In the Management field of wireless communication systems, a Network Management System (NMS) and an Element Management System (EMS) are two important Management systems in a mobile communication Network. The NMS mainly completes a network management layer function in an International Telecommunications Union (ITU) Telecommunications Management Network (TMN), and is responsible for management of all network elements in a managed network. The EMS mainly performs the network element management layer functions in the ITU TMN, i.e. the management functions of one or more mobile communication devices.
At present, in order to improve the flexibility of a communication Network and reduce the management cost, an operator initiates and provides a Network Function Virtualization (NFV) concept, and under the condition of using an NFV technology, original physical Network element equipment is replaced by a Virtualized Network Function (VNF) so that the Network function is decoupled from specific hardware. After network function virtualization is realized, from the application level, when a network service instance is to be established, a VNF instance required by a network service needs to be generated first, and then one or more VNF instances form a network service instance, so that the network service is provided through the network service instance. One benefit of the virtualized network function is that, with the change of the use condition of the network, the resources used by the VNF instances forming the network service can be dynamically adjusted, that is, the VNF instances are scaled, so as to improve the utilization rate of the resources and achieve the purpose of saving energy. For VNF instance scaling, the VNF instance scaling may be triggered automatically by a VNF manager (VNFM) or triggered by a NMS or EMS.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment of the present invention is applicable to energy saving of a virtualized Network, and fig. 1 is a Network function virtualization reference architecture diagram, and as shown in fig. 1, a VNF is isolated from a Network Function Virtualization Infrastructure (NFVI) of a bottom layer. For the management of the VNF, the conventional maintenance management function is performed on the VNF instance through the EMS, and the lifecycle management function of the VNF is completed through the VNFM. The underlying virtual infrastructure is managed by a Virtual Infrastructure Manager (VIM), and specific network traffic is typically accomplished through one or more VNF instances. The management of network traffic is performed by an NFV orchestrator (NFVO).
In the embodiment of the present invention, the expansion and contraction of the VNF instance includes expansion and contraction, where the expansion includes two cases:
extension (scale out): when the VNF can be composed of multiple Virtualized Deployment Units (VDUs), the VDU instances composing the VNF instance are added to increase the capability of the VNF instance;
scale up (scale up): that is, the configuration of a Virtual Machine (VM) running the VNF instance is increased, such as adding a Central Processing Unit (CPU), a memory, a network port, and the like, to increase the capability of the VNF instance;
correspondingly, the shrinkage capacity also includes two cases:
shrinkage (scale in): namely, when the VNF can be composed of multiple VDUs, the VDU instances composing the VNF instance are reduced to reduce the capability of the VNF instance;
scale down: i.e. configuration of the VM running the VNF instance is reduced, such as reducing CPU, memory, network ports, etc., to reduce the capability of the VNF instance.
In various embodiments of the present invention, fig. 2 is a schematic flowchart of a first embodiment of a virtualized network energy saving method provided by the present invention, as shown in fig. 2, an execution main body of the present embodiment is an EMS, energy saving analysis and control functions are located in the EMS, that is, an EMS centralized energy saving, where the method includes:
step 101: and acquiring energy-saving information.
Here, the energy saving information includes: energy saving cells and energy saving triggering conditions.
Specifically, in this step, the EMS acquires energy saving information, where the energy saving information includes: a cell capable of saving energy and an energy saving trigger condition of the energy saving cell. The method for obtaining the energy saving information by the EMS may be: the EMS collects operation data of the network for a certain period of time and analyzes the collected operation data to determine which cells can save energy and energy saving triggering conditions of the corresponding cells, including but not limited to: energy saving time period, traffic thresholds triggering entry and exit of energy saving, etc.
It should be noted that the energy saving period mentioned above refers to a period in which energy saving is possible, that is, the time T1 at which energy saving is started and the time T2 at which energy saving is ended are indicated; the traffic threshold triggering the entering of energy saving refers to a traffic threshold TL1 of a cell which can save energy and a traffic threshold TL2 of a cell for providing coverage for the energy saving cell, and the traffic threshold triggering the exiting of energy saving refers to a traffic threshold TU1 of a cell for providing coverage for the energy saving cell. The traffic threshold TL1 represents the number of users accessing the energy-saving cell, and the value thereof may be set according to the performance of the system and the user requirement, and is not limited herein; TL2 represents the number of cell access users providing coverage for the energy saving cell, and as such, the number can be set according to the performance of the system and user requirements, and is not limited herein, and TU1 is similar.
Step 102: and when the energy-saving cell meets the energy-saving triggering condition, sending an energy-saving instruction to a base station corresponding to the energy-saving cell, wherein the energy-saving instruction is used for controlling the energy-saving cell not to receive service access by the base station.
In this step, when the energy-saving triggering condition of the energy-saving cell is satisfied, the EMS may perform an operation of entering energy saving, that is, the EMS issues a command to the base station corresponding to the cell requiring energy saving, so that the energy-saving cell does not accept new service access. The energy-saving triggering conditions met by the energy-saving cell are as follows: when the traffic of the cell capable of saving energy is less than the threshold TL1 and the traffic threshold of the cell for providing coverage for the energy saving cell is less than TL2, the energy saving cell starts to enter an energy saving state.
