Dual-Card Terminal Network Switching for Service Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-card mobile phones face service conflicts when one communication card is active and the other needs to perform a service, such as receiving a paging message or initiating a service, due to the lack of effective coordination between the two communication cards.
Innovation Solution
A method where a terminal device receives a paging message or initiates an RRC connection establishment procedure with one network and transmits indication information to the second network to request leaving that network, allowing the device to communicate with the first network while suspending services on the second network, ensuring mutual coordination of dual-card operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device communicates with one network, then the communication service on that network is maintained, but the service on the other network is blocked
Solution Approach 1:
The patent implements dynamic network switching by detecting service states of both communication cards and automatically adjusting network connectivity. When one card needs to communicate, the system dynamically suspends the other card's network connection, then restores it after the service completes. This dynamic adjustment resolves the contradiction by making the system adaptable (improving versatility) while maintaining reliable communication (improving reliability) through real-time state monitoring and switching.
Solution Approach 2:
The system changes the operational parameters of the communication cards by transitioning them between active and suspended states. When a service conflict is detected, the parameter (network connection state) of the non-active card is changed from connected to suspended, allowing the active card to communicate without interference. After service completion, the parameter is restored. This parameter change approach enables the system to maintain reliability while adapting to different service requirements.
2Speed
If the terminal device suspends service on one communication card to communicate with the other network, then communication delay is reduced, but service interruption occurs
Solution Approach 1:
The system performs preliminary actions by detecting when a communication service is needed on one card and proactively suspending the other card's network connection before the service begins. This preliminary suspension prevents potential communication delays that would occur if both cards tried to use the network simultaneously. After the service completes, the system automatically restores the suspended card's connection. This preliminary action approach reduces communication speed issues while minimizing service interruption time through automated restoration.
3Adaptability or versatility
If the terminal device maintains dual-network connectivity, then service versatility is improved, but service conflicts occur
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors the service states of both communication cards. When the system detects that one card needs to communicate while the other is also attempting network access, it provides feedback by suspending the non-active card's network connection. This feedback loop ensures that service conflicts are resolved automatically, maintaining reliability while preserving dual-card versatility. The system monitors for service completion and provides feedback to restore connections accordingly.

AI summary
Embodiments of the present application provide a method and apparatus for negotiating communication, and a terminal device. The method comprises: a terminal device receives a paging message sent by a first network or a terminal device triggers to initiate a radio resource control (RRC) connection establishment procedure to a first network, the first network being a network corresponding to a first communication card in the terminal device; and the terminal device sends first indication information to a second network, the first indication information being used for indicating the terminal device to request to leave the second network to communicate with the first network, and the second network being a network corresponding to a second communication card in the terminal device.
