Abstract: In an embodiment, a server obtains a user-specified mixing preference (USMP) for an access terminal (AT) in a communication group that is different than a default mixing rule for the group communication session. The server grants non-exclusive floors to a subset of ATs in the communication group, receives media frames from each AT in the subset and generates an output frame by selectively mixing the received media frames based on the USMP, after which the output frame is sent to the AT. In another embodiment, the AT obtains the USMP and receives unmixed versions of the media frames and then selectively mixes the received media frames at the AT based on the USMP. In another embodiment, an AT detects speech and requests the floor, and the AT buffers speech while waiting for the floor request to be granted.

Abstract translation: 在一个实施例中，服务器获得用于与用于组通信会话的默认混合规则不同的通信组中的接入终端（AT）的用户指定的混合偏好（USMP）。 服务器向通信组中的AT的子集授予非独占楼层，从子集中的每个AT接收媒体帧，并且基于USMP选择性地混合接收到的媒体帧并产生输出帧，之后发送输出帧 到AT。 在另一个实施例中，AT获得USMP并接收媒体帧的未混合版本，然后基于USMP在AT处选择性地混合接收到的媒体帧。 在另一个实施例中，AT检测语音并请求楼层，并且AT在等待发起请求被授予时缓存语音。
