evolvement network) between different RAT, in the process that moves, may quarter at various network and rattle and cause network registration process owing to UE changes.As shown in Figure 2, RA1 and RA2 are the route district (Routing Area is called for short " RA ") of existing 2G/3G, and UE will initiate Routing Area Update (Routing Area Update is called for short " RAU ") process at RA of every replacing in the existing 2G/3G network.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 in the face of moving the network registration process that causes down owing to the position of UE.
Among Fig. 2, TA1, TA2, TA3, TA4 are the tracking areas of evolvement network, are similar to the RA of 2G/3G network.When a multimode UE moves 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,, when getting into RA1, need register to the SGSN of 2G/3G like UE; When UE gets into TA1 then again need be to the MME/UPE/ of evolvement network anchor point (Anchor) registration, when UE moves out TA1 and gets into RA1 again, need again to the SGSN of 2G/3G registration.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 significant wastage of network registration process eating dishes without rice or wine to cause.A kind of scheme of basic at present establishment is mainly used in registration the influence to eat dishes without rice or wine of UE under the different RAT networks of employing that reduces idle pulley.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, need not initiate any registration process when UE moves in the corresponding registration area (RA or TA) of these two networks afterwards., UE to initiate common RAU process when changing RA or TA.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.
In the face of being attached to the register flow path that moves to again in the 2G/3G network among the evolvement network SAE earlier, UE describes down.
As shown in Figure 3, in step 301, UE is attached to SAE, sends attach request (attach request) message to MME.
Then, step 302 and step 302 ' in, MME is registered to HSS, obtains the contextual information of UE, if the contextual information of existing this UE of MME then need not from HSS, to obtain.This step also can after accomplish.
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 SAE Temporary Mobile Subscriber Identity (SAE TemperateMobile Subscription Identity is called for short " S-TMSI ")/S-RA and default bearing IP (defaultIP) information to UE.S-RA is the RA of SAE, i.e. TA.
Then, in step 305, MME/UPE/Anchor confirms UE attach success, allows the access of this UE, with the S-TMSI/S-RA that distributes to UE, also has the information of default bearing IP to send to this UE.
Then, in step 306, UE moves to 2G/3G network (having changed RAT), initiates the RAU process, and the S-TMSI/S-RA that carries the MME distribution gives SGSN.
Then, step 307 and step 307 ' in, SGSN initiates SGSN Context Request (SGSN context request) message to the corresponding MME of S-TMSI/S-RA 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, possibly carry out verification process; SGSN may be registered to HSS, as step 309 and step 309 '.(maybe SGSN be registered to HSS yet, but SGSN with MME as HSS).
Then, in step 310, SGSN confirms context acceptance, possibly trigger the MME/UPE/Anchor transferring data.
Then; Step 311 and step 311 ' in; SGSN update packet data protocol (Packet DataProtocol is called for short " PDP ") context is to MME/UPE/Anchor, because in user plane; MME/UPE/Anchor is as far as the similar original gateway GPRS supporting node (GGSN) of SGSN (GPRS Gateway Support 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 representes the Temporary Mobile Subscriber Identity of 2G/3G network, and U-RA representes the RA of 2G/3G network.
Then, in step 313, UE returns the RAU process and accomplishes message.
UE is attached to the register flow path that moves to again in the 2G/3G network among the SAE and UE earlier, and to be attached to the register flow path that moves to again in the 2G/3G network 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; UE gets into SAE more afterwards, initiates RAU, obtains context from SGSN; MME is registered to HSS, distributes S-RA/S-TMSI to UE, and UE moves in RA that registers and S-RA and then need not initiate position renewal/registration message afterwards.When UE moves to the zone beyond the S-RA/RA of registration, then to initiate updating message.Need to prove, in the process that UE moves, if SGSN does not change, then in this flow process needn't initiation SGSN registration process.
In practical application, prior art exists following problem: UE to adhere in the process of UMTS network possibly exist unnecessary operation, has increased the complexity of UE attach to network.
