The value of TPID, Priority, CFI and VID are sequentially connected in series, i.e., 8100706491005065, wherein each represent VLAN mark
4 bits in label, or directly with TPID, Priority, CFI and VID of the ectonexine VLAN tag of binary representation
Character string 1,000 0,001 0,000 0,000 0,111 0,000 0,110 0,100 1,001 0,001 0,000 0,000 0,101 0000
0110 0101 are used as APN.When the PDN connections distribution IP address that base station is established according to APN, ectonexine VLAN marks are only considered
Priority, CFI, VID of label, it is possible to distribute IP address of the 112.100.80.101 as the PDN connections.Ectonexine
The TPID of VLAN tag：0x8100 and 0x9100 is then preserved in a base station.
By a similar method, multiple double layer VLANs that UE is supported can be directed to, establish different PDN connections respectively, this
The IP address of a little PDN connections is different.
