[0004] In a Time Sensing Network (TSN), time-dependent data streams can be forwarded between senders and receivers via one or more bridges. In a time-synchronized network, a bridge can receive clock notification messages from different clocks on different ports, and the bridge itself also maintains a clock. The bridge compares the received clocks with its own system clock, selects the optimal clock as the master clock, and sends a notification message to communicate the selected master clock. Therefore, determining the optimal clock is a pressing issue in time-dependent services.

[0194] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0195] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. Furthermore, the term "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "and / or" relationship. For example, NW-TT / UPF can be a combined device.

[0196] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following description, although these technologies can also be applied to applications other than NR system applications, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0197] FIG1 shows a block diagram of a wireless communication system applicable to an embodiment of the present application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a terminal device or a user terminal (UE). The terminal 11 may be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (Pedestrian User Equipment, PUE) and other terminal-side devices. Wearable devices include: bracelets, headphones, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 can be a base station or a core network, where the base station can be called a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (Transmitting Receiving Point, TRP) or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0198] In the embodiments of the present application, time sensitivity may also be referred to as periodic deterministic. Time-sensitive communication may also be referred to as periodic deterministic communication. Time-sensitive data streams may also be referred to as periodic deterministic data streams. A time-sensitive network technology such as IEEE TSN (Time Sensing Network) transmits data periodically with a transmission interval as the periodicity.

[0199] In the embodiments of the present application, the transmitter of a time-sensitive data stream may be referred to as a talker, and the receiver of a time-sensitive data stream may be referred to as a listener. Data may be forwarded between the talker and the listener via one or more bridges. An end station node may be either a talker or a listener. A bridge is responsible for data transmission between the talker and the listener.

[0200] A terminal (such as User Equipment (UE), a time-sensitive adapter, and a communication network form a bridge (the 5G bridge will be used as an example later). For downlink data, the port of the device-side TSN translator (DS-TT) can be the data egress port, and the port of the network-side TSN translator (NW-TT) is the data ingress port. For uplink data, the port of the NW-TT can be the data ingress port, and the port of the DS-TT is the data egress port. The terminal can be co-located with the DS-TT. The user plane function (UPF) can be co-located with the NW-TT.

[0201] Optionally, a terminal can be connected to one or more DS-TTs, and a DS-TT can have one or more ports. A 5G bridge can have a UPF, and one or more ports can be enabled on the NW-TT of the UPF. The terminal can act as an agent for the port of the DS-TT and establish a protocol data unit (PDU) session with the UPF. Through the PDU session, the port on the DS-TT is associated with the port of the NW-TT jointly established by the UPF. The port of the DS-TT becomes a port of the 5G bridge. The ports of the DS-TT and the ports of the NW-TT can be connected separately to the TSN bridge (TSN Bridge) and / or the end station (End Station). Through the 5G bridge, the TSN bridge and / or the end station connected to the port of the TT can communicate.

[0202] Time-sensitive systems have high requirements for time synchronization and require that all clocks remain synchronized. However, there may be multiple master clocks in the network. To determine the optimal clock, 5G bridges must also solve the following problems:

[0203] Problem 1: In a 5GS bridge, the bridge's ports are located on both the DS-TT and the NW-TT. A 5G network can have multiple DS-TTs. Therefore, different DS-TTs and NW-TTs may receive notification messages from external clocks. Therefore, a centralized node is required to determine the optimal clock for the bridge.

[0204] An optional solution is to use the NW-TT as the central node. Upon receiving notification messages, the DS-TT forwards them to the NW-TT. The NW-TT then determines the master clock and the next-hop clock notification message based on the clock information collected on the DS-TT and NW-TT ports.

[0205] For example, when the local system clock is used as the master clock, the root clock in the clock notification message of the next hop is the local system clock, and the distance between the local system clock and the root clock is 0.

[0206] For example, when the clock in one of the received clock notification messages is used as the master clock, the root clock in the clock notification message of the next hop is the received clock, and the path overhead with the root clock (such as the number of hops from the root clock) is +1, and the port for sending the clock notification message is determined.

[0207] Question 2: According to the optimal clock selection algorithm, after receiving a clock notification message, a port derives a message priority vector. The message priority vector is compared with the port priority vector. If the message priority vector is not superior to the port priority vector, it is pointless for the DS-TT to forward the clock notification message or message priority vector to the NW-TT. This is because the clock cannot be considered a candidate for optimal clock selection. Sending the clock notification message or message priority vector is a waste of resources.

