An embodiment takes the form of a process that includes transmitting video frames to a receiving device during a first transmission period of one or more time slots of a half-duplex air interface, and receiving feedback messaging from the receiving device during a feedback period of one or more time slots of the half-duplex air interface. The process further includes suspending, after the first transmission period, transmission of video frames for a suspension period of one or more time slots of the half-duplex air interface, and after the feedback period and after the suspension period, transmitting one or more recovery frames to the receiving device during a recovery period of one or more time slots of the half-duplex air interface. The one or more recovery frames collectively include inter-coded macroblock data and/or intra-coded macroblock data.

A communication system () comprises a plurality of mobile stations () each operable to communicate with other communication stations by a wireless link of a first kind, at least one location indicator () operable to detect by a wireless link of a second kind a location of at least one () of the mobile stations when the at least one mobile station is within a communication range of the location indicator, at least one proxy location server () operably coupled to at least one associated location indicator (), and a location server () operable to communicate with the at least one proxy location server to receive a notification of the location of the at least one mobile station () when detected to be within communication range of the associated location indicator ().

A method and apparatus is disclosed for dynamically activating gateway functions on a communication device which is operating in trunked mode. The communication device calculates an estimated probability that at least one associated communication device is out of a network coverage area. The communication device determines that the associated communication device is inaccessible or is operating in an operating mode consisting of a trunked mode or a direct mode when the estimated probability is calculated to be at or below a predefined threshold. The communication device automatically activates its gateway functions and is configured to function as a direct mode gateway for at least one associated communication device when it determines that the associated communication device is operating in the direct mode.

A mobile station () operable in a wireless communication system (), the mobile station including means (of) for reporting to a location server () of the system a current location of the mobile station and a controller (of) for controlling the means for reporting to report to the location server a current location of a second mobile station () detected to be near to the mobile station. A wireless communication system () in which the mobile station is operable and a method () operable in the system are also described.
