    Abstract: PROBLEM TO BE SOLVED: To reduce interference caused by concurrent broadcast transmissions from multiple transmitters.SOLUTION: Synchronized broadcast transmits the same broadcast content using the same waveform from multiple transmitters. The transmitters each apply the same spreading code for broadcast transmissions. In a spread-spectrum communication system having a time division multiplexed forward link, a synchronized broadcast transmission is inserted into a broadcast slot. An Orthogonal Frequency Divisional Multiplex (OFDM) waveform is used for the synchronized broadcast transmission. An OFDM receiver is then used to process the received synchronized broadcast transmission. A broadcast Pseudo-random Noise (PN) code is used for use by multiple transmitters. An equalizer is then used to estimate the synchronized broadcast transmission.

    Abstract: PROBLEM TO BE SOLVED: To provide a method of transmitting, by synchronized broadcast, the same broadcast content using the same waveform from multiple transmitters.SOLUTION: Transmitters each apply the same spreading code for broadcast transmissions. In a spread-spectrum communication system having a time division multiplexed forward link, a synchronized broadcast transmission is inserted into a broadcast slot. One embodiment employs an Orthogonal Frequency Divisional Multiplex (OFDM) waveform for the synchronized broadcast transmission. An OFDM receiver is then used to process the received synchronized broadcast transmission. An alternate embodiment implements a broadcast Pseudo-random Noise (PN) code for use by multiple transmitters. An equalizer is then employed to estimate the synchronized broadcast transmission.

    Abstract: PROBLEM TO BE SOLVED: To provide a communication system capable of completing soft hand-off, even when a communication link between an active base station and a mobile station deteriorates before the mobile station receives a handoff direction message. SOLUTION: The mobile station maintains a list of communicating base stations X, referred to as an "Active Set". Further, the mobile station maintains another list of base stations Y close to the base stations X in the Active Set. The list is referred to as a "Neighbor Set". A memory in the mobile station includes information which enables the mobile station to demodulate information transmitted from the base stations Y in the neighboring set. When a base station Y is included in a pilot strength measurement message (PSMM), the mobile station places the base station Y in the active set. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for monitoring link activity to prevent system deadlock in a dispatch system. SOLUTION: A method and apparatus to prevent system deadlock in a dispatch system by monitoring link activity is disclosed. The dispatch system comprises of a set of remote units 10, 20, 22 which communicate with each other by broadcasting one at a time to the group. A remote unit 10 communicates with the other remote units through at least one base station 44. A communications manager 40 grants a remote unit 10 to be the exclusive system talker upon request through the base station servicing the requesting remote unit 44. The base station 44 monitors a series of data from the remote unit designated as the system talker 10 to detect voice activity. The base station 44 sends a surrogate request to the communications manager 40 to relinquish the system talker privilege if the voice activity falls below a predetermined threshold.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus of providing bit count integrity and synchronous data transfer over a channel which does not preserve synchronization.
    SOLUTION: A terminal equipment unit produces a constant rate bit stream which is provided to a communication unit. The communication unit produces: a first data frame comprising a first set of bits from the constant rate bit stream and a first length field, a second data frame comprising a second set of bits from the constant rate bit stream and a second length field, and a third data frame comprising a third set of bits from the constant rate bit stream and a third length field. The first, second and third data frames are transmitted to a base station, which places the first set of bits from the first frame into a queue. A set of fill bits equal to the maximum number of bits contained in any frame is then placed into the queue.

    Abstract: PROBLEM TO BE SOLVED: To provide a system and method for minimizing data bottlenecks in low data rate networks (LDRNs) that communicate facsimile transmissions. SOLUTION: An LDRN is a facsimile network having a transmission data rate less than the data relate of the FAX machines serviced by the network. The system and method can be implemented in any type of LDRN, including analog and digital wired LDRNs, as well as analog and digital wireless LDRNs (cellular networks, for example). The system and method involve processing the facsimile transmissions in order to make the data rates of the LDRN and the FAX machines compatible. Thus, any potential facsimile data bottlenecks that may occur in the LDRN due to its slower data rate can be minimized. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a method for enabling femtocell functionality to devices within a communications network.SOLUTION: A non-femto enabled device and/or a femto enabled device can communicate with a femto enabled device in the same geographical area for femto-enabled peer-to-peer communication. Two non-femto enabled devices can be provided with femto functionality through utilization of a femto enabled device, which operates as a hub between the two devices. In a further aspect, a determination is made as to whether a connection of a device is handed over to a femto enabled device if both devices are extremely proximate to each other. Other aspects relate to enhanced position determination, adaptive coverage enhancement, local mobile networks, open access femtocells without a backhaul, and local broadcast of media though utilization of femto enabled devices.