[0208] An optional solution is to configure the DS-TT to store the port priority vector of each port. The DS-TT compares the port priority vector with the message priority vector derived from the received notification message. Only when the message priority vector is superior to the port priority vector will the DS-TT send the notification message or message priority vector to the NW-TT; otherwise, the DS-TT discards the received notification message or message priority vector.

[0209] Question 3: The receiving port is one of the inputs for the optimal clock selection algorithm. If the notification message does not contain the receiving port information, how does NW-TT know the receiving port of the notification message?

[0210] When DS-TT sends a notification message, since there is no receiving port identification information in the notification message, DS-TT needs to let the UE send the notification message through the PDU session of the port that receives the notification message, so that the UPF can associate the outgoing port number through the PDU session. NW-TT derives the message priority vector based on the receiving port number and the notification message to proceed to the next step.

[0211] When DS-TT sends a message priority vector, it is included in the relevant port management container or DS-TT management container of the receiving port and sent because the message priority vector includes the message of the receiving port.

[0212] In one implementation, when the message priority vector is superior to the port priority vector, the DS-TT updates the port priority vector with the message priority vector and sends the updated port priority vector to the NW-TT.

[0213] On the other hand, multiple root bridges may exist in a network. 5G networks also need to solve the problem of how to determine the root bridge and generate paths based on the spanning tree algorithm. The problem and method of determining the optimal root bridge are similar to those of determining the master clock.

[0214] Problem 1: In a 5GS bridge, the bridge's ports are located on both the DS-TT and the NW-TT. A 5G network can have multiple DS-TTs. Therefore, different DS-TTs and NW-TTs may receive configuration messages from external root bridges. Therefore, a centralized node is required to determine the optimal root bridge for the network.

[0215] Problem 2: According to the spanning tree algorithm, after receiving a configuration message, a port derives a message priority vector. The message priority vector is compared with the port priority vector. If the message priority vector is not superior to the port priority vector, it is pointless for the DS-TT to forward the clock notification message or message priority vector to the NW-TT. This is because the DS-TT cannot be a candidate for optimal root bridge status. Sending the configuration message or message priority vector is a waste of resources.

[0216] Question 3: The receiving port is one of the inputs to the spanning tree algorithm. If the configuration message does not contain the receiving port information, how does the NW-TT know the receiving port of the notification message?

[0217] In the embodiment of the present application, the root object information and the root object information represent the same meaning and can be mixed.

[0218] Optionally, the root object may include at least one of the following: a master clock, a root bridge.

[0228] - receiving port information (which can indicate the port where the message is sent),

[0229] - The bridge ID of the transmitting bridge.

[0230] It's easy to understand that, for example, if System B receives the first message from System A, the transmitting bridge is System A, the outgoing port is System A's port, and the receiving port is System B's port. For example, if System B wants to send the second message to another system, in System B's priority vector, the transmitting bridge is System B, the outgoing port is System B's port, and the receiving port is System B's port.

[0231] Furthermore, the information of the root object includes but is not limited to one of the following: a root bridge identifier (Root Bridge Identifier), an identifier of the root system (rootSystemIdentity).

[0232] Furthermore, the path cost of the root object includes but is not limited to one of the following: Root Path Cost (path cost from the transport bridge to the root bridge), stepsRemoved (the number of connections in the path between the time-aware system and the root system).

[0233] Optionally, the path cost of the first root object may represent the path cost to the first root object. In one embodiment, the path cost of the first root object includes, but is not limited to, one of the following: first stepsRemoved (representing the number of connections in the path from the first root system to the time-aware system), or first Root Path Cost (the path cost from the transmission bridge to the first root bridge).

In one embodiment, the path cost of the best root object includes, but is not limited to, one of the following: a second stepsRemoved (representing the number of connections in the path from the best root system (i.e., the best master clock system) to the time-aware system), or a second Root Path Cost (the path cost from the transmission bridge to the best root bridge).

[0235] In one implementation, the priority vector may include at least one of the following information:

[0236] - Root Bridge Identifier The Bridge Identifier of the Bridge believed to be the Root by the transmitter.

[0237] -Root Path Cost (Root Path Cost, to that Root Bridge from the transmitting Bridge).

[0238] -Bridge Identifier of the transmitting Bridge.

