摘要： A system and method for optimizing the efficiency of data sharing among a set of radio nodes in a radio environment is provided. The technique includes identifying a data unit and assigning it a class, identifying a connectivity type, computing a significance factor based on connectivity type and assigned class, mapping the significance factor to a priority factor, and scheduling output of the data unit based on the priority factor. A scheduler algorithm can be used for scheduling output. The class can be assigned based on which nodes of the set of radio nodes possess copies of the data unit at a given time. An arbitration process can be used to determine the priority factor. A significance factor weighting algorithm, based on how many nodes will be receiving the data and on how much a node needs the data, can be used to determine the significance factor.

摘要： Methods and systems used to plan, optimize, and manage LTE femtocell networks describes an analytical framework and algorithms that allow analysis and planning of various femtocell aspects including dynamic adjustment of femtocell power for interference mitigation, and optimization according to user selectable policies. The framework recommends using a hybrid of both distributed control and centralized policy enforcement. An algorithm having two closely related aspects is provided. The first part is an Iterative and Distributed Algorithm (IDA), which is intended to be executed inside the femtocells. The second part of the algorithm is intended to be used as a toolset and is called Analytic Computational Algorithm (ACA), which is intended to be used in a centralized planning and operations center. The ACA provides a set of conditions that are used to check for convergence of the IDA.

摘要： A system and method for self and group location and tracking based on ultra wide band ranging among members of the group is presented. The system comprises an anchored station, a plurality of nodes, each node having at least knowledge of where the node is facing and heading, knowledge of all pair wise distances among all of the plurality of nodes, and ability to exchange information among the nodes and with the anchored station via relays.

摘要： The packet loss ratio for a network is measured using only end-point packet counter or byte counter data received from ingress and egress network elements, or all edge routers attached to edge network elements in a virtual private network (VPN). After preprocessing the packet count data from the end-points, the data signal is put through a low pass filter of one or more tap sizes to remove high frequency variations in the ingress and egress packet count data due to the inability to sample selected data sets simultaneously. After filtering the data may be integrated in order to increase detection of small amounts of data packet loss. In order to determine if measurable loss has been detected the standard deviation of the signal is calculated over a selected set of data points prior to the window in which the packet loss ratio is calculated. If the detected packet loss is greater than a predetermined detectability threshold based on the computed standard deviation for a target threshold rate for a certain filter size then the loss rate is reported.

摘要： A system and method for the implementation of fine-grained quality of service in a mobile telecommunications environment uses an Auto-IP policy Decision Point (PDP) to determine what traffic optimizations actions should be taken in reaction to various network conditions. The Auto-IP uses as inputs information from a G b interface probe to determine the user identification of an IP data flow, information from the radio access network (RAN) network management system (NMS) regarding network congestion. The cell traffic information is passed onto a traffic analysis and processing engine, the Auto-IP PDP which maps the real-time traffic information into an n-dimensional traffic model. An automated policy decision guiding algorithm is executed on the n-dimensional traffic model and selects policy based on the traffic and cell congestion conditions, without human intervention. Additionally, a consistency check is performed to ensure that new policies are consistent with existing policies. The policy decision outcome is forwarded to the Auto-IP Traffic Optimizer that acts on the network at a point in the network (G i ) that is different from where traffic problem occurs in the RAN. The Auto-IP Traffic Optimizer implements the decisions of the Auto-IP-PDP by performing traffic shaping, TCP window clamping or other traffic optimizations procedures on a cell-by-cell basis.

摘要： A system for the prioritization of quality of service (QoS) alerts and the analysis of the impact of such alerts on service uses a service model in which services are broken into one or more service components and sub-components. Creation of a service dependency model, which is driven by different phases of a service, is key to being able to understand how alerts at the lowest level of the network components affect the overall service for which they are but a component. Alerts are assigned a "handle" and a severity level. Rules are defined to be applied to the alerts to create a Component Status Indicator for each component including a handle. As each CSI propagates up towards the top of the service model dependency graph, each CSI gets modified according to predefined rules. A service impact index is created when the CSI is propagated to the top service component. For each service that is impacted, weights (multipler) are defined according to duration of the alert, number of subscribers, number of services, QoS class of the services impacted or other factors defined by user. The weights are used to multiply the SII to obtain the overall impacting index, which is sorted to obtain the priority list. This method can be employed either centrally at a network operations center or in a distributed manner by pre-processing at central offices. Information contained in the handle component of the CSI can be used to perform root cause analysis of the service impacting alerts so as to more efficiently identify and correct problems.
