Problems solved by technology

[0006] The processing capability of a network element in a traditional network is fixed. For the indicators that can be used to measure the performance of a network element, the threshold indicating that the performance and processing capability of the network element is almost saturated is also relatively fixed. However, after the network function is virtualized, the VNF The processing capacity of the VNF will change with the situation of the allocated virtual resources, which requires the ability to reset the relevant performance alarm thresholds after the virtual resources of the VNF change, but there is no relevant technical solution at present

Embodiment 1

[0177] See figure 2 , this embodiment uses EM to implement the update of the VNF performance monitoring threshold, as shown in the figure, the process of this embodiment includes:

[0178] Step 110, the EM receives the threshold policy of the VNF performance monitoring threshold sent by the NM or OSS;

[0179] Step 120, the EM obtains information related to virtual resources after the VNF has been scaled;

[0180] In this step, the EM may receive information related to the VNF's scaled virtual resources sent by the VNFM or the VNF. VNF scaling refers to VNF expansion or contraction.

[0181] Step 130, the EM sets a new performance monitoring threshold for the VNF according to the threshold policy and related information about the VNF's scaled virtual resources; wherein, the performance monitoring threshold includes a scaling threshold and / or a performance alarm threshold .

[0182] In this embodiment, the virtual resource related information includes virtual resource capa...

Embodiment 2

[0185] See image 3 , this embodiment uses EM to implement the update and scaling judgment of the VNF performance monitoring threshold, as shown in the figure, the process of this embodiment includes:

[0186] Step 210, the EM receives the threshold policy of the VNF performance monitoring threshold sent by the NM or the OSS, the initial VNF performance monitoring threshold and the monitored performance measurement items;

[0187]The performance monitoring threshold in this embodiment includes at least a scaling threshold, and the scaling threshold includes an expansion threshold and / or a contraction threshold. The performance monitoring threshold may also include a performance monitoring threshold, and the performance monitoring threshold may be equal to the extended threshold in value.

[0188] The above-mentioned monitored performance measurement items may be different according to different VFNs, such as the number of calls, the number of bytes per second, and so on. The...

Embodiment 3

[0203] See Figure 4 In this embodiment, the VNF virtual resource performance monitoring is completed through cooperation of the VNFM and the EM. Among them, the EM implements the update and alarm of the VNF performance alarm threshold, and the VNFM performs scaling judgment and update of the scaling threshold. As shown in the figure, the process of this embodiment includes:

[0204] Step 310: The EM receives the threshold policy of the VNF performance alarm threshold sent by the NM or OSS, the initial performance alarm threshold and the information of the monitored performance measurement items; the VNFM receives the threshold policy of the VNF scaling threshold and the initial scaling threshold sent by the NM or OSS ;

[0205] The EM may obtain the above information from the message of creating performance alarm threshold monitoring sent by the NM or OSS.

[0206] Step 320, the EM instructs the VNF to measure the monitored performance measurement item, and sends the measu...

Abstract

The invention relates to a virtualised network function performance monitoring method and a corresponding system. The method includes the following steps that: a network element manager (EM) receives the threshold value strategy of a VNF (virtualised network function) performance monitoring threshold value which is sent by a network manager (NM) or an operation support system (OSS); the EM obtains relevant information of virtual resources after VNF extension and contraction; and the EM sets a new performance monitoring threshold value for the VNF according to the threshold value strategy and the relevant information of the virtual resources after VNF extension and contraction, wherein the new performance monitoring threshold value includes an extension and contraction threshold value and / or a performance alarm threshold value. With the virtualised network function performance monitoring method and the corresponding system of the invention adopted, the monitoring threshold value of performance can be dynamically adjusted according to the resource condition of the virtualised network function, and resource allocation can be carried out more effectively, and performance threshold value warning can be decreased.

Description

technical field [0001] The present invention relates to the field of mobile communication network management, and more specifically, to a method for monitoring the performance of a virtual network function (VNF: Virtualized Network Function) and a corresponding system. Background technique [0002] In mobile communication networks, operators evaluate network quality, network or service resource utilization, and network processing capabilities through the analysis of performance measurement data. When the performance measurement value exceeds the preset threshold value of the measurement, a corresponding notification containing performance alarms will be reported to the operator, so that the operator can take corresponding measures in time to prevent serious failures or even paralysis of the network. [0003] After network functions are virtualized, the network management architecture and mechanism have some changes. The management architecture after network function virtuali...
