Problems solved by technology

But PHS numbers are standard fixed-line numbers, so you need to add the province codes to distinguish them.
Moreover, this also brings difficulties to the allocation of operator number resources

Abstract

The invention provides a call method of local number portability service, a system thereof and a mobile switching center (MSC), and relates to the field of mobile communication. The invention aims atsolving the technical problem that the original number of a terminal is needed to be changed when the network of the terminal is transferred in the prior art. The call method of the local number portability service is used for calling a called terminal by a calling terminal, and the calling terminal has local number portability and is transferred into a second network scene from a first network; the method comprises: the MSC of a second network can acquire individual user number of the second network of the calling terminal from the calling terminal; the MSC of the second network searches individual user number of the first network corresponding to the individual user number of the second network of the calling terminal from a number portability data base (NPDB); and the individual user number of the first network is sent to the MSC of the called terminal by the MSC of the second network. The invention can be used for the local number portability service of a personal hand-phone system.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a call method, system and mobile switching center MSC for number portability transfer service. Background technique [0002] With the development of communication technology, PHS (Personal Handy Phone System, PHS) will gradually withdraw from the stage of history, that is to say, all PHS operators have to complete the work of PHS frequency clearing and network withdrawal. [0003] At present, the plans for PHS users to switch to the network include: upgrade and transfer with guaranteed number, that is, add digits before the original number to form a new mobile phone number segment, and the last 7 (or 8) digits are consistent with the original PHS number, such as 189*+( original PHS number). This scheme has little change to the original number of PHS, and it is convenient for users to maintain communication through the original PHS number. However, PHS numbers are standard fi...
