A mobile telephone 12 acts as a radio communications gateway between a 3G network 10 and a Bluetooth.RTM. network 11. A video conference call in the 3G network 10 is relayed over the Bluetooth.RTM. network 11 to and from a Bluetooth.RTM. enabled laptop Personal Computer (PC) 13, which therefore acts as a radio communications terminal. A Channel Quality Indicator (CQI) received by the mobile terminal 12 with the video conference content over the 3G network 10 is transmitted by the mobile telephone 12 to the laptop PC 13 over the Bluetooth.RTM. network 13 as a Pseudo-CQI (P-CQI). In this example, the P-CQI is sent in a FLOW control field of a header 40 of a Synchronous Connection Oriented (SCO) or extended SCO (eSCO) data packet of the Bluetooth.RTM. network 11. A video conference driver application running on the laptop PC 13 is then able to alter the video conference call properties according to the value of the P-CQI, thus responding to call quality conditions in the 3G network 10.
