Abstract:
Presented herein is a method that may include obtaining, by a session management node associated with a data session of a user equipment, an indication that an error has occurred at an endpoint of a first tunnel of the data session for the user equipment, the data session having a plurality of flows associated with the first tunnel and a second tunnel; transmitting, to an access and mobility management function (AMF), a request to modify resources for a first plurality of flows associated with the first tunnel; obtaining, from the AMF, a response including an indication of a new tunnel assigned to the first plurality of flows; and transmitting a request to a user plane function (UPF) including an identifier associated with the new tunnel for the first plurality of flows to facilitate transmitting data associated with the first plurality of flows over the new tunnel.
