    Publication number: 20200259896
    Abstract: Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.

  • Technique for Evaluation of a Parameter Adjustment in a Mobile Communications Network
    Publication number: 20150296395
    Abstract: This disclosure describes a technique for evaluating a parameter adjustment in a mobile communications network using a multivariate performance model that models a dependency of a performance metric for the mobile communications network on at least two parameters. A parameter is selected to be adjusted for a first network entity, where at least one second network entity is potentially affected by the parameter adjustment for the first network entity. The multivariate performance model is used to determine a change of the performance metric for the first network entity resulting from the parameter adjustment, and a change of the performance metric for the at least one second network entity resulting from the parameter adjustment for the first network entity. Then, the parameter adjustment is evaluated based on the performance metric changes for the first and second network entities.
