Description
Technical field
The present invention relates to packet domain and evolution territory thereof in the mobile communcations system, particularly the terminal a kind of method and the terminal that are linked into its evolution domain system and register by grouping domain system.
Background technology
Since the cellular communication system invention, Radio Transmission Technology has obtained significant progress, from the artificial antenna technical development of the first generation to the digital radio technology of the second generation, and invented digital mobile communication system GSM (Global System for Mobile Communications), gsm system mainly provides speech business, and the flank speed of data is 9.6kb/s.
GPRS (General Packet Radio Service) is a kind of mobile pocket data business based on GSM, and user oriented provides the IP that moves grouping or X.25 connects.Gprs system is based on packet-switch technology, and the user can use various high-speed data services by GPRS under mobile status.The speed theoretical value that GPRS provides is 171.2kb/s.Still in development, this access technology is called as GERAN (GSM EDGE Radio Access Network) to GPRS at present.
UMTS (Universal Mobile Telecommunication System, universal mobile telecommunications system) is the third generation radio digital communication system that 3GPP (3rd Generation Partnership Project, third generation partner program) proposes.Replaced Gb mouth based on the Iu_PS mouth of ATM based on frame relay, air interface has replaced the GSM technology by WCDMA (the Wideband Code Division MultipleAccess) technology based on Frequency Division Duplexing (FDD), therefore UMTS can provide higher speed than GPRS, to support multimedia service and internet browsing.UMTS can provide the message transmission rate up to 2Mb/s.Radio Access Network is called as UTRAN (Universal Terrestrial Radio AccessNetwork, global system for mobile communications wireless access network) among the UMTS.GERAN and UTRAN all can be linked into the core net of UMTS.The framework of UMTS as shown in Figure 1, network element wherein has:
RAN (Radio Access Network): wireless access network, terminal is by the packet-based core networks (Packet Core) of RAN access UMTS, and RAN comprises UTRAN and GERAN.
SGSN (Serving GPRS Support Node): Serving GPRS Support Node, preservation user's route zone position information is responsible for safety and access control.SGSN links to each other with UTRAN by the Iu mouth, links to each other with GERAN by the Gb mouth.
GGSN (Gateway GPRS Support Node): gateway support node, be responsible for the IP address of distributing terminals and, link to each other with SGSN inner to the gateway function of external network.
HLR (Home Location Register): attaching position register, preserve user's the subscription data and the SGSN address at current place.
PDN (Packet Data Network): packet data network, for the user provides packet-based service network.
After IMS introduces 3GPP, can provide more multimedia service by the mobile network, these service needed networks provide higher rate and shorter propagation delay time.In addition along with the sudden emergence of non-3GPP wireless access technology, as WLAN (Wireless Local Area Network, WLAN (wireless local area network)), WiMAX (World Interoperability for Microwave Access, global microwave access intercommunication) etc., these technology can provide higher access bandwidth on the one hand, cost is more and more lower on the other hand, and the access technology (UTRAN/GERAN) to original 3GPP has caused very big threat like this.Therefore the 3GPP tissue has begun the research to UTRAN among the UMTS and Packet Core next stage evolution.The problem of this research is called SAE (System Architecture Evolution, System Architecture Evolution), purpose is to make the wireless communication system of evolution that higher transmission rate can be provided, shorter transmission delay, lower cost, support the mobility between the inner connecting system of 3GPP simultaneously, and the mobility between 3GPP connecting system and the non-3GPP connecting system.
The framework of SAE as shown in Figure 2 at present.Wherein Xin Zeng network element has:
E-RAN (Evolved RAN): the wireless access network of evolution is follow-on wireless access network, and higher up-downgoing speed can be provided, lower transmission delay and reliable more wireless transmission.
MME (Mobility Management Entity): chain of command functional entity, be in charge of and store the UE context (such as the UE/ user ID, mobility management states, user security parameters etc.), for the user distributes temporary mark, when quartering at this tracing area or this network, is responsible for UE this user is carried out authentication.
