本申请实施例涉及移动通信技术,尤其涉及一种时间信息的处理方法、定时提前的确定方法及相关设备。The embodiments of the present application relate to mobile communication technology, and in particular, to a method for processing time information, a method for determining timing advance, and related equipment.
现有的时间敏感网络(TSN,Time Sensitive Network)通过一条以太网支持实时控制和同步,例如在运动应用和机器人之间。TSN可以同时支持其他在制造业应用中常见的数据通讯,推动信息科技(IT,Information Technology)和操作技术(OT,Operation Technology)之间的融合。随着工业物联网数据导致网络变得越来越拥堵,TSN如何确保数据可以正常通讯进而让工业物联网可以帮助用户是现在关注的问题。尽管很多在工业物联网中由工业传感器和控制系统采集的数据不都是时间敏感的,还有大量关键任务的、时间敏感的数据必须在严格的延迟和可靠性的范围之内传输和共享。诸如用于传输时间安排、延迟规定、预留带宽以及冗余配置的通用时钟,这种对于TSN的要求使得TSN能确保时间同步的精度,从而支持多个数据流的同步。来自于机器视觉、三维(3D,3 Dimensions)扫描以及功效分析的大数据组可能为网络带宽造成负担。现有的TSN会使用更高的带宽选项支持全双工标准以太网,这些选项包括1Gb、10Gb,甚至400Gb版本的IEEE 802.3。它同时也会提供顶级的IT安全规定和互操作性,以及可以成长到大规模系统的扩展性。The existing Time Sensitive Network (TSN, Time Sensitive Network) supports real-time control and synchronization through an Ethernet, for example, between motion applications and robots. TSN can simultaneously support other common data communications in manufacturing applications, and promote the integration of information technology (IT, Information Technology) and operation technology (OT, Operation Technology). As the industrial Internet of Things data causes the network to become more and more congested, how to ensure that the data can be communicated normally so that the Industrial Internet of Things can help users is now a concern. Although many of the data collected by industrial sensors and control systems in the Industrial Internet of Things are not all time-sensitive, there are still a large number of mission-critical, time-sensitive data that must be transmitted and shared within strict limits of delay and reliability. Such as the common clock used for transmission schedule, delay regulation, reserved bandwidth and redundant configuration, this requirement for TSN enables TSN to ensure the accuracy of time synchronization, thereby supporting the synchronization of multiple data streams. Large data sets derived from machine vision, 3D (3 Dimensions) scanning, and efficacy analysis may burden network bandwidth. The existing TSN will use higher bandwidth options to support full-duplex standard Ethernet. These options include 1Gb, 10Gb, and even 400Gb versions of IEEE 802.3. It will also provide top-level IT security regulations and interoperability, as well as scalability that can grow to large-scale systems.
同时,移动通信的无线网络的定时,多是依赖全称是全球导航卫星系统(GNSS,Global Navigation Satellite System)。GNSS泛指所有的卫星导航系统,包括全球的、区域的和增强的,如美国的GPS、中国的北斗卫星导航系统,以及相关的增强系统,如美国的广域增强系统(WAAS,Wide Area Augmentation System)、欧洲的欧洲静地导航重叠系统(EGNOS,European Geostationary Navigation Overlay Service)和日本的多功能运输卫星增强系统(MSAS,(Multi-Functional Satellite Augmentation System)等,还涵盖在建和以后要建设的其他卫星导航系统。At the same time, the timing of the wireless network of mobile communication is mostly dependent on the full name of the Global Navigation Satellite System (GNSS, Global Navigation Satellite System). GNSS generally refers to all satellite navigation systems, including global, regional and enhanced, such as the United States' GPS, China's Beidou satellite navigation system, and related enhancement systems, such as the United States' Wide Area Augmentation (WAAS) System), European Geostationary Navigation Overlay Service in Europe (EGNOS, European Geostationary Navigation Overlay Service) and Japan’s Multi-Functional Satellite Augmentation System (MSAS, (Multi-Functional Satellite Augmentation System), etc.), which also cover the construction and future construction Other satellite navigation systems.
当TSN业务不是通过网线,而是通过5G系统时,TSN网络系统自身有一个时钟,且TSN业务具体比传统5G业务更加需求严格的时延和抖动控制;所以,需要提供一种能够准确确定5G系统内的时延预算的方法,以克服空口的不稳定性,做出高效准确的无线调度决定。When the TSN service passes through the 5G system instead of a network cable, the TSN network system has a clock itself, and the TSN service requires stricter delay and jitter control than traditional 5G services; therefore, it is necessary to provide a method that can accurately determine 5G The delay budget method in the system overcomes the instability of the air interface and makes efficient and accurate wireless scheduling decisions.
