Abstract: In a communications system including a set of base stations (14, 16, 18, 20) in communication with a remote unit (10), a technique is provided for centrally controlling transmission power. In accordance with this technique, a reverse link frame of data is first received from the remote unit (10) at each of the set of base stations (14, 16, 18, 20). The base stations (14, 16, 18, 20) determine a frame quality indication corresponding to the received reverse link frame of data and transmit the frame quality indication to a system controller (22, 24). The system controller (22, 24) then calculates, based on the frame quality indication from each of the set of base stations (14, 16, 18, 20), an aggregated frame quality indication corresponding to the received reverse link frame of data, and based on the aggregated frame quality indication calculates an absolute reverse threshold value. The absolute reverse threshold value is then provided to each of the set of base stations (14, 16, 18, 20), and each of the set of base stations (14, 16, 18, 20) provides a power control command for the remote unit (10) based on a comparison between the frame quality indication determined at the base station and the absolute reverse threshold value.

Abstract: A method and system determines whether the receiving subscriber unit is also part of a digital wireless telephone system that has compatible vocoding capability. If so, vocoded data is converted into tones that are introduced into a wire-based telephone system for routing to the appropriate receiving digital wireless telephone system. When these tones are received by the receiving digital wireless telephone system, the vocoded data is regenerated based on the tones and then transmitted to the receiving subscriber unit. If the originating and receiving wireless subscriber units are part of the same digital wireless telephone system, the steps of conversion to tones and introduction into the wire-based telephone system may be omitted, and the vocoded data is passed between the two digital wireless telephone systems via an all-digital connection such as an ATM packet network or a wire-based telephone connection where the integrity of digital information is assured.

Abstract: A method and apparatus of determining signal strength, regardless of the signal data rate, in a receiver receiving signals from a variable rate transmitter. The incoming signal is comprised of a series of frames. Each frame is comprised of a number of power control groups containing data. The number of the power control groups containing data within each frame is dependent on the unknown data rate. The position of the power control groups within the frame is a pseudorandom. The signal strength of an incoming signal of unknown data rate is determined based upon an active set of power control groups within a frame. The active set of power control groups contain data independent of the unknown data rate. This signal strength information may be used to indicate that the signal strength is sufficient to perform further signal processing.

Abstract: In a receiver having a plurality of demodulation elements, a method of assigning the plurality of demodulation element so a set of available signals. A first method emphasizes diversity of transmitting devices so that power control is optimal. A second method emphasizes the maximum signal strength available to produce aggregate maximum signal strength. Both methods control the number of reassignments so that excessive data is not lost during the reassignment process. The apparatus comprises the plurality of demodulation elements, at least one searcher element, and a controller.

Abstract: A method and apparatus for controlling the data rates for communications to and from a base station (2) and a plurality of remote users (4). The usage of the communications resource whether the forward link resource, from base station (2) to remote users (4), or reverse link resource, from remote users (4) to base station (2), is compared. The measured usage value is compared against at least one predetermined threshold value and the data rates of communications or a subset of communications on said communications resource is modified in accordance with said comparisons.

Abstract: Methods and apparatus for proxying of devices and services using overlay networks. A method for operating a proxy includes obtaining meta-data associated with at least one of a device and a service, generating a searchable index of the meta-data, and publishing the searchable index on the overlay network as at least one of a distributed index and a centralized index. Another method includes receiving a request from a device or a service using a non overlay protocol to receive at least one of data and services from the overlay network, searching an index of meta-data on the overlay network based on the request, identifying a node associated with the at least one of data and services based on the index, establishing a direct connection with the node, and obtaining the at least one of data and services using the direct connection.

Abstract: An integrated search processor (128) used in a modem (110) for a spread spectrum communications system buffers in a buffer (172) received signals samples and utilizes a time sliced transform processor (120) operating on successive offsets from the buffer (172). The search processor (128) autonomously steps through a search as configured by a microprocessor (136) specified search parameter set, which can include the group of antennas to search over, the starting offset and width of the search window to search over, and the number of Walsh symbols to accumulate results at each offset. The search processor (128) calculates the correlation energy at each offset, and presents a summary report of the best paths found in the search to use for demodulation element (122) reassignment. The search is done in a linar fashion independent of the probability that a signal being searched for was transmitted at any given time.

Abstract: A method and apparatus for operating a cellular telephone system that supports performing an inter-system soft handoff is described. A subscriber unit generates a pilot strength measurement report when the pilot channel from a base station is detected. When a base station controller receiving the pilot strength measurement report determines that the base station is part of a second cellular telephone system, a inter-system soft handoff request is generated. An admission control subsystem receives the inter-system soft handoff and either grants or denies the request base on the traffic level with the second cellular telephone system. In a preferred embodiment of the invention, the traffic level is determined based on link load messages received periodically by the admission control subsystem that are generated by an interface port coupled to an interconnect between the first cellular telephone system and the second cellular telephone system. The link load message include peak queue length and average frame rate information.
