The signatory CRBT of terminal called is play at step 302, CRBT center, sends ALERTING message to MSCe.
Step 303, playing the signatory CRBT of terminal called, and when the user of calling terminal does not want to listen terminal called user's signatory CRBT, calling terminal sends key information by the * key time and asks the CRBT switching.
Step 304, CRBT center detect the key information of calling terminal, know that calling terminal wishes to switch the signatory CRBT of terminal called; Mind-set MSCe issues the call progress message after the expansion in the CRBT.
Here, Event information field=7, the indication calling terminal need switch CRBT, interrupts the signatory CRBT of terminal called.
Step 305, CRBT center stop to play the signatory CRBT of terminal called, and send release message to MSCe.
Step 306, MSCe receive the call progress message after the expansion that the CRBT center issues, and after parsing the information that indication terminal called CRBT interrupts, know the CRBT that need switch to calling terminal; MSCe judges whether calling terminal opens Ring Back Tone service, if then execution in step 307; Otherwise, execution in step 309.
The signatory multimedia bell information of step 307, MSCe authentication calling terminal, authentication success back sends initial address message to the CRBT center, the signatory CRBT of indication CRBT center playing and calling terminal.
Here, be packaged with the number of calling terminal in the initial address message.
The signatory CRBT of step 308, CRBT center playing and calling terminal sends ALERTING message to MSCe; Execution in step 310.
The not signatory CRBT of the signatory multimedia bell information of step 309, MSCe authentication calling terminal, calling terminal causes failed authentication, and the MSCe indicating media gateway is play common ring-back tone to calling terminal.
Step 310, the current CRBT switching flow of end.
Method embodiment two is: calling terminal and terminal called are the user terminal of different MS Ce, i.e. calling between calling terminal and the terminal called is station to station call.At station to station call, calling terminal is not registered among the local MSCe, after the key information that detects calling terminal when the CRBT center starts CRBT and switches so, sends the call progress message after the expansion of indication CRBT switching to the MSCe of this locality.Because this local MSCe does not know the CAMEL-Subscription-Information of calling terminal, therefore MSCe that should this locality needs the call progress message after should expansion of transparent transmission forward, MSCe up to the strange land that is transparent to this calling terminal registration can judge that just the signatory CRBT of the calling terminal that continues is still play common ring-back tone.
So, in the present embodiment, the implementation method that CRBT switches may further comprise the steps:
Step 401, calling terminal are called out terminal called, and terminal called is opened Ring Back Tone service; MSCe sends initial address message to the CRBT center, and the signatory CRBT of terminal called is play at indication CRBT center.
Here, initial address message promptly is used for the message of call setup, is packaged with the number of terminal called in the initial address message.
The signatory CRBT of terminal called is play at step 402, CRBT center, sends ALERTING message for called MS Ce.
Step 403, called MS Ce send ALERTING message to caller MSCe; Playing the signatory CRBT of terminal called, and when the user of calling terminal does not want to listen terminal called user's signatory CRBT, calling terminal sends key information by the * key time and asks the CRBT switching.
Step 404, CRBT center detect the key information of calling terminal, know that calling terminal wishes to switch the signatory CRBT of terminal called, and mind-set called MS Ce issues the call progress message after the expansion in the CRBT.
Here, Event information field=7, the indication calling terminal need switch CRBT, interrupts the signatory CRBT of terminal called.
Step 405, CRBT center stop to play the signatory CRBT of terminal called, and send release message for called MS Ce.
Step 406, called MS Ce receive the call progress message after the expansion that the CRBT center issues, and the call progress message of transparent transmission after should expansion is given caller MSCe.
Step 407, caller MSCe receive the call progress message after the expansion that the CRBT center issues, and after parsing the information that indication terminal called CRBT interrupts, know the CRBT that need switch to calling terminal; Caller MSCe judges whether calling terminal opens Ring Back Tone service, if then execution in step 408; Otherwise, execution in step 410.
The signatory multimedia bell information of step 408, caller MSCe authentication calling terminal, authentication success back sends initial address message to the CRBT center, the signatory CRBT of indication CRBT center playing and calling terminal.
Here, be packaged with the number of calling terminal in the initial address message.
The signatory CRBT of step 409, CRBT center playing and calling terminal sends ALERTING message for caller MSCe; Execution in step 411.
The not signatory CRBT of the signatory multimedia bell information of step 410, caller MSCe authentication calling terminal, calling terminal causes failed authentication, and the MSCe indicating media gateway is play common ring-back tone to calling terminal.
Step 411, the current CRBT switching flow of end.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
