A distributed software defined network (SDN) packet core system is configured to support a plurality of radio access technologies. The distributed SDN packet core system can include a cloud-based SDN centralized infrastructure instance and a plurality of local SDN infrastructure instances distributed in proximity to wireless access networks and radio access points thereof. The cloud-based centralized SDN infrastructure instance can be configured to handle network operations that are not latency sensitive. Each local SDN infrastructure instance can include a plurality of computer devices configured to execute a plurality of RAT specific control-plane modules and a plurality of RAT independent packet processing modules for performing latency sensitive network operations.

Distributed software defined wireless packet core system

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.

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.

Internet Connectivity Services provided by mobile wireless stations deployed in drones, balloons, airplanes etc. may be intermittent and in some cases event-driven, such as in response to emergency and natural disasters. In such deployments, end users of wireless devices may not know that Internet connectivity has become available. Even when the wireless device, such as a smartphone, is able to autonomously attach to the network when Internet connectivity becomes available, end users may not realize that their devices have re-connected to the network. The proposed systems and methods relate to providing Internet service availability notification to end users. The proposed systems and methods collect data related to Internet service availability notifications for analytics.

Method and system for overlaying videos in a television include: receiving a plurality of video signals directly from a plurality of video sources by the television; receiving and processing a script by the television, the script includes instructions for placing a first picture from a first video signal of the plurality of video signals in a first position at a first depth value on a display coupled to the television, and instructions for placing a second picture from a second video signal of the plurality of video signals in a second position at a second depth value on the display; and simultaneously displaying the first picture and the second picture on the display by the television in an overlayed manner, the first picture being displayed at the first position and at the first depth value, the second picture being displayed at the second position and at the second depth value.

A system includes a television set for displaying a video for a viewer. The television set connects to a persona television system over a data network and sends a request for a television show for a persona to the persona television system. A 'persona' includes a character representation of a person other than the viewer, an event, or a group. The persona television system selects a television show based on the persona. The persona television system sends to the television set a show description of the television show. The show description includes video source information about video source such that the television set can obtain television show from video source. In this manner, a data network video is automatically selected as a television show based on a persona and provided to the television set, increasing the ease with which the viewer can identify video choices of interest.
