Abstract: The combination of a narrowband application that provides a narrowband resource with broadband transport is enabled with a temporary connection across the broadband network between the narrowband resource device in a legacy switch and a Media Gateway within the broadband network. The Media Gateway has an established call connection to a called subscriber for the call. While providing the resource, the call connection for the call in the Media Gateway is broken, and the temporary connection is used.

Abstract: Transmitted signals from plurality of mobile terminals are received at one or more base stations in a Code Division Multiple Access system. The base stations send the received signals to a central processor in the form of complex signal sample streams. The central processor determines the correlations between the spreading codes used by the mobile terminals and combines the interference correlations with channel estimates to form an interference matrix. The central processor uses the interference matrix to process the received signals reduce the interference between signals from different mobile terminals.

Abstract: Processing of loop-back information returned by one or more mobile stations that are served by a wireless communication network permits the network to compensate its transmit signals for increased transmission efficiency and reduced signal interference at the mobile stations. Generally, the network forms one or more transmit signals as a combination of different signals intended for the different mobile stations, and remembers transmit information associated with these transmit signals. The mobile stations return loop-back signals to the network, which determines transmit signal compensation information by comparing loop-back information to memorized information. The mobile stations may loop-back samples from composite received signals, from processed received signal samples, or loop-back estimates.

Abstract: The invention comprises using beamforming antenna to coherently transmit an information signal to a receiver using two or more directional beams. In one embodiment, the phase and timing of the information signals carried by each directional beams are adjusted such that the signals arrive synchronously at the mobile terminal. Time synchronization may be obtained by delaying signals transmitted on selected directional beams to compensate for different propagation delays, or by preconditioning and filtering the signals using a channel coefficient matrix.

Abstract: An approach to facilitating positioning operations or other designated tasks performed by mobile stations within a wireless communication network enables individual mobile stations to request “free” or idle time if the mobile station's current operations do not provide sufficient background time to perform the required task. For example, the mobile station might be commanded to perform a positioning computation within a required time limit. If its background processing time is insufficient, the mobile station requests additional idle time from the network, which, if allocated by the network, is used by the mobile station to complete the required processing task. In an exemplary application, a GPRS-based network allocates additional “idle” blocks into the time-multiplexed multiframe structures supporting packet data communications with the mobile station.

Abstract: First and second classes of broadcast information, which have different repetitive rates, are transmitted in repetitive shared blocks of a Packet Broadcast Control Channel (PBCCH) of a General Packet Radio Service (GPRS) wireless communications system. The first class of broadcast information may be transmitted at a higher repetition rate in the shared blocks of the PBCCH than the second class of broadcast information. The same sequence of broadcast information of the first class may be transmitted in each instance of a shared block of the PBCCH along with successive portions of the broadcast information of the second class. The shared blocks may be evenly spaced apart within the PBCCH.

Abstract: The present invention provides a system for producing a packet delivery schedule, based on desired priority and weighting characterizations of the packet traffic. A number of prioritization schemes are systematically and efficiently reduce to reliable, repeatable schedules. The system accepts two sequences of inputs, based on desired message classification scales. The system begins counting through the sequences, based on their relationships to one another, to determine when to add a member of either scale to a schedule. The system may be designed to terminate the schedule after a fixed number of countings, or may be repeated iteratively as desired. Once a schedule is completed, the system may continue producing other schedules, utilizing different classification scales, until all classification scales have been comprehended. The resulting schedules are systematically combined to produce a single schedule comprehending all desired classification scales.

Abstract: A mobile communication system comprises a plurality of cells, with each cell including a network of microstations distributed more or less uniformly throughout the cell. A central controller connected to the network of microstations selects a group of microstations in the vicinity of the mobile terminal to transmit information to the mobile terminal. The selected microstations in the active set for a given mobile terminal is continuously updated as the mobile terminal moves through the network of microstations to form a virtual cell that follows the mobile terminal through the network. Transmission conflicts between two mobile terminals is avoided by inhibiting transmissions from an active microstation to at least one of the co-channel mobile terminals when a transmission conflict is detected.

Abstract: A mobile terminal and a base station subsystem may communicate by assigning a primary or control frequency to the cell in which the mobile terminal is located and using that control frequency to exchange control information between the mobile terminal and the base station subsystem. The exchange of control information in the cell is constrained to the primary or control frequency. In addition, a plurality of traffic frequencies may be assigned to the cell and used to exchange traffic information between the mobile terminal and the base station subsystem using coordinated frequency hopping. Multi-path fading experienced on diverse, non-contiguous traffic frequency bands may be uncorrelated between the respective bands. Consequently, a code-word carried over a plurality of non-contiguous frequencies may be more likely to experience random, uncorrelated fading, which may improve the signal to noise ratio (SNR) of the signal and, as a result, improve network performance.
