An example method includes reporting location changes for one or more users from a first network element to a second network element based on transitions for each of the one or more users in relation to a policy location area, wherein the policy location area is defined by one or more first user location information (ULI) information elements (IEs); communicating a per-peer Rx authorization and accounting request (Rx AAR) message to initiate a policy change, wherein the per-peer Rx AAR message comprises the one or more first ULI IEs; communicating a per-Diameter-peer Gx reauthorization request (Gx RAR) message including the one or more first ULI IEs; identifying one or more users for the policy change based, at least in part, on a corresponding ULI IE for each user and the one or more first ULI IEs; and applying the policy change to each of the identified one or more users.
