Mobile Communication Controller Cell Reselection Resource Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a mobile communication terminal performs cell reselection from a first communication system to a second, the communication resource of the first system remains reserved, leading to redundant resources.
Innovation Solution
A mobile communication controller is configured to receive a control signal from the terminal indicating its previous system and transmit an instruction to release the communication resource of the first system, ensuring resources are freed before switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile communication terminal performs cell reselection from the first communication system to the second communication system, then the terminal can switch to a more suitable communication system, but the communication resource of the first communication system remains reserved as a redundant resource
Solution Approach 1:
The terminal transmits the control signal indicating previous system location before actually switching systems. The second communication system then proactively releases resources from the first system in advance, preventing resource redundancy before it occurs.
Solution Approach 2:
The terminal provides feedback information (control signal) about its previous system location to the second communication system. This feedback enables the second system to take appropriate action to release resources from the first system, optimizing resource management.
2Reliability
If the communication resource of the first communication system remains reserved until the terminal requests release, then the terminal maintains service continuity, but the communication resource becomes a redundant resource
Solution Approach 1:
The terminal feeds back information about its cell reselection to the second communication system, which then actively manages resource release in the first system. This feedback mechanism enables proactive resource optimization while maintaining service continuity.
Solution Approach 2:
The second communication system autonomously initiates the resource release process in the first system based on the terminal's control signal, without waiting for the terminal to explicitly request resource release. This self-service approach optimizes resource utilization while maintaining service continuity.

AI summary
A mobile communication terminal 10 is configured to transmit a control signal indicating a request for cell reselection to the second communication system to the first communication system before a communication resource of the second communication system is reserved while the mobile communication terminal was located in the first communication system. The first communication system releases a communication resource of the first communication system in response to the control signal indicating the request for cell reselection to the second communication system even before the communication resource of the second communication system is reserved.
