Claim:
1. A method for rapidly establishing a dual-stack wireless connection, comprising: sending, by a wireless terminal device, after being registered onto a wireless network, an IPv4v6 single packet data protocol (PDP) activation requests, and waiting for a result returned by the network; if a result that the IPv4v6 single-PDP activation is performed successfully is returned by the network, sending, by the wireless terminal device, an IPv4v6 de-activation request, setting, by the wireless terminal device, the IP type of the network as an IPv4v6 single-PDP dual-stack, and entering a standby state; otherwise, sending, by the wireless terminal device, an IPv4 PDP activation request and an IPv6 PDP activation request; and waiting for a result returned by the network; if a result that both the IPv4 and IPv6 are successfully supported is returned by the network, sending, by the wireless terminal device, an IPv4 de-activation request and an IPv6 de-activation request, setting, by the wireless terminal device, the IP type of the network as an IPv4v6 dual-PDP dual-stack, and entering the standby state; initiating, by the wireless terminal device, after receiving a network connection instruction, a PDP activation request corresponding to the determined IP type supported by the network; and if a result that the PDP activation is performed successfully is returned by the network, establishing a data connection.
