Abstract: A method, system and device for call switching between a mobile device using a mobile communication network and any data communication equipment using other type of communication network without any disconnection of a on ongoing call is provided. In a method for a call switching service, the first and second mobile devices establish wireless communication channels with the mobile communication network, respectively. The first mobile device transfers a call to specific data communication equipment. The mobile communication network establishes a call channel between the specific data communication equipment to which the call is transferred and the second mobile device that is not transferring the call to the specific data communication equipment.
