Method, device and system for processing number portability

Abstract

The embodiment of the invention provides a method, device and system for processing number portability. The method comprises the following steps: receiving a service request message containing a first call number and transmitted by mobile switching equipment; confirming the first call number to be a short number; normalizing the short number of the first call number into a long number; acquiring number portability information corresponding to the long number of the normalized first call number from a number portability database according to the long number of the normalized first call number; and transmitting a call connection request to the mobile switching equipment according to the number portability information. When the first call number is the short number, the method, the device and the system which are provided by the embodiment of the invention can ensure the first call number can be normalized from the short number to the long number, the number portability information corresponding to the first call number can be acquired according to the long number, thus the number portability information of a number can be correctly acquired when a user dials in various forms, and the normal charging or normal routing of the telecommunication service is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a number portability processing method, device and system. Background technique [0002] With the development of telecommunication services, various operators provide users with more and more diversified services, and users can choose among various operators according to their own needs. When the user communicates, the service control point (Service Control Point, hereinafter referred to as: SCP) needs to obtain the information of the operator to which the telephone number belongs through the number range information table of the phone number; however, the number range information table is provided by the operator. Self-maintained, when the user changes the operator, that is, when the phone number used by the user is transferred to the network, neither the original operator nor the current operator of the phone number can maintain the number...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the NP information stored in the existing NP database is corresponding to the complete telephone number, wherein the complete telephone number is an integrated service digital network (Integrated Services Digital Network, abbreviated as: ISDN) number, the STP can only query according to the complete phone number in the IDP message; however, in the intelligent network service, when the phone number dialed by the user is an incomplete phone number, for example : In the virtual private network (Virtual Private Net, hereinafter referred to as: VPN) business, the user will dial a short number, then the STP will not be able to query the accurate NP information of the phone number, thus it will not be able to accurately obtain the operator to which the phone number belongs If the operator information and network transfer information are not used, it will cause errors in telecom service billing or routing failures.
