Problems solved by technology

When the 5G network is used to replace the bridge to transmit the data flow, because the network management equipment cannot obtain the transmission service capability of the 5G network, when each end station in the TSN sends the data flow through the 5G network, the transmission delay of the 5G network is not considered. Whether it can meet the quality of service (Quality of Service, QoS) requirements of the data flow, which may easily lead to the failure of sending the data flow in TSN

Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0025] In the description of the present invention, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" and "plurality" mean two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0026] Below, introduce inventive concept of the present invention: figure 1 It shows the network topology of the delay-sensitive network TSN commonly used in the industrial I...

Abstract

The invention discloses a communication method and network management equipment, relates to the technical field of communication, and is used for normally transmitting a data stream in a TSN by utilizing a 5G network. The method comprises the steps: receiving a data sending request; acquiring routing information of a target route in the TSN, wherein the target route is used for transmitting a datastream between a source node and a target node through a 5G network; querying a port identifier of a first port and a port identifier of a second port of the 5G network from the routing information of the target route; sending a target time delay request to a session management function SMF device of the 5G network, wherein the target time delay request is used for requesting the SMF device to feed back a target time delay to the network management device, and the target time delay is the transmission time delay of the data stream in a 5G network when the data stream is transmitted from the first port to the second port; receiving a target time delay from the SMF device; if it is determined that the target time delay is less than the first time delay, sending the target data stream by using the target route. The embodiments of the present invention are applied to a TSN comprising a 5G network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method and network management equipment. Background technique [0002] At present, with the rapid development of the fifth generation mobile communication system (5th Generation, 5G), 5G networks have been able to be applied to various industries, including using 5G networks instead of bridges to access delay-sensitive networks commonly used in the industrial Internet. In (Time-Sensitive Networking, TSN), each end station in the TSN can realize the transmission of data streams through the 5G network. [0003] However, in the TSN where the network bridges are managed centrally by the network management device, the network management device is responsible for obtaining the transmission service capability and topology information of the bridge, and distributing the end-to-end path to each end station and the bridge. When the 5G network is used to repla...
