Publication number: 20040032843Abstract: A mobile device (80) is coupled to a dispatch server (50) via a mobile network (60, 70) and an internet protocol network (40). The mobile device triggers a push-to-talk request which is processed by the dispatch server. The dispatch server then transmits this push-to-talk request to a family radio service (FRS) gateway (30). FRS gateway (30) converts this digital request to an analog request and broadcasts the request via a base station 20 to a family service radio (10). The FRS radio can broadcast back to the FRS gateway, which will vocode the analog request, and transmit it back to the mobile device via the dispatch server. This invention allows mobile devices (cellular) equipped with PTT applications to network with FRS radios.Type: ApplicationFiled: August 15, 2002Publication date: February 19, 2004Inventors: Bradley R.

Patent number: 5509004Abstract: A communication network (10) includes a constellation of satellites (12) in orbit around the earth. Gateways (14) communicate with the satellites (12), reside on the surface of the earth, and interface the network (10) to the local PSTN (18). User units (16) communicate with satellites (12) and provide communication services to users. A gateway (14) includes a mobile switching center (22), which connects half-calls, and an earth terminal controller (20), which occasionally overrides connections defined in the mobile switching center (22). When possible, communication paths connected at the mobile switching center (22) are intraswitched at one or more satellites (12) rather than being routed through the mobile switching center. However, when supplementary services are requested, the communication path is reconfigured back to the mobile switching center (22) so that additional signals may be inserted into the communication path.Type: GrantFiled: August 1, 1994Date of Patent: April 16, 1996Assignee: Motorola, Inc.Inventors: James W.

Patent number: 5383185Abstract: A method and apparatus for data collision detection and resolution in a multi-processor communication system. The system includes a plurality of processors coupled via a common bus. When it is required that one processor communicate with another processor, the first processor determines whether a data collision flag is set. The processor then checks a number of indicators to determine whether the identity of the transmitting processor is what it is expected to be. If a data collision is found, the processor waits a selective time before transmitting a message. The processor then repeats the data collision checking and transmitting the message to the other processor when no data collision is found. The time to wait is dependent upon the identity of the processor and is table driven.Type: GrantFiled: September 20, 1993Date of Patent: January 17, 1995Assignee: Motorola, Inc.Inventors: Peter J. Armbruster, James A. Stephens
