Abstract
A wireless communications device is a hub for a conference call between a user of the device, a first remote party, and a second remote party. The wireless communications device communicates with the first remote party over a first connection and with the second remote party over a second concurrently active connection. A circuit in the wireless communications device transcodes voice data received over the first and second connections so that the voice data may be shared between the parties.
Claims11
A method of establishing a conference call at a wireless communications device, the method comprising:
- establishing a conference call at a wireless communications device operating in a dual transfer mode between the wireless communications device and first and second remote parties, the wireless communications device communicating with the first remote party over a circuit-switched connection and with the second remote party over packet-switched connection;
- and
- receiving, at the wireless communications device, inbound voice data from the first remote party over the circuit-switched connection, and inbound packetized voice data from the second remote party over the packet-switched connection;
- transcoding, at the wireless communications device, the inbound voice data into outbound packetized voice data by:
- mixing the inbound voice data with voice data generated at a microphone of the wireless communications device to generate composite packetized voice data;
- and
- encoding the composite packetized voice data to be transmitted over the packet-switched connection,
- transcoding, at the wireless communications device, the inbound packetized voice data into an outbound voice data by:
- mixing the inbound packetized voice data with voice data generated at the microphone of the wireless communications device to generate composite voice data;
- encoding the composite voice data to be transmitted over the circuit-switched connection;
- and
- transmitting the composite packetized voice data to the second remote party over the packet-switched connection, and transmitting the composite voice data to the first remote party ever the circuit-switched connection.

A wireless communications device comprising:
- a microphone to generate audio signals from audible sound detected at the wireless communications device;
- a controller configured to establish a conference call between the wireless communication device and first and second remote parties, wherein the wireless communications device communicates with the first remote party over a circuit-switched connection and with the second remote party over a concurrently active packet-switched connection;
- a transceiver to receive data from the first remote party over the circuit-switched connection, and the second remote party over the packet-switched connection;
- circuitry configured to transcode inbound voice data received over the circuit-switched connection into packetized voice data for transmission over the packet-switched connection, and transcode inbound packetized voice data received over the packet-switched connection into voice data for transmission over the circuit-switched connection, the circuitry comprising:
- a first mixing circuit to mix the inbound voice data received over the circuit-switched connection with the audio signals to generate a first composite voice signal;
- a first encoder to encode the first composite voice signal into composite packetized voice data to be transmitted over the packet-switched connection;
- a second mixing circuit to mix the inbound packetized voice data received over the packet-switched connection with the audio signals to generate a second composite voice signal;
- and
- a second encoder to encode the second composite voice signal into composite voice data to be transmitted over the circuit-switched connection;
- and
- the transceiver further configured to transmit the composite voice data over the circuit-switched connection to the first remote party, and the composite packetized voice data over the packet-switched connection to the second remote party.
