Abstract

An example method is provided in one example embodiment and may include receiving a request from a user equipment (UE) to access a wireless access network, wherein the UE is currently accessing one or more other wireless networks; determining by a Policy and Charging Rules Function (PCRF) whether a subscriber associated with the UE is authorized to access the wireless access network based, at least in part, on a profile for the subscriber; and communicating one of a wireless access rejection and a wireless access acceptance to the UE based on the determination. In some instances, the determining can include recovering the profile for the subscriber associated with the UE from a Subscriber Profile Repository (SPR) using an International Mobile Subscriber Identity (IMSI) for the subscriber.
