Abstract: In systems which transmit both GSM modulated and EDGE modulated signals, time of arrival estimations can be improved without requiring the detection of the type of modulation used on the received signal. In accordance with the present invention, a received signal is initially demodulated by a receiver in accordance with a first demodulation scheme. The demodulated signal is split into two copies. Taking into account the initial demodulation, one of the copies is demodulated in accordance with another demodulation scheme, thereby resulting in a first signal demodulated in accordance with the first demodulation scheme and a second signal demodulated in accordance with a second demodulation scheme. A training sequence is used to correlate the two signals which are then summed in a incoherent integration process. The result of the incoherent integration is used to estimate the time of arrival of the received signal.

Abstract: A receiver receives analog signals at radio frequency (RF), and the RF analog signals are converted into the digital domain. As such, the receiver does not require frequency conversion stage(s) prior to analog to digital conversion. For example, the receiver can comprise at least one antenna(s) which receives radio frequency (RF) analog signals at different frequency bands. The analog RF signals are provided to a single analog to digital (A/D) converter, and the A/D converter converts the analog RF signals at the different frequency bands into digital signals within the Nyquist bandwidth. By properly selecting the sampling rate of the A/D converter for the RF analog signals, the A/D converter can produce replicas of the different frequency bands of the analog signals in non-overlapping portions of the Nyquist bandwidth.

Abstract: An amplifier for high gain, narrowband signal amplification is disclosed. An embodiment is an amplifier including a first means capable of oscillating and a second means for controlling the operating state of the first means between oscillation and close to oscillation. By operating close to oscillator high gain, narrowband signal amplification occurs. By operating between oscillation and close to oscillation, rather than between startup and close to oscillation, the amplifier is always narrowband. Accordingly, an advantage of the invention is operation with minimum affect from interfering.

Abstract: A wireless telecommunication network communicates with a population of subscriber units. A portion of the subscriber units may be programmed to practice a less desirable service configuration, such as a default 13 kb/s vocoding process, even though capable of practicing a more desirable service configuration, such as enhanced variable rate coding (EVRC). Another portion of the subscriber units may not be capable of performing the more desirable service configuration. The network includes a database used to filter the application of a negotiation process during call setup for calls originating at the subscriber units. The negotiation process requests subscriber units to implement the more desirable service configuration. The database is automatically populated through an exchange of messages which occurs during a call setup process for incoming calls to the subscriber units.

Abstract: A method and a system for determining a channel mask in a network device in a microcellar network are provided. An exemplary embodiment uses a weighted average of the background noise on a channel of the network device to determine whether the channel should be masked out. One embodiment provides a method for determining a group of channels from a plurality of frequency hopping channels received by a wireless communications device, the channels in the group being excluded from receipt by the wireless communications device. The method includes the steps of determining an indicator based on a received noise measurement at a first time for a channel, then determining a weighted average at a second time for the channel, the weighted average including the indicator, and then selecting the channel as a member of the group, upon an indication that the weighted average at the second time is above a threshold.

Abstract: An integrated wireless-global positioning system determines the location of a wireless terminal from satellite measurements and wireless network measurements. The accuracy of the location identified is dependent upon the quality of the measurement from the wireless network which, unfortunately, can contain measurement errors such as biases. Biases are caused by time delays which occur during the processing and transmission of signals. The time delays vary for each sector/base station and for each type of wireless terminal model being used. Calibration of these biases is important for the success of the integrated wireless global positioning system. For a small network system which has only a handful of base stations/wireless terminals, a specific system to calibrate the time delays for each base station and/or wireless terminal can be set up. The approach is, however, costly, time consuming, and subject to many errors.

