Title: Enhanced media quality management
Inventor: MANI SENTHIL KUMAR
IPC: H04L29/06
Filed: 2015-03-16
Abstract: Configuration managers in transmitting devices may increase bitrate if suitable network conditions are detected, then decrease bitrate if the network conditions change, which can result in oscillation between bitrates above and below the available bandwidth (dashed line, fig.3a). If oscillation is detected in a certain time period then, for a first time period (t1), the device transmits at a first bitrate (BR5) below the available bandwidth and a second bitrate (BR6) above the available bandwidth. In subsequent time periods (t2, t3), the duration of transmission at the first bitrate is increased with respect to the second bitrate, thus the proportion of time transmitting at the first bitrate is greater for the second oscillation period than for the first oscillation period. Bitrates can be changed by e.g. adapting codec parameters and/or packet size. Applications include media streaming such as VoIP.

IPC: H04W36/00
Filed: 2018-01-12
Abstract: A measurement configuration is transmitted S1 to a UE 3 from a base station 5 and the UE performs measurements of signals transmitted in each of a plurality of neighbour cells. The UE transmits a measurement report with at least one result for at least one neighbour cell to the base station S2. The base station receives the report which contains the at least one result and also contains a global unique cell identifier (GCI), also known as a CGI, for a subset of at least one neighbour cell to which the at least one measurement result relates. Based on the GCI a corresponding neighbour cell is identified and a communication procedure (for instance handover) involving the UE and the identified neighbour cell is triggered. The measurement report may also include a PCI of the at least one neighbour cell. Further aspects of the invention provide the use of a Neighbour Relation Table (NRT) and geographical location associated with the UE.
