The connection between the narrowband called switch (or the called home switch) 106 and IP/SSP is No. 7 signaling and voice relay, and the connection between TG/SG and IP/SSP is also No. 7 signaling and Voice channel relay. An important function of the voice channel relay here is to carry the color ring tone. The TG/SG is connected to the broadband IP network, and can convert the voice channel relay voice signal into a broadband media stream voice signal and send it to the IP network, and the IP network or other media gateways transmit the voice to the calling party.

In the present invention, an intelligent network service software is loaded on the service control point equipment, and the service software analyzes the user attributes of the CRBT and controls the playing of the CRBT tone.

In the present invention, the narrowband called switch (or called home switch) has the following functions: when the call to the color ring user arrives, it can connect the voice path to the IP/SSP, or connect the called terminal and when the called terminal rings After ringing, initiate a call to IP/SSP.

In the present invention, the narrowband called switch (or called home switch) has the following functions: when the call to the color ring user arrives, it can connect the voice path to the IP/SSP, or connect the called terminal and when the called terminal rings After ringing, initiate a call to IP/SSP.

In the present invention, the called SS (or the called home SS) has the following functions: when the call message to the CRBT user arrives, if the called terminal starts ringing, it can send a message to TG/SG to instruct TG/SG Initiate a call to IP/SSP, and connect the IP call (via TG/SG) to the calling party.

2), the IP/SSP triggers the CRBT service logic on the SCP/APP according to the incoming call.

3), the CRBT service logic analyzes the CRBT user attributes according to the calling and called numbers, and instructs the IP/SSP to connect to the called party first if the voice path is detoured. The SSP plays the color ring tone, and instructs the IP/SSP to play the color ring tone directly according to the predetermined policy if the voice path is not detoured.

4) When the called party picks up the phone or the call is not connected, the CRBT service logic processes the message according to the message reported by the IP/SSP according to whether or not the voice path is detoured: when the voice path is detoured, the business logic instructs the IP/SSP to stop playing the CRBT tone , and connect the calling and called channels or release the call. When there is no roundabout channel, the narrowband switch will send a release call signal, and the business logic will instruct the IP/SSP to release resources.

After the above 4), the calling party and the called party start talking, or the system releases the calling resource.

The method for providing the ring back tone service to the broadband network is as follows:

1), when the call to the CRBT user arrives, the broadband switch first connects the called terminal according to the user attribute, and when the called terminal starts ringing, it sends a message to the TG/SG, instructing the TG/SG to initiate a call to the IP/SSP .

2), the IP/SSP triggers the CRBT service logic on the SCP/APP according to the incoming call.

3) The CRBT service logic analyzes the CRBT user attributes according to the calling and called numbers, and instructs the IP/SSP to play the CRBT tone according to a predetermined strategy.

4), IP/SSP transmits the color ring tone to TG through No. 7 signaling and voice relay between TG/SG, and TG/SG converts the color ring tone circuit signal into a data media stream, and passes through the IP network or other media gateways Finally, the ring tone is played to the calling party.

5) When the called party picks up the phone or fails to connect the call, the SS instructs the TG/SG to release the call to the IP/SSP, and the ring back tone service instructs the IP to release resources.

After the above 5), the calling party and the called party start talking, or the system releases the calling resources.

The processes related to the broadband and narrowband CRBT of the present invention will be described in detail below.

As shown in Figure 2, it is a schematic diagram of the CRBT path when the CRBT system plays CRBT for the narrowband network: IP102 plays the CRBT stored on it according to the instruction of the business logic on SCP 101, and the CRBT passes through IP102 → the called switch (the called party belongs to Ground switch) 106→calling party 107 such path is transmitted, if calling party 107 is also a narrowband user, this path is No. 7 signaling of narrowband network and the circuit channel.

