Evolved Packet Core (EPC) is a flat, efficient IP-based core network architecture, supporting the next generation of Full Service Broadband.
The main driving forces for EPC are the rapid adoption of mobile broadband and the requirements of new multimedia services. The migration of voice traffic to the packet switched domain is also an important consideration. These factors call for increased capacity and improved performance in the core network. Combined with LTE access networks, Evolved Packet Core provides a whole new experience for the user with true broadband access virtually anywhere and a rich variety of applications.
The new core network architecture can be implemented by software upgrades only and supports multiple access technologies. This means that earlier investments in GSM, WCDMA and CDMA equipment are protected.
The new architecture also enables a common core network for convergence, which significantly reduces cost of ownership for operators with both fixed and mobile broadband offerings.
In the simplified flat architecture there are only two nodes in the traffic plane, which makes it inherently more efficient. The flat architecture brings higher throughput and reduced delays.
Ericsson has introduced the industry’s most advanced Evolved Packet Core portfolio. It complies with standards and adds the new functionality to existing Ericsson packet core products, through simple software upgrades.
