Systems and methods of reducing control plane latency in a 5G IAB network are described. SRs transmitted between nodes indicate that a control plane PDU is to be transmitted. The SRs use periodic resources or OCCs reserved for control plane signaling and are initiated by an RRC message or RACH from the UE. The SRs are initiated if the LCD field in the MAC subheader of the RRC message indicates the CCCH or the DCCH logical channel. If the PDU is available after the original resource, a resource is used that is provided via another grant, which is periodically provided or automatically initiated due to failure to transmit on the original grant. The SR or RRC message can also specify a delayed timeslot for the grant. For contention-based procedures the RACH preamble is randomly selected or selected from among a set of RACH preambles assigned for RRC procedures.

Disclosed are a system, a computer-readable storage medium storing at least one program, and a computer-implemented method of data transmission. A communication module interfaces communicatively with vehicles. A file management module selects first data from a data queue. The first data is addressed to a destination location. The file management module transmits the first data to the first vehicle. The file management module receives an acknowledgement message from a second vehicle interfaced with the communication interface module. The acknowledgement message is indicative of the first vehicle providing the first data to a server at the destination location. The file management module deletes the first data from the data queue.

In one embodiment, a first node in a network receives one or more bitmaps from one or more child nodes of the first node according to a directed acyclic graph (DAG). Each of the one or more child nodes is associated with a corresponding unique bit position in the one or more bitmaps. The first node stores, in a forwarding table, the one or more bitmaps received from the one or more child nodes of the first node. The first node receives a message that includes a destination bitmap that identifies one or more destinations of the message via one or more set bits at bit positions associated with the one or more child nodes. The first node forwards the message towards the identified one or more destinations based on the destination bitmap and the one or more bitmaps stored in the forwarding table of the first node.

In a multiple interface, low power and lossy network comprising a plurality of nodes, a low transmission power and medium transmission power topology are defined for the network and a channel-hopping schedule is defined for the devices operating in each topology. A sender determines that data is capable of being transmitted via a link on the low transmission power topology. The sender determines the transmission parameters for the transmission of the data over the link on the low transmission power topology and determines a low transmission power channel for transmission of the data. The sender transmits the determined channel and the transmission parameters to the receiver. The sender transmits the data via the determined channel in the low transmission power topology.

In one embodiment, network metrics are collected and analyzed in a network having nodes interconnected by communication links. Then, it is predicted whether a network element failure is relatively likely to occur based on the collected and analyzed network metrics. In response to predicting that a network element failure is relatively likely to occur, traffic in the network is rerouted in order to avoid the network element failure before it is likely to occur.

A method and apparatus for device establishing redundant relay nodes in a mesh network.

Disclosed is a communication method, comprising: a source node determines a target path according to the target service parameter of a data packet to be transmitted, the target service parameter comprising at least one of the following information: the service quality requirement of the data packet and a slice corresponding to the data packet; the source node sends the data packet to a target node on the basis of the target path.

System and method for forecasting availability of network services during flight is provided. The system of the disclosed invention utilizes flight plans and coverage data to provide users aboard aircraft with status of satellite Internet services. The system couples the flight plans with the coverage data to provide information regarding how the flight path of the aircraft will affect availability of Internet services during the flight. The method includes retrieving a flight plan to generate a flight path having one or more waypoints, transmitting one or more service coverage data from service providers, coupling the flight path with the service coverage data to determine portions of the flight path in which the network service is unavailable, and delivering to the users information about the service unavailable portions of the flight path.
