[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] The term "comprise" and any variation thereof in the specification and claims of the present application are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. In addition, the use of "and / or" in the specification and claims to indicate at least one of the connected objects, such as A and / or B, means that A alone, B alone, and A and B exist in three cases.

[0061] In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0062] The following is an introduction to an embodiment of the present invention in conjunction with the accompanying drawings. The information transmission method and communication device provided in the embodiment of the present invention can be applied to a wireless communication system. The wireless communication system can be a 5G system, or an evolved long term evolution (eLTE) system, or a subsequent evolution communication system.

[0063] In the embodiment of the present invention, time sensitivity (Time Sensing) may also be referred to as periodic deterministic (Periodic deterministic). Time sensitive communication may also be referred to as periodic deterministic communication. Time sensitive data stream may also be referred to as periodic deterministic data stream. A time sensitive network technology such as IEEE TSN (Time Sensing Network). Periodic deterministic communication is data transmission with a transmission interval as a period.

[0064] refer to Figure 1 , is a schematic diagram of an architecture of a wireless communication system applicable to an embodiment of the present invention. In an embodiment of the present invention, a time-sensitive data stream transmitter may be called a talker, and a time-sensitive data stream receiver may be called a listener. Data may be forwarded between a talker and a listener through one or more bridges. An end station node (End Station) may be a talker or a listener. A bridge (Bridge) is responsible for data transmission between a talker and a listener.

[0065] The terminal (such as User Equipment, UE), the time-sensitive adapter and the wireless communication network form a bridge (the 5G bridge will be used as an example later). For downlink data, the port of the device-side time-sensitive network adapter (Device-side TSN translator, DS-TT) can be the data egress port, and the port of the network-side time-sensitive network adapter (Network-side TSN translator, NW-TT) is the data ingress port. For uplink data, the port of NW-TT can be the data ingress port, and the port of DS-TT is the data egress port. The terminal can be co-located with DS-TT. The user plane function (UserPlane Function, UPF) can be co-located with NW-TT.

[0066] like Figure 1As shown, 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 a proxy 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 to the TSN bridge (TSN Bridge) and / or the end station (End Station) respectively. Through the 5G bridge, the TSN bridge and / or the end station connected to the port of the TT can communicate.

[0067] It should be noted that Figure 1 This is only an example diagram. In the embodiment of the present invention, the structure of the 5G bridge and the connection relationship between the ports in the 5G bridge are not limited.

[0068] In order to support the implementation of the bridge composed of terminals, time-sensitive adapters and wireless communication networks, the following problems need to be solved

[0069] Question 1: A DS-TT port can form a port pair with multiple NW-TT ports. For example, the ports on the DS-TT side are A1 and A2, and there are B1, B2, and B3 on the NW-TT. Then the port pairs can be [A1, B1], [A1, B2], [A1, B3], [A2, B1], [A2, B2], [A3, B3]. Currently, the AF calculates the delay of different port pairs, and the delay of the port pair is the time required for a data packet to pass from one port of the port pair to another port. It is not difficult to understand that there can be three types of port pairs: a port pair consisting of two DS-TT ports, a port pair consisting of a DS-TT port and a NW-TT port, and a port pair consisting of two NW-TT ports. It is not difficult to understand that the delay calculations of the three types of port pairs are different. Therefore, in order to form a port pair and determine the delay of the port pair, the TT type of the port is required. However, currently, the AF does not distinguish between DS-TT ports and NW-TT ports.

[0070] Question 2: When calculating the delay between a port pair consisting of a DS-TT port and a NW-TT, the processing time between the terminal and the DS-TT (UE to DS-TT residence time) plus the packet delay budget (Packet Delay Budget, PDB) is calculated.

[0071] The processing time between the terminal and DS-TT is the delay of the data packet passing between the DS-TT port and the terminal; it is related to the port of DS-TT. Packet Delay Budget (PDB) is the time it takes for a data packet to pass between the terminal and the NW-TT port, and should be related to the port of NW-TT. However, at present, PDB does not distinguish between the ports of NW-TT. In one embodiment, each port of NW-TT is configured with the same PDB, that is, the time it takes for a data packet to pass between the terminal and any NW-TT port is the same. In another embodiment, each port of NW-TT is configured with the same PDB but different PDBs. PDB distinguishes NW-TT ports.

[0072] Question 3: Different packets received from a NW-TT port may be sent to different DS-TT ports. Different DS-TT packets correspond to different PDU sessions, and the SMFs of different PDU sessions can be different. NW-TT currently lacks information to select a DS-TT port. UPF also lacks information to select a PDU session corresponding to a DS-TT port.

