Evolved Packet Core
Mitel’s Virtualized Evolved Packet Core (EPC) is a software-based, carrier grade solution that can be deployed on cloud-based infrastructures using Network Functions Virtualization (NFV) to rapidly scale capacity and adapt to new deployment models.
The EPC is specifically designed to optimize the deployment of data and voice services for mobile operators transforming their networks to 4G LTE. Mitel’s EPC solution provides a full suite of standards-defined wireless functions (SGW, PGW and MME) on a virtualized software platform that provides mobile operators the flexibility and cost efficiencies needed to cope with burgeoning growth in mobile data traffic.
Mitel’s Packet Data Network Gateway (PGW) is 3GPP compliant Evolved Packet Core (EPC) network element, which anchors network mobility while functioning as the termination point of the packet data network interface towards internal and external Packet Data Networks (PDNs).
As operators launch Voice over LTE (VoLTE) and Rich Communication Services (RCS) on LTE and address network capacity, coverage and increased M2M device interaction, the signaling load on the core network will increase significantly as driven by key service enablers such as device tracking, paging, dedicated bearer activation, etc.
Mitel’s Serving Gateway (SGW) is 3GPP compliant Evolved Packet Core (EPC) network element, which manages user-plane mobility while functioning as the termination point of the packet data network interface towards EUTRAN.
Mitel’s evolved Packet Data Gateway (ePDG) is a 3GPP compliant solution for enabling secure connection between devices and the mobile operator’s Evolved Packet Core (EPC) over an untrusted non-3GPP access network.
