A method, service control device and communication system for realizing the service of one card for multiple numbers

摘要

A method for implementing the one card multinumber service includes: (i) associating one master number of a user with a slave number of a different home location; and (ii) determining the user number to be displayed at the peer side or routing the service to the master number of the user according to the correspondence between the master number and the slave number. When the one card multinumber user makes a call, the SCP selects a number as a calling number for display among the master number and the associated slave number according to a preset policy. When the one card multinumber user is called, no matter whether the called number is the master number or the slave number, the SCP instructs the originating MSC to route the call to the master number of the one card multinumber user according to the correspondence between the master number and the slave number. The invention facilitates the user in using the service, and reduces communication costs of the user.
