Dual-SIM Paging Response Control for Service Conflict Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual SIM mobile phones experience conflicts when one communication card is in service and the other needs to be serviced, such as receiving paging or initiating services, leading to service interference.
Innovation Solution
A terminal device determines whether to respond to a paging message based on its cause, and indicates to the network that it does not respond if unnecessary, ensuring high-priority services are not affected, using explicit or implicit indication methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device responds to all paging messages, then service completeness is improved, but service conflict between dual SIM cards increases
Solution Approach 1:
The patent applies local quality by differentiating the handling of paging messages based on their specific characteristics (paging cause, priority level). Instead of uniform response to all paging messages, the terminal device selectively responds based on the local properties of each paging message, such as whether it indicates high-priority services or can be deferred, thereby resolving service conflicts while maintaining necessary service completeness
Solution Approach 2:
The patent implements dynamics by enabling the terminal device to dynamically adjust its paging response behavior based on current service state and priority conditions. The device can change its response strategy in real-time depending on whether one SIM card is actively using services, allowing flexible adaptation to avoid conflicts while ensuring critical services are not missed
2Object-generated harmful factors
If the terminal device does not respond to paging messages, then service conflict is reduced, but service reliability deteriorates
Solution Approach 1:
The patent applies feedback by implementing a mechanism where the terminal device sends indication information back to the network about its paging response status. This feedback loop allows the network to understand why the device didn't respond (e.g., due to service conflict) and adjust future paging strategies accordingly, balancing conflict avoidance with service reliability through continuous information exchange
Solution Approach 2:
The patent utilizes parameter changes by modifying the terminal device's response parameters based on paging message characteristics and service state. The device changes response parameters such as response timing, response priority, or response suppression based on factors like paging cause, current active services, and priority levels, thereby selectively maintaining reliability while avoiding conflicts
3Productivity
If the terminal device always responds to paging messages, then response completeness is improved, but processing complexity increases
Solution Approach 1:
The patent applies preliminary action by having the terminal device evaluate and prepare its response strategy before actually responding to paging messages. The device preliminarily assesses the paging cause, checks current service state, and determines the appropriate response action in advance, which simplifies the actual response execution and reduces processing complexity during critical moments
Solution Approach 2:
The patent implements partial action by having the terminal device respond only to a subset of paging messages rather than all of them. The device selectively responds based on priority and service needs, avoiding unnecessary processing for low-priority or redundant paging messages, thereby reducing overall processing complexity while maintaining response completeness for essential services

AI summary
Provided are a communication method and apparatus, a terminal device and a network device. The method comprises: a terminal device receiving a paging message sent by a first network, wherein the first network is a network corresponding to a first communication card in the terminal device; and the terminal device determining, on the basis of a paging reason in the paging message, whether to respond to the paging message, and indicating, when determining not to respond to the paging message, to the first network that the terminal device does not respond to the paging message.
