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: 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.

Abstract: 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.

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: 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.

Abstract translation: 用于在移动接入网络内提供数据高速缓存的系统和方法包括与被配置为管理移动接入网络和外部数据网络之间的通信的一个或多个网络节点相关联地部署数据高速缓存。 在内容提供商网络经由移动接入网络从客户端设备接收到数据请求时，内容提供商网络可以确定所请求的数据是否被缓存在管理与内容提供商网络的通信的一个网络节点中。 如果确定了网络节点，则内容提供商网络可以将客户端设备重定向到所确定的网络节点。 客户端设备然后可以从确定的网络节点请求数据。 网络节点可以确定存储所请求数据的缓存服务器，并将客户端设备重定向到缓存服务器。
