Design And Implementation Of TD-Femto Network Management Software Based On TR-069 Protocol

At present,while the wide developement and commercial usage of 3G network bring convenience to people's life,its defects like poor signal coverage of indoor buildings are found TD-Femto emerged.TD-Femto effectively improves the quality of indoor signal coverage in a 3G network environment,but it is difficult to manage and maintain in the process of large-scale deployment.Traditional SNMP protocols in terms of TD-Femto management and maintenance,so the TR-069 protocol was developed on the DSL Forum.Based on the study of TR-069 protocol,this paper implements the TR-069 protocol client function on TD-Femto technology.Firstly,the background of TD-Femto is expounded,and its grid structure and hardware platform are studied.At the same time,the management model,main function,session security mechanism and protocol hierarchy of TR-069 protocol are studied,and more in-depth study of the encapsulation process and interactive process of RPC packets lays a solid foundation for the realization of remote management of terminal equipment.Based on TR-069 and relevant protocols,the requirements of TD-Femto network management system software are analyzed according to the technical characteristics of TD-Femto and the actual requirements of the project.Firstly,on the basis of TD-Femto technical characteristics,TD-Femto gateway discovery,registration process and configuration process are studied in depth,and the automatic configuration function is completed.Secondly,TD-Femto devices need to complete configuration management,performance management and other basic functions.Meanwhile,TD-Femto also needs to support RPC methods,data models and security mechanisms.Secondly,based on the requirement analysis,under the actual engineering background,the remote network management software of the TR-069 client is designed and implemented on the TD-Femto device.Through the design of network management function module architecture and state machine,the overall design of thesystem software is achieved: A state machine is set in the main control module to achieve efficient management of event tasks.The retransmission mechanism and congestion control mechanism adopted and make the process of data processing more efficient.Multi-thread design mode is used,the design of the main thread and other three threads are designed to effectively improve the system's response speed.Finally,the function and principle of HTTP packet / resolution and other modules are analyzed,the corresponding function is realized,and the concrete flow chart of the design process is given.Based on the study of TR-196 protocols,the tree structure storage parameter model is designed to facilitate the search,addition and deletion of its parameters.Finally,the communication process between ACS and CPE is captured by Wireshark capturing software,and the result of packet capturing is analyzed.The online experiment and the actual test show that the TD-Femto network management software that is completed in t the paper is stable and robust.Meanwhile,it has been successfully applied in houses,remote areas and other places.
