Standalone Non-Public Network Access via Subscription Compatibility Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing access to standalone non-public networks (SNPNs) by user equipment (UEs) that are not subscribed, leading to unnecessary resource consumption and registration attempts that are not permitted.
Innovation Solution
UEs determine whether they can access an SNPN using a subscription for another network by comparing received SNPN identifiers with stored configurations or network identifiers, allowing them to select the appropriate subscription for registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If UEs attempt to register with SNPNs without checking subscription compatibility, then access control is simplified, but unnecessary resource consumption and unauthorized access attempts increase
Solution Approach 1:
The UE performs preliminary actions by determining SNPN accessibility and comparing subscription credentials before attempting registration. This preliminary check prevents wasted registration attempts on incompatible networks, resolving the contradiction by simplifying the actual access process while conserving network resources.
Solution Approach 2:
The UE autonomously determines its own accessibility to SNPNs by comparing its subscription credentials with received SNPN identifiers. This self-service mechanism eliminates the need for complex centralized access control checks, simplifying the process while preventing resource waste from unauthorized attempts.
2Loss of energy
If UEs check subscription compatibility before SNPN access, then resource consumption is reduced, but access control complexity increases
Solution Approach 1:
The patent extracts the essential access control function into a simple credential comparison operation. By taking out only the necessary SNPN identifier comparison from the complex registration process, the system reduces resource consumption while maintaining minimal access control complexity.
Solution Approach 2:
The preliminary determination of SNPN accessibility is performed as a simple preparatory step before full registration. This separates the complex authentication process from the initial access decision, reducing both resource consumption and perceived complexity for the user.
3Speed
If UEs perform registration attempts without preliminary accessibility determination, then access process is faster, but unauthorized access attempts and resource waste increase
Solution Approach 1:
A brief preliminary determination step is added before registration to check SNPN accessibility. While this adds a small initial delay, it prevents multiple failed registration attempts, ultimately improving overall network efficiency and reducing wasted resources.
Solution Approach 2:
The UE quickly skips incompatible SNPNs by performing rapid identifier comparison and moving on to compatible networks. This rushing through incompatible options prevents time-wasting failed registrations while maintaining overall process efficiency.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a standalone non-public network (SNPN), to which the UE is not subscribed, permits access to subscribers of a network to which the UE is subscribed. The UE may register with the SNPN based at least in part on a determination that the SNPN permits access to subscribers of the network to which the UE is subscribed. Numerous other aspects are provided.
