  • Patent number: 11368393
    Abstract: Disclosed embodiments relate to a Hierarchical Do-Dag based RPL (H-DOC) network configuration where the network address of each node corresponds to its location within the hierarchical network. Network addresses are initialized hierarchically. Candidate patent nodes signal availability. Candidate child nodes respond to a selected candidate parent node with a temporary address. The selected candidate parent node acknowledges selection and communicates a hierarchical address for the child node in a transmission to the temporary address. The child node changes its address to the hierarchical address from the parent node. When a node switches parent nodes, it signals the old parent node to deallocate it as a child node, and then signals a selected candidate parent node with a temporary address.

  • Patent number: 11329875
    Abstract: A method of switching from a first gateway within a plurality of first gateways to a second gateway in a network includes precaching configuration information on the second gateway, that is within the first gateways, prior to switch-over to the second gateway. The first gateway from which the second gateway is being switched is identified. The second gateway is configured in accordance with the configuration of the first gateway based on the precached configuration information prior to the switch-over to the second gateway. Data traffic from data applications using the network is replicated and sent to the first gateway and the second gateway. Bandwidths allocated to terminals in the network are frozen in association with the switch-over to the second gateway. The bandwidths allocated to the terminals in the network are unfrozen based at least in part on an indication of completion of the switch-over to the second gateway.

  • Patent number: 11330653
    Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support multi-connectivity for a user equipment (UE) with multiple distributed units (DUs) under one central unit (CU), the DUs and the CU belonging to a base station. The UE may establish radio resource control (RRC) connections with multiple cell groups corresponding to multiple DUs under the CU. The UE may transmit measurement reports that provide measurement information for cells in proximity to the UE. The UE may maintain a set of active cell groups and a set of inactive cell groups. In some cases, one or more cell groups may be identified as controlling cell groups used to transmit control information. In some examples, the UE may replicate an uplink packets and transmit the uplink packet and replicates on multiple cell groups. In some cases, the UE may aggregate an uplink transmission among multiple cell groups.

A working state on the first carrier and a working state on the second carrier can be determined by the terminal device as a first working state, and a second working state, respectively. The first working state indicates the terminal device is capable of sending a first signal including at least one of an uplink data signal and an uplink control signal, and the second working state indicates the terminal device is incapable of sending the first signal. First indication information can be received by the terminal device from a network device. Based on the first indication information, the terminal device can determine that the working state on the first carrier is the second working state, and the working state on the second carrier is the first working state.
