[0003] Network slicing is an important end-to-end key technology newly introduced by the 5th Generation Mobile Communication Technology (5G) network. It is a method of constructing a network as needed, which enables an operator to divide multiple virtual end-to-end networks on a unified infrastructure.

MODE FOR CARRYING OUT THE INVENTION

[0024] In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure more clear, a detailed description will be given below with reference to the drawings and specific embodiments.

[0025] In the enableable network architecture shown in FIG. 1, a slice enableable server (NSCE-S) and a slice enableable client (NSCE-C) are defined. With the introduction of the enableable layer, control and management capabilities of network slices are provided to the application client side and server side in the vertical industry, meeting the monitoring, management, and control requirements of vertical industry clients for slices. Here, the slice enableable client (NSCE-C) is arranged on the terminal side, and optionally, the slice enableable server (NSCE-S) can be arranged on the industry client side. The slice enableable server can invoke 5G network capabilities via the N33 / N5 interface and can invoke slice lifecycle management, network metric monitoring, and configuration update capabilities via the NSCE-OAM interface. NSCE-S belongs to the Service Enabler Architecture Layer for Verticals (SEAL) and is one of the functional modules therein. The Application Server (AS) can integrally invoke the underlying network slice-related capabilities via NSCE-S.

[0026] As shown in FIG. 2, the embodiment of the present disclosure provides a slice coordination method across the network applied to the slice enableable server NSCE-S, and the method may include the following steps 201 to 203.

[0027] In step 201, a first request sent from the application server is received, and an identifier of a first application is attached to the first request. In step 202, based on the first request, non-public network NPN slice information corresponding to the first application and specific slice information corresponding to the first application in the Public Land Mobile Network (PLMN) are obtained.

[0028] In step 203, service performance monitoring and / or slice resource optimization is performed on the first application based on the NPN slice information and the specific slice information in the PLMN. According to the slice coordination method across networks according to the embodiments of the present disclosure, slice management across networks (such as network performance, monitoring of network status, resource management and optimization, etc.) can be realized, and a unified application programming interface (API) call interface is provided for industry clients, thereby enabling overall management, status monitoring and resource optimization among multiple slices in a multi-network scenario. Here, the industry application synchronously manages and monitors slices across networks through the network capabilities provided by the NSCE-S. Optionally, the NSCE-S can be deployed in a sunken campus or a centralized deployment method can be selected, but it is not specifically limited here.

[0029] As a selectable embodiment, the system of the slice coordination method application across networks according to the embodiments of the present disclosure may specifically include the following 1) to 5). 1) Application server: A vertical industry commercial application server capable of providing services to clients. 2) Slice enable server (NSCE-S): It can play the role of an Application Function (AF), call the 5G core network capabilities, and provide the 5G core network (5GC) network capability open function to the application server as a unified interface. Optionally, it can be centrally deployed within the user domain or distributed across each campus. Optionally, it can also be deployed within the operator domain and function as an overall capability call interface for the operator network. 3) Non-Public Network (NPN): A specific non-public 5GC network for industrial users. The NSCE-S can obtain network execution data via the Network Exposure Function (NEF) element or the Operation Administration and Maintenance (OAM) in the non-public network. 4) Slice-Enabled Client (NSCE-C): It is arranged in the enabling layer client of the industrial terminal, can be registered with the NSCE-S, and can report information such as application performance data and location data to the NSCE-S. 5) Vertical Application Layer Client (VAL-C): It is arranged on the industrial application client side of the terminal and requests the invocation of the services of the network-side application server.

[0030] In at least one embodiment of the present disclosure, the NPN slice information includes NPN slice performance information and / or NPN slice status information, and / or the specific slice information of the PLMN includes slice performance information and / or slice status information.

[0031] As an optional embodiment, before step 202, the method further includes checking whether the first application is a permitted user and whether the first application is permitted to initiate the first request, Correspondingly, step 202 includes when the first application is a permitted user and the first application is permitted to initiate the first request, based on the first request, obtaining the NPN slice information corresponding to the first application and the specific slice information corresponding to the first application in the PLMN.

