Abstract: Convergence times associated with simulated annealing based (SA-based) optimization in wireless networks can be reduced by introducing an additional local or cell-level evaluation step into the evaluation of global solutions. In particular, new local solutions may be evaluated based on local performance criteria when the new solutions are in a global solution deemed to have satisfied a global performance criteria. New local solutions that satisfy their corresponding local performance criteria remain in the new global solution. New local solutions that do not satisfy their corresponding local performance criteria are replaced with a corresponding current local solution from a current global solution, thereby modifying the new global solution. The resulting modified global solution includes both new local solutions and current local solutions prior to being accepted as the current global solution for the next iteration.

Abstract: Embodiments are provided for calibration, preprocessing, and segmentation for user localization and network traffic density estimation. The embodiments include sending, from a network component, a request to a plurality of user equipment (UEs) to participate in reporting localization data. Reports for localization data including no-lock reports are received from at least some of the UEs. The no-lock reports indicate indoor UEs among the UEs. The network preprocesses the localization data by eliminating, from the localization data, data that increases the total noise to signal ratio. The localization data is then processed using a model that distinguishes between different buildings. This includes associating, according to a radio map, radio characteristics in the localization data with corresponding bins in a non-uniform grid of coverage. The non-uniform grid is predetermined to maximize uniqueness between the radio characteristics.

Abstract: A method comprises playing at a device, over a first time period, a video stream having a bit rate. The method further comprises determining a count of stalls in the playing of the video stream; determining, based on the count of stalls and the bit rate, a score for the video stream; and providing, to a server device, the score.

Abstract: Method and apparatus are provided for localizing wireless devices. In one such arrangement, a method of fingerprinting includes receiving, by a first network element, a plurality of records from a second network element and determining a first segment. A first drive test record of the plurality of records can be assigned to the first segment, and a second segment can be determined, where a first area of the first segment is not equal to a second area of the second segment. A second drive test record of the plurality of records can be assigned to the second segment.
