Step 101: call subscriber terminal (UE1) sends conversation request message, this request message arrives core net (CN, CoreNetwork).
Described conversation request message is the INVITE of session initiation protocol (SIP, SessionInitializationProtocol) agreement; Described core net, refer to CSCF (CSCF, CallStateControlFunction), home subscriber server (HSS, IP Multimedia System (the IMS such as HomeSubscriberServer), IPMulti-mediaSubsystem) server apparatus, common way, in the user data on HSS, the parameter that polychrome is relevant is set, by serving CSCF (S-CSCF, Service-CSCF) judge route according to the user data in HSS, and INVITE is first sent to polychrome server (Server).
Step 102: core net Forward-reques message is to polychrome server, and polychrome server performs local service logic, afterwards conversation message is delivered to called user terminal (UE2) through core net.
In this step, polychrome server can pass to UE2 the media description data of polychrome resource.
When step 103:UE2 is idle, return called idle message to core net, this message arrives polychrome server.
Described called idle message, can be 180 of Session Initiation Protocol just at ALERTING message, also carry the media description data of UE2 in message.
Step 104: polychrome server and UE2 set up media data and transmit and be connected, and polychrome data are sent to UE2.
In this step, the equipment of transmission polychrome data can be the special media device in polychrome server, as special media server stores polychrome resource, under the instruction of polychrome control system, connects, transmits polychrome media data with UE2.
In this step, UE2 can show polychrome media.
Step 105: polychrome server sends called idle message through core net to UE1.As mentioned above, called idle message can be 180 message.
After step 106:UE2 button is answered, UE2 sends called party answer message.Described called party answer message, specifically the 200OK message of Session Initiation Protocol.
Step 107: after polychrome server receives the called party answer message of UE2, stops transmitting polychrome media data to UE2, sends called party answer message through core net to UE1.As mentioned above, called party answer message specifically 200OK message.
Step 108:UE1 receives called party answer message, sends session establishment acknowledge message, arrives polychrome server through core net.Described session establishment acknowledge message is the ACK message of Session Initiation Protocol.
Step 109: polychrome server receives the session establishment acknowledge message of UE1, is transmitted to UE2 via core net.As mentioned above, session establishment acknowledge message is ACK message.
Step 110: color image service terminates, UE1, UE2 converse.
As above, the broadcasting of polychrome is determined by polychrome server in step 104.
The feature of existing color image playing method is, during each session, call subscriber terminal does not also know in the polychrome server in core net to be provided with what kind of polychrome service option, and whether core net and polychrome server are also indifferent to user terminal has special requirement to polychrome service.During actual use color image service, there is such situation: although calling subscriber has applied for that color image service is experienced to supply called subscriber, but calling subscriber may intend by a new polychrome to a specific called subscriber temporarily, or does not intend calledly to provide color image service to all; By normally used method, caller can do relevant setting to meet this requirement at polychrome server, but, this common solution one is that requirement calling subscriber must be connected to the corresponding setting of execution on polychrome server, actual will unusual inconvenience when using, although two is that calling subscriber arranges when not providing polychrome to experience to called subscriber, conversation message still can through polychrome server, this adds the extra disposal ability of system undoubtedly, causes the waste of Internet resources.

Step 201: network side obtains the polychrome broadcast strategy in the conversation request message of call subscriber terminal.
In the present invention, before calling subscriber utilizes call subscriber terminal to make a call to called user terminal, polychrome broadcast strategy can be set for called user terminal, namely determine whether be that called user terminal plays polychrome, if when playing, play which polychrome, when not playing, the indication information not playing polychrome is set, namely indicates and do not play polychrome to called user terminal.Play the indication information that only can comprise in polychrome strategy and play polychrome, after network side gets polychrome broadcast strategy, if comprising the indication information playing polychrome, but not for playing the identification information of polychrome, then in polychrome server by the CAMEL-Subscription-Information of calling subscriber be called user terminal play polychrome, or an optional polychrome is that called user terminal is play.The implication playing the indication information of polychrome is designated as called user terminal to play polychrome.Play in polychrome strategy the identification information that can only comprise for playing polychrome, after network side gets polychrome broadcast strategy, according to comprising the identification information for playing polychrome, for called user terminal plays polychrome corresponding to the identification information of polychrome.The identification information of polychrome comprises code information or URL(uniform resource locator) (URL, the UniformResourceLocator) information of polychrome.Certainly, play in polychrome strategy the identification information of identification information and the wish broadcasting polychrome that both can also comprise and play polychrome, after network side gets polychrome broadcast strategy, according to comprising for playing the identification information of polychrome, for called user terminal plays polychrome corresponding to the identification information of polychrome.
