Abstract

The present invention discloses a method for realizing interaction between a service control point and an intelligent peripheral, which is used for the mutual interaction of information between a service control point (SCP) and an intelligent peripheral (IP) when a system in an intelligent network calls actively. The method comprises that: a plurality of a subscriber needs calling actively is acquired; a link between the SCP and the IP is established by sending a request, and the SCP indicates a service switching point (SSP) to establish a connection with the IP; the SCP sends script running (Script Run) operation to the IP which starts the script process specified in the operation; the IP sends a call to the number of the subscriber by the service switching point actively and establishes a talk.

Description

The implementation method of a kind of service control point and intelligent peripheral interaction

Technical field

The present invention relates to intelligent network technology, relate in particular to the implementation method of service control point and intelligent peripheral interaction when system initiatively breathes out in intelligent network.

Background technology

At present, Service Control Point and ip intelligent peripherals (Intelligent Peripheral in the intelligent network system, IP) there is a kind of UIScript (User Interaction Script) interface (to comprise: ScriptRun between, ScriptEvent, ScriptInformation, four operations of ScriptClose), this interface can transmit the information between SCP and the IP, thereby form a kind of business solution, provide such as business such as phonetic dialings.Be that example illustrates its typical usage with the phonetic dialing business below.

So-called phonetic dialing business is exactly that the user is kept at the personal phonebook in the system of telecommunications in advance, need not to import the other side's telephone number when making a phone call, and says the other side's name, is discerned and is continued by system.Its networking as shown in Figure 1, basic procedure is as follows:

1, the user calls;

2, (Service Switch Point SSP) notifies SCP user to call this incident to Service Switching Point;

3, SCP according to destination Mobile Station International ISDN Number inspection find that this is the phonetic dialing business, issue command request SSP and set up and being connected of IP;

4, the SSP request connects with IP;

5, IP returns response; Report request to give SCP simultaneously;

6, SCP issues ScriptRun and instructs to IP, requires IP to start the shell script of its appointment;

7, IP carries out shell script, and with user interactions, the user says the information such as name (as: connecting Zhang San) that hope is connected, and IP is mutual with the database D B of storage user's telephone directory, and technology such as use speech recognition match the user of telephone directory and confirm with the user.

8, after the user confirmed, IP reported SCP request SCP with called telephone number and is routed to called;

9, send instructions under the SCP and remove being connected between SSP and the IP, and require SSP to be routed to called number;

10, SSP is routed to called.

Above-mentioned flow process is that a typical case of UIScript interface between SCP and the IP uses, as seen this interface comprehensively the ability of SCP and IP a kind of solution of business is provided jointly.

Though the information interaction requirement that above-mentioned UIScript interface can satisfy the user when initiatively calling connecting system between SCP and the IP for the active call user's of system situation, can't be set up this interface between SCP and the IP, thereby can't be carried out information interaction.

Summary of the invention

This implementation method that a kind of service control point and intelligent peripheral interaction are provided, exist when solving the active call user of system in the prior art can't be mutual between SCP and the IP problem.

The implementation method of a kind of service control point and intelligent peripheral interaction realizes Service Control Point and ip intelligent peripherals (IP) interactive information when being used for initiatively breathing out in the intelligent network system; It is characterized in that the method comprising the steps of:

A, obtain and need the Subscriber Number of initiatively breathing out;

B, between SCP and IP, set up link by sending request;

C, SCP issue script operation (ScriptRun) operation to IP, are started the script flow process of appointment in this operation by IP;

D, IP initiatively make a call and set up conversation to described Subscriber Number by Service Switching Point.

In IP Run Script process, also undertaken mutual between IP and the SCP by script event (ScriptEvent) and script information (ScriptEvent) operation.

The present invention is by the existing interface of expansion SCP and IP, increase RequestBindSCF, RequestBindSRF and RequestBindSRF-Result operation, the communicating requirement of SCP and IP when well having realized the active call user of system, the present invention is applicable to fixed network and mobile network.

