  • Patent number: 9867157
    Abstract: A method for detachment of a mobile set within the equivalent route area moving between the communication systems comprising steps of: during the detachment process is implemented between a mobile set and a service node in one communication system, the service node generates one or more messages and transmits it to the service nodes in one or more communication system within the ERA. If the message is transmitted to the service node within the ERA of only one communication system, this service node transmits this message or the message generated according to this message to the service nodes within the ERA of the other communication system. With the method proposed in present invention, when a mobile is detached from two or more communication systems which share the same ERA, the service nodes in all communication systems within the ERA can still correctly manage the relevant information on this mobile set.

  • Patent number: 9847912
    Abstract: Mesh network resiliency technology, in which a first routing configuration for nodes of a mesh network is determined, the first routing configuration being appropriate when a first power source of the mesh network is available. Routing data that indicates routing responsibilities within the first routing configuration is provided to first nodes of the mesh network. An interruption of the first power source for the mesh network is detected by nodes of the mesh network. In response to detecting the interruption, a second routing configuration for nodes of the mesh network is determined, the second routing configuration being appropriate when the first power source of the mesh network is unavailable. Routing data that indicates routing responsibilities within the second configuration is provided to second nodes of the mesh network, each of the second nodes including a second power source that is different than the first power source.

  • Patent number: 9826543
    Abstract: A method and apparatus for determining when to switch between buffer estimation states for a fixed frame rate services session at a terminal. In the event that the state is passive, a network node determines a first time between two received Radio Link Control Service Data Units (RLC SDU). If the first time is lower than a first time threshold, then the state is changed to proactive. When the state is proactive, the network node determines that two consecutive padding transport blocks have been received and further determines that a second time between two padding transport blocks is greater than a second time threshold. If so then the state is changed to passive.