Cause the main cause of this situation to be, in the prior art, when UE adheres to UMTS earlier and adheres to evolvement network again, adhere in the process of UMTS network, need set up default bearing, promptly need initiate the activation of PDP Context for evolvement network at UE; But be not that all UE need carry out such processing, under following situation, need do not carry out the activation of PDP Context:
Do not support the UE of evolvement network pattern, like UMTS single mode UE;
The UE that does not have the evolvement network access demand can be provided with by the user like bimodulus UE, when the user hopes cost saving, can UE used when inserting UMTS as single mode through setting;
The UE that SAE is limited does not allow the user to use evolvement network like user signing contract information, although the user uses bimodulus UE, Network Check UE is the evolvement network limited users, can not use evolvement network; Perhaps the residing zone of UE is a SAE confined area etc.;
Network does not have evolvement network access capability or limited, as the UMTS network of some operator do not dispose evolvement network or part SGSN and evolvement network do not have interface or and the evolvement network entity between can't connect;
Under above situation, in the process of UE attach to network, it is meaningless as far as UE to carry out pdp context activation, and has increased UE and the unnecessary signaling process of network side, has increased the complexity of UE attach to network, has reduced the speed of UE attach to network.
Summary of the invention

Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that the present invention is done to describe in detail further below.
Among the present invention; In the process of UE attach to network; If this UE and/or network side do not satisfy the primary condition of UE cut-in evolution network; Be the ability that UE does not have authority that the ability of cut-in evolution network or demand that UE does not have cut-in evolution network or UE do not have cut-in evolution network or network side not to have cut-in evolution network, then forbid carrying out pdp context activation.Make the UE that does not need maybe to use evolvement network when attach to network, can simplify handling process, reduce network side and the unnecessary operation of UE side.
Describe in the face of first embodiment of the invention down, first embodiment of the invention relates to the method for UE attach to network.In this execution mode; UE is according to self evolvement network access capability and/or evolvement network access demand; When ability that cut-in evolution network is arranged self and demand; In the attach request (attach request message) of sending, carry subsequent request sign (follow on request sign), represent follow-up other signalings that has to SGSN.Network side confirms according to this sign whether UE has needs to carry out subsequent operation.
Specifically as shown in Figure 5; In step 501; UE sends attach request to the SGSN of network side, in this attach request, carries the evolvement network access capability information of UE, if this UE has the ability and the demand of cut-in evolution network; Then also in this attach request, carry the subsequent request sign, the indication network side does not discharge current connection after returning attachment response (Attach Accept).
Alternatively, in step 502, the safety certification process that SGSN can carry out.
Alternatively, in step 503, SGSN is to the HSS registration (also possibly register to MME) of this UE.If in this HSS, register before this SGSN, then this step can be omitted.
SGSN confirms according to the attach request of UE whether this UE has the demand of cut-in evolution network; If do not carry the subsequent request sign in this attach request; Represent that then this UE does not have the demand of cut-in evolution network; Then get into step 505, SGSN directly returns attachment response (Attach Accept) to UE, in this attachment response, does not carry out of Memory.After this UE receives this attachment response, the PDP context activation request of not redispatching.SGSN can directly discharge with this UE between be connected.Make the UE need not use evolvement network when attach to network, can simplify handling process, avoid network side and UE side to carry out relevant ability and judge, or carry out other and the relevant unnecessary operation of evolvement network, the speed of quickening UE attach to network.
If carry the subsequent request sign in this attach request; Represent that then this UE has the demand of cut-in evolution network; Then get into step 504; SGSN checks that further the evolvement network access capability of network side and/or the evolvement network of UE insert restriction, and/or confirms according to the access capability information of this UE in the attach request whether this UE has the ability of cut-in evolution network.Have the ability of cut-in evolution network if confirm network side, and UE has the authority and the ability of cut-in evolution network, then get into step 506; Otherwise; If this UE has the demand of cut-in evolution network, but the SGSN inspection confirms that this UE does not have the authority of cut-in evolution network or do not have the ability of cut-in evolution network or the ability that network side does not have cut-in evolution network, then gets into step 505 equally; SGSN returns attachment response to UE; In this attachment response, do not carry out of Memory, thereby avoid modification, or carry and forbid that UE initiates the sign of pdp context activation SGSN.After indicating this UE to receive this attachment response, needn't send the PDP context activation request.SGSN can directly discharge with this UE between be connected.Make when UE or network side do not possess the primary condition of cut-in evolution network, can avoid carrying out other and the relevant unnecessary operation of evolvement network, simplify handling process, accelerate the speed of UE attach to network.
