Abstract
The present invention relates to a method for a home call conversation control server to obtain an initial request filter condition. All iFC data is configured on an HSS; when an S-CSCF is initialized, the HSS notifies the corresponding ID to an S-CSCFiFC from an HSSiFC data, and ID of each iFC; or when a user sends out a request, the HSS transmits the ID of the iFC to the S-CSCF, the S-CSCF judges whether the relative data corresponding to the iFC ID of the user is downloaded, and if the relative data is not downloaded, complete iFC data is requested from the HSS; when the S-CSCF obtains theiFC data from the HSS, the HSS only informs the S-CSCF of the ID of the iFC during the registration process of uses. Because the S-CSCF does not require configuring the iFC data, the present invention effectively solves the problem that the original proposal causes each network element management to be complicated, and simultaneously all the advantages brought by the originally shared IFC are basically maintained.
Description
Technical field
The present invention relates to communication field, particularly home calling session control server (S-CSCF) obtains the method for initial request filtercondition (iFC) data in the user contracting data in next generation network IMS (IP Multimedia System) network.
Background technology
Along with the development of mechanics of communication, (CRBT, multimedia message, POC etc.) appear in increasing individual business thereupon.In order to satisfy the development of colourful IP multimedia service, communication network IPization.3GPP has at first proposed the notion of IMS (IP Multimedia System) in the 3rd generation mobile communication network, along with further investigation to IMS, the IMS network configuration walked out gradually only serve the 3rd generation mobile communication network restriction, become the fusion architecture of fixed network next generation network (NGN) and mobile NGN.
The IMS network has been inherited the pattern of traditional mobile communication network, and the user can move and roam, and this realizes by the IMS user registration course.
The IMS network mainly is made up of CSCF server (CSCF), media resource function server (MRF), home subscribed services device (HSS), intercommunication node (as: media gateway controlling server MGCF, out gateway Control Server BGCF) and application server (AS).CSCF finishes user's registration and session control triggers function, is divided into Proxy Call Session Control Function server (P-CSCF), intercommunication CSCF server (I-CSCF), home calling conversation control function server (S-CSCF) again.MRF control medium face is finished such as playback the conversion of user's face code, functions such as conferencing resource control.HSS is the same notion with HLR in the mobile communication, and it has stored user's all CAMEL-Subscription-Information and user position information.The intercommunication node is finished the IMS network user and other networks (PSTN, 2G, ETC) user's intercommunication.AS is a business processing network element in the IMS network, and the S-CSCF of IMS network is triggered to corresponding AS by the iFC that the user contracts with session, finishes correspondent service logic by AS.
IFC is a kind of filtering rule condition, is the XML form, belongs to the some of user contracting data, is stored among the HSS, has realized separating of business and session control by iFC.IFC has defined and has received the SIP initial request message will be triggered to calling the rule that application server is carried out the corresponding service logic according to which condition criterion, for example can define among the iFC when receiving INVITE, and when the FROM field of message comprises " joe ", call out and be triggered to certain application server.
IMS uses iFC to finish professional and control separation steps following (comprise and obtain iFC and use two stages of iFC)
One. the user obtains iFC in the subscription data by registration
Fig. 1 is the existing user's initial registration flow process of IMS:
Step 101: the user is initiated to the initial registration REGISTER of IMS network;
Step 102:P-CSCF transmits the home network I-CSCF of REGISTER to the user;
Step 103:I-CSCF is according to the inquiry of the user ID in REGISTER message HSS;
Step 104:HSS returns the S-CSCF of distributing user registration, or selects the capability set of S-CSCF;
Step 105:I-CSCF sends to S-CSCF according to the S-CSCF of HSS distribution or the S-CSCF that selects according to capability set with user's registration information;
Step 106:S-CSCF carries out authentication to the user;
Step 107: after authentication was passed through, S-CSCF returned 200 responses by CX interface download user subscription data (wherein comprising iFC) and preservation to the user, finishes registration.
Two. the user uses iFC to trigger operation flow for example:
Fig. 2 is IMS user's calling service trigger flow process
Step 201: user A is initiated to the session of user B, and the user A caller ID display restriction supplementary service of having contracted carries the Privacy:id parameter in the INVITE of initiation;
The iFC of step 202:S-CSCF inquiring user A has the Privacy:id of comprising parameter if iFC indicates in the INVITE request, is triggered to AS and carries out Business Processing;
The caller ID display restriction supplementary service of step 203:AS process user A, and continue calling party B.
Step 204:S-CSCF is to user B routing call request
We can see from above background is described
1, iFC is owing to adopt the coded format of XML, and its message size is bigger, and the step 107 of the each registration of user all will be downloaded by the cx interface when obtaining iFC in the phase I, can influence network performance;
2, the identical situation of the iFC that exists a kind of business concerning a large number of users, may use.
