In the first part, the architecture and background of the communication system of the disclosed technical solution are presented below.

For example, referring to fig. 1, fig. 1 is a schematic diagram of a architecture of a TSN communication system according to an embodiment of the present application. The TSN communication system includes TSN and 5G systems.

The 5G system comprises 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 (Radio Access Network, RAN)) device and the second network device may be a core network element that may include UPF responsible for handling user packets (e.g. forwarding, charging, lawful interception, etc.), access and mobility management functions (ACCESS AND Mobility Management Function, AMF) responsible for mobility management and connected to the terminal device and RAN, session management functions (Session Management Function, SMF) responsible for session management and connected to the AMF and UPF, policy control functions (Policy Control Function, PCF) responsible for policy control and connected to the SMF, unified data management (Unified DATA MANAGEMENT, UDM) for Unified management of traffic data, and AF for providing traffic data.

The TSN may include an End Station (ES) and a centralized network controller (Centralized Network Controller, CNC) for unified management of traffic of the entire TSN communication system. As shown in fig. 1, the terminal device in the 5G system is connected to one or more TSN End Stations (ES) in a TSN Data Network (DN) outside the 5G system through a device-side TSN converter (DEVICE SIDE TSN Translator, DS-TT). The UPF is connected to one or more ES in the TSN DN via a network TSN converter (Net Work TSN Translator, NW-TT). Wherein, DS-TT and NW-TT can both provide ports (ports) for data transmission.

It should be understood that embodiments of the present application are not limited to the system architecture shown in fig. 1. For example, more or fewer network elements or devices may be included in a communication system to which the information processing method of the embodiments of the present application may be applied. The device or network element in fig. 1 may be hardware, or may be functionally divided software, or a combination of both. The devices or network elements in fig. 1 may communicate with each other via other devices or network elements.

Currently, each Time Sensitive Communication (TSC) service of a TSN Communication system requires that a DS-TT and an NW-TT each provide a port to participate in data transmission of the TSC service. Before the TSC service is executed, two ports participating in data transmission (i.e., a port provided by the DS-TT and a port provided by the NW-TT) must be precisely time-synchronized with a clock of the 5G system, and the TSC service performs data communication strictly according to a designated time on the basis of the synchronization completion, and this time is referred to as 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 5G enabled TSN clock synchronization according to an embodiment of the present application. When the TSN end station is connected to the UPF, a PDU session is established between the terminal device UE1 and the gNB and the core network element, the TSN master clock transmits a high precision clock synchronization protocol (generic Precision Time Protocol, gPTP) to the UE1 with a delay t_1, the clock information is set to t_gm, after the UE1 arrives at gPTP, the arrival time t_i is recorded gPTP by using a 5G internal clock, after that, a gPTP message is transmitted to the gNB via an uplink air interface, the gNB transparently transmits gPTP to the UPF, after the UPF receives a gPTP message, the message is transmitted to the TSN end station with a delay t_2, and the time when the TSN end station leaves the 5G system is t_e by using the 5G internal clock record gPTP, so that 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 connects to the terminal device, a PDU session is established between the terminal device UE1 and the gNB and the core network element, the TSN master clock transmits gPTP to the UE1 after a delay t_1, the clock information is set to t_gm, the UE1 records gPTP arrival time t_i with a 5G internal clock after gPTP arrives, then transmits gPTP message to the gNB through an uplink air interface, the gNB transmits gPTP to the UE2, the UE2 receives gPTP message and transmits to the TSN end station after a delay t_2, and the time leaving the 5G system with a 5G internal clock record gPTP is t_e, so that the clock of the TSN end station is updated to t_gm+t_1+t_2+t_e-t_i. Thus, when multiple terminal devices are connected to the same TSN master clock, multiple terminal devices may initiate PDU session establishment requests to the network device to provide clock synchronization services, where one terminal device provides synchronization services for the TSN master clock. However, according to the existing protocol, the network device cannot distinguish whether the plurality of terminal devices are connected to the same TSN master clock, and after the terminal device that currently provides the synchronization service for the TSN master clock leaves the network, the network device cannot find a suitable terminal device to continue providing the synchronization service for the TSN master clock.

