Summary:Solutions for providing a data traffic session with proxy-call session control function (P-CSCF) restoration include: receiving an indication, by an application server (AS), that a user equipment (UE) is registered with a first proxy node; receiving, at a subscriber information node, from a call session control function (e.g., over an N70 interface), a first message triggering proxy node restoration; based on at least receiving the first message triggering proxy node restoration, transmitting, by the subscriber information node, to a management node, a second message triggering proxy node restoration; receiving an indication, by the AS, that the UE is registered with a second proxy node different than the first proxy node; and based on at least receiving a session initiation message, establishing the data traffic session for the UE with the second proxy node.
