    Abstract: A media server and method of operation of a media server in a wireless communication system are provided. The media server receives media streams from mobile communication devices in the wireless communication system, and routes the media streams sequentially to a packet header compression encoder. A processor of the media server is configured to receive a first media stream from a first mobile communication device, receive a request from a second mobile communication device to transmit a second media stream to the media server, and transmit data derived from an RTP header of the first media stream to the second mobile communication device. The second mobile communication device is enabled to commence transmission of the second transmitted media stream using the data derived from the RTP header. The wireless communication system may be a PTT wireless communication system or a group video wireless communication system.

    Abstract: A method and a system for operating a subscriber unit to seamlessly switch between a trunked mode operation (TMO) and a direct mode operation (DMO) in a communication system. The communication system includes one or more subscriber units communicating in trunked mode operation on a first communication channel via a base station and the subscriber units communicating in direct mode operation on a second communication channel via a direct mode gateway station. When the subscriber units communicate in the TMO and when the signal quality on the first communication channel is below the predetermined threshold, the subscriber units automatically switch to the direct mode operation. When the subscriber units communicate in DMO and when the signal quality on the second communication channel is below the predetermined threshold, the subscriber units automatically switch to the trunked mode operation.

    Abstract: Disclosed herein are methods and systems for node operation according to network-wide resource-allocation schedules. One embodiment takes the form of a method carried out by a given node within an ad-hoc wireless network, which includes a controller node for a current time period. The method includes obtaining one or more air-interface resource requests for the current time period, where each obtained resource request indicates a requesting node and a requested resource. The method further includes using a network-standard algorithm for deriving a network-wide resource-allocation schedule for the current time period based at least in part on the obtained resource requests. The method further includes verifying the derived resource-allocation schedule based at least in part on a verification value derived by the controller node from the network-wide resource-allocation schedule using a network-standard verification function. The method also includes operating according to the verified resource-allocation schedule for the current time period.

    Abstract: A lossless call may be established over a wireless radio network by determining, at a target subscriber device during a received call, that one or more identified media items in a stream of media items of the call being received over a first radio channel was not successfully received, and responsively: continuing to receive first subsequent media items of the call and buffering, instead of rendering at the target subscriber device, the first subsequent media items, requesting the identified media items, receiving by the target subscriber device via an established second radio channel, different from the first radio channel, the identified media items, re-ordering the identified media items chronologically with respect to the buffered first subsequent media items to create the re-ordered subsequent media stream, and rendering, by the target subscriber device, the re-ordered subsequent media stream at a first increased relative rate.
