Abstract: The techniques described herein involve analysis of client device Quality of Experience diagnostic files including an operations log or diagnostic files for a client device. The client device Quality of Experience diagnostic files may be generated by a client device and sent to a network node for analysis. The diagnostic files may be analyzed to determine device Key Performance Indicators and a device Quality of Experience, and to determine a root cause of a network problem (such as dropped calls) leading to a diminished Quality of Experience. In some embodiments, the diagnostic files may be aggregated to form a database of aggregated diagnostics, which can be used to further analyze a network to determine the root cause of a network problem. In some embodiments, the aggregated diagnostics may be indexed according to location, time, device type, device problem, or access technology.

Abstract: Techniques and methods for dynamically tuning of content delivery over a communication network are described. In one aspect, a method of dynamically tuning of content delivery over a communication network may involve a user device detecting an event related to a content delivery traffic from an application server to the user device over the communication network. The method may also involve the user device communicating the detected event to the application server.

Abstract: Techniques for calculating quality of user experience (QoE) scores for video streams as played on receiving devices are described herein. Prior to calculating a QoE score, a device receives a video of a display screen of a receiving device captured while the receiving device plays a video stream. The device also receives transmission metrics from at least one device engaged in the transmission of the video stream to the receiving device. The device then calculates the QoE score for that received video based at least in part on a reference video, the transmission metrics, and one or more QoE models. Additionally, prior to receiving the video or the transmission metrics, the device may automate the transmission of the reference video as the video stream from a sending device to the receiving device over at least one network emulator, including providing network impairment settings to the network emulator.

Abstract: The techniques described herein involve analysis of communication data included in trace file(s) of device(s) involved in a communication. These trace file(s) may each include data associated with multiple layers of a communication protocol stack of a respective device or data associated with a single such layer. The techniques may further involve one or more of determination of performance metrics associated with data at a specific layer of a specific device, correlation of the data between layers of a device, or correlation of data across multiple device(s) involved in the communication. The performance metrics or correlated data may then be analyzed based on thresholds or models to determine whether the performance metrics or correlated data exhibits a degraded quality of user experience. Also or instead, graphic or textual representations of the performance metrics or correlated data may be generated.

Abstract: The techniques described herein present opportunities for service providers and/or network providers to optimize the Quality of User Experience (QoE) for data services by determining, using a broader network-based approach, the root cause of problems causing a service degradation. To determine the root cause of the problems, the techniques may collect different trace files from multiple different nodes in the telecommunications network. Each trace file includes a log of trace identifiers for numerous different data packets that have been generated, received, transmitted, relayed, and/or routed via the node in the telecommunications network, and each trace file log entry may be associated with a timestamp. Once collected, the techniques may correlate the different trace files from the multiple different nodes to identify, using a broader network-based analysis, service optimization opportunities.

Abstract: The techniques and systems described herein are directed, in part, to interactions between one or more mobile device applications, mobile device modems (or communication hardware), networks, and other devices. In some embodiments, a device may record a video using a camera. The device may then increase a block size of a first portion of a frame in the video to create a modified video where the first portion includes a larger block size than a second portion of the frame of the modified video. The increased block size may reduce an amount of data used to transmit the modified video to another device using the network communication.

Abstract: The techniques described herein detect which one of multiple different radio states a radio communication unit of a client device is currently operating in. The techniques may also learn one or more transition parameters that, once satisfied or reached, may switch the radio communication unit from one radio state to another radio state. Using the detected radio state and the learned transition parameters, the client device can optimize network communications.

Abstract: Techniques are described for a device to request a new service flow for best effort (BE) category traffic to assign a priority to the new service flow. For example, a Traffic Priority parameter in a media access control (MAC) message can be used to transmit the priority level for a new BE category service flow. The MAC message can be an AAI DSA-REQ message (specified in IEEE 802.16m draft 9 (2010)). Either a base station or a mobile station can request a new service flow using the MAC message.

Abstract: Techniques are described that can be used to communicate congestion information concerning a downlink or uplink. In response to congestion on a link, a device can attempt to receive traffic on another network, scan for another node, or enter sleep mode for a time. In some cases, determination of congestion can be made based on an amount of time a packet is enqueued as well as the number of packets that experience a similar amount of enqueuing delay.

Abstract: Techniques, at a subscriber station, for assigning packets to queues to prioritize real-time content over non-real time content. Packets with the same connection identifier are assigned to different priority queues. Block sequence numbers are assigned to packets after storage of packets to queues based on priority.

Abstract: The present invention relates to a process for the preparation of organic nitrates having at least one nitryloxy and at least one hydroxy group, wherein the at least one hydroxy group may be present in form of an esterified hydroxy residue, the latter being esterified with an acid other than nitric acid.

Abstract: Embodiments of a mobile station and methods for dynamically adapting a grant interval during Voice-over-Internet Protocol (VoIP) communications in a broadband wireless network are generally described herein. The mobile station may detect a voice-state transition and may provide an indication to a base station to change a grant interval based on the detected voice-state transition. The base station dynamically adapts the grant interval based on the indication. Some embodiments utilize an adaptive granting and polling (aGP) service to dynamically adapt the grant interval based on the detected voice-state transition.
