Abstract
A method, device, and system for automatically selecting an IPv6 address transmission mode are provided. The method includes a Gateway General Packet Radio Service (GPRS) Support Node (GGSN) device adding an identifier of a currently adopted address allocation mode through configuration, and informing it to a mobile terminal; the mobile terminal device obtaining IPv6 address identifier information issued by the GGSN device after completing Packet Data Protocol (PDP) context activation; the mobile terminal device sending a standard router solicitation (RS) message to the GGSN device; the GGSN device attaching the currently adopted address allocation mode when responding with allocated IPv6 address prefix information to the mobile terminal device; and the mobile terminal device analyzing the current address allocation mode sent by the GGSN device, and determining whether the current address allocation mode is to allocate a unique identifier or a unique prefix, and then executing corresponding processing.
