Specific details for implementing the invention

[0043] The method and communication equipment supporting port control provided by the embodiments according to the present invention may be applied to a wireless communication system. The wireless communication system may be a fifth-generation (5G) mobile communication system, an evolved packet system (EPS), or a subsequent evolved communication system. The wireless communication network of the embodiments according to the present invention may be a fifth-generation mobile communication network (5GS) or an LTE network. Hereinafter, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the drawings attached to the embodiments of the present invention, and the embodiments described herein are not all embodiments of the present invention but only partial embodiments. All other embodiments obtained by a person skilled in the art without creative labor based on the embodiments of the present invention are all within the scope of protection of the present invention.

[0044] Referring to FIG. 1, FIG. 1 is a schematic diagram of the architecture of a wireless communication system according to some embodiment of the present invention.

[0045] The sender of a time-sensitive data stream is called a talker, and the receiver is called a listener. Data relay transmission between the talker and the listener is performed through one or more bridges. The end station can be either a talker or a listener. The bridge is responsible for data transmission between the talker and the listener.

[0046] A bridge is configured by User Equipment (UE), a time-sensitive adapter, and a wireless communication network (hereinafter referred to as the first bridge). For downlink data, the first adapter is the bridge exit and the second adapter is the bridge inlet. For uplink data, the first adapter is the bridge inlet and the second adapter is the bridge exit.

[0047] The first adapter is an adapter for a time-sensitive network on the equipment side (e.g., DS-TT). The ports of the first adapter may be used to connect other bridges or End Stations. The second adapter is an adapter for a time-sensitive network on the network side (e.g., NW-TT). The ports of the second adapter may be used to connect other bridges or End Stations.

[0048] The first adapter and / or the second adapter may be adapters of a time-sensitive network. Adapters of a time-sensitive network may also be Time Sensing Networking (TSN) translators.

[0049] The UE can be integrated with the first adapter. The User Plane Function (UPF) can be integrated with the second adapter.

[0050] The UE can act as a proxy for the first adapter to establish a Protocol Data Unit (PDU) session with the UPF. Through the PDU session, a port of the first adapter and a port of the second adapter of the UPF are connected. The port of the first adapter becomes a port of the first bridge.

[0051] Referring to FIG. 2, when there is a lack of wired connections in the equipment of a time-sensitive network, particularly in the equipment of both DS-TT and NW-TT, a bridge configured by a wireless communication system can connect the equipment of the same time-sensitive network through the ports of the device-side TSN translator (DS-TT) and the network-side TSN translator (NW-TT).

[0052] To support bridge port configuration, the following requirements must be addressed:

[0053] 1) To transmit time-sensitive data streams to the End Station within a limited delay, the path through which the time-sensitive data stream passes—namely, the ports of the bridge and bridge—must be determined before the data is transmitted. In a centralized architecture, the CNC (Control Plane Node of the time-sensitive network) performs routing configuration for the data streams on the bridge ports (for example, if the bridge uses the Spanning Tree Protocol, it configures a Static Filtering Entry, and if the bridge supports redundant paths, it configures a static tress). The routing configuration may be for Media Access Control (MAC) addresses and Virtual Local Area Network (VLAN) IDs, etc., that can pass through the ports. After the configuration is complete, the data stream carrying the said MAC address and VLAN ID can be relayed through the said ports.

[0054] 2) A bridge can receive non-time-sensitive data flows. To transmit time-sensitive data flows to the End Station within a limited delay, time-sensitive data flows must have a relatively high priority during bridge scheduling. Instead, the priority of non-time-sensitive data flows can be lowered to a relatively low priority (e.g., priority 0). In this case, a Priority Regeneration Table (or Priority Regeneration Override Table) must be configured for the port to remap the priorities.

[0055] 3) In a centralized architecture, information related to the transmission selection algorithm and bandwidth availability parameters can be configured for the bridge ports.

[0056] Problem: Regarding the requirements of 1), 2), and 3), if the bridge is configured by a UE, a time-sensitive adapter, and a wireless communication network, before the first adapter is connected to the wireless communication network through the UE and becomes a component of the bridge, it is not possible to perform pre-configuration on the ports of the first adapter on the one hand, nor is it possible to read the relevant configuration information of the first adapter ports on the other. Furthermore, some bridge configuration information, such as distinguishing ports or different traffic classes of ports, can be configured directly on the ports. Other bridge configuration information applies to the entire bridge, and how to apply it to the individual ports of the bridge is also an urgent task.

