Description
Technical field
The present invention relates to moving communicating field, particularly relate to and between different network protocol, realize user's process registration in a kind of GSM architecture evolution.
Background technology
Along with continuing to bring out of new technology; 3GPP (3rd Generation Partnership Project; Third generation partner program) in future mobile communications neighborhood system architecture evolution, needs to consider lasting evolution and enhancing through from the wave point to the core network; In following 10 years, keeping own technological first-strike advantage, for operator and the ever-increasing demand of user provide satisfied support at moving communicating field.(System Architecture Evolution SAE), renames now that EPS (Evolved Packet System) starts just as under such background towards the evolution items of the packet domain core network of all-IP.The target of SAE is " formulate one have High Data Rate, low delays, packetization, support that multiple wireless access technology is the 3GPP system frame structure with portability of characteristic ".
The SAE network have support QoS (Quality of Service, service quality) end to end guarantee, comprehensively packetizing, support multi-access technology, increase support real time business, characteristics such as network layer flattening.The SAE network has further been realized separating of chain of command and user face data; MME (MobilityManagement Entity; Mobility Management Entity) newly-increased network element has functions such as the roaming of support, authentication, bearer management as the network function body of accepting the chain of command user data.S6a interface between MME and the HSS (HomeSubscriber Server, home subscriber server) referring to Fig. 1, provides download of user data, authorization data etc.
Normal structure adopts Diameter through the clear and definite S6a interface in back is discussed at present, but needs MME to support simultaneously to realize intercommunication with the HSS of different phase different editions.
The interface protocol that the HSS of different editions supports is also inequality; Wherein the HSS type is mainly used in HSS/HLR (Home Location Register, the attaching position register) function of distinguishing the different phase different editions; The protocol type that has shown its support has defined following several types:
-Rel-8 version independence HLR: only to Rel-8 version SGSN (Service GSN; Serving GPRS Support Node; Be the network element that core-network side is responsible for mobile management) and Rel-8 version GGSN (GatewayGSN; Gateway GPRS Support Node is the network element that core-network side is responsible for being linked into and sending out core net) provide based on the MAP Gr+ interface of (referring to be applied to the Gr+ interface protocol between the IWF);
-preceding Rel-8 version HSS/HLR: only Rel-8 version SGSN and preceding Rel-8 version GGSN provide the Gr interface based on MAP forward;
-Rel-8 version HSS: mainly referring to only provides the S6a interface based on Diameter to MME.
Like incumbent operator, Rel-8 version HSS/HLR or Rel-8 version independence HLR before the HSS type of its operation is generally, only seating surface is to the interface protocol of MAP.For the newly deployed SAE network of operator; The HSS of Rel-8 version can seating surface to the interface protocol of Diameter; If but the roaming agreement of signing between operator is not supported Diameter, as supporting MAP, MME can not realize the direct intercommunication with HSS under this kind scene.Normal structure has been introduced IWF (InterworkingFunction, IWF) and has been solved the mapping between Diameter and the MAP, so that realize MME and dissimilar HSS intercommunications, satisfies the demand of different operators.
IETF (Internet Engineering Task Force; The Internet engineering duty group) the regulation Diameter must be supported the Diameter basic agreement; That is to say the state machine of the client-server that the S6a interface protocol also must require in accordance with the user conversation of Diameter basic agreement definition.Diameter user conversation predetermined server can be the conversation maintaining state, can not be the conversation maintaining state also.Maintain sessions state no matter whether, the working mechanism of the working mechanism of Diameter user session state machine and MAP user session state machine is distinguished to some extent.MAP user session state machine allows peers include both after session is set up; Can initiate repeatedly interactive request each other; Be that this end points is when receiving the conversation request of peer end point; Can during session is set up, send conversation request to peer end point once more, when receiving the conversational response of peer end point, return the conversational response of peer end point again.Diameter user session state machine does not allow client computer to open the back in session and receives the request from server, response message that can only processing server.
Seeing that Diameter and MAP cause user's register flow path can not realize shining upon fully in the difference of user session state machine.The session status machine that provides by means of MAP, when the user in the visit territory during network registry, its home domain network can be realized and visit the ability information of territory network and consulted.Give one example; When user attaching territory network receives user's login request message; To visit territory network egress access customer data; If the insertion user data is failed then return data inserts failure, user attaching territory network forbids that the user registers, and returns the response message of registration failure to the visit territory network of user's roaming.If the use Diameter, user attaching territory network HSS can only return registration reply message when receiving user's login request message, when the registration reply message that returns success, thinks user registration success.
