Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a clock propagation method, network equipment, and a first terminal device. Background Art

[0002] Currently, in Time Sensitive Networking (TSN), the TSN master clock source can exist on the network side. The network-side TSN master clock source sends synchronization information (gPTP (general precise time protocol) messages) carrying the TSN system clock to the UPF (User Plane Function). The NW-TT (Network-Side Translator) module in the UPF adds an entry timestamp to the synchronization information carrying the TSN system clock and updates the clock time in the TSN system clock synchronization information based on the link latency from the TSN master clock source to the UPF. The UPF transmits the TSN system clock information to the UE (User Equipment). The DS-TT (Desktop-Side Translator) in the UE receives the TSN clock information and generates a departure timestamp. The difference between the entry time and departure time is used as the residence time of this time synchronization information in the 5G (fifth-generation mobile communication technology) system. The DS-TT in the UE updates the clock time in the TSN system clock synchronization information based on the residence time in the 5G system, thereby completing downlink clock synchronization in the TSN network. Furthermore, the TSN network's master clock source (5G system clock source) can also be placed on the UE side, introducing a new clock propagation method: uplink clock synchronization. In uplink clock synchronization, time information is distributed not only to the UPF (Network-Telemetry Unit) located in the 5G system, but also to the DS-TT located in the UE. Specifically, the TSN master clock source connected to the UE forwards clock information to the NW-TT on the UPF via the gNB (base station), or vice versa. The TSN master clock source connected to the UE forwards clock information to the UPF via the gNB, which then propagates it to the DS-TTs of other UEs.

[0003] Currently, during clock synchronization, network devices are unaware of time-sensitive networks (TSNs). After receiving a clock message, they only transmit it to a single terminal device. If clock information needs to be transmitted to multiple terminals for clock synchronization, multiple clock messages must be received and transmitted to the corresponding terminal devices one by one. This consumes a large amount of transmission resources and results in resource waste. Summary of the Invention

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0051] In an embodiment of the present invention, a clock propagation method, a network device, and a first terminal device are proposed to solve the problem of high resource consumption in the existing clock synchronization process.

[0052] See also Figure 1 , Figure 1 This is a flow chart of a clock propagation method provided by an embodiment of the present invention, which is applied to network equipment, such as Figure 1 As shown, the method includes the following steps:

[0053] Step 101: Receive a clock synchronization information packet sent by a first terminal device connected to a master clock source in a first time-sensitive network.

[0054] Time Sensitive Networking (TSN) is a term used for network devices, such as base stations, access and mobility management functions (AMFs), or user plane functions (UPFs). In a first time-sensitive network, a first terminal device connected to a grand master (GM) can send a clock synchronization packet to the network device. The first terminal device can receive the clock synchronization packet from the grand master and then send it to the network device.

[0055] Step 102: Send a clock synchronization information packet to a plurality of second terminal devices in a first time-sensitive network.

[0056] That is, the multiple second terminal devices and the first terminal device belong to the same TSN, that is, all belong to the first TSN. After receiving the synchronization information packet, the network device can send the clock synchronization information packet to the multiple second terminal devices in the first time-sensitive network, thereby achieving the purpose of sending clock synchronization information packets to multiple second terminal devices. As an example, the multiple second terminal devices are devices in the first time-sensitive network that are connected to a non-master clock source.

[0057] In the clock propagation method of the embodiment of the present application, the network device can sense the clock synchronization information packet sent by the first terminal device connected to the main clock source in the first time-sensitive network, and send the clock synchronization information packet to multiple second terminal devices in the first time-sensitive network. That is, there is no need to receive multiple clock information one by one and propagate them one by one to the corresponding terminal devices. The network device only needs to receive one clock synchronization information packet sent by the first terminal device, and then send the clock synchronization information packet to multiple second terminal devices to achieve clock synchronization of multiple terminal devices. In this way, the consumption of propagation resources can be reduced and propagation resources can be saved.

[0058] In one embodiment, receiving a clock synchronization information packet sent by a first terminal device connected to a master clock source in a first time-sensitive network includes:

[0059] Receive a first scrambled clock synchronization information packet sent by a first terminal device; wherein the first scrambled clock synchronization information packet is an information packet obtained by scrambling the clock synchronization information packet using a first radio network temporary identifier RNTI;

[0060] The first scrambled clock synchronization information packet is descrambled based on the first RNTI to obtain a clock synchronization information packet.

[0061] In this embodiment, in order to improve the security of information transmission, the first terminal device may obtain the first RNTI from the network device in advance. The first terminal device may use the first RNTI to scramble the clock synchronization information packet to obtain the first scrambled clock synchronization information packet, and send the first scrambled clock synchronization information packet to the network device. After the network device receives the first scrambled clock synchronization information packet, it may descramble the first scrambled clock synchronization information packet based on the first RNTI to obtain the clock synchronization information packet, thereby enabling the network device to perceive the clock synchronization information packet sent by the first terminal device connected to the master clock source in the first time-sensitive network.

