  • Patent number: 9730131
    Abstract: A method and system for managing handover from a first radio access network to second radio access network is provided. The method includes receiving information associated with one or more neighboring cells from a User Equipment (UE). The information associated with the one or more neighboring cell is measurement reports. Thereafter, the method deciding to perform Handover (HO) based on the measurement reports for the UE from the first radio access network to the second radio access network. Further, the method identifies a target cell from the one or more neighboring cells. The method then determines target cell capabilities. Thereby, the method sends at least one of a handover required message and a relocation required message along with the target cell capabilities to a core network element. The core network element then manages voice bearers and non-voice bearers based on the target cell capabilities.

  • Patent number: 9716536
    Abstract: The data are communicated from a transmitter to a receiver in a wireless communications network. Data symbols are modulated using a coded modulation to produce modulated symbols and the modulated symbols are precoded using a precoder matrix to produce precoded symbols. The precoder matrix is formed using a rotation matrix including phase angles for at least some elements of the rotation matrix with values determined according to a parametric function of indices of the elements storing the phase angles. Next, the data packets are formed using the precoded symbols and the data packets are transmitted over the wireless network. Multi-stage parametric phase precoding provides full-diversity and full-rate transmissions by using fast-transformable unitary matrices and deterministic diagonal phase rotation, whose phase angles are pre-determined to minimize the union bound for time-selective and frequency-selective fading channels.

  • Patent number: 9674313
    Abstract: Embodiments of the invention relate to payload storage format for storing data in support of an aggregation function. As an input is subject to aggregation, the input is evaluated to ascertain a payload format for the aggregation. It is understood that there is more than one payload format. An evaluation of the aggregation key is a factor in the initial payload format. If the key is an addition to an existing aggregation, the evaluation considers changing the format of the payload to address processing and/or memory efficiency for the aggregation. The evaluation and the format change takes place dynamically so that the aggregation may continue.

  • Patent number: 9668206
    Abstract: Techniques for multiplexing and transmitting multiple data streams are described. Transmission of the multiple data streams occurs in “super-frames”. Each super-frame has a predetermined time duration and is further divided into multiple (e.g., four) frames. Each data block for each data stream is outer encoded to generate a corresponding code block. Each code block is partitioned into multiple subblocks, and each data packet in each code block is inner encoded and modulated to generate modulation symbols for the packet. The multiple subblocks for each code block are transmitted in the multiple frames of the same super-frame, one subblock per frame. Each data stream is allocated a number of transmission units in each super-frame and is assigned specific transmission units to achieve efficient packing. A wireless device can select and receive individual data streams.

  • Patent number: 9654335
    Abstract: A network management method comprises configuring network domains (NDs) of a host communications network (HCN). Each ND provides a virtual network (VN) provisioned within the HCN for an enterprise customer, which forms a virtual communications subnetwork from which the enterprise customer provisions communications services. The HCN provides bandwidth over outroute and inroute channels of the HCN for the VNs. Outroute partitions are configured via outroute channels of the HCN and inroute partitions are configured via inroute channel groups configured within inroute channels of the HCN. Each outroute partition supports outroute bandwidth and each inroute partition supports inroute bandwidth. The outroute capacity partitions and the inroute capacity partitions are allocated to VNs to provide outroute and inroute capacity to the VN. Operator classifications are configured within the ND associated with the VC.

  • Patent number: 9628997
    Abstract: A carrier sense unit (121) of a PHS base station (12) periodically carrier-senses nearby radio waves and monitors whether radio wave interferences with a communication channel to be used for communication with a PHS terminal (13) is occurring. A communication channel management unit (122) ranks communication channels to be used for communication with the PHS terminal (13) based on a monitoring result by the carrier sense unit (121). When a request for acquiring or a request for switching to a communication channel to be used for communication with the PHS terminal (13) is made, a communication channel switching control unit (123) preferentially selects and allocates a communication channel ranked high as a communication channel where radio wave interference is not occurring from among usable communication channels ranked and managed by the communication channel management unit (122).

  • Patent number: 9590690
    Abstract: Disclosed herein are methods and systems for canceling a blocking signal to obtain a desired signal. An example process includes receiving both a blocking signal and a set of blocking bits corresponding to a demodulation of the blocking signal. A remodulated blocking signal is generated by modulating the received set of blocking bits. The remodulated blocking signal is passed through a blocking-band bandpass filter to generate an estimated blocking signal, and is also passed through a desired-band bandpass filter to generate an unconditioned reference signal. One or more signal-parameter differences between the blocking signal and the estimated blocking signal are identified, and one or more signal compensations are accordingly applied to the unconditioned reference signal to generate a conditioned reference signal, which is then output to a blocking-signal-canceling system.
