1. A cellular communications system having an architecture in which Serving Gateway (SGW) user plane functionality is separated from SGW control plane functionality, the cellular communications system comprising:
a Serving Gateway Control plane entity (SGW-C) partitioned into a plurality of virtual SGW-Cs that correspond to a respective plurality of SGW User Plane (SGW-UP) service areas; and
a plurality of SGW-UP pools each comprising one or more SGW User entities (SGW-Us) wherein each SGW-UP pool serves a respective one of the plurality of SGW-UP service areas.
