The manner in which the wireless terminal 401 reports the first reservation request for the target parking space to the parking space management platform 402 is specifically:

The wireless terminal 401 is configured to scan whether a forwarding node is preset in the surrounding environment. If a forwarding node is preset, it is detected whether the number of terminals currently accessed by the forwarding node exceeds the maximum terminal access number specified by the forwarding node; The number of currently accessed terminals does not exceed the maximum number of terminal accesses specified by the forwarding node, establishes a wireless connection with the forwarding node, and reports a reservation request for the target parking space to the forwarding node, and the forwarding node will target the target parking space. The reservation request is encrypted and sent to the parking space management platform 402.

Further, after the wireless terminal 401 is preset with the forwarding node in the scanning environment, it may first detect whether the forwarding node is configured with an open access period, and if the forwarding node is configured with an open access period, identify the current state of the wireless terminal 401. Whether the system time is located in the open access period in which the forwarding node is configured; if the current system time of the wireless terminal 401 is located in the open access period in which the forwarding node is configured, it is detected whether the number of terminals currently accessed by the forwarding node exceeds the forwarding node. Specifies the maximum number of terminal accesses; if the number of terminals currently accessed by the forwarding node does not exceed the maximum number of terminal accesses specified by the forwarding node, establish a wireless connection with the forwarding node, and report the target parking space to the forwarding node. The first reservation request is encrypted by the forwarding node to the first reservation request for the target parking space and then sent to the parking space management platform 402.

It can be seen that implementing the system described in FIG. 4 enables the driver to conveniently find the parking space for parking and improve the parking efficiency; and also allows the driver to predict the weather information of the preset time corresponding to the parking space in advance, so that the driver can do well in advance.
