1. A method in a policy node for handling a User Equipment's, UE's, access to a mobile communications network, wherein the policy node comprises policy information for the UE's access rights to the mobile communications network, the method comprising:
receiving a request message from a mobility node, wherein the request message is a request for access restriction information for the UE;
based on the policy information and obtained subscription information for the UE, determining which geographical areas comprised in the mobile communications network the UE is allowed or denied access to; and
transmitting, to the mobility node, over a direct interface between the policy node and the mobility node, access restriction information comprising geographical areas in the mobile communications network the UE is allowed or denied access to, wherein the geographical areas comprise a list of one or more allowed or denied tracking areas.
