[0106] The inventors noticed during the invention process that:

[0107] Figure 1 The following is a schematic diagram of the 5G network architecture. As shown in the figure, the currently determined 5G network architecture contains end-to-end nodes or network elements, including:

[0108] UE (User Equipment): 5G terminal equipment;

[0109] (R)AN (Radio Access Network): access network equipment;

[0110] UPF (User plane Function) equipment;

[0111] The 5G control plane adopts a service-based architecture. The control plane network elements include AUSF (Authentication Server Function), AMF (Mobility Management Function), SMF (Session Management Function), NSSF (Network Slice Selection Function), NEF (Network Exposure Function), NRF (Network Repository Function), PCF (Policy Control Function), UDM (Unified Data Management) and AF (Application Function).

[0112] UDM completes functions such as user contract data management, authentication information generation, mobility management, and short message routing;

[0113] AUSF provides authentication related functions.

[0114] Figure 2 This is a schematic diagram of the 5G user plane protocol stack. The protocol stack between the 5G user plane UE-RAN-UPF is as follows Figure 2 As shown, where:

[0115] PDU (Packet Data Unit) layer: This layer corresponds to the PDU carried between the UE and the DN (Data Network) in the PDU session. When the PDU session type is IPv4 (Internet Protocol Version 4) or IPv6 (Internet Protocol Version 6) or IPv4v6, it corresponds to IPv4 data packets or IPv6 data packets or both; when the PDU session type is Ethernet, it corresponds to Ethernet frames.

[0116] TAN (Time Aware Network) technology is a new time-based industrial communication technology. Figure 3 The schematic diagram of the TAN frame structure is shown in Figure 2. The clock synchronization technology is introduced into the TAN system and the TAN frame header is encapsulated before the standard Ethernet frame header field (such as Figure 3As shown in the figure, the destination switch, source switch, data priority, data sequence number, and various time identifiers of the data are used to process the data. Because TAN technology encapsulates standard Ethernet frames, it has good compatibility with various industrial protocols used in current industrial networks. Based on the observability of TAN, the network can know the source, purpose, content, and time of the data. At present, TAN technology has been well applied in many fields of the industrial Internet, such as synchronous transmission of control instructions, redundant data backup, and data monitoring.

[0117] Figure 4 The following is a schematic diagram of the integration of TAN system and wireless network. The architecture of TAN and 5G integration is as follows Figure 4 As shown in the figure, most of the control information of the TAN system is transmitted between TAN switches through the TAN header field. The TAN switch distinguishes and schedules data based on its own algorithm and the TAN header field. However, in the scenario of wireless deployment, when TAN is integrated with the 5G network, when the TAN frame is transmitted in the 5G network, the current implementation mechanism is to encapsulate the TAN frame in an IP data packet for transmission ( Figure 5 Schematic diagram of IP encapsulation of TAN data pair Figure 1 ,like Figure 5 As shown in Figure 1). The QoS (Quality of Service) rules of the 5G network only perform QoS control on IP packets based on the IP packet filter set in the IP packet header. The TAN header field does not play any role as the content data information in the IP packets transmitted in the 5G system. Under this architecture, the 5G end-to-end (UE-UPF) network only serves as a data transparent transmission line between TAN switches, and implements best-effort transmission for the transmission path between TAN switch devices. TAN currently has no mechanism to enable the operator network to adapt to the transmission requirements of its system.

[0118] The encapsulation format of TAN data in IP data packet is shown in Figure 5.

[0119] Among them, there is currently a plan to define the IP Packet Filter Set for QoS control in 5G, which includes the following items:

[0120] -Source / destination IP address or IPv6 prefix.

[0121] -Source / destination port number.

[0122] -Protocol ID of the protocol above IP / Next header type.

[0123] -Type of Service (TOS) (IPv4) / Traffic class (IPv6) and Mask.

[0124] -Flow Label(IPv6).

[0125] -Security parameter index.

[0126] -Packet Filter direction. (Packet filter direction)

[0127] This solution has not been used in actual deployment, but some solutions also define Ethernet session types. If Ethernet type sessions are used to transmit TAN packets, Figure 6 Schematic diagram of IP encapsulation of TAN data pair Figure 2 , its packaging format is as follows Figure 6 As shown in the figure, like IP type sessions, the QoS rules of the 5G network only perform QoS control on Ethernet packets based on the Ethernet Packet Filter Set (Ethernet Packet Filter Set) in the Ethernet packet header. The TAN header field does not play any role as the content data information in the Ethernet packets transmitted in the 5G system.

[0128] The Ethernet Packet Filter Set used by 5G for QoS control includes the following items:

[0129] -Source / destination MAC address. (MAC: Media Access Control)

[0130] -Ethertype as defined in IEEE 802.3.

