The disclosure relates to method and system for geographic routing mesh network. The method may include determining, by a first node, a first list of nodes proximal to the first node in a mesh network. The method further includes sending, by the first node to each node on the first list of nodes, the first list of nodes proximal to the first node. The method(s) further includes receiving, by the first node in response to sending the first list of nodes, one or more second list of nodes from one or more nodes of the first list of nodes, each of the one or more second list of nodes being proximal to one of the one or more nodes of the first list of nodes and updating, by the first node in response to receiving one or more second list of nodes proximal to the one more nodes of the first list of nodes, one or more nodes of the first list of nodes.

Methods and/or systems for managing continuity of data flow in 5G networks. A UE may receive a message from a 5G network in response to a PDU session establishment request. The message indicates a failure to establish a PDU session with a first DNN and a first network slice. A PDU session may be established with at least one of a second DNN and a second network slice, if the PDU session is matching with a route selection descriptor applicable to data traffic to be routed through the PDU session. A non-CIoT device may receive a message from a 5G network in response to a service request. The message may indicate failure of a service request procedure, pertaining to a PDU session, such as due to insufficient user-plane resources. The PDU session may be closed and reestablished. If there is lower layer failure in 5G, a connection may be established with a 4G network for data transfer.

One or more processing circuitries of the apparatus are to: receive a plurality of service data flows (SDFs) associated with respective applications to be executed, the SDFs including data packets; determine first Quality of Service (QoS) flows corresponding to a plurality of first QoS requirements for the SDFs, wherein SDFs associated with a same application correspond to a same QoS requirement of the plurality of first QoS requirements; change the first QoS flows to second QoS flows different from the first QoS flows, the second QoS flows corresponding to a plurality of second QoS requirements for respective ones of the SDFs, the second QoS flows based on the respective applications and further based on respective ones of the data packets; and send for transmission from the output the plurality of SDFs based on the second QoS flows.

A method performed in an Internet of Vehicles data transmission system is provided in the present disclosure, where the Internet of Vehicles data transmission system includes a plurality of clusters and at least one road-side unit connected to the Internet, each cluster includes at least one on-board unit, and the at least one on-board unit includes a cluster head on-board unit, and the method includes: transmitting data in the on-board unit to one of the at least one road-side unit, via the cluster head on-board unit of the cluster where the on-board unit belongs. An on-board unit and an Internet of Vehicles data transmission system are further provided.

A relay device includes: a storage unit storing a correspondence table that correlates header information with a relay resource, the relay resource implementing a communication request class defined based on the header information; a data acquisition unit acquiring the data transmitted from the transmission source device as acquired data; a relay resource determination unit determining a relay resource for the acquired data based on header information included in the acquired data and the correspondence table; and a data transmission unit transmitting the acquired data to the destination device using the relay resource determined by the relay resource determination unit.

A method for restricting multi-connectivity functionality of a user equipment (UE) includes: storing a mapping table on a memory of the UE, wherein the mapping table provides assignment information about a respective single access mode assigned to a service requestable by the UE, wherein the respective single access mode is one of multiple access modes; receiving service information about a requested service via a network interface of the UE; comparing, by a process of the UE, the service information to entries of the mapping table, and selecting a single access mode assigned to the requested service; wherein the multi-connectivity functionality of the UE is restricted by: a bypass entity redirecting data traffic associated with the requested service directly to the selected single access mode; or a multipath scheduler scheduling data traffic associated with the requested service to a communication link that corresponds to the selected single access mode.

Packets are routed in a data network comprising a wireless mesh network and a controller providing IPv6 management traffic to nodes of the wireless network. A monitor function and a route table manager are used to generate a route table relating IPv6 addresses to each of the nodes via a respective one of a plurality of POP nodes, by accessing a pre-configured topology file, determining the reachability of each of the plurality of POP nodes from the controller by periodically sending test messages from the monitor function to each POP and detecting acknowledgement of the test messages. If a POP node is not reachable, the route table is updated to relate the IPv6 subnet of the POP that is not reachable to the address of a POP node that is reachable. A Layer 2 network is used to direct the IPv6 management traffic according to the amended route table.

The present technology enables inter-network routing by dynamically optimizing data paths for traffic destined for wired clients attached to a wireless access point in a wireless mesh network with a plurality of wireless access points. The present technology can also influence steering of wireless device connections within the wireless mesh network when high amounts of data traffic are exchanged between nearby mesh wireless access points.

A communications system may include mobile communications nodes operating according to a current topology and reconfigurable to a new topology. Each mobile communications node may include a wireless transceiver, and a controller configured to transmit spectral performance data to adjacent nodes and receive spectral performance data from the adjacent nodes. The controller may identify potential topologies for the adjacent nodes based on the spectral performance data, select a subset of potential topologies from among the potential topologies, generate a respective performance score for each potential topology of the subset of potential topologies, and switch to a new topology from among the subset of potential topologies based upon the performance scores.

A method for user equipment route selection policy (URSP) rule-based application data routing, user equipment (UE), and a storage medium are provided. The method includes: obtaining, by the UE, a list of URSP rules and a route selection descriptor (RSD) indication in the list of URSP rules, and establishing protocol data unit (PDU) sessions according to the RSD indication; obtaining, by the UE, traffic descriptor (TD) parameters in the URSP rules, and establishing a mapping between the TD parameters and the PDU sessions; and obtaining, by the UE, application data and a parameter corresponding to the application data, and determining a routing path of the application data according to the parameter and the mapping.
