1. A method for transmission reliability, comprising:
receiving, from a first network node at a second network node, a message indicating that a first connection between the first network node and a terminal device has failed, wherein the message comprises an indication to initiate a second connection with the terminal device from the second network node; and
establishing, at the second network node, the second connection with the terminal device based on the message, wherein:
the second network node comprises a third connection to the terminal device established before the first connection failed;
the first connection carries data transmitted in the third connection before the first connection failed; and
the second connection carries data transmitted in the third connection after the first connection failed.
