S101: The second network management device receives demand information of the network, where the demand information of the network carries the frequency demand information of the network or the frequency information of the network.

It should be understood that the network described here may be a combination of network functions and resources required to complete a certain (or certain) services, and is a complete logical network. Exemplarily, the 4G mobile network can be considered as one network, or the private network of a certain enterprise is one network. The network may also refer to a network slice.

Exemplarily, the demand information of the network may come from the service operation equipment as shown in FIG. 1. The service operation device may send a network allocation request message to the second network management device, and the message may carry the demand information of the network.

S102: The second network management device determines the frequency point information of the sub-network corresponding to the network according to the frequency point requirement information of the network or the frequency point information of the network.

Using the above example, the second network management device can determine the frequency point information of the sub-network according to the frequency point demand information of the network, and indicate the frequency point information of the sub-network to the first network management device. The frequency point information configures the frequency point information of the cell. Therefore, there is no need to set the corresponding frequency point information for each cell, which reduces the complexity of the process of configuring cell frequency point resources.

In S101, the frequency point requirement information of the network may include at least one of the following information: network type information, tenant information, or service type information.

In implementation, the corresponding relationship between service type and frequency point information can be configured in the second network management device in advance, for example, low-latency services correspond to the first frequency point information, and high-bandwidth services correspond to the second frequency point information, where, The first frequency point information and the second frequency point information respectively correspond to different frequency point resources. If the frequency point requirement information of the network includes information for indicating that the network supports low-latency services, the second network management device may The frequency point information is used as the frequency point information of the network, and the frequency point information of the sub-network is determined according to the first frequency point information.

Among them, LTE frequency information is applicable to cells with a cell type of LTE, such as EUTRAN cells; NR frequency information is applicable to a cell type of NR Cell, such as NRcell, NRcellCU or NRcellDU). Correspondingly, the frequency information of the sub-network may include LTE frequency information and/or NR frequency information.
