And before deleting the target virtual machine, waiting for the completion of the session, thereby ensuring the normal completion of the stock call and achieving the purpose of call loss prevention in the capacity reduction process.
As a first example, referring to fig. 4, fig. 4 shows a specific example of a capacity reduction process:
the capacity reduction process mainly comprises the following steps:
1, sending a capacity reduction instruction to an OMC of the AS by the VNFM, wherein the capacity reduction instruction carries identification information of a target virtual machine of a target VDU.
and 2, the OMC informs the LB of logging out the configuration parameters of the target virtual machine.
Specifically, the OMC receives a capacity reduction instruction, and acquires identification information of a target AS carried in the capacity reduction instruction.
And determining the signaling address and the port identification number of the outbound service registered by the target VDU according to the identification information, and canceling the signaling address and the port identification number of the outbound service from the service group of the AS through LB.
and after logout, a new call is not sent to the service address subsequently, and the new call is loaded and shared by the rest service addresses in the service group.

Referring to fig. 5, a capacity modification method based on network function virtualization NFV according to another embodiment of the present invention is described below by taking a capacity expansion process as an example.
Specifically, the method is applied to the AS, and comprises the following steps:

step 503, obtaining the configuration parameters of the target virtual machine, and determining that the parameter processing operation corresponding to the modification operation is a registration operation for the configuration parameters.
Step 504, the registration operation is executed on the configuration parameters of the target virtual machine.
In the above embodiment, when a capacity modification instruction indicating a capacity expansion operation is received, the configuration parameter of the target virtual machine is acquired, and a registration operation is performed on the configuration parameter, so that the AS provides a uniform service address to the outside according to the configuration parameter without a network element cooperating with a modification operation; the AS capacity expansion process can not modify the existing virtual machine, so that the inventory calling is not influenced; the automation degree of the AS capacity expansion process is higher, and manual intervention is not needed. And after the target virtual machine is normally started, the registration operation is executed again, and a new call session is received, so that the problem of call loss does not exist in the capacity expansion process.
And when the completion of the execution of the registration operation is detected, load balancing is carried out on the target virtual machine and the original virtual machine of the AS.
As a second example, referring to fig. 6, fig. 6 shows a specific example of the capacity expansion process:
The capacity expansion process mainly comprises the following steps:
1, sending a capacity expansion instruction to an OMC of the AS by the VNFM, wherein the capacity expansion instruction carries indication information of a newly added virtual machine of the target VDU, and the added AS is the target AS.
And 2, the OMC acquires a preset configuration file of the current bearer service.
and 3, applying the preset configuration file to a target virtual machine by the OMC and starting the target virtual machine.
And 4, the OMC acquires the configuration parameters of the target virtual machine, registers the configuration parameters of the target virtual machine on a load balancer, and performs load balancing after the registration is completed, so that the target virtual machine and the original target virtual machine share the service.
in the above example of the present invention, the LB provides a unified address to the outside, and the outside cannot sense the expansion process inside the AS, and does not need to modify the external network element; an OMC component is introduced, and modification operation of an existing virtual machine is not involved in the capacity expansion process of the AS, so that the inventory calling is not influenced; the automation degree of the AS capacity expansion process is higher, and manual intervention is not needed. After the target virtual machine is normally started, the virtual machine is registered on the LB, and a new call session is received, so that the problem of call loss does not exist in the capacity expansion process.
