Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The existing time-sensitive network is dedicated to plant equipment (End Station). UE, TT and the network together form a network bridge, which supports the interconnection of devices behind TT. The UE only provides a path for wireless access, shielding the details of wireless access.

A lot of data in the application on the UE is also time-sensitive and has the deterministic feature of periodic transmission. Time-sensitive networks can also be used to support deterministic transmission.

Question 1: In order to be able to support deterministic transmission, it is necessary to let the RAN know the time when the data is ready to be scheduled by the RAN before the data reaches the Radio Access Network (RAN). For downlink data, the data arrives at the RAN. Time delay, for uplink data, is the time that the data can be scheduled by the RAN when the Uu port is ready. Since the data is time-sensitive, the stay time of the data forwarding inside the terminal cannot be ignored. The problem of how to determine the time when the data is ready to be scheduled by the RAN needs to be solved.

Problem 2: The core network (Core Network, CN) needs to determine the maximum scheduling delay for the RAN, and the delay needs to be able to meet the communication requirements between the client and the server of the time-sensitive application. Therefore, the network needs to determine the delay overhead between the terminal and the network for the application and disclose it to the application. In this way, the application can determine how long in advance the data should be sent, so that the deterministic transmission of the data can be guaranteed, and the data can reach the target end on time and point. The time delay between the terminal and the network is constructed, and the staying time of the data forwarding inside the terminal cannot be ignored. The problem of how to determine the delay between the terminal and the network needs to be solved.

Refer to Figure 1, which shows a time-sensitive network. The main communication network element equipment is introduced as follows:

UE: User Equipment, terminal. The terminal may include: a data entity (such as an application client (APP Client) and a chipset (Chip Set)), and the data of the application may be time-sensitive data and have the deterministic feature of periodic transmission.

AMF: Access and Mobility Management Function, access and mobility management function.

UPF: User Plan Function, user plane function.

SMF: Session Management Function, session management function.

AF: Application Function, application function.

PCF: Policy Control Function, policy control function.

NEF: Network Exposure Function, network opening function.

NG-RAN: 5G access network.

NW-TT: Network TSN Translator, a time-sensitive converter on the network side.

App Server: Application server.

A segment of time delay: the internal stay time of the terminal.

Segment B delay: the delay between the terminal and the wireless access network. The time delay between the terminal and the wireless access network can indicate the time required for data to pass through the terminal and the wireless access network.

C segment delay: the delay between the radio access network and UPF and/or NW-TT. The time delay between the radio access network and the UPF and/or NW-TT may indicate the time required for data to pass through the radio access network and the UPF and/or NW-TT.

The Packet Delay Budget (PDB) can be equal to the sum of the B-segment delay and the C-segment delay.

D segment delay: UPF and/or NW-TT delay and the delay between the data entity server. UPF and/or NW-TT delay and data entity server delay can indicate the time required for data to pass UPF and/or NW-TT delay and data entity server

The delay between the application client and the application server is equivalent to the sum of the A-segment delay, the B-segment delay, the C-segment delay and the D-segment delay.

For uplink data, the time when the application client sends the data plus the A-segment delay can be the time when the RAN can schedule the uplink data.

Therefore, by reporting the A-segment delay and/or data arrival time, the internal stay time of the terminal can be determined, thereby supporting that before the data arrives at the RAN, the RAN knows the data arrival time or the time when the data is ready to be scheduled in advance, and reserves resources in advance.

In an optional implementation manner of the present application, the delay between the terminal and the gateway and/or NW-TT is the time required for data to pass through the DS-TT between the terminal and the gateway and/or NW-TT. Therefore, it can also be called the residence time between the terminal and the gateway and/or NW-TT. In an implementation manner, the time delay between the terminal and the gateway and/or NW-TT does not include the internal stay time of the terminal.

The TT includes DS-TT or NW-TT. For example, the application on the terminal directly sends and receives data through the terminal and the network, and does not connect to the terminal through DS-TT, and then connects to the network through the terminal.
