Claim:
1. A method for a wireless data terminal to support an Internet Protocol Version 4 (IPv4)/Internet Protocol Version 6 (IPv6) dual stack, comprising: mapping, by the wireless data terminal, a Modem port and a Network Driver Interface Specification (NDIS) port at a user terminal; and receiving, by the wireless data terminal, a network connection instruction, initiating a Packet Data Protocol (PDP) context activation request to a network which a user expects to connect, and establishing a network connection according to the mapped port after the network successfully responds to the PDP context activation request; wherein the network connection comprises an IPv4/IPv6 dual stack network connection, and then the establishing the network connection according the mapped port comprises: establishing a data transmission channel from the Modem port mapped at the user terminal to an IPv4 network side port, and establishing a data transmission channel from the NDIS port mapped at the user terminal to an IPv6 network side port when the received instruction is an IPv4/IPv6 dual stack network connection instruction.
