Methods for estimating Subscriber quality of experience (QOE) for mobile users accessing networks for different services from observed data in control and user planes in mobile wireless networks and then summarizing inferences per user, per service, per sector, group of sectors and other aggregate points, and exporting this information for reducing user churn, network planning and network tuning, application adaptation to improve QOE are disclosed. Methods for improving subscriber QOE metrics for certain applications, services and web-sites for improved monetization methods are also presented. The methods facilitate quantifying network goodness from the user application point of view, and exporting triggers to other network elements, such as SON Server, OSS and PCRF, when QOE anomalies are detected. Additionally, this exported information could also trigger content adaptation, delivery optimizations and other actions. Finally, client, server and intermediary enhancements to improve QOE of certain applications in delay/capacity varying networks are presented.

System and methods for estimation and improvement of user, service and network QOE metrics

Control Plane and User plane packet data are collected within the Radio Access Network using a plurality of network devices. Consolidation and summarization of this information is then performed to present a unified picture of RAN through abstract APIs to management and analytics applications. The invention identifies methods of retaining the collected network data, such as control and application protocol headers at the collection points, and consolidation and exporting this network data to management/reporting/analytics application using application driven rules for consolidation and summarization. Real-time statistical analysis tools, which may be used to predict failure and degradation trends and proactively control the underlying causes, are also disclosed.

Distributed RAN information collection, consolidation and RAN-analytics

Methods for steering the access technology selection by a mobile device in an overlay Small-Cell and Macro Network, such as UMTS, LTE, CDMA, or WIFI are disclosed. This selection determination is based on the observed, real-time correlated and estimated network congestion, content-awareness, application/service expectations, and other criteria. Methods and procedures to influence network selection or control currently selected networks by propagating real-time correlated and consolidated information on a plurality of Radio Access Technologies to Access Points, or modifying the list of alternative Radio Access Technologies available at a location using standards defined mechanisms and parameters are identified. Additionally, steering content access and delivery through alternative access technologies, based on anticipated network usage by user's service activation, and the knowledge of the type, state and resource usage of a plurality of access networks when a mobile device connects to multiple access technologies through in-band or out-of-band mechanisms is identified.

Content and RAN aware network selection in multiple wireless access and small-cell overlay wireless access networks

The present invention identifies methods and procedures for correlating control plane and user plane data, consolidating and abstracting the learned and correlated data in a form convenient for minimizing and exporting to other network devices, such as those in the Core Network and the Access Network, or the origin server, CDN devices or client device. These correlation methods may use Control Plane information from a plurality of interfaces in the RAN, and User plane information from other interfaces in the RAN or CN. IF the device is deployed as an inline proxy, this information may be exported using in-band communication, such as HTTP extension headers in HTTP Request or Response packets, or another protocol header, such as the IP or GTP-U header field. Alternatively, this information can be exported out-of-band using a separate protocol between the RAN Transit Network Device (RTND) and the receiving device.

RAN analytics, control and tuning via multi-protocol, multi-domain, and multi-RAT analysis

The current invention is applicable to a RAN-cache or proxy operating in a wireless mobile network that is functioning as a transparent inline device intercepting wireless mobile protocols such as UMTS, LTE, WIMAX, CDMA etc.), or a traffic off-load device connected to multiple interfaces towards the Core/Internet. The current invention identifies methods for pre-fetching content by emulating portions of a mobile client for gaining connectivity through the mobile-core network, or to use session contexts of other mobile clients in a way not to significantly effect charging and billing for the preloaded content. The pre-load decision of what to pre-load and when to pre-load may be locally derived within the RAN-cache/Proxy device, or in-coordination with a locally connected CDN (Content Delivery Network) device. Other embodiments of the current invention include the RAN-cache/Proxy providing interconnectivity from the locally connected CDN device to other CDN devices through the Mobile Core Network (SGSN/GGSN in UMTS, S-GW/P-GW in LTE etc.).

Content pre-fetching and CDN assist methods in a wireless mobile network

A packet scheduling method and apparatus with the knowledge of application behavior, anticipated usage/behavior based on the type of content, and underlying transport conditions during the time of delivery, is disclosed. This type of scheduling is applicable to a content server or a transit network device in wireless (e.g., 3G, WIMAX, LTE, WIFI) or wire-line networks. Methods for identifying or estimating rendering times of multi-media objects, segmenting a large media content, and automatically pausing or delaying delivery are disclosed. The scheduling reduces transit network bandwidth wastage, and facilitates optimal sharing of network resources such as in a wireless network.

Application, usage and radio link aware transport network scheduler

An application mobility-management entity ('AME') in a radio-access network detects movement of a mobile device and routes application data for already-active application streams associated with the mobile device to the device's new location by establishing a connection to a second AME in the radio-access network. The second AME merges forwarded application data from/to the first AME for previously active application streams with the new application streams (e.g., new TCP connections) locally and forwards to/from the mobile device through the radio access network elements.

Session handover in mobile-network content-delivery devices

The current invention defines a device and a method of logically inserting the device between two other network devices, for example, in a 3GPP Radio Access Network. The device transparently monitors and interacts with one or more control protocol layers in the two neighboring devices. The invention defines methods by which the intercepting node selectively passes through or proxies (selectively modifying portions of the protocols content) in such as way that the neighbor nodes are un-aware of the intercepting device. The proxy operation implies that the intercepting node is capable of terminating some protocol elements, injecting some protocol elements, or modifying protocol elements before forwarding them in such a way that the operation is transparent to neighboring nodes. These selective insertion/modifications facilitate identifying signaling connections for specific mobile clients, and enhancing and modifying service features for dataplane accesses for those client devices, while transparently passing other protocol messages.
