Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular to a message time processing method based on a 5G TSN network. Background Art

[0002] Time Sensitive Networking (TSN) refers to a set of protocol standards developed by the TSN Task Group in the IEEE802.1 Working Group. This standard defines a time-sensitive mechanism for Ethernet data transmission, adding determinism and reliability to standard Ethernet to ensure that Ethernet can provide a stable and consistent service level for the transmission of critical data.

[0003] 5G (5th Generation Mobile Communication Technology) is a new generation of broadband mobile communication technology with the characteristics of high speed, low latency and large connection. It is the network infrastructure for realizing the interconnection of man, machine and things. It has extremely high application value in factories, smart manufacturing, smart mines, industrial automation, smart transportation, smart grid, telemedicine, smart education, virtual reality and augmented reality. Especially when combined with production control, it can give full play to the technical advantages of 5G's low latency and large connection.

[0004] In the current technical research, the technology of merging 5G and TSN is proposed, which will promote the in-depth integration of 5G and TSN networks, thereby generating greater value. The 5G system is virtualized as a bridge in the TSN system, and the control plane (TSN AF) with TSN adaptation function is added to the application function (AF) network element in the network architecture of the 5G system, the network side TSN converter (NW-TT) with TSN adaptation function is added to the user plane function (UPF) network element, and the device side TSN converter (DS-TT) with TSN adaptation function is added to the user equipment (UE) network element. However, after the 5G system is deployed, when many 5G base station devices are running, the base station network management system uses the TR069 protocol to manage 5G base stations, and there will be a large number of heartbeat messages reported regularly. When the heartbeat messages of a large number of base stations are reported to the network management system at the same time, congestion is likely to occur, which will cause the network management system to crash.

[0005] In order to solve the above problems, the present invention proposes a message time processing method based on 5G TSN network. Summary of the invention

[0043] Embodiment 1:

[0044] See also Figures 1-3 In order to solve the problem that the base station heartbeat messages simultaneously impact the network management system, the present invention provides a message time processing method based on the 5G TSN network, comprising the following steps:

[0045] S1: Use the same clock source for base stations and network management systems to synchronize time; details are as follows:

[0046] The base station and the network management system use a unified clock source for timing and time synchronization. The unified timing clock can use GPS, Beidou or a unified clock source, which can also be located on the 5G core network equipment, such as based on NTP (Network Time Protocol) network timing.

[0047] S2: The network management system unifies the heartbeat message time interval of all base stations ; The details are as follows: For details, please refer to Figure 2 ;

[0048] S2.1: First, the network management system sends a message to all base stations to obtain the time interval for the base stations to report heartbeat messages. The network management system sends a message to all managed base stations 1 to base station n to obtain the time interval for the heartbeat messages of all managed base stations 1 to base station n. The following example uses SOAP (Simple Object Access Protocol) in XML (Extensible Markup Language) format to describe the message that the network management system sends to base station 1 to obtain the heartbeat message time interval:

[0142] Among them, the base station local time reported by base station 1 is 2024-07-11T19:15:01:000.

[0143] S3.3: The network management system collects the Device.Time.CurrentLocalTime values ​​of all base stations through the above steps three times in a row, compares it with the current time CurrentACSTime of the network management system server, and obtains the average value of the transmission delay difference. ,in, Indicates the base station ID of the base station management, starting from 1 to ;

[0144]

[0145] in, Indicates base station The local time of the base station returned for the first time; Indicates that the network management system server receives the base station The first time returns the current time of the base station local network management system server; Indicates base station The local time of the base station returned for the second time; Indicates that the network management system server receives the base station The second time returns the current time of the base station local network management system server; Indicates base station The local time of the base station returned for the third time; Indicates that the network management system server receives the base station The third time returns the current time of the base station local network management system server; For base station The transmission delay to the network management system server is used to compare the time of the three events returned by the base station with the time of the network management server and calculate the average value of the delay.

[0146] For example: i = 1,

[0147] CurrentACSTime i1 =2024-07-11T19:15:01:000,

[0148] CurrentLocalTime i1 =2024-07-11T19:15:00:000;

[0149] CurrentACSTime i2 =2024-07-11T19:15:06:000,

[0158]

[0159]

[0160] The estimated time for the network management system to receive the heartbeat after it is enabled is:

[0161]

[0162] S4.2: Base Station Time to start heartbeat reporting:

[0163]

[0164] Constrain the network management system to receive the actual interval time of the heartbeat message of all base stations The calculation is as follows:

[0165]

[0166] Among them, OffSetTimeMax is the average transmission delay difference The maximum value.

[0167] For example: , indicating that the maximum transmission delay from all base stations to the network management system server is 4s. , indicating that the time interval for each base station to send a heartbeat message is 10s. The number of base stations managed by the network management system is n=1000, then:

[0168]

[0170] The maximum transmission delay from the base station to the network management system server, the heartbeat message time interval and the number of base stations are fully considered.

[0171] When i = 3, if (The transmission delay between base station 3 and the network management system is 2s), then:

[0172]

[0173] That is, the time when base station 3 starts to generate heartbeat messages is 2024-07-11T20:00:04:028.

[0174] S5: The network management system completes all base stations After the value is set, it is sent to all base stations;

[0175] S6: The base station receives the After that, stop sending heartbeat messages and wait After the time is reached, the heartbeat message will be reported to the network management system.
