Converged communication service implementation method and system

The invention discloses a converged communication service implementation method and system. The method comprises the following steps of: binding a key of a U-Key disk and a mobile phone number of a service mobile phone through a service registration server by the service mobile phone, generating first binding information, storing the first binding information in the service registration server, and generating called subscription information at a home location register (HLR); when an intelligent dialing terminal connected with a service fixed phone detects that the U-Key disk is inserted, sending a converged vibration activation request to the service registration server, wherein the converged vibration activation request carries the key of the U-Key disk; acquiring the mobile phone number bound with the key, and sending a converged vibration activation instruction to service processing center equipment, wherein the converged vibration activation instruction carries the fixed phone number and the mobile phone number; generating second binding information, and storing the second binding information in the service processing center equipment; and performing converged vibration and simultaneous response together with the service mobile phone according to the called subscription information and the second binding information by the service fixed phone. The method and the system disclosed by the invention realize automatic transaction of the converged communication service.
