s302, configuring multicast group information of a virtual network group, wherein the virtual network group comprises: and one or more multicast groups, wherein each multicast group corresponds to one multicast address, and the multicast group information at least comprises the multicast address of each multicast group and corresponding QoS information.
It should be noted that, in the multicast network, different application data sets different multicast addresses, which may be received by a set of designated user terminals. Since the unused application data may have different QoS information, in order to implement different QoS for different multicast group communications within one virtual network group, qoS information corresponding to each multicast group needs to be preconfigured and stored in association with the configured QoS information and multicast address.
In some embodiments, the virtual network Group in embodiments of the present disclosure may be, but is not limited to, a 5G VN Group of a 5G communication system.
In some embodiments, when the virtual network Group in the embodiments of the present disclosure is a 5G VN Group, S302 described above may configure multicast Group information of the virtual network Group into the UDR network element. Specifically, this can be achieved by the following two embodiments:

UE information corresponding to the multicast address (namely a group of UE which can receive the multicast data and is pre-designated) is stored in the UDR network element, and the PCF network element can authorize the UE to join the multicast group according to the information.
In some embodiments, multicast communications of different QoS may be established for a session by: responding to a protocol data unit PDU session establishment request or PDU session update request of the user terminal, and inquiring multicast group information of one or more multicast groups added by the user terminal in the virtual network group; according to the multicast group information of one or more multicast groups added by the user terminal in the virtual network group, setting QoS information corresponding to the corresponding multicast address for the PDU session established or modified by the user terminal, so that the user terminal establishes multicast communication with different QoS in different multicast groups in the virtual network group.

Further, in some embodiments, multicast communication for establishing different QoS for a session of a user terminal within a 5G VN Group may be implemented specifically by: receiving a protocol data unit PDU (protocol data unit) session establishment request or PDU session update request of a user terminal initiated by an SMF (surface Mount function) network element through a PCF (policy control function) network element; inquiring multicast group information of one or more multicast groups added by the user terminal in the virtual network group from the UDR network element through the PCF network element; setting QoS information corresponding to a corresponding multicast address for a PDU session established or modified by a user terminal according to multicast group information of one or more multicast groups added by the user terminal in a virtual network group through a PCF network element, and generating first policy control and charging PCC rule information; and the PCF network element transmits the first policy control and charging PCC rule information to the SMF network element, so that the SMF network element establishes multicast communication with different QoS for different multicast groups in the virtual network group according to the first policy control and charging PCC rule information.
Further, in some embodiments, the multicast communication for establishing a corresponding QoS for a user terminal newly joining a certain multicast Group in the 5G VN Group may be implemented specifically by the following steps: receiving a multicast group joining application request of a user terminal initiated by an SMF network element through a PCF network element of a strategy control function; inquiring the multicast group information of the multicast group which the user terminal applies to join from the UDR network element through the PCF network element; setting corresponding QoS information for a multicast address applied to be added by the user terminal according to the multicast group information of the multicast group applied to be added by the user terminal through the PCF network element, and generating second PCC rule information; and the PCF network element transmits the second PCC rule information to the SMF network element so that the SMF network element establishes multicast communication of corresponding QoS for the multicast group added by the user terminal in the virtual network group.
Taking 5G VN Group as an example, fig. 4 shows a flowchart of a specific implementation of a multicast communication method for a virtual network Group in an embodiment of the present disclosure, as shown in fig. 4, specifically including the following steps:
s402, the AF network element configures multicast group information (including but not limited to, multicast address, qoS information, and UE information).
S404, the NEF network element configures multicast group information (including but not limited to, multicast address, qoS information, and UE information) into the UDR network element.
In specific implementation, the NEF network element may directly configure the multicast Group information into the UDR network element, or may first configure the multicast Group information of the 5G VN Group into the UDM network element, and then configure the multicast Group information of the 5G VN Group into the UDR network element by the UDM network element.
S406, the UE initiates a session establishment request or a session update request or a multicast group joining application request to the SMF network element.
S408, the SMF network element initiates a session establishment request or a session update request or a multicast group joining application request of the UE to the PCF network element.
