Problems solved by technology

If you choose IPv4 or IPv6 single stack by mistake, networking failure will occur, which will affect the user's use
If you choose IPv4v6 dual-stack, you may face a complicated fallback process, and the process of connecting to each other will be time-consuming and affect user experience

Embodiment Construction

[0027] Below, refer to the attached Figure 1~2 The method and device for automatically correcting the IP type of the present invention are described in detail.

[0028] Such as figure 1 Shown, the method for automatically correcting IP type of the present invention, comprises the following steps:

[0029] Step 11: The wireless terminal device registers to the wireless network and is ready to establish the first connection;

[0030] Step 12: Set the IP type to IPv4v6 for dual-stack connection;

[0031] Step 13: The wireless terminal device sends an IPv4v6 single PDP dual-stack activation request, and waits for the network to return the result. If the network returns successfully, establish a data connection and record the current network information, including the mobile country code (Mobile Country Code, MCC), or mobile Network code (Mobile Network Code, MNC), or access point service provider name (Access Point Name, APN) information, and record that the IP type supported ...

Abstract

The invention provides a method and a device for automatically correcting an IP type, wherein the method includes the following steps that: A, when a wireless terminal device is registered to a wireless network and is in preparation for establishing a first link, an IP type is set to be IPv4v6 to perform a double-stack connection; B, when the wireless terminal device successfully sends an IPv4v6 single grouped data protocol PDP double-stack activation request, or successfully sends an IPv4PDP activation request, or successfully sends an IPv6PDP activation request, a relevant data connection is established, and current network information and a IP type supported by the current network are recorded. The method and the device in the invention can avoid network-connecting failure caused by a wrong PDP type set by a user, and in accordance with an adaptive type obtained from a first attempt, can establish a fast connection successively.

Description

technical field [0001] The invention relates to the technical field of mobile networks, in particular to a method and device for automatically correcting an IP type. Background technique [0002] The fourth version of IPv4, the Internet Protocol (IP), is the Internet protocol widely deployed at present. However, with the rapid development of the Internet, the shortcomings of IPv4 design are becoming more and more obvious, mainly including the insufficient IPv4 address space and the maintenance of backbone routers. The number of routing table entries is too large, it is not easy to automatically configure and re-address, and it is difficult to solve security problems. Internet Protocol Version 6 (IPv6) is the future replacement protocol for IPv4. IPv6 has the advantages of sufficient address space, high routing efficiency, high security, easy configuration and expansion, and supports mobility. [0003] Currently, a large number of networks are IPv4 networks. With the deploy...
