  • Patent number: 9414422
    Abstract: Systems and methods are provided for using geo-fencing techniques to assist in detecting mobile communication devices that are close enough to support direct communication. A mobile communication device can periodically report its geo-fence area to a central server. The server can determine whether to ask the communication device to report more precise geographic information (e.g., GPS information) based on whether another communication device eligible for direct communication is within the same geo-fence area.

  • Patent number: 9407559
    Abstract: A method discovers routes for forwarding packets from source nodes (sources) to sink nodes (sinks) in a wireless network, wherein some neighboring sources act as relay nodes. Each source measures a rate of receiving control messages from each neighboring node. Then, the data packets are forwarded from a particular source to the sink via the neighboring nodes having a lowest rate.

  • Patent number: 9402218
    Abstract: Systems, methods, and computer-readable media for prioritizing a handover from an LTE network to a legacy network are provided. The method includes receiving, at a management component, a message from a mobile device. The message communicates a capability type associated with the mobile device. Based, in part, on this capability type, the management component assigns a priority to the mobile device. According to the assigned priority, the management component prioritizes the handover of the mobile device from the LTE network to the legacy network. This method reduces the latency for network handovers of mobile devices that are assigned a high priority.

  • Patent number: 9357416
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which channel quality indicator (CQI) requirements for reporting a CQI are received, whether the CQI is to be reported periodically is determined based on the CQI requirements, and a wake-up time based on the determination is scheduled. CQI reporting requirements, such as CQI scheduling information may be used to plan a UE discontinuous reception (DRX) wake-up time and adaptively shorten a duration the UE is awake when transmission of a CQI report is not required at a first subframe of a DRX on-duration. The shorter UE awake duration results in reduced power consumption.

  • Patent number: 9320017
    Abstract: UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8-n) bits, where n=the number of bits in C/T field.

  • Patent number: 9313488
    Abstract: Disclosed is a system and method of controlling a video decoder, including a reviewing channel data representing coded video data generated by an encoder to identify parameters of a hypothetical reference decoder (HRD) used by the encoder during coding operations. A parameter representing an exit data rate requirement of a coded picture buffer (CPB) of the HRD is compared against exit rate performance of the video decoder. If the exit rate performance of the video coder matches the exit rate requirement of the HRD, the coded video data is decoded, otherwise, a certain decoding degradation scheme can be applied, including disabling decoder from decoding the coded video data.

  • Patent number: 9307427
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving packet communication in a broadcast D2D communication system. In an example, a communications device is equipped to receive a first packet during a first timeslot from a broadcast transmitter, measure a power level of a NACK received during the first timeslot, receive the first packet during a second timeslot, and determine whether to transmit the first packet during the second timeslot based on the measured power level of the NACK. In such an aspect in which the communications device determines that the measured power level of the NACK is above a threshold power level, the communications device may act as a relay and transmit the first packet during the second timeslot.

  • Patent number: 9300583
    Abstract: A router in an embodiment associates a corresponding digital code of a set of digital codes to a respective portion of a network address of set of network addresses used in routing information. The routing information is stored in a memory with each digital code substituted for the respective portion of the network address. Memory reduction is obtained as a result. In an embodiment implemented in the context of IPv6 having a prefix and a host identifier for each network address, the portion of a network address corresponds to the prefix. The routing information is stored in the form of a prefix table and topology information. The prefix table stores a mapping of each digital code to a corresponding prefix. The topology information indicates a manner in which each host system and router are connected to each other. Packets are forwarded by examining such routing information.

  • Patent number: 9276833
    Abstract: In one embodiment, an ingress network virtualization edge (NVE) in a computer network generates an echo packet, and sets an indication in the echo packet that the echo packet is for overlay path validation. In addition, the ingress NVE sets a message type of the echo packet to a generic echo request, and includes virtualization network (VN) context information within the echo packet. Once setting a destination address of the echo packet as an egress NVE address and including an indication to the egress NVE that the echo packet is an operations, administration, and management (OAM) message, the ingress NVE may then send the echo packet toward the egress NVE (e.g., to validate the VN context information and/or to reveal multipath traces).
