Solution Overview
Problem
Vehicle-mounted communication devices experience rapid power loss when parked in non-network areas for extended periods, leading to unnecessary trouble for vehicle owners due to continuous searching for network frequency points, which increases power consumption.
Innovation Solution
A network connection method and apparatus that extracts and stores network frequency points during vehicle operation, allowing cyclic search and connection based on signal strength, with options to limit storage and adjust search intervals to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle-mounted communication device continuously searches for network frequency points when parked, then the device can maintain network connection capability, but the power consumption increases rapidly
Solution Approach 1:
The patent implements periodic searching instead of continuous searching by setting a search interval (e.g., every 5 minutes) for scanning network frequency points. This periodic action maintains network connection capability while significantly reducing power consumption during parked states, directly resolving the contradiction between reliability and energy usage.
Solution Approach 2:
The patent stores previously searched and valid network frequency points in a local database before the vehicle is parked. When parked, the device can directly use these pre-stored frequency points for connection without immediate searching, maintaining network capability while avoiding the energy-intensive continuous search process.
2Reliability
If the device increases transmitting power to find a base station with stronger signal, then the network connection reliability improves, but the power consumption increases
Solution Approach 1:
The patent implements a tiered transmitting power strategy where the device uses lower transmitting power for initial connection attempts and only increases power when necessary to find a base station with adequate signal strength. This partial action approach maintains network reliability while minimizing unnecessary energy expenditure from continuously high power transmission.
3Speed
If the device searches for network frequency points at short intervals, then the network connection response speed improves, but the power consumption increases
Solution Approach 1:
The patent dynamically adjusts the search interval based on the vehicle's state and network conditions. When the vehicle is moving or network conditions require frequent updates, shorter intervals are used for faster response. When parked or in stable network conditions, longer intervals reduce power consumption. This dynamic adjustment resolves the contradiction between connection speed and energy usage.

AI summary
The present application discloses a network connection method and apparatus, an electronic device, and a storage medium. The method includes: if it is detected that a vehicle is in a stalled state, extracting a network frequency point table from a frequency point storage area, where the network frequency point table at least includes one network frequency point, and the network frequency point is acquired and stored in the network frequency point table after the vehicle is started; cyclically searching for each network frequency point in the network frequency point table; determining a current network signal strength corresponding to each network frequency point; determining, according to the current network signal strength corresponding to each network frequency point, a target network frequency point to be connected; and connecting to the target network frequency point, and then performing data interaction. In this way, when the vehicle is parked, the vehicle does not need to consume more power to search for a new network frequency point again, thereby prolonging the operating time of a device when the vehicle is parked, such that a vehicle owner remotely monitors the vehicle by means of a mobile terminal.