[0239] - Information of the outgoing port (such as port identifier), the port through which the message was transmitted (Port Identifier, of the Port through which the message was transmitted).

[0240] -Information of the receiving port, the receiving port of the message (Port Identifier, of the Port through which the message was received).

[0241] In another embodiment, the priority vector includes at least one of the following information:

[0242] -The root system's identity, rootSystemIdentity.

[0243] - Root path cost (stepsRemoved): it is the number of links in the path from the root to the respective time-aware system.

[0244] - Information of the outgoing port, the port of the transmitting time-aware system that sends the message (sourcePortIdentity, i.e., portIdentity of the transmitting time-aware system).

[0245] -Information of receiving port portNumber of the receiving port.

[0246] In one embodiment, the system priority vector may include the priority vector of the root object currently used by the system. The system priority vector may also be called a bridge priority vector, and the bridge priority vector may include the priority vector of the root object currently used by the bridge.

[0247] In one embodiment, the path priority vector represents a priority vector associated with a path between root objects. The path priority vector includes, but is not limited to, one of the following: a priority vector associated with a path between master clocks (gmpath Priority Vector), a priority vector associated with a path between root bridges (root path priority vector),

[0248] Optionally, the path priority vector of the first root object represents a priority vector associated with the path between the first root object. For example, when system B receives the first message from system A, it generates the path cost between system B and the first root object based on the path cost between system A and the first root object and the path cost of system B's receiving port. The path cost between system B and the root object included in system B's path priority vector is the path cost between system B and the first root object.

[0249] Optionally, the path cost of the receiving port may be the path cost from system A (e.g., the egress port from which system A sends the first message) to system B (e.g., the port from which system B receives the first message). In one embodiment, as in the optimal clock algorithm, the path cost of the receiving port is one hop. The path priority vector is generated by adding 1 to the path cost with respect to the root object in the message priority vector or by adding 1 to the path cost with respect to the root object in the port priority vector of the replaced first port.

[0250] The second priority vector includes but is not limited to one of the following: a designated priority vector, a master priority vector. The second priority vector is a priority vector sent externally.

[0255] The auxiliary port state or the port of the receiving port may be a port that is not used to receive relevant messages (such as announce messages, configuration messages, and Sync messages). The relevant messages include information about the root object.

[0256] The ports in the passive port state may be ports other than the following ports: The following ports include ports in the following states: master port state (MasterPort), designated port state or sending port state, slave port state (Slave) or receiving port state, and unavailable port state.

The specific term "acquisition" may be determined based on actual needs and is not limited in the embodiments of the present application.

[0274] Step 21: Receive the first message.

[0275] In this embodiment, the first message is a message containing information about a first root object. The first root object may include at least one of the following: a first master clock, a first root bridge.

[0276] Optionally, the information of the first root object includes but is not limited to one of the following: a first root bridge identifier (Root Bridge Identifier) ​​and an identifier of the first root system (rootSystemIdentity).

[0277] Furthermore, the first root bridge may be a bridge that provides a first master clock.

[0278] Optionally, the first root information may include at least one of the following: a first message, a message priority vector, a port priority vector of a first port, a path priority vector of a first root object, information of the first port, and a path overhead of a receiving port.

[0279] In one embodiment, the first message is a first message received from a DS-TT port and / or an NW-TT port. In another embodiment, the first message is a first message received from a data channel.

[0280] In one embodiment, the first root information includes, but is not limited to, one of the following: a first message, a message priority vector, a port priority vector of a first port, and a path priority vector of a first root object. It is understood that when the first root information includes the first message, it indicates that the first communications device sends the first message without processing it; and when the first root information includes the message priority vector, the port priority vector of the first port, and the path priority vector of the first root object, it indicates that the first communications device processes the first message before sending it.

[0281] In one implementation, the port priority vector of the first port may be a port priority vector after being replaced, and its value is the same as the message priority vector.

[0282] The first port includes a port for receiving the first message.

[0283] Optionally, the path cost of the receiving port may be the path cost from system A (e.g., the outgoing port through which system A sends the first message) to system B (e.g., the port through which system B receives the first message). System A is the system that sends the first message. System B is the system to which the first communication device belongs.

[0284] In one embodiment, as in the optimal clock algorithm, the path cost of the receiving port is 1 hop. The path priority vector can be generated by adding 1 to the path cost between the message priority vector and the root object or adding 1 to the path cost between the replaced first port and the root object in the port priority vector.

