Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In addition, the use of "and/or" in the description and the claims indicates at least one of the connected objects, such as A and/or B, indicating that there are three cases including A alone, B alone, and both A and B.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as an example, illustration or illustration. Any embodiments or designs described as "exemplary" or "such as" in the embodiments of the present invention should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present the related concepts in a specific manner.

Embodiments of the present invention will be described below with reference to the accompanying drawings. The information transmission method and the communication device provided by the embodiments of the present invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, or an Evolved Long Term Evolution (Evolved Long Term Evolution, eLTE for short) system, or a subsequent evolved communication system.

In this 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 streams can also be referred to as periodic deterministic data streams. A time-sensitive network technology such as IEEE TSN (Time Sensing Network). Periodic deterministic communication is to transmit data periodically at the transmission interval.

Referring to FIG. 1 , it is a schematic structural diagram of an applicable wireless communication system according to an embodiment of the present invention. In this embodiment of the present invention, the sender of the time-sensitive data stream may be referred to as a talker, and the receiver of the time-sensitive data stream may be referred to as a listener. One or more bridges that can pass between the talker and the listener forward data. The end station node (End Station) can be a talker or a listener. Bridge (Bridge) is responsible for data transfer between talker and listener.

Terminals (such as User Equipment, UE), time-sensitive adapters, and wireless communication networks form a bridge (the 5G bridge will be used as an example to illustrate later). For downlink data, the port of the device-side time-sensitive network adapter (DS-TT) can be the outgoing port of data, and the port of the network-side time-sensitive network adapter (NW-TT) is the ingress port of data. For uplink data, the port of the NW-TT may be the ingress port of the data, and the port of the second DS-TT may be the egress port of the data. The terminal can be co-located with DS-TT. User Plane Function (UPF) can be co-configured with NW-TT.

As shown in Figure 1, a terminal can be connected to one or more DS-TTs, and one 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 of the port of the DS-TT, and establish a protocol data unit (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 co-located by the UPF. Said port of DS-TT becomes a port of the 5G bridge. Both the DS-TT port and the NW-TT port can be connected separately, TSN Bridge (TSN Bridge) and/or End Station (End Station). Through the 5G bridge, the TSN bridge and/or the terminal station connected to the port of the TT can communicate.

It should be noted that FIG. 1 is only a schematic diagram of an example. In the embodiment of the present invention, the structure of the 5G network bridge and the connection relationship between ports in the 5G network bridge are not limited.

In order to support the realization of the bridge composed of terminal, time-sensitive adapter and wireless communication network, the following problems need to be solved

Question 1: As shown in the schematic diagram of Figure 3, port 1 and port 2 are located in the same DS-TT. At this time, "5GS Bridgedelay per port pair per traffic class" does not include the PDB, and the network does not need to be assembled according to the PDB. This delay needs to be reported to the CNC through the AF of the 5G bridge. However, such reporting is not currently supported.

Question 2: As shown in the schematic diagram of Figure 4, port 1 is the port on the first DS-TT; port 2 is the port on the second DS-TT. The first DS-TT and the second DS-TT may be different DS-TTs connected to the same UE in the same 5G bridge. At this time, "5GSBridge delay per port pair per traffic class" does not include PDB, and the network does not need to be assembled according to PDB. This delay needs to be reported to the CNC through the AF of the 5G bridge. However, such reporting is not currently supported.

Question 3: As shown in the schematic diagram of Figure 5, port 1 is the port on the first DS-TT; port 2 is the port on the second DS-TT. The first DS-TT and the second DS-TT may be different DS-TTs connected to different UEs in the same 5G bridge. At this time, "5GS Bridge delay per port pair per traffic class" should include two sections of PDB and two sections of UE-DS-TT residence time (Residence Time).

First, the PDB is not the same as the existing PDB. The existing PDB is the location where the N6 interface is to be terminated, and the PDB in question 3 is the internal local switch of the UPF, which may have a shorter delay than the existing PDB.

Second, the existing 5G bridge delay can be assembled and generated by SMF, PCF or AF. However, the SMFs of the first UE and the second UE are different, and they do not know the PDB situation and the UE-DS-TT residence time situation of the other party respectively, so they cannot be assembled.