In step 506; SGSN confirms that this UE has demand, ability and the authority of cut-in evolution network, and network side has the ability of cut-in evolution network, so SGSN returns attachment response to UE; In this attachment response, carrying indication allows UE to initiate the sign of pdp context activation; Accept sign like subsequent request, the expression network side allows this UE to carry out the subsequent operation of cut-in evolution network, current do not discharge with this UE between be connected.Then get into step 507.
In step 507, after UE receives this attachment response, confirm that according to the sign of wherein carrying network side allows to carry out the activation of PDP Context, in this step, UE sends the PDP context activation request to SGSN.
SGSN waits for the follow-up signaling behind the UE, i.e. the PDP context activation request of UE is after receiving this activation request; Get into step 508, SGSN creates PDP Context, is established to the carrying of evolvement network; Like the carrying between SGSN and the MME, accomplish this pdp context activation.
After pdp context activation is accomplished, then get into step 509, SGSN sends PDP context activation success response message to UE, notifies this UE the current activation of having accomplished PDP Context, successfully the default bearing between foundation and the evolvement network.
The second embodiment of the invention and first execution mode are roughly the same; Its difference is; In the first embodiment, SGSN tested to the evolvement network access capability of UE and/or the evolvement network access capability of access authority and/or network side before returning attachment response; Have the ability and the authority of cut-in evolution network at definite this UE; And after network side has the ability of cut-in evolution network, in the attachment response of returning, carry indication and allow UE to initiate the sign of pdp context activation, otherwise in this attachment response, do not carry redundant information or carry the sign of forbidding UE initiation pdp context activation.
And in this execution mode, when UE has the demand of cut-in evolution network, promptly in the attach request that UE sends, carry under the situation of subsequent request sign, SGSN unconditionally receives this subsequent request, returns attachment response to UE.After UE receives this attachment response, send the PDP context activation request to SGSN.Network side is after receiving this activation request; Just the evolvement network access capability of UE and/or the evolvement network access capability of access authority and/or network side are tested, if confirm that this UE has the ability and the authority of cut-in evolution network, and network side has the ability of cut-in evolution network; Then accomplish this pdp context activation; Carrying between foundation and the evolvement network, otherwise forbid accomplishing this pdp context activation, return corresponding PDP context activation failure response message to UE.
Because the demand that whether UE has a cut-in evolution network in this execution mode is sent subsequent request through UE and is identified and represent, when SGSN receives the subsequent request sign, does not discharge connection usually, waits for that UE continues to send signaling.Therefore; Can in pdp context activation, carry out evolvement network access capability or the access capability of UE or the judgement of authority of network side, realize relevant treatment according to judged result, in this method; Though UE still need send the PDP context activation request under uncertain situation; But owing to time of SGSN being carried out correlated judgment and the time of waiting for the request of reception PDP context activation integrate, thereby reduced the required time of UE attach to network, accelerated to adhere to speed.
In addition; In practical application; Because Non-Access Stratum signaling (Non-Access Stratum is called for short " NAS ") is type lengths values (Type Length Value is called for short " TLV ") form; The information SGSN that bimodulus UE sends do not upgrade (not carrying out the upgrading of evolvement network access capability) though can't discern, can not make a mistake yet; If SGSN did not upgrade, explain that network side does not have the evolvement network access capability, UE can not receive extraneous information in attachment response, and then UE can not send the PDP context activation request.
Describe in the face of third embodiment of the invention down; The 3rd execution mode relates to the method for UE attach to network; Roughly the same with first execution mode, its difference is, in the first embodiment; UE is through carrying the subsequent request sign in attach request; This UE of informing network side has the ability and/or the demand of cut-in evolution network, when SGSN comprises this subsequent request sign in the attach request of receiving, the evolvement network access capability of this UE or the ability of authority or network side cut-in evolution network is judged; If do not comprise this subsequent request sign, then need not to carry out corresponding judgement, directly return attach request, in this attach request, do not comprise any information, after UE receives this attach request, can not initiate the PDP context activation request.
