Abstract: The method includes that: when a first service has yet not ended before an original lifetime of a first IPv6 address terminates, a first terminal sends an address updating request message for querying about whether or not the first service supports IPv6 address updating to a second terminal; the first terminal receives an address updating response message returned by the second terminal; when a first determination result carried in the address updating response message indicates that the first service supports IPv6 address updating, 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 in the case that the first service has yet not ended when the original lifetime of the first IPv6 address terminates, the first terminal continues executing the first service with the second terminal by virtue of the backup session.
