Method and Device for Managing Internet Protocol Version 6 Address, and Terminal

A method for managing an Internet Protocol version 6 (IPv6) address, applied to a second terminal, the method comprising:

• receiving an address updating request message for querying about whether or not a first service supports IPv6 address updating from a first terminal, wherein the first service is a service which is currently executed by the first terminal and the second terminal, the first service has yet not ended before an original lifetime of a first IPv6 address terminates, and the first IPv6 address is an IPv6 address adopted for the first service which is currently executed by the first terminal;
• determining whether or not the first service supports the IPv6 address updating to obtain a first determination result;
• and
• when the first determination result indicates that the first service supports the IPv6 address updating, returning an address updating response message carrying the first determination result to the first terminal so that the first terminal requests to establish a backup session for the first service with the second terminal by virtue of a second IPv6 address, which is pre-stored, and continue executing the first service with the second terminal by virtue of the backup session in the case that the first service has yet not ended when the original lifetime of the first IPv6 address terminates.

A device for managing an Internet Protocol version 6 (IPv6) address, applied to a first terminal, the device comprising:

• a first sending component, arranged to, when a first service has yet not ended before an original lifetime of a first IPv6 address terminates, send an address updating request message for querying about whether or not the first service supports IPv6 address updating to a second terminal, wherein the first service is a service which is currently executed by the first terminal and the second terminal, and the first IPv6 address is an IPv6 address adopted for the first service which is currently executed by the first terminal;
• a first receiving component, arranged to receive an address updating response message returned by the second terminal, the address updating response message carrying a first determination result of a determination of the second terminal about whether or not the first service supports IPv6 address updating;
• a backup session establishment component, arranged to, when the first determination result carried in the address updating response message indicates that the first service supports IPv6 address updating, request to establish a backup session for the first service with the second terminal by virtue of a second IPv6 address, which is pre-stored;
• and
• a processing component, arranged to, in the case that the first service has yet not ended when the original lifetime of the first IPv6 address terminates, continue executing the first service with the second terminal by virtue of the backup session.

• a first determination component, arranged to judge whether or not the first service supports the IPv6 address updating to obtain a first determination result;
• and
• a second sending component, arranged to, when the first determination result indicates that the first service supports the IPv6 address updating, return an address updating response message carrying the first determination result to the first terminal so that the first terminal requests to establish a backup session for the first service with the second terminal by virtue of a second IPv6 address, which is pre-stored, and continue executing the first service with the second terminal by virtue of the backup session in the case that the first service has yet not ended when the original lifetime of the first IPv6 address terminates.
