Dual-Network UE Service Continuity With Priority Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) cannot simultaneously receive services from both a non-public network (NPN) and a public network (PN) with overlapping coverage areas, particularly when both networks require low latency and high data rates, leading to service access and paging issues.
Innovation Solution
A method and system for UE to register with both networks, transmit priority messages, and switch services based on priority indications, allowing concurrent service provision from one network through the other, with resource allocation and traffic pattern adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE camps in the NPN to receive service from the NPN, then the service from the NPN is provided to the UE, but the UE cannot access service from the PN and cannot be paged by the PN
Solution Approach 1:
The patent segments the service reception mechanism by introducing a priority indication message that divides the service delivery path into NPN primary service and PN secondary service components. The UE can simultaneously maintain registration with both networks while the priority indication mechanism segments the active service reception based on network priority levels.
Solution Approach 2:
The priority indication message acts as an intermediary mechanism between the NPN and PN. When the UE camps in the NPN, the priority indication message from the PN serves as a mediator to enable the UE to still access PN services and receive PN paging messages without leaving the NPN camped state.
2Reliability
If the UE camps in the PN to receive service from the PN, then the service from the PN is provided to the UE, but the UE cannot access service from the NPN and cannot be paged by the NPN
Solution Approach 1:
The patent applies segmentation by introducing priority indication messages that can be transmitted in both directions (PN to NPN and NPN to PN). This allows the system to segment service reception based on which network has higher priority at any given time, enabling the UE to maintain camped status in one network while still accessing services from the other network through priority-based routing.
Solution Approach 2:
The priority indication message serves as a bidirectional intermediary mechanism. When the UE camps in the PN, the priority indication message from the NPN acts as a mediator to enable the UE to access NPN services and receive NPN paging messages while remaining camped in the PN.
3Adaptability or versatility
If priority services are provided from both networks simultaneously, then service diversity is improved, but network complexity and resource allocation difficulty increase
Solution Approach 1:
The patent applies parameter changes by using priority indication messages that carry priority level information as a key parameter. This allows the network to manage multiple concurrent services by changing and monitoring priority parameters, which simplifies the resource allocation process compared to managing equal-priority services from multiple networks.
Solution Approach 2:
The priority indication message mechanism provides feedback to the UE about which network services have higher priority. This feedback loop enables the UE to automatically adjust its service reception behavior, reducing the network management complexity by allowing the UE to handle priority decisions locally rather than requiring complex centralized coordination.
