Abstract: A dispatch translation server (DTS) translates messages between a first dispatch communication network that uses a first protocol and a second dispatch communication network that uses a second protocol. The messages relate to the setting up of a dispatch communication session, controlling the channel floor of the dispatch communication session, and terminating the dispatch communication session. With regard to controlling the channel floor, dispatch translation server (DTS) translates messages when both the first and second dispatch communication networks use explicit floor control; when the first dispatch communication network uses implicit floor control and the sending party resides therein and the second dispatch communication network uses explicit floor control; when the first dispatch communication network uses explicit floor control and the sending party resides therein and the second dispatch communication network uses implicit floor control; and when both the first and second dispatch communication network use implicit floor control.

Abstract: Systems and methods for a dispatch communication router are provided. The dispatch communication router allows calls between two or more dispatch communication networks which operate using different dispatch communication protocols. The dispatch communication router includes a protocol interworking function, a media control stack and a transcoding function. The dispatch communication router also includes a dispatch technology protocol stack for each different dispatch communication protocol supported by the router. The dispatch technology protocol stack converts dispatch communication signaling of a particular dispatch communication technology into a common protocol. The dispatch technology protocol stack can also convert dispatch communication media into a common dispatch communication media protocol and media format, or a separate transcoder can be provided to perform such conversion. The dispatch communication router of the present invention allows support of new dispatch communication technologies by adding a new dispatch technology protocol stack and communication coders (if necessary).

Abstract: Systems and methods for enabling a PTT user to communicate with an FDV user on a personal PTT communication appliance are provided. The PTT user communicates with the FDV user by connecting to a PTT to FDV system associated with a PTT network and a FDV network. The PTT to FDV system allows users on both PTT and full-duplex networks to communicate rapidly, efficiently, without requiring change in user behavior, without unnecessary speech cutoff, and without requiring technology modifications on either network.

Abstract: A system and method for context-assisted information retrieval include a communication device, such as a wireless personal communication device, for transmitting screen-context information and voice data associated with a user request to a voice information retrieval server. The voice information retrieval server utilizes the screen-context information to define a grammar set to be used for speech recognition processing of the voice frames; processes the voice frames using the grammar set to identify response information requested by the user; and convert the response information into response voice data and response control data. The server transmits the response voice data and the response control data to the communication device, which generates an audible output using the response voice data and also generates display data using the response control data for display on the communication device.

Abstract: A system, method and computer program product which allows both mixing (e.g., PC-based) and non-mixing (e.g., phone-based) clients to participate in a single audio conference. The system includes a hybrid multi-point control unit (i.e., conferencing server) that performs mixing for phone-based clients and multiplexing for PC-based clients. The method and computer program product determines which clients have the capability to mix multiple audio streams and which do not. For those clients capable of mixing, the server multiplexes the packets of audio data received from each client on the active speakers list into a multiplexed stream. For those clients that are not capable of mixing, the server mixes the packets of audio data received from each client on the active speakers list into one combined packet.
