1. A method of establishing a data traffic session for a user equipment (UE) on a network, the method comprising:
receiving, by a session management node, from the UE, a request to set up the data traffic session;
establishing the data traffic session with a first packet routing node;
receiving, by the session management node, from a network repository or the first packet routing node, an indication of unavailability of the first packet routing node to handle UE data traffic;
based on at least a status of the first packet routing node changing from available to handle UE data traffic to unavailable to handle UE data traffic, moving the data traffic session to an available first alternate packet routing node;
monitoring a service performance between the first alternate packet routing node and a packet data network (PDN); and
based on at least the service performance between the first alternate packet routing node and the PDN meeting a performance threshold, indicating, by the first alternate packet routing node, to the network repository, the availability or unavailability of the first alternate packet routing node to handle UE data traffic.
