3g is IPv6 's 3G.

People often get confused when they understand the IPv6 in the 3GPP/3GPP2 system, which is caused by the IPv6 at two different levels. First is the data load level, where the user data flow through the operator PLMN from MS to PDN. The other is the transport load level, which is two different logical levels from the data load level. Generally speaking, IPV6 will appear in the four areas of the 3GPP/3GPP2 standard. 2 at the user data load level, 2 at the transport load level. One thing needs to
