Current network switching technologies in mobile communication systems lack reliability due to the terminal's inability to obtain sufficient information about cellular communication networks before switching, often resulting in invalid network switches and poor data transmission reliability.
Innovation Solution
A communication method and apparatus where a wireless access point acquires and transmits network information to a terminal, allowing the terminal to determine compatible cellular communication networks and enabling the access point to select a target network for switching based on communication quality thresholds, ensuring valid network switching and improved reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal performs network switching without obtaining sufficient cellular network information, then the switching operation is simple and fast, but the reliability of network switching deteriorates due to invalid switches
Solution Approach 1:
The access point performs preliminary actions by acquiring cellular network information and transmitting it to the terminal before network switching occurs. This allows the terminal to obtain necessary network type information in advance, enabling reliable network switching without requiring the terminal to perform complex independent detection
Solution Approach 2:
The access point acts as an intermediary between the cellular network and the terminal. It acquires cellular network information, processes it, and transmits relevant network type information to the terminal through management frames, thereby enabling the terminal to make informed switching decisions without direct complex interactions with the cellular network
2Reliability
If the terminal detects cellular networks independently, then the terminal has full control over network selection, but the probability of successful switching deteriorates due to lack of access point network information
Solution Approach 1:
The access point serves as a mediator that bridges the terminal and cellular network information. It acquires cellular network information, filters and processes it, and transmits relevant network type information to the terminal through management frames, enabling reliable switching without complicating terminal operations
Solution Approach 2:
The system implements feedback by having the terminal send connection establishment requests based on the network information received from the access point. The access point uses this feedback to determine whether to send network switching instructions, creating a closed-loop control that improves switching reliability while maintaining operational simplicity
3Reliability
If the access point transmits network information to the terminal, then the terminal can make informed switching decisions, but the communication protocol complexity increases
Solution Approach 1:
The management frame structure is designed with multi-functionality, serving both as a standard wireless communication management frame and as a vehicle for transmitting cellular network information. By utilizing existing frame structures and adding optional information elements, the solution avoids creating entirely new complex protocols while enabling reliable network switching