[0057] Optionally, acquisition may be understood as acquisition from a configuration, reception, reception via a request, acquisition through self-learning, acquisition derived based on unreceived information, or acquisition after processing based on received information; specifics are determined based on actual demand, and some embodiments of the present invention are not limited thereto. For example, if certain capability instruction information transmitted by the equipment is not received, it may be indicated that the equipment does not support the corresponding capability.

[0058] Optionally, the transmission may include a broadcast, a broadcast among system messages, or a response to a received request.

[0059] In one optional embodiment of the present invention, the port may be an Ethernet port.

The technology described in this specification may be applied to other systems and wireless technologies as well as the above systems and wireless technologies.

[0078] Referring to FIG. 3, some embodiments of the present invention provide a method for supporting port control applied to a first communication device. The first communication device includes, but is not limited to, at least one of a UE, a first adapter (e.g., DS-TT), a second adapter (e.g., NW-TT), and a UPF. The method comprises steps 31 and 32.

[0079] Step 31: Receive port-related control information.

[0080] Step 32: Perform port-related operations on the port according to the above port-related control information.

[0081] In some implementations, port-related operations include, but are not limited to, at least one of configuring the port, controlling whether to relay the data flow, controlling the scheduling of the data flow, controlling the queuing of the data flow, and controlling the regeneration of the priority of the data flow. In one implementation, configuring the port can be understood as performing a write operation on the corresponding control information of the port.

[0082] In some implementations, the above port is a port used as an outlet.

[0083] In some implementations, the port is a port of the first adapter. In this case, the first adapter and / or the UE can receive configuration information of the port.

[0084] In some other implementations, the port is a port of a second adapter. In this case, the second adapter and / or UPF can receive relevant control information of the port.

[0085] In some implementations, the first communication equipment receives the port-related control information from a port-related information container.

[0086] Optionally, the step of receiving port-related control information includes the step of receiving a port-related information container, wherein the port-related information container includes the port-related control information.

[0087] In some implementations, the UE receives port-related control information from the network. The UE transmits port-related control information to the first adapter. The first adapter receives port-related control information from the UE.

[0088] Optionally, port-related control information may include at least one of a port identifier, traffic class information, first routing information, priority regeneration information, port transmission speed information, bandwidth availability parameter information, and transmission selection algorithm information.

[0089] In some implementations, a unique port can be identified through bridge identifiers and port identifiers.

[0090] Optionally, the port identifier includes at least one of a bridge identifier, a port number, and a MAC address of the port. It is not difficult to understand that multiple ports of the first adapter and / or the second adapter can be connected to multiple bridges, and that a unique port can be identified through the bridge identifier and the port identifier.

[0091] Optionally, traffic class information is used to indicate different traffic classes. The value of a traffic class can be an integer from 0 to 7, each representing a different service type. A single port can have up to 8 traffic classes. When port-related control information includes both a port identifier and traffic class information, the traffic class indicated by the traffic class information is the traffic class of the port indicated by the port identifier.

[0092] In some implementations, port-related control information is port-level control information. In other implementations, port-related control information is traffic class-level control information. For example, traffic class-level control information may include at least one of information related to bandwidth availability parameters and information related to a transmission selection algorithm. Port-level control information may include at least one of first routing information, information related to priority regeneration, and information related to port transmission rates. For port-level control information, a port identifier must be included simultaneously.

[0093] In one encoding implementation method, port-related control information includes a port identifier and one or more control information (control information at the port level and / or traffic class level). It is not difficult to understand that all of the control information is related to the control information of the port indicated by the corresponding port identifier. In another encoding implementation method, port-related control information includes one or more control information, and each control information includes a port identifier. It is not difficult to understand that all of the control information is related to the control information of the port indicated by the port identifier among the control information. In this case, the ports corresponding to different control information may differ. Traffic class information is also similar to the encoding implementation method, so a description is omitted here.

[0094] Optionally, the first routing information may be static routing information (e.g., Static Filtering Entry or static tree).

[0095] The first routing information may include at least one of a port identifier, Media Access Control (MAC) address-related information (e.g., MAC address rules), Virtual Local Area Network (VLAN) identifier information (e.g., VLAN identifier rules), and control information for port operations. In one implementation, the first routing information is routing information for data flow at the port.

[0096] The control information for the above port operation can be understood as the port operation when the target address and / or virtual LAN identifier (VID) of the data flow corresponds to the MAC address information and / or VLAN identifier information.

