Dual-Connectivity Measurement Release After Master Link Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in handling measurement configurations when a connection failure occurs with the master node in dual connectivity scenarios, leading to unclear handling of secondary node measurements.
Innovation Solution
The communication device and network systems are designed to manage measurement configurations by releasing or maintaining measurement configurations based on detected failures with the master node, ensuring seamless operation with the secondary node through appropriate signaling and configuration adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication device keeps the second measurement configuration for measuring a second carrier of the secondary base station after detecting link failure with the master base station, then measurement continuity is maintained, but unnecessary power consumption and interference occur
Solution Approach 1:
The patent applies preliminary action by detecting link failure with the master base station before continuing measurements, and proactively releasing the second measurement configuration for the secondary base station. This prevents unnecessary power consumption by stopping measurements early when the master node connection is already failed, rather than continuing measurements that would be useless for recovery scenarios.
2Use of energy by moving object
If the communication device releases the second measurement configuration upon detecting link failure with the master base station, then power consumption is reduced, but measurement precision for secondary node recovery is lost
Solution Approach 1:
The patent performs preliminary detection of link failure with the master base station before releasing the second measurement configuration. This ensures that measurements are maintained precisely when needed (during the transition period after master node failure detection) and then released appropriately, balancing power savings with measurement accuracy for potential secondary node recovery scenarios.

AI summary
A communication device for handling a measurement configuration in a dual connectivity comprises at least one storage device for storing instructions and at least one processing circuit coupled to the at least one storage device. The at least one processing circuit is configured to execute the instructions stored in the at least one storage device. The instructions comprise establishing a first SRB; being configured a first measurement configuration by a first BS; transmitting a first measurement report to the first BS; receiving a first RRC message from the first BS; establishing a second SRB; being configured a second measurement configuration by a second BS; transmitting a second measurement report to the second BS; detecting a first failure on a first connection with the first BS; and releasing the second measurement configuration in response to the first failure on the first connection with the first BS.
