As shown in fig. 3, the application instantiation method provided by the embodiment of the present invention may include S101-S106.

S101, CSMF obtains a service level agreement.

It should be understood that the Service Level Agreement (SLA) is agreement information that the user subscribes to the operator and is used for guaranteeing the communication quality of the user.

S102, CSMF determines NST information based on SLA and sends a network slice establishment request to the NSMF.

Wherein, the network slice establishing request includes the Network Slice Template (NST) information and the identifier of the target network slice.

It should be understood that the network slice establishment request is for requesting establishment of the target network slice to satisfy the SLA.

It can be understood that the SLA characterizes the service level that the operator needs to provide to the user, for example, how much uplink and downlink bandwidth needs to be satisfied, and how many milliseconds (ms) the delay needs to be within. However, how to deploy the relevant devices used by the target network slice, and the resource conditions of the relevant devices need to be embodied in the NST information. For example, the network route corresponding to the target network slice needs to pass through which network elements and base stations, and how many computing resources and storage resources need to be allocated to the network elements and the base stations.

Alternatively, the NST information may be an Excel file.

S103, the NSMF receives the network slice establishment request sent by the CSMF.

In connection with the above description of the embodiments, it should be understood that the network slice establishment request includes the NST information and an identification of the target network slice.

S104, the NSMF determines first NSST information based on the NST information.

Wherein the first NSST information is NSST information of a first subnet slice, and the first subnet slice is one of a plurality of subnet slices corresponding to the target network slice.

It is to be understood that the NSMF may determine the first NSST information from the NST information based on the first sub-network slice (which may specifically be an identification of the first sub-network slice).

S105, the NSMF sends a sub-network slice establishment request to the core network NSSMF.

Wherein the sub-network slice setup request includes the first NSST information and an identification of the first sub-network slice.

It should be understood that the sub-network slice establishment request is for requesting establishment of the first sub-network slice. In this case, the first subnetwork slice may be understood as a subnetwork slice corresponding to the core network NSSMF.

In an implementation manner of the embodiment of the present invention, the communication system may further include an access network NSSMF and a transmission network NSSMF. After receiving the network slice establishment request, the NSMF may further determine other NSST information (i.e., NSST information corresponding to the access network NSSMF and the transmission network NSSMF) based on the NST information, and send an establishment request of a corresponding sub-network slice to the access network NSSMF and/or the transmission network NSSMF.

S106, the core network NSSMF receives the subnet slice establishment request sent by the NSMF.

To this end, the core network NSSMF may acquire the first NSST information.

As shown in fig. 4, the application instantiation method provided by the embodiment of the present invention may further include S201 to S209.

S201, a core network NSSMF sends an NSD creation request to the NFVO.

Wherein the NSD creation request includes first NSST information, the first NSST information being NSST information of a first subnet slice.

It should be understood that the NSD creation request is for requesting the NFVO to create or generate NSD information for the first subnetwork slice.

Optionally, the NSSMF may send the NSD creation request to the Nfvo through the Os-Ma-Nfvo interface.

S202, the NFVO receives an NSD creation request sent by the core network NSSMF.

S203, the NFVO generates NSD information of the first subnet slice based on the first NSST information and the VNFD.

Specifically, the NST information and the first NSST information are languages that can be recognized or read by the user. After receiving the first NSST information, NFVO may convert the first NSST information into machine language in conjunction with the VNFD, i.e., may obtain NSD information of the first subnet slice.

It should be understood that the VNFD may be understood as a predetermined template, and the NFVO may populate the template with the content or parameters included in the first NSST information to generate the NSD information.

It is to be appreciated that the NSD information is used to characterize the deployment of the first subnetwork slice. Specifically, which network elements in the core network are used by the first subnetwork slice during the deployment process, where the locations of the network elements are located, what Internet Protocol (IP) addresses of the network elements are, and the like.

S204, the NFVO sends the NSD information of the first sub-network slice to the MEAO.

To this end, the measo may receive the NSD information of the first subnet slice sent by the NFVO.

Optionally, the NFVO may send the NSD information to the MEAO through an Mv1 interface

S205, the core network NSSMF sends an installation package of the MEC application to the MEAO.