UPE (User Plane Entity): the user plane functions entity, the user face data route is handled, and termination is in the downlink data of the UE of idle state, when the downlink data that mails to UE arrives, initiates paging.The context of management and storage UE is such as IP bearer service parameter and network internal routing iinformation etc.
IASA (Inter Access System Anchor): the anchor point of different access systems, the different IASA of being of it and UPE are responsible for the distribution of the IP address of the overall situation.Be different connecting systems, comprise the mobility anchor point of 3GPP and non-3GPP connecting system.
No matter be, with three kinds of states are arranged per family: released state, idle condition and connection status at UMTS or at SAE.Under the released state, network is not known user's current position information; Under idle condition, do not have connection between user and the network, but network is known user's current position information, is RA (Routing Area, route district), is TA (Tracking Area, tracking area) in UMTS in SAE; Under connection status, exist between user and the network to connect.
The problem that SAE is studying at present is, under idle condition, and the mobility of terminal between UMTS and two kinds of connecting systems of SAE.The construction of considering SAE is on the basis that UMTS covers, and at first can carry out local covering.Under idle condition, dual-mode terminal may change between these two access waies back and forth like this.If there is not relative measures to avoid this situation, what UE will not stop registers between two kinds of access waies, thereby takies the on-air radio resource greatly.3GPP is studying corresponding solution, when the user changes access way, can initiate enrollment process.Basic thought has three, first method be exactly when the user when UMTS registers, SGSN need remove to upgrade MME, like this when dual-mode terminal when UMTS is transferred to SAE, because the user had registered at MME, so UE can not be used in SAE initiation enrollment process.Second method is exactly that the user registers in SGSN earlier, and SGSN goes HSS (home subscriber server) to register and obtain the user data of UMTS and SAE.When the user when SAE registers, MME goes SGSN to obtain the user data of SAE.When the user changes access way again, just do not needed attaching process.The 3rd method is exactly that the user registers among MME from SAE earlier, and MME goes HSS to obtain user data, when the user changes to UMTS, does not need to initiate attaching process, and when initiating business from UMTS, SGSN need be established to user's face of MME/UPE.
The shortcoming of first kind of scheme has: must increase the signaling of registering between SGSN and the MME, revise bigger to original SGSN, to HLR and MAP (Mobile Application Part, MAP) modification is all arranged, and when from SGSN to MME, going to register, be not set up user's face, like this and be linked into the MME inconsistently from E-RAN, increased the complexity of MME network element.For second and the third scheme, SAE user data and UMTS user data must send to SGSN or MME together among the HSS, revise bigger to HLR and SGSN.Therefore these three kinds of schemes are all infeasible, at present also good without comparison solution.

Embodiment
Fig. 3 is the system architecture diagram that present embodiment UMTS inserts SAE.Among the figure, UMTS and SAE use same user ID, but the authentication parameter of the two can be independent.The SGSN of UMTS inserts MME by the S3-C interface, and this interface is only as command transmitting; Insert UPE by the S3-U interface, this interface is only as the transmission data.Wherein, MME, UPE can unify, and also can separate.If unification, the S10 interface is exactly an internal interface so.UPE and IASA also can unify or separately, if unification, the S5 interface is exactly an internal interface so.
Dual-mode terminal UE of the present invention must have UMTS module and SAE module simultaneously, and the SAE module can be after UMTS adheres to first, utilize PDP (the Packet DataProtocol of UMTS module, packet data protocol) context activation process, and preserve the SAE register information that UMTS returns, comprise user's temporary mark S-TMSI, the tracking area TAI of registration and IP address etc.
