Method and system for generating 5G end-to-end ticket

Abstract

The invention provides a method and system for generating a 5G end-to-end ticket, and relates to the technical field of communication. The method comprises the steps of transmitting a request message and a response message among a plurality of NF units in an end-to-end message transmission process, wherein the header of the request message and the header of the response message both comprise respective serial numbers and encrypted service process numbers, the service flow number comprises a timestamp and an SUPI. and the SUPI is used as a key for encrypting and decrypting the service process number. The method further comprises the steps that the DPI unit obtains request messages and response messages from the NF units, the encrypted service process number is solved through the SUPI, the request messages and the response messages are associated according to the service process number, the request messages and the response messages are sorted according to respective serial numbers, and therefore the end-to-end ticket is generated. According to the method and the device, the multiple request messages are associated with the response messages, so that the end-to-end ticket is generated, and the user fault can be quickly and automatically positioned.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and system for generating a 5G (the 5th generation mobile communication technology, fifth generation mobile communication technology) end-to-end bill. Background technique [0002] How to quickly analyze user faults for core network maintenance personnel and how to quickly locate the cause of the fault has always been a difficult problem to solve. For single-user faults, packet capture is still the main method, but in the face of large-scale faults, packet capture is obviously too late. Moreover, core network maintenance personnel need to spend a lot of manpower and time when dealing with user faults. For large-scale adjustments to the 5G network architecture, if processing faults still relies on packet capture, it will be difficult for core network maintenance personnel who are already understretched. is unacceptable. [0003] In the era of 4G (t...

Problems solved by technology

When a large-scale failure occurs, the front-end monitoring personnel will feed back a large number of failure numbers, which may or may not be related to the failure. The back-end maintenance personnel cannot tell whether the numbers are related to the failure, and must track them sequentially, which consumes a lot of time and affects the use of users.

The 5G network architecture has been adjusted on a large scale, traditional maintenance methods are facing changes, and a lot of work is automated, but there is currently no good way to automatically handle user faults

If the existing XDR bill generation technology performs multiple interface associations, it needs to filter a large amount of information such as time and IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity), consuming a large amount of computing resources