[0285] Furthermore, the information in the first message may include at least one of the following: information about the first root object, path cost to the first root object, identification information of the port from which the first message is sent, and information about the egress port. Specifically, the egress port is the port from which the first message is sent.

[0286] Furthermore, the message priority vector includes at least one of the following: information of the first root object, path cost of the first root object, information of the egress port, information of the receiving port, and a bridge identifier of the transmitting bridge.

[0287] Optionally, the path cost of the first root object may represent the path cost between the first root object and the first root object.

[0290] generating a message priority vector according to the first message and / or the first port;

[0291] discard the first message;

[0292] Second type of operation in the first operation.

[0293] Optionally, the message priority vector may include at least one of the following: information in the first message, port identifier information of the first port, information about the first root object, the path cost of the first root object, information about the egress port, information about the receiving port, and a bridge identifier of the transmitting bridge. Specifically, the egress port is the port that sends the first message. The receiving end is the port that receives the first message.

[0294] Optionally, the path cost of the first root object may represent the path cost between the first root object and the first root object.

[0295] When the first communication device is a DS-TT, the first port may include a port on the first communication device.

[0296] When the first communications device is an NW-TT, the first port may include a port on the NW-TT and / or a port on a DS-TT. When the first port is a port on a DS-TT, the first communications device may obtain information about the first port based on the port associated with the data channel through which the first message was received. For example, the NW-TT may obtain information about the first port from the UPF; the UPF may obtain information about the first port based on the port associated with the data channel through which the first message was received.

[0297] Furthermore, the second type of operation in the first operation may include at least one of the following:

[0298] generating a path priority vector of the first root object based on the first port, the first message and / or the path cost of the receiving port, or generating a path priority vector of the first root object based on the message priority vector and / or the path cost of the receiving port;

[0299] Sending a first message to a first target end;

[0300] The port priority vector of the first port is replaced with the message priority vector.

[0301] Optionally, the first port includes a port for receiving a first message.

[0302] In one implementation, the first port is a port on a DS-TT.

[0303] In another embodiment, the first port is a port on the NW-TT.

[0304] Optionally, the first target end may include but is not limited to at least one of the following: terminal, UPF, NW-TT, AF.

[0305] Optionally, the first message may include a notification message (such as an announce message in the gPTP protocol) and / or a configuration message (such as a configuration message in the spanning tree protocol).

[0306] In this embodiment, the port status may include one of the following: master port status (Master), designated port status or sending port status, slave port status (Slave) or receiving port status, passive port status, and unavailable port status.

[0307] The port status information may include all port status information on the DS-TT and / or NW-TT in the bridge.

[0308] In the embodiment of the present application, the second type of operation in the first operation can be performed when a first condition is met, wherein the first condition includes: the message priority vector is greater than or equal to the port priority vector of the first port.

[0309] Optionally, performing the first operation may include discarding the first message if a second condition is met, wherein the second condition includes that the port priority vector of the first port is greater than or equal to the message priority vector.

[0310] Furthermore, the method further includes: not executing the second type of operation in the first operation if a second condition is met, wherein the second condition includes: the port priority vector of the first port is greater than or equal to the message priority vector.

[0311] In the embodiment of the present application, the first root information may be included in a first container and sent. Optionally, the first container may include one of the following: a port management information container of the first port, and a DS-TT management information container.

[0312] In one embodiment, when the first root information is sent through the first container, the first target end may be AF. At this time, the first root information may include at least one of the following: a message priority vector, a port priority vector of the first port, a path priority vector of the first root object, information of the first port, and a path overhead of the receiving port.

[0313] Furthermore, after receiving the first root information from the first container, the AF may include all or part of the first root information in a second container and send it, as specifically described in the embodiment of FIG4 .

[0314] In an embodiment of the present application, the first root information may be sent to the first target end via a first data channel. Optionally, the first data channel is a data channel associated with the first port, or a data channel associated with any DS-TT port.

[0315] In one implementation, when the first root information is sent through the first data channel, the first target end may be a UPF and / or an NW-TT, and the first root information may include a first message.

[0316] Furthermore, the sending of the first root information to the first target end through the first data channel may include: the terminal sending the first root information to the first target end through the first data channel.

[0317] It should be noted that the first communication device, such as DS-TT, can also obtain the second root information and perform the third operation according to the second root information. The detailed process of this can be found in the embodiment shown in Figure 4 and will not be repeated here.