To be present embodiment dual-mode terminal UE insert SAE and carry out the flow chart of register method by UMTS Fig. 4, and this UE also not in UMTS and SAE registration, may further comprise the steps:
Step 401, dual-mode terminal UE initiates attaching process from UMTS, this adheres to request and sends to SGSN by RAN, carries user ID IMSI (International MobileSubscriber Identity) and current Routing Area Identifier RAI (Routing Area Identity) in the Attach Request message;
Step 402 after SGSN receives Attach Request message, is obtained authentication information according to IMSI from HLR, and the user is carried out authentication;
Step 403, after the authentication success, SGSN initiates the SGSN enrollment process to HLR, sends the SGSN register request message;
Step 404, HLR initiates to insert UMTS user data process to SGSN;
Step 405 is inserted after the user data success, and HLR preserves the SGSN address, returns SGSN registration request response then;
Step 406, SGSN preserves RAI after receiving the registration request response of HLR, and allocation packets territory casual user identifies P-TMSI (Packet-Temporary Mobile Subscriber Identity), send to adhere to UE and accept message, carry P-TMSI and RAI in this message;
Step 407, the UMTS module of UE receive to adhere to and accept after the message, preserves P-TMSI and RAI, and return to SGSN and adhere to and finish, and notice SGSN successfully receives the P-TMSI of distribution, and attaching process finishes;
This attaching process is consistent with existing procedure.
Step 408, UMTS adheres to after the success, the UMTS module continues to initiate pdp context activation, the UMTS module sends the PDP context activation request to SGSN, carry the identification information that needs to insert SAE in the message, the APN (Access Point Name, access point name) that present embodiment is adopted as this kind service contract represents, but also can adopt the character or the information unit of other agreement, perhaps SGSN adopts alternate manner to decide needs to insert SAE.
The UMTS module can be to notify the SAE module after adhering to success, and UMTS continues to initiate the PDP context activation request by this SAE module notice.Also can be to carry out communication by SAE module and UMTS module when start, after the UMTS module learnt that the SAE module exists, the direct PDP Context of initiating in back swashs process adhering to successfully.
Step 409, after SGSN receives PDP context activation message and learns that need insert SAE, search or pass through default configuration by APN, obtain certain MME address among the SAE, initiate to create the PDP Context request to this MME then, have the tunnel information of Routing Area Identifier RAI or tracking area identification TAI, user ID, APN, SGSN distribution etc. in this request message, enter step 410.
In the present embodiment, SGSN judges whether that according to APN needs are linked into SAE, need be linked into SAE as finding, then this APN is carried out DNS (Directory Name Service, domain name service) and searches, and perhaps by the default configuration on the SGSN, finds certain MME.
SGSN also can derive RAI corresponding TAI earlier, selects a suitable MME according to this TAI then.If can not derive TAI, will select a MME to send so arbitrarily and create the PDP Context request, be not with TAI or RAI.After MME received, judging did not have TAI/RAI, then directly enters step 413 then.
Step 410, MME receives and creates after the PDP Context request message, as allows this SGSN to insert, the TAI that derives according to RAI is within this MME control range, and judge that this locality does not have the SAE user data, then trigger the SAE enrollment process, be initiated to the MME registration request of HSS;
At this moment, do not need among the MME user has been carried out authentication because user identity in SGSN authentication crossed, but MME need check whether allow this SGSN to insert.
In addition, as the TAI that derives is within this MME control range, and this MME will find suitable MME according to the TAI that derives, and the establishment PDP Context request message that will receive is forwarded to new MME, by this MME operation of execution in step 410 again.If MME can not derive TAI according to RAI, then enter step 413.
Step 411, MME is from HSS download user SAE data;
Step 412, HSS preserves the MME address, and returns the MME register response;
Step 413, after the MME registration HSS success, MME selects a UPE to be used for setting up user's face, UPE receive set up the user request in person ask after, distributing user IP address and to the tunnel information of SGSN;
It is multiple that MME selects the mode of UPE to have, and in the time of such as MME and UPE unification, just can select the UPE that unifies; MME also can select UPE, makes UPE as far as possible near eating dishes without rice or wine.
