Protocol-Matched PDU Session Selection for Reliable Data Flows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional PDU session establishment in terminal devices may utilize suboptimal route selection parameters, leading to degraded user experience.
Innovation Solution
The method involves determining a PDU session based on a route selection parameter that matches the protocol of the data flow, allowing for improved transmission by establishing or selecting an appropriate PDU session for transport or application layer protocols, and optionally using multiple PDU sessions with switching or aggregation manners to enhance reliability and continuity.

Engineering Contradiction Analysis
1Reliability
If the terminal device uses a conventional route selection parameter for PDU session establishment, then the PDU session can be established, but the user experience is degraded due to suboptimal parameter selection
Solution Approach 1:
The patent changes the route selection parameter from a conventional generic parameter to a protocol-specific parameter. The terminal device obtains a first route selection parameter that is specifically configured for a first protocol (transport layer or application layer protocol), and uses this protocol-matched parameter to determine the PDU session. This parameter change ensures that the route selection is optimized for the specific protocol being used, thereby improving both transmission reliability and user experience.
2Productivity
If the terminal device establishes a PDU session without protocol-matched route selection, then the session establishment process is simple, but the data flow transmission quality is suboptimal
Solution Approach 1:
The patent applies preliminary action by obtaining the protocol-specific route selection parameter before establishing the PDU session. The terminal device first obtains the first route selection parameter that is specifically configured for the first protocol, then uses this parameter to determine the appropriate PDU session for the data flow. This preliminary parameter acquisition ensures that the PDU session is established with optimal route selection from the beginning, improving transmission efficiency without adding significant complexity to the overall process.
Data Source
AI summary
This application provides a communication method and a communication apparatus. In the method, if a protocol corresponding to a first data flow matches a first protocol, a PDU session for transmission of the first data flow may be determined based on a first route selection parameter. The PDU session determined for the first data flow is applicable to the first protocol, so that the determined PDU session can be for better transmission of the first data flow.