In order to address the above problem, the implementation of a kind of shared iFC has been proposed in the 3gpp agreement, be exactly that S-CSCF and HSS dispose the iFC data simultaneously, and give each iFC configuration identical ID, during the step 107 download user iFC of user registration, HSS only returns the ID of iFC, and S-CSCF determines the iFC of ID correspondence according to configuration.The scheme of agreement improves network performance, makes a large number of users can share same iFC in S-CSCF.But there is the complicated problem of each NE management of network that makes in this solution:
1, originally do not adopt the S-CSCF that shares the iFC technology need not dispose the iFC data, but need be configured now, and must guarantee that the data of itself and HSS are on all four;
If 2 share iFC wholesale revision takes place, then all S-CSCF need to make amendment, and comprise the data on the HSS, and the workload of its configuration change is bigger.
Summary of the invention
The technical problem to be solved in the present invention is, at the problem that prior art exists, proposes the method that a kind of S-CSCF after shared iFC technology is improved obtains iFC.
Technical scheme of the present invention may further comprise the steps:
Step 1: initial request filtercondition (iFC) data all are configured on home subscribed services device (HSS);
Step 2: when home calling session control server (S-CSCF) carries out initialization, download all initial request filtercondition (iFC) data from home subscribed services device (HSS), the ID that comprises each initial request filtercondition (iFC), home subscribed services device (HSS) inform the pairing ID of home calling session control server (S-CSCF) initial request filtercondition (iFC); In user registration course, when home calling session control server (S-CSCF) obtained initial request filtercondition (iFC) data to home subscribed services device (HSS), home subscribed services device (HSS) was only informed the ID of home calling session control server (S-CSCF) initial request filtercondition (iFC);
Or when the user sends register requirement, home subscribed services device (HSS) is handed down to home calling session control server (S-CSCF) with the ID of initial request filtercondition (iFC), judge by home calling session control server (S-CSCF) whether the related data of initial request filtercondition (iFC) ID that should the user is downloaded, if do not download, then to complete initial request filtercondition (iFC) data of home subscribed services device (HSS) request user.
In step 2, after S-CSCF downloaded and preserved the IFC data, if HSS has revised the IFC in the user contracting data, the IFC that is preserved by HSS notice S-CSCF changed, and the IFC after will changing sends to the modification that S-CSCF is correlated with.
In the such scheme, when home calling session control server (S-CSCF) carries out initialization, download all initial request filtercondition (iFC) data, realize by FTP, SCTP, TCP from home subscribed services device (HSS).
In such scheme, send the user under the situation of acquisition request initial request filtercondition, first user sends register requirement, home calling session control server (S-CSCF) is to this user contracting data of home subscribed services device (HSS) acquisition request, home subscribed services device (HSS) returns initial request filtercondition (iFC) data, and carry the share I D of this initial request filtercondition (iFC) data, write down home calling session control server (S-CSCF) simultaneously and obtained these initial request filtercondition (iFC) data of sharing; When the user of back initiates register requirement, home subscribed services device (HSS) returns the ID of initial request filtercondition (iFC) data, and home calling session control server (S-CSCF) just can obtain initial request filtercondition (iFC) data of user's use of initiating register requirement in the back according to ID; If home calling session control server (S-CSCF) be can not determine shared initial request filtercondition (iFC) data, home calling session control server (S-CSCF) is initiated the subscription data request of subsequent user again, require complete transmission initial request filtercondition (iFC) data in the request, home subscribed services device (HSS) returns complete initial request filtercondition (iFC) data and its ID.
The present invention has effectively solved original scheme with the complicated problem of each NE management of network because of S-CSCF no longer disposes the data of iFC, kept that former share I FC brings simultaneously substantially be beneficial to.

Embodiment
Utilization the present invention realizes sharing the iFC technology can adopt multiple specific embodiments:
Scheme one: when initiating to ask, the user obtains the scheme of iFC, as Fig. 3:
Step 301:S-CSCF receives the register requirement of user A;
Step 302:S-CSCF is to HSS acquisition request user A subscription data, and this shared iFC that obtains is that S-CSCF obtains request for the first time, and HSS returns the iFC data, and carries the share I D of this iFC, writes down S-CSCF simultaneously and has obtained this iFC that shares;
Step 303:S-CSCF receives the register requirement of user B;
Step 304:S-CSCF is to HSS acquisition request user B subscription data, because user B uses the iFC identical with user A, and S-CSCF obtained the iFC of user A, and HSS returns the ID of iFC, and S-CSCF just can obtain the iFC of user B use according to ID;
Further, can not determine shared iFC at 304 S-CSCF, S-CSCF initiates the request of user B subscription data again, requires complete transmission iFC data in the request, and HSS returns iFC partial data and its ID.
When scheme two S-CSCF carry out initialization, download the scheme of iFC from HSS, as Fig. 4:
Initiate to share iFC to the HSS of ownership when step 401:S-CSCF starts and obtain request, can pass through FTP, SCTP or TCP, but be not limited to upper type;
Step 402: if HSS supports iFC, then HSS sends to S-CSCF and shares iFC and corresponding ID, if do not support, then responds NOT-SUPPORTED;
Step 403: user A initiates to be registered to S-CSCF;
Step 404:S-CSCF obtains the subscription data of user A to HSS,
Step 405: if HSS supports iFC, the HSS judgement has been downloaded relevant shared iFC to S-CSCF, so return the ID that shares iFC, S-CSCF is according to the shared iFC of the ID acquisition user A correspondence of sharing; If HSS does not support iFC, then return the related data of the iFC of respective user.
