This application is filed based on the Chinese patent application with the application number 201910364399.4 and the application date on April 30, 2019, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby incorporated into this application by reference.

Technical field

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.

Background technique

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.

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.

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.

The embodiment of the application provides a method for processing time information, which is specifically used for core network equipment to send data packets to a base station (that is, downlink data transmission), and the method includes:

Step 401: The core network determines the sending time information.

Specifically, the core network reads the sending time point Tm of a certain data packet (such as data packet A) obtained by the device through the TSN interpretation function module; here, the Tm specifically refers to the sending time point from the 5G network. Wherein, the determined sending time information may include at least one of the following:

Another range value related to Tm-Tr: from Tm-Ta-Tr-Tdelta4 to Tm-Ta-Tr+Tdelta4, the Tdelta4 represents the fourth offset value.

It should be noted that the time delay Ta of the RAN and the UE may be predetermined, which is specifically described in the method for determining the first time delay by the base station and the method for obtaining TSN clock information as follows.

Step 402: The core network device (such as UPF) sends the sending time information of the data packet A to the base station.

Specifically, after the core network device obtains the sending time information, it sends it to the lower layer. The lower layer is the SDAP or PDCP layer. Taking PDCP as an example, the base station encapsulates the sending time information in the PDCP payload, and gives a specific identifier in the PDCP header. , And send it to the base station; or, directly indicate the sending time information in the PDCP header and send it to the base station.

Here, the SDAP or PDCP layer of the core network device informs the MAC layer of the transmission time information and the corresponding data packet identifier (such as SN number) through internal messages (such as primitives); the MAC layer uses the above information Select the appropriate SPS/CG resource for the packet.

Here, in addition to the priority, the UPF also determines at least one of the scheduling sequence of the downlink data, the multiplexing sequence of the logical information, or the priority according to the foregoing transmission time information.

Step 403: After interpreting the sending time information, the base station selects an appropriate time point according to the sending time information, and sends the data packet A to downstream nodes, such as other UPFs, neighboring base stations, UEs, and so on.

Step 503: The UE sends the time point at which the TSN clock information is sent to the base station.

Step 504: The base station replies to a message (recorded as the second message) after receiving it, and the second message carries the time point when the first message was received (specifically, it can be combined with FIG. 3, where the time point is shown in FIG. T1 in 3).

Step 505: The base station sends a third piece of information to the UE, and the message carries the time point t2 at which the second message was sent.

Step 506: The UE sends a fourth message to the base station. The fourth message includes the round-trip time (t1-t0+t3-t2) calculated by the UE to the base station, and the message also carries the time point T3.

Step 507: The base station uses the UE to send the calculated round-trip transmission delay (t1-t0+t3-t2), and uses T0-Tr to obtain the processing delay of the UE, and determines the synchronization between itself and the TSN network according to the TSN clock information Point in time.

It can be specifically combined with Figure 3. In Figure 3, Tr represents the arrival time of the data packet, specifically the time point when the TSN clock information reaches the UE; t0 represents the first message sent (the first message may be TSN clock information ); t1 represents the time point when the base station receives the first message; t2 represents the time point when the second message is sent; t3 represents the time point when the terminal receives the second message;

Specifically, the sum of the transmission delay and the processing delay determined by the base station is the first delay.
