It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
One network slice example is composed of three sub-network slice examples of a radio access network, a bearer and a core network, and end-to-end slice management is realized through NSMF (Network Slice Management Function ).
Fig. 1 illustrates a network scenario diagram according to some embodiments of the invention. As shown in fig. 1, the NSMF 12 interacts with a radio access network subnet slice manager (AN-NSSMF) 131, a bearer network subnet slice manager (TN-NSSMF) 132, and a core network subnet slice manager (CN-NSSMF) 133, respectively, through different interfaces. The AN-NSSMF 131 configures the radio access network slice directly or indirectly through the network management, the TN-NSSMF 132 configures the carrier network slice directly or indirectly through the network management, and the CN-NSSMF 133 configures the core network slice directly or indirectly through the network management. CSMF11 may issue a slice creation request to NSMF 12.
The base stations on the RAN (Radio Access Network ) 141 side and the access devices carrying the network 142 are connected between the forwarding planes by means of a standard ethernet user interface. In some embodiments, radio access network 141 identifies sub-slice instances of radio access network 141, e.g., by AN-nsi ID. Before the radio access network 141 forwards the data packet to the bearer network 142, the data packet is configured according to the mapping relationship between the AN-nsi ID and the butt-joint identifier of the sub-slice. After receiving the data packet, the carrier network 142 performs slice identification through the docking identifier, and forwards the packet to the corresponding carrier network slice instance.
The core network 143UPF and the edge devices of the carrier network 142 are connected between the forwarding planes via a standard ethernet user interface. In some embodiments, the core network 143 identifies sub-slice instances of the core network by CN-NSSI ID. When forwarding the packet to the carrier network 142, the data packet is configured according to the mapping relationship between the CN-nsi ID and the butt-joint identifier of the sub-slice. After receiving the data packet, the carrier network 142 performs slice identification through the docking identifier, and forwards the packet to the corresponding carrier network slice instance.
An embodiment of a configuration method of end-to-end network slice docking is described below with reference to fig. 2.
Fig. 2 illustrates a flow diagram of a method of configuring end-to-end network slice interfacing according to some embodiments of the invention. As shown in fig. 2, the configuration method of the end-to-end network slice docking of this embodiment includes steps S202 to S210.
In step S202, the NSMF obtains the docking information of the carrier network slice and the radio access network slice, and the docking information of the carrier network slice and the core network slice.
In some embodiments, the docking information of the carrier network sub-slice with the wireless access network sub-slice includes an identification of the base station, a port identification of the base station, an identification of a first docking device of the carrier network. The base station is a base station in a radio access network. In some embodiments, the first docking device of the bearer network is an access device.
In some embodiments, the docking information of the carrier network sub-slice with the core network sub-slice includes an identification of the UPF, a port identification of the UPF, an identification of a second docking device of the carrier network. In some embodiments, the second docking device of the carrier web is an edge device.
In step S204, in response to obtaining the slice creation request information, the NSMF allocates a docking identifier of the carrier network slice and the radio access network slice, and a docking identifier of the carrier network slice and the core network slice according to the docking information. The content of the two identifications may be the same or different.
In some embodiments, the slice creation request information is sent by CSMF (Communication Service Management Function ).
In some embodiments, the unified docking identity is a VLAN ID (virtual local area network identity). For example, the docking identifier is a VLAN identifier of one sub-port of the interconnect port, and each interconnect port may be configured with a plurality of VLAN sub-interfaces corresponding to different docking identifiers. Thus, when encapsulating a data message, the VLAN ID is used to represent the docking identity.
In step S206, the NSMF issues sub-slice creation requests to the bearer network sub-network slice manager (hereinafter abbreviated as TN-NSSMF), the radio access network sub-network slice manager (hereinafter abbreviated as AN-NSSMF), and the core network sub-network slice manager (hereinafter abbreviated as CN-NSSMF), respectively, each of which includes a corresponding docking identifier and docking information.
In some embodiments, when the subnet slice manager integrates the network management function, the subnet slice manager directly creates the sub-slice instance; when the subnet slice manager does not integrate the network management function, the subnet slice manager creates the sub-slice instance indirectly through the network management.
In some embodiments, the slice creation request information acquired by the NSMF includes SLA indexes of the slice, and the NSMF performs sub-slice decomposition on the SLA indexes to generate access network SLA indexes, carrier network SLA indexes and core network SLA indexes; the NSMF then includes the decomposed corresponding metrics in the sub-slice creation request and issues them so that each sub-net slice manager references these metrics when creating the sub-slice instance.
In step S208, TN-NSSMF, AN-NSSMF, and CN-NSSMF create sub-slice instances, respectively.
After the slices are created, the butt-joint information between the sub-slices of different networks becomes the butt-joint information between the sub-slice instances of the corresponding network.
In step S210, the TN-NSSMF, the AN-NSSMF, and the CN-NSSMF configure docking identifiers on the corresponding docking device and the interconnection port, respectively, according to the docking information between the sub-slices.
According to the embodiment, the NSMF uniformly distributes the butt joint identifiers and transmits the butt joint identifiers to each subnet slice manager, and each subnet manager configures the butt joint identifiers according to the acquired information, so that the end-to-end automatic configuration of the network slices is realized, and the configuration efficiency and the configuration accuracy are improved.
In some embodiments, the information of the bearer network slice interfacing with the radio access network slice and the information of the bearer network slice interfacing with the core network slice are obtained by the bearer network interfacing device via a link layer discovery protocol (Link Layer Discovery Protocol, abbreviated LLDP). An embodiment of the docking information acquisition method is described below with reference to fig. 3A and 3B.
