Description
Technical Field
The invention relates to the field of communication, in particular to a method, a device and a system for establishing connection by virtual network Element Management (EM).
Background
In a mobile communication network, an operator evaluates the network quality, the utilization rate of network or service resources and the processing capacity of the network through the analysis of performance measurement data, and can also grasp the operation condition of the network in time through carrying out threshold monitoring on the performance data, and when the performance measurement value exceeds a preset threshold value of the measurement, a corresponding notice containing a performance alarm is reported to the operator, so that the operator can take corresponding measures in time to prevent the network from serious faults and even paralysis.
After the network function is virtualized, the network management architecture and mechanism have some changes, and the management architecture after the network function is virtualized is shown in fig. 1, in which: a Network Function Virtualization Orchestrator (NFVO) is responsible for the life cycle management of Network services, the resource scheduling of Network Function Virtualization Infrastructure (NFVI) across a Virtual Infrastructure Manager (VIM), and other Functions. A virtual network function Manager (VNF Manager, abbreviated VNFM) is responsible for lifecycle management of VNFs, each having an associated VNFM. The VIM is responsible for controlling and managing NFVI computation, storage, and network resources. Scaling operations including Scale out \ up and Scale in \ down are arranged in the life cycle of the VNF, and the virtual resources of the VNF can be adjusted.
The traditional Network Management usually adopts a three-layer Management structure including a Network Management (NM) or an Operation Support System (OSS), an Element Management (EM), and an Element. Herein, NM is also referred to as a Network Management System (NMs), and EM is also referred to as an Element Management System (EMs). The interface between the OSS/NM and the EM is a northbound interface and the EM and the network element are southbound interfaces. And the EM completes the configuration of the network element and the acquisition of information such as network element performance, faults, alarms and the like. NM is oriented to network monitoring and analysis of the whole network, and the functions comprise monitoring and operation of network topology, whole network fault warning and acceptance, whole network configuration information acquisition and configuration distribution, end-to-end network performance monitoring and analysis, flow direction and flow distribution monitoring and analysis and the like. After the network function is virtualized, the traditional network manager is responsible for managing the virtual network function application layer.
After network function virtualization, in order to enable full-automatic deployment, network Element Management (EM) also has a virtualization requirement, and when an address of the virtual EM is dynamically allocated after the virtual EM is instantiated, the virtual EM needs to be capable of establishing connection with an NM, otherwise, the NM cannot perform application layer management on a VNF instance managed by the NM through the virtual EM, but a method for establishing connection between the virtual EM and the NM does not exist in the related art.
In view of the above problems, no effective solution has been proposed in the related art.
