Abstract

The method includes following steps: setting up user's ID including private user id IMPI, and public user id IMPU carried by message of user data request (UDR) in advance; application server AS sends UDR message of carrying IMPI and IMPU to home registration user server HSS; based on IMPI and IMPU as well as coincidence relation between IMPI/IMPU and user registration state saved in advance, HSS obtains user registration state corresponding to IMPI and IMPU, and sends down user registration state to AS. The invention also discloses a system for requesting user registration state. The invention modifies current protocol. Thus, when IMPU is associated to multiple IMPIs, HSS can process UDR message of requesting user registration state.

Description

The method and system of user registration state are read in a kind of request
Technical field
The present invention relates to IP multimedia service sub-network (IMS) field, the method and system of user registration state are read in particularly a kind of request.
Background technology
In the IMS territory, in a subscription data (IMS Subscription), contain public subscriber identification (IMS Public User Identity, IMPU), (IMS Private UserIdentity is IMPI) with the international Integrated Service Digital Network number (MSISDN) of travelling carriage for private user identity.The relation that shown in Figure 1 is between the user ID of IMS territory, there are two IMPI:IMPI-1 and IMPI-2 among the IMS Subscription among the figure, and IMPI-1 is related with IMPU-1 and IMPU-2, IMPI-2 and IMPU-2 and IMPU-3 are related, and IMPU-1 and business datum (Service Profile) are-1 related, IMPU-2 and IMPU-3 and business datum-2 are related.As can be seen from Figure 1 have a plurality of IMPI in each IMSSubscription, also exist IMPI and an IMPU and an a plurality of IMPI related situation related with a plurality of IMPU simultaneously, promptly IMPI and IMPU are the relations of multi-to-multi.
User registration state (IMSUserState) and a pair of IMPI and the IMPU correspondence of in home signature user server (HSS), preserving, the i.e. corresponding relation of in store IMPI and IMPU and user registration state among the HSS.According to the TS 29328v6.4.0 agreement of 3rd Generation Partnership Project (3GPP), the User Status of preserving among the HSS comprises following four kinds: user registration state (REGISTERED), offline business state (REGISETERED_WITH_UNREG_SERVICE), off-line unregistered state (NOT_REGISTERED), authenticating identity state (AUTHENTICATION_PENDING).Wherein, REGISTERED represents that this user is by registration; REGISETERED_WITH_UNREG_SERVICE represents this user not by registration, but enjoys offline business; NOT_REGISTERED represents not registration of this user, and is in off-line state; AUTHENTICATION_PENDING represents that this user has initiated registration, is being verified identity, but is not also passing through.
AS can initiate user data requests (UDR) message request by the interface between AS and the HSS (Sh interface) and read user registration state.In the prior art, when AS when HSS initiates UDR message reading of data, according to the agreement regulation, the user ID of carrying in UDR message has only IMPU.The form of UDR message is as follows:
<User-Data-Request>::＝<Diameter?Header：306，REQ，PXY，16777217>
<Session-Id>
{Vendor-Specific-Application-Id}
{Auth-Session-State}
{Origin-Host}
{Origin-Realm}
[Destination-Host]
{Destination-Realm}
*[Supported-Features]
{User-Identity}
[Server-Name]
[Service-Indication]
{Data-Reference}
[Identity-Set]
*[Requested-Domain]
[Current-Location]
*[AVP]
*[Proxy-Info]
*[Route-Record]
When HSS asked the User Status data, the value of the parameter Data-Reference in the UDR message was IMSUserState, shows that the data type that this message request reads is the IMS user registration state at AS.User-Identity parameter in the UDR message is the user ID that is used for identifying user, and its structure is as follows:
User-Identity::＝<AVP?header：70010415>
[Public-Identity]
[MSISDN]
*[AVP]
From the structure of User-Identity as can be seen, in UDR message, do not carry IMPI, only carried IMPU and MSISDN.
After HSS receives UDR message, obtain corresponding user registration state according to the user ID in the UDR message and IMPI and IMPU with the corresponding relation of user registration state, and the user registration state that is obtained is handed down to AS by user data response (UDA) message.
But, because user registration state and a pair of IMPI and the IMPU correspondence of preserving among the HSS, and be the corresponding relation of multi-to-multi between IMPU and the IMPI, in UDR message, only carry IMPU, not necessarily can accurately navigate to the right user login state.When IMPU in the above-mentioned corresponding relation was only related with an IMPI, HSS issued the user registration state of this IMPI and IMPU correspondence; When IMPU was related with a plurality of IMPI, HSS can't correctly handle UDR message.
Summary of the invention
In view of this, the present invention proposes a kind of method and system of asking user registration state, can't handle the problem of UDR message in order to solution HSS when IMPU is related with a plurality of IMPI.
According to above-mentioned purpose, the invention provides a kind of method of asking user registration state, set in advance the user ID of carrying in the UDR message and comprise IMPI and IMPU, this method further may further comprise the steps:
A. application server AS sends the UDR message of carrying IMPI and IMPU to home registration client server HSS;
B.HSS obtains and described IMPI and the corresponding user registration state of IMPU with the corresponding relation of user registration state according to the IMPI and the IMPU of described IMPI and IMPU and preservation in advance, and by UDA message described user registration state is handed down to AS.
The present invention also provides a kind of system that asks user registration state, this system comprises AS and HSS, comprise the record cell that is used to preserve IMPI and IMPU and user registration state corresponding relation among the described HSS, comprise the request of data unit among the described AS, further comprise response unit among the described HSS, wherein, the request of data unit, be used to send the UDR message of carrying IMPI and IMPU, and receive the UDA message that HSS issues; Described record cell is further used for providing described corresponding relation to response unit; Described response unit, be connected with record cell, be used to receive described UDR message, and obtain and described IMPI and the corresponding user registration state of IMPU, and described user registration state is handed down to AS according to the corresponding relation that the described IMPI in the described UDR message and IMPU and described record cell provide.
From such scheme as can be seen, because the present invention has set in advance and carried IMPI and IMPU in UDR message, AS sends the UDR message of carrying IMPI and IMPU when the request user registration state, HSS then obtains corresponding user registration state according to IMPI and IMPU in the UDR message and existing IMPI and IMPU with the corresponding relation of user registration state, and this login state is handed down to AS by UDA message.The present invention makes when IMPU is related with a plurality of IMPI that by revising existing protocol HSS can correctly handle the UDR message of request user registration state.
