In sum, the present invention is based on the in real time synchronous thought of operator's local data base and central database, proposed a kind of universal method and system that realizes number portability service.
The calling of carrying for a number, complicated situation relates to three carrier networks, and these three carrier networks are respectively to open to exhale before network (Originating Network), the telephone-moving network (Recipient Network) behind the network (Donor Network) and telephone-moving.
Method according to the realization number portability service of the embodiment of the invention mainly may further comprise the steps:
Step 1, build the shared number of concentrating of each operator of cover and carry management of information and Query Database system (Centralized Number Portability AdministrationCenter), this system comprises telephone-moving ADMINISTRATION SUBSYSTEM (Port Management System) and inquiry response subsystem (Query Response System).The maintenance that the telephone-moving ADMINISTRATION SUBSYSTEM is mainly finished request processing that number carries and number carries information, inquiry response subsystem are mainly finished number and are carried the inquiry of information and synchronously.These two subsystems of telephone-moving ADMINISTRATION SUBSYSTEM and inquiry response subsystem are separate comparatively speaking.The telephone-moving ADMINISTRATION SUBSYSTEM is finished number and is carried processing of request, comprises two-part interface function: with the Processing Interface function of operator and the interface function of inquiry response subsystem.Be divided into Human-to-Machine's (Human to Machine) interface and machine to machine (Machine toMachine) interface with the Processing Interface function of operator.The inquiry response subsystem is mainly finished the data in the Query Database quasi real time is synchronized to function in operator's local search database, and provide corresponding graphical user interface (Graphical User Interface is called for short GUI) interface to realize operator or user's information inquiry.
Step 2, each operator carries out number portability service according to the service needed of oneself, the number portability service of each operator all uses the local search database (LocalQuery Database) of oneself, all relevant numbers carry the inquiry of information and just finish at local data base, do not need to carry inquiry in management of information and the Query Database system to the number of concentrating.Each operator builds and safeguards the number portability service of oneself separately and sets up the local data base of oneself.Like this, relevant number carries to call out only needs the database of inquiry operator this locality to get final product, and do not need again to inquiring about relevant number during the number of concentrating that each operator shares carries management of information and Query Database system to carry information, this has just effectively alleviated the inquiry burden that the number of concentrating carries management of information and Query Database system, has also satisfied each operator number of applying in a flexible way simultaneously and has carried the demand of information.There are two kinds of implementations in each operator in the number portability service of carrying out separately, be respectively all Query Database (All Call Query is called for short ACQ) and called feedback back Query Database (Query on Release is called for short QOR) of all-calls.So-called ACQ is exactly from opening the calling of exhaling network (Originating Network) for any one, at first called number is carried out the inquiry that number carries information, if called number is telephone-moving, then with the new number replay call that checks out network (Recipient Network) after the telephone-moving, otherwise also be to use original number to call out.So-called QOR directly calls network (DonorNetwork) before the telephone-moving for any one from opening the calling of exhaling network (Originating Network), if this called number telephone-moving, then open and exhale network (OriginatingNetwork) can receive relevant call failure message, determine the telephone-moving of this number by the failure reason value in the message, then open and exhale network (Originating Network) inquiry local number to carry database, call out network (RecipientNetwork) after the telephone-moving according to Query Result.
Step 3, the number of realize concentrating carries management of information and Query Database system and carries the synchronous of database to the local number of each operator, through this step, each operator just respectively has a concentrated number to carry the data copy of management of information and Query Database system at local data base.Described herein can be the local data base that the inquiry response subsystem initiatively is synchronized to the change part operator synchronously, also can be the local data base of operator initiatively be initiated to the inquiry response subsystem synchronously and query requests.Two kinds of methods of synchronization are applied in different occasions, carry the change of information for independent number, the inquiry response subsystem can initiatively be broadcast to these changes in the local data base of an operator, and for the special synchronization request of certain operator, for example full storehouse copy etc., just need initiate request, finish synchronously by the inquiry response subsystem by operator's local database system.
The implementation of the number portability of cross operator proposed by the invention has been realized the cooperation between each operator well, each operator is as long as be responsible for the database and the number portability service logical process of own network, and do not need to be concerned about the realization that the number of other carrier network carries.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
