Terminal Mode Switching for Silent Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a mobile phone is switched to an offline mode, it enters a power-off state relative to the network, preventing both CS domain call and short message services and PS domain network data services from being used.
Innovation Solution
A mode switching method and device that switches the terminal's working mode to a target state where the CS domain service is disconnected and the PS domain service remains connected, allowing network data services to be used even when the terminal cannot receive calls or short messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mobile phone is switched to an offline mode to prevent receiving calls and short messages, then the user is free from answering calls or receiving short messages, but network data services in the PS domain cannot be used either
Solution Approach 1:
The patent segments the network services into two independent domains: CS domain for voice and short message services, and PS domain for data services. By selectively disconnecting only the CS domain while maintaining PS domain connectivity, the system allows users to block calls and messages without affecting data services like Internet access and stream media.
Solution Approach 2:
The patent introduces a dynamic mode switching mechanism that allows the terminal to transition between different working modes (online mode, offline mode, and silent mode). In the silent mode, the system dynamically maintains PS domain connectivity while disconnecting CS domain services, enabling flexible adaptation to user needs without sacrificing data service capability.
2Reliability
If the terminal switches to offline mode to block CS domain services, then calls and short messages cannot be received, but the terminal also cannot access PS domain network services
Solution Approach 1:
The patent implements a dynamic mode switching mechanism with three distinct modes: online mode (both CS and PS domains connected), offline mode (both domains disconnected), and silent mode (CS domain disconnected while PS domain remains connected). This dynamic approach allows users to select the silent mode when they want to block calls and messages while maintaining data service access, resolving the contradiction between reliability of blocking and ease of accessing network services.
Solution Approach 2:
The system segments the network connectivity control into independent CS domain and PS domain management. By controlling each domain separately through selective detach procedures, the system enables the silent mode where CS services are blocked while PS data services remain accessible, improving ease of operation without compromising the reliability of call and message blocking.
3Object-affected harmful factors
If the terminal enters a power-off state relative to the network to block all services, then no calls or messages are received, but data services are also unavailable
Solution Approach 1:
The patent divides network service management into separate CS domain and PS domain controls. Instead of a complete power-off state that blocks all services, the silent mode selectively powers off only the CS domain while maintaining PS domain connectivity. This segmentation allows the terminal to block harmful factors (calls and messages) while preserving useful functionality (data services), thereby improving adaptability and versatility.
Solution Approach 2:
The system employs dynamic mode switching between online, offline, and silent modes. The silent mode represents a dynamic intermediate state where the terminal is partially powered off relative to the network - specifically disconnecting CS services while maintaining PS services. This dynamic approach resolves the contradiction by providing selective service availability rather than an all-or-nothing power-off state.

AI summary
The present invention discloses a mode switching method and device, relating to the field of terminal technologies and solving the problem that when a terminal is switched to an offline mode, the terminal is in a power-off state relative to a network, so in addition to that calls and short messages in a CS domain service cannot be received, network data services in a PS domain service cannot be used as well. The technical solution of the present invention includes: receiving a first switching instruction for switching a working mode of a terminal to target mode; switching the working mode of the terminal to the target mode according to the first switching instruction, where the target mode indicates that a circuit switch CS domain service is in a disconnected state, and a packet switch PS domain service is in a connected state. Embodiments of the present invention are mainly applied in a mode switching process.