[0032] In one alternative embodiment of the present disclosure, the first requirement includes a business service quality (Quality of Service, QoS) monitoring requirement. That is, for industry applications implemented across the network, based on the business experience (e.g., Quality of Experience, QoE) of the end-user application layer and the QoS data across the network, comprehensive monitoring and analysis integration are performed to provide a mechanism for realizing global end-to-end performance monitoring.

[0033] In another alternative embodiment of the present disclosure, the first requirement includes a business resource optimization requirement. That is, for industry applications implemented across the network, based on the multi-network slice state information, a dynamic adjustment and adjustment mechanism for resource allocation of the slice across the network is realized. The service quality service level protocol (Service-Level Agreement, SLA) of the network slice allocates resources based on a general template during the initial deployment process. However, the business experience of each terminal actually in use is comprehensively determined by various factors such as the signal coverage of the terminal's location area, user distribution density, and business model. Thus, there may be a situation where congestion occurs in some areas while resources are idle in some areas. Therefore, the embodiments of the present disclosure can optimize the resource utilization rate by realizing the dynamic adjustment of the resource allocation of the slice across the network (public and private) for a certain industry client through the business resource optimization requirement.

[0034] As one selectable embodiment, when the first requirement includes a business service quality QoS monitoring requirement, the business QoS monitoring requirement includes the network identifier of the slice deployment, the application server identifier, the performance indicator to be monitored, the time period, and at least one of the monitoring areas. Correspondingly, step 202 is Mapping the identifier of the first application as a slice identifier; Obtaining NPN slice performance information and specific slice performance information in a PLMN based on the slice identifier. Optionally, the method further includes: Sending a data acquisition request to a slice-enabled client NSCE-C, where the data acquisition request is used to request the acquisition of application performance data of a first application; Receiving a data acquisition response sent from NSCE-C, where the data acquisition response is accompanied by the application performance data of the first application. Correspondingly, step 203 includes: Performing data analysis and integration on the NPN slice performance information, specific slice performance information in the PLMN, and the application performance data of the first application to generate a user performance quality report; Sending a service QoS monitoring response to the application server based on the user performance quality report. The service QoS monitoring response includes: A specified time period; A specified area; The end-to-end time delay of the terminal; The uplink and downlink speeds of the terminal; At least one of the terminal user sensing indicators.

[0035] [Example 1] As shown in FIG. 3, it includes the following steps 1 to 8. In step 1, the application server sends a service quality monitoring request (including contents such as the network identifier (NetworkID) of the slice configuration, the application server identifier, the application identifier (Identification, ID), the performance indicators specifically monitored, the time period, and the monitoring area) to NSCE-S. In step 2, when receiving a request, NSCE-S checks whether the application is a permitted user and whether the application is permitted to start slice monitoring requests. If the execution of the operation by the application is not permitted, NSCE-S returns a failure response. In step 3, NSCE-S maps based on the received application ID as a slice identifier and obtains NPN slice performance (such as throughput, time delay, etc.) information.

[0036] In step 4, NSCE-S maps based on the received application ID as a slice identifier and obtains specific slice performance (such as the number of real-time access people, throughput, time delay, etc.) information in the PLMN (Public Land Mobile Network). In step 5, optionally, NSCE-S sends a data acquisition request, such as an application performance data (such as terminal QoE data of a specific application) request, to the user equipment (UE) (NSCE-C). In step 6, optionally, NSCE-C responds to the data acquisition request to NSCE-S.

[0037] In step 7, NSCE-S performs data analysis and integration based on the performance and network status information obtained from the network side and the QoE information (optional) reported from the UE side, and extracts the user performance quality report. In step 8, NSCE-S notifies the application server of the response to the slice-specific application ID service QoS monitoring request (such as the end-to-end time delay of the UE, the uplink and downlink speeds of the UE, the terminal user sensing index, etc. within a specified time period and specified area).

