SYSTEM AND METHOD FOR PROVIDING POLICY CHARGING AND RULES FUNCTION DISCOVERY IN A NETWORK ENVIRONMENT

摘要

A method is provided in one example embodiment and may include establishing a first binding for a first session for a UE, wherein the first binding includes, at least in part, PCEF connectivity information for a PCEF associated with a PGW hosting the first session for the UE, wherein the first binding is established by a first DRA in a first IP domain; receiving a request by second DRA in a second IP domain associated with establishing a second session for the UE; determining a PCRF serving the first session for the UE; and binding the second session for the UE with the first session for the UE. A method is provided in another example embodiment and may include exchanging PCEF connectivity information over a Dr interface between a plurality DRAs and maintaining PCEF connectivity information for one or more peer DRAs to which each DRA is connected.

1. A method comprising:
establishing a first binding for a first session for a user equipment (UE), wherein the first binding includes, at least in part, policy charging and enforcement function (PCEF) connectivity information for a PCEF associated with a packet data network gateway hosting the first session for the UE, wherein the first binding is established by a first DIAMETER routing agent (DRA) serving the packet data network gateway in a first IP domain; receiving a request by second DRA in a second IP domain associated with establishing a second session for the UE, wherein the request includes, at least in part, the PCEF connectivity information; determining a policy charging and rules function (PCRF) serving the first session for the UE based, at least in part, on the PCEF connectivity information; and binding the second session for the UE with the first session for the UE based, at least in part, on the PCEF connectivity information.
