All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
In making the description of the embodiments of the present application, some concepts used in the following description will first be explained.
A network slice is an end-to-end logical private network that provides specific network capabilities. One example of a network slice is a set of physical and virtual resources required and composed of sub-network slice instances of the wireless, transport and core networks.
In order to realize the management of the network slice, the management function of the network slice is newly added in the 5G network, and the management function comprises the following steps: fig. 1 shows an overall architecture of a Network Slice Management system, where OMC is an operation maintenance center, NFVO is a Network Function virtualization orchestrator, VNFM is a virtualization Network Function manager, EMS is a Network element Management system, and VIM is virtual interconnection Management.
CSMF: and completing the requirement ordering and processing of the user business communication service, and converting the communication service requirement into the network slicing requirement for NSMF.
NSMF: receiving a network slice deployment request issued from the CSMF, decomposing a Service-Level Agreement (SLA) requirement of the network slice into an SLA requirement of a network slice subnet, and issuing the network slice subnet deployment request to the NSSMF.
NSSMF: according to the professional field, the method is divided into wireless NSSMF, transmission NSSMF and core network NSSMF. NSSMF in each field receives the network slice subnet deployment requirement issued by NSMF, converts SLA requirement of the network slice subnet into network element service parameter and issues to network element. For the core network field, the resource requirements of the network slice subnet are converted into network services, and a deployment request of the network services is issued to a Network Function Virtualization (NFV) NFVO system.
In the existing network slice instantiation process, for sharable Network Slice Instances (NSI), matching and multiplexing of existing Network Slice Subnet Instances (NSSI) according to a network slice subnet service attribute (SliceProfile) is supported. For shareable Network Slice Subnet Instances (NSSI), the creation of multiple network slice subnet services on an instance is supported and all network slice subnet service requirements are met.
When creating a network slice subnet, the NSMF will decompose the network slice requirement into a network slice subnet requirement, and issue the deployment requirement of the network slice subnet to the NSSMF or be directly triggered on the NSSMF by an operator. The request includes parameters such as a network slice service identifier (S-NSSAI), a network slice instance identifier NSI ID, a core network slice subnet template NSST ID, a specification (navigator) ID (which may be selected, if not specified, according to a default navigator), a SliceProfile, and required inputs. In the creation of the slicing subnet sharing the NSSI, the NSSMF searches and matches the existing NSSI meeting all requirements according to the NSST and the SliceProfile attributes, and if the corresponding slicing subnet example is not found, the NSSMF carries out processing according to the slicing subnet creation flow of the newly-built example.
The NSSI updating method, apparatus and NSSMF entity provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 2, at least one embodiment of the present application provides a network slice subnet instance NSSI updating method, applied to an updating apparatus, including:
it should be noted that, the first request includes: identification information, a first specification identifier and a first network slice subnet service attribute corresponding to a first Network Slice Subnet Template (NSST);
it should be noted that, in the case that the NSSMF entity does not satisfy the subnet service attribute requirement according to the first NSST and the first network slice subnet service attribute, the first request is sent to the updating apparatus when the dynamic update identifier in the first NSST supports the dynamic update of the first NSSI; here, the first NSSI corresponds to the first specification under the first NSST.
it should be noted that, since the NSST correspondingly includes a plurality of specifications (shaders), this step is to obtain all shaders under the first NSST.
Step 203, acquiring a service attribute of a second network slice subnet of the deployed service on the first NSSI created by the first NSST;
it should be noted that, since the embodiments of the present application are directed to NSSI in a shared situation, that is, when creating NSSI applied to a new network slice subnet service attribute, it is possible that the NSSI is already created, here, the network slice subnet service attribute that has been deployed on the created NSSI is acquired.
the step in the embodiment of the present application is to select a new specification, that is, compare the service attribute of the second sliced subnet and the service attribute of the first sliced subnet with each specification, and select a specification that can simultaneously satisfy the requirements of the service attribute of the second sliced subnet and the service attribute of the subnet corresponding to the service attribute of the first sliced subnet.
specifically, when the updating apparatus acquires the second specification, the identifier information of the second specification is sent to the NSSMF entity to assist the NSSMF entity in updating the first NSSI according to the second specification.
