  • Patent number: 7986669
    Abstract: To facilitate vertical handoff, a radio network will identify air interface protocols currently available for use by a wireless device and will then select one of the available air interface protocols based at least in part on the type of communication in which the device is currently engaged. The radio network may further take into consideration the current level of congestion under each available air interface protocol and may select an air interface protocol that has sufficient bandwidth available to support the type of communication in which the device is currently engaged. If the device is not currently operating under the selected air interface protocol, the radio network may then orchestrate a vertical handoff to the selected protocol.

  • Patent number: 7983716
    Abstract: In a radio access network, novel systems and methods reduce processing delay, and improve integration with IP networks, by separating user data from connection management and control data at a Node B or at a base station. The user data are routed to an IP (Internet Protocol) switch, whereas the connection management and control data are routed to a centralized radio network controller (RNC). Pursuant to a second embodiment of the invention, a centralized RNC provides improved radio resource management (RRM) functionality by handing all connection management and control data for a plurality of Node B's, thereby simplifying the switching of user data throughout the radio access network. Pursuant to a third embodiment of the invention, a smart IP switch is equipped to switch user data without core network (CN) involvement. Downlink user data are switched independently of uplink user data.

  • Patent number: 7983619
    Abstract: Intra-cell upstream data forwarding is utilized in a wireless network such as a wireless local area network. A network forwarding path is determined based on the signal strength of an access point signal received at client stations within the network, referred to as the OASS. In particular embodiments, a station that is either originating or forwarding a frame inserts its own OASS into the frame before transmitting it and a client station that receives a frame forwards it only if its own OASS exceeds the frame-enclosed OASS, illustratively by at least a predetermined amount.

  • Patent number: 7974642
    Abstract: Systems and methods for estimating a cell center location in a wireless communication system having all interface to a satellite positioning system (“SPS”) such as for example, a Geosynchronous Positioning System (“GPS”). The wireless communication system provides service to mobile stations within a cell, each mobile station includes a SPS receiver. Examples of the systems and methods for estimating a cell center location analyze the mobile station locations in a cell as a uniform distribution of mobile station locations and calculate a statistical measure characterizing the mobile station locations as a function of the mobile station locations. In one example, the statistical measure is a maximum likelihood mobile station location. In another example, the statistical measure is the mean mobile station location in the cell. The estimated cell center location may be used to approximate the location of the mobile station during a warm or cold restart of the SPS receiver part of the mobile station.

  • Patent number: 7974632
    Abstract: A method and a system for the localization of a mobile WLAN client, located within a WLAN network of multiple WLAN stations. Static reference points are ascertained by measuring field strengths of the WLAN stations at spatial coordinates, aided by WLAN client(s), and assignment of the measured field strengths to the spatial coordinates in terms of data records. Self-learning ascertainment of further dynamic reference points is obtained by measuring field strengths of the WLAN stations, aided by WLAN client(s) moving through the region of the network, and assignment of the measured field strengths in terms of data records to the respective spatial coordinates calculated for this purpose, in the database server. This may be done to localize a WLAN client by selecting a plurality of nearest matched data records of static and dynamic reference points whose subsequently calculated center of gravity corresponds to the estimated position of the WLAN client.

  • Patent number: 7974594
    Abstract: The present invention relates to a method for checking connectivity between a BSC (Base Station Controller) and an MSC (Mobile Switching Center), including: the MSC loopbacking a circuit and sending a connectivity check command to the BSC to instruct the BSC to perform the connectivity check; the BSC performing the connectivity check according to the connectivity check command; if the connectivity check is successful, the BSC sends a Connectivity Check Success identifier to the MSC to instruct the MSC to cancel the self-loop of the circuit; if the connectivity check fails, the BSC sends a Clear Request message to the MSC to release the communication connection and cancel the self-loop of the circuit. Embodiments of the present invention implement quick and convenient locating of connection errors by adding a Connectivity Check command in the messages for A-interface.

  • Patent number: 7974261
    Abstract: A wireless terminal using OFDM signaling supporting both terrestrial and satellite base station connectivity operates using conventional access probe signaling in a first mode of operation to establish a timing synchronized wireless link with a terrestrial base station. In a second mode of operation, used to establish a timing synchronized wireless link with a satellite base station, a slightly modified access protocol is employed. The round trip signaling time and timing ambiguity between a wireless terminal and a satellite base station is substantially greater than with a terrestrial base station. The modified access protocol uses coding of access probe signals to uniquely identify a superslot index within a beaconslot. The modified protocol uses multiple access probes with different timing offsets to further resolve timing ambiguity and allows the satellite base station access monitoring interval to remain small in duration.

  • Patent number: 7970348
    Abstract: A solution is disclosed for minimizing the amount of hardware and hardware accuracy requirements to simultaneously give the feature of both cell and narrow beams transmission, while enabling methods for capacity/coverage increase. The main property utilized by the present invention for maintaining cell-coverage pattern control, when radiating information in two simultaneous beams, is to use orthogonal polarization states for the two beams. The two orthogonal polarization states may for instance constitute linear polarization slanted at +45° and ?45°, respectively. The dedicated broadcast transmission needs to be conveyed defining the total cell coverage area. The total cell coverage area is matched by the coverage of the two fixed narrow-beams. The broadcast signal transmission is divided into two signal streams/paths, one for each of the two fixed narrow-beams (no coherency requirements existing between the two parallel signal streams/paths).
