Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dual connectivity technology in wireless communications faces inefficiencies in activation and deactivation, leading to delays and disruptions in communication services, particularly when switching between primary and secondary SIM cards.
Innovation Solution
A dual connectivity management method where the terminal device actively requests to deactivate or activate dual connectivity by sending messages to the network devices, maintaining RRC connections, and suspending or resuming communication with secondary cells without releasing RRC connections or radio links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the master network device controls release and establishment of communication connection between terminal device and secondary network device using RRC reconfiguration message, then dual connectivity deactivation or activation is completed, but large delay exists and terminal device cannot quickly deactivate or activate dual connectivity
Solution Approach 1:
The terminal device performs preliminary actions by autonomously deactivating or activating dual connectivity before network confirmation. The terminal device sends a first message to the first network device to indicate or request deactivation or activation, and executes the deactivation or activation based on this indication without waiting for complete RRC reconfiguration, thereby reducing delay and improving efficiency
Solution Approach 2:
The terminal device serves itself by autonomously determining and executing dual connectivity deactivation or activation based on network indication in the first message, rather than passively waiting for the network device to complete the entire reconfiguration process. This self-service approach allows the terminal device to quickly respond to dual connectivity changes without being bottlenecked by lengthy network-controlled procedures
2Productivity
If the terminal device releases RRC connection or radio link between terminal device and second network device to deactivate dual connectivity, then dual connectivity is deactivated, but service continuity is disrupted and activation cannot be quick
Solution Approach 1:
The terminal device performs preliminary deactivation or activation of dual connectivity while maintaining the RRC connection and radio link with the second network device. By executing the deactivation or activation before releasing connections, and based on indication in the first message, the terminal device ensures service continuity is maintained throughout the transition, allowing for quick reactivation without connection re-establishment delays
Solution Approach 2:
The terminal device autonomously manages dual connectivity state changes while preserving underlying connections. The terminal device determines to deactivate or activate dual connectivity based on network indication and executes this while maintaining RRC connections, thereby self-managing the connectivity state without disrupting service continuity or requiring connection re-establishment
