Frequency Priority Updates for Mobility Across Validity Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communications networks, such as NR networks, face challenges in managing priority configurations that vary by area and network slice, leading to incorrect frequency priority configurations when devices move between locations.
Innovation Solution
Implementing methods and systems that enable devices to receive and apply new priority configurations when moving out of validity areas, using dedicated signaling to manage frequency and network slice preferences, and enabling network apparatus to collect and transmit validity area information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If priority configurations are assigned to apparatus for specific validity areas, then network slice and frequency priority management is improved, but when apparatus moves out of validity areas, incorrect priority configurations are applied
Solution Approach 1:
The system dynamically updates priority configurations based on the apparatus's current location relative to validity areas. When moving between validity areas, the apparatus receives updated priority configurations from the network, ensuring that the applied priorities always match the current geographical context rather than using static configurations.
Solution Approach 2:
The apparatus monitors its own location and detects when it moves out of a validity area. This self-detection triggers a feedback mechanism where the apparatus requests and receives updated priority configurations from the network, ensuring continuous accuracy of priority settings based on current location.
2Reliability
If validity area information is transmitted via dedicated signaling, then priority configuration management is improved, but network signaling overhead and complexity increase
Solution Approach 1:
The dedicated signaling mechanism is designed to serve multiple functions: it delivers validity area information, transmits priority configurations, and enables mobility management all through the same signaling pathway. This multi-functionality reduces the need for separate dedicated protocols for each function.
Solution Approach 2:
The network acts as an intermediary that manages the complexity of priority configuration delivery. Instead of the apparatus having to actively query or manage its own configurations, the network proactively provides updated configurations through dedicated signaling when the apparatus moves between validity areas, centralizing the management complexity in the network infrastructure.

AI summary
Examples of the disclosure relate to an apparatus configured to enable priority configurations to be updated. The apparatus can be configured to perform receiving information indicative of at least one validity area for the apparatus wherein the at least one validity area comprises includes an area in which priority configurations assigned to the apparatus are valid; detecting that the apparatus has moved out of the at least one validity area; in response to detecting that the apparatus has moved out of the at least one validity area performing at least one of: receiving at least one new priority configuration and following the at least one new priority configuration, or triggering a state change to a connected mode to obtain at least one new priority configuration from an access node.
