Description

Performance management method and device for network slicing instance

technical field

The present invention relates to the field of wireless communication, in particular to a method and device for performance management of a network slice instance in a wireless communication system.

Background technique

With the rapid development of wireless communication technology, the fifth generation (5th Generation; 5G for short) wireless communication technology has become a hot spot in the industry at present. 5G will support diverse application requirements, including support for higher-speed experience and greater bandwidth access capabilities, lower latency and highly reliable information interaction, and access to larger-scale and low-cost machine-type communication devices. entry and management, etc. In addition, 5G will support various vertical industry application scenarios such as Internet of Vehicles, emergency communications, and industrial Internet. Faced with these performance requirements and application scenarios of 5G, 5G networks need to be closer to the specific needs of users, and their customization capabilities need to be further improved.

To this end, 5G introduces the important concept of network slicing. A network slice is a combination of multiple network functions and corresponding resources that implement communication services. The 5G network consists of various network slices that meet different connectivity capabilities. A network slice is a logical network that meets the communication service requirements of a class or a use case. Figure 1 shows the 5G network scenario after introducing the concept of network slicing, which includes critical machine type communication (Critical Machine Type Communication; referred to as Critical MTC), large-scale machine type communication (Massive Machine Type Communication; referred to as MassiveMTC) and mobile broadband (Mobile Broad Band; MBB for short) communication of three use cases. As shown in Figure 1, the 3GPP operator network can include key machine-type communication network slices, large-scale machine-type communication network slices, and mobile broadband network slices, where each network slice serves communication services for different use cases.

A unified network platform, using dynamic and secure network slicing to support communication services with different functions and service quality requirements, is one of the basic capabilities of 5G networks. A logical network formed by a network slice is implemented through the network slice instance, that is, a network slice is formed by instantiating each network function and corresponding resources of the network slice. To ensure the normal operation of network slicing, 5G networks need to manage the performance of network slicing instances. How to manage the performance of network slice instances, there is no proper solution yet.

The technical solution of the present invention will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

As a key feature of 5G, the 5G network can be divided into multiple network slices. A network slice (NetworkSlice; NS for short) corresponds to a logical network, and the logical network is used to meet a communication service requirement of a use case. A network slice consists of one or more network functions (Network Function; NF for short), and is realized through a Network Slice Instance (NSI for short), that is, by instantiating each network function of a network slice and corresponding resources and configuration to form a network slice. A network slice may include one or more network slice instances, and different network slice instances may have different network functions and/or resource configurations. The performance management of network slice instances is one of the key technologies to ensure the normal operation of 5G networks.

Fig. 2 shows a schematic diagram of a possible network management architecture. As shown in Figure 2, the network function architecture is divided into three levels. Located at the bottom layer is a network element (Network Element, NE for short), which may include core network equipment, access network equipment, and user equipment. The core network equipment may include Mobility Management Entity (MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (PDN-GW for short), etc.; Equipment can include various forms of base stations, such as macro base stations, micro base stations, relay stations, access points, etc.; user equipment can include smart phones, mobile communication terminals, Internet of Things terminals, wireless meter reading devices, etc. Located in the middle layer is an element management system (Element Management System; EMS for short), which may include a domain manager (Domain Manager; DM for short) and an element manager (Element Manager; EM for short). The EM provides the network element management function for managing one network element or a class of network elements with the same type. For example, one EM can manage one or more base stations. EM can exist independently of the network element being managed, and can also be built in the network element being managed. DM can provide network element management function and/or domain management function. A domain managed by the DM may be a collection of multiple network elements of the same type provided by an equipment provider, such as access network equipment provided by an equipment provider. The uppermost layer is a network management system (Network Management System; NMS for short), which may include a network manager (Network Manager; NM for short), for managing network devices provided by different regions and different device providers. Wherein, the NM of the NMS and the DM/EM of the EMS communicate through a northbound interface (Interface N; Itf-N for short).

