Patent ID: 7796512

Claim:
A switching source device for moving a session established with a communication counterpart to a switching destination device, comprising: a service discovery section for obtaining information as to whether a service can be provided from a neighboring communication device; a high speed device switching section for instructing the service discovery section at an arbitrary timing to inquire whether a service can be provided, determining a switching destination candidate device that is a switching destination of a session based on the obtained information as to whether the service can be provided, generating a switching destination candidate device list describing the switching destination candidate devices, and making an instruction for establishing a session with the switching destination candidate device; a signaling section for establishing a session with the switching destination candidate device when the instruction for establishing a session is received from the high speed device switching section and; an input section for receiving a switching destination candidate device list request from a user; and an output section for presenting the switching destination candidate device list when the high speed device switching section receives the switching destination candidate device list request through the input section; wherein when the high speed device switching section receives a device switching request from a user through the input section, it notifies the signaling section of the device selected from the switching candidate device list, and the signaling section sends a switching instruction to the selected device.
