  • Patent number: 6836650
    Abstract: Methods, systems, and apparatuses for down-converting an electromagnetic (EM) signal by aliasing the EM signal are described herein. Briefly stated, such methods, systems, and apparatuses operate by receiving an EM signal and an aliasing signal having an aliasing rate. The EM signal is aliased according to the aliasing signal to down-convert the EM signal. The term aliasing, as used herein, refers to both down-converting an EM signal by under-sampling the EM signal at an aliasing rate, and down-converting an EM signal by transferring energy from the EM signal at the aliasing rate. In an embodiment, the EM signal is down-converted to an intermediate frequency (IF) signal. In another embodiment, the EM signal is down-converted to a demodulated baseband information signal. In another embodiment, the EM signal is a frequency modulated (FM) signal, which is down-converted to a non-FM signal, such as a phase modulated (PM) signal or an amplitude modulated (AM) signal.

  • Patent number: 6813493
    Abstract: A cellular mobile telephone system which can be used on board a vehicle enables conventional mobile telephones to be used on board an aircraft, for example. It includes a first transceiver on board the vehicle and connected to an antenna on the outside of the aircraft to set up an external radio link with a terrestrial mobile telephone network via a satellite. It further includes a second transceiver having an antenna inside the aircraft and connected to a base station controller. The second station and the base station controller have functions similar to those of a base station system in a conventional mobile telephone network, for example a GSM network. The base station controller is connected to the first transceiver. To prevent long signaling link set-up times, the base station controller includes software for setting up a signaling link between the aircraft and the terrestrial mobile telephone network in advance, as soon as at least one mobile telephone is switched on.

  • Patent number: 6782265
    Abstract: A method for determining the location of a mobile unit (MU) in a wireless communication system and presenting it to a remote party. The location of a remote MU is determined by comparing a snapshot of a predefined portion of the radio-frequency (RF) spectrum taken by the MU to a reference database containing multiple snapshots taken at various locations. The result of the comparison is used to determine if the MU is at a specific location. The comparison may be made in the MU, or at some other location situated remotely from the MU. In the latter case, sufficient information regarding the captured fingerprint is transmitted from the MU to the remote location. The database may be pre-compiled or generated on-line.

  • Patent number: 6748219
    Abstract: An apparatus and method for providing a dynamic mapping of channel numbers to physical frequencies for some cells of a cellular telephone system, for use in case of a cellular telephone system representing physical frequencies by channel numbers and providing a fixed mapping of channel numbers to physical frequencies. The method includes a step of providing an information element indicating the dynamic mapping, and is performed in a way that is compatible with an existing channel numbering space, thereby keeping unchanged any existing signaling messages. The method also provides for a change in a dynamic mapping: a duplicated mapping is broadcast in which two non-overlapping sets of channel numbers are both mapped at least in part to a same frequency block, the broadcasting being continued for a predetermined time assumed to be of sufficient extent that any mobile phones operating in the cells will have decoded the duplicated mapping.

  • Patent number: 6741872
    Abstract: The present invention consists of a method of authorizing access to a cellular mobile radio network from a simplified mobile telephone, simplified in particular in that it does not include a reader adapted to receive a subscriber identification module. According to the invention, access to the network is made possible in particular by a service initialization phase during which a subscriber to the network supplies to the network data representing a serial number specific to the simplified mobile telephone, for example its IMEI number, and data characteristic of each telephone number that can be called from the simplified mobile telephone, all of the data being stored in a data base of a server of the network in a private directory associated with the simplified mobile telephone.

  • Patent number: 6687510
    Abstract: A method and apparatus that determines how much power to allocate to each of a plurality of reverse link power control (RLPC) Channels to be transmitted from a base station, based upon data rate control (DRC) messages transmitted to the base station. Historical information is used to determine the quality of the Forward Link over which the RLPC is to be transmitted. If the history of the DRCs received indicates that the remote station to which the RLPC Channel is to be directed has not transmitted a DRC recently, then the base station allocates power to the RLPC Channels based upon information provided to the base station in DRCs that were received by the base station, but that were directed to other base stations. Accordingly, the base station can allocate power among the RLPC Channels without having received explicit information as to the quality of the Forward Link between the base station and every remote station intended to receive the information on the RLPC Channels.

  • Patent number: 6643513
    Abstract: Disclosed is a method for performing an inter-system handover. The method triggers the handover of a mobile station (100) from a UTRAN system to a GSM system by sending a HANDOVER FROM UTRAN COMMAND message from the UTRAN system. For the case where a HANDOVER COMMAND is sent transparently with the HANDOVER FROM UTRAN COMMAND, where the HANDOVER COMMAND has an information element set for indicating that ciphering is to be started, the method begins data ciphering immediately after handing over to the GSM system such that the first data frame transmitted by the mobile station in the GSM system is a ciphered data frame. For the case where there is a pre-existing UTRAN system ciphered data connection when the HANDOVER FROM UTRAN COMMAND message is received, the method continues without interruption the use of data ciphering with the data connection after handing over to the GSM system.

  • Patent number: 6628956
    Abstract: Delays on a common radio communications channel employed by plural mobile stations to communicate with a base station located in a corresponding geographical cell area are minimized by adapting transmission power based on traffic conditions. For lower traffic loads, a higher transmission power is permitted. For higher traffic loads, a lower power level is set. A transmit power level is determined using a desired signal ratio, such as a target CIR, a transmission path loss over the radio communications channel, and an interference value. One or more adaptive power parameters are also employed in that determination to adapt the open loop power control based on one or more current communications conditions and/or characteristics of the mobile station. For example, an adaptive power parameter may be a function of a current interference in a base station cell either alone or in combination with a current interference in one or more neighboring cells.

  • Patent number: 6615024
    Abstract: A method and apparatus for estimating the downlink signature for a remote transceiver which is part of a wireless communication system that includes a main transceiver for communicating with the remote transceiver. The main transceiver includes an array of transmit antenna elements. The method uses the remote transceiver for receiving signals when the main transceiver transmits downlink calibration signals. When the main transceiver also has a receive antenna array, the remote transceiver can transmit uplink calibration signals to the main transceiver for determining an uplink signature. The downlink and uplink signatures are used to determine a calibration function to account for differences in the apparatus chains that include the antenna elements of the arrays, and that enable downlink smart antenna processing weights to be determined from uplink smart antenna processing weights when the main transceiver includes means for smart antenna processing according to weights.
