  • Data routing method and related apparatus
    Patent number: 12250149
    Abstract: Data routing with a forwarding process of service data can avoid problems of offline nodes. The forwarding process for data routing can also improve the fault tolerance and service data can be quickly transmitted to a corresponding data pool. Using consensus nodes and a target data pool with routing and forwarding tables along with subtrees from a trie tree can improve the routing. Subtrees may be obtained by splitting the trie tree from a root node by using a first leaf node as a benchmark, which correspondingly represents a data pool of the consensus node. The routing and forwarding table is configured to record addresses of data pools correspondingly represented by a preset quantity of leaf nodes in a corresponding subtree.

  • System and method for managing communications for two networks in a communication device
    Patent number: 9749878
    Abstract: A system, method and device for adjusting communication parameters for networks communicating with a communication device are provided. The method comprises: when the communication device is linked to a first communication network and a second communication network, comparing a strength of received signals from the second network against a threshold; and when the strength of the received signals is less than the threshold, adjusting a network parameter of signals received from the second communication network by the communication device.

  • Mitigating interference with wireless communications
    Patent number: 9538436
    Abstract: An electronic device monitors a quality of a wireless connection between the electronic device and a first access point. Based on the monitoring and a collection of parameters relating to controlling handover between access points, a determination is made regarding whether the electronic device should be handed over to a second access point from the first access point, where the parameters differ for different combinations of the first access point and candidate destination access points for handover of the electronic device from the first access point.
