Table 1
In step 310, the prefix of calling side MSC before according to called number with call proceeding to CRBT AIP.
In step 311, CRBT AIP peels off the prefix of called number, with call proceeding to switching MSC, the number difference different MS C that can transfer.After peeling off the prefix of called number, number is the short code of expression extension.
In step 312, switching MSC arrives the callee with call proceeding.Wherein, if called be the mobile subscriber, then to take the roaming number at family, and return ACM (address is complete) message.ACM message is represented: all essential address informations (numbers of calling and called parties) receive all that oneself send ring-back tone to callee's ring to the calling party.
In step 313, CRBT AIP judges whether the User Status in the ACM signaling is idle, if be idle, then curbs the ring-back tone (CRBT that comprises normal fluid sound and extension subscriber) that the callee is put, the bell sound of playing back group color ring.If called subscriber condition is for conversing, then CRBT AIP points out the callee to converse or plays busy tone to the calling party.
In step 314, when callee's user answer, switching MSC returns ANM (replying) message to CRBT AIP.The ANM indication: the own off-hook of called subscriber, both sides will enter talking state.
In step 315, after CRBT AIP receives the ANM response message, stop the bell sound of playing back group color ring, the caller, called party enters talking state.
In step 316, behind end of conversation, callee's switch sends REL (release) message to CRBT AIP and discharges speech channel message.
In step 317, CRBT AIP sends REL to calling side MSC and discharges speech channel message.
In step 318, calling side MSC sends ACR to SCP and reports charging report.
In step 319, calling side MSC sends ERB to SCP and reports the BCSM event report, and whether report mistakes such as for example on-hook, no response, route selection failure incident occurred.
In step 320, calling side MSC sends RC message to SCP and discharges speech channel message.
In step 321, calling side MSC sends RLC (release is finished) message to CRBT AIP and disconnects speech channel.
In step 322, CRBT AIP sends RLC message to switching MSC and disconnects speech channel.
Though the invention discloses the foregoing description; but specific embodiment be not be used for limiting of the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; can make some modifications and retouching, so protection scope of the present invention should be as the criterion with the scope that appending claims defines.
