Registration Support Service for 5G Network Slice Re-registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
End devices in Next Generation (NG) wireless networks, such as 5G NR, face delays in re-registering with new network slice configuration updates, leading to uncertainty in accessing and using network slices and associated services.
Innovation Solution
A registration support service is introduced to determine the optimum time for end devices to perform re-registration procedures, generating registration support information based on analytics data to guide the end devices in updating their network slice configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If end devices wait for network slice configuration updates without active guidance, then device complexity is reduced, but loss of time increases due to uncertain re-registration timing
Solution Approach 1:
The patent introduces a registration support service as an intermediary component that receives analytics information and generates registration support information to guide end devices on when to re-register. This mediator resolves the contradiction by providing timely re-registration guidance without requiring complex device-side decision-making logic, thus reducing re-registration delay while keeping device complexity low.
Solution Approach 2:
The registration support service performs preliminary analysis of analytics information (such as network slice availability, device state, and service requirements) before the end device needs to re-register. By pre-determining the optimal re-registration timing and providing registration support information in advance, the system minimizes re-registration delay without requiring the end device to continuously monitor complex network conditions.
2Productivity
If end devices immediately re-register upon receiving configuration updates, then productivity is improved, but loss of time increases due to unnecessary re-registration procedures
Solution Approach 1:
The registration support service implements a feedback mechanism where analytics information (including network slice availability, device state, and service requirements) is continuously monitored and fed back to determine optimal re-registration timing. This feedback loop ensures that end devices re-register only when necessary and beneficial, improving productivity by ensuring quick access to needed network slices while avoiding unnecessary re-registration procedures that would waste time.
3Reliability
If a registration support service is implemented to guide re-registration, then reliability is improved, but device complexity increases
Solution Approach 1:
The registration support service acts as an intermediary that centralizes the complexity of analyzing analytics information and determining optimal re-registration timing. Instead of distributing complex decision-making logic across end devices, the service consolidates this functionality in the network, improving reliability of network slice configuration while keeping end device complexity low.

AI summary
A method, a network device, and a non-transitory computer-readable storage medium are described in relation to an registration support service. The registration support service may include providing an end device with registration support information that may facilitate a re-registration of the end device with an access and mobility management function, a mobility management entity, or the like. The registration support information may include a time period and/or a location with which the end device may initiate a registration procedure. The registration support information may be generated based on historical behavior of the end device.
