Abstract
An incoming call alert system for use with a portable communication device is disclosed as including an accessory unit physically separate from the portable communication device for providing an alerting signal, a wireless link between the portable communication device and the accessory unit, and circuitry electrically connected to operating circuitry of the portable communication device for providing a message exclusively to the accessory unit over the wireless link when an incoming call is received by the portable communication device, the message causing the accessory unit to activate the alerting signal. The circuitry further includes an interface for maintaining and terminating the electrical connection between the circuitry and the operating circuitry of the portable communication device, a transceiver for transmitting messages exclusively to and receiving messages exclusively from the accessory unit over the wireless link, and control logic for monitoring receipt of an incoming call by the portable communication device and activating the transceiver to transmit the message in response thereto. The accessory unit further includes a power source, a transceiver for receiving messages exclusively from and transmitting messages exclusively to the circuitry over the wireless link, a transducer which provides the alerting signal upon activation, and control circuitry for activating the transducer upon receipt of the message by the receiver via the wireless link.
