Description

System and method for obtaining a called intelligent service or routing number

technical field

The present invention relates to the technical field of communication, more specifically, to a system and method for obtaining a called intelligent service or routing number.

Background technique

In softswitch technology, mixed number allocation and intelligent services for fixed users have been widely used in telecommunication networks, generally through softswitch (SOFTSWITCH), smart home location register (Smart Home Location Register, abbreviated as SHLR) and Service Control Point (Service Control Point, abbreviated as SCP) to achieve. The softswitch sends the routing number of the calling user and the logical number of the called user to SHLR according to the Mobile Application Part (MAP for short), and the SHLR returns the logical number of the calling user and the routing number of the called user to SOFTSWITCH. When the user registers the smart service, SHLR also needs to return the smart service access code of the calling and called user to SOFTSWITCH, and SOFTSWITCH moves the call up to the SCP according to the smart service access code to realize the smart service registered by the user. If the calling user has completed the triggering of the calling intelligent service before SOFTSWITCH sends the Send Routing Information (SRI) to the SHLR, the above implementation method will lead to repeated triggering of the calling user's intelligent service. When the existing SHLR queries the routing number of the called user, it does not consider the calling number in the query message, but simply returns the routing number registered by the called user, but in some cases, the called routing number Needs to be associated with the calling user. For example, for special service services (such as business and industry complaint telephone numbers, which are used as a special service number and require to be connected to the business service center in the corresponding area according to the area of the calling user), SHLR needs to return different called numbers for calling users in different areas. Routing number so that SOFTSWITCH completes the connection of the call to a different called party.

At present, a technical solution for querying the called routing number and intelligent services has been proposed. The message interaction process is shown in Figure 1. When SOFTSWITCH sends the query message SRI to SHLR, it does not send the calling party number or sends a nonexistent calling party number. Call the user number, such as "00000000", SHLR can not get the intelligent service of the calling user according to the calling number in the database, but can only query the intelligent service or the called routing number of the called user, thus solving the problem of avoiding repeated triggering of calling User's smart business. However, since there is no calling number or the calling number is an invalid number in this technical solution, this solution cannot realize the function of obtaining different called routing numbers through different calling numbers for the same called logical number. The called user needs to locate the called user's routing service according to the calling user's physical location, such as the business special service service, etc., the routing number of the called user cannot be obtained, and SOFTSWITCH cannot connect the called party to a different special service In the number, these services cannot be applied.
