A method for uniform number communication on a home gateway, implemented by the home gateway, in a system including the home gateway, terminals connected to an interface of the home gateway and a network apparatus in charge of scheduling connections to terminal numbers of the terminals, the method comprising: a) binding terminal numbers of terminals connected to an interface of the home gateway to a uniform number, and configuring a binding relation for the bound terminal numbers; and b) sending a uniform number binding message carrying the uniform number and the binding relation to the network apparatus; c) wherein the terminal numbers are PSTN number, VoIP number and mobile phone number, d) the binding relation includes the bound terminal numbers and an incoming call priority of the bound terminal numbers indicating that when a terminal under the uniform number is busy when the uniform number is called, connections to the bound terminal numbers are to be established in turn according to the priority; wherein e) after sending the uniform number binding message carrying the uniform number and the binding relation, the method further comprises: e1) updating the terminal numbers of terminals connected to the interface of the home gateway when the terminals connected to the interface of the home gateway are changed; e2) binding updated terminal numbers to the uniform number, and reconfiguring a binding relation for the updated bound terminal numbers, wherein the reconfigured binding relation includes the updated bound terminal numbers and the incoming call priority of the updated bound terminal numbers; and e3) sending a uniform number binding message which carries the uniform number and the reconfigured binding relation to the network apparatus. a) binding terminal numbers of terminals connected to an interface of the home gateway to a uniform number, and configuring a binding relation for the bound terminal numbers; and b) sending a uniform number binding message carrying the uniform number and the binding relation to the network apparatus; c) wherein the terminal numbers are PSTN number, VoIP number and mobile phone number, d) the binding relation includes the bound terminal numbers and an incoming call priority of the bound terminal numbers indicating that when a terminal under the uniform number is busy when the uniform number is called, connections to the bound terminal numbers are to be established in turn according to the priority; wherein e) after sending the uniform number binding message carrying the uniform number and the binding relation, the method further comprises: e1) updating the terminal numbers of terminals connected to the interface of the home gateway when the terminals connected to the interface of the home gateway are changed; e2) binding updated terminal numbers to the uniform number, and reconfiguring a binding relation for the updated bound terminal numbers, wherein the reconfigured binding relation includes the updated bound terminal numbers and the incoming call priority of the updated bound terminal numbers; and e3) sending a uniform number binding message which carries the uniform number and the reconfigured binding relation to the network apparatus. e1) updating the terminal numbers of terminals connected to the interface of the home gateway when the terminals connected to the interface of the home gateway are changed; e2) binding updated terminal numbers to the uniform number, and reconfiguring a binding relation for the updated bound terminal numbers, wherein the reconfigured binding relation includes the updated bound terminal numbers and the incoming call priority of the updated bound terminal numbers; and e3) sending a uniform number binding message which carries the uniform number and the reconfigured binding relation to the network apparatus.