[0073] Question 4: Currently, there is no association between the NW-TT port and the PDU session of DS-TT, nor should there be an association. This is because different data packets received from a NW-TT port may be sent to different DS-TT ports; different data packets received from a DS-TT port may also be sent to different NW-TT ports. However, the port-related information of the NW-TT port is currently sent through the relevant signaling of the PDU session related to the DS-TT port. For example, the UPF sends the port-related information of the NW-TT port to the SMF of the PDU session related to the DS-TT port, and the SMF sends the port-related information of the NW-TT port to the PCF of the PDU session policy related to the DS-TT port. The PCF then sends the port-related information of the NW-TT port to the AF.

[0074] When DS-TT is not connected, the port-related information of NW-TT cannot be sent to AF when it is generated or updated. Therefore, it waits for the PDU session of DS-TT to be established before forwarding.

[0075] In the embodiment of the present invention, optionally, acquisition can be understood as generation, acquisition from configuration, reception, reception after request, acquisition through self-learning, acquisition by deduction based on information not received, or acquisition after processing based on received information, which can be determined according to actual needs and is not limited in the embodiment of the present invention. For example, when a certain capability indication information sent by a device is not received, it can be deduced that the device does not support the capability.

[0076] Optionally, the sending may include broadcasting, broadcasting in system messages, and returning after responding to requests.

[0077] Optional, pre-configured ones can be called default.

[0078] In an optional embodiment of the present invention, the port management container may also be called a port management information container. The port management container is a container that carries port control information (also called port management information).

[0079] In an optional embodiment of the present invention, the port related information includes: a port management container. In an optional embodiment of the present invention, the port related information can be understood as any one or more information about the port managed by the bridge (such as port related configuration information in bridge management in 802.1Q).

[0080] In an embodiment of the present invention, the port may be one of the following: an Ethernet port or an IP port.

[0081] In an optional embodiment of the present invention, the data channel may include but is not limited to one of the following: PDU session, PDN connection, QoS flow, bearer, Internet Protocol Security (IPsec) channel, wherein the bearer may be an evolved radio access bearer (Evolved Radio Access Bearer, E-RAB), a radio access bearer (Evolved Radio Access Bearer, RAB), a data radio bearer (Data Radio Bearer, DRB), a signaling radio bearer (signalling radio bearers, SRB), etc.

[0082] In an optional embodiment of the present invention, the port pair is composed of two ports, for example: two ports of the same DS-TT, or two ports of different DS-TTs, or two ports of the same NW-TT, or two ports of different NW-TTs.

[0083] In an optional embodiment of the present invention, the latency of a port pair (also referred to as the bridge latency of a port pair) may refer to the time it takes for a data packet to pass from one port to another port. The two ports may be two ports of the same bridge (such as a 5G bridge). It is not difficult to understand that the bridge latency may be the time overhead for a data packet to pass through the bridge.

[0084] For example, a first port pair is composed of a first port and a second port, and the delay of the port pair may refer to the time taken for a data packet to pass from the first port to the second port.

[0085] In an optional embodiment of the present invention, the port pair delay can be a bridge delay that distinguishes traffic classes. Each port can support one or more traffic classes. The transmission performance of each traffic class is different, so it is not difficult to understand that each traffic class of the outgoing port has a port pair delay. The port pair delay of each traffic class can be different.

[0086] That is to say, port delay may also refer to the bridge delay of a certain service class. Of course, the bridge delays of different service classes may be the same or different.

[0087] In an optional embodiment of the present invention, TT port, port of TT, port on TT, port on TT side, and TT side port represent the same meaning and can be used interchangeably.

[0088] In an optional embodiment of the present invention, the DS-TT port and the ports of DS-TT both represent ports located on the DS-TT and can be mixed; in an optional embodiment of the present invention, the NW-TT port and the ports of NW-TT both represent ports located on the NW-TT and can be mixed.

[0089] In an optional embodiment of the present invention, a DS-TT port may also be equivalent to a device side port; and an NW-TT port may also be equivalent to a network side port. When the TT type of a port is DS-TT, it may be equivalent to a port being a device side port; when the TT type of a port is NW-TT, it may be equivalent to a port being a network side port.

[0090] In an optional embodiment of the present invention, the relevant information of the TT where the first port is located may be referred to as the relevant information of the TT of the first port or the TT related information of the first port.

[0091] In an optional embodiment of the present invention, the data channel corresponding to the port is generally associated with a port of a DS-TT.

[0092] In an optional embodiment of the present invention, the wireless communication network may be referred to as a network for short.

[0093] In an embodiment of the present invention, the wireless communication network may be at least one of the following: a public network and a non-public network.

After determining the relevant information of the TT where the first port is located, the port-related information of the first port and the relevant information of the TT where the first port is located are sent. For example, when the SMF sends the port-related information of the first port to the PCF or the PCF sends the port-related information of the first port to the AF, the type of the TT where the first port is located is additionally included.

[0150] In another implementation manner, the port-related information of the first port does not include the delay-related information of the first port. After determining the delay-related information of the first port and / or determining the relevant information of the TT where the first port is located, the port-related information of the first port and the delay-related information of the first port are sent.
