Disaggregated UE Protocol Stacks for Flexible Secure Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for further improvements in 5G NR technology to enhance communication systems, particularly in establishing and managing connection sessions between user equipment (UEs) with improved security and routing protocols, especially in scenarios involving disaggregated UE architectures.
Innovation Solution
A method and apparatus at a UE are configured to establish a connection session based on a configuration profile that includes a mapping of upper-layer protocols to lower-layer protocols, security policies, and routing for services, enabling management of connections between UEs and third devices through a protocol stack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a disaggregated UE architecture is implemented to improve connection management flexibility, then the adaptability of the system is improved, but the device complexity increases due to multiple protocol stacks and connection management entities
Solution Approach 1:
The UE is divided into multiple functional entities including a first protocol stack for cellular communication and a second protocol stack for non-cellular communication. These protocol stacks are segmented into independent modules that can be selectively activated based on communication requirements, allowing flexible connection management while maintaining manageable complexity through modular design
Solution Approach 2:
The first UE is configured to perform multiple functions including acting as a relay for the second UE, managing connections to third devices, and handling both cellular and non-cellular communications. This multi-functionality allows a single device to manage diverse connection types through unified configuration profiles that define protocol mappings and routing rules
2Reliability
If security policies are enforced in disaggregated UE connections, then the reliability is improved, but the ease of operation decreases due to additional configuration requirements
Solution Approach 1:
Security policies, protocol mappings, and routing rules are pre-configured in configuration profiles before actual communication occurs. The first UE and second UE are provisioned with these profiles in advance, which automatically apply security measures and establish protocol relationships when connections are formed, reducing the operational burden during actual communication setup
Solution Approach 2:
The configuration profile acts as an intermediary that encapsulates complex security policies and protocol mappings. Instead of directly managing complex security handshakes and protocol negotiations, the UEs utilize these pre-defined profiles that automatically enforce security requirements while simplifying the connection establishment process

AI summary
Apparatus, methods, and computer program products for disaggregated UE are provided. An example method includes establishing, with a second UE, a connection session based on a configuration profile, the configuration profile including a mapping of an upper-layer protocol to a lower-layer protocol, one or more security policies, and a routing for one or more services associated with the second UE to a protocol stack. The example method further includes managing a connection between the second UE and a third device via the connection session.
