Long term evolution architecture and mobility
Abstract:
A services node (SN) is provided that functions as a local, premise-based gateway that anchors and aggregates a group of radio nodes (RNs). Accordingly, the SN absorbs the functionalities of conventional mobility management entities (MMEs), as well as serving and packet data network gateways, where the SN appears as a single virtual eNB to a macrocellular core network. As a result, complexity associated with aggregating and controlling a large number of RNs (performed by the SN) is hidden from the core network. Additionally, micro-mobility between individual RNs controlled by an SN is completely handled at a local enterprise gateway level, thus significantly reducing mobility-related signaling from impacting an MME pool in the code network. Moreover local data offloading is made possible via the SN.
