摘要： The present invention relates to a method and to an arrangement for synchronising at least one local oscillator (21) with a central time- generating unit (11). The local oscillator (21) serves a so-called element ( 2) included in a network (A), and the time-generating unit (11) is included in a so-called main unit (1) also included in the network (A). The frequency of t he local oscillator (21) can be controlled by periodic and automatic calibratio n. The physical requirements within a part of the network (A) that includes the main unit (1) and all elements (2, 3, 4) concerned, said part being referred to here as a limited network (B), are so well defined that the transmission time of a time stamp from the main unit (1) to an element (2) will be known with a given degree of certainty. The inter-arrival time of the time stamps is used to calibrate the local oscillator (11) together with the known transmission time.

摘要： A method for detecting a timing reference affected by a change in path delay asymmetry in a communications network comprising a master node having a master clock and a plurality of slave nodes each having a respective slave clock is provided. The method comprises: determining that a first timing reference received by a first slave node indicates a time correction to its slave clock greater than a time correction threshold; determining whether one or more other slave nodes have received a timing reference indicating a time correction to their slave clock greater than a time correction threshold; and determining whether the first timing reference is affected by a change in path delay asymmetry based on the determining of whether one or more other slave nodes have received a timing reference indicating a time correction to their slave clock greater than a time correction threshold. Apparatus and a computer program for detecting a timing reference affected by a change in path delay asymmetry in a communications network are also provided.

摘要： 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.
