Description

The acquisition methods of tunnel identification information, sending method, equipment and system
Technical field
The present invention relates to mobile communication technology, particularly relate to a kind of acquisition methods, sending method, equipment and system of tunnel identification information.
Background technology
Along with development of internet technology, the intercommunication of third generation partner program (3GPP, Third GenerationPartnership Project) evolvement network and non-3GPP network is the crucial topic that current standardization body is discussed.Wherein, That of greatest concern is the High Rate Packet Data (eHRPD of 3GPP evolvement network and evolution; Evolved High Rate Packet Data) intercommunication of network in the framework of 3GPP network and eHRPD network interworking, has increased by two interfaces; First interface is the S101 interface, and second interface is the S103 interface.The S101 interface is the interface between Mobility Management Entity (MME, Mobility Management Entity) and the evolution Access Network (eAN, evolved Access Network); Its essence is a tunnel; Be the S101 tunnel, the S101 interface is made up of the S101 tunnel, each a S101 tunnel and a unique terminal binding; Be used for transmitting the signaling message between terminal and the objective network, accessory terminal carries out pre-registration or switches to objective network from source network at objective network; The S103 interface is gateway (S-GW; Serving Gateway) and high-rate packet data services gateway (HSGW; High Rate PacketData-Serving Gateway) interface between; The data that are used to transmit the delay of 3GPP evolvement network send to the terminal through the eHRPD network then to the eHRPD network.
The dual-mode terminal of supposing Long Term Evolution (LTE, Long Term Evolution)/eHRPD is the dual-mode terminal of single-emission and double-receiving.In this case, when the terminal on a network transceive data time, it can not carry out the work of registration, authentication or session negotiation simultaneously on the another one network.When the result causes terminal across accesses technical to switch, must register earlier, work such as authentication or session negotiation.These processes need several seconds usually, cause transfer of data to interrupt, and have greatly influenced the quality of service of real time business in handoff procedure.In order to reduce the terminal that real time business switches; The notion of " pre-registration " has been proposed in the present technology; Promptly when terminal still also at source network the time, the terminal is transceive data on one side, on one side through source network and work such as S101 interface and objective network execution registration, authentication or session negotiation.Really carry out can beginning immediately when inter-network is switched at the terminal in the objective network transceive data, thus the break period that can at utmost reduce the inter-network service switchover.
After pre-registration was carried out at the terminal, before the terminal really switched to objective network, terminal and objective network can carry out Signalling exchange through source network and S101 interface as required at any time.For example, when service quality (QoS, Quality of Service) configuration information changed, terminal and objective network be consulting session information again.Because each S101 tunnel all uses a S101 session id (S101Session Identity) as sign.Owing to international mobile contracted user's sign (IMSI, International Mobile SubscriberIdentity) overall situation is unique, the IMSI that present standardization body tends to adopt the terminal is as the S101 session id.Like this, when network entity changes, need not change the S101 session id, the work that the S101 session id distributes and safeguards in the time of can reducing the network entity switching.
In current eHRPD standard; If the terminal in eHRPD network transceive data, subsequently, need switch to LTE network transceive data; When the terminal from the eHRPD network to the process that the LTE network switches, though can pass through the IMSI information at access authentication (through the A12 interface) acquisition terminal.But; Whether the target criteria tissue supports access authentication still not have final conclusion for the eHRPD network, if the eHRPD network is not supported access authentication, and eAN can't obtain the IMSI at terminal; Will cause the confusion of the Tunnel Identifier on the S101 interface, thereby cause both sides' handoff failure.

Explain with concrete application implementation example below, need explain that the terminal in the application implementation example is example with the dual-mode terminal, but is not limited to this.
Seeing also Fig. 2, be the present invention's first application implementation example, in this embodiment, need be example to the flow process that authentication is carried out at the terminal with MME.
In this embodiment, switch to the example explanation with the eHRPD network to the LTE network.Suppose to insert the eHRPD network behind the double-module terminal start-up of single-emission and double-receiving, and in eHRPD network transceive data.Subsequently, dual-mode terminal (perhaps network side) decision switches to LTE network transceive data.Its concrete implementation procedure is as shown in Figure 2:
Step 201: dual-mode terminal (among the figure shown in the UE) is the eAN registration in the eHRPD network, also might set up a data session through the eHRPD network insertion.Promptly start eHRPD radio frequency (eHRPDRadio On), its concrete implementation procedure is a known technology to those skilled in the art, repeats no more at this.
Step 202: in conversation procedure, decision switches to LTE network (Decisionto handover LTE) from the eHRPD network, promptly to the LTE message at LTE Network Transmission terminal, can initiated to switch by network side, also can initiated to switch by dual-mode terminal.
