Problems solved by technology

However, since all calls to the different network will be queried by the NP database, when the NP database fails, all calls to the different network will not be completed due to 5% of the user data, resulting in large-scale network communication failures
If there is no corresponding protection mechanism, the implementation of NP services will be affected, thereby affecting the safe operation of the entire network

Embodiment Construction

[0023] The invention will be described in more detail hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. In the drawings, the same reference numerals denote the same or similar components or elements.

[0024] figure 1 It is a schematic diagram of an application scenario 100 according to an embodiment of the present invention. The application scenario 100 includes a calling terminal 102 , a called terminal 112 , a mobile gateway office 104 in a local network, a mobile gateway office 114 in a different network, and an NP database 106 .

[0025] Both the local network mobile gateway office 104 and the inter-network mobile gateway office 114 can perform switching, mobility management, routing and call control functions, and billing, etc., and realize intercommunication with the fixed network. The local network mobile gateway office 104 and the inter-network mobile gateway office 114 may be GMSC (Gateway Mobi...

Abstract

The invention provides a calling control method and a device and relates to the technical field of mobile communication application. The calling control method for a number portability service comprises the steps of: sending a request for inquiring NP data of a called terminal to a NP database through a mobile gateway according to a received calling request, starting a bypass module through the mobile gateway when the mobile gateway judges that the NP database inquiry is invalided, judging the original affiliated network of the called terminal by the bypass module according to the number of the called terminal, and sending the number and the route code of the called terminal to the mobile gateway corresponding to the original affiliated network of the called terminal by the bypass module according to the original affiliated network of the called terminal, wherein the route code is the route code corresponding to the original affiliated network of the called terminal. The method of theinvention efficiently solves the problem of internet communication failure caused by the centralized set NP database.

Description

technical field [0001] The present invention relates to the technical field of mobile communication applications, in particular to a call control method and device. Background technique [0002] In the existing NP (Number Portability, Number Portability) scheme stipulated by the Ministry of Industry and Information Technology, in order to realize number portability, all calls to different networks need to increase the process of querying the NPDB (Number Portability Data Base, Number Portability Database). According to the query result, it returns whether the number has been ported to another network. If number portability occurs (from another network to this network), then add the routing code (RN) of this network, and continue to complete the call on this network; if no number portability occurs, then add the routing code of the different network, Route to the other party's network. [0003] As for the networking of the NP database and the problems caused by it, the Mini...
