Patent ID: 7593749

Claim:
A radio terminal equipment arrangement comprising: a cellular core unit comprising: a control unit for controlling the functions of the cellular core unit, the control unit being configured to communicate with a cellular network using a cellular connection, and to receive an incoming connection request from the cellular network; and peripheral units being configured to communicate with the cellular core unit using a wireless low power radio frequency (LPRF) connection, wherein: the control unit of the cellular core unit is configured to indicate the incoming connection request in one or more peripheral units but not in the cellular core unit, when the LPRF connection between the cellular core unit and a peripheral unit is available; the control unit of the cellular core unit is further configured to indicate the incoming connection request in the cellular core unit when the LPRF connection between the cellular core unit and the peripheral unit is not available, and to indicate the incoming connection request in the peripheral unit, when the LPRF connection between the cellular core unit and the peripheral unit becomes available; and the control unit of the cellular core unit is further configured to establish an incoming connection to the peripheral unit in which the incoming connection request has been accepted, to receive a connection request from another peripheral unit than the peripheral unit to which the incoming connection has been established, to indicate in the other peripheral unit about transferring the connection to the other peripheral unit, and to transfer the established incoming connection from the peripheral unit to which the incoming connection has already been established to the other peripheral unit that has requested the connection.
