8. HLR requests called user roaming number MSRNb (Mobile subscriber roaming number) from called end office;
9. the called terminal office returns a roaming number MSRNb to the HLR;
10. HLR returns roaming number MSRNb to SCP;
11. SCP sends connection request to MSC/SSP of calling visit place, wherein called number is changed to 'prefix + MSRNb'. The prefix implies routing information for the home IP. In addition, the connection information also includes the mobile Station international ISDN number msisdnb (mobile Station international ISDN number) of the MSb.
12. The calling visited place MSC/SSP determines the route to the IP of the intelligent peripheral according to the prefix + MSRNb, and sends an initial address full message IAM to the intelligent peripheral, wherein the message comprises MSRNb and MSSDNb;
13. the intelligent peripheral IP (Intelligent peripheral) obtains the ring back tone information of the MSb currently activated according to the MSISDNB; meanwhile, the intelligent peripheral determines the routing information to a called end office Mobile Switching center/visitor Location Register (MSC/VLR) according to the MSRNb and sends an IAM message to the called end office, wherein the called number is the MSRNb;
14. called end office paging/positioning MSb;
15. MSb responds to page correctly;
16. the called terminal office returns an address full message ACM to the called home intelligent peripheral;

The service control point module interacts with the management module and is used for forwarding the execution request of the service control point to the management module and returning the request execution result of the management module to the service control point. The execution request can be a corresponding relation between certain user information and a ring back tone or download the ring back tone content to a designated intelligent peripheral, can also be a query request for determining whether the visited intelligent peripheral has the corresponding ring back tone and the user information, and can also be an intelligent peripheral for confirming an optimal intelligent peripheral to return to the SCP or returning to the intelligent peripheral meeting the conditions for selection by the SCP according to the location of a called user provided by the SCP. The management module is connected with the intelligent peripheral interface module and is used for distributing information related to the ring tone, such as relationship information between the subscriber number and the ring back tone or ring back tone resource information.
The invention selects the intelligent peripheral after SCP receives the calling request of the roaming user with ring back tone service as the called, then routes the calling to the selected intelligent peripheral, and the intelligent peripheral switches the speech path to play the ring back tone to the calling user.
Certainly, the intelligent peripheral has more selection modes, such as according to whether the intelligent peripheral is nearest to the called visited MSC/VLR, the idle state of the intelligent peripheral, whether the intelligent peripheral has corresponding data of the called party and the ring tone, and the like. Of course, combinations of the above conditions are also possible. The preferred mode is to select the proper ring tone playing device to provide the ring tone service for the call according to the nearby principle according to the positions of the called visiting mobile switching center/visiting location register and the ring tone playing device.
After receiving the ring back tone service call request, the SCP can locate the location of the called subscriber by interacting with the home HLR of the called subscriber, which may specifically include the following steps: SCP inquires MSb state to HLR; HLR returns MSb state; SCP requests the called route information from HLR, and restrains the pick-up contract information; HLR requests roaming number to visit MSC/VLR; MSC/VLR returns roaming number MSRNb to HLR; the HLR returns routing information to SCP, which contains roaming number MSRNb.
After the SCP determines the position of the called user according to the roaming number of the called user, the SCP sends a query request to the ring back tone service system, the ring back tone service system determines an optimal intelligent peripheral according to the stored basic information of the intelligent peripheral, the related information of the intelligent peripheral is returned to the SCP, or the information of the intelligent peripheral meeting the conditions is returned to the SCP, and the SCP selects the optimal intelligent peripheral. After selecting and determining a certain intelligent peripheral, SCP sends connection to MSC/SSP of calling visit place, prefix is added in front of roaming number MSRNb to guide call to route to the selected intelligent peripheral.
The ring back tone service system may distribute the ring tone of the called subscriber and the subscriber data to the intelligent peripheral equipment of the visited place according to the execution request of the SCP, as shown in fig. 4, specifically including the following steps:
1. SCP requests ring back tone service system to send ring back tone and user data to intelligent peripheral while sending connection;
2. the ring back tone service system sends ring back tone and user data to the intelligent peripheral; certainly, because the ring tone resources are managed uniformly, a certain ring tone may exist in the intelligent peripheral device, but there is no user data, and in this case, the ring back tone service system only needs to issue the user data, that is, the relationship data between the user and the ring tone, to the intelligent peripheral device.
3. The intelligent peripheral registers user data and/or loads ring tone resources;
4. the intelligent peripheral returns a ring tone distribution response;
5. the ring back tone service system updates system data and marks the existing user data and ring back tone resources of the intelligent peripheral;
6. the ring back tone service system returns a ring back tone distribution response to the SCP;
7. and the SCP updates system data and marks the existing user data and ring tone resources of the intelligent peripheral.
Of course, the ring back tone service system can also actively send the ring back tone of the called subscriber and the subscriber data to a certain intelligent peripheral according to the using frequency of a certain ring back tone of the called subscriber near the intelligent peripheral.
In yet another embodiment of the present invention, the SCP, upon receiving the ringback tone service call request, interacts with the HLR to which the called subscriber belongs to locate the location of the called subscriber, namely, the called visiting MSC/VLR is determined, an optimal visiting place intelligent peripheral is determined according to the basic information of the intelligent peripheral stored in the ring back tone service system, such as the intelligent peripheral device nearest and available to the called subscriber's visited MSC/VLR, and checks the ring tone resources and subscriber information associated with the intelligent peripheral device, if the intelligent peripheral does not have the corresponding ring tone and/or the corresponding relation data of the called user and the ring tone, the SCP decides to complete the ringback tone service also temporarily by the called home intelligent peripheral, considering that the impact on the call is minimized, at the same time, SCP requests the ring back tone service system to distribute or load ring tone (if it has already, it does not load) and user data to the intelligent peripheral equipment of visiting place. Of course, if the ring tone is set on the intelligent peripheral of the visiting place, only the corresponding relation information between the ring tone and the user is issued. After the ring tone distribution is completed, the SCP can update the system data and mark the existing user data and ring tone resources of the intelligent peripheral equipment at the visiting place. Thus, when the called user is called next time, the SCP can appoint the intelligent peripheral equipment of the called visiting place to provide the ring back tone service as long as the called user is still at the place.
