Abstract

In connection with a push-to-talk-over-cellular (PoC) function of a cellular telephone, the user interface of the cellular telephone presents certain information to the user of the cellular telephone concerning a current group call session. The information may include an indication of what proportion of the members of a group designated for the group call session are currently active. In addition, the user interface may provide a list of the members of the designated group, with icons indicating the current status of the group members. When a member of the group is currently talking, the talking member's name may be displayed by the user interface.
