METHOD AND APPARATUSES FOR PROVIDING POLICY AS A NETWORK SERVICE IN A MOBILE CORE NETWORK

摘要

Aspects describe using a network element to facilitate scalability within a communication network and to provide policy as a network service in a mobile core network. The network element can be scalable and can be a primary policy access gateway for a first geographic region and can be a secondary policy access gateway for at least a second geographic region. The first geographic region and the second geographic region can have portions that overlap. Further, the network element can hide topology of the home network from roaming partners.
