1, calling subscriber A calls out called subscriber B, calls out to arrive SSP, and SSP is by HLR inquiry called subscriber's attribute, if called subscriber's number is the color ring user number, the then preceding IN service access code of inserting is triggered to SCP with calling;

2, SCP issues two connection numbers to SSP, comprises AIP number and called subscriber's number;

3, SSP makes a call to called subscriber B according to the connection number that SCP issues;

4, land end office (EO) to called subscriber B ring, and loopback ACM (Address Complete, the address is complete) message is to SSP;

5, after SSP receives ACM, initiate second party to AIP and call out, and the speech channel between connection calling subscriber A and the AIP; AIP sends the Comfort Noise Generation (CNG) of customization to calling subscriber A according to the number of called subscriber B simultaneously;

6, after called subscriber B off-hook was replied, SSP removed the calling of AIP, was communicated with the calling and called user, finished normally and continued.

Because Ring Back Tone service is for most of domestic consumers, be not to select color ring back tone from the website of the Internet, neither own editing CRBT, also be that the CRBT sound is by carrier customization, the investment of operator's construction intelligent equipment is just relatively large in this case, can not be that the user provides Ring Back Tone service to experience with lower investment and the fastest speed.Simultaneously, along with the development of Ring Back Tone service, this mode has also strengthened the load of color ring platform.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of operator need not drop into excessive equipment investment, just can carry out the system and method for the realization Ring Back Tone service of Ring Back Tone service rapidly.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of system that realizes Ring Back Tone service is provided, and this system comprises the media gateway MGW and the service switching point of calling subscriber, called subscriber, called subscriber's side; SSP inquiry called subscriber's attribute, if inquiring called subscriber's number is the color ring user number, and inquire the CRBT of called subscriber customization, then SSP is triggered to the MGW of called subscriber's side with calling, simultaneously by MGCP MGCP Extended Protocol or H.248 the MGW of Extended Protocol indication called subscriber side play the CRBT of called subscriber's customization; The MGW of called subscriber's side is after called subscriber's ring, and the MGW of called subscriber's side plays the CRBT of called subscriber's customization to the calling subscriber.

Described called subscriber's property store is in the central interior database of SSP.

Described MGCP Extended Protocol or H.248 Extended Protocol be to be used to indicate the MGW of called subscriber's side to play the CRBT of called subscriber's customization the signal id in the modification MODIFY message of MGCP/H.248 agreement.

For solving above-mentioned another technical problem, the technical solution adopted in the present invention is: a kind of method that realizes Ring Back Tone service is provided, and this method may further comprise the steps:

A, calling subscriber call out the called subscriber, call out to arrive SSP SSP inquiry called subscriber's attribute;

B, if the number that inquires the called subscriber is the color ring user number, and inquire the CRBT of called subscriber customization, then SSP makes a call to the called subscriber, simultaneously by the MGCP Extended Protocol or H.248 the MGW of Extended Protocol indication called subscriber side play the CRBT of called subscriber's customization;

The MGW of c, called subscriber's side is after called subscriber's ring, and the MGW of called subscriber's side plays the CRBT of called subscriber's customization to the calling subscriber, and at this moment the calling subscriber just can hear the CRBT that the called subscriber customizes;

After d, called subscriber's off-hook are replied, be communicated with the calling and called user, finish normally and continue.

The described MGCP Extended Protocol of step b or H.248 Extended Protocol be to be used to indicate the MGW of called subscriber's side to play the CRBT of called subscriber's customization the signal id in the MODIFY message of MGCP/H.248 agreement.
