Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. However, it should be noted that the following embodiments are only examples for helping to understand the technical solutions, and are not intended to limit the present invention.

[0055] Such as Figure 1a As shown, the content of one embodiment of the present invention is as follows.

[0056] Optionally, this embodiment further includes the following content.

[0057] 1010. The first NF device sends a first call message to the NFV middleware device, where the first call message includes the identifier of the second NF that the first NF device requests to call and a public application program interface (application program interface in English) , the English abbreviation is API), indicating that the first NF device requests to call the second NF through the public API.

[0058] The NFV middleware is an intermediate component that realizes ...

Abstract

Disclosed in an embodiment of the present invention is a method of invoking a network function (NF), the method comprising: a network function virtualization (NFV) middleware device receives a first invoking message sent by a first network function (NF) device; the NFV middleware device determines an identifier of a first private API according to an identifier of a common API carried in the first invoking message, an identifier of a second NF carried in the first invoking message and a first correspondence stored in the NFV middleware device; the NFV middleware device invokes the second NF via the first private API corresponding to the identifier of the first private API. Thus, the first NF device can invoke the second NF via the common API when not being able to invoke the second NF directly.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for invoking network functions. Background technique [0002] In order to reduce the cost of network equipment and enable faster service deployment, the industry proposes the technology of network function virtualization (NFV for English abbreviation, full name for network function virtualization in English). NFV technology converts network functions implemented by proprietary hardware into one or more network functions implemented by software on standard or common IT equipment, such as servers, Ethernet switches or storage devices. Since the transformed network function is not realized by dedicated hardware, but by software on the IT device, this network function is called a virtual network function (abbreviated as VNF in English, full name in English as virtual network function ) to distinguish it from network functions implemented by proprietary hardware....
