Wireless user interface extension
First Claim
1. A method of extending a user interface of a mobile communication device by means of a user interface extension device which is configured for vehicle use, the mobile communication device and the user interface extension device communicating over a wireless link, the method comprising the steps of:
- storing, accessible to the user interface extension device, trusted relationship information for connecting to the mobile communication device over the wireless link;
obtaining an authorisation code to use a vehicle;
obtaining an identifier having a common source as the authorisation code;
identifying by the identifier a particular mobile communication device; and
using the identifier to establish the wireless link between the user interface extension device and a particular mobile communication device.

Abstract
A car hands-free unit (HFU 140) with a Low-Power Radio-Frequency (LPRF) module 141 (typically a Bluetooth module) configured to receive an identifier 134 from a car key 133. Different drivers are provided with different car keys 133. When receiving the identifier 134 first time, the HFU stores trusted data to pair with a driver'"'"'s phone. Thereafter, the HFU automatically connects to the driver'"'"'s phone when the same car key 133 is used. The hands-free unit typically comprises a microphone and a loudspeaker, and can also have a display and/or a camera. In operation the HFU provides automatic link 160 with a compliant LPRF enabled mobile phone without need to touch the mobile phone, allowing its use even when the mobile phone is placed in a boot of a car 101.