Fig. 3A illustrates a flow diagram of a docking information acquisition method according to some embodiments of the invention. As shown in fig. 3A, the docking information acquisition method of this embodiment includes steps S302 to S304.
In step S302, the carrier network docking device automatically discovers the base station ID and port ID information of the wireless base station interconnected with the carrier network docking device, and the UPF ID and port ID information of the UPF interconnected with the carrier network docking device, through the LLDP protocol.
Fig. 3B schematically illustrates a relationship between devices in a network. As shown in fig. 3B, the carrier network router is used as a carrier network docking device, and interacts with the wireless base station and the core network UPF through the LLDP protocol to obtain docking information.
In step S304, the bearer network docking device sends the acquired docking information to the NSMF through the TN-NSSMF.
Because the interface is arranged between the TN-NSSMF and the NSMF, the interface can be used for reporting the collected butt joint information.
By the embodiment, the butt joint information among the sub-slices of the bearing network sub-network, the wireless access network sub-network and the core network sub-network can be automatically found, and the efficiency of automatic configuration of the network slices is improved.
In some embodiments, after each subnet establishes a sub-slice instance, the NSMF may establish a correspondence between the docking identity and other information. An embodiment of the mapping relation establishment method is described below with reference to fig. 4.
Fig. 4 is a flow chart illustrating a mapping relationship establishment method according to some embodiments of the present invention. As shown in fig. 4, the mapping relation establishment method of this embodiment includes steps S402 to S404.
In step S402, NSMF obtains identifiers of sub-slice instances sent by TN-NSSMF, AN-NSSMF and CN-NSSMF, respectively.
In step S404, the NSMF establishes a first mapping relationship between the identifiers of the sub-slice instances created by the TN-NSSMF and the AN-NSSMF, the docking information and the docking identifiers of the bearer network sub-slices and the radio access network sub-slices, and a second mapping relationship between the identifiers of the sub-slice instances created by the TN-NSSMF and the CN-NSSMF, the docking information and the docking identifiers of the bearer network sub-slices and the core network sub-slices.
Table 1 exemplarily shows an example of the first mapping relation, and table 2 exemplarily shows an example of the second mapping relation. TN-NSSI ID, AN-NSSI ID, CN-NSSI ID respectively represent the identity of sub-slice examples of the bearer network, the radio access network, and the core network.
TABLE 1
TABLE 2
Thus, NSMF can record and maintain end-to-end information of the network slice for more convenient monitoring, maintenance and management.
In some embodiments, the NSMF may further issue the first mapping relationship to the TN-NSSI ID and the AN-NSSI ID, and issue the second mapping relationship to the TN-NSSMF and the CN-NSSMF, so that each subnet slice manager can know related information of the subnet where the subnet is located. Each sub-network slice manager may further issue part or all of the mapping relationship to a docking device in the network.
In some embodiments, after configuration of the docking identity is completed, for the docking device in each of the radio access network, the bearer network, the core network: the docking equipment sends the docking identification to the corresponding sub-slice example for processing according to the docking identification of the received data message; and the docking equipment encapsulates the service message into a data message with a corresponding docking identifier according to the sub-slice instance corresponding to the processed service message, and sends the encapsulated data message to the next network through a corresponding interconnection port. Therefore, the docking equipment of each subnet can realize the end-to-end transmission of the service data related to the slice by using the configured docking identification. Embodiments of forwarding data messages based on configured docking identifiers are described below with reference to fig. 5A and 5B.
Fig. 5A illustrates three specialized network connection schematics according to some embodiments of the present invention. As shown in fig. 5A, the docking device in the carrier network includes an access router 52 and an edge router 53. The interfacing of the sub-network slices is achieved between the radio base station 51 and the access router 52 in the radio access network, and between the core network UPF54 and the edge router 53 by means of the interfacing identification VLAN ID.
Fig. 5B is a flow diagram illustrating a method of forwarding a data packet according to some embodiments of the present invention. This embodiment is described by taking uplink data packet transmission as an example, and the configuration of each device, port, and identifier in this embodiment is referred to in table 1 and table 2. As shown in fig. 5B, the data packet forwarding method of this embodiment includes
In step S502, the radio base station NB 1 adds the docking identifier VLAN1 to the data packet to be sent to the bearer network according to the docking identifier VLAN1 configured for docking the radio access network slice AN-NSSI 1 and the bearer network slice TN-NSSI 1, and encapsulates the data packet.
In step S504, the radio base station NB 1 transmits the encapsulated data packet to the docked bearer network access device A1 through the designated port P1.
In step S506, after receiving the data packet sent by the radio base station NB 1, the bearer network access device A1 identifies that the bearer network service slice docking identifier VLAN1 is carried therein, and sends the service packet to the corresponding service slice for processing according to the mapping relationship between the configured slice docking identifier VLAN1 and the bearer network slice TN-NSSI 1. The processing includes, for example, peeling the docking mark, dicing the package, and the like.
In step S508, the carrier network edge device B1 encapsulates the configured docking identifier VLAN1, that is, the docking identifier between the carrier network slice TN-NSSI 1 and the core network slice CN-NSSI 1, for the processed data packet, and sends the docking identifier VLAN1 to the docked core network UPF 1 device through the designated port P1.
In step S510, after receiving the data packet sent by the bearer network, the UPF 1 of the core network forwards the data packet to the core network slice CN NSSI 1 corresponding to VLAN1 for processing according to the docking identifier VLAN1 carried by the data packet.
Through the embodiment, each device in the wireless access network, the bearing network and the core network can realize the correct forwarding of the data message through the preset automatic configuration of the butt joint identifiers.
The forwarding process of the data message in the downlink direction from the core network to the bearer network and then to the radio access network is similar to the above-mentioned processing process, and will not be repeated here.
