There is provided an apparatus, said apparatus comprising, at a multicast/broadcast session management function of a core network, means for receiving information related to a shared centralised unit user plane, CU UP for a multicast/broadcast session, from a radio access network, RAN, node or an access management function of the core network, means for determining, based on the information, whether to configure a user plane function of the core network to deliver data or to terminate delivery of data for the multicast/broadcast session towards the shared CU UP and means for, if so, configuring the user plane function to deliver data or to terminate delivery of data for the multicast/broadcast session towards the shared CU UP

The present invention provides a packet processing method and system, and a network device. The method includes: receiving, by a first network device, a packet, where the packet includes match object information and match condition information; determining, by the first network device, a to-be-matched second network device according to the match object information, where the second network device includes one or more network devices; matching, by the first network device, device information of the second network device with the match condition information; and performing, by the first network device, forwarding processing or discarding processing on the packet according to a match result of matching the device information of the second network device with the match condition information. By using the method provided in the present invention, excessive occupation of network bandwidth can be reduced, and network resources can be saved.

A network includes a mobile network node (MNN) that includes a mobile node communications manager (MNCM) to facilitate wireless communications to a plurality of stationary network nodes (SNNs) in a wireless network via a wireless network protocol. The MNCM utilizes a multicast address received over the wireless network. The multicast address is assigned to a predetermined network time slot to communicate uplink data from the MNN to the SNNs. The MNN receives downlink data via a separate predetermined network address and time slot assigned to a given SNN.

A MANET protocol, comprising: receiving a data packet (DP) from a current sender (CS) by a recipient, defining: an identity of the CS, a prior sender (PS) from which CS received DP, and a target recipient (ID), a count (HC) of hops previously traversed by DP, and a sequence identifier (SI); updating a forwarding table (FT) to mark CS as being reachable in one hop, and PS as being reachable in two hops via CS as next hop; determining if ID is the recipient; determining whether to rebroadcast by recipient, if and only if the SI is not present in a list of prior SIs; and selectively rebroadcasting DP by recipient in dependence on said determining, modified by: replacement of CS with an identity of the recipient, PS with CS, and ID with a next hop from the FT if present, and incrementing HC.

Apparatuses, methods, and systems for coordinated access to a wireless link through data profiles are disclosed. One method includes receiving through the wireless link, by each hub associated with a base station, one or more data profiles from a network management element, receiving, by each hub, data from data sources associated with the hub, controlling, by each hub, a timing of communication of the data for each of the data sources from the hub to the base station through the wireless link based on the one or more data profiles, allocating preamble codes to each of the data sources, wherein different preamble codes are allocated to different data sources of different hubs that report within a margin of time of each other, and including the allocated preamble codes with the data of each of the data sources.

Local weather information such as a nationwide emergency network for first responders can enable first responders to communicate nationally with a single network, linking to suppliers, utilities, and weather information. The system disclosed herein can provide data to first responders and data from first responders can provide insights into local conditions that can be utilized by edge data centers. Adding first responder data can improve the processing speed of moving of edge-based applications out of threatened data centers. Because this movement can also have an impact on low latency applications, identifying the closest edge sites without an impact can keep the applications operating.

A method of enabling a publisher mesh node to update a number of hops that is to be used for communication between said publisher mesh node and a subscriber mesh node in a wireless mesh network, wherein said method comprises the steps of periodically receiving, by said subscriber mesh node, broadcasted messages from said publisher mesh node, wherein said broadcasted messages comprise a number of hops that said broadcasted messages may traverse in said mesh network, determining, by said subscriber mesh node, that one or more periodically broadcasted messages have not been received, transmitting, by said subscriber mesh node in reply to said determination that one or more periodically broadcasted messages have not been received, a probe message to said publisher mesh node, wherein said probe message comprises a number of hops corresponding to a periodically broadcasted message that was received by said subscriber mesh node.

A method of hop count matrix recovery based on a decision tree classifier, includes: S1: performing a flooding process to acquire a hop count matrix {tilde over (H)} with missing entries; S2: constructing a training sample set according to relationships between a part of observed hop counts in the hop count matrix {tilde over (H)}, and modeling the observed hop counts in the hop count matrix as labels of the training sample set, wherein a maximum hop count represents a number of classes; S3: training a decision tree classifier according to the training sample set obtained in step S2; and S4: constructing a feature for an unobserved hop count, to obtain an unknown sample; and inputting the unknown sample to the trained decision tree classifier, to obtain a class of the unknown sample which represents a missing hop count at a corresponding position in the matrix, to recover a complete hop count matrix H.

A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a next node belonging to the limited portion of the network and located along an available network path between the node and the target node is determined, and the packet is forwarded to the next node.

A packet sending method includes: receiving, by a first node, a first broadcast data packet sent by a second node; and if a sequence number of the first broadcast data packet equals 1 plus a sequence number of a latest data packet saved by the first node, and the first node does not receive, within a first preset time period, a first acknowledgement indication for the first broadcast data packet of the second node, sending, by the first node, a first broadcast acknowledgement packet when the first preset time period elapses, where the first broadcast acknowledgement packet includes the first acknowledgement indication, and the first acknowledgement indication includes the sequence number of the first broadcast data packet and an address of the second node. This method could resolve acknowledgement packet implosion while ensuring broadcast packet reliability of a wireless mesh network.
