Claim Text:
1. A method for a communication network comprising: reporting one or more location changes for a plurality of 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) and wherein the reporting is performed using a single message for reporting the one or more location changes for the plurality of users; communicating, for a group comprising the plurality of users, a single per-peer Rx authorization and accounting request (Rx AAR) message from a third network element to a fourth network element to initiate a policy change for the group, wherein the per-peer Rx AAR message comprises an application identifier (ID) for a service definition and the one or more first ULI IEs that define the policy location area; communicating, for the group comprising the plurality of users, a single per-Diameter-peer Gx reauthorization request (Gx RAR) message from the fourth network element to the second network element, wherein the per-Diameter-peer Gx RAR message comprises a policy action for the policy change for the group based on the service definition and the one or more first ULI IEs that define the policy location area, wherein the communicating includes routing the per-peer Rx AAR message and the per-Diameter-peer Gx RAR message using a Proxy Diameter Routing Agent (P-DRA) and wherein the per-peer Rx AAR message and the per-Diameter-peer Gx RAR message each further comprise a correlation key; identifying, at the second network element, one or more users belonging to the group for application of the policy change based, at least in part, on a corresponding ULI IE for each user for which a location change was reported and the one or more first ULI IEs that define the policy location area; and applying the policy change to each of the identified one or more users.
