AI Technical Summary

Technical Problem

In local area network scenarios, existing technologies cannot effectively process uplink information, causing user plane functional entities to be unable to correctly perceive or execute the source and destination addresses in packet inspection rules (PDR).

Method used

The session management function entity generates and sends uplink PDR information carrying indication information, enabling the user plane function entity to exchange source and destination addresses to ensure address consistency and thus correctly perceive the PDR.

Benefits of technology

By exchanging source and destination addresses in a local area network scenario, the user plane functional entities are able to correctly process uplink flow information, thus achieving reasonable detection and classification of data packets.

Abstract

This application provides a communication method and apparatus, belonging to the field of communication technology, for processing uplink flow information appropriately in a local area network (LAN) scenario. In this method, a session management function entity sends an instruction to a user plane function entity to instruct the exchange of source and destination addresses in the first PDR information. This allows the user plane function entity to exchange the source and destination addresses in the flow description information of the first PDR information based on the instruction. This enables appropriate processing of the uplink flow information, ensuring that the source address perceived by the user plane function entity in the flow description information matches the address of the source interface included in the uplink PDR information, thus allowing the user plane function entity to correctly perceive the first PDR information.
