SIM Card Registration Handling for Virtual and Physical Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
SIM cards that do not provide CS services are unable to register with data network services due to feedback information carrying a preset cause value indicating an unavailable CS domain, leading to network access issues.
Innovation Solution
A SIM card registration method that acquires the SIM card type and responds differently to feedback information based on the type, reserving data capability for virtual cards and turning off data capability for physical cards according to standard protocols, thereby avoiding network access issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal responds to feedback information carrying CS domain unavailable cause value by turning off 4G capability according to standard protocol, then the CS service requirement is met, but the data network service registration fails
Solution Approach 1:
The patent applies local quality by differentiating the response behavior based on SIM card type. For virtual SIM cards, the terminal preserves 4G capability to allow data network access, while for physical SIM cards, it turns off 4G capability to comply with CS service requirements. This localized differentiation resolves the contradiction by applying appropriate quality characteristics to different card types.
Solution Approach 2:
The patent changes the parameter of 4G capability state based on SIM card type detection. When a virtual SIM card is detected, the system maintains 4G capability enabled despite receiving CS domain unavailable feedback. This parameter change allows the terminal to bypass the standard protocol restriction and enable data network service registration for virtual SIM cards.
2Stability of the object's composition
If the terminal uniformly applies standard protocol response to all SIM cards, then protocol compliance is maintained, but virtual SIM cards cannot access data network services
Solution Approach 1:
The patent introduces dynamics by making the terminal's response behavior adaptive rather than static. The system dynamically detects SIM card type (virtual or physical) and adjusts its response to feedback information accordingly. This dynamic adaptation allows the terminal to maintain protocol compliance for physical cards while enabling data network access for virtual cards, thus resolving the contradiction between protocol stability and card type adaptability.
Solution Approach 2:
The patent segments the SIM card handling into two distinct categories: virtual SIM cards and physical SIM cards. By segmenting the response logic based on card type, the system can apply different protocols to different segments. Virtual SIM cards receive a customized response that preserves 4G capability, while physical SIM cards receive the standard protocol response, thereby achieving both protocol compliance and adaptability.
3Ease of operation
If the terminal preserves 4G capability for all SIM cards when receiving CS domain unavailable feedback, then data network service registration succeeds, but physical SIM cards violate standard protocol requirements
Solution Approach 1:
The patent applies local quality by making the 4G capability preservation selective rather than universal. The system preserves 4G capability only for virtual SIM cards that cannot provide CS services, while turning off 4G capability for physical SIM cards that require CS service compliance. This localized application of the capability preservation resolves the contradiction between data network accessibility and protocol compliance reliability.

AI summary
The present application relates to a SIM card registration method and apparatus, a computer device, and a storage medium, including: receiving a SIM card registration request, and acquiring a SIM card type corresponding to the SIM card registration request; receiving a feedback information returned according to the SIM card registration request; and responding to the feedback information according to the SIM card type when the feedback information carries preset information. In the above SIM card registration method and apparatus, the computer device, and the storage medium, by responding, according to the SIM card type, differently to information returned for a SIM card registration request, the problem that a SIM card which does not provide a CS service cannot register with a data network service when the feedback information carries preset information, leading to unable to accessing the network, can be avoided.