[0318] It is not difficult to understand that in this embodiment, the NW-TT can serve as the central node. After receiving the first message (such as a notification message related to the master clock or a configuration message related to the root bridge) on the DS-TT port, it is sent to the NW-TT. Based on the root object information collected on the DS-TT port and the NW-TT port, as well as the root object of the system, the NW-TT determines the optimal root object (such as the master clock or root bridge) and the second message to be sent to the next hop (such as a notification message related to the master clock or a configuration message related to the root bridge). Furthermore, the DS-TT port can generate a message priority vector and send it to the AF, which forwards it to the NW-TT; or the DS-TT can send the first message to the UE, which then sends it to the UPF / NW-TT via a PDU session. The UE can choose to send the PDU session of the receiving port so that the NW-TT can generate a message priority vector or a path priority vector. The next hop message, that is, the second message, can be generated directly by the NW-TT; or the NW-TT can generate a second priority vector (such as a primary priority vector or a designated priority vector) and send it to the target port. The target port compares the port priority vector and the second priority vector and generates the second message. In this way, it can support the selection and acquisition of the best root object clock in the distributed TT structure of 5G bridges.

[0319] Referring to FIG3 , an embodiment of the present application provides an information control method, which is applied to a second communication device. The second communication device includes, but is not limited to, an NW-TT. In another embodiment, the second communication device may also be one of the following: a DS-TT, an AF. The method includes:

[0320] Step 31: Receive the first message.

[0321] In this embodiment, the first root information may include at least one of the following: a first message, a message priority vector, a port priority vector for a first port, a path priority vector for a first root object, information about the first port, and a path cost for a receiving port. The details are as described in the embodiment of Figure 2 and are not further described here. The first root object may include at least one of the following: a first master clock and a first root bridge.

[0322] Furthermore, the first root bridge may be a bridge that provides a first master clock.

[0323] Optionally, the first message is a message containing information about the first root object.

[0324] The first port includes a port for receiving a first message.

[0325] Step 32: Execute a second operation according to the first root information.

[0326] Optionally, the second operation may include at least one of the following:

[0327] generating a message priority vector according to the first message and / or the first port;

[0328] Generate a path priority vector of the first root object based on the first port, the first message, and / or the path cost of the receiving port; or generate a path priority vector of the first root object based on the message priority vector and / or the path cost of the receiving port (it is understood that the message priority vector may be received or generated); or generate a path priority vector of the first root object based on the port priority vector of the first port and / or the path cost of the receiving port (it is understood that the receiving port here is the first port);

[0329] The second type of operation in the second operation.

[0330] Furthermore, the second type of operation in the second operation may include at least one of the following:

[0331] Determine the best root object; for example, the best root object can be the best master clock or the best root bridge;

[0332] Determine the second root information;

[0333] Send a second message to the second destination.

[0334] Optionally, the second target end may include but is not limited to at least one of the following: terminal, UPF, DS-TT, AF.

[0335] Optionally, the second root information may include at least one of the following: a second message, a second priority vector, information about a second port, and configuration information about a port status.

[0336] Optionally, the second message is a message including information about the best root object, for example, the best root object is a best master clock or a best root bridge.

[0337] Optionally, the second port may include at least one of the following: a port for sending a second message, a port for sending a second priority vector, a port for sending a second root message, a port whose port status is a master port, a designated port, or a sending port. The master port is a port for sending the second message.

[0338] In one implementation, the second communication device may designate a port whose port status is a master port, a designated port, or a sending port as the second port.

[0339] Optionally, the second priority vector is a priority vector containing information about the best root object.

[0340] In one embodiment, determining the optimal root object may include: when the path priority vector of the first root object is superior to or equal to the system priority vector and / or the message priority vector is superior to or equal to the port priority vector of the first port, adopting the first root object as the optimal root object. When multiple first root objects have path priority vectors superior to or equal to the system priority vector, selecting the optimal one from the multiple path priority vectors.

[0341] Optionally, the path priority vector of the first root object is a priority vector corresponding to a path between a system or a bridge and the first root object, for example, a priority vector corresponding to a path between system B and the first root object, where system B is the system to which the second communication device belongs.

[0342] Optionally, the system priority vector may be a priority vector of a system to which the second communication device belongs or a priority vector of a bridge to which the second communication device belongs.
