Abstract: An in-vehicle handsfree apparatus performs a dialing control with a first dialing phone number, which is a phone number included in historical data of outgoing or incoming calls of a cellular phone. If the destination of the dialing with the first phone number does not answer, the handsfree apparatus performs a dialing control by using a different second phone number, if it is available from the cellular phone. The second phone number, e.g., a number of a home telephone, is registered in phone book data of the cellular phone by using the same registration name as that of the first phone number; further, the second phone number is transmitted from the cellular phone to the handsfree apparatus.

Abstract: Circuits, architectures, systems, methods, algorithms, and software and/or firmware for arbitrating media access requests from multiple wireless communication protocol components. Exemplary circuits include a request processing circuit configured to set a positive media access grant output for a first one of the wireless component before entering a power saving mode of operation, determine a waking media access state of the first wireless component while exiting the power saving mode of operation, and process media access requests from the wireless components the waking media access state of the first wireless component. Embodiments of present invention advantageously provide for more reliable arbitration of media access requests from multiple wireless communication protocol components during and after power saving modes of operation.