Step 414, UPE is established to user's face tunnel of IASA, and this step is optional;
Step 415, UPE sets up after user's face, return response to MME, MME distributes S-TMSI (SAE-Temporary Mobile Subscriber Identity), return the response of establishment PDP Context to SGSN, have: tunnel information and TAI that the IP address of S-TMSI, UPE distribution, UPE distribute in the parameter of creating band in the PDP Context response;
In the above-mentioned steps 410 to 415 with the SAE registration process in corresponding steps be identical.Just MME need not outside the subscription authentication, and in addition, the processing behind the registration failure is different, will be described below.
Step 416 after SGSN receives and creates the PDP Context response, is preserved tunnel information that UPE distributes, is set up the tunnel of SGSN to UPE, and returns PDP context activation to UE and respond, and carries S-TMSI, TAI and user's IP address in this message; UMTS module among the UE sends to the SAE module to these parameters again.
After UMTS registration and PDP context activation success, dual-mode terminal has been preserved following information: the UMTS module is preserved user's temporary mark P-TMSI, the route district RAI of registration and IP address etc.; The SAE module is preserved the user and is represented S-TMSI, the tracking area TAI of registration and IP address etc. temporarily.
In SAE and UMTS enrollment process difference be exactly the user after the SAE registration, default user plane bearer is also set up in the IP address that UPE can distributing user.And in UMTS, user plane bearer is just to set up in PDP context activation.In the present invention, when dual-mode terminal was initiated PDP context activation from UMTS, SGSN created the PDP Context request message by sending to MME, is triggered to the enrollment process of SAE.This time, MME and UPE were just jointly as GGSN for SGSN.And concerning MME/UPE, be equivalent to the user and be linked into MME/UPE from SGSN.
By above flow process, dual-mode terminal at first adheres in UMTS, and adheres in SAE by the pdp context activation of UMTS.Afterwards, through after a while, when SGSN discharged aerial user's face resource, SGSN need notify MME to enter idle condition, and then MME notice UPE user is in idle condition.
When dual-mode terminal detects when need be linked into SAE, whether the TA that preserves in the TA at the current place of SAE module check of terminal and the terminal is consistent, if inconsistent, be TA accurately then for what guarantee to preserve among the MME, need the enrollment process of initiation SAE.When the user when SAE initiates registration, E-RAN finds MME accurately according to S-TMSI.If consistent, illustrate that then the TA that preserves among the MME also is accurately, in this time, terminal need not to initiate renewal process from SAE, can reduce signaling like this.
In the foregoing description, if the user registers unsuccessful in SAE, such as the corresponding relation that can not find corresponding TAI according to RAI (this RA periphery does not have TA to cover), perhaps this user SAE CAMEL-Subscription-Information not among the HSS, this time is because MME and UPE are equivalent to GGSN, MME can select a UPE, by this UPE distributing user IP address with to the tunnel information of SGSN, be established to user's face tunnel (optional) of IASA, after MME receives the UPE response, in the establishment PDP Context response of returning to SGSN, push away the tunnel information that distributes with this UPE, thereby set up the tunnel of SGSN to UPE.MME need not to distribute S-TMSI, does not also need to bring dual-mode terminal with TAI in the PDP context activation response.In this case, not registration of SAE module in the dual-mode terminal, SAE only is equivalent to the GGSN among the UMTS, so the user can use the UMTS module to carry out business.
MME and UPE need not to know key information as GGSN when being established to user's face of SGSN.When the user initiates professional the time from SAE, MME can obtain authentication information the SAE from HSS, and carries out the SAE authentication, obtains key.
In sum, utilize the method among the present invention, can be implemented under the idle condition, when dual-mode terminal when UMTS forwards SAE to, can reduce the signaling of terminal to network.Simultaneously, owing in SGSN and MME, obtain and preserve separately user data from HLR/HSS respectively, like this to UMTS network and SAE systematic influence minimum.
