Embodiment

For making the embodiment of the invention clearer, introduce below in conjunction with accompanying drawing.

IFC is made up of service trigger condition and corresponding AS information thereof.The service trigger condition comprise one or more service point triggers (Service Point Trigger, SPT), the method that service point triggers can be through logical expression (with or, non-) combine.Then be triggered to corresponding AS during service trigger condition coupling.

The structure of SPT can be consulted Fig. 1, wherein Request URI sign initial request resource pointed; SIP Mehtod representes the type of this request; SIP Header comprises the information relevant with this request; SessionCase has three possible values, initial, stop or stop unregistered; Session Description, definition is to the service point triggers of any SDP field contents in the SIP method body.In order to express easily, the embodiment of the invention will be defined as the initial request trigger point according to the service point triggers that the information that initial request is carried is mated, and this initial request trigger point comprises a kind of and combination in any among above-mentioned five kinds of SPT at least.

The embodiment of the invention is expanded above-mentioned iFC trigger mechanism in order to realize strengthening the purpose of service trigger.Through expansion iFC SPT type; The user's registration information that utilizes S-CSCF to preserve at user's registration phase carries out service trigger; Specifically can be divided into these several aspects: at first need expand iFC and support this new SPT of user's registration information trigger point (Registrationer Information SPT, RI SPT); S-CSCF preserves user's registration information at period of registration according to pre-configured scheme; After receiving initial request,, then mate at last, determine whether initial request is triggered to the application corresponding server according to the result of mating with user's registration information if comprise RI SPT among the iFC.

See also Fig. 2, be the network architecture diagram of the embodiment of the invention.

In this network architecture, S-CSCF is saved to the RI memory cell at user's period of registration with user's registration information (RI), and downloads the user data that comprises iFC.After receiving initial request,,, then carry out the initial trigger criteria match, if coupling just is triggered to corresponding AS, and then is routed to next jumping with the log-on message log-on message of being preserved if comprise RISPT among the iFC according to the iFC configuration.Wherein the RI memory cell is a S-CSCF internal logic function.HSS preserves user data in home network, when the user registers, the S-CSCF that serves for this user will download the user data that comprises iFC from HSS.The business that AS contracts by the user is carried out correspondent service logic control.

At first, expansion iFC supports user's registration information this new SPT of trigger point.Trigger condition among the iFC is described with SPT, and the SPT in the embodiment of the invention has expanded the log-on message trigger point, and its structure is shown in Figure 3.

The registration message trigger point is used to mate the required user's registration information of service trigger, and required log-on message can be user's entrained any information when registering.For example, it comprises but is not limited to one of ability of user terminal (UECapbility), customer position information, user accessing information or its its combination in any.

When the user had a plurality of terminal, the log-on message SPT among the iFC looked the service trigger demand, for the logical combination of the corresponding log-on message in a plurality of terminals (with or, non-).For example, can be that the log-on message at each terminal all must mate the AS that just is triggered to correspondence, there is the log-on message coupling at a terminal promptly to be triggered to corresponding AS as long as can also be.

Then, S-CSCF preserves user's registration information at period of registration according to the user's registration information preservation scheme that is pre-configured among the S-CSCF.At this, user's registration information preservation scheme has following two kinds:

1) S-CSCF preserves whole registration message get off after user's register and authentication success, comprise the SIP header field and the parameter of being with and sip message body.This scheme realizes simple, and favorable expandability.

2) header field, parameter or the message body in the log-on message of S-CSCF preservation appointment.The appointment of header field, parameter or message body needs according to user's service trigger.For example, the header field of appointment comprises but is not limited to Geolocation (positional information), P-Access-Network-Info (Access Network information); Designated parameters includes but not limited to the feature tag parameter (user capability information) in the Contact header field.

When the user has a plurality of terminal, should preserve a plurality of log-on messages accordingly among the S-CSCF.

At last, after receiving initial request,, then carry out the iFC coupling, if coupling then is triggered to corresponding AS with RI information if comprise log-on message SPT among the iFC.When the user has a plurality of terminal, then utilize a plurality of log-on messages and iFC coupling, if coupling then is triggered to corresponding AS.

What need explanation a bit is, if the user does not carry the required user's registration information of professional match triggers when registering, then receive initial request after, S-CSCF ignores log-on message SPT, matees other SPT and gets final product.

Therefore after adopting the log-on message trigger point of embodiment of the invention expansion; The concrete grammar of service trigger is: service-call session control function is preserved user's registration information and is downloaded initial filter criteria; The trigger condition of this initial filter criteria comprises log-on message trigger point and initial request trigger point; After then receiving user's initial request, mate one by one the user's registration information and the said log-on message trigger point of information that comprises the steps: said initial request is carried and said initial request trigger point, said preservation; Determine whether this initial request is triggered on the application corresponding server according to matching result

Embodiment one

User A carries out the IMS registration with the terminal with CSI ability.If IFC do not have extended registration information SPT, do not support the dynamic service active indication (DynamicService Activation Info is in the time of DSAI) when CSI service has been applied to network and CSI AS; No matter whether user A have the CSI ability as called terminal as called, and the request that caller is initiated all can be routed to CSI AS; CSI AS will be for carrying out successor operation; Be the called corresponding business that provides, if this moment, called terminal did not have the CSI ability, this business will be failed.

See also Fig. 4 and Fig. 5; Adopt the method for the embodiment of the invention; S-CSCF can obtain terminal ability information in the IMS registration process, after S-CSCF receives SIP INVIT message, utilize terminal ability information to go to mate the log-on message trigger point among the iFC; If coupling then be triggered to CSI AS (as shown in Figure 4) is if match and then be not triggered to CSI AS (as shown in Figure 5).
