Detailed Description

First, a description will be given of several concepts of network slices, network slice instances, network slice subnet instances, and network functions related to embodiments of the present invention. The network instances described in embodiments of the present invention include at least one of network slice instances, network slice subnet instances, and network functions.

Network Slice (NS) refers to different logical networks that are customized according to different service requirements. The network slice may be a complete end-to-end network comprising the terminal, the access network, the transport network, the core network and the application server, capable of providing complete telecommunication services, with certain network capabilities. The network slice may also be any combination of the above terminals, access networks, transport networks, core networks and application servers.

A Network Slice Instance (NSI) is an instantiation of an NS, that is, a real-running logical Network, and can meet certain Network characteristics or service requirements. One network slice instance may provide one or more services. The network slice instance can be created by a network slice management function device, and one network slice management function device can create a plurality of network slice instances and manage the network slice instances simultaneously, including performance monitoring, fault management and the like during the operation of the network slice instances. When a plurality of network slice instances coexist, part of network resources and network functions can be shared among the network slice instances. The network slice instance may or may not be created from a network slice template. A complete Network Slice Instance is capable of providing a complete end-to-end Network service, and what constitutes the Network Slice Instance may be a Network Slice Subnet Instance (NSSI) and/or a Network function. The network functions may include physical network functions and/or virtual network functions. Hereinafter, a physical network function and/or a virtual network function are collectively referred to as a network function.

One network slice example can be divided into a plurality of network slice subnet examples, so that the network management system can be managed conveniently. The network slice subnet instance may not need to provide complete network service end to end, and the network slice subnet instance may be a set formed by network functions of the same equipment provider in the network slice instance, or may be a set formed by network functions divided by domains, such as a core network slice subnet instance, an access network slice subnet instance, or a set formed by other manners, such as a deployment location. A network slice subnet instance may be shared by multiple network slice instances. A network slice instance may consist of several network slice subnet instances, each consisting of several network functions and/or several network slice subnet instances. A network slice instance may consist of several network slice subnet instances and network functions that are not partitioned into network slice subnet instances. A network slice instance may also consist of only a few network functions.

Network Function (NF) is a processing function in a Network that defines the behavior and interfaces of functionality. The network function may be implemented by dedicated hardware, by running software on dedicated hardware, or in the form of a virtual function on a general hardware platform. Thus, from an implementation point of view, network functions may be divided into physical network functions and virtual network functions. From a usage perspective, network functions can be divided into dedicated network functions and shared network functions. In particular, for multiple network slice instances/network slice subnet instances, different network functions, referred to as dedicated network functions, may be used independently, or the same network function may be shared, referred to as shared network function.

Fig. 1 is a schematic diagram of a network system according to an embodiment of the present invention.

The communication service management function device 101 is further configured to obtain management data (such as performance data, fault data, and the like) of the network instance from the network slice management function device 102, and generate management data of the communication service running on the network slice instance. The fault data comprises alarm data, and in the embodiment of the invention, the alarm data is equivalent to the alarm information. The communication service management function device 101 may also receive a subscription requirement of the operator and/or a third party customer for the network slice management data and/or the management data of the communication service, and the like.

The network slice management function device 102 is mainly responsible for receiving a network slice instance management request sent by the communication service management function device 101.

The network slice subnet management function device 103 is mainly responsible for receiving the network slice subnet instances and/or the network function management requests sent by the network slice management function device 102, managing the network slice subnet instances, arranging the composition of the network slice subnet instances, decomposing the requirements of the network slice subnet instances into the requirements of each network function and/or the nested network slice subnet instances, and sending the nested network slice subnet instance management requests to other network slice subnet management function devices 103. Nested means that one network slice subnet instance may be composed of one or more network slice subnet instances.

The communication service management function device 101 and the network slice management function device 102 have an interface 1, and the network slice management function device 102 and the network slice subnet management function device 103 have an interface 2. Wherein, the interface 1 is used for the communication service management function device 101 to send a network slice instance management request to the network slice management function device 102. The interface 1 is also used for the network slice management function device 102 to feed back the management request execution result to the communication service management function device 101. The interface 1 is also used for the network slice management function device 102 to report management data to the communication service management function device 101. The interface 2 is used for the network slice management function device 102 to send a network slice subnet instance management request and/or a network function management request to the network slice subnet management function device 103. The interface 2 is also used for the network slice subnet management function device 103 to feed back the management request execution result to the network slice management function device 102. The interface 2 is also used for the network slice subnet management function device 103 to report management data to the network slice management function device 102.

It should be noted that the communication service management function device 101, the network slice management function device 102, the network slice subnet management function device 103, the interface 1, and the interface 2 may also have other names, and the embodiment of the present invention is not limited in particular. In the embodiment of the present invention, the communication service management function device 101, the network slice management function device 102, and the network slice subnet management function device 103 are named according to functions, and in a specific application, the communication service management function device 101 may be any device having a communication service management function, the network slice management function device 102 may be any device having a network slice management function, and the network slice subnet management function device 103 may be any device having a network slice subnet management function.
