<p>A method for realizing one number multiple terminals service is provided in the present invention and includes that: a calling terminal calls a called terminal which is in a first network; when the called terminal has subscribed one number multiple terminals service and the called number is a master number, the first network triggers the call service to a smart service platform; the platform obtains and saves a Temporary Local Directory Number (TLDN) of the called terminal corresponding to the master number from the first network and distributes a service control indication to the first network; the first network routes the call to a Next Generation Network (NGN) based on the service control indication distributed by the platform; the Next Generation Network triggers the call service to the platform and the platform returns the Temporary Local Directory Number of the called terminal corresponding to the master number and all the other terminal numbers bound to the master number to the Next Generation Network in order to connect to the called terminals. A system for realizing one number multiple terminals service is also provided in the present invention. With the method and system in the present invention, the simultaneous ring or ordinal ring of multiple user terminals can be realized by using a mobile terminal number as the master number.</p> |
