Abstract: Systems and methods for controlling the power level for a mobile station during periods when no data is being transmitted by the mobile station. In one embodiment, data is intermittently transmitted from a mobile station to a base station on a reverse-link traffic channel. When data is being transmitted on the traffic channel, the transmitted data is used by the base station to perform power control operations (e.g., incrementing or decrementing the mobile station's power level, based upon comparison of a received SNR to a target SNR). When no data is being transmitted on the traffic channel, a “zero-rate indicator” is transmitted on the rate indicator channel. The zero-rate indicator is used by the base station to perform power control. Power control based on the zero-rate indicator may use velocity profiles, reliability metrics or other techniques to control adjustment of the power level.

Abstract: Apparatus for network communication includes a cable arranged to form a wired local area network (LAN), the cable comprising at least first and second conductors. A plurality of access points are interconnected by the cable and are arranged in a wireless local area network (WLAN) to communicate over the air on a common frequency channel with a mobile station. The access points are adapted to convey data to and from the mobile station over the LAN via the first conductor and to exchange control messages among the access points via the second conductor.

Abstract: In a system in which multiple remote units compete for limited communication resources, a remote unit accesses the system by randomly selecting a first sequence from a set of predetermined sequences. The remote unit transmits a data bit stream modulated with the first sequence beginning at one of a set of recurring admission boundaries. If the remote unit determines that the data bit stream has not been successfully received at a hub station, it randomly selects a second sequence from the set of predetermined sequences. The remote unit transmits the data bit stream modulated with the second sequence beginning at one of the set of recurring admission boundaries.

Abstract: A received signal level is controlled in a node used in a point to multi-point (PmP) radio-communication system having microwave time division multiple access (TDMA). Local node control is activated by an AGC in the receiving node, and simultaneously, a radio control loop is activated from the receiving node to each terminal regulating each terminal's transmitted power level. The receiving node AGC reconfigures quickly and is both accurate and stable.

Abstract: Program guide information of the program to be broadcast by the broadcast station 1 is reserved in the EPG server 15 of the center station 11. The EPG server 15 retrieves for each user, the program satisfying the conditions such as the category of the program registered in the personal information database 16, and then transmits the guide information of the retrieved programs to the portable telephone 14 of a user who has set the conditions, via the communication network 10. Thereby, even if the user is outside the home, if there is a program satisfying the conditions specified by the user, the user can obtain the information concerning the program by utilizing the portable telephone 14. Then, the user can instruct, with reference to the obtained program information, a recording operation from the portable telephone 14 to the VTR 6 in the home 12.

Abstract: A communication system includes a mobile terminal and a base station. The mobile terminal estimates signal quality of a forward link during a first power control group period and determines a power control bit based on the estimated signal quality. The mobile terminal further transmits the power control bit on a reverse link during the first power control group period. The base station receives the power control bit on the reverse link and modifies forward link power based on the power control bit at commencement of a second power control group period.

Abstract: Frequency synchronization bursts are detected for a radio communication system such as a GSM cellular telephone network using a two stage correlation process. A first unit performs a first set of correlations to identify receipt of the frequency synchronization burst. A preliminary identification is declared when the moving average of the first set of correlations, normalized for received power, exceeds a threshold value for a number of contiguous samples. After a preliminary identification is made, a second unit performs a second set of correlations to confirm the detection of the frequency synchronization burst. The second correlations are preferably also normalized and confirmation of detection is declared when the normalized moving average of the second stage correlation exceeds a threshold value for a number of contiguous samples.

Abstract: Methods and systems are provided for communicating data from wireline terminals to mobile terminals in a telecommunications network, which includes a home node associated with the mobile terminal and one or more visited nodes. To establish communication with a mobile terminal, a wireline terminal sends data to a server in the telecommunications network. The server identifies a mobile identification number associated with the mobile terminal, and based on the identified mobile identification number, the server determines a route that excludes the home node when the mobile terminal is out of the geographical area served by the home node. The server then establishes via the determined route a connection to the mobile terminal and sends to the mobile terminal the data received from the wireline terminal.

Abstract: A tradesworker's radio has a weather and impact resistant features to enable a tradesworker to use the radio under adverse working conditions, such as construction or other work sites. Louvered grills covering moisture resistant loudspeakers are angled downward to protect the speakers from direct splash in case the radio is left outdoors in a heavy downpour. A layer of felt-like material is interspersed between the louvered grills and the loudspeaker cones to offer improved moisture resistance. A non-telescoping antenna of the rubber covered spring type material folds neatly into recess when not in use. The controls include waterproof pushbuttons for on/off, volume adjustment, a weather channel, AM/FM selection and tuning. Elastomeric blocks are bonded to the interior of the housing and the blocks have bonded threaded studs, which are used to shock mount the radio circuit board to the inside of the housing. This circuit board is treated with a conformal coating to improve its moisture resistance.

Abstract: Techniques for measuring signal quality in a communications link supporting OFDM symbol transfer across plural sub-carriers are disclosed. These techniques employ a link interface receiving OFDM symbol(s) from the link, and a signal-to-noise ratio (SNR) estimation unit generating an estimate of a geometric SNR (SNRgeo) for the received symbols based on an average of the logrithmic difference between soft decision and hard decisions for the received symbol. SNRgeo here defines a scalar measure of the link signal quality, which results in a computationally efficient yet accurate link signal quality assessment, and thereby permit selective link characteristic alteration. Only sub-carrier subsets need be used to derive a relatively an accurate SNRgeo estimate. Sharing calculation resources between SNR estimation and soft decision units further reduce implementation complexity.

Abstract: A method for adjusting an OLT for power control, which is capable of closely tracking a low tFER. The OLT is adjusted based on frame quality indicator FQI and channel quality metrics. FQI and channel quality metrics are generated at the receiver of a base transceiver station after reception of a frame. If FQI equal to a logic zero was generated, the OLT is adjusted upwards using a first stepsize. If FQI equal to a logic one was generated for a certain amount of consecutive frames, the OLT is adjusted downwards using a second stepsize. The OLT is also fine-tuned during the intervals between the transitions caused by applying the first stepsize or second stepsize. The first and second stepsizes and the amount of consecutive frames of FQI=1 before OLT is adjusted downwards are determined adaptively according to time-varying channel conditions and received frame quality indicator.

Abstract: A method for enhancing the accuracy of Advanced Forward Link Trilateration (AFLT) position location calculations is disclosed. A position determination entity (PDE) constructs a statistical database of pilot phase measurements reported by mobile stations (MSs) located in a geographic region about a reference base station (BS). When a MS's location is to be calculated, the MS reports a set of PN phase offsets to the PDE. Using only that set of PN phase offsets, the PDE determines a rough estimate of the MS's location using conventional AFLT and also determines the region within which the MS is located. If the PDE determines that the MS did not report one or more earlier arriving PN phase offsets but reported a delayed multipath component, the PDE sends a message to the MS to look for an earlier arriving PN phase offset at a certain time prior to the reported PN phase offset.

For example, a single telephone number can be assigned to a service provider to access all devices telemetered by that service provided. Advantageously, this arrangement provides for an inexpensive method and apparatus for accessing customer devices.

Abstract: The communication terminal apparatus measures reception quality and reports the measurement result to the base station apparatus, and the base station apparatus switches the transmission rate based on the reported result of the reception quality. In this way, the transmission rate is switched starting at the point in time at which the reception quality of the communication terminal apparatus deteriorates. Furthermore, the transmission rate is switched so that the amount of interference with others is within the allowable range according to the channel condition between the communication terminal apparatus and base station apparatus.
