If the signal of the connecting device directly connected with the cellular network is detected to be weak or has large fluctuation, the signal enhancement or relay function is automatically triggered. When the signal of the cellular network of the connection equipment is detected to be weak or has large fluctuation, the signal is enhanced by the vehicle-mounted antenna to realize the forwarding.

The information transceiving frequency may be the number of times the connection device transmits and receives information per unit time.

The release timing may be a specific timing at which the relay state is determined to be released.

Specifically, a wireless module of the vehicle-mounted system is used for continuously monitoring the signal intensity of the direct connection or relay connection of the connection equipment to the cellular network, and recording the signal intensity data for subsequent analysis. Setting a threshold value of signal strength, when the signal strength of the connection apparatus is higher than this threshold value, the relay state may be considered to be released. And comparing the signal strength monitored in real time with a threshold value to determine whether to release the relay state. If the relay release state is determined, a request is sent to the connecting device, and the operation data of the connecting device, such as the device state, the network connection condition, the application program operation condition and the like, is acquired. And receiving the operation data returned by the equipment and preparing for subsequent analysis. Analyzing the equipment operation data, and extracting key indexes related to information transceiving, such as the number, the size, the frequency and the like of transceiving data packets. These indices are analyzed to determine the information transmission/reception frequency of the device. And judging the most suitable time for releasing the relay state according to the information receiving and transmitting frequency and other related indexes (such as network delay, equipment load and the like). And at the determined time, performing an operation of releasing the relay state, so that the connecting device is restored to the direct-connection cellular network.

In some embodiments, whether an unfinished transceiving flow exists is determined according to a release opportunity, if so, a temporary storage flow area is started to temporarily store information corresponding to the unfinished transceiving flow according to the unfinished transceiving flow, and the temporarily stored information is transmitted and received after relay release.

The transceiving flow may be the entire process of transmitting data from a sender to a receiver in network communication.

The temporary flow area may be an area for temporarily storing data in the connection device during network communication.

Specifically, the receiving and transmitting processes of the connection device are monitored in real time, and the state of each process is recorded, including starting, neutralizing and ending. When a predetermined release timing is reached, it is checked whether or not there is an ongoing but not yet completed transmission/reception flow. If the unfinished transceiving flows exist, starting to allocate a temporary storage area in a memory or storage for each unfinished transceiving flow. The information in the unfinished flow is temporarily stored in the corresponding temporary storage area, so that the information is ensured not to be lost due to the release of the relay state. A relay release operation is performed to cause the connected device to communicate directly with the cellular network. After the release operation from the relay is completed, the information in the temporary storage area is restored. And retransmitting or receiving the information according to the temporarily stored transceiving flow, so as to ensure that each flow can be completely executed.

By means of the scheme, the states of all communication flows are ensured to be accurately reflected through real-time monitoring and recording. When the release time comes, the detection of the unfinished flow is carried out, so that the relay is prevented from being released at the key communication time, and the communication continuity is ensured. And a temporary storage area is allocated for each unfinished transceiving flow, so that the data security is ensured, and the communication interruption caused by relay release is prevented. By starting the temporary storage flow area, a data basis is provided for the subsequent flow recovery, and the communication flow can be ensured to be continued seamlessly. And immediately processing the temporarily stored information after the relay is released, so as to ensure that all communication flows can be properly processed. And the use of network resources is optimized and the communication efficiency is improved by recovering and completing the temporary storage receiving and transmitting flow.

In some embodiments, determining whether to start vehicle-mounted forwarding according to the detection result includes obtaining a packet loss threshold and a delay threshold, determining signal quality of the connection device according to the packet loss threshold, the packet loss rate, the delay threshold and the delay condition, and determining whether to start vehicle-mounted forwarding according to the signal quality.

The packet loss threshold may be the highest acceptable proportion of packets lost during the data communication.

The delay threshold may be a maximum delay time allowed for the transmission of the data packet from the sender to the receiver.

The signal quality may be an overall performance of the wireless network or the communication link, and may also have indicators of multiple dimensions, such as packet loss rate, delay, etc.

Specifically, thresholds for packet loss rate and delay are defined based on network quality requirements and communication standards. And acquiring a preset packet loss threshold value and a preset delay threshold value from network configuration or system setting. The packet loss rate of the connected device, i.e. the rate at which data packets are lost during transmission, is monitored. The delay of the connection device, i.e. the transmission time of the data packets from the sender to the receiver, is monitored. And comparing the monitored packet loss rate and the monitored delay with a threshold value, and evaluating the signal quality. And according to the signal quality evaluation result, applying decision logic to determine whether vehicle-mounted forwarding needs to be started. If the signal quality is lower than the threshold value, starting vehicle-mounted forwarding, and if the signal quality meets the requirement, maintaining the current state.
