Problems solved by technology

This brings about a problem. In the same period of time, when too many messages with the destination address of the same LP Node need to be cached in the Friend Node in a short period of time, there is a possibility that the messages will be overwritten, and the risk of packet loss is high.

Abstract

The invention provides a method and a system for managing friend queues in a Bluetooth Mesh network Friend Node. The method comprises the following steps: message forwarding processing: receiving a first message from a Mesh network by a Friend Node in the Mesh network, and forwarding the first message or at least one message in a friend queue when the friend queue is full. According to the methodand the system, the packet loss risk of the Friend Node can be reduced, and the reliability of the Mesh network is improved.

Description

technical field [0001] The invention relates to the field of Bluetooth Mesh, in particular to a management method and system for a Bluetooth Mesh network friend queue. Background technique [0002] In July 2017, the Bluetooth SIG (Bluetooth Special Interest Group, Bluetooth Technology Alliance) released a many-to-many network based on Bluetooth Low Energy (BLE, Bluetooth Low Energy), that is, the Bluetooth Mesh network. The BLE devices in the Mesh network are called It is a Node, that is, a node, and each node can freely communicate with other nodes through broadcasting. The types of nodes are divided according to their characteristics: LP Node (LowPower Node, low-power node), which is a node with limited power, and uses low power consumption characteristics to save power consumption; Friend Node (friend node), which cooperates with LP Node, Store messages and security updates sent to LPNode, and then transmit the stored information to LP Node when needed by LP Node; Relay ...
