标准范围

IEC 62056-8-12:20 23描述了DLMS的使用？/COSEM用于低功耗广域网(LPWAN)。它指定了COSEM数据模型和DLMS？/COSEM应用层可以使用基于IETF RFC 8724的适配层在各种LPWAN技术上使用，特别是在LoRaWAN上。此配置文件旨在用于IETF RFC 8724中定义的LPWAN，特别是LoRaWAN。低功率广域网(LPWAN)是具有诸如大覆盖区域、低带宽、可能非常小的分组和应用层数据大小以及长电池寿命操作等特征的无线技术。本文档不提供管理LPWAN下层的功能。DLMS的这一部分？/COSEM套件指定低功耗广域网(LPWAN)的通信配置文件。DLMS？/COSEM LPWAN通信配置文件使用基于Internet标准用户数据报协议(UDP)和Internet协议(IPv6)的无连接传输层。适配层基于IETF RFC 8724，其提供报头压缩/解压缩机制和可选的分段/重组机制。SCHC压缩基于具有小上下文标识符的静态上下文来表示完整的IPv6/UDP/COSEM包装报头。如果需要，SCHC分段用于支持LPWAN技术上的IPv6 MTU。本文件的结构遵循IEC 62056-5-3:20 23附录A、IEC 62056-1-0和IEC TS 62056-1-1:20 16中定义的规则。示例另见附件A

IEC 62056-8-12:2023 describes the use of DLMS？/COSEM for Low-Power Wide Area Networks (LPWANs). It specifies how the COSEM data model and the DLMS？/COSEM application layer can be used over various LPWAN technologies using an adaptation layer based on IETF RFC 8724, and in particular over LoRaWAN.
This profile is intended to be used with LPWANs as defined in IETF RFC 8724, in particular LoRaWAN. Low-Power Wide Area Networks (LPWANs) are wireless technologies with characteristics such as large coverage areas, low bandwidth, possibly very small packet and application-layer data sizes, and long battery life operation. This document does not provide functionality to manage the lower layers of the LPWANs.
This part of the DLMS？/COSEM suite specifies the communication profile for Low-Power Wide Area Networks (LPWANs).
The DLMS？/COSEM LPWAN communication profiles use connection-less transport layer based on the Internet Standard User Datagram Protocol (UDP) and Internet Protocol (IPv6).
The adaptation layer is based on IETF RFC 8724 which provides both a header compression/decompression mechanism and an optional fragmentation/reassembly mechanism. SCHC compression is based on static context with small context identifier to represent full IPv6/UDP/COSEM wrapper headers. If required, SCHC fragmentation is used to support IPv6 MTU over the LPWAN technologies.
This document follows the rules defined in IEC 62056-5-3:2023, Annex A, and in IEC 62056-1-0, and IEC TS 62056-1-1:2016 for its structure. See also Annex A for examples
