Abstract: A method and system for direct mode operation (DMO) of a talkgroup enables device to device (D2D) DMO operation leveraged from a Land Mobile Radio (LMR) system. The method includes scanning at a radio receiver a defined radio frequency spectrum; receiving at the radio receiver in the defined radio frequency spectrum a wake-up signal; identifying a talkgroup identifier in the wake-up signal, wherein the talkgroup identifier corresponds to a talkgroup being monitored by the radio receiver; in response to identifying the talkgroup identifier, decoding code sequences included in the wake-up signal; identifying in at least one of the code sequences both a center frequency and a transmission bandwidth of the DMO transmission; and tuning the radio receiver to receive the DMO transmission at the center frequency and transmission bandwidth.

Abstract: A method and apparatus for multicasting data streams in a wireless radio communication system are provided. A server assigns a plurality of data streams amongst RF resources. One or more points-of-access of the wireless radio communication system are operable to transmit each RF resource to mobile communication devices. Responsive to a request from a mobile communication device for a selected one of the plurality of data streams, the server identifies the points-of-access that have not been assigned, and hence cannot transmit, the RF resource to which the selected data stream is assigned. An access controller instructs those points-of-access to deny association to the mobile communication device. The server then multicasts the selected data stream to the mobile communication device through one of the remaining points-of-access that can transmit the selected RF resource.

Abstract: A method and apparatus for linking to a Peer-to-Peer (“P2P”) network for VOIP communications. An intermediary peer creates a map to link peers together in the P2P network. A series of messages are generated to open the ports of one peer to be accessible to other peers on the P2P network. Peers are then enabled to communicate directly with other peers. Steward peers can assume the functionality of the intermediary peer.

Abstract: A method for managing floor control in a network is disclosed. The method includes beginning a ballot timer when at least one of a) a first node packet is created at the node and b) a second node packet is received at the node from a second node. The first node packet comprises a first timestamp and the second node packet comprises a second timestamp. The ballot timer runs for a first predefined time interval. The method further includes determining a floor holder upon expiration of the first predefined time interval based upon an earliest time of the first timestamp and the second timestamp. Further, the node and the second node have a same absolute timing reference.

Abstract: A method for the selection of forward error correction (FEC)/constellation pairings (800) for digital transmitted segments based on learning radio link adaptation (RLA) including formatting a packet transmission having a predetermined number of information bits (801). The packet is then split into a plurality of segments (803) where an RLA is used (805) to determine the optimum format of the packet. The plurality of segments is then sent to a channel encoder for FEC encoding and symbol mapping (807) at a rate selected by the RLA. The segments are then formatted into packet blocks (809) and transmitted in blocks that form a time slot at a constant symbol rate.