It should be noted that, in order to implement the embodiment of the present application, a dynamic update flag needs to be added to the NSST, and a specific format of the dynamic update flag is shown in table 1:
TABLE 1 specific format for dynamically updating the identity
It should be further noted that, before the acquiring all the specification information corresponding to the first NSST, at least one embodiment of the present application further includes:
and receiving the specification information of the first NSST sent by the NSSMF entity, and storing the specification information.
In general, in a packet uploading process before NSSI creation, an NSSMF entity first obtains a dynamic update flag in a first NSST, and if the dynamic update flag information indicates that NSSI dynamic update is supported, sends specification information of the first NSST to an updating apparatus, and the updating apparatus stores the specification information of the first NSST for subsequent use.
As shown in fig. 3, taking an NSST as an example, the on-package flow of the embodiment of the present application is specifically:
step 301, uploading NSST;
this step is where the operator writes NSST into the NSSMF entity.
Step 302, the NSSMF entity checks the integrity and validity of the NSST;
step 303, acquiring a dynamic update identifier in the NSST by the NSSMF entity;
when the dynamic update flag supports dynamic update of NSSI, step 204 is executed.
Step 304, synchronizing all the navigator information of the NSST to the updating device;
step 305, the updating device stores the navigator information;
step 306, the NSSMF entity stores the NSST and sets the NSST as a starting state;
in step 307, the NSSMF entity returns the upload result to the operator.
Note that this packet upload flow is applicable to upload of all NSSTs.
It should be further noted that, after step 105, at least one embodiment of the present application further includes: receiving first information sent by the NSSMF entity after the establishment of the second NSSI is completed;
wherein the first information comprises: information of a second NSSI and service information deployed in the second NSSI.
That is, when the NSSMF entity receives the identification information of the second specification sent by the updating apparatus, and updates the first NSSI to the second NSSI by using the identification information of the second specification, it needs to send the information of the second NSSI and the service information deployed in the second NSSI to the updating apparatus, and after receiving the information of the second NSSI and the service information deployed in the second NSSI, the updating apparatus updates the information stored in itself, so as to ensure the real-time information stored in the updating apparatus in the network operation process (for example, the network slice subnet service attribute stored in the updating apparatus corresponding to the latest specification), and ensure the accuracy of updating the subsequent NSSI.
As shown in fig. 4, a specific process of creating a sliced subnet in the embodiment of the present application is as follows:
step 401, the NSMF/operator sends a request for creating a slice subnet to the NSSMF entity;
step 402, the NSSMF entity matches the existing first NSSI according to the first NSST and the service attribute of the first network slice subnet;
in the case where the first NSSI is present but does not meet the subnet service attribute requirements, step 403 is performed.
Step 403, checking whether the dynamic update flag in the first NSST supports dynamic update of the first NSSI;
if dynamic update is supported, step 404 is performed.
Step 404, sending a first request to the updating apparatus;
it should be noted that, in this step, the identification information corresponding to the first NSST, the first specification identifier, and the first network slice subnet service attribute are sent to the updating apparatus.
Step 405, the updating apparatus acquires all specification information corresponding to the first NSST;
step 406, the updating apparatus obtains the service attribute of the second network slice subnet of the deployed service on the first NSSI created by the first NSST;
step 407, judging whether the second specification in all the specification information meets the requirement of the subnet service attribute;
if the second specification exists, step 408 is performed.
Step 408, returning a judgment result;
the step is mainly to send the identification information of the second specification to the NSSMF entity when judging that the second specification exists.
Step 409, creating a mapping relation between NSI and NSSI;
step 410, updating the first NSSI to a second NSSI by using the identification information of the second specification;
step 411, issuing network slice and instance configuration to NF entity;
step 412, sending information of a second NSSI and service information deployed in the second NSSI to an updating apparatus;
step 413, return the create result to the NSMF/operator.
It should be noted that, in the process of creating a slice subnet under the scenario of sharing the NSSI, at least one embodiment of the present application reduces the scenario of failure in creating the slice subnet due to the NSSI not meeting the requirement, and at the same time, reduces the process of manually updating the NSSI by human intervention and repeatedly creating the slice subnet.