[0062] As an example, when the first terminal device connected to the master clock source receives the clock synchronization information packet, the first NAS (Non-Access Stratum) layer or other higher layers indicate the clock synchronization information packet to the AS (Access Stratum) layer of the first terminal device, scramble the clock synchronization information packet with the first RNTI (B-RNTI), and send it to the network device. After the network device receives the data packet scrambled with B-RNTI by the first terminal device connected to the master clock source, the network device descrambles the data packet with B-RNTI to obtain the clock synchronization information packet. The network device can scramble the clock synchronization information packet with the second RNTI (A-RNTI) and send it to multiple second terminal devices connected to the non-master clock source belonging to the same TSN domain.

[0063] As an example, the base station serving the terminal device connected to the main clock source can send the time synchronization information packet to the adjacent base station through dedicated information. As an example, the TSN identifier of the non-main clock source supported by the terminal device within the coverage of the adjacent base station is the same as the TSN identifier of the main clock source supported by the terminal device serving the main clock source.

[0064] As an example, a terminal device connected to a non-master clock source belonging to the same TSN network domain uses the A-RNTI in the embodiment of the present application to demodulate the data packet of semi-static scheduling (SPS) or dynamic scheduling (dynamic grant), which contains clock synchronization information, to obtain the clock synchronization information.

[0065] In one embodiment, sending a clock synchronization information packet to a plurality of second terminal devices in a first time-sensitive network includes:

[0066] Scrambling the clock synchronization information packet based on the second RNTI to obtain a second scrambled clock synchronization information packet;

[0067] A second scrambled clock synchronization information packet is sent to a plurality of second terminal devices in the first time-sensitive network.

[0068] In this embodiment, to improve the security of information transmission, after obtaining a clock synchronization information packet, the network device may scramble the clock synchronization information packet using a second RNTI to obtain a second scrambled clock synchronization information packet, and then send the second scrambled clock synchronization information packet to multiple second terminal devices in the first time-sensitive network, thereby achieving clock synchronization for the multiple terminal devices. The second terminal devices may obtain the second RNTI from the network device in advance and use the second RNTI to descramble the second scrambled clock synchronization information packet to obtain the clock synchronization information packet, thereby achieving clock synchronization.

[0069] In one embodiment, receiving a clock synchronization information packet sent by a first terminal device connected to a master clock source in a first time-sensitive network includes:

[0070] Receive a clock synchronization information packet sent by a first terminal device connected to a master clock source in a first time-sensitive network through the allocated data radio bearer DRB and / or logical channel.

[0071] The network device may allocate DRBs and / or logical channels in advance, and the first terminal device may send clock synchronization information packets through the data radio bearer DRBs and / or logical channels allocated by the network device. The allocated data radio bearer DRBs and / or logical channels may be understood as DRBs and / or logical channels associated with the clock synchronization information packets. The network device may receive the clock synchronization information packets sent by the first terminal device connected to the main clock source in the first time-sensitive network through the allocated data radio bearer DRBs and / or logical channels. As an example, the network device may receive a dedicated PDU Session (protocol data unit session) and / or QoS flows (quality of service flows) identifier notified by the core network to allocate DRBs and / or logical channels.

[0072] In one embodiment, receiving a clock synchronization information packet sent by a first terminal device connected to a master clock source in a first time-sensitive network includes:

[0073] A first signaling sent by a first terminal device connected to a master clock source in a first time-sensitive network is received through the established public protocol data unit session PDU Session, where the first signaling includes a clock synchronization information packet.

[0074] In this embodiment, the network device may pre-establish a public PDU Session (a Session is a session), and receive a first signaling message sent by a first terminal device connected to a master clock source in a first time-sensitive network through the established public protocol data unit session (PDU Session). As an example, the network device may establish a public PDU Session for terminal devices belonging to the same TSN network domain, for example, a public PDU Session may be established for terminal devices belonging to a first TSN.

[0075] In one embodiment, sending a clock synchronization information packet to a plurality of second terminal devices in a first time-sensitive network includes:

[0076] A clock synchronization information packet is sent to a plurality of second terminal devices in a first time-sensitive network via a common PDU Session.

[0077] In this embodiment, after the network device receives the first signaling sent by the first terminal device connected to the master clock source in the first time-sensitive network through the public PDU Session, it can send clock synchronization information packets to multiple second terminal devices in the first time-sensitive network through the public PDU Session.

