Terminal Server-Address Requests Within PDU Session Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack flexibility in obtaining server addresses, limiting the ability of terminals to dynamically adjust services such as AI model downloads and computing power utilization.
Innovation Solution
Terminals send first indication information in messages for establishing or modifying PDU sessions or registration to request server addresses, using methods like PDU session parameters, SM core network capabilities, or UE policy containers, enabling dynamic server address acquisition without additional signaling overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal obtains server address through pre-configured information, then the terminal can obtain a fixed server address, but flexibility of obtaining server address is poor
Solution Approach 1:
The patent merges the server address request function with existing PDU session establishment, modification, or registration messages. The terminal includes first indication information in these existing messages to request server address, and the network side device responds with server address in the corresponding acknowledgment messages. This combining approach enables flexible server address acquisition without introducing separate dedicated signaling procedures, thus avoiding additional signaling overhead while improving adaptability.
2Adaptability or versatility
If additional signaling is used to request server address, then flexibility of obtaining server address is improved, but signaling overhead increases
Solution Approach 1:
The patent makes existing PDU session messages serve multiple functions: they simultaneously handle PDU session management tasks and convey server address request information. The first indication information embedded in these universal messages enables the terminal to request server address during normal PDU session operations, allowing one message type to fulfill multiple communication needs without requiring dedicated signaling resources.
