The access terminal (AT) may close the session to conserve battery power, or because the user has turned it off. The network may order the AT to close the session (to free up its assigned UATI) if there is no activity for an extended time (see Session Close ).
In the session closing state, the test set is in the process of closing the current session.
Close the session by sending the
CALL:SCLose
command, or by selecting
Close Session
. This will close the data connection and the session at one time. See also
Close Session Before Testing New AT
.
You can close the session at any time, and the data connection will be taken to the idle state. However, most ATs will try to immediately re-establish a session (see Session Negotiate State ). You can prevent the AT from re-establishing a session by turning Call Limit Mode on (see Other Considerations for details).
The session closing state is a transitory state (see TAP/ETAP Data Connection Processing Lifecycle and Packet Data Connection Processing States Lifecycle ).
To query the state of the data connection, see Data Connection State Synchronization .