[0078] In one embodiment, before receiving a clock synchronization information packet sent by a first terminal device connected to a master clock source in a first time-sensitive network, the method further includes:

[0079] Receive first messages sent by multiple terminal devices within the coverage of the network device, wherein the multiple terminal devices include a first terminal device and multiple second terminal devices, and the first message of any terminal device includes a first time-sensitive network TSN identification list or a main clock source identification list of the terminal device connected to the main clock source, and / or a second time-sensitive network TSN identification list or a non-main clock source identification list of the terminal device connected to the non-main clock source.

[0080] A network device can cover multiple terminal devices, and the network device can receive first messages sent by multiple terminal devices within its coverage area. The first time-sensitive network TSN identifier list of the terminal device connected to the master clock source can be understood as the TSN corresponding to the TSN identifier in the first time-sensitive network TSN identifier list, and the terminal device is connected to the master clock source. The master clock source identifier list of the terminal device connected to the master clock source can be understood as the identifier list of the master clock source to which the terminal device is connected. The second time-sensitive network TSN identifier list of the terminal device connected to a non-master clock source can be understood as the TSN network corresponding to the TSN identifier in the second time-sensitive network TSN identifier list, and the terminal device is connected to a non-master clock source. The non-master clock source identifier list of the terminal device connected to the non-master clock source can be understood as the identifier list of the non-master clock source to which the terminal device is connected.

[0081] As an example, the first message may be sent via RRC (Radio Resource Control) signaling or a first NAS signaling. The network device may receive the first RRC signaling or the first NAS signaling sent by multiple terminal devices within the coverage of the network device, and the first RRC signaling or the first NAS signaling carries the first message. The multiple terminal devices include the first terminal device, that is, the first terminal device may send the first RRC signaling or the first NAS signaling to the network device, and the first RRC signaling or the first NAS signaling sent by the first terminal device carries the first message of the first terminal device.

[0082] As an example, the first NAS signaling may include but is not limited to a registration request, a service request, a PDU session establishment request, a PDU session modification request, a control plane service request, an uplink first NAS transport message (UL first NAS transport message), etc. If sent through the first RRC signaling, the network device may include a base station, etc. If sent through the first NAS, the network device may include an AMF or a UPF, etc.

[0083] As an example, the clock synchronization information packet can be sent to the network device as data or load (container / payload) in the second NAS signaling container. Optionally, the second NAS can be sent to the network device through the established public PDU Session. As an example, the second NAS signaling may include but is not limited to a registration request, a service request, a PDU session establishment request, a PDU session modification request, a control plane service request, and an uplink NAS transport message. As an example, the network device receives the NAS signaling sent by the first terminal device, parses the NAS, and obtains the data or load, that is, the time synchronization information packet, that is, the network device can perceive that the data is a clock synchronization information packet of the TSN network. The network device can send the clock synchronization information packet to the terminal device connected to the non-master clock source belonging to the same TSN domain through the established public PDU Session. The terminal device connected to the non-master clock source belonging to the same TSN domain as the first terminal device receives the data packet containing the clock synchronization information from the established public PDU Session, thereby obtaining the clock synchronization information.

[0084] As an example, the first message may further include at least one of the following:

[0085] A relationship configuration list between a network slice identification number list (NSSAI list) and a time-sensitive network TSN identification list (e.g., a first time-sensitive network TSN identification list and / or a second time-sensitive network TSN identification list);

[0086] A relationship configuration list between a network slice identification number list and a clock source identification list (e.g., a master clock source identification list and / or a non-master clock source identification list) (e.g., one or more time-sensitive network identification lists to which one or more network slice identification numbers can be applied);

[0087] A list of configurations of the relationship between the Closed Access Group Identifier (CAG ID) and the Time Sensitive Network (TSN) identifier list;

[0088] A configuration list of relationships between closed access group identification numbers and clock source identification lists (e.g., a list of one or more time-sensitive network identification numbers to which one or more closed access identification numbers can be applied);

[0089] The accuracy information of the master clock source corresponding to the master clock source identification list;

[0090] Granularity information of the master clock source corresponding to the master clock source identifier list.

[0091] In one embodiment, after receiving first messages sent by multiple terminal devices within the coverage range of the network device, the method further includes:

[0092] De-duplication and merging the first time-sensitive network TSN identification list or the master clock source identification list of the devices connected to the master clock source in the multiple terminal devices to obtain a first target TSN identification list or a first target master clock source identification list, and sending the first target TSN identification list or the first target master clock source identification list to the neighboring network device; and / or

[0093] The second time-sensitive network TSN identification list or the non-master clock source identification list of the devices connected to the non-master clock source in multiple terminal devices is de-duplicated and merged to obtain a second target TSN identification list or a second target master clock source identification list, and the second target TSN identification list or the second target master clock source identification list is sent to the neighboring network device.

