Abstract: Various solutions for handling re-attempt indicator with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a reject message without a back-off timer value from a network node. The apparatus may start a back-off timer by using a predetermined timer value. The apparatus may perform a re-attempt procedure according to a re-attempt indicator.

Abstract: Various solutions for handling back-off timer in session management level congestion control with respect to user equipment and network apparatus in mobile communications are described. An apparatus may establish a first connection with a first packet data network (PDN) or packet data protocol (PDP) type. The apparatus may transmit a first request message with a second PDN or PDP type for establishing a second connection. The apparatus may receive a reject message with a reject cause. The apparatus may transmit a second request message for establishing the second connection without initiating a default back-off timer.
