1. A method for implementing multiple PDNs between an indoor unit (IDU) and an outdoor unit (ODU), applied to the ODU, the method comprising:
allocating at least two first Virtual Local Area Network (VLAN) interfaces to a first physical network interface;
establishing packet data network (PDN) data channels which are in one-to-one correspondence with the first VLAN interfaces, wherein the PDN data channels are configured for data interaction with a base station;
acquiring address allocation requests corresponding to the PDN data channels from the IDU; and
allocating first IP addresses corresponding to the PDN data channels to the IDU according to the address allocation requests, such that data messages from the IDU are routed to the corresponding PDN data channels according to the first Internet Protocol (IP) addresses;
wherein the ODU comprises an application processor (AP) and a modem (MODEM), and the first physical network interface is arranged on the AP;
wherein establishing the PDN data channels which are in one-to-one correspondence with the first VLAN interfaces comprises:
enumerating, by the AP, according to the first VLAN interfaces, Wide Area Network (WAN) interfaces which are in one-to-one correspondence with the first VLAN interfaces, and generating, by the MODEM, virtual network interfaces which are in one-to-one correspondence with the WAN interfaces; and
establishing, according to the first VLAN interfaces, the WAN interfaces and the virtual network interfaces, the PDN data channels which are in one-to-one correspondence with the first VLAN interfaces.