And in this execution mode; UE is when initiating attach request; Directly carry evolvement network access capability and/or the access demand information of this UE, judge according to these information, if confirm that UE has ability, demand and the authority of cut-in evolution network by SGSN; And network side has the ability of cut-in evolution network, then in attachment response, carries to require this UE to initiate the indication of pdp context activation; Otherwise forbid carrying this indication.UE if wherein carry this indication, then sends the PDP context activation request to SGSN, otherwise forbids sending the PDP context activation request after receiving attachment response.
Specifically as shown in Figure 6, in step 601, UE initiates attach request to SGSN, in this attach request, carries evolvement network access capability and/or the access demand information of this UE.
Alternatively, in step 602, the safety certification process that SGSN can carry out.
Alternatively, in step 603, SGSN is to the HSS registration (also possibly register to MME) of this UE.If in this HSS, register before this SGSN, then this step can be omitted.
Then get into step 604, SGSN tests to the evolvement network access capability of UE and/or the evolvement network access capability of access demand and/or access authority and/or network side.
Then get into step 605, SGSN returns attachment response to UE.If in step 604; SGSN confirms that this UE has the ability of cut-in evolution network, demand and authority; And network side has the ability of cut-in evolution network, then in this step, in attachment response, carries the indication that requires this UE initiation pdp context activation; Otherwise in this step, forbid carrying and require this UE to initiate the indication of pdp context activation, and directly discharge with UE between be connected.Make when UE or network side do not possess the primary condition of cut-in evolution network, can avoid carrying out other and the relevant unnecessary operation of evolvement network, simplify handling process, accelerate the speed of UE attach to network.In Fig. 6, require this UE to initiate the example that is designated as of pdp context activation to carry in the attachment response.Then get into step 606.
Then get into step 606; After UE receives this attachment response,, confirm whether network side requires to carry out the activation of PDP Context according to the sign of wherein whether carrying; If do not carry this sign; Then UE no longer initiates pdp context activation, if carry this sign, then UE sends the PDP context activation request to SGSN.
SGSN waits for the follow-up signaling behind the UE, i.e. the PDP context activation request of UE is after receiving this activation request; Get into step 607, SGSN creates PDP Context, is established to the carrying of evolvement network; Like the carrying between SGSN and the MME, accomplish pdp context activation.
After pdp context activation is accomplished, then get into step 608, SGSN sends PDP context activation success response message to UE, notifies this UE the current activation of having accomplished PDP Context, successfully the default bearing between foundation and the evolvement network.
What deserves to be mentioned is, in this execution mode, network side can but might not in the attachment response message of returning to UE, carry and require this subscriber equipment to initiate the indication of pdp context activation; Also can require this subscriber equipment to initiate pdp context activation through send independently message to UE.
Four embodiment of the invention relates to the method for UE attach to network; In this execution mode; Network side is in advance through broadcast, and the evolvement network access capability information of network side is sent to UE, and UE is after definite network side has the ability of cut-in evolution network;, in attach request, carry the subsequent request sign according to the demand of self.About system broadcast message, generally be to broadcast through operation and maintenance (Operation andMaintenance is called for short " O&M ") notice RAN.Specifically as shown in Figure 7.
In step 701, UE at first confirms the evolvement network access capability of network side according to broadcast.UE monitors this broadcast; In this broadcast, do not comprise the evolvement network access capability information of network side or comprise the indication network side when not having the information of ability of cut-in evolution network; Confirm that network side does not have the ability of cut-in evolution network; UE comprises the evolvement network access capability information of network side or comprises the indication network side when having the information of ability of cut-in evolution network in the broadcast of being monitored, confirm that network side has the ability of cut-in evolution network.
Then get into step 702; UE sends attach request to the SGSN of network side, in this attach request, carries the evolvement network access capability information of UE, if this UE has the ability and the demand of cut-in evolution network; And UE confirms that network side has the ability of cut-in evolution network; Then also in this attach request, carrying UE has the ability of cut-in evolution network and the information of demand, and like the subsequent request sign, the indication network side does not discharge current connection after returning attachment response.Issue the network side ability information through broadcasting, make UE know that as early as possible this UE whether can cut-in evolution network, avoid when not satisfying the primary condition of cut-in evolution network, send the unnecessary information of carrying that obtains.
