The LTE PCC functions include: PCRF (policy and charging rules function) provides policy control and flow based charging control decisions. PCEF (policy and charging enforcement function) implemented in the serving gateway, this enforces gating and QoS for individual IP flows on the behalf of the PCRF.

The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork.

Virtual Routing and Forwarding (VRF) is a key component of Layer 3 MPLS VPNs. It enables PE routers to appear to be many routers to the customer edge (CE) routers. ... This unique separation of routing tables allows PE routers to store routes and forward packets even if the customers are using identical addressing.
