Abstract
Systems and methods relating to a cellular communications system having an architecture in which Serving Gateway (SGW) user plane functionality is separated from SGW control plane functionality are disclosed. In some embodiments, a cellular communications system having an architecture in which SGW user plane functionality is separated from SGW control plane functionality comprises 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. The cellular communications system further comprises 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. In this manner, the coordination problem between Tracking Areas (TAs) and the SGW-UP service areas is avoided.
