Embodiment

Describe the embodiment of the invention in detail hereinafter with reference to accompanying drawing, wherein, provide following examples with provide to of the present invention comprehensively and thorough, rather than the present invention carried out any restriction.

In the present embodiment, provide a kind of Multimedia Caller Identification Service implementation method, wherein, the medium color image service in IMS territory is open towards the user of all IMS.

In the method, call out the calling subscriber who has opened Multimedia Caller Identification Service under called subscriber's the situation, before the called subscriber answers conversation, terminal called will be shown to the called subscriber from the polychrome that network obtains, wherein, polychrome comprises the picture that set in advance by the calling subscriber, literal, video, audio frequency etc., and it can be commonly referred to as the polychrome resource.

If realize the broadcast of polychrome, need in IMS core net (IMS core), some business datums and user data be set, require terminal to possess the ability of uploading or downloading the polychrome file and play to the polychrome server by the http agreement, preferably, following terminal can be softDA software terminal or 3G mobile terminal.

Preferably, the setting of business datum and user data can be carried out in advance, particularly, following processing can be comprised:

Go up signatory play number at home location server (HSS): for the polychrome user, for example, ID is 24020011 user, can increase a private user identity for this user, for example, this thinks friendly sign can be 24020011@ln.chinamobile.com, and for this user increases by three public subscriber identifications, for example, public identifier is sip:24020011@ln.chinamobile.com, tel:24020011 and sip:ln0011@ln.chinamobile.com, afterwards, private user identity and three public subscriber identifications are mapped.Like this, this user just can (24020011, tel:24020011 ln0011) lands softDA or be used for 3G mobile terminal call the other side with any public subscriber identification;

Afterwards, on HSS, increase a service template service profile who points to PSS, and the polychrome user business type that all are opened is all pointed to this template service profile.This is the effect of a route just, and how the CSCF (CSCF) at indication user place finds PSS in the subscription data of the user among the HSS, per call, and the user only is triggered on the PSS, could trigger the business on the polychrome application server (AS);

Next, on PSS, increase the template of a color image service, the polychrome user is registered as this template, owing to Multimedia Caller Identification Service is present on the PSS as a kind of supplementary service, so PSS finds polychrome MS to trigger business according to the server address in the template;

Link and the route that is routed to CRBT center (CRBT) system is set on the maintenance console of CSCF.Make all callings after handling on the CSCF, obtain the uniform resource locator (URL) and the downloading and playing of polychrome file to CRBT system business platform.

In method, preferably, can be responsible for by the PSS of IMS core continuing according to the embodiment of the invention.Like this, each service call only takies a signalling path, a called off-hook is just removed the session channel of CRBT system, so, can save system resource to a great extent, guarantee high-speed data transmission, and can clarification in certain roles, make the CRBT system only be responsible for continuing of the not responsible calling of service logic, avoided the appearance of alternative channel, guaranteed the reliability of CRBT system.

In addition, before playing polychrome, can also carry out following processing in advance: distinguish the medium of Ring Back Tone service and the medium of color image service by the field that expands medium type.This be because, in realizing the video polychrome, be again color ring user if the called subscriber is the polychrome user, at this moment to the situation of polychrome and CRBT Early Session is arranged simultaneously, needing to distinguish which medium be CRBT, which medium is polychromes.For example, can define MCTD Session and CRBTSession, example is as follows:

Content-Type：application/sdp

Content-Disposition：x-mcid-session

Content-Disposition：x-crbt-session

It is advantageous that:, CRBT medium and polychrome medium have been carried out clearly distinguishing, and do not needed Session Description Protocol (SDP) is expanded by expanding contents processing type (Content-Dispositiontype); In addition, concerning the intermediate NE of IMS core net, for the medium type of the expansion that can not discern, only need carry out transparent transmission, and the situation that mistake is handled can not occur.
