  • Patent number: 8804525
    Abstract: A method and a device for network traffic control comprising the following steps: detecting actual downlink traffic of a network device; calculating an error e between the actual downlink traffic and predetermined downlink traffic; performing a calculation on the error to obtain PID output according to a PID control formula; calculating scaling of upstream traffic according to the calculated PID output and the downlink traffic; and regulating an upstream traffic threshold according to the scaling. The upstream traffic is increased or reduced in accordance with the actual downlink traffic be means of the correlated regulation and dynamic control of the upstream traffic and the downlink traffic of the network device. As such, traffic control is realized in those applications (e.g. UDP traffic such as P2P streaming media) which themselves lack the traffic control mechanism, and it is possible to make the best of network bandwidth as well.

  • Patent number: 8797989
    Abstract: A method for determining a proper preamble allocation mode is provided. The method is applicable to a base station communication with a number of human to human UEs and machine to machine UEs. The base station collects information from different types of UEs to figure out arrival rates for human to human type random access attempts and machine to machine type random access attempts. The base station selects one allocation mode out of two different allocation modes. In one mode, random access preambles are dedicatedly allocated to machine to machine type UES. In the other mode, preambles are commonly allocated to different types of UEs. The base station indicates the selected allocation mode by using system information block such as SIB2.

  • Patent number: 8787187
    Abstract: A communication device transmits a plurality of measurement packets for identifying an available bandwidth to another communication device connected via a network, using bandwidths in the measurement bandwidth range. The communication device then determines whether the available bandwidth is included in the measurement bandwidth range. In a case where the available bandwidth is not included in the measurement bandwidth range, the communication device determines whether the available bandwidth is located on a narrowband side or on a wideband side with respect to the measurement bandwidth range, and determines a bandwidth shift amount based on an amount of change. The communication device updates the measurement bandwidth range by shifting one of the lower bandwidth and the upper bandwidth based on the bandwidth shift amount.

  • Patent number: 8654726
    Abstract: The present invention relates to an uplink/downlink scheduling in a mobile communication system and signal transmitting/receiving scheme using the same, and more particularly a method and apparatus for a user equipment to transmit and receive signals. Each user equipment manages an interferential base station list to meet the process rate requirements. If a specific user equipment receives a first step scheduling signal including contention number information, base stations in a base station list managed by the corresponding user equipment are regarded as having real inter-cell interference links. Hence, in order for a base station having a highest priority to enable a resource assignment in a corresponding scheduling stage, a silencing signal for requesting a resource assignment prohibition is transmitted to the rest of the base stations.

  • Patent number: 8644195
    Abstract: A ring-based network and a construction method thereof, comprising a plurality of nodes and a plurality of links. In an initial status, each node compares each first link-up packet and fills a priority value in the first link-up packet with the higher priority value to form a second link-up packet. The priority value of each node and the highest priority value of each adjacent node recorded in each node are compared with each second link-up packet. When the priority value of the node and the highest priority values of adjacent nodes recorded in the node are smaller than the second link-up packet, the ring port of the node is situated at a forward status. According to the forward status or a blocked status of the ring port, these links form a plurality of forward links and a blocked link respectively.

  • Patent number: 8638752
    Abstract: When a mobile device moves from a first QoS-aware system to a second QoS-aware system, QoS flows may or may not be moved properly. To deal with this, the mobile device requests de-allocation of flows in the second QoS-aware system, and then initiates reservation of flows in the second QoS-aware system. After this, the mobile device will know for certain which QoS flows exist in the second QoS-aware system and can behave accordingly.

  • Patent number: 8606924
    Abstract: In a cloud computing environment customers of the cloud believe they have instantaneous access to unlimited resources however to satisfy this with finite resources there are times when resources could have to be acquired from an external cloud with potentially different security capabilities and performance capabilities. A method and system are therefore disclosed to reduce cost incurred while scaling to an external cloud to meet short term demand and to take into account security and performance requirements of customers. The proposed method and system provide automation and prediction capabilities to help with the decision of growing cloud resources or temporarily becoming a hybrid cloud. By “pre-bursting” the cloud in anticipation of a cloud burst the growth in resources can be predicted and performed (with security and load balancing in mind) prior to actual cloud consumer requests.