Embodiment

The active call user of system is a typical PUSH, generally is that the user has customized these business in advance, and these customization datas are kept in the database of system.

Consult shown in Figure 2ly, the present invention relates to four entities: Service Control Point, Service Switching Point, ip intelligent peripherals (IP) and customization database.Interface 1 between SCP and the IP meets CAMEL and Intelligent Network Application Protocol, and the interface 2 of SCP and SSP meets the CAMEL agreement, and the interface 3 of SSP and IP meets the TUP/ISUP agreement.

Be based on the interface 4 of internal agreement between SCP and the customer data base; Be based on the interface 5 of internal agreement between IP and the customer data base.User data is available as the external data base of SCP and IP, also can close with SCP or IP and establish.

The present invention sets up link at a pair of operation RequestBindSCF of increase and RequestBindSRF on the existing protocol basis between SCP and IP. and the exhalation of system can be initiated by SCP or IP.

Consult shown in Figure 3ly, learn that by the IP Query Database user who need to breathe out makes a call, its basic processing flow process is as follows:

(1) IP and customization database need to obtain the Subscriber Number of exhalation alternately.

(2) IP initiates the RequestBindSCF operation according to business need to SCP, and link is set up in request.

(3) after SCP receives the RequestBindSCF operation, issue ScriptRun (script operation) operation, require IP to start the script flow process of appointment to IP.

(4) just start the operation flow of appointment among the ScriptRun after IP receives.

(5) IP initiatively makes a call to the called subscriber by SSP and converses with called foundation.

Carry out in the operation flow at IP, also can send ScriptEvent (script event) operation and give SCP, SCP handles the back and returns ScriptInformation (script information) operation to IP.ScriptEvent between IP and the SCP (script event) operation and ScriptEvent (script event) operation can be carried out repeatedly according to service needed.

After finishing alternately, SCP can send ScriptClose and operate the operation flow of closing on the IP, and sends TC-END operation dismounting dialogue, perhaps removes dialogue by IP initiation TC-END.

Consult shown in Figure 4ly, learn that by the SCP Query Database user who need to breathe out makes a call, its basic processing flow process is as follows:

(1) SCP and customization database need to obtain the user of exhalation alternately.

(2) SCP initiates the RequestBindSRF operation requests according to business need to IP and sets up link, and waits for the response of IP.

(3) IP sends RequestBindSRF-Result (request binding SRF result) operation with return results to SCP, and SCP and IP set up communication link.

(4) SCP sends the ScriptRun operation to IP, requires IP to start the script flow process of appointment.

(5) just start the operation flow of appointment among the ScriptRun after IP receives.

(6) IP initiatively makes a call to the called subscriber by SSP and converses with called foundation.

Carry out in the operation flow at IP, IP sends ScriptEvent to SCP, and SCP handles, and returns ScriptInformation and give IP.ScriptEvent between IP and the SCP (script event) operation and ScriptEvent (script event) operation can be carried out repeatedly according to service needed.

Behind mutual the end, SCP can send ScriptClose and close operation flow on the IP, and sends the TC-END operation and remove dialogue, perhaps initiates TC-END by IP and removes dialogue.

Above-mentioned flow process can be applied on this class business of user's program request song very easily, but is not limited only to this business.As the birthday program request one first song of user to relatives, this song is called out and play in the system that is provided with at the 9:00 on same day birthday clock.The UIScript interface can satisfy professional requirement of chargeing according to the length and the content of song, and wherein, charging point is at SCP.

For RequestBindSRF and these two operations of RequestBindSCF, can adopt the coding rule with existing UIScript operation-interface, also can redefine coding rule.

The present invention has expanded the existing interface of SCP and IP, has increased RequestBindSCF, RequestBindSRF and RequestBindSRF-RESULT operation, the communicating requirement of SCP and IP when well having realized the active call user of system.The present invention is applicable to fixed network and mobile network.
