Embodiments of the present invention disclose a network channel switching method and apparatus, a device, and a storage medium. The method comprises: acquiring network channel switching information sent by an upper-level parent-node device having a connection relationship, and sending the network channel switching information to a lower-level child-node device having a connection relationship; and switching, according to the received network channel switching information, from a current channel to a target channel. The technical solution in the embodiments of the present invention can greatly improve the success rate of each node device receiving network channel switching information in a mesh network, such that channel switching across the entire mesh network can be achieved while maintaining connections between the node devices in the network, thereby improving the efficiency of channel switching in the mesh network.

Diversity receiver front end system with flexible antenna routing. A receiving system can include a plurality of amplifiers. Each one of the plurality of amplifiers can be disposed along a corresponding one of a plurality of paths between an input of the receiving system and an output of the receiving system. Each one of the plurality of paths can correspond to a different frequency band. The receiving system can include an input multiplexer configured to receive, at one or more of a plurality of input multiplexer inputs, one or more RF signals. Each one of the one or more RF signals can include one or more frequency bands. The input multiplexer can be configured to output each of the one or more RF signals to one or more of a plurality of input multiplexer outputs. The receiving system can include a controller configured to receive an antenna configuration signal and, based on the antenna configuration signal, control the input multiplexer to route each of the one or more RF signals to propagate along one or more of the plurality of paths corresponding to the one of more frequency bands of the RF signal.

Systems, methods, and computer-readable media for assessing reliability and trustworthiness of devices operating within a network. A recipient node in a network environment can receive a neighbor discovery (ND) message from an originating node in the network environment that are both implementing a neighbor discovery protocol. Trustworthiness of the originating node can be verified by identifying a level of trust of the originating node based on attestation information for the originating node included in the ND message received at the recipient node. Connectivity with the recipient node through the network environment can be managed based on the level of trust of the originating node identified from the attestation information included in the ND message.

A routing rule configuration method and a communications apparatus are provided. In the method, after receiving a PDU session establishment request from a first terminal, a session management function network element generates, based on first information including information used to indicate to forward a data packet through an N6 interface, a routing rule used to indicate to send the data packet of a 5G LAN group to which the first terminal belongs to the N6 interface or discard the data packet. The session management function network element can determine a routing rule for an N6-based forwarding manner based on the first information.

A system described herein may provide a technique for the discovery and connection of Mesh Distributed Units (“MDUs”), which may establish a mesh topology and perform wireless backhaul of data between a core network and a User Equipment (“UE”). Multiple MDUs in an MDU network may be connected to establish an MDU route. One or more connected MDUs may broadcast an indication that the MDU is available to connect, one or more performance metrics, or an MDU performance score based on performance metrics. This broadcast may iteratively repeat in order to refine the mesh network topology in an ongoing process.

Disclosed is a method of mapping optimal communication routes through a mesh network.

A user equipment (UE) may determine that a synchronous transmission by the UE includes traffic having a priority higher than a priority of nominal traffic. In response to the determination, the UE may, alter a use of at least some of an initial portion of a discovery frame from energy detection to signal transmission. The signal transmission may be a pilot signal transmission or a non-information-carrying signal transmission. The traffic having the priority higher than the nominal traffic may include mission-critical traffic. A reliability requirement of mission-critical traffic may be higher than a reliability requirement of nominal traffic. A latency requirement of mission-critical traffic may be lower than a latency requirement of nominal traffic. The signal transmission may be at a power level that is sufficient to result in energy detection at another UE. Various additional and alternative aspects are described herein.

A network device with wireless access point capabilities selectively captures PDUs detected on an instrumented interface(s) to capture those of one or more types/subtypes “of interest.” PDU types/subtypes that network device interface(s) has been instrumented to treat as “of interest” include those transmitted during a device's initial network activity during startup or attempted establishment of a wireless network connection. The interface(s) instrumented for targeted PDU capture can include wireless and/or wired (e.g., Ethernet) interfaces that are received on raw sockets so that each header type of a captured PDU is written to the PDU capture file. Prior to upload of a PDU capture file to a system from which it can be retrieved for analysis, the network device adds network metadata to the file based on context of the environment in which the network device operates. The network metadata can include IP address and/or network topology information determined at runtime.

The present invention relates to a content-centric network on-demand distance vector route method, comprising: a request source node of a required request route broadcasts a route request packet CCN_RREQ to other nodes in a network, and starts a route discovery process; after a target node receives the route request packet CCN_RREQ, replying with a route reply packet CCN_RREP; after the request source node receives the route reply packet CCN_RREP returned by the target node, establishing a path between the request source node and the target node according to the content of the route reply packet CCN_RREP.

A method and apparatus for prioritizing one of a multimedia broadcast multicast service (MBMS) reception or a device-to-device (D2D) reception in a wireless communication system is provided. A user equipment (UE) prioritizes one of the MBMS reception or the D2D reception if the UE cannot support both MBMS reception and the D2D reception simultaneously, and indicates a result of the prioritization to the network. The result of the prioritization indicates either that the MBMS reception is prioritized over the D2D reception or the D2D reception is prioritized over the MBMS reception.