Question 4: As shown in the schematic diagram in Figure 6, when ports 3 and 4 are enabled as ports in the 5G bridge, there may be no related port access on the DS-TT side, that is, there is no PDU about port 3 or port 4. The session is established, there is no SMF associated with the UE yet, and there is no PCF associated with the UE's PDU session. At this time, the related information of the port pair formed by the port 3 and the port 4 cannot be sent through the PDU session related signaling. Then, it is unclear whether and how to report the relevant information of the port pair formed by port 3 and port 4 to the CNC.

Question 5: As shown in the schematic diagram in Figure 6, when port 3 is enabled as a port in a 5G bridge, on the one hand, there may be no related port access on the DS-TT side, that is, no PDU session on port 3 has been established. There is no SMF associated with the UE yet, nor PCF associated with the UE's PDU session. At this time, the related information of port 3 cannot be sent through PDU session related signaling. Then it is unclear whether and how to report the relevant information of port 3 to the CNC. On the other hand, when port 3 is enabled as a port in a 5G bridge, on the one hand, there may be multiple port accesses on the DS-TT side, that is, there are multiple PDU sessions on port 3, which PDU session is passed through at this time. The relevant information of the relevant signaling sending port 3 is still unclear.

In this embodiment of the present invention, optionally, obtaining may be understood as obtaining from configuration, receiving, receiving after request, obtaining through self-learning, deriving and obtaining according to unreceived information, or obtaining after processing according to received information.

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

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

In an optional embodiment of the present invention, the identification information of the TT includes at least one of the following: the MAC address of the TT, and the IP address of the TT. For example, the identification information of the DS-TT includes at least one of the following items: the MAC address of the DS-TT, and the IP address of the DS-TT. For example, the identification information of the NW-TT includes at least one of the following items: the MAC address of the NW-TT, and the IP address of the NW-TT.

In an optional embodiment of the present invention, the bridge delay of a port pair may refer to the time taken for a data packet to pass from one port to another port, and the two ports are two ports of the same network bridge. It is not difficult to understand that the bridge delay can be the time overhead of data packets passing 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 data packet to pass through the second port from the first port.

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

That is to say, the port bridge 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.

In an optional embodiment of the present invention, the port of the TT, the port on the TT, the port on the TT side, and the port on the TT side represent the same meaning and may be used in combination.

In an optional embodiment of the present invention, a channel associated with a port is generally associated with a DS-TT port and an NW-TT port. It is not difficult to understand that, at this time, the channel associated with the port of the DS-TT and the channel associated with the port of the NW-TT are the same channel. Through the establishment of the channel (eg, a PDU session), the DS-TT port becomes a port of the bridge, or the DS-TT port is associated with the NW-TT port.

In an 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 and obtain the bridge delay of the first port pair. At this time, the UE may also acquire the bridge delay of the first port pair from the first DS-TT or the second DS-TT.

For example, the ports associated with the TT number 1 of the DS-TT where the port is located and the TT number 2 of the DS-TT where the port is located belong to different DS-TTs.

Step 2: When the SMF sends the related information of the port to the PCF, it indicates the TT related information of the TT associated with the port, the PDB of each service class of the UE (PDB per UE per traffic class), and the PDB of each service class of each port.

Step 1102: The UPF obtains the bridge delay of the first port pair. The two ports in the first port pair are ports on the NW-TT (port 3 and port 4). The bridge delay is the bridge delay at which the UPF of the per traffic class selects an SMF to send the first port pair. When there is a first PDU session and/or a second PDU session, the SMF of the first PDU session or the second PDU session is selected. Otherwise, select a preconfigured SMF. UPF can send the bridge delay of the first port pair through the N4 report message

The UPF sends an N4 report request to the selected SMF, where the N4 report request includes the bridge-related information of the first port.

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

When both ports in the port pair are 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-TTs and the two DS-TTs are connected to 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 port pair's Bridge delay. For example, when the PDU session about the port is established, the relevant information of the DS-TT of the port is notified;

When two ports in a port pair are ports on different DS-TTs and the two DS-TTs are connected to different UEs, the network needs to specially calculate the bridge delay of the port pair;

When the two ports in the port pair are ports on different NW-TTs, if the PDU session of the DS-TT port has not been established, the port pair needs to be sent to the AF through the preconfigured SMF and the preconfigured PCF. Bridge delay.
