Description
Technical field
The present invention relates to internet protocol multimedia subsystem (IMS) technology, refer to a kind ofly between the IMS network entity especially, transmit the method for internet protocol multimedia subsystem signatory mark (SUBID, IMS SubscriptionIdentity).
Background technology
In the IMS network, user's subscription data is stored in the home subscriber server (HSS).HSS externally provides Ying Yetingjiekou, is used for user data and safeguards, such as inquiring about, increase newly, revise, delete user contracting data etc., by Ying Yetingjiekou user bound sign and this user ID corresponding user data.Simultaneously HSS supports Cx interface, be used for and inquiry CSCF (I-CSCF) and service call conversation control function (S-CSCF) between alternately; Support Sh interface, be used for application server (AS) between alternately.By Cx interface or SH interface, can obtain user data from HSS, such as: when the user carries out network registration, the message of registering is delivered to HSS, and obtains user contracting data, to carry out subsequent business operation from HSS.
In order to obtain active user's user data, need in mutual, carry user ID.In the IMS related protocol, the user ID of transmitting between network entity has IMS private user identity (IMPI, IMSPrivate User Identity), IMS public subscriber identification (IMPU, IMS Public User Identity), mobile station ISDN number (MSISDN) and IMSI International Mobile Subscriber Identity (IMSI) etc., these user ID all are saved among the HSS by Ying Yetingjiekou is signatory, when the user need carry out the related service operation, obtain subscription data to HSS by user ID.
Among the IMS user ID concern more complicated, as shown in Figure 1, Fig. 1 is that prior art IMS user ID concerns schematic diagram, from the logic inclusion relation, there is following relation in the IMS user ID:
Can comprise a plurality of IMPI among the SUBID; An IMPI can only belong to a SUBID; Can comprise a plurality of IMPU among the IMPI; An IMPU can belong to a plurality of IMPI.That is to say that SUBID and IMPI are the relations of one-to-many, IMPI and IMPU are the relations of multi-to-multi.
At present, the HSS mode that issues user data has following several:
1) I-CSCF obtains user contracting data by Cx interface from HSS, such as user's capability set (Capabilities) requirement or the S-CSCF of current service etc.I-CSCF carries user ID such as IMPI or IMPU in user registration state query requests (UAR), to HSS request user contracting data; HSS issues user contracting data by user-authorization-answer (UAA) message, such as the title (S-CSCF Name) of the S-CSCF of current service or satisfy the S-CSCFCapabilities of customer requirements.Wherein, the S-CSCF Name that issues of HSS and S-CSCF Capabilities satisfy SUBID desired S-CSCF Name or the S-CSCF Capabilities of active user under identifying.
2) I-CSCF obtains user contracting data from HSS, such as user's the Capability Requirement or the S-CSCF of current service etc. by Cx interface.I-CSCF carries user ID such as IMPU in customer location query requests (LIR), to HSS request user contracting data; HSS issues user contracting data by location-info-answer (LIA) message, such as the S-CSCF Name of current service or satisfy the S-CSCF Capabilities of customer requirements.Wherein, the S-CSCF Name that issues of HSS and S-CSCF Capabilities satisfy SUBID desired S-CSCF Name or the S-CSCFCapabilities of active user under identifying.
3) S-CSCF obtains user contracting data and charging address by Cx interface from HSS.S-CSCF carries user ID such as IMPI/IMPU in user registration/cancel request (SAR) message, to HSS request user contracting data and charging address; The user data that HSS issues by user registration/cancel response (SAA) message is relevant with this IMPI/IMPU and implicitly registered set thereof, and specific implementation can repeat no more here with reference to the regulation among the 3GPPTS29.228v6.5.0.Description (User Profile) file and the charging address information (Charging information) of user profile.
4) AS is by Sh interface, the subscription data or the charging address that obtain the user from HSS.AS carries user ID such as IMPU in user data requests (UDR) message, to HSS request user contracting data or charging address; HSS is User Profile or the Charging Information relevant with this IMPU by the user data that user data response (UDA) message issues.
In addition, HSS can initiatively issue user contracting data, and such as after user contracting data or the renewal of charging address, HSS upgrades the user data of preserving among the S-CSCF synchronously by the PPR/PPA message of Cx interface.Wherein, carry user ID such as IMPI in the PPR message.
Form and the application scenarios of IMPI and IMPU have clearly been stipulated in the existing protocol.The form of regulation IMPI is NAI among third generation partner program (3GPP) TS23.003, specifically can be with reference to IETF RFC2486 associated description; The form of regulation IMPU is SIP URL among the 3GPP TS29.229v6.3.0, can perhaps be TEL URL with reference to IETF RFC 3261 and IETF RFC 2396 associated description specifically, specifically can be with reference to IETF RFC 2806 associated description.Above-mentioned HSS issues in the user contracting data, and IMPI and IMPU can be with reference to 3GPP TS29.228v6.5.0 relevant regulations at the application scenarios of Cx interface, and IMPU can be with reference to 3GPP TS29.328v6.4.0 relevant regulations at the application scenarios of Sh interface.
But, do not provide form and the application scenarios of SUBID in the existing protocol, do not provide the method that SUBID transmits between the IMS network entity yet.Like this, newly-increased if desired IMPI/IMPU, and newly-increased IMPI/IMPU belongs to existing SUBID, can't identify newly-increased IMPI/IMPU and belong to existing SUBID this moment.
Equally, entities such as S-CSCF/AS can't obtain user's SUBID information by the user data that existing Cx/Sh interface issues, thereby can't obtain the relation between SUBID and IMPI/IMPU.And when a plurality of IMPI belonged to same SUBID, utilization merchant and end user wished to obtain this SUBID information, thereby realized the management to the user ID relation.