[0131] -Customer-VLAN tag (C-TAG) and / or Service-VLAN tag (S-TAG) VID fields as defined in IEEE Std 802.1Q

[98] . (Customer VLAN tag (C-tag) and / or Service VLAN tag (S-tag) VID fields as defined in IEEE Std 802.1Q

[98] ; VLAN: Virtual Local Area Network)

[0132] -Customer-VLAN tag (C-TAG) and / or Service-VLAN tag (S-TAG) PCP / DEI fields as defined in IEEE Std 802.1Q

[98] . (Customer VLAN tag (C-tag) and / or Service VLAN tag (S-tag) PCP / DEI fields as defined in IEEE Std 802.1Q

[98] )

[0133] -IP Packet Filter Set, in the case that Ethertype indicates IPv4 / IPv6 payload. (If Ethertype indicates IPv4 / IPv6 payload, set IP packet filter)

[0134] -Packet Filter direction.

[0135] Based on this, the technical solution provided in the embodiment of the present invention proposes a fusion architecture of the two systems, and promotes better integration of the two systems by adding a TAN system control center in the system architecture to realize the identification of the business flows of the two systems, the interaction of business quality requirements, the adaptation of policies, and the mapping of data packets, so that the currently supported 5G systems for IP data packet transmission and Ethernet data packet transmission can be well adapted to the transmission quality requirements of the TAN system, rather than just serving as a data transmission line between TAN switches, thereby achieving better integration of the two systems, that is, utilizing the convenience of wireless deployment brought by wireless networks and realizing the high-reliability deterministic delay transmission guarantee provided by the TAN system.

[0136] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0137] In the process of explanation, the implementation will be explained from the perspectives of UE, TAN system control center side, and PCF side, and SMF will also be involved. This explanation does not mean that they must be implemented in coordination or separately. In fact, when they are implemented separately, they also solve the problems on their own side, and when they are used in combination, better technical effects will be obtained.

[0143] Step 801: A TAN system control center receives 5G session related information sent by a UE, wherein the TAN system control center is a functional body that determines service requirements and service flow identification information;

[0144] Step 802: The TAN system control center determines the service requirements and service flow identification information based on the service transmission quality requirements, the control information of the TAN system and the 5G session related information. The service requirements and service flow identification information are used to generate data QoS rules encapsulated in a predetermined format and sent to the UE for transmission encapsulated in an IP message or Ethernet frame.

[0145] Fig. 9 A schematic diagram of the implementation process of the rule generation method on the PCF side is shown in the figure, which may include:

[0146] Step 901: The PCF generates a PCC Rule, where the PCC Rule is used for the UE to perform QFI mapping according to the QoS Rule.

[0147] Step 902: The PCF sends the PCC Rule to the SMF.

[0148] In the technical solution provided by the embodiment of the present invention, a TAN system control center is added to the system architecture to realize the identification of the service flows of the two systems, the interaction of service quality requirements, the adaptation of policies, and the mapping of data packets, thereby promoting better integration of the two systems.

[0183] During implementation, the service data flow filter data packet identification information included in the QoS Rule includes the UE source address and TAN header field information.

[0184] Specifically, the PCF generates a PCC Rule and sends it to the SMF (wherein the service data flowfilter (service data flow filter) data packet identification information included in the rule includes the UE source address, TAN header field information, etc.).

[0185] The following is an example to illustrate.

[0186] Embodiment 1:

[0187] In this example, the UE establishes the same IP or Ethernet type session for TAN data, and uses different QoS to distinguish data types based on the IP header field or Ethernet header field mapped by the TAN header field.

[0188] Fig.10 This is a schematic diagram of the TAN system and 5G network integration solution 1. The TAN system and 5G network solution are as follows Fig.10 As shown, the UE establishes the same IP or Ethernet type session for TAN data exchanged between the same source TAN switch and the destination TAN switch, and encapsulates the received TAN data in the payload of the IP message or Ethernet frame. The field indicating the data type or data priority in the TAN header field is mapped to the type of service or traffic class type in the IP header field or the VLAN tag in the MAC header field of the Ethernet frame. Different TAN data types are distinguished by the IP header field or Ethernet header field mapped by the TAN header field to use different QoS to provide transmission guarantee for them.

[0189] The TAN system control center collects service information, TAN switch control information, and 5G session-related information, and generates service transmission requirements for different data flows and flow identification information Flow description(s). Flow description(s) is used to distinguish different TAN data types encapsulated into IP packets or Ethernet frames.

[0190] The TAN system control center sends the service requirements to the 3GPP PCF policy charging function, generates PCC (Policy and Charging Control) rules through PCF (Policy Control Function), and returns them to UE, RAN, and UPF by SMF to implement different QoS controls for different TAN data types.

