Detailed Description

Before the technical solution of the embodiment of the present invention is introduced, a description is given of a related art.

In the related technology, the network slice is a typical characteristic of a 5G network, is vertical to the industry through a logic 'private network' service, and is a powerful gripper for an operator to expand industry customers, promote new services and improve network value. The network slice has the advantages that the operator can select the characteristics required by each slice, such as low delay, high throughput, connection density, spectrum efficiency, traffic capacity and network efficiency, so that the operator provides differentiated services on the basis of not increasing investment cost, the customized requirements of customers are met, and the customer experience is improved. The 5G network slicing relates to multiple fields of wireless networks, transmission networks and core networks, and end-to-end slicing is realized by butting in different fields. The wireless field and the core network field realize the unique identification of the slicing service based on NSSAI. The transmission domain performs transmission slice identification based on the VLAN ID. At present, a transport Network forwarding layer realizes slices with different isolation degrees through mechanisms such as an MTN interface, an MTN channel, a Virtual Private Network (VPN), Quality of Service (Qos), and the like, different transmission slices adopt different VLAN ID identifications, and a correspondence between a transmission slice and a VLAN ID identification is 1: 1. The transmission slice does not sense NSSAI, and the corresponding relation between NSSAI and VLAN ID is M: N. The wireless network and the transmission network, and the core network and the transmission network are all slice-jointed based on VLAN ID, so that VLAN ID identification needs to be configured on network elements of the wireless network, the transmission network and a network element forwarding layer of the core network.

Fig. 1 is a schematic diagram of a mapping relationship between NSSAI and VLAN ID in the related art, and as shown in fig. 1, a base station on a Radio Access Network (RAN) side and a Slice Packet Network (SPN) device on an Access stratum (nas) are connected between forwarding planes through a standard ethernet user interface (i). RAN identifies the slicing service through NSSAI, configures VLAN ID according to NSSAI and VLAN ID mapping table when forwarding the message to transmission SPN, and configures VLAN PRI and IP DSCP according to priority mapping table. The SPN performs slice identification through a port + VLAN ID + priority mode, and maps the message to different SPN slice tunnels. The Network elements of the Core Network (CN) and the SPN are connected via a standard ethernet user interface (c). The SPN forwards the message with the VLAN ID + priority to a network element of a core network based on different slice tunnels. The network element of the core network identifies NSSAI based on the NSSAI and VLAN ID mapping table, and realizes the identification of the core network priority based on the priority mapping table, thereby realizing the internal slicing of the core network. The forwarding layer downlink slice docking manner is symmetrical to the uplink docking manner, and details are not described here.

In summary, the technical defects in the related art are: the VLAN ID is determined in a manual designation mode, namely, service initiating personnel manually designate the VLAN ID, then the VLAN ID is issued in a work order mode, and operation and maintenance personnel configure the issued VLAN ID to forwarding layer equipment in each field by using a network manager. At present, no mechanism and method for automatically distributing VLAN IDs exist.

Based on this, in various embodiments of the present invention, index data of a slicing service is obtained; analyzing the index data to obtain the type of the network slice corresponding to the slice service; determining a VLAN identification corresponding to the type of the network slice; sending the VLAN identification to a slice management function NSMF entity; the VLAN identification is for the NSMF entity to send to a second NSSMF entity in a wireless network and a third NSSMF entity in a core network.

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Fig. 2 is a schematic diagram of a system architecture applied by the identifier allocation method according to the embodiment of the present invention, and as shown in fig. 2, the system includes:

and an end-to-end slice management system (NSMF) for implementing end-to-end network slice management.

And the sub-slice management system (TN NSSMF) in the transmission network is used for realizing the full life cycle management of the transmission network slice.

And the sub-slice management system (AN NSSMF) in the wireless network is used for realizing the full-life-cycle management of the wireless network slices.

And the core network sub-slice management system (CN NSSMF) is used for realizing the full life cycle management of the core network slices.

And the Super Controller (SC) is used for realizing cross-domain service control of the transmission SPN.

A control integrated Domain Controller (DC) for realizing management and control of single domain service; wherein the control-and-regulation-integrated Domain Controller (DC) is directly connected with the transmission equipment.

An embodiment of the present invention provides an identifier allocation method, which is applied to a first NSSMF entity in a transmission network, and as shown in fig. 3, the method includes:

step 301: acquiring index data of a slicing service; analyzing the index data to obtain the type of the network slice corresponding to the slice service;

step 302: determining a VLAN identification corresponding to the type of the network slice;

step 303: sending the VLAN identification to an NSMF entity; the VLAN identification is for the NSMF entity to send to a second NSSMF in the wireless network and a third NSSMF in the core network.