This scene appears at user attaching territory network HSS and supports Diameter, and promptly the HSS type is Rel-8 version HSS.If support the SGSN desire of MAP to realize and the intercommunication of HSS, just must carry out the conversion between the procotol, referring to Fig. 2 through IWF.If signed the roaming agreement based on signalling system No.7 between operator, then supporting need change through at least two IWF between MME and the Rel-8 version HSS of Diameter mutually, and the interface protocol based on MAP is provided between the IWF, uses the Gr+ interface, referring to Fig. 3.
In sum, the problem of prior art existence is:
1, SGSN sends user's registration message through IWF to the HSS that only supports Diameter, if user attaching territory network HSS can't be in time notified in the processing failure after IWF received registration reply message, causes the user inconsistent at the log-on message of SGSN and HSS;
2, MME and HSS support Diameter simultaneously; And receive and the registration message of process user based on Diameter; But signed the roaming agreement based on signalling system No.7 between operator, only allowed to use the MAP interacting message, MME needs to realize and the HSS intercommunication through IWF indirectly; If user attaching territory network HSS can't be in time notified in the processing failure after IWF received registration reply message, also can cause the user inconsistent at the log-on message of MME and HSS.
Summary of the invention
The technical problem that the present invention will solve proposes to realize between a kind of different network protocol user's process registration exactly; When overcoming in the prior art user network be through the Interworking gateway registration abnormity in the visit territory; Home domain network and the problem of visiting territory network registry information inconsistency, assurance home domain network can in time be deleted user's registration information.
In order to solve the problems of the technologies described above, the present invention provides and realizes user's process registration between a kind of different network protocol, comprises the steps:
(1) user initiates the network attachment request at visit territory network, to the request message of the home subscriber server HSS of user attaching territory network belonging registration through at least one IWF IWF and carry out the said HSS of procotol conversion back arrival;
(2) said HSS receives the said back request message of procotol conversion that carries out, and handles successfully and then returns registration reply message to IWF, preserves this user's registration information simultaneously;
(3) IWF receives the registration reply message of said HSS, if handle unusually, the user who then sends the network protocol defining of supporting based on this HSS to said HSS deactivates request message, this user's of request HSS deletion registered user's registration information.
Further, the visit territory network in the said step (1) is the Serving GPRS Support Node SGSN that operator disposes, and supports MAP; The Mobility Management Entity MME that perhaps disposes for operator supports Diameter.
Further, the procotol in the said step (1) converts Diameter into and converts MAP to; Perhaps MAP converts Diameter to.
Further; The procotol that said HSS supports is a Diameter; In the said step (2), the request message that carries out after procotol is changed that HSS receives is that Diameter-upgrades location request message, and the registration reply message of said HSS is that Diameter-upgrades the position response message.
Further, the IWF of said step (3) handles and refers to that unusually IWF inserts the user data failure to user's attach to network, comprises when the SGSN of IWF in user's attach to network inserts user data SGSN verified users data failure; And the MME in user's attach to network and user attaching network HSS be when two IWF intercommunications, near the IWF of home domain network when the IWF near user's attach to network inserts user data, near the IWF verified users data failure of user's attach to network.
Further, the user deactivates request message and comprises ID and the registered network identity of user in the said step (3).
Further, said ID is user's a IMSI International Mobile Subscriber Identity.
Further, if the visit territory network in the said step (1) is SGSN, the registered network identity of user that the user deactivates in the request message in the then said step (3) is the address identification message of SGSN;
If the visit territory network in the said step (1) is MME, the registered network identity of user that the user deactivates in the request message in the then said step (3) is the address identification message of MME.
Further, after said step (3) was carried out, HSS received said user and deactivates request message, then verifies the legitimacy of message, if checking is through this user's of deletion user's registration information; Otherwise, do not delete this user's user's registration information.
Further, whether the legitimacy of said checking message is consistent for checking user registered network location information and said user deactivate the registered network identification information of the user who carries in the request message, as if unanimity, then verify successfully, otherwise, authentication failed.
The present invention is directed between different network protocol and realize the scene that the user registers through Interworking gateway; Proposed IWF and received the registration reply message of user attaching territory network and handle when unusual and send the method that the user deactivates the log-on message of request message deletion user attaching territory network, guaranteed the correctness of user attaching territory network registry information to user attaching territory network.
