detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

The embodiment of the present invention is applicable to the energy saving of the virtualized network. FIG. 1 is a reference diagram of the network function virtualization reference architecture. As shown in FIG. 1 , the VNF is isolated from the underlying network function virtualization infrastructure (NFVI). For the management of VNF, the traditional maintenance management function of the VNF instance is performed by the EMS, and the life cycle management function of the VNF is completed by the VNFM. The underlying virtual infrastructure is managed by the Virtual Infrastructure Manager (VIM), while specific network traffic is typically done through one or more VNF instances. The management of network services is performed by the NFV orchestrator (NFVO).

In the embodiment of the present invention, the expansion and contraction of the VNF instance includes expansion and contraction, wherein the expansion includes two cases:

Scale out: When the VNF is composed of multiple Virtualisation Deployment Uni (VDUs), the VDU instances that make up the VNF instance are added to increase the capability of the VNF instance.

Scale up: increase the configuration of the virtual machine (VM) running the VNF instance, such as adding a central processing unit (CPU), memory, network port, etc., to increase the capability of the VNF instance;

Accordingly, the reduction also includes two cases:

Scale in: when the VNF is composed of multiple VDUs, reduce the VDU instances that make up the VNF instance to reduce the ability of the VNF instance;

Scale down: Reduces the configuration of VMs running VNF instances, such as reducing CPU, memory, network ports, etc., to reduce the ability of VNF instances.

In the various embodiments of the present invention, FIG. 2 is a schematic flowchart of Embodiment 1 of a virtualized network energy saving method according to the present invention. As shown in FIG. 2, the execution entity of this embodiment is an EMS, and the energy saving analysis and control functions are located. EMS, that is, EMS centralized energy saving, the method includes:

Step 101: Obtain energy saving information.

Here, the energy saving information includes: an energy saving cell and an energy saving trigger condition.

Specifically, in this step, the EMS obtains energy-saving information, where the energy-saving information includes: a cell that can save 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 the running data of the network in a certain period of time, and analyzes the collected running data to determine which cells can save energy and the energy-saving triggering conditions of the corresponding cell, where the energy-saving triggering conditions include However, it is not limited to: energy saving period, traffic threshold that triggers entry and exit of energy saving, and the like.

It should be noted that the energy saving period refers to a period in which energy saving can be performed, that is, a time T1 for starting energy saving and a time T2 for ending energy saving; the traffic threshold for triggering energy saving refers to a traffic threshold TL1 of a cell that can save energy and Industry for providing coverage for energy-saving communities The traffic threshold TL2, the traffic threshold for triggering the energy-saving to exit, refers to the traffic threshold TU1 of the cell used to provide coverage for the energy-saving cell. The traffic threshold TL1 indicates the number of access users of the energy-saving cell, and the value thereof may be set according to the performance of the system and the user's requirements, which is not limited herein; the traffic threshold TL2 represents the cell access user used to provide coverage for the energy-saving cell. Quantity, too, its value can be set according to the performance of the system and user needs, not limited here, TU1 is similar.

Step 102: When the energy-saving cell meets the energy-saving trigger condition, the energy-saving indication is sent to the base station corresponding to the energy-saving cell, and the energy-saving indication is used by the base station to control the energy-saving cell not to receive the service access.

In this step, when the energy-saving triggering condition of the energy-saving cell is satisfied, the EMS can perform the operation of entering the energy-saving operation, that is, the EMS sends a command to the base station corresponding to the cell that needs to save energy, so that the energy-saving cell no longer accepts new service access. . The energy-saving triggering condition that the energy-saving cell meets is that when the traffic volume of the energy-saving cell is less than the threshold TL1, and the traffic threshold of the cell used to provide coverage for the energy-saving cell is less than TL2, the energy-saving cell starts to enter the energy-saving state.

Step 103: When the VNF instance corresponding to the energy-saving cell does not support automatic scaling, the VNFM is controlled to reduce the VNF instance.