Here, in step 301, the NSMF entity may obtain a slicing service request from another service system, such as a Communication Service Management Function (CSMF) entity, when actually applied; the slice service request carries an end-to-end service index; the NSMF entity disassembles the end-to-end service index, and splits the service index into a wireless network, a transmission network and a core network service index, and sends the service index of the transmission network to a first MSSMF entity in the transmission network, and the first NSSMF entity analyzes the service index to determine the network slice type of the transmission slice service. Wherein the type of the network slice may include: the shared hard slice, the independent VPN soft slice, and the shared VPN soft slice are four slice types. Different types of network slices can meet different service requirements and implement different service characteristics.

Here, in step 302, the VLAN identification may refer to an identification of a virtual router in the transport network.

Here, in step 303, since the NSMF entity is capable of communicating with the second NSSMF in the wireless network and the third NSSMF in the core network, the first NSSMF entity in the transport network may send the VLAN id corresponding to the type of the network slice to the NSMF entity, and the NSMF entity forwards the VLAN id to the second NSSMF in the wireless network and the third NSSMF in the core network.

In practical application, after obtaining the type of the network slice, the first NSSMF entity in the transmission network may first determine whether the existing transmission slice may be multiplexed, and when it is determined that the existing transmission slice may be multiplexed, because the existing transmission slice has the corresponding VLAN identifier, the existing VLAN identifier may be reported to the NSMF entity, so that the NSMF entity may forward the NSSMF to the second NSSMF in the wireless network and the third NSSMF in the core network.

Based on this, in an embodiment, the determining the VLAN id corresponding to the type of the network slice includes:

In an example, as shown in fig. 4, in conjunction with the schematic system structure shown in fig. 2, a process of determining a VLAN identifier by a first NSSMF entity in a transport network is described, which includes:

step 401: acquiring index data of a slicing service;

here, a first NSSMF entity in the transmission network acquires index data of the slicing service from an NSMF entity; the index data of the slicing service comprises: delay, bandwidth, isolation, service type (L2VPN/L3VPN), subnet template ID (optional), transport network service type (optional), whether to multiplex the existing service (optional), service access network element, port and routing information, slicing subnet instance NSSAI ID (optional), etc.

Step 402: analyzing the index data to obtain the type of the network slice corresponding to the slice service;

here, the type of the network slice is one of: an exclusive hard slice, a shared hard slice, an independent VPN soft slice, and a shared VPN soft slice.

Here, in the fifth generation communication system, the first NSSMF entity in the transmission network may implement soft slicing and hard slicing by combining technical means such as an MTN interface, an MTN channel, a VPN, and Qos.

Step 403: judging whether a transmission slice needs to be newly added for carrying out service bearing; when it is determined that no new transmission slice is needed for service bearer, step 404 is executed.

Here, after the first NSSMF entity in the transmission network obtains the service index of the transmission domain and analyzes and determines the network slice type of the transmission slice service, it may be determined whether a new transmission slice needs to be added for carrying the slice service.

Here, when it is determined that the type of the network slice is stored in the preset database, it is determined that a new transmission slice is not needed to carry out the slice service.

Step 404: and obtaining the VLAN identification corresponding to the type of the network slice from a preset database, and reporting the VLAN identification to the NSMF entity.

Here, after the VLAN ID of the existing transmission slice is returned to the upper NSMF entity, the NSMF entity may issue an acknowledgement operation to the TN NSSMF; if the existing slice needs to be adjusted, the TN NSSMF performs service modification operation downwards; if no modification to the existing service is required, the downward flow is terminated.

Here, the first NSSMF entity (TN NSSMF in fig. 2) in the transport network determines the VLAN id, which has the following advantages:

(1) the TN NSSMF can determine the network slice type of the transmission slice service according to the index data of the slice service, so that whether a new transmission slice is needed to carry out service bearing can be judged based on the determined network slice type.

(2) And when the TN NSSMF judges that no new transmission slice needs to be added for carrying the service based on the definite network slice type, determining a VLAN identification corresponding to the network slice type from a preset database, subsequently reporting the VLAN identification to an NSMF entity, and allocating the VLAN identification to NSSMF entities of a wireless network and a core network by the NSMF entity.

In practical application, after obtaining the type of the network slice, a first NSSMF entity in a transmission network may first determine whether the existing transmission slice may be multiplexed, and when it is determined that the existing transmission slice cannot be multiplexed, a lower layer entity of the first NSSMF entity in the transmission network may report an available VLAN identifier, and the first NSSMF entity selects a VLAN identifier matching the type of the network slice from the reported VLAN identifiers.