[0097] Further, the control information of the above port operation includes at least one of the following.

[0098] - Relay transmission regardless of the presence or absence of other filtering information (e.g., dynamic filtering information).

[0099] - Filters regardless of the presence or absence of other filtering information (e.g., dynamic filtering information).

[0100] - Relay transmission or filtering is performed according to other filtering information. For example, when dynamic filtering information exists, relay transmission or filtering is performed according to the dynamic filtering information, or when dynamic filtering information does not exist, relay transmission or filtering is performed according to the default group filtering operation.

[0101] In some implementations, filtering can be referred to as non-relay transmission or discarding.

[0102] Priority regeneration information may be referred to as a Priority Regeneration Table or a Priority Regeneration Override Table. Optionally, priority regeneration information may include a first priority (also called a receive priority) and a second priority (also called a regeneration priority). Priority regeneration information is used to map the priority of a data flow with the first priority to the second priority (e.g., one of the integer values ​​between 0 and 7). The first priority and the second priority may be the same or different.

[0103] Further, the priority regeneration information may further include a port identifier, and the priority regeneration information may be used to indicate that it is valid at the port indicated by the port identifier.

[0104] In one implementation method, the packet header or flow information of the data flow includes a first priority, and when the port decides to relay the data flow, the first priority of the packet header is replaced with a second priority according to the priority regeneration table, and then the relay transmission is performed.

[0105] Optionally, portTransmitRate related information includes at least one of a port identifier and a port transmit rate.

[0106] Information related to bandwidth availability parameters can be referred to as a bandwidth availability parameter table. Information related to bandwidth availability parameters may include at least one of additional bandwidth (deltaBandwidth), managed bandwidth (adminIdleSlope), actual bandwidth (operIdleSlope), traffic class measurement interval (classMeasurementInterval), traffic class fixed bandwidth (lockClassBandwidth), and traffic class information.

[0107] Among them, additional bandwidth can be reflected as a percentage of the port transmission speed and is bandwidth reserved for the queue of a specific traffic class (e.g., the traffic class indicated by the traffic class information).

[0108] Among them, managed bandwidth may be bandwidth reserved to manage queues of specific traffic classes (e.g., traffic classes indicated by traffic class information).

[0109] Among them, the actual bandwidth may be the actual bandwidth reserved for a queue of a specific traffic class (e.g., the traffic class indicated by the traffic class information).

[0110] In one implementation method, for a centralized architecture, information related to bandwidth availability parameters may include only managed bandwidth and traffic class information. In this case, the managed bandwidth may be the same as the actual bandwidth.

[0111] Information related to the transmission selection algorithm can be referred to as a transmission selection algorithm table. The information related to the transmission selection algorithm includes traffic class information and at least one of the transmission selection algorithms.

[0112] Further, the transmission selection algorithm may include, but is not limited to, a credit-based shaping algorithm, a strict priority transmission selection algorithm, and a manufacturer's proprietary transmission selection algorithm.

[0113] A single port can have up to 8 traffic classes, and the relay transmission and queue capabilities supported by each traffic class may differ. When receiving port identifiers, traffic class information, and transmission selection algorithm information at the same time, configuration of bandwidth transmission selection algorithm information can be performed for the traffic class of the specified port.

[0114] In some embodiments of the present invention, on the one hand, operation of a port of a wireless communication system bridge can be supported, and on the other hand, control information related to the port of the wireless communication system bridge can be disclosed externally (e.g., CNC), thereby supporting the implementation of a communication system bridge configured by a terminal, a time adapter, and a wireless communication network.

[0115] Referring to FIG. 4, some embodiments of the present invention provide a method for supporting port control applied to a first communication device. The first communication device includes, but is not limited to, at least one of a UE, a first adapter (e.g., DS-TT), a second adapter (e.g., NW-TT), and a UPF. The method comprises step 41.

[0116] Step 41: If the first condition is satisfied, port-related control information is transmitted.

[0117] In some implementations, port-related control information is port-level control information. In other implementations, port-related control information is traffic class-level control information.

[0118] In some implementations, the first condition may include at least one of receiving a request to read port-related control information; successfully establishing a PDU session associated with the port; and generating or updating port-related control information.

[0119] In some implementations, the first communication equipment receives a request to read the port-related control information from the port-related information container.

[0120] In some implementations, the above port is a port used as an outlet.

[0121] In some implementations, the port is a port of a first adapter. In this case, the first adapter and / or the UE may transmit control information related to the port.
