Abstract: Disclosed herein is a method and apparatus for providing a pilot-beacon on behalf of one or more base stations, such as one or more femtocells. A pilot-beacon transmitter, separate from the base stations, determines the locations of coverage areas of the base stations and then dynamically configures a pilot-beacon radiation pattern to encompass (approximately) the determined coverage areas. That way, a mobile station may detect the pilot beacon and initiate scanning of coverage provided by the base stations. Optimally, the method can be used to provide a pilot beacon for femtocells, thereby avoiding the need for the femtocells to include pilot beacon transmission functions and thus possibly decreasing the cost of the femtocells. The pilot-beacon transmitter or another entity may also be configured to receive and forward GPS signals to the base stations, possibly offsetting GPS timing based on measured delays for communication with the base stations.

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.

Abstract: A mechanism for providing a wireless backhaul connection between a remote base transceiver station (BTS) and core radio access network (RAN) equipment such as a base station controller (BSC) for instance. The remote BTS will be provided with wireless server logic, such as a cell site modem (CSM), the RAN equipment will be provided with wireless client logic, such as a mobile station modem (MSM), and the wireless server logic of the remote BTS will be arranged to serve the wireless client logic of the RAN equipment with a packet-data connection for use to carry backhaul communications between the remote BTS and the RAN equipment. Advantageously, limited air interface resources of the core RAN equipment can thus be preserved for directly serving wireless client devices, as limited air interface resources of the wireless client logic at the remote BTS are instead (or in addition) allocated for the backhaul communication.

Abstract: Methods and systems are provided for dynamic allocation of carrier frequencies in wireless wide area networks (WWANs). A first base station among a plurality of base stations in a WWAN determines that a level of load in a wireless coverage area exceeds a load threshold, and responsively (i) obtains a first keycode from a keycode library, wherein the first keycode then becomes unavailable to the other base stations of the plurality of base stations, (ii) identifies a carrier frequency, and (iii) uses the first keycode to activate the identified carrier frequency in the wireless coverage area.

Abstract: A method and system for bridging third parties into calls. When a subscriber places a call to a designated number, such as 9-1-1 for instance, the network will automatically connect the call to a conference bridge and to the called party. Further, the network will automatically generate and send to a designated third party contact person an alert message that will invite the contact person to call into the conference bridge, so that the contact person can listen to the call. Advantageously, the invention may thus enable a close friend or relative to more quickly learn about an emergency being reported by the subscriber.

Abstract: Methods and systems for selecting data rates are described in a wireless network. The distance between a client and a base station serving the client device is determined. Based on that distance, a minimum threshold data rate is selected such that a larger distance corresponds to a higher minimum threshold data rate and a smaller distance corresponds to a smaller minimum threshold data rate. An actual data rate, not less than the minimum threshold data rate, is then selected, and signals are transmitted between the client device and the base station at the actual data rate. The actual data rate may be increased if there exists unused available bandwidth in the network. Events such as a change in distance or a timer expiring may result in a recalculation of the minimum threshold data rate.

Abstract: Assigning CDMA channel codes in a multiple beam zone sector such that they may be reused within the same sector. In an exemplary embodiment, the method includes configuring directional antennas in a cell sector to provide multiple beam zones in a cell sector and assigning channel codes for use within the beam zones such that each channel code is assigned for use in only one beam zone of any set of three consecutive beam zones in the cell sector. This effectively reduces the inter-user interference by ensuring at least two intervening beam zones are located between zones that are using the same channel codes. The channel codes may be Walsh codes or quasi-orthogonal functions (QOFs).

Abstract: A system and method are provided for using differentiated telephone numbers to determine whether to perform a vocoder bypass. In an exemplary embodiment, a mobile station may call a terminating node. An intermediate entity may search an identifier of the terminating node for a predetermined aspect. If the predetermined aspect is found, the terminating node may be a mobile station, and the intermediate entity may perform a vocoder bypass. If the predetermined aspect is not found, the terminating node may be a non-mobile station, and the intermediate entity may perform vocoding.

Abstract: Presently disclosed is a method for reducing interference in a wireless distributed antenna systems. In an embodiment, interference is reduced by selectively placing a first wireless remote unit in a reduced signal interference mode. A controller sends a signal, such as a reverse link power-down signal, to the first remote unit after detecting less than a threshold incoming signal strength at the first remote unit. In an alternative embodiment, the controller requests that a given remote unit switch to the reduced signal interference mode when the controller is receiving signals from a mobile station through at least two different remote units.

Abstract: A wireless telecommunications network that uses a first frequency spectrum for wireless communications in a plurality of generally contiguous wireless coverage areas also has available a second frequency spectrum for wireless communications in a high-traffic wireless coverage area. Mobile stations in the high-traffic wireless coverage area are classified as either static or dynamic based on determinations of their speeds. The wireless telecommunications network uses the first frequency spectrum for wireless communications with dynamic mobile stations in the high-traffic wireless coverage area and uses the second frequency spectrum for wireless communications with static mobile station in the high-traffic wireless coverage area. The wireless telecommunications network may instruct the mobile stations in the high-traffic coverage area to use the appropriate frequency spectrum.

Abstract: A method of communicating with a mobile station. The method includes receiving forward link signals from a central base station at a remote base station and transmitting the forward link signals from the remote base station to the mobile station. The method also includes receiving reverse link signals from the mobile station at the remote base station and transmitting the reverse link signals from the remote base station to the central base station. The method further includes cooperatively adjusting a transmission power level for communication between the mobile station and the remote base station.

Abstract: A wireless signal repeater will function to boost the strength of signals being communicated wirelessly between a base station and a mobile station. At the same time, however, the wireless signal repeater will read control channel messages transmitted by the base station and will obtain from the messages an indication of outside temperature and an indication of local time. The repeater will then display the outside temperature and local time information for viewing by a user. Advantageously, the repeater will thus become a more functional object in the eyes of the average lay-person, rather than functioning merely to boost wireless signal levels.

Abstract: A method and system for defining additional spread spectrum channels within a coverage area already served by an existing wireless network. A first spread spectrum channel may be defined by a first range of frequencies. A second spread spectrum channel may be defined by a second range of frequencies. A portion of the first range of frequencies may overlap with a portion of the second range of frequencies. The overlap may be such that the first spread spectrum channel and the second spread spectrum channel may carry signals that minimally interfere with each other.

Abstract: A wireless repeater and method for managing air interface communications is provided. A repeater may include a donor antenna, a coverage antenna, a mobile station modem, a processor, and data storage. The donor antenna will receive a plurality of air interface beams on the forward link from a radio access network. The coverage antenna will pass each forward link beam received to a mobile station being served by the repeater. Further, the donor antenna will pass each forward link air interface beam to the MSM, where the MSM will apply a rake receiver to identify a signal characteristic of the forward link of each beam received, and the processor will record in the data storage the signal characteristic corresponding to each beam. Given this data, the repeater will select an air interface beam with the most preferable signal characteristic, and will keep only this beam active for reverse link communications.
