Abstract: Systems and methods are disclosed for a local evolved packet core (EPC) that interoperates with an eNodeB and a remote EPC. If it is determined that it is possible or likely that the eNodeBs may lose the connection to the remote EPC, or if a connection has been lost, the local EPC may serve as a transparent proxy between the eNodeBs and the remote EPC, identify active sessions and transparently proxy those sessions, destroy or de-allocate unneeded sessions or bearers, and download and synchronize application data and authentication credentials, such as HSS or AAA data, to provide authentication to mobile devices once offline. The use of the local EPC and/or the remote EPC may be toggled, or switched, preemptively or reactively, based on various network conditions. The remote EPC may be disconnected proactively when the local EPC determines that there is no connectivity.

Abstract: A gateway situated between the RAN and the core network may provide 2G/3G/4G/Wi-Fi convergence for nodes in a network on a plurality of radio access technologies. In some embodiments, a convergence gateway is described that allows for legacy radio access network functions to be provided by all-IP core network nodes. A multi-RAT gateway provides 2G/3G Iuh to IuPS interworking, IuCS to VoLTE interworking via a VoLTE proxy, IuPS and 4G data local breakout or S1-U interworking, and 2G A/IP and Gb/IP to VoLTE and S1-U/local breakout interworking. The multi-RAT gateway may thereby support all voice calls via VoLTE, and all data over S1 or local breakout, including VoLTE. The multi-RAT gateway may provide self-organizing network (SON) capabilities for all RATs. A multi-RAT base station may provide 2G and 3G front-end interworking to Iuh.

Abstract: Systems and methods for an in-vehicle base station are described. In one embodiment, a method is disclosed, comprising: broadcasting, using the first access radio, the cellular access network at a first power; transmitting the location of the mobile base station to the cellular network; detecting, at the processor, a transition of the mobile base station from a stationary state to a moving state; reducing, at the first access radio, a transmit power of the cellular access network while in the moving state for disabling the cellular access network outside the vehicle; and increasing, at the first access radio, the transmit power of the mobile base station when exiting the moving state.
