Remote Configuration Mode Determination for User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote configuration methods for User Equipment (UE) in Standalone Non-Public Networks (SNPN) lack support for Subscription Owner SNPNs and incur increased signaling overhead due to independent capability negotiation, leading to failures in determining the appropriate remote configuration mode.
Innovation Solution
A method and apparatus for remotely configuring UE by sending a registration request to a core network device, receiving an available remote configuration mode determined by supported modes from both the first and second networks, and performing configuration accordingly, thereby selecting the appropriate configuration mode and improving flexibility and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If independent capability negotiation is performed for each network, then network-specific configuration accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent combines capability negotiation for multiple networks into a single unified process. The UE sends one registration request that includes capability information for both the first network and second network, and the core network device determines the appropriate remote configuration mode by comparing capabilities across both networks simultaneously. This merging approach reduces the number of separate negotiation exchanges while still achieving accurate configuration by considering all network capabilities together.
Solution Approach 2:
The registration request message is designed to serve multiple functions: it registers the UE with the current network, conveys capability information for multiple networks (first and second networks), and enables the core network device to determine the appropriate remote configuration mode. This multi-functional message structure eliminates the need for separate capability negotiation messages for each network, reducing signaling overhead while maintaining configuration accuracy.
2Measurement precision
If remote configuration mode is determined independently for each network, then mode determination accuracy is improved, but configuration flexibility deteriorates
Solution Approach 1:
The core network device merges capability information from both the first network and second network into a single evaluation process. By comparing UE capabilities against both network capabilities simultaneously, the system determines a remote configuration mode that is accurate for both networks, enabling the UE to operate correctly in either network without requiring separate mode determinations. This approach maintains mode determination accuracy while significantly improving configuration flexibility and adaptability.
3Reliability
If multiple capability negotiation messages are exchanged, then configuration reliability is improved, but communication efficiency deteriorates
Solution Approach 1:
The UE includes all necessary capability information for multiple networks in the initial registration request message, before any remote configuration takes place. This preliminary inclusion of capability data eliminates the need for subsequent back-and-forth capability negotiation messages, reducing the number of communication exchanges while ensuring that the core network device has all the information needed to reliably determine the appropriate configuration mode.

AI summary
The present disclosure provides a remote configuration method of a UE, an apparatus, and a communication device. The method includes: sending a registration request to a first core network device of a first network by means of a UE; the UE receiving an available remote configuration mode sent by the first core network device, wherein the available remote configuration mode is determined by a remote configuration mode supported by the first network and/or by a remote configuration mode supported by a second network; and the UE performing remote configuration according to the available remote configuration mode.