In this step, the EMS checks whether the VNF instance corresponding to the energy-saving cell supports automatic scaling. When it is determined that the VNF instance corresponding to the energy-saving cell does not support automatic scaling, the EMS sends a command to the VNFM, so that the VNFM performs the VNF instance corresponding to the cell that needs to save energy. The volume reduction can be divided into multiple progressive shrinkage to achieve energy saving in the virtualized network.

In the virtualized network energy-saving method of the embodiment, the EMS obtains the energy-saving information, and determines, according to the energy-saving information, that when the energy-saving cell meets the energy-saving trigger condition, the EMS sends an energy-saving indication to the base station corresponding to the energy-saving cell, so that the base station controls the energy-saving cell no longer. After receiving the new service access, and further determining that the VNF instance corresponding to the energy-saving cell does not support automatic scaling, the EMS sends a command to the VNFM to enable the VNFM to expand the VNF instance corresponding to the cell that needs to save energy, thereby implementing network energy saving. The method is applicable to the energy saving of the virtualized network, and overcomes the problem that the prior art is not fully applicable to the virtualized network.

In practical application, on the basis of the first embodiment, the method further includes: when the energy-saving exit condition is met, that is, when the traffic threshold of the cell used for providing coverage for the energy-saving cell is greater than TU1, the energy-saving cell exits the energy-saving state, and the EMS Perform an exit energy saving operation (not shown in Figure 2), including:

The EMS gives a command to the base station corresponding to the cell that needs to save energy, so that the cell starts accepting new Service access

The EMS checks whether the VNF instance corresponding to the energy-saving cell supports automatic scaling. If not, the EMS sends a VNF instance to the VNF instance to expand (progress). During the above-mentioned energy-saving process, the EMS needs to monitor the traffic volume of the cell that provides coverage for the energy-saving cell. If the traffic volume of the coverage cell exceeds the energy-saving threshold TU1, the EMS needs to perform the exit energy-saving operation in advance.

In practical application, based on the first embodiment, the method may further include:

If the energy-saving cell has no active service service, the base station corresponding to the energy-saving cell is controlled to close the radio frequency module corresponding to the energy-saving cell.

Specifically, when the cell that needs to save energy has no active service 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 service, Turn off the entire antenna.

Further, on the basis of the foregoing embodiment, the obtaining the energy saving information includes: collecting operation data of the network within a preset time period, and analyzing the operation data to obtain energy saving information; or receiving energy saving information sent by the NMS.

Specifically, there are two methods for the EMS to obtain energy-saving information. One is that the EMS collects the operational data of the network within a preset time period, analyzes the collected operational data, and obtains energy-saving information, thereby determining which cells can save energy and corresponding cells. The energy-saving triggering condition includes, but is not limited to, an energy-saving period, a traffic threshold that triggers entering and exiting the energy-saving, and the like; wherein, the preset time period may be a period of time before the current time, for example, starting from the current time. Calculate, calculate the period of 5 days forward, set the preset time according to network performance and user requirements, which is not limited here; the other is the step of the EMS not performing the above collection and analysis, and the step of performing the above collection and analysis by the NMS The energy saving information is obtained, and the NMS sends the energy saving information to the EMS, and the EMS receives the energy saving information delivered by the NMS, thereby obtaining the energy saving information.

Here, the energy saving information includes: an energy saving cell and an energy saving trigger condition;

Specifically, in this step, the NMS obtains energy-saving information, where the energy-saving information includes: a cell that can save energy and an energy-saving trigger condition of the energy-saving cell. The method for obtaining the energy-saving information by the NMS may be: the NMS collects the running data of the network in a certain period of time, and analyzes the collected running data to determine which cells can save energy and the energy-saving triggering conditions of the corresponding cell, where the energy-saving triggering conditions include However, it is not limited to: energy saving period, traffic threshold that triggers entry and exit of energy saving, and the like.

Access. The energy-saving triggering condition that the energy-saving cell meets is that when the traffic volume of the energy-saving cell is less than the threshold TL1, and the traffic threshold of the cell used to provide coverage for the energy-saving cell is less than TL2, the energy-saving cell starts to enter the energy-saving state.

Step 203: When the VNF instance corresponding to the energy-saving cell does not support automatic scaling, the VNFM is used to reduce the VNF instance by using the EMS.
