Embodiment Construction

[0043] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the following The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] see figure 1 shown. The broadband carrier communication network protocol stack is based on the standard Open System Interconnection (OSI) seven-layer model, which defines three layers: the physical layer, the data link layer, and the application layer.

[0045] The data link layer is divided into the network management sublayer a...

Abstract

The invention discloses a method for networking a broadband power line communication network, which includes: when any STA device of any network is performing a network access operation, it listens for a period of continuous time, and judges whether any STA device of any network has received any information within the continuous time. Beacon frame; if the beacon frame is received, it is judged whether the beacon frame of only one network is received; if the beacon frame of at least two networks is received, the STA device communicates with the The CCO device of the network closest to the MAC address of the STA device sends a network access request message. This networking method enables STA devices to reasonably select beacon frames received from the network when they join the network. By selecting the MAC address distance, the number of packets sent by STA devices to non-corresponding network CCO devices is reduced, avoiding It reduces the waste of useless packets, reduces the burden of the channel during the network access process, and improves the quality of channel transmission and the utilization of channel resources.

Description

technical field [0001] The invention belongs to the technical field of broadband power line communication, and in particular relates to a method for networking a broadband power line communication network. Background technique [0002] PLC (Power Line Communication) refers to a communication method using power lines as the transmission medium. It is mainly used in remote automatic meter reading, automatic control of distribution network, internal interconnection of homes, intelligent communities and the last mile network of multimedia communication. Access, etc., has the characteristics of fast construction, low investment, and no need for indoor wiring. In recent years, the development of BPL (Broadband over Power Line, broadband power line communication) related technology has improved the data transmission rate of power line communication, especially the development of orthogonal frequency division multiplexing technology has enabled high-speed PLC to be realized. With t...
