Node-Level DNS Rule Distribution for 5G Session Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent request and distribution of DNS message processing rules in 5G networks lead to complex processing procedures, resulting in low efficiency during the creation of PDU sessions and DNS message handling.
Innovation Solution
A data processing method and apparatus that generate a node-level message processing rule set and distribute it to an edge application server discovery network element, allowing it to process DNS messages without relying on the creation of each PDU session, thereby reducing the need for frequent rule updates and improving processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DNS message processing rules are distributed for each PDU session creation, then the processing can be customized per session, but the processing procedure becomes complex and efficiency decreases
Solution Approach 1:
The patent segments the DNS message processing rules into two levels: node-level rules that apply globally to all PDU sessions, and session-level rules that are specific to individual sessions. This segmentation allows the system to maintain customized processing where needed while avoiding the complexity of distributing full rule sets for every session creation.
Solution Approach 2:
The patent introduces a universal node-level message processing rule set that can be applied across multiple PDU sessions. This universal rule set handles common DNS processing requirements, reducing the need for repeated distribution of identical rules and simplifying the overall processing procedure while maintaining adaptability through session-specific overrides when necessary.
2Reliability
If DNS message processing rules are distributed frequently for each PDU session or DNS message, then the processing can be up-to-date, but the processing efficiency of DNS messages becomes low
Solution Approach 1:
The patent applies preliminary action by establishing node-level message processing rules in advance, before individual PDU sessions are created. These pre-configured rules are stored and readily available for application, eliminating the need for frequent rule distribution and interaction between SMF and EASDF during session creation or DNS message processing.
Solution Approach 2:
The EASDF is configured with node-level message processing rules that enable it to independently process DNS messages without requiring frequent interactions with the SMF for rule updates. This self-service capability improves processing efficiency by allowing the EASDF to handle DNS messages autonomously based on pre-established rules.
Data Source
AI summary
This application discloses a data processing method performed by a computer device acting as a session management network element. The method includes: generating a node-level message processing rule set, where the message processing rule set includes one or more message processing rules; and distributing, when the session management network element establishes a connection with an edge application server discovery network element, the message processing rule set to the edge application server discovery network element, so that the edge application server discovery network element processes a received domain name system message according to the message processing rule set in a subsequent protocol data unit session process. According to this application, the processing efficiency of the domain name system message may be improved.
