The independent smart peripherals are in the bridge state during the call.

In Fig. 2, when the calling user initiates a call to the MSC/SSP at the sending end, the MSC/SSP at the sending end sends a Query Routing Information (SRI) message to the HLR of the called user to obtain the smart subscription information T-CSI of the called user, which The information includes whether the called user has customized the personalized ring back tone service. After obtaining the T-CSI information of the called user, the MSC/SSP at the sending end triggers the called process to the SCP of the called user. The MSC/SSP at the sending end sends an Initiate Detection Point (IDP) message to the home SCP, and the home SCP sends an SRI message to the HLR of the called user to obtain the roaming number and current status of the called user. If the current state of the called user is busy or cannot be paged, the home SCP sends a connection instruction to the MSC/SSP at the sending end, and the MSC/SSP at the sending end connects the call to the MSC/SSP at the receiving end, and the MSC/SSP at the receiving end Send a recording notification to the calling party. If the current state of the called user is idle, the home SCP sends a connection confirmation message ACM, a request to report BCSM event RRBE message, and a connection CONNECT message to the sending end MSC/SSP, and the roaming number of the called user is prefixed to the CONNECT message. The route prefix is added as the called number, and the real number called, that is, the mobile phone number MSISDN of the called user is also sent together in the CONNECT message. After receiving the above message, the MSC/SSP at the sending end routes the call to an independent intelligent peripheral according to the routing prefix of the called number, and sends an initial address message IAM to the intelligent peripheral. The called number included in the IAM is with The roaming number of the called user in the routing prefix. The original called number is the mobile phone number of the called user. After the independent intelligent peripheral device receives the connection request message, it removes the routing prefix of the called number, and connects to the receiving end MSC/SSP according to the normal IAM message. After the MSC/SSP at the receiving end finds the called user, it returns the address complete message ACM to the smart peripheral. If the ring tone is not customized, the ringback tone sent from the receiving end MSC/SSP will be sent to the calling user; if it is customized, it will be based on the value of the cause indicator in the ACM message and the mobile phone number of the calling user Combined with the mobile phone number of the called user to determine the ring-back tone customized by the called user, play the ring-back tone to the calling user, and block the ring-back tone sent from the receiving end MSC/SSP. After the called user picks up the phone to answer, the intelligent peripheral device receives the response message ANM sent by the MSC/SSP at the receiving end, stops playing the ringback tone, sends ANM to the MSC/SSP at the sending end, establishes a call, and starts talking.

Users can apply for personalized ring back tone services through relevant websites, voice interaction, business halls, WAP, short messages, etc., and customize personalized ring back tones through WWW, WAP, short messages, and dialing corresponding access codes, etc. , when it is the called user, it plays a customized ring-back tone for the calling user according to different calling numbers, the status of the called user and other conditions, instead of the ordinary ring-back tone.
