Sub-group communication in a direct mode of operation
First Claim
1. A mobile station that communicates with other mobile stations within a mobile communication network, the mobile station comprising:
- a radio unit that receives and transmits communications;
a push-to-talk key selectively positionable in one selected from a group consisting of an activated state and a deactivated state; and
a controller coupled to the radio unit and the push-to-talk key, the controller configured todetect a request to transmit an outgoing communication,determine whether the push-to-talk key is in the activated state or in the deactivated state,select a first power level when a determined state of the push-to-talk key is the activated state,select a second power level when the determined state of the push-to-talk key is the deactivated state, andtransmit, via the radio unit, the outgoing communication on a current operating channel to at least one other mobile station within the mobile communication network at the selected power level.

Abstract
Sub-group communication during a direct mode of operation of mobile stations in a mobile communication network. A controller in a mobile station detects a request to transmit an outgoing communication and determines whether a push-to-talk key is in an activated state or in a deactivated state. The controller further selects a first power level when a determined state of the push-to-talk key is the activated state, and selects a second power level when the determined state of the push-to-talk key is the deactivated state. The controller also transmits, via the radio unit, the outgoing communication on a current operating channel to at least one other mobile station within a mobile communication network at the selected power level.

14. A method of operating a mobile station within a mobile communication network, the method comprising:
-
detecting, via a controller, a request to transmit an outgoing communication; determining, via the controller, whether a push-to-talk key is in an activated state or in a deactivated state; selecting, via the controller, a first power level when a determined state of the push-to-talk key is the activated state; selecting, via the controller, a second power level when the determined state of the push-to-talk key is the deactivated state; and transmitting, via a radio unit coupled to the controller, the outgoing communication on a current operating channel to at least one other mobile station within the mobile communication network at the selected power level. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
