Embodiment 5
[0235] Embodiment 5 mainly describes the registration process of management service instances of NS and NSS. Embodiment 6 of this application mainly describes the query process of operation and maintenance management service instances. Figure 8 The signaling flow chart of the management method of the NS management service instance provided in Embodiment 6 of the present application, as shown in Figure 8 As shown, the method provided in this embodiment includes the following steps:
[0236] Step S601, the CSMF instance receives an operation and maintenance management service request.
[0237] The operation and maintenance management service request is used to request the operation and maintenance management of NSI. The operation and maintenance management service request includes: management plane service type, NSI ID, NSI coverage location information and requested data information, wherein the management plane service type It is the operation and maintenance manage...
example 22
[0329] Optionally, the MSRF instance 22 is also used for:
[0330] Receiving a query request sent by the query device, the query request includes a query identifier of the management service instance, and the query identifier includes: the identifier of the network slice instance, the service type of the management plane, and the management domain information of the network slice;
[0331] Querying the identifier of the management service instance according to the query identifier;
[0332] Sending a query response to the query device, where the query response includes the identifier of the management service instance.
[0333] Wherein, the management service instance 21 may be an LCM service instance of NS, an LCM service instance of NSS, an operation and maintenance management service instance of NS, or an operation and maintenance management service instance of NSS.

Abstract
The present application provides a management method and device for network slicing management service instances, including: the LCM service instance receives an LCM operation request, the LCM operation request includes NSI coverage location information, and the LCM service instance generates an LCM service according to the LCM operation request The management identifier of the instance, the management identifier of the LCM service instance includes the NSI ID, the service type of the management plane, and the management domain information of the NS. The LCM service instance sends a registration request to the MSRF instance, and the registration request includes the management identifier of the LCM service instance. The LCM service instance dynamically generates the management identifier during the creation of the NSI, and registers the management identifier of the LCM service instance in the MSRF instance, and then can query the LCM service instance from the MSRF, which facilitates the management in the service-oriented management plane architecture. NSI conducts LCM management.
Description
technical field [0001] The present application relates to communication technologies, and in particular to a method and device for managing service instances of network slicing. Background technique [0002] With the development of wireless communication technology and the expansion of application scenarios, the services of the fifth generation mobile communication (5th-Generation, 5G) system tend to be diversified. Diversified services have different requirements on network bandwidth, delay, security, and reliability. The 3rd Generation Partnership Project (3GPP) introduced Network Slice (Network Slice, NS). Network slice can be understood as a combination of network functions and resources required to complete a certain (some) business. It is a A complete logical network, different network slices are logically or physically isolated. By creating different network slice instances (Network Slice Instance, NSI) to meet the needs of different business scenarios, network slic...
