111. The system of claim 102, wherein means for determining a contextual parameter of the group communication session further comprises means for transmitting a signal indicating that a priority level of a group communication session changed by at least one participant in the group communication session.

112. The system of claim 102, the computing device further comprising:

means for ranking a plurality of group participants; and

means for determining the contextual parameter based on the ranking.

113. The system of claim 102, the computing device further comprising:

means for adding additional group participants;

means for ranking the additional group participants and the at least two participants; and

means for determining the contextual parameter based on a change of the ranking.

114. The system of claim 102, wherein:

means for determining a contextual parameter of the group communication session comprises means for receiving data from a sensor on a communication device of one or more of the at least two participants in the group communication session; and

means for taking action in the group communication session based on the contextual parameter comprises;

means for receiving a message including a request for providing instructions to a participant of the group communication session providing the sensor data; and

means for transmitting resource allocation parameters for the dynamic point of control entity to provide the request for instructions.

115. The system of claim 102, wherein means for taking action in the group communication session based on the contextual parameter comprises means for transmitting an alert message that comprises at least one of means for an alert if a boundary is crossed, means for an alert if a predetermined talk time is exceeded, means for an alert a sensor has been triggered and means for a mute, or means for an alert action if a background noise exceeds a predetermined level.