In an example, as shown in fig. 5, in conjunction with the schematic system structure shown in fig. 2, a process for determining a VLAN identifier by a first NSSMF entity in a transport network is described, where the process includes:

step 501: acquiring index data of a slicing service;

Step 502: analyzing the index data to obtain the type of the network slice corresponding to the slice service;

Step 503: judging whether a transmission slice needs to be newly added for carrying out service bearing; when it is determined that a new transmission slice is needed for service bearer, step 504 is executed.

Here, when it is determined that the type of the network slice is not stored in the database, it is determined that a new transmission slice is required to carry out a slice service.

Step 504: sending a query request to the SC; the query request is used for requesting the SC to acquire available VLAN identifications from a plurality of DCs;

step 505: the SC sends a query request to the plurality of DCs.

Step 506: the plurality of DCs respectively send a first set of VLANs to the SCs.

Step 507: the SC sends a plurality of first VLAN sets to a first NSSMF entity in the transport network.

Step 508: a first NSSMF entity in the transmission network determines VLAN IDs corresponding to network slice types based on a plurality of first VLAN set IDs returned by the SC.

Here, the first NSSMF entity in the transmission network reports the determined VLAN ID to the NSMF; the NSMF issues a confirmation operation to the TN NSSMF, and the TN NSSMF performs a service creation operation downwards. The NSMF issues the received VLAN ID to CN NSSMF and AN NSSMF, and the CN NSSMF and the AN NSSMF issue and configure the VLAN ID.

(2) And when the TN NSSMF judges that a transmission slice needs to be newly added for carrying out service bearing based on the clear network slice type, namely, the TN NSSMF requests available VLAN ID information from the SC aiming at the scene that the transmission slice needs to be newly added, and determines the VLAN ID corresponding to the network slice type based on a plurality of first VLAN set IDs returned by the SC.

In practical application, the first NSSMF entity of the transmission network may plan an applicable VLAN identifier segment according to a corresponding service type for different network slice types, and may select a VLAN identifier corresponding to a network slice type from a plurality of VLAN sets reported by a DC in combination with the planned VLAN identifier segment after acquiring an available VLAN set reported by the plurality of DCs from the SC.

Based on this, in an embodiment, the determining, based on the plurality of first VLAN sets, a VLAN identification corresponding to the type of the network slice includes:

acquiring the type of the slicing service;

Here, the first NSSMF entity in the transmission network may plan the VLAN ID according to the slice service type corresponding to the network slice type, and record the planned VLAN ID into the database. Specifically, a segment of VLAN ID may be respectively planned for an individual hard slice, a shared hard slice, and an individual VPN soft slice, and a default VLAN ID may be adopted for a shared VPN soft slice.

For example, table 1 shows the correspondence between the network slice type and the corresponding slice service type, and as shown in table 1, the network slice type includes: the service type of the slice corresponding to the independent hard slice can be a highest-end service, the service type of the slice corresponding to the shared hard slice can be a middle-high-end service, the service type of the slice corresponding to the independent VPN soft slice can be a middle-end service, and the service type of the slice corresponding to the shared VPN soft slice can be a low-end service. The grade of the service can be divided according to the indexes of the service, such as time delay, bandwidth and the like.

Network slice type	Slicing service type
		Exclusive hard slice	Top end service
Sharing hard slices	Middle and high end service
		Independent VPN soft slice	Middle-end service
Shared VPN soft slice	Public business

TABLE 1

Table 2 shows the correspondence between the slice service type and the planned VLAN set, and as shown in table 2, the planned VLAN set is {0, 1, …,1000} for the top-end service, the planned VLAN set is {1001, 1002, …,2000} for the medium-high-end service, the planned VLAN set is {2001, 2002, …,3000} for the medium-end service, and the planned VLAN set is {3001, 3002, …,4096} for the mass service.

Slicing service type	VLAN aggregation
		Top end service	{0，1，…,1000}
Middle and high end service	{1001，1002，…,2000}
		Middle-end service	{2001，2002，…,3000}
Public business	{3001，3002，…,4096}

TABLE 2

In practical application, in order to ensure that the finally determined VLAN identifier corresponding to the network slice type is available, the intersection of a plurality of second VLAN sets reported by a plurality of DCs may be taken to obtain a third VLAN set, and in order to ensure that the finally determined VLAN identifier corresponding to the network slice type is suitable for the slice service corresponding to the network slice type, the intersection of a VLAN set planned for the slice service and the third VLAN set may be taken to obtain a fourth VLAN set, and the VLAN identifier corresponding to the network slice type is selected from the fourth VLAN set.

