1. A method of handling secondary radio access technology (RAT) data usage for a User Equipment (UE), the method being performed by a mobility node, the method comprising:
obtaining, from a network node, an indication of data usage for the UE using the secondary RAT;
obtaining an event trigger from a policy node for forwarding the indication;
responsive to obtaining the event trigger, forwarding the indication towards the policy node;
obtaining a policy decision originating from the policy node, the policy decision being based on the indication of data usage; and
performing an action based on the policy decision,
wherein the policy node comprises a Policy and Charging Rules Function (PCRF),
wherein the mobility node comprises a Mobility Management Entity (MME),
wherein the indication is forwarded towards the policy node,
wherein the policy decision is received from the policy node, via at least one packet gateway, PGW, and
wherein the at least one PGW implements part of the policy decision by throttling traffic or performing access control.
