Description
(1) technical field
The present invention relates to a kind of method that realizes multi-colour return-bell sound business, especially in fixed communication network, realize the method for multi-colour return-bell sound business.
(2) background technology
Multi-colour return-bell sound business (Color Ring Back Tone; CRBT) also claiming personalized ring back tone service, be called for short CRBT, is to be the ring-back tone that other calling subscribers of calling out own phone set special sound effect by the called subscriber.In telephone call, before called subscriber's off-hook is replied, what the calling subscriber heard will no longer be the ringring prompting sound of dull " pouting ... pout ... ", but the Customized Ring Back Tone of in system, setting by the called subscriber, ring-back tone can be one section music or advertisement, or called subscriber's message of setting etc. of controlling oneself.
Ring Back Tone service is at first realized on mobile communications network.But will be used for Ring Back Tone service on the mobile communications network is used for fixing communication network and then has certain difficulty.Its reason is because online at mobile phone, and each is called out, and not only the user of caller is had the flow process of an authentication, called user is also had the process of an authentication and definite its current position.And Ring Back Tone service be one by called subscriber institute business of triggering.In mobile radio communication, when the caller switch can obtain called CAMEL-Subscription-Information to called when carrying out authentication very naturally, in case after the switch of caller has obtained called information of whether applying for Ring Back Tone service, just can be easy to realize providing or not providing Ring Back Tone service.
And on the fixed communication network, not to called this process of carrying out authentication, if realize Ring Back Tone service, relatively the method for nature will inevitably relate to the flow process of former switch is made amendment, and its cost is sizable.For with this service application in fixed communication network, some manufacturers have proposed solution, and are relatively more typical in IP (Intellectual Peripheral) bridging solution.
Fig. 1 has shown as calling subscriber and called subscriber and has been positioned under the situation of same terminaling exchange that IP bridge joint scheme realizes the process of multi-colour return-bell sound business.In Fig. 1, user A and user B all are connected to switch (the Local Exchange of same terminal station; LEX) on, this terminal station switch and a Service Switching Point (Service Switch Point; SSP) link to each other, this Service Switching Point is usually located at the tandem aspect.Above-mentioned Service Switching Point connects a service control point (Service Control Point; SCP) and an intelligent peripheral (Intellectual Peripheral; IP).This service control point is used for controlling the call flow of multi-colour return-bell sound business, and command adapted thereto is sent to SSP, and this intelligent peripheral then stores and multi-colour return-bell sound is provided.If user A initiates a call to user B, then A is the called subscriber for calling subscriber B, calling subscriber A attempts to set up calling with user B via terminaling exchange (LEX), but because this terminaling exchange can not provide Ring Back Tone service, therefore called subscriber B makes subscriber call A this calling stress newly to be routed to the calling subscriber and can support Ring Back Tone service to have the tandem exchange of SSP function.SSP notice SCP carries out flow process control.At first transmitting control commands is to SSP for SCP, and SSP sends order again to this terminaling exchange then, arrives called subscriber B.If it is normal and idle that SCP learns the state of called B, it can arrive above-mentioned IP by transmitting control commands, and order IP give calling subscriber's coloring ring back tone playing.This CRBT sound finally arrives user A via SSP and terminaling exchange.
From above-mentioned flow process as can be seen, the shortcoming of the CRBT solution of this IP bridge joint is in order to use Ring Back Tone service, and per call needs and SCP carries out Signalling exchange, thereby takies a large amount of Internet resources, comprises trunk, signaling, voice etc.In addition, if the relaying between SCP and the SSP breaks down in calling procedure, perhaps SCP itself breaks down, and all can cause normal call setup to be affected.
Digital and electronic switching system (Digital Electronic Switching System in Siemens; EWSD) in, exist and line ringing (Parallel Ringing; PRNG) business.This PRNG business belongs to professional a kind of of Call Forwarding (Call Forwarding), and other Call Forwarding also has transfer immediately, transfer on no reply, call forward on busy etc.The flow process of concurrent frame bell as shown in Figure 2.
1) called subscriber B is that oneself specifies another Subscriber Number C.
2) when calling subscriber A when called subscriber B makes a call, switch A at first sends initial address message IAM (InitialAddress Message) 1 to switch b;
3) the switch b return address is finished message ACM (Address Complete Message) 1 and is given switch A, and sends initial address message IAM2 to switch C;
4) switch C finishes the return address message ACM2 and gives called subscriber's switch b;
5) called subscriber's switch b returns to call out and carries out message CPG (Call Progress) 1 to calling subscriber's switch A, and the calling subscriber begins to answer ring-back tone, and user B and user C are simultaneously in ring;
6) as if called subscriber B off-hook, then switch b sends response message ANM (Answer Message) 1 and gives switch A, and sends release message REL (Release) 2 to switch C; If another user C off-hook, switch C send response message 2 to switch b.Switch b discharges user B, sends response message 1 simultaneously to switch A.
Because above-mentioned parallel ring service is realized on EWSD equipment, if develop the bigger multi-colour return-bell sound business of another set of equipment needed thereby difference, will certainly greatly influence the utilization ratio of existing resource, causes many other extra expenses.