[0038] As another alternative embodiment, the first request includes a service resource optimization request, and the service resource optimization request includes the network identifier of the slice configuration, and An application server identifier, and An indicator for which optimization is expected, and An area for which optimization is expected, and includes at least one of them. Correspondingly, step 202 includes Mapping the identifier of the first application as a slice identifier, and Based on the slice identifier, obtaining NPN slice state information and specific slice state information in the PLMN.

[0039] Correspondingly, step 203 includes Performing an optimization analysis based on the NPN slice state information and the specific slice state information in the PLMN to dynamically adjust the shared resource allocation (for example, radio resources) between slices and generate an optimization analysis result; and Based on the optimization analysis result, sending a first lifecycle management request to the NPN element and / or sending a second lifecycle management request to the PLMN element, where a service profile of the NPN slice updated in the first lifecycle management request is attached, and a service profile of a specific slice of the PLMN updated in the second lifecycle management request is attached; and Receiving a first lifecycle management response sent from the NPN element and / or receiving a second lifecycle management response sent from the PLMN element, where a slice resource adjustment result is attached to the first lifecycle management response and / or the second lifecycle management response; and Based on the slice resource adjustment result fed back from the NPN element and the slice resource adjustment result fed back from the PLMN element, sending a service resource optimization response to the application server.

[0040] [Example 2] As shown in FIG. 4, it includes the following steps 1 to 10. In step 1, the application server sends a business resource optimization request (including contents such as the network identifier NetworkID of slice placement, application server identifier, application ID, indicators expected to be optimized, and areas of optimization, etc.) to NSCE-S. In step 2, upon receiving the request, NSCE-S checks whether the application is a permitted user and whether the application is permitted to initiate a business resource optimization request. If the execution of this operation by the application is not permitted, NSCE-S returns a failure response. In step 3, NSCE-S maps it as a slice identifier based on the received application ID and obtains the slice state (such as resource utilization rate) information of the NPN network.

[0041] In step 4, NSCE-S maps it as a slice identifier based on the received application ID and obtains the specific slice state (such as resource utilization rate) information in the PLMN network. In step 5, NSCE-S performs an optimization analysis based on the received application ID, the obtained states of the PLMN and NPN networks (such as resource utilization rate, etc.) and the previously obtained user performance quality report (optional) information (for example, dynamically adjusts the sharing of radio resources between slices based on the user distribution model and the current usage status of network resources). In step 6, based on the optimization analysis result, NSCE-S sends the slice lifecycle management ModifyNsi (that is, MODIFYNSI) request information to the corresponding NPN network, which includes the updated service profile (ServiceProfile) corresponding to the slice. Here, ModifyNsi means the modification of Nsi.

[0042] In step 7, the NPN network returns a ModifyNsi response result. In step 8, based on the optimization analysis result, NSCE-S sends the slice lifecycle management ModifyNsi request information to the corresponding PLMN network, which includes the updated ServiceProfile corresponding to the slice. In step 9, the PLMN network returns the ModifyNsi response result.

[0043] In step 10, based on the resource adjustment results fed back from the NPN and the PLMN network, NSCE-S returns a service resource optimization response to the application server. From the above, the embodiments of the present disclosure can realize the collaborative management operation between industrial application multi-network slices (including NPN network slices and specific slices in the public network) by using an enable network server, and can provide a unified service call interface for industrial clients. It can provide a global view of network slice performance monitoring across multi-type networks for the same application, and improve the operation and management efficiency in a multi-network scenario based on user management. At the same time, by comprehensively considering the service experience QoE and network QoS data of the terminal user application layer, comprehensive monitoring and analysis integration are performed, which is beneficial to improving the service experience of terminal users. It can dynamically adjust the resource allocation of slices across the network applied to the slice enable server NSCE-S, avoid the situation where the network resource allocation between slices deployed for the same industrial client becomes unbalanced, and optimize the resource utilization rate.
