Data transmission method, local maintenance terminal, proxy equipment and system

Abstract

The embodiment of the invention relates to a data transmission method, which comprises: through an established file transfer protocol (FTP) data path, a local maintenance terminal simulates user equipment UE to download FTP data from a server on a core network side through network control nodes; and if the FTP data download speed is normal, a data transmission fault is judged to occur at access network. The embodiment of the invention also provides a local maintenance terminal, TCP / IP proxy equipment and a data transmission system. The embodiment of the invention can find a failed network element or a network segment quickly and accurately without any special instrument during data transmission in the established FTP data path, reduce cost and resource consumption and improve throughput between the UE and the server.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data transmission method, a local maintenance terminal, an agent device and a data transmission system. Background technique [0002] In the performance optimization and maintenance of wireless communication systems, the problem of unsatisfactory performance of packet switching (PS, PacketSwitching) data services is often encountered, such as relatively small throughput, which affects the experience of actual users. [0003] In the process of PS service transmission, the connection of its key technical services is end-to-end, and each network element and device carried by it may have data transmission problems or interface problems, such as data packet loss or data transmission during a certain period of data transmission. Congestion, etc., and data packet loss or data congestion in which segment or a certain network element will affect the throughput between users and se...

Problems solved by technology

In this solution, the equipment used (such as K15, Nethawk, etc.) is connected to the standard interface of the core network and the access network, data is collected, and the data is analyzed to locate the network element or network segment where the problem is located. , but its disadvantages are: high cost, requiring special equipment to realize; complex use, need to master the use of the instrument; troublesome operation, need to go to the equipment room for wiring work, which may have a certain impact on network transmission

[0006] During the research and practice of the prior art, the inventors of the present invention found that in the existing implementation scheme, special instruments or equipment are needed, the cost is high and the operation is complicated
