As a core component of the intelligent network, the service control point device can directly or through the signaling network to access the data in the service database (SDP for short), It can also be connected to intelligent peripherals and service switching point equipment (SSP/IP) through the signaling network.

When the service control point device handles the custom ring back tone service, usually the user of the service dials the special service number or goes to the corresponding portal website to customize his own ring back tone. When other users dial the user's mobile phone, he hears The ringtone is the music customized by the caller, instead of the original stereotyped, monotonous ringing. The CRBT service solutions are mainly divided into two categories, one is based on switches, and the other is based on intelligent networks. The intelligent network solution is to modify the playback process of the original process through the intelligent network control mode to realize the service in the original call process, and the core of realizing the CRBT service under the intelligent network control mode is the intelligent network service control point device.

However, the intelligent network service control point equipment in the CRBT service does not have the function of copying the called ring tone for the calling user, but this requirement exists among the CRBT users: when the calling party who is also the CRBT user is in the When I make a call, I hear the CRBT tone I am interested in, and I really want to use it in my own CRBT service, and most of the time I want to obtain the use of the called party's current CRBT without going through the called party.

Based on the above situation, the present invention provides an intelligent network service control point device capable of duplicating CRBT. By using the present invention, the calling user can copy the CRBT currently used by the called user while waiting for the called party to answer, and does not Need the called user to provide help, directly obtain the currently heard color ring tone identifier, and use the currently called color ring tone on the local machine in the future.

The CRBT copying module 303 is configured to copy the current CRBT tone of the called user to the calling user record according to receiving the request of the calling user to copy the CRBT.

The intelligent network service control point device can receive the request signal of the intelligent peripheral device and the service switching point device to request to establish the ring tone voice channel through the copying ring tone request interface module 302, and generate a response signal; the calling request can be judged by the ring tone copying module 303 Information, record the caller information corresponding to the requested information and the CRBT to be copied in the service database; it can be connected with the intelligent peripherals and the service exchange point equipment, transmit the CRBT service trigger information, instruct to play the CRBT information, and transmit the caller Enter information.

As shown in Fig. 2, it is a system structure diagram for realizing CRBT duplication by using the embodiment of the present invention.

In Fig. 2, each label is respectively: 1, caller incoming call 2, called terminal (CRBT user machine) 3, called home switch 4, No. 7 signaling and voice channel 5, intelligent peripheral and service switching point equipment (IP/SSP) 6, INAP message 7, intelligent network service control point device (SCP, or ring back tone service server).

The SCP (7) is connected with the IP/SSP (5), uses INAP (6) as a communication protocol, and is used for transmitting CRBT service trigger information, instructing to play CRBT tone information, transmitting caller input information, and the like. The connection between the called home switch (3) and the IP/SSP (5) is the relay of No. 7 signaling and the voice channel (7), and one of its functions is to carry the color ring tone. There is also No. 7 signaling and a voice channel relay connection between the calling home switch and the called home switch (3).

In the process of listening to the color ring tone, if the caller enters information by pressing the button, such as pressing the button "1", it can be transmitted to the IP/SSP through the telephone switching network, the calling switch, and the called switch in the form of DTMF signals, etc., and the IP /SSP reports the operation result of the INAP message to the CRBT service logic software on the SCP.

The database used by the software to store business data is also installed on the SCP device, and the data structure and storage space for recording the copied ring tones are preset for each user.

As shown in Figure 3, it is a schematic flow diagram of the signaling process of copying the color ring tone process in the embodiment of the present invention, and its steps are:

1. The calling party dials the called phone number, and the No. 7 signaling IAM message reaches the called home switch.

2. The called home switch sends an IAM message to the IP/SSP according to the attribute of the local user (the attribute of the CRBT), and is used to establish a channel for playing the CRBT tone.

3. The CRBT IP/SSP sends an INAP IDP message to the CRBT service server to trigger the business logic software on the CRBT service server.

4. The CRBT service server sends an RRBE message to the IP/SSP.

5. The CRBT service server sends an ETC message to the IP/SSP, instructing the SSP to connect to the sound resource on the IP and prepare to play the ring tone; the IP/SSP responds with an ACM message to the called home switch.

