Multi-Card Terminal Handover Timing for RRC Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-card mobile terminals experience service disruption and resource waste during handovers between communication systems due to uncoordinated RRC connections, leading to connection conflicts and inefficient resource utilization.
Innovation Solution
A method and apparatus that configures a time parameter for multi-card terminals to manage handovers, allowing the base station to synchronize with the terminal's handover timing and operations, thereby reducing connection conflicts and resource waste by coordinating the handover process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal stops the current RRC connection in the first communication system during handover, then the terminal can connect to the second communication system, but the service continuity is affected and connection conflicts occur
Solution Approach 1:
The network device sends indication information to the terminal before the handover is completed, indicating that the terminal should not release the first RRC connection. This preliminary action ensures that the terminal maintains the connection in advance, preventing service interruption before it can occur.
Solution Approach 2:
The network device provides feedback through indication information to control the terminal's connection release behavior. This feedback mechanism allows the network to dynamically adjust whether the terminal should maintain or release the first RRC connection based on handover status, ensuring service continuity while enabling handover.
2Reliability
If the terminal maintains RRC connection in the first communication system during handover, then service continuity is preserved, but connection conflicts occur because communication resources are already occupied
Solution Approach 1:
The network device acts as an intermediary by sending indication information to coordinate between the terminal and the first communication system. This intermediary control resolves the conflict by telling the terminal when to maintain the connection (avoiding conflicts) and when it's safe to release it (enabling handover).
Solution Approach 2:
The network device provides preliminary guidance through indication information before the handover completes, preventing the terminal from releasing the connection at inappropriate times. This preliminary control avoids connection conflicts while maintaining service continuity.
3Reliability
If the base station continues to page the terminal after disconnection, then the terminal can be reached, but paging resources are wasted
Solution Approach 1:
The network device uses feedback through indication information to control when the terminal should release the RRC connection. By providing timely feedback about handover status, the terminal can release the connection appropriately, preventing unnecessary paging and saving paging resources while maintaining reachability during the handover process.