Step 203: based on the decision of switching, dual-mode terminal is initiated attachment flow (present embodiment initiates to switch to example with dual-mode terminal), and dual-mode terminal sends an attach request (Attach Request) message through the air interface of eHRPD to eAN.Said Attach Request message is encapsulated among the idle message X of eHRPD.If successfully be attached to certain MME before the said dual-mode terminal, MME has set up the context of said dual-mode terminal and has distributed temporary mark for said dual-mode terminal, and Attach Request message will comprise said temporary mark so.Otherwise the IMSI that has said terminal in the Attach Request message.
Step 204: when eAN receives the message X that dual-mode terminal sends, eAN selects a MME, and eAN is to MME transmission S101 tunnel message (being direct message transfer, S101 DirectTransfer) then.Said direct message transfer comprises the S101 session id, T-ID and Attach Request message.EAN S101 session id is set to null value, for example uses complete zero perhaps other particular value to represent null value.After MME receives that the S101 session id is set to empty S101 message, it is interpreted as the S101 session id in the said tunnel of eAN request feedback.EAN T-ID is set to terminal Unicast Access Termination Identifier (UATI, Unicast Access Terminal Identifier).Attach Request is the LTE signaling message that dual-mode terminal is issued MME, as the load of S101 Direct Transfer.
A kind of in addition situation is that said direct message transfer comprises the field of request feedback S101 session id, T-ID and Attach Request message.Receive the S101 message of the field that has request feedback S101 session id as MME after, will feed back the S101 session id.Also have a kind of situation to be exactly, include only T-ID and Attach Request message, receive the S101 message of having only T-ID as MME after, will feed back the S101 session id.Present embodiment is the example explanation with first kind of situation, but is not defined as first kind of situation.
In addition, except can using the T-ID of UATI as the S101 tunnel, eAN can also use Electronic Serial Number ESN as T-ID.Perhaps interim that distribute and AT of eAN one to one sequence number as T-ID.Present embodiment is the example explanation with UATI, but is not defined as UATI.
Step 205a:MME obtains the IMSI of said dual-mode terminal.If comprise the IMSI of said dual-mode terminal in the Attach Request message then directly carry out step 205b.If what comprise among the Attach Request is that original MME is the temporary mark that said dual-mode terminal distributes, MME sends the IMSI of the said dual-mode terminal of temporary mark request of said dual-mode terminal to original MME.MME originally sends to MME with the IMSI of said dual-mode terminal.(concrete implementation procedure sees Fig. 2 for details)
Step 205b:MME asks the information and the CAMEL-Subscription-Information of the authentication of said dual-mode terminal to the IMSI of the said dual-mode terminal of HSS (local assigned user server) transmission.HSS sends the CAMEL-Subscription-Information at said terminal and the information of authentication to MME.
Step 205c:MME sends S101 tunnel message (is example with S101 Direct Transfer message) to eAN, comprises S101 Session ID in the said message, T-ID, and MME issues the authentication request message of the LTE of dual-mode terminal.MME S101 Session ID is set to the IMSI of dual-mode terminal, the T-ID of the S101 Direct Transfer message that receives in the T-ID copy step 204, i.e. UATI.
EAN obtains the S101 Session ID in said S101 tunnel from said S101 Direct Transfer message after receiving S101 Direct Transfer message, in the present embodiment, i.e. and the IMSI of dual-mode terminal.EAN switches to S 101 session identifications with the temporary mark in the S101 tunnel of said dual-mode terminal.Promptly begin from step 205d, eAN is that the S101 tunnel message that said dual-mode terminal sends only comprises the S101 session identification, does not comprise temporary mark T-ID.In the present embodiment, the S101 session identification is set to the IMSI of said dual-mode terminal.
Step 205d:eAN is after the authentication response message that receives the UE transmission; Send S101 tunnel message (is example with S101Direct Transfer message) to MME, said S101 tunnel message comprises: the S101 Session ID and the authentication response message (Authentication Response) that MME is issued at said terminal that are set to the IMSI of dual-mode terminal.
Need to prove that the message of transmitting among step 204, step 205c, the step 205d all is the message through the tunnel, said tunnel can be S101 tunnel etc.
After step 206:MME obtains the information of said dual-mode terminal, trigger the foundation of the Data-carrying between gateway (S-GW, Serving Gateway) and the grouped data network gateway (P-GW, Packet Data Network Gateway).And might carry out the flow process of a Location Update.
Step 207: receive after the order of setting up the default data carrying of S-GW response, MME sends a direct message transfer of S101 and gives eAN.The direct message transfer of said S101 comprises the Attach Accept message that S101 session identification and MME issue said dual-mode terminal.In the present embodiment, the said S101 session identification IMSI that is said dual-mode terminal.
Step 208:eAN is encapsulated in Attach Accept message among the eHRPD idle message X and issues dual-mode terminal.
Step 209: dual-mode terminal adheres to completion (Attach Complete) message with one and is encapsulated among the eHRPD idle message X and issues eAN.
Step 210:eAN sends a direct message transfer of S101 and gives MME.What the direct message transfer of said S101 comprised that S101 session identification and said dual-mode terminal issue MME adheres to completion message.In the present embodiment, the said S101 session identification IMSI that is said dual-mode terminal.