As shown in Figure 3, it is a schematic diagram of the CRBT path when the CRBT system plays CRBT for the broadband network: IP plays the CRBT stored on it according to the instruction of the business logic on the SCP, and the CRBT passes through IP 102→TG+SG 103→IP network 105 (there may be a media gateway device in the middle) → the caller 108 is transmitted. Among them, between IP and TG+SG is the No. 7 signaling and circuit channel, and between TG+SG and IP network is IP media stream.

As shown in Figure 4, the following describes the signaling process when providing the CRBT service for the broadband network:

1. The call to the broadband called user arrives at the broadband network, and the SS receives the SIP signaling INVITE (call initiation) message.

2. The SS sends an INVITE message to the called party (or called gateway device).

3. The SS receives the SIP signaling ringing message 180 returned by the called party (or the called gateway device).

4. The SS analyzes the data of the called user: the called party has opened the ring back tone service, and then uses SIGTRAN to send an IAM (Initial Address Message) message to the SG on the IP network.

5. The SG sends the IAM message to the IP/SSP through the No. 7 signaling network.

6. The IP/SSP triggers the intelligent network CRBT service, and sends an IDP message to the SCP.

7. The SCP executes the CRBT business logic, sends an ETC message to the SSP, and indicates connection tone resources.

8. The SCP sends a VPA message to the IP/SSP, instructing the IP to play the CRBT.

9. The SSP sends an ACM message (full address message) to the SG through the No. 7 signaling network.

10. The SG uses the SIGTRAN protocol to forward the message ACM to the SS through the IP network.

11. The IP broadcasts the color ring tone according to the instructions of the SCP, and the color ring tone is transmitted to the TG through the narrowband telephone network.

12. The TG converts the narrowband CRBT circuit signal into a media stream packet, and sends it to the calling network through the IP network (may pass through the media gateway in the middle), and the calling party hears the CRBT.

13. The called party picks up the phone to answer, and the SS receives the SIP signaling message 200.

14. The SS sends a RELEASE (release) message to the SG to end the call to the CRBT system.

15. The SG sends a RELEASE message to the SSP.

16. SSP sends RC message to SCP.

17. The service logic on the SCP sends a DFC message to the SSP, instructing the SSP to release the audio resource.

18. The SSP releases the audio resource and returns an RLC message to the SG.

19. The SG sends an RLC message to the SS, and the call from the broadband network to the CRBT system ends.

20. The CRBT service of this call ends, and the SS resends the INVITE message to the calling party to negotiate the media flow with the calling party through the called SDP.

21. The caller returns a 200 message.

22. The caller-called media flow controlled by the SS is established, and the caller and the called party talk.

As shown in Figure 5, the following description is a signaling process when a narrowband network—GSM network provides color ring service:

1. The IAM message of the called party arrives at the MSC where the GSM network belongs.

2. The home MSC sends a MAP message SRI to the HLR to query the called user attribute data.

3.HLR returns SRI ACK (response to response), and the return message includes data such as whether the user opens the ring back tone service, current roaming number.

4. The home MSC sends an IAM message to the visited MSC where the called user's current roaming number is located.

5. The visited MSC pages the called user, and returns an ACM message to the home MSC.

6. The home MSC returns an ACM message to the calling side.

7. When the home MSC analyzes and finds that the called party is idle, checks the called user attribute, finds that the called party has opened the ring back tone service, sends an IAM message to the ring back ring system (IP/SSP), and initiates a call to the ring back ring system.

8. The CRBT system receives the IAM message, triggers the CRBT service logic, returns an ACM message and ANM message (response message) to the home MSC, and plays the CRBT tone.

9. The home MSC receives the ACM message and the ANM message, connects the call path between the calling party and the CRBT system, and the calling party hears the CRBT tone.

10. The called party picks up the phone to answer, and the visited MSC returns an ANM message to the home MSC.

11. The home MSC forwards the ANM message returned by the visited MSC to the calling party, and sends a REL message to the CRBT system, ending the call to the CRBT system.

12. The CRBT system returns an RLC message, and the MSC at the home location disconnects the voice channel between the calling party and the CRBT system, connects the voice channel between the calling party and the called party, and the calling party and the called party communicate.
