The forwarding node is further configured to receive a data packet sent by the terminal device, where the data packet includes data content, the terminal device location information, and/or the terminal device type; and determining, according to the forwarding rule table, a terminal device location information and/or a target transmission band matched by the terminal device type; establishing a communication connection with the aggregation unit on the target transmission band, and transmitting the data packet based on the established communication connection;

The aggregation unit is configured to deliver the forwarding rule table to the forwarding node;

The terminal device is configured to send the data packet to the forwarding node.
The system according to claim 6, wherein the data packet further comprises a transmission direction identifier, and the forwarding node is further configured to: after receiving the data packet sent by the terminal device, according to the data packet Transmitting the indication to the identifier, identifying whether the data packet points to the aggregation unit, and if the data packet points to the aggregation unit, performing the determining the location information and/or location of the terminal device from the forwarding rule table The target transmission band in which the terminal device type matches.
The system according to claim 6 or 7, wherein the forwarding node is configured to establish a communication connection with the aggregation unit on the target transmission frequency band, and to transmit the data packet based on the established communication connection. Specifically:

The forwarding node is configured to determine a time-frequency resource corresponding to the target transmission frequency band, and transmit the data packet to the aggregation unit on the time-frequency resource.
The system according to claim 8, wherein the forwarding node is configured to determine a time-frequency resource corresponding to the target transmission frequency band, and transmit the data packet to the aggregation unit on the time-frequency resource. The method is specifically as follows:

The forwarding node is configured to determine, by using a frequency hopping manner, a frequency domain location of a physical resource block used for transmitting the data packet from the target transmission frequency band; and corresponding to a frequency domain location of the determined physical resource block. On the time-frequency resource, the data packet is transmitted to the aggregation unit.
The system according to claim 6, wherein the data packet further comprises a terminal device identifier, and the forwarding node is further configured to: after receiving the data packet sent by the terminal device, according to the terminal device included in the data packet Identifying, by the terminal device priority list sent by the aggregation unit, the transmission priority of the terminal device, and determining the terminal from the forwarding rule table when the transmission priority of the terminal device is met The device location information and/or the target transmission band matched by the terminal device type; wherein the terminal device priority list includes a terminal device priority corresponding to a plurality of different terminal device identifiers.
