Vehicle telecommunication apparatus with RF antenna switching arrangement
First Claim
1. A mobile vehicle telecommunication system for use in the provision of mobile application services to the vehicle from a remote location over a telecommunications network, the telecommunication system comprising, in combination:
- an embedded transceiver on the vehicle;
an embedded antenna on the vehicle;
an embedded radio frequency terminal on the vehicle;
a portable transceiver having an integrated antenna and an external radio frequency terminal removably connected to the embedded radio frequency terminal in the vehicle;
electrically controlled radio frequency switch means having an activated condition connecting the embedded antenna to the embedded radio frequency terminal and an inactivated condition connecting the embedded antenna to the embedded transceiver and disconnecting the embedded antenna from the embedded radio frequency terminal;
means for coupling a received radio frequency signal from the embedded antenna to the embedded transceiver when the electrically controlled radio frequency switch means is in its activated condition;
means responsive to a radio frequency signal generated by the embedded transceiver for switching the electrically activated radio frequency switch means to its inactivated condition.

Abstract
Vehicle telecommunication apparatus permits sharing of an embedded antenna between an embedded transceiver used for the provision of mobile application services to the vehicle and a portable transceiver used for personal communication by the vehicle operator. Closure of a mobile vehicle use switch, such as a vehicle ignition switch, with the portable transceiver connected to an embedded RF terminal, places an electrically controlled RF switch in an activated condition providing a through connection between the portable transceiver and embedded antenna for transmission and reception and a coupled connection from the embedded antenna for reception by the embedded transceiver. A generated RF signal from the embedded transceiver is coupled to a detector to switch the electrically controlled RF switch to its inactivated condition, in which the portable transceiver is disconnected from the embedded antenna and a through signal path is established between the embedded transceiver and embedded antenna. The inactivated condition of the electrically controlled RF switch is also produced its own failure, by opening the mobile vehicle use switch or by disconnecting the portable transceiver. The antenna sharing provides better reception and transmission in the use of the portable transceiver for calls from the vehicle while allowing the portable transceiver to be removed from the vehicle by the operator for use outside the vehicle with the embedded antenna connected to the embedded transceiver for receipt of mobile application services from a service center.