Alternatively, in step 703, the safety certification process that SGSN can carry out.
Alternatively, in step 704, SGSN is to the HSS registration (also possibly register to MME) of this UE.If in this HSS, register before this SGSN, then this step can be omitted.
If carry the subsequent request sign in this attach request, then then get into step 705, SGSN tests to evolvement network access capability and/or the access authority of UE, gets into step 706 afterwards; Otherwise directly get into step 706, need not to carry out corresponding judgement.
In step 706, SGSN returns attachment response to UE.If in step 705, SGSN confirms that this UE has the ability and the authority of cut-in evolution network, then in this step, in attachment response, carries indication and allows this UE to initiate the sign of pdp context activation; Otherwise, if do not comprise the subsequent request sign in this attach request, or in step 705; SGSN confirms that this UE does not have the ability or the authority of cut-in evolution network; Then in this step, forbid in attachment response, carrying this indication, and directly discharge with UE between be connected.Make when UE or network side do not possess the primary condition of cut-in evolution network, can avoid carrying out other and the relevant unnecessary operation of evolvement network, simplify handling process, accelerate the speed of UE attach to network.In Fig. 7, the ability and the authority that have cut-in evolution network with this UE are example.Then get into step 707.
In step 707, after UE receives this attachment response, confirm that according to the sign of wherein carrying network side allows it to carry out the activation of PDP Context, in this step, UE sends the PDP context activation request to SGSN.
SGSN waits for the follow-up signaling behind the UE, i.e. the PDP context activation request of UE is after receiving this activation request; Get into step 708, SGSN creates PDP Context, is established to the carrying of evolvement network; Like the carrying between SGSN and the MME, accomplish pdp context activation.
After pdp context activation is accomplished, then get into step 709, SGSN sends PDP context activation success response message to UE, notifies this UE the current activation of having accomplished PDP Context, successfully the default bearing between foundation and the evolvement network.
In this execution mode; When UE has demand and the UE of cut-in evolution network to confirm that network side has the ability of cut-in evolution network; Promptly in the attach request that UE sends, carry under the situation of subsequent request sign; SGSN can unconditionally receive this subsequent request equally, returns attachment response to UE, does not discharge connection.After UE receives this attachment response, send the PDP context activation request to SGSN.Network side is after receiving this activation request; Just evolvement network access capability and/or the access authority of UE are tested; If confirm that this UE has the ability and the authority of cut-in evolution network, then accomplish this pdp context activation, the carrying between foundation and the evolvement network; Otherwise forbid accomplishing this pdp context activation, return corresponding PDP context activation failure response message to UE.
Fifth embodiment of the invention and the 4th execution mode are roughly the same; Its difference only is; In this execution mode; UE is at the evolvement network access capability of confirming network side according to broadcast, and this UE is when having ability and the demand of cut-in evolution network, the access capability and the access demand information of directly in attach request, carrying UE.If SGSN does not obtain these information from attach request, then directly return attachment response, in this response, do not carry any information, and directly discharge relevant connection; Otherwise, then judge according to these information, if confirm that UE has ability, demand and the authority of cut-in evolution network, then in attachment response, carry the indication that requires this UE initiation pdp context activation; Otherwise forbid carrying this indication.UE if wherein carry this indication, then sends the PDP context activation request to SGSN, otherwise forbids sending the PDP context activation request after receiving attachment response.
Sixth embodiment of the invention relates to a kind of system of UE attach to network, comprises network side and UE, also comprises: be used for the process at the UE attach to network, judge whether this UE and/or network side satisfy the judging unit of the primary condition of UE cut-in evolution network; Be used for when not satisfying the primary condition of UE cut-in evolution network, forbid carrying out the unit of forbidding of pdp context activation.Make when UE or network side do not possess the primary condition of cut-in evolution network, can avoid carrying out other and the relevant unnecessary operation of evolvement network, simplify handling process, accelerate the speed of UE attach to network.
Wherein, the primary condition of UE cut-in evolution network is one of following or its combination in any:
