UE Parameter Update Capability Check via Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in performing user equipment (UE) parameters update (UPU) capability checks, particularly when UE capabilities are not available to provide specific data set types, leading to inefficiencies and increased computational complexity due to the need for multiple rounds of UPU procedures.
Innovation Solution
The method involves determining to invoke a UE UPU capability check by transmitting messages with UPU priority information, capability check required information, and required data type support information between network functions, including the authentication server function (AUSF) and the UE, to verify and update parameters efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple rounds of UPU procedures are performed to check UE capabilities, then parameter update reliability is improved, but procedure complexity and computational overhead increase
Solution Approach 1:
The patent applies preliminary action by performing the UE capability check for data set types before initiating the UPU procedure. The network function determines whether the UE supports required data set types (such as UPF relocation, PDU session establishment) in advance, so that the UPU procedure can be executed in a single round without requiring multiple capability negotiation rounds, thereby reducing procedure complexity while maintaining reliability
Solution Approach 2:
The patent extracts the capability check step from the UPU procedure and performs it independently beforehand. By separating the capability verification (checking if UE supports specific data set types) from the actual parameter update procedure, the system avoids iterative complexity while ensuring the UPU can proceed reliably in one execution
2Measurement precision
If multiple rounds of UPU procedures are performed, then capability verification accuracy is improved, but signaling overhead and processing time increase
Solution Approach 1:
The capability verification is performed as a preliminary action before the UPU procedure. The network function checks whether the UE supports the required data set types in advance, ensuring accurate capability verification without requiring multiple UPU procedure rounds, thereby reducing the overall processing time and signaling overhead
3Productivity
If UPU capability check is integrated into the UPU procedure, then computational efficiency is improved, but procedure complexity increases
Solution Approach 1:
The capability check is performed as a preliminary action that determines whether to proceed with the UPU procedure. This integration allows the system to make an early decision based on UE capability support for required data set types, improving computational efficiency by avoiding unnecessary UPU procedure executions while maintaining clear procedural boundaries

AI summary
Apparatuses, methods, and systems are disclosed for performing a user equipment (“UE”) parameters update (“UPU”) capability check. One method includes determining, at a first network function, to invoke a UE UPU capability check as part of a UPU procedure in response to UE capabilities not being available to provide a data set type. The method includes transmitting a first message to a second network function, wherein the first message includes: UPU priority information, UPU capability check required information, required UPU data type support information, or a combination thereof. The method includes receiving a second message from the second network function. The second message includes an authentication server function (“AUSF”) UPU medium access control (“MAC”) integrity (“I”) (“UPU-MAC-IAUSF”) and a UE UPU expected MAC (“XMAC”) I (“UPU-XMAC-IUE”).
