Serving Cell Switching and Bearer Release in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, existing mechanisms do not allow for simultaneous switching of a serving cell and release of a bearer, which hampers signaling transmission efficiency and resource management.
Innovation Solution
A method and device for switching a serving cell by transmitting a secondary node modification required message from a secondary node to a master node, enabling the master node to switch the serving cell and release the bearer, with confirmation messages ensuring efficient signaling and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing mechanisms are used for serving cell switching, then the serving cell can be switched, but the bearer cannot be released simultaneously
Solution Approach 1:
The patent combines the serving cell switching operation and bearer release operation into a single unified procedure. The master node processes both operations simultaneously based on the secondary node modification required message, eliminating the need for separate sequential operations and thereby improving signaling transmission efficiency while reducing operational constraints.
2Reliability
If serving cell switching and bearer release are performed separately, then each operation can be executed, but signaling resources are wasted
Solution Approach 1:
The patent merges the serving cell switching and bearer release into a single integrated procedure initiated by the secondary node modification required message. This combined approach ensures both operations are completed reliably while minimizing signaling resource consumption by avoiding duplicate messaging and processing overhead.
Solution Approach 2:
The master node prepares and executes both the serving cell switching and bearer release operations in advance based on the received modification required message, rather than performing them sequentially after separate signaling exchanges. This preliminary combined action reduces overall signaling resource usage while maintaining operational reliability.
