The TSN includes a switching node (bridge) and a data terminal. The switching node can forward messages through its configured or created forwarding rules. The data terminal can be divided into a sender (talker) and a receiver (listener). In order to achieve end-to-end deterministic transmission, based on the network architecture of the 5G system, the control plane of the TSN adaptation function is added to the application function (AF) network element. ) Network elements and user equipment (User Equipment, UE) increase the user plane of the TSN adaptation function.

In the first part, the communication system architecture and background of the technical solution disclosed in this application are introduced as follows.

Exemplarily, please refer to FIG. 1, which shows a schematic structural diagram of a TSN communication system provided by an embodiment of the present application. The TSN communication system includes TSN and 5G systems.

Among them, the 5G system includes at least one terminal device, a first network device, and a second network device. The first network device may be a 5G Radio Access Network (RAN) device, and the second network device may be a core network element, which may include these network elements: responsible for processing user messages (Such as forwarding, billing, lawful monitoring, etc.) UPF, responsible for mobility management and connected to terminal equipment and RAN access and mobility management function (Access and Mobility Management Function, AMF), responsible for session management and with AMF Session Management Function (SMF) connected to UPF, Policy Control Function (PCF) responsible for policy control and connected to SMF, Unified Data Management (Unified Data) for unified management of business data Management, UDM) and AF used to provide business data.

Among them, TSN may include end station equipment (End Station, ES) and centralized network controller (Centralized Network Controller, CNC), and the CNC is used for unified management of the services of the entire TSN communication system. As shown in Figure 1, the terminal equipment in the 5G system passes through the Device Side TSN Translator (DS-TT) and one or more TSN terminals in the TSN data network (Data Network, DN) outside the 5G system. End Stations (ES) are connected. The UPF is connected to one or more ESs in the TSN DN through a network TSN converter (Net Work TSN Translator, NW-TT). Among them, both DS-TT and NW-TT can provide ports for data transmission.

It should be understood that the embodiment of the present application is not limited to the system architecture shown in FIG. 1. For example, a communication system to which the information processing method of the embodiment of the present application can be applied may include more or fewer network elements or devices. The device or network element in Figure 1 can be hardware, software that is functionally divided, or a combination of the two. The devices or network elements in Figure 1 can communicate with other devices or network elements.

At present, each Time Sensitive Communication (TSC) service of the TSN communication system requires DS-TT and NW-TT to each provide a port to participate in the data transmission of the TSC service. Before executing the TSC service, the two ports involved in data transmission (that is, the port provided by DS-TT and the port provided by NW-TT) must achieve precise time synchronization with the 5G system clock. After completing the synchronization, the TSC service Data communication is carried out in strict accordance with the designated time; this time refers to the time of the TSN domain (TSN Domain). The terminal device needs to perform strict clock synchronization with the network. For example, as shown in FIG. 2, FIG. 2 is a schematic diagram of a 5G-enabled TSN clock synchronization provided by an embodiment of the application. When the TSN end station is connected to the UPF, the terminal device UE1 establishes a PDU session with the gNB and the core network element. The TSN master clock sends the Generic Precision Time Protocol (gPTP) to UE1 after a delay of t_1. The clock information is set to T_gm. After the gPTP arrives, the UE1 uses the 5G internal clock to record the gPTP arrival time T_i, and then sends the gPTP message to the gNB via the uplink air interface. The gNB transparently transmits the gPTP to the UPF. After the UPF receives the gPTP message, it goes through After a delay of t_2, it is sent to the TSN end station, and the 5G internal clock is used to record the time when the gPTP leaves the 5G system as T_e. Therefore, the clock of the TSN end station is updated to T_gm+t_1+t_2+T_e-T_i. When the TSN end station is connected to the terminal device, the terminal device UE1 establishes a PDU session with the gNB and the core network element. The TSN master clock sends gPTP to UE1 after a delay of t_1. The clock information is set to T_gm. After the gPTP arrives, UE1, Use the 5G internal clock to record the gPTP arrival time T_i, and then send the gPTP message to the gNB through the uplink air interface, and the gNB transparently transmits the gPTP message to UE2. After UE2 receives the gPTP message, it is sent to the TSN end station after a delay of t_2, using 5G The internal clock records the time when gPTP leaves the 5G system as T_e. Therefore, the clock of the TSN end station is updated to T_gm+t_1+t_2+T_e-T_i. Therefore, when multiple terminal devices are connected to the same TSN master clock, multiple terminal devices may initiate a PDU session establishment request to the network device to provide clock synchronization services, and one of the terminal devices provides synchronization services for the TSN master clock. However, according to the existing protocol, the network device cannot distinguish whether the multiple terminal devices are connected to the same TSN master clock, and after the terminal device that currently provides synchronization services for the TSN master clock is off the network, the network device cannot find a suitable terminal The device continues to provide synchronization services for the TSN master clock.

In response to the above problems, this application proposes an information processing method and device. A first network device obtains a first message, where the first message includes at least one of the following: the clock-sensitive network TSN master clock number to which the terminal device is connected, and downlink Reference signal measurement result; the first network device sends a second message to the target terminal device, where the second message is used to instruct the target terminal device to provide a clock synchronization service for the TSN end station. The first network device can identify the terminal device connected to the same TSN master clock according to the TSN master clock number sent by at least one terminal device, and can determine the terminal device that provides the clock synchronization service for the TSN master clock based on the first message.

Since the CSI-RS RSRP measurement result of terminal device 2 is greater than the CSI-RS RSRP measurement result of terminal device 1, the first network device selects terminal device 2 as The TSN master clock provides terminal equipment for clock synchronization services.

In a possible embodiment, the method further includes: the terminal device sends an uplink reference signal to the first network device. Correspondingly, the first network device receives the uplink reference signal from at least one terminal device.

Further, the uplink reference signal configuration information may also include uplink reference signal transmission activation information.

As a result of the RSRP measurement, the first network device selects the terminal device 2 as the terminal device that provides the clock synchronization service for the TSN master clock.

Wherein, the first message only includes the TSN master clock number to which the terminal device is connected. When the first network device receives the uplink reference signal, the first network device can measure the received uplink reference signal to obtain the uplink reference signal measurement result.
