The first function instance and the second function instance may be two network entities or one network entity, respectively, and for simplicity, the first network function is taken as an example of one network entity in the following embodiments.

In one embodiment, the second network function determines whether unicast is mixed in the first service through the acquired service configuration after receiving service information sent by the terminal or the fourth network function. Wherein the service configuration may be obtained by local configuration or from a network entity UDM/UDR implementing unified data management and unified data storage.

And the second network function acquires unicast information and multicast information of the first service under the condition that the first service is mixed with unicast. The second network function may acquire the unicast information and the multicast information of the first service in various manners, and may acquire the unicast information and the multicast information of the first service from the first network function and/or the third network function, and in this embodiment of the present application, only three embodiments of the present application are given for illustration:

In another embodiment, the second network function sends the service information to a third network function, the third network function sends the service information to the first network function, and the unicast information and the multicast information of the first service are obtained from the first network function and then sent to the second network function.

In another embodiment, the two embodiments are combined, the second network function obtains the unicast information of the first service from the first network function, and the third network function obtains the multicast information of the first service from the first network function and forwards the multicast information to the second network function.

After the second network function obtains the unicast information and the multicast information of the first service, the second network function sends the resource information of the first service to the base station; the resource information is used for distributing unicast resources corresponding to the unicast information and indicating shared resources corresponding to the multicast information, and the unicast resources corresponding to the unicast information are used for transmitting unicast data.

The manner in which the second network function sends the resource information of the first service to the base station may be divided into two processes, that is, sending the resource information corresponding to the unicast information and the resource information corresponding to the multicast information to the base station, respectively.

After acquiring the resource information of the first service, the base station establishes a data channel of the first service according to the resource information, wherein the data channel comprises unicast resources corresponding to the unicast information and shared resources corresponding to the multicast information.

It should be understood that, in the unicast data and the multicast data of the first service, the unicast resource corresponding to the unicast information is used for transmitting the unicast data, and cannot be used for transmitting the multicast data of the first service or cannot be used for transmitting the multicast data including the multicast data of the first service.

The method comprises the steps that a shared resource corresponding to multicast information is possibly established, and if the shared resource is not established, a base station establishes the shared resource corresponding to the multicast information according to the resource information; if the shared resource is already established, the shared resource is used according to the resource information, and the establishment process does not need to be repeated.
