Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a network architecture of NR, due to mobility of a user device during communication, information relating to a configuration of the user device may not be synchronized when handed over between network nodes, leading to disrupted communication.
Innovation Solution
A network node equipped with a reception unit to receive inter-node messages, a determination unit to distinguish between full and delta configurations, and an updating unit to update the user device configuration accordingly, ensuring synchronized information transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration information is handed over between network nodes during user device mobility, then communication continuity is maintained, but configuration synchronization may be lost leading to communication disruption
Solution Approach 1:
The patent applies preliminary action by having the first network node determine the update method (full or delta configuration) before actually updating the configuration. This proactive determination ensures that the configuration is updated correctly from the start, preventing synchronization loss and maintaining communication continuity during handover between network nodes.
Solution Approach 2:
The patent implements feedback by receiving inter-node messages containing configuration information from the second network node, determining the appropriate update method based on this feedback, and then updating the configuration accordingly. This feedback mechanism ensures that configuration synchronization is maintained while enabling communication continuity during mobility.
2Reliability
If full configuration is used to update user device configuration, then configuration synchronization is ensured, but resource consumption increases
Solution Approach 1:
The patent applies parameter changes by dynamically selecting between two configuration update methods (full configuration or delta configuration) based on the received inter-node message. This parameter selection optimizes resource consumption by using delta configuration when appropriate while ensuring full configuration is applied when necessary for synchronization, thus balancing reliability and energy efficiency.
Solution Approach 2:
The patent implements partial action by using delta configuration (partial update) instead of always applying full configuration. This reduces resource consumption by updating only the necessary portions of the configuration while still maintaining synchronization when needed, avoiding the excessive resource usage of always applying full configuration.
3Loss of energy
If delta configuration is used to update user device configuration, then resource consumption is reduced, but configuration synchronization may be compromised
Solution Approach 1:
The patent applies parameter changes by selectively choosing between delta configuration and full configuration based on the inter-node message received. This dynamic parameter selection allows the system to use resource-efficient delta configuration when synchronization can be maintained, while switching to full configuration when synchronization is at risk, thus balancing resource consumption and reliability.
Solution Approach 2:
The patent implements feedback by using the received inter-node message as input to determine whether to apply delta or full configuration. This feedback mechanism ensures that delta configuration is only used when it won't compromise synchronization, while automatically switching to full configuration when needed, thus maintaining reliability while reducing resource consumption.

AI summary
A network node is a first network node of a communication system including a user device and a plurality of network nodes, the network node including a reception unit that receives an inter-node message relating to a configuration of the user device from a second network node; a determination unit that determines whether a manner of updating the configuration of the user device is a full configuration or a delta configuration based on the inter-node message; and an updating unit that updates the configuration of the user device with the full configuration or the delta configuration based on the determination.
