Services in EPS

While GSM was revolutionizing communications and taking mobile telephony to the masses, the World Wide Web was having a similar effect on the Internet. The tremendous popularity of the Internet and its value to end-users in providing relevant applications and information is driving a demand for mobile Internet. The functionality of the Evolved Packet Core (EPC) enables the mobile network operator to offer a new set of services to the users through its flat architecture and enables products and network deployments to be built for bandwidth-intensive services from the very start. In addition, EPC provides a number of features to the operator in order to support provisioning, monitoring, control and charging of these services. EPC is designed for IP services; this means that, in theory, almost any application relying on IP communication can utilize the IP access service offered by EPC. IP networks higher layer functionality is implemented in client and server applications residing on a terminal and a network server respectively. The role of the radio network and packet core network is to provide IP communication between the two end-points, the two IP hosts.
