Dual-SIM Paging Cause Handling for Service Coordination
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 in service, such as receiving paging or initiating services, leading to coordination issues between the two communication cards.
Innovation Solution
A terminal device determines whether to respond to a paging message based on its cause, indicating to the network that it does not respond if it decides not to, ensuring coordinated dual SIM operations by managing the services of both communication cards through a processor and memory configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device responds to all paging messages, then service completeness is improved, but coordination between dual SIM cards deteriorates
Solution Approach 1:
The patent changes the parameter of paging message response behavior by introducing selective response based on paging cause. The terminal device transitions from responding to all paging messages to responding only to specific paging messages based on their cause (e.g., voice call vs. data service), thereby resolving the coordination conflict between dual SIM cards while maintaining necessary service completion.
2Ease of operation
If the terminal device does not respond to paging messages, then coordination between communication cards is improved, but service completeness deteriorates
Solution Approach 1:
The patent implements feedback mechanism where the terminal device sends indication information to the network to inform it of the paging message non-response. This feedback allows the network to understand the terminal's intent and adjust subsequent paging behavior, ensuring that important services are not lost while maintaining coordination between dual SIM cards.
3Adaptability or versatility
If the terminal device responds to all service requests, then service availability is improved, but resource consumption increases
Solution Approach 1:
The patent applies local quality by differentiating the response behavior based on the specific characteristics of each paging message (its cause). Instead of uniform response to all paging messages, the terminal device evaluates the local characteristics of each message (voice call priority vs. data service) and responds accordingly, optimizing resource consumption while maintaining service availability for critical services.
Data Source
AI summary
Provided are a communication method, a terminal device and a chip. The method includes: a terminal device receives a paging message from a first network and service data from a second network, wherein the first network is a network corresponding to a first communication card in the terminal device, the second network is a network corresponding to a second communication card in the terminal device; and the terminal device determines whether to accept the paging message based on a paging cause in the paging message, and indicates to the first network that the terminal device does not accept the paging message in response to determining not to accept the paging message.