Step 103: and when the VNF instance corresponding to the energy-saving cell does not support automatic scaling, controlling the VNFM to scale the VNF instance.
In this step, the EMS checks whether the VNF instance corresponding to the energy-saving cell supports automatic scaling, and when it is determined that the VNF instance corresponding to the energy-saving cell does not support automatic scaling, the EMS issues a command to the VNFM to allow the VNFM to scale the VNF instance corresponding to the cell that needs energy saving, and the scaling can be gradually performed for multiple times to achieve energy saving of the virtualized network.
In the energy saving method for the virtualized network of the embodiment, the EMS sends an energy saving instruction to a base station corresponding to an energy saving cell by acquiring energy saving information and determining that the energy saving cell meets an energy saving trigger condition according to the energy saving information, so that the base station controls the energy saving cell not to receive new service access any more; and further determining that the VNF instance corresponding to the energy-saving cell does not support automatic scaling, and giving a command to the VNFM by the EMS to enable the VNFM to expand the VNF instance corresponding to the cell needing energy saving, so that energy saving of the network is realized. The method is suitable for energy conservation of the virtual network, and solves the problem that the prior art is not completely suitable for the virtual network.
Further, on the basis of the first embodiment, the method further includes: when the energy saving exit condition is satisfied, that is, when the traffic threshold of the cell for providing coverage for the energy saving cell is greater than TU1, the energy saving cell exits the energy saving state, and the EMS performs an operation of exiting energy saving (not shown in fig. 2), including:
EMS sends a command to a base station corresponding to a cell needing energy saving, so that the cell starts to receive new service access;
the EMS checks whether the VNF instance corresponding to the cell needing energy saving supports automatic scaling or not, and if not, the EMS gives a command to the VNFM to perform capacity expansion (gradual expansion) on the VNF instance. During the energy saving process, the EMS needs to monitor the traffic of the cell providing coverage for the energy saving cell, and if the traffic of the coverage cell exceeds the energy saving threshold TU1, the EMS needs to perform exit energy saving operation in advance.
Further, on the basis of the first embodiment, the method further includes:
and if the energy-saving cell has no active service, controlling the base station corresponding to the energy-saving cell to close the radio frequency module corresponding to the energy-saving cell.
Specifically, when a cell requiring energy saving has no active service at all, the EMS instructs the corresponding base station to close the radio frequency module corresponding to the cell; further, if all cells in the base station have no active service, the whole antenna may be turned off.
Further, on the basis of the foregoing embodiment, the acquiring energy saving information includes: collecting operation data of a network within preset time, and analyzing the operation data to obtain energy-saving information; or receiving the energy saving information sent by the network management system NMS.
Specifically, there are two methods for the EMS to obtain the energy saving information, one is that the EMS collects operation data of the network within a preset time, and analyzes the collected operation data to obtain the energy saving information, so as to determine which cells can save energy and energy saving triggering conditions of corresponding cells, where the energy saving triggering conditions include, but are not limited to: energy saving time interval, threshold of traffic triggering entry and exit of energy saving, etc.; the preset time period may be a time period before the current time, for example, a time period calculated from the current time and calculated forward for 5 days, and the preset time period is specifically set according to network performance and user requirements, and is not limited herein; the other is that the EMS does not execute the step of collecting and analyzing, the step of collecting and analyzing is executed by the NMS to obtain energy-saving information, the NMS sends the energy-saving information to the EMS, and the EMS receives the energy-saving information sent by the NMS so as to obtain the energy-saving information.

Step 105: the EMS sends an energy-saving instruction to a base station corresponding to the energy-saving cell, and the energy-saving instruction is used for controlling the energy-saving cell not to receive service access by the base station.
In this step, when the energy saving triggering condition is satisfied, the EMS issues a command to the base station corresponding to the cell that needs to save energy, so that the energy saving cell does not accept new service access any more.
Step 106: the EMS judges whether the VNF instance corresponding to the energy-saving cell supports automatic expansion or not, if not, step 107 is executed; otherwise, step 108 is performed.
In this step, the EMS determines whether the VNF instance corresponding to the energy-saving cell supports automatic scaling; if the VNF instance corresponding to the energy-saving cell does not support automatic scaling, go to step 107, and if the VNF instance corresponding to the energy-saving cell supports automatic scaling, go to step 108.
Step 107: and the EMS controls the VNFM to reduce the volume of the VNF instance.
Step 108: EMS judges whether the energy-saving cell has no active service at all; if yes, go to step 109, otherwise return to step 108 to continue to determine whether the energy-saving cell has no active traffic service at all, until no active traffic service at all, continue to execute step 109.
Step 109: and the EMS controls the base station corresponding to the energy-saving cell to close the radio frequency module corresponding to the energy-saving cell.
The contents of step 107 to step 109 are described in detail in the above embodiments, and are not described herein again.
In this embodiment, step 1011 may also be replaced by:
step 1012: and the NMS collects the operation data of the network within the preset time, and analyzes the operation data to obtain the energy-saving information.
Step 1013: the NMS sends the energy saving information to the EMS.
