Research On Terminal Equipment Management Based On TR069 Protocol

With the rapid development of Internet technology and broadband network technology and the emergence of all sorts of rich Internet application and popularization,Network terminal devices are becoming more and more complex and play an important role,thus an effective way of management has become a top priority,because you can truly achieve zero configuration installation and management of business.Since its emergence,TR069(CPE Wan Management Protocol)protocol has solved many problems and greatly solved the problems and difficulties facedd by operators in terminal equipment management,and provided a strong guarantee for operators to reduce the installation and maintenance management costs of user terminal equipment,improve the efficiency of equipment management and maintenance,and improve the quality of business services.The main contents of this paper are as follows:(1)Study the current situation at home and abroad,through analysis and comparison to find the necessity of the subject research,understands the development history and trend of terminal management technology,makes clear the research significance of the subject,deeply understands the TR069 protocol,and carries out the overall system design in certain technical specifications and some specific requirements;(2)Based on the basic theory,the relevant knowledge of TR069 protocol is studied.The layered research is carried out based on the TR069 protocol stack,and the system design is carried out through the layered mode;(3)With the constraints of TR098 and TR181,the use of TR069 can be increased through the research and implementation of constantly updated and improved nodes.(4)Using XMPP(Extensible Messaging and Presence Protocol)technology to assist communication,TR069 private network traversal is realized.It is proved that compared with THE STUN(Simple Traversal of UDP Through NAT)technology which can also realize the private net work traversal,the private network traversal based on XMPP technology has stronger stability,higher success rate of active connection,and higher practical value;(5)In order to meet operators requirements of “real-time monitoring equipment” and “efficient management equipment” and reduce maintenance costs,c language is used for development,UBUS is used for communication,and OPENSSL is usde to support HTTPS.TR069 adaptation library layer and data model transformation layer are designed to shield the differences of devices,so as to improve the portability of code.At present,it is running normally in the international gateway.Finally,the article analyzes the interactive messages through different tests to verify the intended functionality of TR069.The test shows that the designed TR069 module is reasonable,all basic functions can run normally,CPE(Customer Premise Equipment)and ACS(Auto Configuration Server)can interact normally,and ACS based on XMPP technology can access CPE through the private network,achieving the expected goal.