[0191] Fig.11 A schematic diagram of the implementation process of the TAN system and 5G network integration solution 1 is shown in the figure, which may include:

[0192] Step 1100: UE receives TAN data and triggers a session establishment request;

[0193] Step 1101: Session establishment process: the network allocates an IP address to the UE requesting an IP session;

[0194] Step 1102: The UE encapsulates the received TAN data in the payload of the IP message or Ethernet frame. The field indicating the data type or data priority in the TAN header field is mapped to the type of service or traffic classtype in the IP header field or the VLAN tag in the MAC header field of the Ethernet frame.

[0195] Step 1103: The UE sends information related to the 5G session to the TAN system control center, including the UE source address (UE IP address or UE MAC address), and the type of service / trafficclass type in the IP header field after mapping with the TAN header field information, or the VLAN tag information in the Ethernet frame MAC header field;

[0196] Step 1104: The TAN system control center determines the service requirements and service flow identification information (such as UE source address, IP header field or MAC header field mapped with TAN header field information, etc.) based on the service transmission quality requirements, the control information of the TAN system and the 5G session related information;

[0197] Step 1105: Send service quality requirements of different data to PCF (Flow description(s) includes UE source address, IP header field or MAC header field mapped with TAN header field information, etc.)

[0198] Step 1106: PCF generates a PCC Rule and sends it to SMF (the service data flow filter packet identification information includes the UE source address, type of service / traffic class type in the IP header field or the VLAN tag in the MAC header field, etc.)

[0199] Step 1107a, SMF sends QoS Rule to UE (Packet Filter includes UE IP address, type of service / traffic class type in IP header or VLAN tag in MAC header, etc.)

[0200] Step 1107b: SMF sends QoS Profile to RAN.

[0201] Step 1107c, SMF sends UL / DL PDR to UPF (SDF template includes UE source address, type of service / traffic class type in IP header or VLAN tag in MAC header, etc.);

[0202] Step 1108: Use the new QoS rule to transmit the TAN data encapsulated in the IP message or Ethernet frame.

[0203] Among them, in step 1102, Fig.12The diagram of the mapping between the IP header field and the TAN header field is shown in the figure. The field indicating the data type or data priority in the TAN header field is mapped to the type of service / traffic class type in the IP header field. The channel protocol field in the TAN header field is mapped to the type of service / traffic classtype in the IP header field. The specific mapping method is as follows:

[0204] For the field representing higher priority control information in the TAN header field, it is mapped to the 8-bit type of service of IPv4. The first 3 bits represent the priority of the packet in PPP, which can be 010 for immediate transmission (Immediate), 011 for lightning transmission (Flash), 100 for flash override, etc. The larger the value, the more important the data. The mapping of the last 5 bits DTRCO can be D delay is 1 (0: normal, 1: delay is as small as possible), T throughput is 1 (0: normal, 1: traffic is as large as possible), R reliability is 1 (0: normal, 1: reliability is as large as possible), M transmission cost is 0 (0: normal, 1: cost is as small as possible), and the last bit is reserved as 0.

[0205] For the fields in the TAN header field that represent lower priority information such as ordinary data information, they are mapped to the 8-bit typeof service of IPv4. The first 3 bits of PPP that represent the priority of the packet can be 000 ordinary (Routine). The larger the value, the more important the data is. The mapping of the last 5 bits DTRCO can be D delay is 0 (0: ordinary, 1: delay is as small as possible), T throughput is 0 (0: ordinary, 1: traffic is as large as possible), R reliability is 0 (0: ordinary, 1: reliability is as large as possible), M transmission cost is 1 (0: ordinary, 1: cost is as small as possible), and the last bit is retained and kept constant at 0.

[0206] Fig.13 The diagram of the mapping between the MAC header and the TAN header shows how the field indicating the data type or data priority in the TAN header is mapped to the tag in the MAC header of the Ethernet frame. Fig.13 As shown, the channel protocol field in the TAN header field is mapped to the Tag in the MAC frame header field.

[0207] For example, the field representing higher priority control information in the TAN header is mapped to the 3-bit PCP field representing the priority of the Tag in the MAC frame header, or a virtual 12-bit VLAN ID field is constructed that is agreed upon by various entities in the 5G network.

[0208] The field representing the higher priority control information in the TAN header is mapped to the 3-bit PCP field of the Tag in the MAC frame header, which is 7, or 0x001 representing the high-priority virtual VLAN ID.

[0209] The field representing the higher priority control information in the TAN header is mapped to the 3-bit PCP field of the Tag in the MAC frame header, which is 3, or 0x002 representing the high priority virtual VLAN ID.

[0210] Embodiment 2:

[0211] In this example, the UE establishes the same IP or Ethernet type session for TAN data, and uses different QoS to distinguish data types through the combination of IP header field and TAN header field.

