All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "comprises," "comprising," or any other variation thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means that at least one of the connected objects, such as a and/or B, means that three cases, a alone, B alone, and both a and B, exist.

In the present embodiments, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Embodiments of the present invention are described below with reference to the accompanying drawings. The information transmission method and the communication equipment provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, or an Evolved Long Term Evolution (lte) system, or a subsequent Evolved communication system.

In embodiments of the present invention, time Sensing may also be referred to as Periodic deterministic (Periodic deterministic). Time-sensitive communications may also be referred to as Periodic deterministic communications (Periodic deterministic communications). A time-sensitive data stream may also be referred to as a periodic deterministic data stream. A Time sensitive Network technology such as IEEE TSN (Time Sensing Network). The periodic deterministic communication is data transfer with a transfer interval as a period.

Referring to fig. 1, a block diagram of an applicable wireless communication system according to an embodiment of the present invention is shown. In the embodiment of the present invention, a sending end of a time-sensitive data stream may be referred to as a talker, and a receiving end of the time-sensitive data stream may be referred to as a listener. the data forwarding between talker and listener may be performed via one or more bridges. The End Station node (End Station) may be a talker or a listener. The Bridge (Bridge) is responsible for data transfer between talker and listener.

The terminal (e.g., user Equipment, UE), the time-sensitive adapter, and the wireless communication network form a bridge (hereinafter, a 5G bridge is used as an example for description). For the downlink data, the port of the device side time-sensitive network adaptor (DS-TT) can be the output port of the data, and the port of the network side time-sensitive network adaptor (NW-TT) is the input port of the data. For the uplink data, the port of the NW-TT can be an input port of the data, and the port of the second DS-TT is an output port of the data. The terminal may be co-located with the DS-TT. User Plane Function (UPF) may be combined with NW-TT.

As shown in FIG. 1, a terminal may be connected to one or more DS-TT, and a DS-TT may have one or more ports. A 5G bridge may have a UPF that may enable one or more ports 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 combined by the UPF. The port of the DS-TT becomes a port of the 5G bridge. Both the port of the DS-TT and the port of the NW-TT can be connected separately, a TSN Bridge (TSN Bridge) and/or an End Station (End Station). Through the 5G bridges, TSN bridges and/or end stations to which ports of the TT are connected may communicate.

It should be noted that fig. 1 is only an exemplary schematic diagram, and 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.

In order to support the implementation of a bridge consisting of a terminal, a time-sensitive adapter and a wireless communication network, the following problems also need to be solved

Problem 1: as shown in the schematic diagram of FIG. 3, port 1 and port 2 are located on the same DS-TT. At this point, the "5GS Bridge delay per port paper per traffic class" does not contain PDB, and does not require the network to be assembled from PDB. This delay needs to be reported to the CNC by the AF of the 5G bridge. But currently such reporting is not supported.

Problem 2: as shown in the schematic diagram of FIG. 4, port 1 is the port on the first DS-TT; port 2 is the port of the second DS-TT. The first DS-TT and the second DS-TT may be different DS-TT in the same 5G bridge connecting the same UE. At this point, the "5GS Bridge delay per port paper per traffic class" does not contain PDB, and does not require the network to be assembled from PDB. This delay needs to be reported to the CNC by the AF of the 5G bridge. But currently such reporting is not supported.

Problem 3: as shown in the schematic diagram of FIG. 5, port 1 is the port on the first DS-TT; port 2 is the port of the second DS-TT. The first DS-TT and the second DS-TT may be different DS-TT connecting different UEs in the same 5G bridge. At this point, "5GS Bridge per port pair per traffic class delay (5 GS Bridge per port pair) should contain two segments of PDB and two segments of UE-DS-TT dwell Time (redundancy Time).

First, the PDB is different from the existing PDB. The existing PDB is the location where the N6 interface is to be terminated, while the PDB of problem 3 is the internal local switch (local switch) of the UPF, which may be a short latency with the existing PDB.

Secondly, the existing 5G bridge delay can be assembled by SMF, PCF or AF. However, the SMFs of the first UE and the second UE are different, and the PDB condition and the UE-DS-TT reliability time condition of the opposite side are not known respectively, so that the UE-DS-TT reliability time cannot be assembled.