6. The CRBT service server sends a P&C message to the IP/SSP, instructing the IP to play the ring tone.

7. The IP plays the ring tone, and the caller hears the ring tone.

8. Caller key input, intended to copy the current ring tone.

9. The signal input by the calling key is transmitted to the IP/SSP through the called home switch.

10. The IP/SSP reports the P&C result to the CRBT service server.

11. The CRBT business logic software judges that the caller wants to copy the current CRBT tone according to the P&C result, and judges that the calling user is a service user belonging to the CRBT system, and then records the currently playing CRBT in the service data of the calling user. ring tone, and set the "Copied" flag.

12. After the CRBT service completes the previous operation, it sends a PA operation message to the IP, and plays a voice to prompt the user: the ring tone is copied successfully.

13. The CRBT service sends a PA operation message to the IP, and continues to play the CRBT tone.

14. When the called party picks up the phone or is not connected, the called switch sends a REL message to the IP/SSP to release the ring tone channel of the CRBT system.

15. The IP/SSP reports an ERB message to the SCP to report the end of the call.

16. The SCP responds to the RC message to the IP/SSP and releases the call.

17. The IP/SSP responds the RLC message to the called switch to confirm the release of the call, and the logic related to the CRBT ends.

As shown in Figure 4, it is a schematic diagram of business process processing in the embodiment of the present invention, describing the process of the CRBT service logic software on the SCP processing the duplicated ring tone:

(Step 401) The calling party dials the called phone, the call arrives at the called home switch, and the called home switch sends a signaling message to the IP/SSP according to the local user attribute (color ring attribute), and notifies the IP/SSP to play the color ring tone.

(Step 402) The IP/SSP triggers the CRBT service logic software on the CRBT service server.

(Step 403) The CRBT service instructs the IP/SSP to play the CRBT tone and collect user input at the same time.

(Step 404) The calling party hears the ring tone.

(Step 405) Calling key input.

(Step 406) The signal input by the calling party is transmitted to the IP/SSP.

(Step 407) The IP/SSP reports the user input information to the ring back tone service server.

(Step 408) The CRBT service logic judges that the calling party intends to copy the current CRBT tone, and judges whether the calling user is a CRBT user belonging to the system, if so, turn to step 0, otherwise turn to 0.

(Step 409 ) The CRBT service records the identifier of the current CRBT tone in the attribute data of the calling user, and marks the status of the CRBT tone as "copy".

(Step 410) The CRBT service plays a voice prompt: the ring tone is copied successfully.

(Step 411) The CRBT service continues to play the current CRBT tone.

(Step 412) The called home switch sends a signaling to notify the IP/SSP to stop playing the CRBT.

(Step 413) The IP/SSP reports the event to the CRBT service server.

(Step 414) The CRBT service stops playing and releases resources.

(step 415) end.

The embodiment of the present invention can also realize the duplication of the ring tone of the called user by the following method:

Step 1, when the call to the CRBT user arrives at the called home switch, the called home switch requests the IP/SSP to establish a CRBT voice channel, and the IP/SSP sends a message to the SCP, requesting to play the CRBT.

In step 2, the service software logic on the SCP is triggered to play the color ring tone according to the user setting, and instruct the IP/SSP to collect the input information of the calling user, and wait for the IP/SSP to report the message.

Step 3, the calling party hears the ring tone; if the calling user inputs information on the terminal, the telephone switching network transmits the corresponding signal to the IP/SSP, and the IP/SSP reports the user input result to the SCP.

Step 4, the SCP judges that the calling user's input is to copy the current CRBT tone, and judges that the calling user is also a service user belonging to the CRBT system, so it records in the service database that the calling user has copied the current CRBT tone of the called party. ring tone.

Step 5, when the called user or the call fails to connect, the called home switch releases the voice path to the IP/SSP, and the IP/SSP reports a message to the SCP, and stops playing the ring tone.

Step 6, the CRBT copying system sends notification information such as voice information or short message information to the calling user according to the ring tone identifier copied by the service user recorded in the service database, informing the user that the copying operation is successful, and the calling user is asked to press the button to confirm the charge, and after getting The calling user records the charging information after confirmation.
