[0032] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the DS-TT information transmission method, terminal equipment, base station equipment, core network equipment, and computer-readable medium provided in the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

On the contrary, the purpose of providing these embodiments is to make the present disclosure thorough and complete, and will enable those skilled in the art to fully understand the scope of the present disclosure.

[0034] The accompanying drawings of the embodiments of the present disclosure are used to provide a further understanding of the embodiments of the present disclosure, and constitute a part of the specification, and are used together with the detailed embodiments to explain the present disclosure, and do not constitute a limitation of the present disclosure. By describing the detailed embodiments with reference to the accompanying drawings, the above and other features and advantages will become more apparent to those skilled in the art.

[0035] The present disclosure may be described with reference to plan views and / or cross-sectional views by means of ideal schematic views of the present disclosure. Therefore, the exemplary illustrations may be modified according to manufacturing techniques and / or tolerances.

[0037] The terms used in the present disclosure are only used to describe specific embodiments and are not intended to limit the present disclosure. The term "and / or" as used in the present disclosure includes any and all combinations of one or more related enumerated items. The singular forms "one" and "the" as used in the present disclosure are also intended to include plural forms, unless the context clearly indicates otherwise. The terms "including", "made of..." as used in the present disclosure specify the presence of the features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or groups thereof.

It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined in this disclosure.

[0039] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications of the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.

[0040] Time Sensitive Networking (TSN) is a network that can achieve deterministic minimum time delay and is widely used in industrial automation, Internet of Things and other fields.

[0041] Since TSN is mostly a local network within a small range, TSN needs to be integrated with conventional communication networks (such as 5G networks) to achieve large-scale coverage and applications; but the communication network is a "non-deterministic" network, and TSN is a "deterministic" network, and the two cannot be directly connected.

[0042] For this purpose, refer to Figure 8On the terminal side, TSN is connected to the terminal equipment (UE, User Equipment) in the communication network through the device-side time-sensitive network translator (DS-TT, Device-Side TSN Translator), and the terminal equipment is connected to the base station equipment (such as (R)AN) in the communication network; on the network side, TSN is connected to the core network equipment in the communication network through the network-side time-sensitive network translator (NW-TT, NetWork-side TSN Translator), such as the user plane function module (UPF, User Plane Function) connected to the 5G core network equipment (5GC).

[0043] It should be understood that 5GC also includes other functional modules such as session management function module (SMF, Session Management Function), access and mobility management function module (AMF, Access and mobility Management Function), policy control function module (PCF, Policy Control Function), unified data management function module (UDM, Unified Data Management), and authentication service function module (AUSF, Authentication Server Function).

[0044] In some related technologies, the terminal device sends DS-TT information to the core network device through specific signaling, such as referring to Fig. 9 When establishing a 5G session, the terminal device sends the DS-TT information to AMF through NAS signaling, and AMF sends the DS-TT information to SMF. SMF, as a manager, processes the DS-TT information and NW-TT information (such as obtained through UPF) and realizes integration with TSN based on this information. For example, the communication network as a whole can be used as a bridge to transmit TSN information and record the transmission delay to ensure the deterministic requirements of TSN.

[0045] However, the terminal device needs the support of its chip hardware to send NAS signaling to AMF, and the chips of many terminal devices do not have the function of sending NAS signaling to AMF, which makes it impossible to transmit DS-TT information to the core network equipment. Therefore, the integration of TSN and communication network cannot be achieved through these terminal devices.

[0046] In a first aspect, an embodiment of the present disclosure provides a method for transmitting DS-TT information based on a terminal device.

[0047] The method of the embodiment of the present disclosure is used to transmit DS-TT information during the process of integrating a communication network (such as a 5G network) with a TSN, which is executed by a terminal device (UE) in the communication network, which is connected to the DS-TT and a base station device (such as a (R)AN) respectively.

[0048] Reference Figure 1 The DS-TT information transmission method of the embodiment of the present disclosure includes:

[0049] S101. Receive DS-TT information sent by DS-TT.

[0050] S102: Encapsulate the DS-TT information in a target uplink message.

[0051] S103: Send the target uplink message to the base station device.

[0052] In the disclosed embodiment, after receiving the DS-TT information from the DS-TT, the terminal device encapsulates it in an uplink message (target uplink message), and sends the target uplink message carrying the DS-TT information to the base station device, and the base station device further sends (transparently transmits) the target uplink message to the core network device (such as 5GC).

[0053] In the embodiment of the present disclosure, the terminal device sends the DS-TT information to the base station device through an uplink message, and then the base station device transparently transmits it to the core network device, that is, the DS-TT information is not transmitted through the control plane process, but is transmitted through the media plane process, etc.; because the terminal device must have the ability to send an uplink message to the base station device, the embodiment of the present disclosure does not require the hardware of the terminal device (such as a chip) to have specific functions, and the software can ensure that various terminal devices can achieve the integration of TSN and the communication network.

[0054] The specific forms of DS-TT information are various, but it should include various information required to realize the integration of communication network and TSN. For example, DS-TT information may include the fields shown in Table 1 below:

[0055] Table 1. Fields in DS-TT information

[0056]

[0057] In some embodiments, before sending the target uplink message to the base station device (S103), the method further includes:

[0058] S100: Establish a session with a core network device.

