Rapid changes in the communications industry with more number of subscribers increasing exponentially day-by-day has created certain problems for the service providers. With the increasing demand for personalized services by customers while even on the move, say anytime and anywhere, has increased network operator's challenge to manage their subscribers efficiently. ASN Gateway is the technology that comes to service providers’ rescue at this time.
Being a critical component of any Mobile WiMax network, the ASN Gateway function enables service providers to deploy highly scalable mobile broadband networks, and provides an opportunity for delivering advanced features to enable differentiated service offerings. It also aggregates subscriber and control traffic from base stations within an access network. Situated at the heart of the access network, the ASN GW plays an important role in subscriber management, network optimization, and forwarding of all subscriber traffic. Service providers also need the flexibility to enable new services rapidly. These networks sometimes also support PDN Gateway for LTE.
