Abstract: A visual interface for a PTT user terminal displays user images of participants in a PTT conference. When a PTT conference is established, a controller determines whether an image associated with each participant invited to the PTT conference is stored in memory on the user terminal. For each participant that has an associated image stored on the user terminal, the controller displays the image. For those participants that do not have an associated image stored on the user terminal, the controller generates and sends a request for the image. Upon receipt of the image, the controller displays the image on the user terminal. During the PTT conference, the controller alters the appearance of the images to show the status information of each participant, such as which participant has floor control and presence of participants.

Abstract: A method and apparatus for controlling a function of a communication device by a remote unit. The method may comprise receiving a user input identifying a selected function that can be performed by the communication device, and receiving a control signal corresponding to a selected control on the remote unit. The method may further comprise associating the selected function to the control signal such that in the future, receiving the control signal from the remote unit results in the communication device performing the selected function. The device may include a cellular radio transceiver; and a short-range wireless transceiver. The communication device may include a processor configured to communicate with a remote unit and receive user input identifying a selected function, and receive a control signal from the remote unit corresponding to a selected control on the remote unit.

Abstract: Methods of operating radio communications devices may include accepting user input at the radio communications device of a streaming time to initiate media streaming, and accepting user input at the radio communications device of a network address of a streaming server to provide media streaming content. At the streaming time, initiating media streaming from the streaming server identified by the network address may be initiated over a radio link. Related devices are also discussed.

Abstract: A method of estimating initial channel quality in a receiver when allocated a new channel in order to select an optimal codec mode in a multi-rate service is disclosed. One implementation initially fills the filter state with the first received channel quality measurement. Another embodiment proportionally fills the entire filter state with the calculated channel quality measurements. Yet another embodiment uses the hysteresis and threshold parameters in conjunction with the initial codec mode to calculate an initial fill value for the filter state.
