Abstract
In IMS network, after receiving SAR message sent from S-CSCF, HSS obtains type of operation from parameter of Server-Assignment-Type carried by SAR message. Base on own stored current registration state of the user, HSS determines whether the type of operation is legal; if yes, carrying out service treatment based on type of operation; otherwise, refusing the requested operation. That is to say it is needed for HSS to check up whether there is conflict between the stored current registration state of the user and type of operation requested before carrying out service treatment. The invention discloses treatment mechanism of checking conflict in order to guarantee consistency and categoricalness for treating log in/log out user among entities of IMS network. The invention improves flow of user's logging in/logging out in IMS network.
Description
Technical field
The present invention relates to IP multimedia subsystem, IMS (IMS) field, be meant a kind of especially user registration/cancel request (SAR, Server-Assignment-Request) method handled of message based on Internet protocol (IP).
Background technology
When the user registers in the IMS network, service call session control function entity (S-CSCF) can send SAR message to HSS by the interface (Cx interface) between call conversation control function entity (CSCF) and the home signature user server (HSS), carry server assignment type (Server-Assignment-Type) parameter in this SAR message, the Server-Assignment-Type parameter has 12 kinds of values, every kind of action type that value is corresponding different, each action type has corresponding implication, and particular content is referring to table one; After HSS receives SAR message, at first obtain action type, carry out corresponding operating then according to the value of the Server-Assignment-Type parameter of carrying in the SAR message.
| Action type | Implication |
| NO_ASSIGNMENT | Fetch data |
| REGISTRATION | Registration |
| RE_REGISTRATION | Heavily registration |
| UNREGISTERED_USER | Take family unregistered state business |
| TIMEOUT_DEREGISTRATION | Overtime cancellation |
| USER_DEREGISTRATION | User log off |
| TIMEOUT_DEREGISTRATION_STORE_SER VER_NAME | Nullify overtime and the preservation server address |
| USER_DEREGISTRATION_STORE_SERVER NAME | User log off is also preserved server address |
| ADMINISTRATIVE_DEREGISTRATION | The operator nullifies |
| AUTHENTICATION_FAILURE | Failed authentication |
| AUTHENTICATION_TIMEOUT | Authentication is overtime |
| DEREGISTRATION_TOO_MUCH DATA | Overabundance of data is nullified |
The value of table one Server-Assignment-Type parameter and implication corresponding relation
Store user's current login state among the HSS.User's login state comprises three kinds: unregistered (Not Registered), registration (Registered) and called unregistered (Unregistered), and wherein, Not Registered is meant that the user is unregistered and is not assigned with service S-CSCF; Registered is meant that the user has registered and be assigned with service S-CSCF; The unregistered service S-CSCF that has been assigned with provides the unregistered state business for it but Unregistered is meant the user.According to the regulation of agreement 3GPPTS29.228 and 3GPP TS29.229, when S-CSCF changes in User Status, can be by SAR message request notice HSS, correspondingly, HSS need preserve its current login state in the IMS network for the user.
By table one as seen, HSS receives SAR message, obtain action type according to the value of Server-Assignment-Type parameter after, as follows according to the corresponding operating that action type is carried out:
When action type is NO_ASSIGNMENT, HSS by user registration/cancel response (SAA, Server-Assignment-Answer) message is returned the data that read to S-CSCF, does not change this user's current login state;
When action type was REGISTRATION, HSS changed to Registered with user's current login state, and returns SAA message to S-CSCF;
When action type was RE_REGISTRATION, HSS heavily registered the user, and the current login state of recording user is Registered, and returned SAA message to S-CSCF;
When action type was UNREGISTERED_USER, HSS changed user's current login state into Unregistered, by SAA message to S-CSCF return ask the business datum that reads;
When action type was TIMEOUT_DEREGISTRATION, USER_DEREGISTRATION or ADMINISTRATIVE_DEREGISTRATION, HSS changed to Not Registered with user's current login state, and returns SAA message to S-CSCF;
When action type is TIMEOUT_DEREGISTRATION_STORE_SERVER_NAME or USER_DEREGISTRATION_STORE_SERVER_NAME, HSS changes to Unregistered with user's current login state, and in HSS, store S-CSCF name (ServerName), and return SAA message to S-CSCF;
When action type is AUTHENTICATION_FAILURE or AUTHENTICATION_TIMEOUT, HSS will remove user's the unsettled sign of authentication (Pending Flag), user's current login state is changed to Not Registered, and return SAA message to S-CSCF;
When action type was DEREGISTRATION_TOO_MUCH_DATA, HSS changed to Not Registered with user's current login state, and returns SAA message to S-CSCF.
According to above description as seen, in the value of Server-Assignment-Type parameter not simultaneously, the action type difference that it is corresponding, the implication that each action type is represented is also inequality, be that SAR message institute requested operation type is also inequality, but, there is incorrect situation in the action type of obtaining according to the value of the Server-Assignment-Type parameter of carrying in the SAR message, for example, the Server-Assignment-Type parameter value that carries in the SAR message of HSS according to the S-CSCF transmission, the action type that gets access to is UNREGISTERED_USER, if the current login state of the user who stores among the HSS is Registered, for the user who has registered, unregistered state business to HSS request user obviously is inappropriate again, like this, the incorrect HSS that will cause of Server-Assignment-Type parameter value carries out wrong operation, make HSS correctly to handle, can't guarantee between the IMS network entity user registration/cancel uniformity of treatment and completeness to SAR message.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method that the user registration/cancel request message is handled, make HSS correctly to handle, thereby guarantee between the IMS network entity user registration/cancel uniformity of treatment and completeness to SAR message.