Based on this, in an embodiment, the determining, based on the second VLAN set and the plurality of first VLAN sets, a VLAN identification corresponding to a type of the network slice includes:

In practical application, the intersection of the VLAN set planned for the slice service and the third VLAN set is taken to obtain a fourth VLAN set, and one VLAN identification is selected from the fourth VLAN set to serve as the VLAN identification corresponding to the type of the network slice. The rule of selection may be random selection, or may be selection in order from small to large, and is not limited herein.

Based on this, in an embodiment, the determining, based on the fourth VLAN set, a VLAN id corresponding to the type of the network slice includes:

In an example, as shown in fig. 6, a process of determining, by a first NSSMF entity of a transport network, a VLAN id corresponding to a network slice type based on a planned second VLAN set and a plurality of first VLAN sets reported by an SC is described, where the process includes:

step 601: taking intersection of the plurality of first VLAN sets to obtain a third VLAN set;

assuming that a plurality of the first set of VLANs is represented by set 1, set 2, set 3, and a third set of VLANs is represented by set 4; the set 1 is {0, 1, …,400}, the set 2 is {200, 201, …,400}, the set 3 is {300, 301, …,400}, and the set 4 is {300, 301, …,400 }.

Step 602: combining and intersecting the third VLAN set and the second VLAN set to obtain a fourth VLAN set;

assuming that the second VLAN set is {350, 351, …,4000}, the third VLAN set intersects with the second VLAN set, and the resulting fourth VLAN set is {350, 351, …,400 }.

Step 603: sequencing all VLAN identifications in the fourth VLAN set to obtain a sequencing result; selecting a VLAN identifier from the sequencing result according to the sequence from small to large; and taking the selected VLAN identification as the VLAN identification corresponding to the type of the network slice.

Here, the VLAN with the smallest rank in the fourth VLAN set may be defined as 350 as the VLAN id corresponding to the type of the network slice. If the VLAN id is already used by another network slice, the VLAN id 351 may be used as the VLAN id corresponding to the type of the network slice.

Here, the first NSSMF entity (TN NSSMF in fig. 2) of the transport network determines the VLAN id corresponding to the network slice type based on the planned second VLAN set and the plurality of first VLAN sets reported by the SC, which has the following advantages:

(1) and the TN NSSMF entity analyzes based on the available VLAN ID returned by the lower layer and the condition of the planned VLAN ID in the database, determines the VLAN ID corresponding to the type of the network slice, and reports the VLAN ID to the NSMF entity.

(2) And the NSMF entity sends the VLAN ID corresponding to the network slice type returned by the TN NSSMF to the CN NSSMF and the AN NSSMF.

In practical application, the NSSAI network slice is used in the wireless network field, the VLAN network slice is used in the transmission network field, and the NSSAI network slice is used in the core network field, so as to implement end-to-end network slicing, so that when a second NSSMF entity of the wireless network uses the network slice to transmit a slicing service to the transmission network, a VLAN id corresponding to the NSSAI i needs to be identified, so that the first NSSMF entity in the transmission network can identify the network slice, and similarly, when a first NSSMF entity in the transmission network uses the network slice corresponding to the VLAN id to transmit a slicing service to a second NSSMF entity in the core network, the NSSAI id corresponding to the VLAN id needs to be identified, so that a third NSSMF entity in the core network can identify the network slice, so that the first NSSMF entity in the transmission network can establish a corresponding relationship between the VLAN id and the NSSAI id, and the established corresponding relationship between the VLAN id and the NSSAI id can be configured to the second nsf entity in the core network and the third NSSMF entity in the wireless network by the NSMF entity .

Based on this, in an embodiment, the sending the VLAN id to a slice management function NSMF entity includes:

establishing a corresponding relation between the VLAN identification and the NSSAI identification;

sending the established corresponding relation between the VLAN identifier and the NSSAI identifier to an NSMF entity; the corresponding relation is used for the NSMF entity to be configured to a second NSSMF entity of a wireless network and a third NSSMF entity of a core network.

In an example, as shown in fig. 7, a process for a first NSSMF entity of a transport network to configure the VLAN id to a second NSSMF entity of a wireless network and a third NSSMF entity in a core network is described, which includes:

step 701: determining NSSAI identification corresponding to the network slice type;

step 703: sending the established corresponding relation between the VLAN identifier and the NSSAI identifier to an NSMF entity; the corresponding relation is used for the NSMF entity to be configured to a second NSSMF entity of a wireless network and a third NSSMF entity of a core network.
