ABSTRACT:
A method for performing mode-agile communications during a communications session is disclosed. A communications terminal device supporting multiple modes of access is configured to determine when, during a session involving a first mode of access communications, a second mode of access is available and is to be used for subsequent communications for the session. The communications terminal device initiates or controls switchover from one mode of access to another.
