摘要
OMA-DM是OMA组织定义的一套用于移动与无线网络的终端管理协议。研究了OMA-DM协议在嵌入式终端设备中的实现方案。首先,详细分析了DM协议特点及会话流程,再根据嵌入式终端设备特性,采取模块化架构设计,阐述了DM协议与MMI、EFS、协议栈之间的接口关系,DM tree及会话流程等关键技术实现过程。该方案充分考虑了嵌入式系统平台资源,在降低开发难度的同时提高了系统可移植性。
OMA-DM is a device management protocol designed by Open Mobile Alliance for mobile and wireless network, this article has given a implementation of OMA-DM on embedded device. It deeply analyzes the characteristics and session flow of DM protocol uses method of modularized architecture design according to the characteristics of embedded device, describes the relationship between DM protocol and MMI, EFS, protocol stack, and gives implementation of key techniques like DM tree and session flow. This solution fully considers the resources of embedded system, reducing the difficulty of development while increasing system portability.
