[0002] The purpose of 5G network slicing is to create dedicated virtual networks for different industries or enterprises on the operator's 5G network to meet the specialized needs of these industries or enterprises. Currently, the end-to-end definition of 5G network slicing is from user equipment (UE) to the core network. Therefore, the radio access network (RAN), transport network (TN), and core network (CN) all have corresponding slice perception and management mechanisms, and can guarantee the quality requirements of the slice's service-level agreement (SLA) in their respective network domains.

[0092] In embodiments of the present invention, the term "and / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0093] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0094] 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 only part of the embodiments of this application, not all of the embodiments. 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.

[0095] See also Figure 1 , Figure 1 This is a flow chart of a message processing method provided by an embodiment of the present invention, which is applied to UPF. Figure 1 As shown, the following steps are included:

[0096] Step 101: Send a first IP packet to a forwarding device of an IP bearer network, wherein the first IP packet carries information about a network slice.

[0097] In an embodiment of the present invention, the network slice information includes S-NSSAI. The network slice information (such as S-NSSAI) is encapsulated into an IP message for slice perception of the IP bearer network.

[0098] The network can support the selection of network slices based on S-NSSAI. S-NSSAI can identify a specific network slice and is not repeated within the PLMN (Public Land Mobile Network). Its format is as follows Figure 2 As shown, it includes SST and SD, a total of 32 bits, of which:

[0099] SST (Slice / Service type): indicates the slice / service type, 8 bits, 0-255. 0-127 are standard definitions, and 128-255 can be customized by operators.

[0100] SD (Slice Differentiator): indicates the slice differentiator, 24 bits, operator-defined.

[0101] Based on the network-wide uniqueness of S-NSSAI information, encapsulating it in IP packets can enable the IP bearer network to have the ability to accurately perceive network slicing services.

[0102] In this embodiment of the present invention, end-to-end services can be provided by an IPv4 bearer network or an IPv6 bearer network as needed. Accordingly, the first IP packet can include both an IPv4 packet and an IPv6 packet. In practical applications, each IPv4 packet and IPv6 packet is extended to enable them to carry S-NSSAI.

[0103] 1. Specific method of extending the IPv4 message: The S-NSSAI is carried in the option field of the IPv4 message. Specifically, the network slicing information is encapsulated through the option field of the message header.

[0104] In an embodiment of the present invention, the option field of the IPv4 message includes a slice ID option, and the slice ID option includes: option type, option length, and option data.

[0105] Specifically, such as Figure 3 As shown in the figure, the IPv4 packet header uses the "option field" to define a new option type and add the slice ID to the packet. The "slice ID option" is defined as follows:

[0106] Option Type = 221 (1101 1101):

[0107] Flag=1 (1 bit, option is copied to the fragment);

[0108] Class=2 (2 bits, measurement type);

[0109] Number = 29 (5 bits, option number, according to IANA specifications, select the undefined value 29);

[0110] Option Length = 6;

[0111] Option Data = S-NSSAI (4 bytes, slice ID).

[0112] 2. Specific method of extending the IPv6 message: The S-NSSAI is carried in the hop-by-hop options header of the IPv6 message. Specifically, the slice information is encapsulated through the newly defined options of the hop-by-hop extension header.

[0113] In an embodiment of the present invention, the hop-by-hop options header of the IPv6 message includes a slice ID option, and the slice ID option includes: option type, option length, and option data.

[0114] Specifically, such as Figure 4 As shown in Figure 1, the IPv6 extension header uses the Hop-by-Hop Options header to define a new Slice ID option and add slicing information to the message. The Hop-by-Hop Options header is an option that must be processed by every node in the network transmission path and can carry multiple functional options simultaneously in the TLV (Tag, Length, Value) format. The Slice ID option is defined as follows:

[0115] Option Type = 214 (0001 0010):

[0116] Action = 0 (2 bits, if the option cannot be recognized, ignore this option and continue processing the extension header);

[0117] CHG=0 (1 bit, option data cannot be changed);

[0118] Sub-type = 18 (5 bits, option number, undefined value 18 selected according to IANA specifications);

[0119] Option Length = 4 (1 byte);

[0120] Option Data = S-NSSAI (4 bytes).

[0121] In an embodiment of the present invention, the IP message sent by the UPF to the forwarding device of the IP bearer network carries information about the network slice, so that the forwarding device of the IP bearer network can perform quality assurance on the slice service according to the control policy of the network slice, thereby expanding the protection scope of the end-to-end slice and improving the user's end-to-end service experience.

[0122] See also Figure 5 , Figure 5 This is a flow chart of a message processing method provided by an embodiment of the present invention, which is applied to a service provider's network equipment, such as Figure 5 As shown, the following steps are included:

[0123] Step 501: Send a second IP packet to a forwarding device of an IP bearer network, wherein the second IP packet carries information about a network slice.

[0124] In this embodiment of the present invention, end-to-end services can be provided by an IPv4 bearer network or an IPv6 bearer network as needed. Accordingly, the second IP packet may include both an IPv4 packet and an IPv6 packet. In practical applications, both IPv4 and IPv6 packets are extended to enable them to carry S-NSSAI. The extension methods for both IPv4 and IPv6 packets can be described in the preceding embodiments.

[0125] The network equipment of the service provider may be a server, etc.

[0126] In an embodiment of the present invention, the IP message sent by the service provider's network equipment to the forwarding equipment of the IP bearer network carries information about the network slice, so that the forwarding equipment of the IP bearer network can ensure the quality of the slice service according to the control policy of the network slice, thereby expanding the protection scope of the end-to-end slice and improving the user's end-to-end service experience.