Problem 4: as shown in the schematic diagram of fig. 6, when port 3 and port 4 are enabled as ports in the 5G bridge, there may not be port access on the DS-TT side concerned yet, i.e. there is no PDU session setup related to port 3 or port 4 yet, there is no SMF related to the UE yet, and there is no PCF associated with the PDU session of the UE yet. At this time, the information on the port pair consisting of port 3 and port 4 cannot be transmitted by the PDU session related signaling. It is not clear whether and how the information about the port pair of port 3 and port 4 is reported to the CNC.

Problem 5: as shown in the schematic diagram of fig. 6, when port 3 is enabled as a port in a 5G bridge, on one hand, there may not be a port access on the DS-TT side concerned, i.e. there is no PDU session setup related to port 3 yet, there is no SMF related to the UE yet, and there is no PCF associated with the PDU session of the UE yet. At this time, the related information of port 3 cannot be transmitted through the PDU session related signaling. It is not clear whether and how port 3 related information is reported to the CNC. On the other hand, when port 3 is enabled as a port in a 5G bridge, on one hand, there may be multiple port accesses on DS-TT side, i.e. there are multiple PDU sessions on port 3, and at this time, the related information of port 3 through which PDU session related signaling is still unclear.

In this embodiment of the present invention, optionally, obtaining may be understood as obtaining from configuration, receiving after a request, obtaining by self-learning, deriving and obtaining according to unreceived information, or obtaining according to received information after processing, which may be specifically determined according to actual needs, and this is not limited by this embodiment of the present invention. For example, when a certain capability indication sent by the device is not received, it can be deduced that the device does not support the capability.

Optionally, the sending may include broadcasting, broadcasting in a system message, and returning after responding to the request.

Alternatively, preconfigured may be referred to as default.

In an alternative embodiment of the present invention, the port control information container may also be referred to as a port management information container. The port control information container is a container for carrying port control information (also referred to as port management information).

In an optional embodiment of the present invention, the port related information includes: a port control information container. In an alternative embodiment of the present invention, the port-related information may be understood as any one or more pieces of information about a port managed by a bridge (e.g., port-related configuration information in bridge management in 802.1Q).

In an embodiment of the present invention, the port may be one of an ethernet port and an IP port.

In an alternative embodiment of the invention, the channel may include, but is not limited to, one of: PDU session, PDN connection, qoS flow, bearer, internet Protocol Security (IPsec) channel, where the Bearer may be an Evolved Radio Access Bearer (E-RAB), an Evolved Radio Access Bearer (RAB), a Data Radio Bearer (DRB), a Signaling Radio Bearer (SRB), and the like.

In an alternative embodiment of the present invention, the port pair is composed of two ports, for example: consisting of two ports of the same DS-TT, or of two ports of different DS-TT, or of two ports of the same NW-TT, or of two ports of different NW-TT.

The identification information such as DS-TT includes at least one of: MAC address of DS-TT, IP address of DS-TT. The identification information such as NW-TT includes at least one of: MAC address of NW-TT, IP address of NW-TT.

In an alternative embodiment of the present invention, the bridge delay of a port pair may refer to the time when a packet passes through another port from one port, and the two ports are two ports of the same bridge. It will be appreciated that bridge latency may be the time overhead for packets to pass through the bridge.

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

In an alternative embodiment of the present invention, the bridge delay of a port pair may be a per traffic class (per traffic class) bridge delay. Each port may support one or more traffic classes. The transmission performance of each traffic class is different, so it is not difficult to understand the bridge delay of the port pair of each traffic class of the output port. The bridge delay for each traffic class port pair may be different.

That is, the port bridge delay may also refer to the bridge delay of a certain traffic class, and of course, the bridge delays of different traffic classes may be the same or different.

In an alternative embodiment of the invention, the port of TT, the port on TT side and the port on TT side represent the same meaning and can be mixed.

In an alternative embodiment of the invention, the port associated lanes are typically associated with one DS-TT port and one NW-TT port. It is understood that the channel associated with the port of the DS-TT is the same channel as the channel associated with the port of the NW-TT. Through the establishment of the channel (such as PDU session), the port of the DS-TT is made a port of a bridge, or the port of the DS-TT and the port of the NW-TT are associated.

Example 1:

this embodiment may be applied to the scenarios shown in fig. 3 and 4, as shown in fig. 10, and may include the following:

step 1001: the first PDU session and/or the second PDU session is established. The first PDU session is an inter-UPF 1) Port 1 associated PDU session for the UE, 2) Port 3 associated PDU session the first PDU session is an inter-UPF 1) Port 2 associated PDU session for the UE, 2) Port 4 associated PDU session

Port 1 is a port on the first DS-TT, port 2 is a port on the second DS-TT, and ports 3 and 4 are ports on the NW-TT. The first DS-TT and the second DS-TT may be the same DS-TT or different DS-TT.

