Description
Technical field
The present invention relates to intelligent network technology, particularly the relevant technology of intelligent call playback.
Background technology
Intelligent network (Intelligent Network, abbreviation " IN ") technology at lower cost rapidly, introducing new business is target in communication network neatly, adopt new-type network structure and control mode, need not to revise in a large number the software of switch, can provide various new business for the user fast.Intelligent network is the professional strong instrument that provides of a maturation, and characteristic services such as intelligent pre-payment, universal number, networking crisis phone only, Virtual Private Network can be provided.With intelligent prepayment service is example, and the user can use any phone to call out, and cost of the phone call will rather than be remembered on the phone bill of its use from its account number deduction; During per call, whether intelligent network is at first inquired about account number, password that this user dials in effective, and whether its account number remaining sum can be paid is this time called out; When end of conversation or remaining sum are used up, call information/charge information preserved to be provided with the back used.In China, 200,300 and the IP phonecard phone that people were familiar with is typical intelligent prepayment service.
Service Switching Point (Service Switching Point is called for short " SSP "), service control point (ServiceControl Point is called for short " SCP ") are the Main physical entities of two intelligent network physical planes.SSP is existing public switched telephone network (Public Switched Telephone Network, be called for short " PSTN "), integrated services digital network (Integrated Services Digital Network, be called for short " ISDN ") and global system for mobile communications (Global System for mobile Communication, be called for short " GSM ") etc. the tie point of network and intelligent network, it provides the function that inserts intelligent network function collection, mainly finish Service Switching Function (Service Switching Function, be called for short " SSF ") and CCF (CallControl Function is called for short " CCF ").SSP detects the request of IN service, and communicates by letter with SCP, and the request of SCP is responded, and allows the service logic among the SCP to influence call treatment.SCP is the core component of intelligent network, is used for storaging user data and service logic, and its major function is to receive Query Information and the Query Database that SSP sends here, carries out various decodings; Simultaneously, SCP can start different service logics according to the call event of offering on the SSP, sends the calling control command according to service logic to corresponding SSP, and indication SSP carries out next step action, thereby realizes various intelligent calls.Signaling System Number 7 agreement (Signalling System No.7 is adopted in the communication of intelligent network, be called for short " SS7 ") signaling, intelligent network application protocol in the SS7 signaling system (Intelligent Network Application Protocol is called for short " INAP ") is specifically designed to intelligent network communication.
In the intelligent network, professional and carrying separates, and service supplier does not need or only need do a spot of change to original network, just can provide professional to the user easily.This also is next generation network (Next Generation Network, be called for short " NGN ") an important characteristic very, business control and the carrying media of NGN are separated, the user can dispose and define the service feature of oneself voluntarily and needn't be concerned about the latticed form and the terminal type of bearer service, feasible business and the bigger flexibility that provides of using, thereby satisfy the business demand that the user is constantly developed renewal, also make network possess extensibility and quick ability of disposing new business, make the network operator more competitive.In the NGN network, soft switch is to be used to handle call signaling and the nucleus equipment of calling out control and business realizing.
Based on the network model of the intelligent network of NGN as shown in Figure 1.Wherein, INAP or INAP+ agreement are supported in soft switch, communicate as SSP in the intelligent network and SCP; Media Resource Server (MediaResource Server, be called for short " MRS ") be an application layer equipment, it receives the various command request from Softswitch, and communicate by letter with other key components that comprise gateway, terminal or application server in the network, provide medium resource service to them.
In the intelligent call process, usually need playing alert tones (BEEP).For example, in intelligent prepayment service, just may need to the calling subscriber playing alert tones, remind caller better to grasp the duration of call.
In the prior art scheme, realize the broadcast of prompt tone by the mode of alerting tone.SCP carries the alarm prompt parameter in the standard A C of the Intelligent Network Application Protocol that sends to SSP operation, the broadcast of prompt tone is mainly realized by conferencing by the user side of speech business module.Wherein, conferencing is a kind of MPTY mode that a kind of needs take the tone playing equipment conferencing resource, uses conferencing to need the first to file conferencing resource usually, by tone playing equipment audio frequency is carried out audio mixing then to user's playback the time and handles, and sends to the user again.
In actual applications, there is following problem in such scheme: the first, and the prior art scheme needs more system resources, may influence speech quality; The second, the prior art scheme can't dispose the voice document of broadcast arbitrarily, and extensibility is not strong; The 3rd, the prior art scheme can only be at the particular moment playing alert tones, and flexibility is little.
Cause the main cause of this situation to be, the first, the prior art scheme is used the conferencing playing alert tones, and the conferencing resource that conferencing uses need take bigger system resource, therefore the performance to switch has certain influence, may influence speech quality; The second, prior art scheme prompt tone can only use the employed prompt tone of conferencing, and voice document is normally fixed, and can't utilize MRS to go up abundant voice resource, therefore can only play some fixing basic tips sounds, and extensibility is not strong; The 3rd, the prompt tone that the prior art scheme is play comes down to a kind of alerting tone, only just begins to play when arriving alarm time, and the periodicity of carrying out in the time of can't realizing from the conversation beginning is play, and flexibility is little.
Summary of the invention
In view of this, main purpose of the present invention be to provide a kind of in intelligent call the method for playing alert tones, make under the situation that does not take conferencing resource, the broadcast of periodic prompt tone is provided, and can use the various voice resources that comprise the MRS resource by the flexible configuration prompt tone.
