Remote-Relay Flow Mapping Synchronization in 5G Non-3GPP Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless systems, there is a lack of a mechanism to ensure synchronized remote-relay flow mapping between remote UE and relay UE when the interface is non-3GPP, leading to potential misconfiguration and inefficiencies in data transmission, especially when a SRAP entity is not available.
Innovation Solution
A method and apparatus for transmitting remote-relay flow mapping information between the remote UE and relay UE through a gNB, using configuration information with trigger conditions to synchronize the mapping between end-to-end bearer identifiers and flow identifiers over different protocol interfaces, enabling the gNB to forward this information when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote-relay flow mapping information is transmitted without a standardized mechanism, then flexibility in data transmission is improved, but mapping synchronization reliability deteriorates
Solution Approach 1:
The patent introduces a standardized information element as an intermediary carrier to transmit remote-relay flow mapping information between network elements. This standardized structure ensures reliable and synchronized mapping information delivery while maintaining flexibility in different transmission scenarios, resolving the contradiction between adaptability and reliability.
2Measurement precision
If flow mapping information is transmitted frequently to ensure synchronization, then mapping accuracy is improved, but network overhead increases
Solution Approach 1:
The patent implements periodic transmission of flow mapping information through standardized information elements at appropriate intervals or trigger events. This ensures mapping accuracy is maintained while avoiding excessive transmission frequency, thus balancing precision requirements with network overhead constraints.
3Reliability
If a standardized mechanism for flow mapping information transmission is implemented, then transmission reliability is improved, but system complexity increases
Solution Approach 1:
The patent standardizes the transmission mechanism by defining specific parameters and structures for flow mapping information elements. This standardization improves reliability through consistent formatting and processing while controlling system complexity by establishing clear, manageable parameter specifications that can be implemented across different network elements.

AI summary
A method may include receiving, from a network element over a first interface, configuration information comprising at least a trigger condition for transmission of a remote-relay flow mapping information. The method may also include determining when to transmit the remote-relay flow mapping information to the network element based on the configuration information. The method may further include transmitting, to the network element over the first interface, the remote-relay flow mapping information when the trigger condition is satisfied.
