Abstract: A distributed software defined network (SDN) packet core system includes a plurality of interconnected local mobility domains (LMDs). Each LMD includes a plurality of radio access technology (RAT) specific front-end modules associated with at least one RAT and a mobility manager. Each RAT-specific front-end module is configured to handle intra-RAT and intra-LMD mobility events that involve switching connectivity of client devices between two radio access points coupled to the LMD and associated with a first common RAT that is also associated with that RAT-specific front-end module. The mobility manager is coupled to the front-end modules and is configured to handle intra-RAT and inter-LMD mobility events. The mobility manager can also be configured to handle inter-RAT and intra-LMD mobility events if the SDN packet core system supports more than one RAT.

Abstract: A system and method provide for connectivity to multiple network operators at a given time, and sorting outgoing traffic based on criteria associated with the data and the network operators. Available networks are identified, and a mobile device (380) attaches to a first network (340) for communication through a first application (310), and also attaches to a second network (360) for communication through a second application (312), without requiring detachment from the first network (340). Accordingly, traffic for the first application (310) is steered through the selected first network (340), and traffic for the second application (312) is steered through the second network (360).

Abstract: This disclosure provides systems, methods, and apparatus for handover of communications between a plurality of radio user equipment and an egressing mobile base station to an ingressing mobile base station. The user equipment are terrestrially located within a geographical service zone (GSZ) having an ingress zone and an egress zone. When an egressing mobile base station enters an egress zone, it initiates a handover to a management node associated with the GSZ. The management node communicates with the ingressing mobile base station, which has entered the ingress zone, to accept the handover of the connections from the egressing base station. The handover is carried out without any disruption of user equipment communications. The management node can also communicate with a flight control node to control one or more flight parameters of the ingressing or egressing base station to facilitate smooth handover.

Abstract: Systems and methods for balancing load in a distributed software defined network (SDN) packet core system include a stateless load balancer within a local SDN infrastructure instance of the distributed SDN packet core system receiving a data packet for processing by at least one of a plurality of SDN network function modules of local SDN infrastructure instance. The stateless load balancer can direct the data packet to a stateful load balancer residing on a first computing device, among the plurality of computing devices in the local SDN infrastructure instance. The stateful load balancer can determine a stateful data packet processing task to be applied to the data packet and determine a second computing device in the local SDN infrastructure instance for applying the determined stateful data packet processing task to the data packet. The stateful load balancer can then forward the data packet to the second computing device.

Abstract: Systems and methods for providing data caching within a mobile access network include deploying data cache(s) in association with one or more network nodes configured to manage communications between the mobile access network and external data networks. Upon a content provider network receives a data request from a client device via the mobile access network, the content provider network can determine whether the requested data is cached in one of the network nodes managing communications with the content provider network. If a network node is determined, the content provider network can redirect the client device to the determined network node. The client device can then request the data from the determined network node. The network node can determine a caching server storing the requested data and redirecting the client device to the caching server.