[0212] Fig.14 This is a schematic diagram of TAN system and 5G network integration solution 2. The specific implementation content is shown in the figure, and you can also refer to the description in Example 1.

[0213] Fig.15 The implementation process diagram of TAN system and 5G network integration solution 2 is as shown in the figure, which can be as follows:

[0214] Step 1500: UE receives TAN data and triggers a session establishment request;

[0215] Step 1501: Session establishment process: the network allocates an IP address to the UE requesting an IP session;

[0216] Step 1502: The UE sends information related to the 5G session to the TAN system control center, including the UE source address (UE IP address or UE MAC address), TAN header information, etc.

[0217] Step 1503: The TAN system control center determines the service requirements and service flow identification information (such as UE source address, TAN header information, etc.) based on the service transmission quality requirements, the control information of the TAN system and the 5G session related information;

[0218] Step 1504: Send service quality requirements of different data to PCF (Flow description(s) including UE source address, TAN header information, etc.);

[0219] Step 1505: PCF generates a PCC Rule and sends it to SMF (the service data flow filter packet identification information includes the UE source address, TAN header field information, etc.);

[0220] Step 1506a, SMF sends QoS Rule (Packet Filter including UE IP address, TAN header information, etc.) to UE, and instructs UE to perform QFI mapping according to Packet Filter;

[0221] Step 1506b: SMF sends QoS Profile to RAN.

[0222] Step 1506c, SMF sends UL / DL PDR (uplink / downlink PDR; PDR: Packet Detection Rule) (SDF template (SDF template; SDF: Service Data Flow) including UE source address, TAN header information, etc.) to UPF, and instructs UPF to perform QFI mapping according to the SDF template;

[0223] Step 1507: Use the new QoS rule to transmit the TAN data encapsulated in the IP message or Ethernet frame.

[0224] Among them, the service data flow filter, PacketFilter, and SDF template involved in steps 1505, 1506a, and 1506c are used for the IP Packet Filter Set for QoS control, and the project includes adding a field indicating the data type or data priority in the TAN frame header, such as the channel protocol field in the TAN frame header:

[0225] -Source / destination IP address or IPv6 prefix.

[0226] -Source / destination port number.

[0227] -Protocol ID of the protocol above IP / Next header type.

[0228] -Type of Service(TOS)(IPv4) / Traffic class(IPv6)and Mask.

[0229] -Flow Label (IPv6).

[0230] -Security parameter index.

[0231] -Packet Filter direction.

[0232] - A field in the TAN frame header indicating the data type or data priority (eg, the channel protocol field in the TAN frame header).

[0233] The Ethernet Packet Filter Set used for QoS control contains the following items:

[0234] -Source / destination MAC address.

[0235] -Ethertype as defined in IEEE 802.3.

[0236] -Customer-VLAN tag(C-TAG)and / or Service-VLAN tag(S-TAG)VID fields asdefined in IEEE Std 802.1Q

[98] .

[0237] -Customer-VLAN tag(C-TAG)and / or Service-VLAN tag(S-TAG)PCP / DEI fieldsas defined in IEEE Std 802.1Q

[98] .

[0238] -IP Packet Filter Set,in the case that Ethertype indicates IPv4 / IPv6payload.

[0239] -Packet Filter direction.

[0240] - A field in the TAN frame header indicating the data type or data priority (eg, the channel protocol field in the TAN frame header).

[0245] Step 1700: The UE receives TAN data and triggers different session establishment requests according to different TAN data types. If it is an Ethernet session, the UE needs to construct different virtual MAC addresses for different sessions to distinguish different types of TAN data transmitted on different sessions.

[0246] Step 1701: Session establishment process: the network allocates an IP address to the UE requesting an IP session.

[0247] Step 1702: The UE sends information related to the 5G session to the TAN system control center, including the UE source address (UE IP address or UE virtual MAC address), etc.

[0248] Step 1703: The TAN system control center determines the service requirements and service flow identification information (such as UE source address (UE IP address or UE virtual MAC address) etc.) based on the service transmission quality requirements, the control information of the TAN system and the 5G session related information;

[0249] Step 1704: Send service quality requirements of different data to PCF (Flow description(s) including UE source address, etc.);

[0250] Step 1705: PCF generates a PCC Rule and sends it to SMF (the service data flow filter data packet identification information includes the UE source address, etc.);

[0251] Step 1706a, SMF sends QoS Rule (Packet Filter including UE IP address, etc.) to UE, and instructs UE to perform QFI mapping according to Packet Filter;

[0252] Step 1706b: SMF sends QoS Profile to RAN.

[0253] Step 1706c, SMF sends UL / DL PDR (SDF template includes UE source address, etc.) to UPF, and instructs UPF to perform QFI mapping according to the SDF template;

[0254] Step 1707: Use the new QoS rule to transmit the TAN data encapsulated in the IP message or Ethernet frame.