[0094] It should be noted that the first time-sensitive network TSN identification list or the master clock source identification list of the devices connected to the master clock source in the multiple terminal devices are de-duplicated and merged respectively, that is, the first time-sensitive network TSN identification list of the devices connected to the master clock source in the multiple terminal devices is merged in the region to obtain the first target TSN identification list, and the master clock source identification list of the devices connected to the master clock source in the multiple terminal devices is de-duplicated and merged to obtain the first target master clock source identification list. In addition, the second time-sensitive network TSN identification list or the non-master clock source identification list of the devices connected to the non-master clock source in the multiple terminal devices are de-duplicated and merged respectively to obtain the second target TSN identification list or the second target master clock source identification list, that is, the second time-sensitive network TSN identification list of the devices connected to the non-master clock source in the multiple terminal devices is de-duplicated and merged to obtain the second target TSN identification list, and the non-master clock source identification list of the devices connected to the non-master clock source in the multiple terminal devices is de-duplicated and merged to obtain the second target master clock source identification list.

[0095] As an example, after receiving the first message sent by multiple terminal devices within the coverage of the network device, the method further includes:

[0096] Sending a second message to a neighboring network device;

[0097] The second message may include at least one of the following:

[0098] A relationship configuration list between a network slice identification number list (NSSAI list) and a time-sensitive network TSN identification list (e.g., a first time-sensitive network TSN identification list and / or a second time-sensitive network TSN identification list);

[0099] A relationship configuration list between a network slice identification number list and a clock source identification list (e.g., a master clock source identification list and / or a non-master clock source identification list) (e.g., one or more time-sensitive network identification lists to which one or more network slice identification numbers can be applied);

[0102] The accuracy information of the master clock source corresponding to the master clock source identification list;

[0103] Granularity information of the master clock source corresponding to the master clock source identifier list.

[0104] In one embodiment, after receiving first messages sent by multiple terminal devices within the coverage range of the network device, the method further includes:

[0105] Configuring a first radio network temporary identifier (RNTI) for a device connected to a master clock source among multiple terminal devices, and configuring a second RNTI for a device connected to a non-master clock source among multiple terminal devices;

[0106] A first RNTI is sent to a device connected to a master clock source among multiple terminal devices, and a second RNTI is sent to a device connected to a non-master clock source among multiple terminal devices.

[0107] If the first terminal device is a device connected to the master clock source among multiple terminal devices, the network device can send a first RNTI to the first terminal device, and the first terminal device can scramble the clock synchronization information packet based on the first RNTI and send it to the network device. The network device can descramble the packet based on the first RNTI to obtain the clock synchronization information packet. If the multiple second terminal devices are multiple devices connected to a non-master clock source among multiple terminal devices, the network device can send a second RNTI to the multiple second terminal devices. After the network device scrambles the clock synchronization information packet using the second RNTI and sends it to each second terminal device, the second terminal device can descramble the packet based on the second RNTI to obtain the clock synchronization information packet, thereby achieving clock synchronization.

[0108] As an example, a second RNTI may be configured for a device belonging to the same TSN, for example, the first TSN, among multiple terminal devices that are connected to a non-master clock source. The first RNTI and the second RNTI may be the same or different.

[0109] As an example, the network device may send a first RNTI through a second RRC signaling or a first MAC CE (Media Access Control Control Element) signaling, may send a second RRC signaling or a first MAC CE signaling to send the first RNTI to a device connected to a main clock source among multiple terminal devices, and the second RRC signaling or the first MAC CE signaling carries the first RNTI, and may send a third RRC signaling or a second MAC CE signaling to send a second RNTI to a device connected to a non-main clock source among multiple terminal devices, and the third RRC signaling or the second MAC CE signaling carries the second RNTI.

[0110] As an example, the second RRC signaling and the third RRC signaling may include but are not limited to RRC setup (RRCSetup), RRC recovery (RRCResume), RRC reconfiguration (RRCReconfiguration), etc. In one example, the format of the first MAC CE signaling and the second MAC CE signaling is as follows: Figure 2 shown.

[0111] In one embodiment, after receiving first messages sent by multiple terminal devices within the coverage range of the network device, the method further includes:

[0112] Based on the first public protocol data unit session PDU Session identifier and / or service quality flow identifier sent by the core network, data radio bearer DRB and / or logical channel are allocated, and configuration information of DRB and / or logical channel is sent to multiple terminal devices.

[0113] The network device can allocate DRBs and / or logical channels to multiple terminal devices based on the first common protocol data unit session (PDU) session identifier and / or quality of service (QoS) flow identifier sent by the core network.