Abstract: Method and device for determining a signaling address of a mobile services switching center in a cellular communication system offering both circuit switched and packet switched services are disclose. The method is based on that, instead of using information on the location of a terminal equipment, information on the equipment of the system being used for reaching a terminal equipment is used for determining the mobile services switching center, in the service area of which the terminal equipment is located. The signaling address is determined on the basis of the knowledge of such information. For this purpose, for instance, allocation tables or sorting trees are used, which allocate the sought for signaling address to one or more equipment or to an information identifying one or more equipment.

Abstract: A Personal Access Communications System (PACS) subscriber unit (SU) layer 3 interface is designed as a finite state machine that includes a unique slot seizing state. All transitions from a null state that require traffic channel seizing first transition to the slot seizing state before transitioning to another associated handling state. While in the slot seizing state, the SU layer 3 interface state machine awaits confirmation of traffic channel establishment.

Abstract: A radio repeater wherein a reflective negative resistance amplifier, using the negative resistance of a Gunn diode, is applied at one side of a dielectric waveguide, enabling signals to be inputted through the input terminal dielectric waveguide, circulated in the circulator and enter the Gunn diode. Reflected waves amplified in the Gu diode exit the output terminal dielectric waveguide. A radio repeater is provided on the non-radiative dielectric waveguides using the multi-space non-radiative dielectric waveguides, which receives a frequency, amplifies it, and retransmits the amplified signals to any direction. With a dielectric band inserted in the radio repeater, directions for reception and transmission can be freely changed. Using the radio repeater, a small size radio repeater of low power consumption may be made.

Abstract: An apparatus and method for controlling the timing of control bursts in a wireless communications network maps the timing of control bursts on a multiframe by multiframe basis. In one implementation, a method of controlling base station transmissions in a wireless network in accordance with a multi-frame timing structure is provided. The method is defined as a succession of y frames, each frame including a succession of x time-slots, and includes allocating a frame/time-slot number pair to set the timing of a first-type control burst for a first multi-frame, and changing at least one of the (i) frame number and (ii) frame number and time-slot number of the frame/time-slot number pair for a second multi-frame so that the timing of the first-type control burst is different during the second multi-frame relative to the first multi-frame.

Abstract: Equipment and/or functions at a node (e.g., base station) of a cellular telecommunications network are turned off or put into sleep mode during periods of low traffic in order to reduce power consumption by the node. The equipment and/or functions are then turned back on again during periods of high traffic load in order to provide the required service to users. Exemplary actions which can be taken in order to save power during the power saving mode include, for example and without limitation: 1) switching off or putting to sleep one or more MCPAs, 2) turning off one or more carriers, 3) turning off one or more sectors with regard to a frequency, 4) turning off or putting to sleep at least a portion or part of one or more circuit boards, and/or 5) reducing fan speed based upon traffic load of the node. Any one or more of these or similar actions may be taken in order to enable the node to save power when its traffic load is at a low level. Power consumption can thus be reduced.

Abstract: A multiplication circuit 152 multiplies signals, which are subjected to variable directional transmission, by weighting factors with respect to the respective antennas 101 to 103, and outputs the resultant to combining circuits 155 to 157, respectively. The signals input to the combining circuit 155 are combined and radio modulated by a radio section 104, and transmitted from the antenna 101. Whereby, in a case where variable directional transmission is performed with respect to only some terminal apparatuses, signals, which are subjected to no variable directional transmission, can be transmitted after spreading them from the respective antennas of an array antenna.

Abstract: A system and method for GPRS MAC procedures to support delay-sensitive, real-time traffic is presented. The system comprises a mobile station able to transmit packets to and receive packets from a base station, where the base station is coupled to a General Packet Radio Service (GPRS) network, and where the GPRS network is coupled to a data network. In an uplink dynamic scheme, the base station receives an empty packet from the mobile station. The base station releases a bandwidth allocated to the mobile station if an implementation dependent time expires and further allocates a reduced portion of the bandwidth to the mobile station if a number of the empty packets are received or if a control packet requesting additional bandwidth is received by the base station. In an uplink fixed scheme, the base station allocates a fixed number of radio resources to the mobile station.
