Abstract:
1. System for secure linking and delinking of a secondary peripheral unit for a common wireless interface unit comprising: a first peripheral unit and an interface unit, wherein the first peripheral unit comprises a microphone and a speaker, and the first peripheral unit is connectable to a telephone via the interface unit, the interface unit having a unique interface unit device address, and the first peripheral unit having a unique peripheral unit device address, wherein the first peripheral unit and the interface unit are mutually connectable via a primary wireless communication link for audio communication, and wherein the system further comprises pairing routine for pairing the first peripheral unit and the interface unit to establish the primary wireless communication link, and wherein the first peripheral unit and the interface unit are mutually connectable via a detachable wired communication link for auxiliary data, and that the pairing routine are automatic, the automatic pairing routine comprising: a link detection routine for detecting an established wired communication link between the first peripheral unit and the interface unit, address exchange routine adapted to exchange the first peripheral unit device address and/or the interface unit device address via the wired communication link between the first peripheral unit and the interface unit when said link has been established, and a static personal identification number (PIN) for use during pairing, the PIN being shared between the interface unit and the first peripheral unit, the system further comprising a secondary peripheral unit in addition to the first peripheral unit, the first peripheral unit being the primary peripheral unit, wherein the secondary peripheral unit comprises a microphone and a speaker, and the secondary peripheral unit is connectable to the telephone via the interface unit, the secondary peripheral unit having a unique device address, wherein the secondary peripheral unit and the interface unit are connectable both via a secondary wireless communication link for audio communication and via a wired communication link for auxiliary data, the wired communication link being detachable, and wherein the interface unit is adapted to be simultaneously wirelessly connectable to both the primary peripheral unit and the secondary peripheral unit by the primary wireless communication link and the secondary wireless communication link, and wherein the automatic pairing routine is further adapted for pairing the secondary peripheral unit and the interface unit to establish the secondary wireless communication link by a secondary pairing, the link detection being adapted to detect the state of the primary and secondary wired communication link, the address exchange routine being adapted to exchange the unique device addresses via the secondary wired link, and the static personal identification number (PIN) being shared between the interface unit and the primary and secondary peripheral units for use also during the secondary pairing wherein the wireless communication link transmits calls to the primary and secondary peripheral units during a call but that the secondary wireless communication link expires after one active call, so that the user of the second peripheral unit cannot eavesdrop on subsequent calls via said link.
