PGW-C - PDN Gateway Control plane function

The PGW-C controls the functionality performed by the assigned PGW-U when control and user plane separation is in place. When a subscriber establishes an EPS (Evolved Packet System) bearer to a given PDN, the PGW-C selects and controls the point of attachment to that PDN for the life of the EPS bearer (regardless of any mobility procedures). Responsibilities include resource management for bearer resources, bearer binding, subscriber IP address management and mobility support.