It should be understood that the MEC application is an application deployed on the MEC platform (or MEC system), and the core network NSSMF sends an installation package of the MEC application to the MEC, so that the MEC application can be installed by the MEC application, thereby completing the instantiation process of the MEC application in the relevant device.

Optionally, the core network NSSMF may send the installation package of the MEC application to the MEAO through an Mm1 interface.

It should be noted that the execution sequence of S201 and S205 is not limited by the embodiment of the present invention. For example, S201 may be performed first and then S205 may be performed, or S205 may be performed first and then S201 may be performed, or S201 and S205 may be performed simultaneously.

S206, the MEAO receives an installation package of the MEC application sent by the core network NSSMF and receives NSD information of the first sub-network slice sent by the NFVO.

The NSD information is used to characterize a deployment situation of the first sub-network slice, the NSD information is generated by the NFVO based on first NSST information and VNFD, the first sub-network slice is a sub-network slice corresponding to the MEC application, and the first NSST information is NSST information of the first sub-network slice.

S207, the installation package of the MEC application is installed by the meco to generate first description information of the MEC application, and the NSD information of the first subnetwork slice is added to the first description information of the MEC application to generate second description information of the MEC application.

It should be understood that the first description information is an installation package description file of the MEC application, and is an image description file.

In an implementation manner of the embodiment of the present invention, the first description information includes a first field and a second field, where the first field is used to characterize a traffic type to be offloaded corresponding to the MEC application, and the second field is used to characterize a service type corresponding to the MEC application.

For example, the offload traffic type may include uplink and downlink traffic, bandwidth, etc.; the service type corresponding to the MEC application may be a positioning service, a Radio Network Information Service (RNIS), and the like.

Alternatively, the first field may be an appprafficrule field and the second field may be an appServiceRequired field.

Specifically, the meco adds the NSD information of the first sub-network slice to the first description information of the MEC application, that is, adds a Virtual Network Function (VNF) of a core network element referenced by the first sub-network slice and a designed r (an) list to the first description information. Thus, the second descriptor covers the VNF and r (an) list.

In an implementation manner of the embodiment of the present invention, the NSD information includes location information of a plurality of core network elements, IP addresses of the plurality of core network elements, and identifiers of a plurality of base stations.

It should be understood that the plurality of core network elements are core network elements corresponding to the first subnetwork slice, and the plurality of base stations are base stations serving the first subnetwork slice.

Illustratively, the plurality of core network elements may be a User Plane Function (UPF), a Session Management Function (SMF), and a mobility management function (AMF), among others. The location information of a core network element may characterize which area of which city the core network element is located in, etc.

The plurality of base stations may also be understood as base stations that allocate resources for the first sub-network slice.

S208, the MEAO sends a resource allocation request to the VIM.

Wherein the resource allocation request includes an identification of the MEC application and an identification of the first subnetwork slice, the resource allocation request requesting allocation of infrastructure resources for the MEC application.

It will be appreciated that the resource allocation request is also used to inform the VIM of the specific deployment location of the MEC application, i.e., on which server the specific deployment is.

After the VIM allocates infrastructure resources for the MEC application, Network Slice Instance (NSI) information of the first subnetwork slice may be obtained, where the NSI information is a result of instantiation of the NSD information.

In an implementation manner of the embodiment of the present invention, the MEAO may also send the information included in the first field, the information included in the second field, and the lifecycle management information of the MEC application to a mobile platform manager (MEPM), and then the MEOM sends the resource allocation request to the VIM.

S209, the MEAO sends an application program instantiation request to the target device.

Wherein the application instantiation request comprises second description information of the MEC application, and the application instantiation request is used for requesting to instantiate the MEC application.

To this end, the deployment process of the MEC application may be completed in the target device (e.g., a certain server).

The technical scheme provided by the embodiment can at least bring the following beneficial effects: as known from S201 to S209, the core network NSSMF may send an NSD creation request to the NFVO, and then the NFVO may send the generated NSD information of the first sub-network slice to the measo; the core network NSSMF may also send an installation package of the MEC application to the meco, and then install the installation package after the meco receives the installation package of the MEC application to generate the first description information of the MEC application; the meco then adds the NSD information to the first description information to generate second description information of the MEC application, and sends an application instantiation request to the target device, that is, requests to instantiate the MEC application, specifically, completes the deployment process of the MEC application.