[0127] See also Figure 6 , Figure 6 This is a flow chart of a message processing method provided by an embodiment of the present invention, which is applied to a forwarding device of an IP bearer network, such as Figure 6 As shown, the following steps are included:

[0128] Step 601: Receive IP packets sent by UPF and / or service provider's network equipment, wherein the IP packets carry information about network slices.

[0129] Specifically, in the upstream direction, the forwarding device of the IP bearer network receives the IP message sent by the UPF; in the downstream direction, the forwarding device of the IP bearer network receives the IP message sent by the service provider's network device.

[0130] The IP packet carries network slicing information. The network slicing information includes S-NSSAI. The IP packet includes an IPv4 packet, and the S-NSSAI is carried in an options field of the IPv4 packet. Alternatively, the IP packet includes an IPv6 packet, and the S-NSSAI is carried in a hop-by-hop options header of the IPv6 packet. For a specific carrying method, reference may be made to the description of the aforementioned embodiment.

[0131] Step 602: Obtain a control strategy based on the information of the network slice.

[0132] The IP bearer network's management and control system obtains network slice information and related SLA requirements (latency, bandwidth, packet loss, etc.) from the operator's BOSS (Business & Operation Support System) system (via the CSMF (Communication Service Management Function)). The IP bearer network leverages existing quality assurance technologies (e.g., priority scheduling, resource reservation, traffic engineering, etc.) to provide SLA guarantees for network slices on demand. The IP bearer network's management and control system then distributes the corresponding control policies to the IP bearer network forwarding devices.

[0133] Therefore, the forwarding device of the IP bearer network can obtain the control policy of the network slice from the management and control system of the IP bearer network based on the information of the network slice.

[0134] Step 603: Use the control strategy to ensure the quality of the network slice.

[0135] In an embodiment of the present invention, the IP message sent by the UPF or the service provider's network equipment to the forwarding device of the IP bearer network carries information about the network slice, so that the forwarding device of the IP bearer network can perform quality assurance on the slice service according to the control policy of the network slice, thereby expanding the protection scope of the end-to-end slice and improving the user's end-to-end service experience.

[0136] See also Figure 7 , Figure 7 Schematic diagram of a message processing system provided by an embodiment of the present invention. The system may include: an access network, a transmission network, a core network, an IP bearer network, and a service provider network.

[0137] In view of the limitation that the current end-to-end perception and assurance scheme of 5G network slicing only focuses on the distance from user terminals to the core network, in an embodiment of the present invention, a perception and assurance method for 5G network slicing services in an IP bearer network is proposed. In the uplink message (from the core network to the service provider network), the core network UPF encapsulates the network slicing information into an IP message and sends it to the IP bearer network. In the downlink message (from the service provider network to the core network), the server of the service provider network adds the network slice information to the IP message and then sends the IP message to the IP bearer network.

[0138] In the embodiments of the present invention, end-to-end services can be provided by either an IPv4 bearer network or an IPv6 bearer network as needed. Therefore, in practical applications, IPv4 and IPv6 packets are extended to carry network slice information, such as S-NSSAI. The extension method can be referred to in the description of the preceding embodiments.

[0139] The IP bearer network's management and control system obtains network slice SLA service quality requirements from the operator's BOSS system, sets control policies, and distributes them to IP bearer network forwarding devices as needed. IP bearer network forwarding devices identify slice services by parsing network slice information, such as S-NSSAI, in IP packets on demand. They then match the corresponding control policies, ensuring the SLA requirements of network slice services at the forwarding layer. IP bearer network quality assurance technologies include, for example, priority scheduling, resource reservation, and traffic engineering.

[0140] Specifically, when a network slice is created, CN-NSSMF (core network slice subnet management) notifies UPF of the mapping relationship between vlan-id and network slice ID (S-NSSAI), and UPF saves the mapping table.<vlan-id,S-NSSAI> After the service provider orders / signs a slice from the operator, it can obtain the corresponding network slice ID (S-NSSAI).

[0141] In the uplink direction (core network to service provider network), when the slice message leaves the core network UPF and enters the IP bearer network, the UPF obtains the slice ID from the mapping table through the message vlan-id and encapsulates it into the IP data message; in the downlink direction (service provider network to core network), when the service provider network provides slicing service, the server of the service provider network adds the network slice ID to which the service belongs to the IP message.

[0142] The IP bearer network management and control system obtains network slice information and related SLA requirements (latency, bandwidth, packet loss, etc.) from the operator's BOSS system. Leveraging existing quality assurance technologies (such as priority scheduling, resource reservation, and traffic engineering), it provides SLA guarantees for slices on demand and distributes the corresponding control policies to the forwarding devices of the IP bearer network. The forwarding devices of the IP bearer network identify the slice ID carried in the IP packet and match it with the corresponding control policy, thereby ensuring the SLA requirements of the network slice service at the forwarding level.

[0143] It can be seen from the above description that in the embodiment of the present invention, the IP bearer network can perceive the information of the network slice, and then can perform quality assurance on the network slice service according to the SLA of the network slice on the IP bearer network, thereby expanding the scope of protection of the end-to-end network slice. In the embodiment of the present invention, the slice perception method takes into account two types of network types, IPv4 and IPv6, and carries the unique slice ID of the entire network through the option field of the IPv4 packet header and the newly defined option of the IPv6 hop-by-hop extension header, without the need for new hardware. In addition, the IP bearer network can upgrade the software perception and processing network slice information of specific equipment as needed, and no software updates are required for other equipment. Therefore, the embodiment of the present invention can be flexibly deployed on demand without affecting existing services. Among them, the above-mentioned slice perception method is also applicable to service provider networks (such as user data center networks, content service provider networks, etc.), thereby achieving complete client-to-end slice service guarantee.
