Abstract
A method for transfer between communications systems includes establishing at least one first data connection channel in a first communications system, selecting at least one second data connection channel from the at least one first data connection channel, where the second data connection channel is included in the first data connection channel and is certain to support transfer from the first communications system to a second communications system or is uncertain whether to support transfer from the first communications system to the second communications system, and transferring the second data connection channel to the second communications system when the terminal device has been transferred from the first communications system to the second communications system.