The application provides an information processing method and device, wherein first network equipment acquires a first message, the first message comprises at least one of a clock sensitive network TSN master clock number and a downlink reference signal measurement result, which are connected by terminal equipment, and the first network equipment sends a second message to target terminal equipment, wherein the second message is used for indicating the target terminal equipment to provide clock synchronization service for a TSN terminal station. The first network device is capable of identifying the terminal devices connected to the same TSN master clock based on the TSN master clock number transmitted by at least one terminal device, and may determine the terminal device providing the TSN master clock with the clock synchronization service based on the first message.

In the second part, the protection scope of the claims disclosed in the embodiments of the present application is described as follows.

Referring to fig. 3, fig. 3 is a flowchart of an information processing method according to an embodiment of the present application, where the method can be applied to the communication system shown in fig. 1, and as shown in fig. 3, the method includes the following steps:

RRC signaling may include, but is not limited to, any of RRC RELEASE messages, RRC connection reconfiguration messages, RRC connection reestablishment messages, RRC connection setup messages, RRC connection resume messages, or other RRC messages.

Further, the downlink reference signal measurement result may be a downlink reference signal measurement result obtained by the terminal device based on downlink reference information measurement sent by the network device corresponding to the current serving cell or the network device corresponding to the neighboring cell. The downlink reference signal may be a synchronization signal block (Synchronization Signal Block, SSB) and/or a channel state Information reference signal (CHANNEL STATE Information REFERENCE SIGNALS, CSI-RS) broadcast by the network device, and the downlink reference signal measurement may include at least one of a cell reference signal received Power (REFERENCE SIGNAL RECEIVED Power, RSRP), a cell reference signal received Quality (REFERENCE SIGNAL RECEIVED Quality, RSRQ), a cell signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), a cell received signal strength indication (Received Signal Strength Indicator,RSSI)、SSB RSRP、SSB RSRQ、SSB SINR、SSB RSSI、CSI-RS RSRP、CSI-RS RSPQ、CSI-RS SINR, and a CSI-RS RSSI.

The first message is used for determining a target terminal device for providing clock synchronization service for the TSN master clock, and the at least one terminal device comprises the target terminal device.

When a plurality of terminal devices are connected to the same TSN master clock, one of the terminal devices provides clock synchronization service for the TSN master clock. When the clock synchronization service is provided for the TSN master clock off-line or when there is a terminal device to access the network, the plurality of terminal devices may send a first message to the first network device to assist the first network device or the second network device in selecting an appropriate terminal device to provide the clock synchronization service for the TSN master clock.

S320, the first network device acquires the first message.

In one possible embodiment, the first network device determines the target terminal device based on the first message.

In the embodiment of the application, in the coverage area of the first network device, the first network device may be connected to at least one terminal device, where the at least one terminal device may be connected to the same TSN master clock or may be connected to different TSN master clocks. Thus, the first network device may obtain a first message of at least one terminal device, distinguish whether the at least one terminal device is connected to the same TSN master clock according to the first message, and select, from among the at least one terminal device connected to the same TSN master clock, a terminal device with a best downlink reference signal measurement result, or one of a plurality of terminal devices with a downlink reference signal measurement result higher by Yu Mou by a given threshold as a target terminal device, to provide a clock synchronization service for the TSN master clock when the first message includes the downlink reference signal measurement result.

Specifically, the first network device distinguishes the terminal device connected to the same TSN master clock from at least one terminal device according to the terminal device connection TSN master clock number, and then uses the terminal device with the best corresponding wireless signal quality in the downlink reference signal measurement result of the terminal device connected to the same TSN master clock, or one of the terminal devices with the downlink reference signal measurement result higher Yu Mou given threshold as the terminal device for providing clock synchronization service for the TSN master clock. For example, the first message sent by the terminal device 1 includes the number 0 of the connected TSN master clock and the current serving cell CSI-RS RSRP measurement result-85 dBm, and the first message sent by the terminal device 2 includes the number 0 of the connected TSN master clock and the current serving cell CSI-RS RSRP measurement result-70 dBm, and since the CSI-RS RSRP measurement result of the terminal device 2 is greater than the CSI-RS RSRP measurement result of the terminal device 1, the first network device selects the terminal device 2 as the terminal device that provides the clock synchronization service for the TSN master clock.

