The IPv6 protocol has large address space and address structure, is convenient to realize address aggregation, supports automatic address configuration and host movement, and has better safety and service quality than the IPv4 address protocol. The IPv6 has been already determined to be The development direction of network bearers and service applications, whether The Universal Mobile Telecommunications System (UMTS) of The 3rd Generation Partnership Project (3 GPP) or The CDMA2000 System of 3GPP 2. Especially in the IP Multimedia System (IMS) phase of 3G, the network system will be fully IPv6 based or compatible. IPv6 has become a common basic protocol for the internet and mobile communication networks. The mobile IPv6 enables the Internet and the mobile communication network to be converged, and can provide ubiquitous and 'always-on' connection, which further accelerates the application of the IPv6 technology in 3G networks and mobile terminals.
Since most terminals still only support the IPv4 protocol at present, an important issue to be considered by each large network operator in the process of migrating the network to IPv6 is support and compatibility for IPv4 users.
In summary, the protocol stack types of the network include: IPv4 single stack, IPv6 single stack and IPv4/IPv6 dual stack functions. The dual stack of IPv4/IPv6 is divided into a dual stack supporting single Packet Data Protocol (IPv4v6Packet Data Protocol Context, IPv4v6PDP Context) and a dual stack supporting dual PDP (ParallelIPv4 and IPv 6PDP Contexts).
Different Mobile Terminals (MT) also support the above network protocols. Some mobile terminals only support IPv6 single stack and IPv4 single stack, and some mobile terminals do not support single PDP double stack.

specifically, in this step, the mobile terminal may actively report the network protocol type supported by itself when being powered on, or may send the network protocol type supported by itself to the terminal device in a query response manner after receiving a network protocol type query message sent to the mobile terminal by the terminal device.
Here, a control message of a wireless service type may be preset, and the mobile terminal reads a network protocol type parameter supported by itself, constructs the control message, and reports the network protocol type supported by itself to the terminal device through the control message. The network protocol types comprise IPv4 single stack, IPv6 single stack, double PDP double stack and single PDP double stack.
102, the terminal equipment determines the configuration options of a user interface according to the network protocol type supported by the mobile terminal;

Step 206, the user interface displays the setting of the double APNs, and step 207 is executed;
here, when the analyzed message code is 0x03, it indicates that the network protocol types supported by the mobile terminal are IPv4 single stack, IPv6 single stack, and dual PDP dual stack, and therefore, the user interface displays the dual APN setting.

specifically, in this step, the mobile terminal processes the dialing instruction and fills the processed dialing instruction into a PDP dialing initiation request message specified by 3GPP, and sends the processed dialing instruction to the wireless network, and specifically, the mobile terminal may perform character string analysis on the received dialing instruction to obtain a dialing parameter, such as a dialing protocol type, an APN, and other parameters, and then call a corresponding protocol stack according to the dialing protocol type, and fill the APN into the PDP dialing initiation request message specified by 3 GPP.
Step 213, the wireless network returns a response message or an error code;
step 214, the mobile terminal analyzes the response message or the error code and performs corresponding processing;
here, the mobile terminal parses the response message or the error code, may automatically fallback to reinitiate the dialing when the dialing connection of both IPv4 and IPv6 fails, and when the parsed error code is 52 in the 3GPP protocol, it indicates that one of the dialing connections of IPv4 and IPv6 fails, and then step 215 is executed.
In step 215, the mobile terminal sends a trigger message to the terminal device, and step 211 is executed.
It should be understood that, after the mobile terminal sends the trigger message to the terminal device, the step 211 is specifically executed as follows: after receiving the trigger message, the terminal device performs analysis, issues an IPv4 dialing instruction to the mobile terminal when the failed dial connection is IPv6, issues an IPv4 dialing instruction to the mobile terminal when the failed dial connection is IPv6, and refers to the above step 212 to step 214 in the subsequent processing process, which is not described again.
