Brief introduction of preparation for 3g-oma protocol and public document download

Along with the rapid development of 3G technology in China, the data business is bound to become an important means of communication between consumers and enterprise users, and these trends pose significant management challenges to mobile operators (while extending mobile data services to different mobile devices of different network types are also challenging).
Mobile Device Management (Device Management) is a response to this management challenge and ensures that all mobile devices connected to the carrier network can provide high-quality mobile data services. Mobile device Management provides support for mobile devices such as 2G, 3G, WiMAX, and so on. OMA based on the OTA (over-the-air) Device Management Framework provides a solution for mobile device management, the OMA DM protocol is clearly independent of the hosting network, so the protocol can be used for a variety of networks, including mobile cellular networks, Bluetooth, Ethernet, Wi-Fi, WiMAX, etc. It spans 2G, 3G, and WiMAX technology.

Why the OMA protocol is needed
With the rapid development of global mobile communication, in order to improve the quality of mobile communication service, meet the needs of people, and solve the problem of data synchronization between different networks, and then realize interconnection, the urgent task is to establish a universal and safe and reliable Unified standards and specifications for easy to operate End-to-end mobile communications. The Global Standardization organization OMA (Open Mobile Alliance) Open Mobility Alliance was founded on June 12, 2002. It is a demand-oriented approach.

TR069 Protocol and OMA Protocol

With VoIP, IPTV and more and more IP terminal equipment popularization (especially in the family), a large number of equipment configuration and maintenance becomes more and more difficult, greatly improve the cost of network product operators, the traditional SNMP based network management system in the face of a large number of terminal equipment is powerless, Limits the development speed and scale of the broadband access market. TR069 defines a brand new network management architecture, including "Administrative Model", "Interaction Interface", "Management parameters", to a large extent, reduce the cost of the transport of networked products, so the focus of the TR069 protocol is practical application, that is, the application layer of the OSI protocol model.
Unlike the TR069 protocol, OMA is designed to support data synchronization between different networks of different devices, so OMA's data transmission is not only built on the Internet session layer using HTTP transmission, OMA also supports wireless network WAP using WSP and Bluetooth network using OBEs for data transmission, and so on. Different networks are only different transmission tools, but because of the common use of the standard SYNCML data packet, the data synchronization between different networks, so that the intermediary interoperability tools to achieve different networks and devices between the data interaction. OMA was designed to focus on the presentation layer of the OSI protocol model in terms of data synchronization, desalination of devices, operating systems, and the impact of the network on data interaction.