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

Specifically, the first network device sends different uplink reference signal configuration information to at least one terminal device, and after each terminal device receives the corresponding uplink reference signal configuration information, each terminal device sends an uplink reference signal to the first network device, where the uplink reference signal configuration information may include an uplink reference signal resource set, an uplink reference signal sending period, used spatial relationship information, and the like. Further, the uplink reference signal configuration information may further include transmission activation information of the uplink reference signal. In some examples, the transmission activation information of the uplink reference signal may also be transmitted to the terminal device through separate signaling. After receiving the uplink reference signal configuration information, the terminal device may periodically send an uplink reference signal to the first network device according to the uplink reference signal sending period. The first network equipment receiving the uplink reference signals respectively measures the uplink reference signals sent by the terminal equipment to obtain uplink reference signal measurement results of the terminal equipment and the first network equipment.

The uplink reference signal may be a channel Sounding reference signal (Sounding REFERENCE SIGNAL, SRS). The uplink reference signal measurement result may include at least one of RSRP, RSRQ, SINR, RSSI, SRS RSRP, SRS RSRQ, SRS SINR, SRS RSSI.

In some examples, when the first message includes only the TSN master clock number to which the terminal device is connected, the terminal device may further send the measured downlink reference signal measurement result to the first network device, so as to assist the first network device in determining the target terminal device.

In other examples, when the first message only includes the TSN master clock number to which the terminal device is connected, and after the terminal device receives the uplink reference signal configuration information sent by the first network device, the terminal device may uplink reference signals to the first network device, and the first network device that receives the uplink reference signals respectively measures the uplink reference signal configuration information, so as to obtain uplink reference signal measurement results of each terminal device and the first network device.

In other examples, when the first message only includes the TSN master clock number to which the terminal device is connected, the terminal device may send a downlink reference signal measurement result to the first network device, and after the terminal device receives the uplink reference signal configuration information sent by the first network device, the terminal device may also send an uplink reference signal to the first network device, where the first network device that receives the uplink reference signal performs measurement respectively, so as to obtain uplink reference signal measurement results of each terminal device and the first network device.

In one possible embodiment, the first network device determining the target terminal device according to the first message includes that the first network device determines the target terminal device based on the TSN master clock number and a first measurement result, wherein the first measurement result includes at least one of a measurement result based on an uplink reference signal and a measurement result based on measuring the uplink reference signal.

The first message includes a TSN master clock number connected with the terminal device and a downlink reference signal measurement result, or the first message includes only the TSN master clock number connected with the terminal device, and when the terminal device sends the downlink reference signal measurement result to the first network device, the first network device can determine the target terminal device according to the TSN master clock number and the downlink reference signal measurement result.

Specifically, the first network device distinguishes the terminal device connected to the same TSN master clock from at least one terminal device according to the terminal device connection TSN master clock number, and then uses the terminal device with the best corresponding wireless signal quality in the downlink reference signal measurement result of the terminal device connected to the same TSN master clock, or one of the plurality of terminal devices with the downlink reference signal measurement result being Yu Mou higher than the given threshold as the target terminal device. For example, the first message sent by the terminal device 1 includes the number 0 of the connected TSN master clock, the downlink reference signal measurement result carries the current serving cell CSI-RS RSRP measurement result-85 dBm, the first message sent by the terminal device 2 includes the number 0 of the connected TSN master clock, the downlink reference signal measurement result carries the current serving cell CSI-RS RSRP measurement result-70 dBm, and since the CSI-RS RSRP measurement result of the terminal device 2 is greater than the CSI-RS RSRP measurement result of the terminal device 1, the first network device selects the terminal device 2 as the terminal device for providing the clock synchronization service for the TSN master clock.

The first message only includes the TSN master clock number connected to the terminal device, and when the first network device receives the uplink reference signal, the first network device may measure the received uplink reference signal to obtain an uplink reference signal measurement result. And the first network equipment determines the target terminal equipment according to the TSN master clock number and the uplink reference signal measurement result.