Step 1002: the UE obtains the bridge delay of the first port pair. The first port pair consists of port 1 and port 2. The bridge latency of the first port pair is traffic class (per traffic class). That is, each traffic class supported by a port pair has a bridge delay of the first port pair, and the bridge delay of the first port pair of each traffic class may be different. Port 1 is a port on the first DS-TT; port 2 is the port on the second DS-TT.

In one embodiment, the DS-TT sends the bridge delay of the first port pair to the UE or the UE obtains the bridge delay of the first port pair from the DS-TT. For example, when port 1 and port 2 of the first port pair are ports on the same DS-TT, the UE obtains the bridge delay of the first port pair from the DS-TT. For example, when port 1 and port 2 of the first port pair are ports on different DS-TTs, the first DS-TT or the second DS-TT may measure and/or calculate the bridge delay to acquire the first port pair. At this time, the UE may also obtain the bridge delay of the first port pair from the first DS-TT or the second DS-TT.

In another embodiment, the UE measures and/or calculates a bridge delay to acquire the first port pair. For example, when port 1 and port 2 of the first port pair are different ports on DS-TT, the UE measures and/or calculates the bridge delay for obtaining the first port pair.

The UE selects the first PDU session or the second PDU session, and sends bridge-related information of the first port pair to the network through related signaling (e.g., PDU session modification request) of the first PDU session or related signaling (e.g., PDU session modification request) of the second PDU session (as described in the embodiment of fig. 2).

In one embodiment, the bridge latency of the first port pair is sent to the AF in a port control information container. The port control information container is included in signaling associated with the first PDU session or signaling associated with the second PDU session.

In one embodiment, the bridge latency of the first port pair is sent to the SMF outside the port control information container. The SMF sends the bridge delay of the first port pair to the AF through the PCF.

Step 1003: and the AMF sends a PDU session _ update session management context request to the SMF, wherein the PDU session _ update session management context request comprises the PDU session modification request.

Step 1004: optionally, the SMF sends an N4 session modification request to the UPF.

Step 1005: optionally, the UPF sends an N4 session modification response to the SMF. In one embodiment, the UPF may include bridge related information for the second port pair on the NW-TT side in the N4 session modification response (as described in the embodiment of fig. 2).

The second port pair consists of port 3 and port 4. The bridge latency of the second port pair is traffic class (per traffic class). I.e. each traffic class supported by a port pair has a bridge delay of the second port pair, the bridge delay of the second port pair of each traffic class may be different. Ports 3 and 4 are ports on the NW-TT.

In one embodiment, the bridge delay of the second port pair is contained in a port control information container sent to the AF. The port control information container is included in signaling associated with the first PDU session or signaling associated with the second PDU session.

In one embodiment, the bridge latency of the second port pair is sent to the SMF outside the port control information container. The SMF sends the bridge delay of the first port pair to the AF through the PCF.

Step 1006: the SMF sends a SMF trigger session management policy association modification request to the PCF. The SMF trigger session management policy association modification request comprises bridge related information of the first port pair and/or bridge related information of the second port pair.

Step 1007: the PCF sends an event notification to the AF. The event notification comprises bridge-related information of the first port pair and/or bridge-related information of the second port pair.

After receiving the bridge-related information of the first port pair and/or the bridge-related information of the second port pair, the AF sends the bridge-related information of the first port pair and/or the bridge-related information of the second port pair to a time-sensitive network control node (e.g., CNC).

The CNC determines scheduling control of the time sensitive data and configuration information of the bridge ports based on the bridge-related information of the first port pair and/or the bridge-related information of the second port pair.

Step 1008: the AF sends an event notification response to the PCF. Optionally, the event notification response contains configuration information of the bridge port.

Step 1009: the PCF sends an SMF trigger session management policy association modification request response to the SMF.

Step 1010: the SMF sends a PDU session _ update session management context response to the AMF. Optionally, the PDU session modification accept includes configuration information of a bridge port. .

Step 1011: and the AMF sends an NAS message to the UE, wherein the NAS message contains the PDU session modification.

The number of DS-TT can be used to distinguish different DS-TT, such as the port associated with the DS-TT with port number 1 and the DS-TT with port number 2 belonging to different DS-TT.

