Research And Implementation Of Remote Configuration Management Terminal Base In TR-069 Protocol

As the development of the Internet,the DSL technology which is the general trend in the broadband access way is used in every gateways of families and corporations.At the same time,as the widely using of the wireless technology,the distribution of the AP is becoming more and more widely.Installing and maintaining every gateway and AP is becoming more and more difficult,and the weakness of low efficiency and high cost is becoming more and more evident.TR-069 protocol which is also called CWMP(CPE WAN Management Protocol) is a protocol of technologic criterion.It is produced by DSL Forum which works for defining and spreading the operation and application based on DSL technology.It defines a mechanism which can auto-configure and manage securely.It realizes auto-configuration and dynamic service provisioning for the remote terminal equipment,software/firmware image management,status and performance monitoring and diagnostics.In this way,all difficulties with manual configuration can be resolved.The main concern of this thesis is to study and realize the theory and the function of the TR-069 protocol.Firstly,this paper introduces the TR-069 protocol of the basic principles of architecture and architecture,and researches the implementation mechanism in the interactive session.Secondly,this thesis designs and implements the functions of the CPE terminal device based on TR-069 protocol in the perspective of application.Designs and implements the internal task processing,as well as receiving and sending the RPC methods,and file transfer processing flow in the main module-CWMP modules,explains the design principle and the implement approach with the data model in TR-069,and implements saving and restoring for the configuration file.In addition,this paper researches the data interactions between the CWMP module and other functional ones,and sets VLAN module as an example to be achieved.All of the design and implementation is based on the configuration management plane.In this way,it shields the difference between the different lower module environments in device,and improves the transplantability of TR-069 protocol between the different devices.Finally,this paper analyses interaction messages in the experiment,and validates the correctness of the TR-069 protocol's functions.
