1. A broadcast method for a virtual network group, applied to a user plane function (UPF), the method comprising:
receiving a broadcast data packet transmitted by a member in the virtual network group, a target address of the broadcast data packet being a broadcast address;
transmitting the broadcast data packet to a target internal broadcast interface in at least two internal broadcast interfaces, the at least two internal broadcast interfaces including a first internal broadcast interface and a second internal broadcast interface; and
transmitting the broadcast data packet to all members or all local members in the virtual network group by using the target internal broadcast interface,
wherein transmitting the broadcast data packet comprises:
in response to determining the broadcast data packet is from a first reference point or a second reference point: transmitting the broadcast data packet to the first internal broadcast interface, and transmitting, by using the first internal broadcast interface, the broadcast data packet to all the members in the virtual network group by using the first reference point, the second reference point, a third reference point, or a fourth reference point respectively corresponding to each member in the virtual network group; and
in response to determining the broadcast data packet is from the third reference point or the fourth reference point: transmitting the broadcast data packet to the second internal broadcast interface, and transmitting, by using the second internal broadcast interface, the broadcast data packet to all the local members of the UPF by using the first reference point or the second reference point respectively corresponding to each local member of the UPF,
wherein the first reference point is between an access network and the UPF, the second reference point is between the UPF and another UPF, the third reference point is between the UPF and a data network, and the fourth reference point is between the UPF and another protocol data unit session anchor point user plane function (PSA UPF).