Step 2: when the SMF sends the information related to the port to the PCF, the TT related information of the TT related to the port, the PDB of each service class of the UE (PDB of per UE per traffic class), and the UE-DS-TT residual time of each service class of each port (UE-DS-TT residual time of per port per traffic class) are indicated. Wherein, the UE-DS-TT responsiveness time may be a port-to-terminal processing time.

And step 3: PCF sends port pair bridge time delay to AF, TT related information indicating port associated TT, PDB of each service class of UE (PDB of per UE per traffic class), and UE-DS-TT reliability time of each service class of each port (UE-DS-TT reliability time of per port per traffic class). Wherein, the UE-DS-TT responsiveness time may be a processing time between port 1 and the terminal.

The AF may determine, according to the UE associated with the port and the information about the TT where the port is located, one of the following:

whether the two ports of a port pair belong to the same DS-TT,

whether DS-TT where two ports of the port pair are located is associated with the same UE

Whether the two ports of a port pair belong to the same NW-TT.

Generating a bridge delay for the first port pair when the first condition is satisfied, in one embodiment, the bridge delay for the port pair may be the first UE-DS-TT responsiveness time + the second UE-DS-TT responsiveness time;

the first port and the second port of the port pair belong to different DS-TT;

the DS-TT of the first port and the DS-TT of the second port are connected to the same UE.

When the second condition is satisfied, generating a bridge delay of the first port pair, in one embodiment, the bridge delay of the port pair may be the first UE-DS-TT responsiveness time + the PDB of the first UE + the second UE-DS-TT responsiveness time + the PDB of the second UE; in another embodiment, the bridge delay of the port pair may be the bridge delay of the port pair of port 1 and end 3 + the bridge delay of the port pair of port 1 and end 3;

the first port and the second port of the port pair belong to different DS-TT

The DS-TT of the first port and the DS-TT of the second port are connected with different UEs.

Example 3:

this embodiment may be applied to the scenario shown in fig. 6, and as shown in fig. 11, may include the following:

step 1101: optionally, the first PDU session and/or the second PDU session is established. The first PDU session is an inter-UPF 1) Port 1 associated PDU session for the UE, 2) Port 3 associated PDU session the first PDU session is an inter-UPF 1) Port 2 associated PDU session for the UE, 2) Port 4 associated PDU session

Port 1 is a port on a first DS-TT, port 2 is a port on a second DS-TT, and ports 3 and 4 are ports on a NW-TT. The first DS-TT and the second DS-TT may be the same DS-TT or different DS-TT.

Step 1102: the UPF obtains the bridge delay of the first port pair. The two ports in the first port pair are the ports on the NW-TT (port 3 and port 4). The bridge delay is per traffic class

The UPF selects a SMF to transmit the bridge delay of the first port pair. When a first PDU session and/or a second PDU session exist, selecting the SMF of the first PDU session or the second PDU session. Otherwise, a preconfigured SMF is selected. UPF may send bridge delay for the first port pair via N4 report message

The UPF sends an N4 report request to the selected SMF, wherein the N4 report request comprises the bridge related information of the first port.

Step 1103: if the SMF is a pre-configured SMF, the SMF selects a pre-configured PCF.

The SMF sends an SMF trigger session management policy association modification request to the PCF. The SMF trigger session management policy association modification request contains bridge related information of the first port pair.

Step 1104: the PCF sends an event notification to the AF. The event notification contains bridge-related information for the first port pair.

After receiving the bridge related information of the first port pair, the AF sends the bridge related information of the first port pair to a time-sensitive network control node (e.g., CNC).

And 4, step 4: and the PCF sends the bridge delay of the first port pair to the AF.

And 5: the AF reports the bridge delay of the first port pair to the CNC.

when two ports in a port pair are both ports on the same DS-TT, the UE reports the bridge delay of the port pair to the network;

when two ports in a port pair are ports on different DS-TT and the two DS-TT are connected with the same UE, the UE reports the bridge delay of the port pair to the network or the UE assists the network to calculate the bridge delay of the port pair. Informing the relevant information of DS-TT of the port, such as PDU session establishment of the port;

when two ports in a port pair are ports on different DS-TT and the two DS-TT are connected with different UE, the network is required to specially calculate the bridge delay of the port pair;

when two ports in a port pair are ports on different NW-TT, if PDU session of DS-TT port is not established, bridge delay of the port pair needs to be sent to AF through the pre-configured SMF and the pre-configured PCF.