Currently, the network performance management of the 3GPP mobile communication system is defined by the technical specification TS32.4xx series of standards, and the main standardized interface is the Itf-N interface between the NMS and the EMS. The NMS interacts with the EMS through the Itf-N interface for performance management. Performance management usually includes performance measurement and performance monitoring. For example, for performance measurement, its workflow mainly includes: the NMS creates a measurement job (createMeasurementJob) to the EMS through the Itf-N interface, and the input parameters of the above-mentioned created measurement job may include the NE type to be measured (iOCName), and the NE instance to be measured List (iOCInstanceList), measurement type list (measurementCategoryList), measurement time granularity (granularityPeriod), time interval for sending measurement reports (reportingPeriod), start time of measurement task (startTime), end time of measurement task (stopTime), measurement task plan (schedule), and the priority of the measurement task, etc.; after the EMS receives the created measurement task, it creates a specific measurement task to the NE according to the corresponding measurement task, and returns the output parameters of the created measurement task to the NMS, wherein the above output parameters It may include a measurement job identifier (jobId), a measurement type not supported by the network device (unsupportedList), a status of the measurement job (status), and the like. Similarly, for performance monitoring, its workflow mainly includes: NMS creates a threshold monitoring task (createThresholdMonitor) to EMS through the Itf-N interface, which is used to set thresholds for certain measurement types. alarm. The above input parameters for creating a monitoring task may include the type of network element to be monitored (iOCName), the list of network element instances to be monitored (iOCInstanceList), the threshold information list of the measurement type (thresholdInfoList), and the time interval for reading the threshold (monitorGranularityPeriod) etc.; after the EMS receives the creation threshold monitoring task, it creates a specific threshold monitoring task to the NE according to the corresponding threshold monitoring measurement task, and returns the output parameters of creating the threshold monitoring task to the NMS, wherein the above output parameters may include the threshold monitoring task identifier (monitorId ), the measurement type (unsupportedList) that the network device does not support threshold monitoring, and the status (status) of the threshold monitoring task.

In 5G networks, the introduction of network slicing technology makes network elements in the network management architecture no longer limited to traditional network elements, but also includes network functions. The network function is a processing function for implementing communication, which may be a physical network function (Physical Network Function; PNF for short) or a virtual network function (Virtualized Network Function; VNF for short). For example, a PNF may include a base station; a VNF may include a core access and mobility management function (Core Access and Mobility Management Function; AMF for short), a session management function (Session Management Function; SMF for short), and a user plane function (User plane Function; short for UPF), network slice selection function (Network slice selection function; NSSF for short), etc. When the base station adopts the architecture of the centralized control unit and the digital processing unit, the VNF may also include the non-real-time processing function and radio resource management function of the centralized control unit of the base station. The PNF may be implemented using dedicated hardware; the VNF may be implemented in the form of a virtual machine on a general hardware platform such as a Network Function Virtualization Infrastructure (Network Function Virtualization Infrastructure, NFVI for short). In addition, a Network Slice Manager and Orchestrator (NSM&O for short) module is introduced into the NMS. NSM&O includes the network slice management function, which can be built into the existing NM or exist as an independent NM device. The main role of NSM&O is to realize the management and orchestration of network slices, including network slice lifecycle management, network slice performance management, and network slice fault management. In addition, the introduction of network slicing technology enables EMS to support network slicing, such as being able to perceive the identification of network slicing instances. The introduction of network functions makes EMS need to have the ability to manage network functions. Correspondingly, at the network element management system layer of the network management architecture, there is a corresponding network function management entity (such as a network function manager). This functional entity can exist independently of DM/EM, or can be The function way implements the role of network function management on DM/EM.

Fig. 3 shows a schematic diagram of a possible correspondence between network slice instances and network functions. As shown in Figure 3, network slice instance 1 is composed of network function 1 to network function 4 and the resources and configuration used by each function; network slice instance 2 is composed of network function 5 to network function 8 and the resources and configuration used by each function Composition; network slice instance 3 is composed of network function 7 to network function 12 and the resources and configuration used by each function. Among them, any one of network function 1 to network function 6 and network function 9 to network function 12 is dedicated to a network slice instance, which is called a dedicated network function; network function 7 and network function 8 are composed of multiple network functions Instance shared use, known as shared network functionality.

An end-to-end network slicing instance may span multiple domains, such as covering different equipment forms and products of multiple equipment vendors. Therefore, a network slice instance in an actual network may be divided into different domains for performance management. In addition, the division of domains is not limited to specific scopes and scenarios, for example, dedicated network functions and shared network functions may respectively belong to different domains. When a network slice instance spans multiple domains, the sum of network functions and corresponding resources in any domain of a network slice instance is called a network slice instance subnet of the network slice instance. Different network slice instance subnets can share one or more network functions. Combining the network slicing instance and the network slicing function shown in FIG. 3 , FIG. 4 shows a schematic diagram of a possible network slicing instance subnet. As shown in Figure 4, there is no subnet in network slicing instance 1, and the network slicing function 1 to network slicing function 4 used by it are not divided into different subnets; a possible situation is that network slicing instance 1 The included network functions and resources are provided by an equipment vendor. Network slice instance 2 consists of network slice instance subnet 1 and network slice instance subnet 2, where network slice instance subnet 1 includes network function 5 and network function 6, and network slice instance subnet 2 includes network function 7 and network function 8 ;Network slice instance 3 consists of network slice instance subnet 2 to network slice instance subnet 4, where network slice instance subnet 2 is a network slice instance subnet shared with network slice instance 2, and network slice instance subnet 3 includes network Function 9 and network function 10, network slice instance subnet 4 contains network function 11 and network function 12.