After network side gets polychrome broadcast strategy, if comprise the identification information not playing polychrome, then directly set up session for described call subscriber terminal and described called user terminal, call flow need not again through polychrome server.
In the present invention, polychrome broadcast strategy is carried by conversation request message.
Step 202: network side performs polychrome broadcast strategy.According to identification information concrete in polychrome broadcast strategy, play polychrome for called user terminal or directly set up session for described call subscriber terminal and described called user terminal.
Fig. 3 is the flow chart of the concrete example of color image playing method of the present invention, and as shown in Figure 3, this example color image playing method comprises the following steps:
Step 301: before session start is set up, calling subscriber fills in conversation request message in call subscriber terminal (UE1), is sent to core net.
In this step, UE1 uses REJECT-CONTACT heading field in INVITE, such as, fill in field value for " CRS-SERVER ", represents not use color image service (CRS) in this session.Certainly, calling subscriber also according to the situation of called subscriber, can arrange the concrete color image service being shown to called subscriber.
Concrete, by the set-up mode in following table for called user terminal (UE2) arranges concrete polychrome broadcast strategy, concrete polychrome broadcast strategy is as shown in table 1:
| Called number | Polychrome identifies |

Step 302: conversation request message arrives core net, core net forwards conversation request message to called user terminal (UE2).
In this step, when S-CSCF in core net is checked through in conversation request message the shielding color image service instruction having REJECT-CONTACT:CRS-SERVER such, ignore the polychrome parameter that in HSS, user data is relevant, not Message routing to polychrome server, but be directly sent to terminal called, as the not signing color image service of caller.Certainly, if comprise concrete polychrome identification information, then extract the polychrome identification information in conversation request message, and send to polychrome server, find out concrete color image service by polychrome server according to polychrome identification information, and send to UE2.Concrete, when UE1 initiates a session request message, the instruction using which polychrome resource is filled in conversation request message, SIP heading field ACCEPT-CONTACT can be used to realize the instruction of polychrome, such as fill in CRS server and polychrome mark: CRS-SERVER/ct00011 in field value part, the transmission of instruction polychrome server is designated the polychrome of ct00011 to called user terminal.When comprising ACCEPT-CONTACT field and concrete polychrome identification information in conversation request message, idiographic flow and the flow process shown in Fig. 1 of polychrome broadcasting are similar, difference is that the maker of polychrome broadcast strategy is different, determined according to CAMEL-Subscription-Information by polychrome server in Fig. 1, and the present invention is determined by calling subscriber, be sent to by after compared with the polychrome of user determining, the flow process being sent to called subscriber is identical with Fig. 1, here repeat no more, handling process when comprising REJECT-CONTACT field is below described.
When step 303:UE2 is idle, return called user terminal idle message to core net.
Step 304: core net sends called idle message to call subscriber terminal.
Step 305: after called subscriber's button is answered, called user terminal sends called party answer message.
Step 306: core net sends called party answer message to call subscriber terminal.
Step 307: call subscriber terminal receives called party answer message, sends session establishment acknowledge message, arrives called user terminal through core net.
Step 308: directly set up call between caller is called.
Above-mentioned example, achieve the shielding to the color image service in a session that call subscriber terminal controls, this shielding mode does not need service-user parameters on the server, and decreases taking and consumption to server-capabilities Internet resources.That is, polychrome server need not store in advance the polychrome CAMEL-Subscription-Information of each user terminal, and polychrome broadcast strategy in the conversation request message directly made a call according to user terminal and carry out the playback process of polychrome, polychrome broadcast strategy of the present invention is formulated more flexible, when polychrome need not be shown to called subscriber, call flow through polychrome server, thus need not save the process resource of network side.
