Abstract: Die Erfindung betrifft ein Verfahren zum Vermeiden von Funktionsblockaden intelligenter elektronischer Einheiten IEDs (2,4), die als Teil eines lokalen Netzwerks (1) und über das lokal begrenzte Netzwerk (1) miteinander verbunden sind. wobei das lokal begrenzte Netzwerk (1) weist wenigstens zwei Zeitangabeeinheiten (3) aufweist. Das erfindungsgemäße Verfahren, weist folgende Schritte auf:
(1) Eine der Zeitangabeeinheiten (3a) nimmt als Synchronisationsquelle eine aktive Grandmaster-Rolle ein.
(2) Alle anderen Zeitangabeeinheiten (3b, 3c) verbleiben in ihrem Slave-Zustand und synchronisieren sich mit der Zeitangabeeinheit (3a) in der Grandmaster-Rolle.
(3) Wenn eine der Zeitangabeeinheiten (3b, 3c) im Slave-Zustand in die Rolle der Grandmaster-Zeitangabeeinheit wechselt, wird über eine Vorsynchronisationsmeldung (8) allen IEDs (2, 4) in dem lokalen Netzwerk (1) über das Netzwerk (1) mitgeteilt, ob und gegebenenfalls mit welcher vorherigen Grandmaster-Zeitangabeeinheit (3a) die aktuelle Grandmaster-Zeitangabeeinheit (3c) synchronisiert war.
Auf diese Weise ist eine Blockade der Funktion der IEDs (2, 4), die Datenströme erzeugen oder verarbeiten, deren Abtastwerte synchron mit der vorherigen Grandmaster-Zeitangabeeinheit erfasst wurden, vermieden.

Abstract: Disclosed is a computer-implemented method (600) and a TSN bridge (202) for optimizing performance of an indoor industrial network (100), an indoor industrial network (100) therefor, and a method (600) for predicting network problems in an indoor industrial network (100). The method (600) optimizes the performance of an indoor industrial network (100) by utilizing an AI module (212) in a TSN bridge (202). The AI module (212) receives SINR and Delay information from a sync agent in a mobile router, environmental parameters from sensors, and obstacle data from cameras (136). The AI module (212) identifies potential time accuracy deterioration in device clocks based on the received data. This information is then communicated to a CNC (502) and a CUC (504) for adjustment of data packet size. Finally, a User Plane Function (UPF) sync agent (120) is instructed to send updated time information to the devices for clock adjustments.

Abstract: Embodiments of the present invention disclose a service transmission method and a device and a system for implementing the method. The method includes: recognizing a type of a received client service, encapsulating an OTN service, and generating an OTN signal frame or a lower order ODU; querying a tag forwarding base to acquire forwarding information of the OTN signal frame or the lower order ODU; acquiring tag information, and inserting the tag information into an overhead of the OTN signal frame or the lower order ODU; and forwarding the OTN signal frame according to the forwarding information. The method may further include: receiving the OTN signal frame sent by an upstream node, extracting the tag information from the overhead of the OTN signal frame; querying the tag forwarding base according to the tag information, acquiring the forwarding information of the OTN signal frame; and forwarding the OTN signal frame to a downstream node according to the forwarding information. An OTN technology is adopted in both forwarding and transmission of the service. Therefore, in the embodiments of the present invention, the forwarding and the transmission of the service may be performed in an OTN plane only, thereby reducing hardware modules of an MPLS plane.

Abstract: A method is provided for transmitting in-band signaling information in a wireless broadcasting system that transmits broadcast service data through a plurality of data Physical Layer Pipes (PLPs) constituting a frame. Non-PLP signaling information is included in a data PLP for a particular broadcast service and the data PLP is transmitted through a current frame, when no data PLP for the particular broadcast service is transmitted in at least one frame to be transmitted within a maximum schedulable period NMAX from a time the current frame is transmitted. The non-PLP signaling information indicates that no data PLP for the particular broadcast service is transmitted within the maximum schedulable period.

Abstract: The present invention relates to the field of communications technologies and discloses a method, an apparatus and a system for transmitting SDH/Sonet section overhead bytes, which reduce a burden of an intermediate node of a PTN network in a process of transmitting DCC bytes in the PTN network. In the present invention, a pseudo wire is established between a local end node and a peer end node. The local end node separates target overhead bytes from section overhead bytes of an SDH/Sonet frame, where the target overhead bytes include DCC bytes; packages the target overhead bytes to obtain a dedicated overhead packet; and sends the dedicated overhead packet to the peer end node, where the dedicated overhead packet is transmitted as a service packet of the pseudo wire. The embodiments of the present invention are mainly applied to a process of transmitting an SDH/Sonet service in the PTN network.

Abstract: The method for protecting a type B Passive Optical Network (PON) comprises preparation step for preparing an access control by a protection Optical Line Termination (OLT).
The preparation step comprises the steps of:
sending a ranging enabling message defining a ranging gap by a gap delay and a gap duration, the gap delay being the time to wait upon reception of the signalling ranging enabling message to range one single predetermined Optical Network Unit (ONU1) by the protection Optical Line Termination (OLT1),
sending from the currently working Optical Line Termination (OLT0) to the protection Optical Line Termination (OLT1) signalling messages containing the ranging information of each Optical Network Unit (8,10,12) relative to the currently working Optical Line Termination (OLT0),
ranging the predetermined Optical Network Unit (ONU1) by the protection Optical Line Termination (OLT1) during the ranging gap while keeping the currently working Optical Network Unit (OLT0) and the remaining Optical Network Units (ONU0, ONU2) silent,
determining the ranging information of each Optical Network Unit relative to the protection Optical Network Unit (OLT1) from the ranging information of each Optical Network Unit relative to the currently working Optical Termination (OLT0) and the ranging information of the single predetermined Optical Network Unit (ONU1) relative to the protection Optical Line Termination (OLT1).
