Description
Technical field
The present invention relates to communication technical field, more specifically, relate to the system and method that is used to obtain called intelligent service or routing number.
Background technology
In Softswitch technology, the fixed-line subscriber mixing is distributed telephone numbers and IN service is now applied in the communication network widely, it generally is by SoftSwitch (SOFTSWITCH), Smart Home Location Register (Smart Home Location Register, be abbreviated as SHLR) and service control point (Service Control Point is abbreviated as SCP) incompatible realization matches.SoftSwitch is according to MAP (Mobile Application Part, be abbreviated as MAP) send calling subscriber's routing number and called logical number to SHLR, SHLR returns the logical number of caller and called routing number to SOFTSWITCH, if the calling and called user has registered IN service, SHLR also needs to return calling and called user intelligent service access code and gives SOFTSWITCH, and SOFTSWITCH will call out according to this IN service access code and move to the IN service that SCP realizes that the user registers.If the calling subscriber will send routing iinformation (Send Routing Information at SOFTSWITCH, be abbreviated as SRI) be sent to the triggering that SHLR has finished the intelligent dialing business before, above-mentioned implementation method will cause repeated trigger calling subscriber's IN service.Existing SHLR not will consider the calling number in the query messages, and the routing number of just simply the called subscriber being registered returns, but in some cases, called routing number need be relevant with the calling subscriber when inquiry called subscriber's routing number.For example, special clothes are professional (as industrial and commercial phone call for appeal number, this number is as a special service number, requirement is routed to the industrial and commercial service centre of corresponding area by calling subscriber's zone), SHLR need return different called routing numbers at the different regions calling subscriber, so that SOFTSWITCH finishes call proceeding to different called subscribers.
A kind of technical scheme of inquiring about called routing number and IN service has been proposed at present, its message interaction process as shown in Figure 1, when SOFTSWITCH sends query messages SRI to SHLR, do not send rear subscriber number or send a non-existent rear subscriber number, for example " 00000000 ", SHLR can't obtain calling subscriber's IN service according to calling number in database, can only inquire called subscriber's IN service or called routing number, thereby solve the IN service of avoiding the repeated trigger calling subscriber.But, because not having calling number or calling number in this technical scheme is invalid number, therefore, this scheme can't realize at identical called logical number, obtain the function of different called routing numbers by different calling numbers, need locate in the business of called subscriber's route according to calling subscriber's physical location some called subscribers, for example industrial and commercial special clothes business etc., can't obtain called subscriber's routing number, SOFTSWITCH also just can't cause these business to use with called connection in different special service numbers.
Summary of the invention
