Section: 5.2.1.6 Call connected
Content: Upon receiving an indication that the call has been accepted, the call control entity of the network shall: through connect the traffic channel (including the connection of an interworking function, if required) and send a CONNECT message to its peer entity at the calling mobile station; start timer T313 and enter the "connect indication" state. This message indicates to the call control entity of the calling mobile station that a connection has been established through the network. The call control entity of the mobile station in the "call initiated" state, in the "mobile originating call proceeding" state or in the "call delivered" state, shall, upon receipt of a CONNECT message: - attach the user connection; - return a CONNECT ACKNOWLEDGE message; - stop any locally generated alerting indication (if applied); - clear any H.324 call established to receive multimedia CAT during the alerting phase (if applied) , as specified in subclause 5.3.6.4 - stop timer T303 and T310 (if running); - enter the "active" state. Abnormal cases: On the mobile station side, if timer T303 or T310 expires, the call control entity of the mobile station shall initiate call clearing as described in subclause 5.4. NOTE: The mobile station may have applied an additional internal alerting supervision which causes initiation of call clearing prior to the expiry of T303 or T310. The call control of the network in the "connect indication" state, shall, upon receipt of a CONNECT ACKNOWLEDGE message: - stop timer T313 and enter the "active" state. Abnormal cases: On the network side, if timer T313 elapses before a CONNECT ACKNOWLEDGE message has been received, the network shall perform the clearing procedure as described in subclause 5.4.