Need to prove that the message of transmission all is the message through the tunnel in step 207, the step 210, said tunnel can be S101 tunnel etc.
Step 211: after accomplishing the E-UTRAN attachment flow, dual-mode terminal switches to E-UTRAN, promptly starts the LTE radio frequency.
In case step 212. dual-mode terminal is connected to eNB, dual-mode terminal will create and activate radio bearer and S1 carries, and is connected to EPC network (Evolved Packet Core, evolution block core net network).
Step 213: be activated in case E-UTRAN carries, MME sends a S101 handoff completion message and gives eAN (being S101 HO Complete).
After step 214:eAN receives this message, can discharge the resource of eHRPD network.
Need to prove; The embodiment of the invention also can support S101 Session ID to use other the sign of non-IMSI; Other this sign includes but not limited to this, international travelling carriage identification code (IMEI, International Mobile Equipment Identity); Or MME is the sequence number of terminal distribution, as long as this sign is corresponding one by one with the terminal.
The foregoing description; Mainly described the flow process that to carry out authentication with MME to dual-mode terminal, and, obviously also can use the embodiment of the invention for the situation that does not need MME to terminal execution authentication; MME can be in step 207; The S101 session identification of the direct message transfer of S101 is set to the IMSI of dual-mode terminal, and eAN is after receiving the direct message transfer of said S101, and eAN switches to the S101 session identification with the temporary mark in the S101 tunnel of said dual-mode terminal.Promptly from step 210 beginning, eAN is that the S101 tunnel message that said dual-mode terminal sends only comprises the S101 session identification, does not comprise temporary mark T-ID.
Also see also Fig. 3, be the present invention's second application implementation example.This second application implementation example is basic identical with the flow chart of the Attach Request message band temporary mark of first application implementation example, and its unique difference is that MME can't be known the identity of this dual-mode terminal from original MME.Therefore MME must send IdentityRequest and gives dual-mode terminal to obtain the IMSI information of this dual-mode terminal.Concrete implementation procedure is:
Said second application implementation example comprises with first application implementation example something in common:
Step 201, step 202, step 203, step 204 corresponding in step 301, step 302, step 303, step 304 and the first application implementation example are identical, specifically see for details above-mentionedly, repeat no more at this;
Step 305a is identical with step 205a, and still for a certain reason (for example the time of dual-mode terminal attachment removal surpasses certain restriction), MME has originally deleted the IMSI information of said dual-mode terminal.Therefore MME can't obtain the IMSI of said dual-mode terminal from original MME.
Step 306a sees the step 205b in the first application implementation example for details;
Step 306b sees the step 205c in the first application implementation example for details;
Step 306c sees the step 205d in the first application implementation example for details;
Step 307 sees the step 206 in the first application implementation example for details;
Step 308 sees the step 207 in the first application implementation example for details;
Step 309 sees the step 208 in the first application implementation example for details;
Step 310 sees the step 210 in the first application implementation example for details;

Step 313 sees the step 212 in the first application implementation example for details;
Step 314 sees the step 213 in the first application implementation example for details;
Step 315 sees the step 214 in the first application implementation example for details;
Said second application implementation example comprises with first application implementation example difference: if MME can't obtain the information of S101 Session ID at the beginning; Be the IMSI of dual-mode terminal in the present embodiment; Then MME and eAN can use the S101 temporary mark with difference S101 tunnel always; Up to the information of MME acquisition S101 SessionID, MME reinforms the information of the S101 Session ID in the said S101 of eAN tunnel.After obtaining the S101 session identification of said dual-mode terminal, eAN switches to the S101 session identification with the temporary mark in said S101 tunnel.
The main difference part is step 305b and the 305c among Fig. 3.Be specially:
Step 305b:MME sends the direct message transfer of S101 to eAN, comprises in the said message: the S101 session identification, and T-ID, and MME issues the identification request message of dual-mode terminal.In the present embodiment, MME is set to null value with the S101 session identification, and it is that UATI is an example that T-ID is set to, but is not limited to this.
EAN is encapsulated in said identification request message among the HRPD idle message X and issues dual-mode terminal after receiving the direct message transfer of said S101;
Step 305c: dual-mode terminal is encapsulated in identification response message among the HRPD idle message X and issues eAN.The IMSI that comprises said dual-mode terminal in the identification response message.EAN sends the direct message transfer of S101 to MME, comprises in the said message: S101 Session ID, and T-ID, and dual-mode terminal is issued the identification response message of MME.In the present embodiment, eAN is set to null value with S101 Session ID, and it is that UATI is an example that T-ID is set to.
Need to prove that MME also can only comprise the identification request message that T-ID and MME issue dual-mode terminal in the direct message transfer of said S101, do not comprise the S101 session identification.Accordingly, eAN only comprises the identification response message that T-ID and dual-mode terminal are issued MME in the direct message transfer of said S101, do not comprise the S101 session identification.
