Abstract: A product and method for preventing a connector from rotating when a mating connector is attached to, or detached from, the connector. When a nut on the connector is tightened, a washer is compressed in a groove in a panel to which the connector is attached. Edges on the outer perimeter of the washer press against the edges of the groove, thus preventing the washer from rotating in relation to the panel having the connector. A portion of the washer's cutout presses against flat regions on the connector and, in conjunction with the groove in the panel, prevent the connector from rotating when attaching or detaching cables.

Abstract: Apparatus, and an associated method, for maintaining a selected QoS (quality of service) level of communications by a mobile station as the mobile station travels throughout an area encompassed by a radio communication system. Subscriber QoS classes are defined. One of the QoS classes is selected pursuant to a service subscription permitting the mobile station to communicate in the radio communication system. The selected QoS class is stored at a service subscription register. During communications with the mobile station, resources are reserved for use by the mobile station at a level corresponding to the selected QoS class.

Abstract: A hands-free adapter for interfacing a mobile phone handset with an existing audio system attaches to the handset by means of the accessory connectors that are generally located on the bottom or back of the handset. The adapter modulates the received audio from an in-coming call with a pre-selected FM or AM carrier frequency, and broadcasts the resulting, low power signal to the antenna of a receiver of the existing audio system, which may include a home stereo system, a portable stereo system, or a vehicle radio. The receiver is tuned to the carrier frequency used by the adapter so that the in-coming audio from the mobile phone can be heard over the audio system speakers. For Radio Data System (RDS)-capable radio receivers, a processor is provided within the adapter to generate channel data, which is then transmitted with the carrier signal. The RDS-capable radio receives the RDS signal and automatically tunes itself to the selected channel.

Abstract: A method for synchronization of a receiver to a direct sequence spread spectrum (DS-SS) signal in a telecommunications system. A verification process is performed in the receiver upon initial detection of a first DS-SS signal prior to attempting synchronization to a second signal. In the verification, a window search is performed in a window centered on the PN phase of the initially detected first signal. A number K of search passes are made, each on M PN offsets. At least one parameter for each of the K window search passes is saved. The at least one parameter from each pass is then processed according to a predetermined algorithm. Based on the results of the algorithm, a decision is made as to whether or not to attempt synchronization to the second signal or to restart the search.

Abstract: A mobile radio antenna configuration scheme. A first embodiment discloses an extendable first antenna for a mobile radio that can serve as an alternative to, or in conjunction with, an internal second antenna. When in the stored position, the first antenna is disposed within the mobile radio casing so that the form factor advantages of using internal antennas are obtained. When fully extended, the majority of the first antenna is external to the mobile phone. In another embodiment, the mobile radio transceiver engine is switched from the second antenna to the first antenna upon extension of the first antenna. In another embodiment, the transceiver is connected to both antennas. In another embodiment, the antenna with the strongest signal is connected to the transceiver when the extendable antenna is extended. In another embodiment, an antenna module inserts into a mobile radio. The antenna module may have various antenna combinations for custom configuration of the mobile radio.

In an embodiment of the invention, the holder includes a cradle unit that has a securing mechanism including a securing pin flexibly formed on the top end of the cradle unit and a securing pocket formed on the bottom end of the cradle unit. A mobile telephone may be secured in the cradle by placing the bottom portion of the mobile telephone in the securing pocket and moving the mobile telephone into the cradle unit, allowing the securing pin to snap into a securing notch that is formed on the top portion of the mobile telephone. The cradle unit may be formed of a single piece body. The cradle unit may also be formed to encompass the mobile telephone to provide a better tactual grip than is provided by the body of the mobile telephone alone.

Abstract: This invention applies to a mobile station that is able to determine a required data rate based on data buffer usage. If the data buffer indicates a requirement for a high data rate transmission, the mobile station sends a request to a base station to be assigned multiple parallel code channels. If the multiple parallel code channels are granted, the mobile station uses the channels for transmitting data to the base station until either the data buffer becomes empty, or a base station time-out occurs, or the mobile station is signalled by the base station to reduce its data transmission rate, whichever occurs first. The mobile station of this invention is enabled to autonomously control the data rate during an assigned period for high speed transmission, so as to lower the data rate when needed for the purpose of improving coverage and/or to avoid operating in a power limited condition, thereby degrading link quality.

Abstract: A method and system for operating a CDMA cellular telecommunications system having beamforming antennas in combination with other antenna access techniques. System capacity and demand on system resources are dynamically adjusted using beamforming antennas for some mobile stations, and other antenna access techniques for other mobile stations. Forward link channels on the beamforming and non-beamforming antennas are dynamically allocated among mobile stations depending upon resources available and the type of channel required by each mobile station. Forward link channels requiring a higher data rate, above a predetermined threshold, may be assigned to channels transmitted on beamformed antennas. In an embodiment of the invention, the cellular system includes beamformed and non-beamforming antennas.

Abstract: In a packet data transmission and reception system a media access control (MAC) message is broadcast by a base station to a plurality of mobile stations. The MAC message contains packet data transmission scheduling information which allows the base station to preemptively control mobile station access to traffic channels in order to maximize the efficiency of packet data transmissions and allow scheduling consideration including priority access, quality of service and maximum bytes per transfer. The MAC message consists of a control frame structure which comprises scheduling parameters including MAC IDs fields, activity fields, and a field representing the number of free traffic channels in a cell. These parameters enable multiple mobile stations to share, in a time multiplexed fashion, traffic channels for packet data transmission on CDMA based mobile communication systems.

Abstract: A method and system for mobile assisted hand-off between base stations using different carrier frequencies in a Code Division Multiple Access (CDMA) cellular system. In the method and apparatus, a mobile station performs handoff measurements on forward link transmissions of handoff candidate CDMA base stations, where the forward link transmissions are transmitted on a carrier frequency that differs from the forward link carrier frequency of the current base station. The handoff measurements are performed during selected transmission frames that define transmission periods on the reverse link by the mobile station. During the measurement time in the selected transmission frame, the mobile station does not receive (punctures) data sent to it on the forward link, and does not transmit data on the reverse link.

Abstract: A method and apparatus for controlling a retransmission/abort timer in a telecommunications system. A pointer, V(P), that points to the upper bound of retransmitted data frames in a receiver buffer is introduced. A list includes at least one entry indicating a missed data frame for which a retransmission request has been transmitted. The entry is associated with a retransmission/abort timer that is started upon transmission of the retransmission request for the data frame. Once a retransmission timer is started, any received data frame type, whether valid or not, is counted in the incrementation of the retransmission/abort timer for an unreceived data frame. However, if the received data frame is not a valid data frame, any expiration action on the retransmission/abort timer is disabled. Also, anytime any valid frame is received, an expiration action may be taken on the retransmission timer of unreceived data frames having a sequence number less than V(P).

Abstract: A method and apparatus for varying the data transmission rate of a code division multiple access (CDMA) telecommunications system. The method and apparatus may be implemented into an existing system operating according to a standard designed for a base data transmission while utilizing the Walsh modulator length, the data transmission frame structure, the channel encoding scheme, or the I/Q modulation level of the existing system. Serial data is input to a transmitter/modulator at a data rate which is higher than the base data transmission rate. The serial data is received over a time period having a duration equal to the duration of the transmission frame and demultiplexed into a plurality of sets of input data. Each of the plurality of sets of input data is then processed in one of a plurality of subchannels using the system channel encoding and interleaving scheme to generate a plurality of sets of processed data.
