How does policy control and charging works in LTE? Behind every successful LTE connection, theres an EPC doing the heavy lifting of both user data traffic and control signaling. P+S-GW A Virtual Evolved Packet Core (vEPC) is a framework for mobile networks' voice and data processing and switching that is implemented by Network Functions Virtualization (NFV), which virtualizes the functions of an Evolved Packet Core (EPC). IPv6 uses different IP headers for data packets, as an IPv6 address is four times larger than an IPv4 address. Core network equipment can manage the processing and collation of charging the data produced by different network nodes. Operations and Maintenance (O&M) centre or operations support systems to build up and provision the core network nodes. GatewayGPRSSupportNode - Part02 SMS-GMSC U-plane It's a more streamlined version of IPv4 and provides better support for real-time traffic by eliminating the fields that are rarely used or are unnecessary. I have written a dedicated post on SGSN and GGSN, which I would encourage you to read to get a better understanding of the packet-switched part of the 2G/3G core network. 1.
