Abstract
A land mobile radio communication system has a plurality of cell cites, each of which includes a plurality of repeaters. The mobil radios in the cell transmit and receive both data and audio. The date component of the signal is carred as low-frequency subaudible information. In operation the system determines the number of repeaters that are available. When the system has determined that more than a predetermined number of the repeaters are available, all of the repeaters are set to repeat audio and to transmit and to receive data. However, when the system determines that only the predetermined number of repeaters are available, all of the repeaters, except for the ones of the repeaters in the predetermined number, are set to repeat audio and to transmit and receive data. The ones of the repeaters in the predetermined number are set to only transmit and receive data.

7490159 - Methods and systems for dynamic information transmission - Owned by Qisda Corporation (Taoyuan County,TW)

Methods for dynamic information transmission. Data objects having the highest broadcast positions respectively in the data object sequences are acquired as multiple candidate data objects. A measure for each candidate data object is calculated using a GMF (gain measure function). One candidate data object is pushed in an output queue contingent upon the measures thereof, enabling the pushed candidate data object to be transmitted before the other candidate data objects to a client apparatus via the output queue.

7577439 - Method of controlling traffic, radio system, remote unit and base station - Owned by Nokia Corporation (Espoo,FI)

A radio system includes one or more remote units in each cell coverage area controlled by a base station. The remote units communicate with one or more terminals of the radio system. The remote units are configured to detect traffic parameters of one or more terminal signals within the coverage area of each remote unit. The base station is configured to receive the signals related to the detected traffic parameters from the remote units. The base station also is configured to calculate relative average traffic levels between the remote units on the basis of the received signals related to the traffic parameters from the remote units, and to allocate traffic transfer resources in the radio system on the basis of the calculated relative average traffic levels between the remote units.

7565106 - Wireless signal repeater with temperature and time display - Owned by Sprint Spectrum L.P. (Overland Park, KS)

A wireless signal repeater will function to boost the strength of signals being communicated wirelessly between a base station and a mobile station. At the same time, however, the wireless signal repeater will read control channel messages transmitted by the base station and will obtain from the messages an indication of outside temperature and an indication of local time. The repeater will then display the outside temperature and local time information for viewing by a user. Advantageously, the repeater will thus become a more functional object in the eyes of the average lay-person, rather than functioning merely to boost wireless signal levels.

6374115 - Method and apparatus for trunked radio repeater communications with backwards compatibility - Owned by Transcrypt International/E.F. Johnson (Waseca, MN)

A trunked radio repeater communication system capable of use in a networked system includes a plurality of distributive switches and a unique signaling protocol and a switching protocol for interconnecting the trunked transmission communications systems into a wide area network that provides an expanded feature set of radio communications capabilities. The trunked radio repeater system including a protocol supporting communications for repeaters and/or subscribers conducting communications using existing protocols, such as the Logic Trunked Radio (LTR) protocol and supporting additional special functions.

6804529 - Trunked radio repeater communication system including home channel aliasing and call grouping - Owned by Transcrypt Internationall E. F. Johnson Company (Burnsville, MN)

A system for channel assignment in a trunked transmission communication system including a plurality of subscribers. A plurality of subscribers is provided home channel assignment to reduce collisions. A home channel alias is provided for home channel coverage where a designated home channel is unavailable. A system for call grouping is provided to avoid talk group splitting. A first check is used to determine if other channels are conducting communications with identical home and talk group information. A second check is available after a temporary channel assignment. In one system both the home channel aliasing and call grouping are performed.