Specifically, the first network device distinguishes the terminal device connected to the same TSN master clock from at least one terminal device according to the terminal device connection TSN master clock number, and then uses one of the terminal devices with best corresponding wireless signal quality in the uplink reference signal measurement results of the terminal devices connected to the same TSN master clock, or one of the terminal devices with downlink reference signal measurement results higher by Yu Mou given threshold as the target terminal device. For example, the first message sent by the terminal device 1 includes the number 0 of the connected TSN master clock, and the first message sent by the terminal device 2 includes the number 0 of the connected TSN master clock. The first network device configures different SRS configuration information for the terminal device 1 and the terminal device 2 respectively, and after the terminal device 1 and the terminal device 2 receive the SRS configuration information, the terminal device 1 and the terminal device 2 send SRS to the first network device respectively. The first network device respectively measures the SRS received from the terminal device 1 and the terminal device 2, and obtains an SRS RSRP measurement result of-85 dBm of the terminal device 1 and an SRS RSRP measurement result of-70 dBm of the terminal device 2. Since the CSI-RS RSRP measurement result of the terminal device 2 is larger than the CSI-RS RSRP measurement result of the terminal device 1, the first network device selects the terminal device 2 as the terminal device that provides the clock synchronization service for the TSN master clock.

The first message comprises a TSN main clock number connected with the terminal equipment and a downlink reference signal measurement result, and the first network equipment receives an uplink reference signal, or the first message only comprises the TSN main clock number connected with the terminal equipment, and when the first network equipment receives the downlink reference signal measurement result and the uplink reference signal, the first network equipment measures the received uplink reference signal to obtain an uplink reference signal measurement result. And the first network equipment determines the target terminal equipment according to the TSN master clock number, the uplink reference signal measurement result and the downlink reference signal measurement result.

Specifically, the first network device distinguishes terminal devices connected to the same TSN master clock from at least one terminal device according to the terminal device connection TSN master clock number, and then uses one of the terminal devices with best corresponding wireless signal quality or a plurality of terminal devices with downlink reference signal measurement results higher by Yu Mou given threshold from the uplink reference signal measurement results and the downlink reference signal measurement results of the terminal devices connected to the same TSN master clock as the target terminal device. For example, the first message sent by the terminal device 1 includes the number 0 of the connected TSN master clock, and the first message sent by the terminal device 2 includes the number 0 of the connected TSN master clock. The first network device configures different SRS configuration information for the terminal device 1 and the terminal device 2 respectively, and after the terminal device 1 and the terminal device 2 receive the SRS configuration information, the downlink reference signal measurement result and the SRS are respectively sent to the first network device, wherein the current serving cell CSI-RS RSRP measurement result of the terminal device 1 is-85 dBm, and the current serving cell CSI-RS RSRP measurement result of the terminal device 2 is-70 dBm. The first network device measures the SRS received from the terminal device 1 and the terminal device 2 respectively, and obtains the SRS RSRP measurement result of the terminal device 1 as-80 dBm and the SRS RSRP measurement result of the terminal device 2 as-75 dBm. Since the CSI-RS RSRP measurement result of the terminal device 2 is greater than the CSI-RS RSRP measurement result of the terminal device 1, the SRS RSRP measurement result of the terminal device 2 is greater than the SRS RSRP measurement result of the terminal device 1, and the first network device selects the terminal device 2 as the terminal device that provides the clock synchronization service for the TSN master clock.

S330, the first network device sends a second message to the terminal device, wherein the second message is used for indicating the target terminal device to provide clock synchronization service for the TSN terminal station.

The second message is configured to instruct the target terminal device to provide a clock synchronization service for the TSN end station, and includes:

and indicating the target terminal equipment to request to establish a protocol data unit PDU session with the TSN end station and/or 5G network element on the path.

In the embodiment of the present application, when the TSN end station is connected to the terminal device, after determining the target terminal device based on the uplink reference signal measurement results and/or the downlink reference signal measurement results of a plurality of terminals connected to the same TSN master clock, the first network device may send a second message to the target terminal device, where the second message may include a terminal identifier of the target terminal device, a TSN master clock number connected to the target terminal device, and a device trigger request, so as to instruct or allow an application of the target terminal device to initiate a PDU session establishment request related to the TSN master clock synchronization service to the TSN end station and/or a 5G network element on a path, and establish a corresponding PDU session, so that the target terminal device provides the TSN master clock with the clock synchronization service.

S340, the terminal device receives the second message from the first network device.
