  • Patent number: 10887827
    Abstract: Example communication message sending methods and apparatus based on backoff duration are described. One example method includes that a terminal device sends an access request to a cell to which the terminal device belongs. The terminal device monitors a downlink control channel, and receives an access response message based on scheduling information on the downlink control channel. If the access response message carries a backoff access identifier, the terminal device determines a backoff parameter corresponding to the backoff access identifier in the access response message based on a correspondence that is pre-stored and that is between the backoff access identifier and the backoff parameter. The terminal device determines backoff duration based on the backoff parameter and an access resource interval period corresponding to the terminal device, and sends an access request to the cell after the backoff duration.

    Abstract: A multiple-persona system and method is described, wherein a UE (user equipment) is able to connect to two different networks simultaneously. In a multiple-persona system, one of the personas may have a higher significance than the other persona. For example, a connection to a work network may be prioritized over connection to a home network. In such a situation, it may be desirable to have applications running on the work network have priority over applications running on the home network. Such a method and system may operate independently of the eNodeB or have the eNodeB actively controlling the priority among the personas.

  • Patent number: 8913597
    Abstract: A cyclic prioritized multiple access method is disclosed which includes Fixed Deterministic Post-Backoff. Fixed deterministic post-backoff reduces conflicts between access points of overlapping cells. Contention-free sessions can be generated, one from each overlapping cell. Each active access point engages in a fixed deterministic post-backoff. A fixed deterministic backoff delay (Bkoff times a fixed number of idle time slots) is used by all access points, with the value of Bkoff being greater than the number of overlapping cells. The Bkoff should be large enough to enable the traffic that needs to be accommodated by the channel. Each access point has a backoff timer that is counted down using the shortest interframe space possible. A contention-free session is initiated when the backoff timer expires, and it is then reset to the value of Bkoff to start a new cycle.

  • Patent number: 8867345
    Abstract: An intelligent electronic device segregates urgent data frames from non-urgent data frames on reception so that the urgent data frames may be handled with greater priority. A switching device is disposed between an external network interface and multiple internal network ports. Based on a network data type indicia, urgent data frames are routed to one of the ports, and non-urgent data frames are routed to another port. A processor coupled to the internal network ports handles urgent data frames before handling any non-urgent data frames.

  • Patent number: 8817628
    Abstract: In a wireless system of one embodiment, a first wireless device includes: a first transmitter which transmits an end-of-transmission notification; and a first receiver which receives a change request signal sent from a second wireless device receiving the end-of-transmission notification. The second wireless device includes: a second receiver which receives the end-of-transmission notification; and a second transmitter which transmits a change request signal when the end-of-transmission notification is received. The first transmitter transmits a signal at a longer interval after the first receiver receives the change request signal, and the second transmitter transmits a signal at a shorter interval after the second transmitter transmits the change request signal.

  • Patent number: 8787368
    Abstract: A crossbar switch with primary and secondary pickers is described herein. The crossbar switch includes a crossbar switch command scheduler that schedules commands that are to be routed across the crossbar from multiple source ports to multiple destination ports. The crossbar switch command scheduler uses primary and secondary pickers to schedule two commands per clock cycle. The crossbar switch may also include a dedicated response bus, a general purpose bus and a dedicated command bus. A system request interface may include dedicated command and data packet buffers to work with the primary and secondary pickers.

  • Patent number: 8780815
    Abstract: A wireless base station monitors a state of reception in a common transmission region (channel) in a wireless frame common to a plurality of wireless terminals, and controls allocation of a transmission region in the wireless frame to be used for transmission by the wireless terminals on the basis of a result of the monitoring and information about priority set to each of the plural wireless terminals. The wireless resource can be preferentially allocated to a wireless terminal of a user having high priority even when the common communication region used to obtain permission to send a bandwidth request is congested.

  • Patent number: 8773998
    Abstract: A technique that allows existing reservations to be partially preempted by higher-priority reservations. An intermediate node receives a request to reserve resources for the higher-priority reservation. The higher priority entitles the reservation to acquire resources allocated to existing lower priority reservations, if necessary. If sufficient unallocated resources are not available on the preempting system to accommodate the higher-priority reservation, an error message is generated and forwarded by the intermediate node towards a receiver associated with the reservation that is to be partially preempted. The error message contains an error code and an amount of resources available on the intermediate node. The receiver processes the error message including selecting a reservation to be torn down, tearing down the selected reservation and re-reserving resources for remaining reservations, as necessary.

  • Patent number: 8699333
    Abstract: In one embodiment, a device in a shared-media communication network determines a priority of a packet to be queued at the device, and based on the priority determines a length of time the packet is allowed to be queued before being successfully transmitted. After attempting to successfully transmit the queued packet within the shared-media communication network, in response to reaching a threshold amount of the length of time without having successfully transmitted the queued packet, the device may transmit a “shaping” request to one or more reachable neighbors in the shared-media communication network. Specifically, the shaping request is for a temporary reduction in bandwidth utilization by the reachable neighbors for traffic having a comparatively lesser priority than the priority of the packet.
