Network Access Control for Terminal Data Connection Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices experience network connection errors or runtime errors when attempting to establish data connections to multiple networks simultaneously, leading to impaired data transmission.
Innovation Solution
A network access control method where a first network device determines the existence of a second data connection in a terminal device and instructs it to either stop or end the second connection to ensure a single active data connection, preventing errors by controlling the establishment of the first data connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal device forcibly establishes a data connection to another network when already connected to one network, then network access versatility is improved, but network connection stability deteriorates causing errors
Solution Approach 1:
The network device performs preliminary checking of the terminal device's connection status before allowing establishment of a new data connection. By proactively detecting whether the terminal is currently in a connected state to another network, the system prevents conflicting connection attempts and maintains connection stability while still allowing versatile network access when appropriate.
Solution Approach 2:
The network device receives feedback about the terminal device's current connection status and uses this information to control whether to permit establishment of a new data connection. This feedback mechanism ensures that the terminal device can access multiple networks selectively without causing connection errors, resolving the contradiction between versatility and stability.
2Adaptability or versatility
If a terminal device establishes data connections to multiple networks simultaneously, then network access capability is improved, but data transmission reliability deteriorates
Solution Approach 1:
Before establishing a new data connection, the network device performs preliminary verification to check if the terminal device already has an active data connection to another network. This advance checking prevents the terminal from being in a conflicting state where it cannot normally transmit data, ensuring transmission reliability while maintaining the capability to access multiple networks sequentially.
Solution Approach 2:
The system implements feedback control by monitoring the terminal device's connection status and using this information to regulate establishment of new data connections. This ensures that the terminal device maintains proper connection states for reliable data transmission while preserving the ability to access different networks as needed.
3Productivity
If the terminal device is in connected state in LTE network, then data transmission is enabled, but access to SALTE network is blocked
Solution Approach 1:
The network device performs preliminary detection of the terminal device's LTE connection status before processing SALTE network access requests. By checking in advance whether the terminal is in a connected state in the LTE network, the system can appropriately manage the access request to prevent runtime errors while maintaining productivity when connections are valid.
Solution Approach 2:
The system uses feedback from the terminal device's connection status to control network access decisions. When the terminal is determined to be in a connected state in LTE network, the feedback mechanism regulates SALTE network access to prevent conflicts, thereby maintaining both data transmission efficiency and network access flexibility under appropriate conditions.

AI summary
A network access control method and an apparatus are disclosed. The method includes controlling, by a first network device if determining that a terminal device already establishes a second data connection to a second network, the terminal device to stop establishment of a first data connection to a first network, or controlling the terminal device to end the second data connection, to smoothly establish a first data connection. In this way, it can be ensured that a data connection exists between the terminal device and one network, and it can be ensured that the terminal device can normally transmit data.