[0059] As one method of an embodiment of the present disclosure, the terminal device may first establish a communication network session (such as a 5G session) and then transmit the above target uplink message (DS-TT information).

[0060] In a second aspect, an embodiment of the present disclosure provides a method for transmitting DS-TT information based on a base station device.

[0061] The method of the embodiment of the present disclosure is used to transmit DS-TT information during the process of merging a communication network (such as a 5G network) with TSN, which is executed by a base station device (such as (R)AN) in the communication network, and the base station device is connected to a terminal device (UE) and a core network device (such as 5GC) respectively.

[0062] Reference Figure 2 The DS-TT information transmission method of the embodiment of the present disclosure includes:

[0063] S201. Receive a target uplink message sent by a terminal device.

[0064] The target uplink message includes DS-TT information.

[0065] S202: Send the target uplink message to the core network device.

[0066] In the disclosed embodiment, the base station device receives a target uplink message containing DS-TT information. Since the target uplink message is also an uplink message, the base station device will continue to send (transmit) it to the core network device, so that the core network device can obtain the DS-TT information through the base station device.

[0067] In a third aspect, an embodiment of the present disclosure provides a method for transmitting DS-TT information based on a core network device.

[0068] The method of the embodiment of the present disclosure is used to transmit DS-TT information during the process of merging a communication network (such as a 5G network) with TSN, which is executed by a core network device (such as 5GC) in the communication network, and the core network device is connected to a base station device (such as (R)AN).

[0069] Reference Figure 3 The DS-TT information transmission method of the embodiment of the present disclosure includes:

[0070] S301: Receive a target uplink message sent by a base station device.

[0071] The target uplink message includes DS-TT information.

[0072] S302: Process DS-TT information.

[0073] In the disclosed embodiment, after the core network device receives an uplink message from the base station device, if it is found that the message contains DS-TT information, it is determined that the message belongs to the target uplink message, and the DS-TT information can be parsed out for processing to achieve integration with TSN.

[0074] In some embodiments, the core network equipment includes UPF and SMF.

[0075] Receiving a target uplink message sent by a base station device (S301) includes:

[0076] S3011. UPF receives the target uplink message sent by the base station device, parses the DS-TT information from the target uplink message, and sends a target message including the DS-TT information to SMF.

[0077] Processing DS-TT information (S302) includes:

[0078] S3021. SMF receives the target message, parses the DS-TT information from the target message and processes it.

[0079] As one embodiment of the present disclosure, refer to Figure 8 The core network device can be specifically in the form of 5GC, so that it includes UPF and SMF, and UPF is connected to the base station device; therefore, UPF can specifically receive the target uplink message from the base station device and parse the DS-TT information therefrom, and then send the DS-TT information to SMF in the form of a target message, so that SMF can process the DS-TT information to achieve integration with TSN.

[0080] It should be understood that the UPF may also be connected to the NW-TT and may receive NW-TT information from the NW-TT, and may thereby also send the NW-TT information to the SMF (eg, together with the DS-TT information).

[0081] In some embodiments, the target message comprises a session report request message.

[0082] As one method of an embodiment of the present disclosure, the target message sent by the above UPF to the SMF may be a session report request message (Session Report Request) transmitted through the N4 port.

[0083] Example:

[0084] The overall process of the DS-TT information transmission method according to an embodiment of the present disclosure is introduced below.

[0085] The architecture of TSN and communication network applicable to the embodiments of the present disclosure can be referred to as Figure 8 .

[0086] Reference Fig.10 , Fig.11 The DS-TT information transmission method of the embodiment of the present disclosure includes:

[0087] A1. Launch a 5G session.

[0088] UE completes the 5G session online through interaction with 5GC.

[0089] A2. The UE sends the DS-TT information to the (R)AN.

[0090] The UE receives the DS-TT information of the DS-TT, and encapsulates the DS-TT information in a target uplink message (UL User Data) and sends it to the (R)AN.

[0091] A3. (R)AN sends the target uplink message to UPF.

[0092] After receiving the UL User Data, (R)AN transparently transmits it to the UPF of 5GC.

[0093] A4. UPF passes the DS-TT information in the target uplink message to SMF.

[0094] After UPF finds that the received UL User Data contains DS-TT information, it adds the DS-TT information to the private field of SessionReport Request and sends it to SMF through the N4 port as the target message.

[0095] For example, the above private fields may be in the form of Table 2:

[0096] Table 2. Private fields of target message

[0097]

[0098] Among them, after obtaining the DS-TT information, the UPF can also save it first, and after waiting to receive the NW-TT information, add the DS-TT information and the NW-TT information to the target message at the same time and send them to the SMF together.

[0099] A105. After successfully receiving the target message, SMF sends a response message to UPF.

[0100] After SMF successfully receives and processes the Session Report Request, it sends a response message (SessionReport ACK) to UPF.

[0101] A106. SMF processes the acquired DS-TT information.

[0102] SMF merges with TSN based on the content of DS-TT information parsed from the private field of the target message.

[0103] It should be understood that each device and module in the embodiments of the present disclosure should have the ability to implement the respective steps.

[0104] For example, the UE needs to be able to send DS-TT information to the (R)AN, and the (R)AN needs to be able to send the DS-TT information to the UPF. The UPF needs to be able to parse the DS-TT information in the uplink message and send it to the SMF. The SMF needs to be able to parse the DS-TT information from the private field of the target message and process it.
