Description

Waveform loading method, device and equipment and readable storage medium

Technical Field

The present invention relates to the field of software wireless technologies, and in particular, to a waveform loading method, apparatus, device, and computer-readable storage medium.

Background

With the development of software wireless technology, the realization of various software platform architectures has come up. Therefore, a design specification for a universal Communication system, namely a Software Communication Architecture (SCA), is provided, and the application of the design specification can enable the functions of the system to be not focused on the realization of specific hardware functions, but mainly on the development of the application, thereby obviously improving the flexibility, the universality, the reconfigurability and the interoperability of the Communication system.

The core idea of the SCA is to implement different functions by deploying different waveform components to a general hardware platform, specifically, copying a waveform component related file to a directory specified by a corresponding processor for the processor to start the waveform components, so that the update of a radio station can be implemented only by replacing the waveform components therein, thereby completing the waveform loading.

The existing waveform loading mode directly copies the related files of the waveform components to the appointed directory of the corresponding processor, does not consider the loading delay caused by the fact that the same waveform is deployed for multiple times and copied for multiple times, and reduces the working efficiency of a software radio system. Especially, under the condition that the related files of a multi-platform software radio system or a waveform component are large, the waveform deployment efficiency can be seriously influenced by copying, and further, the communication timeliness of the software radio system is influenced.

In summary, how to effectively solve the problem of time-dependent degradation of software radio system communication caused by multiple times of deployment and multiple copies in the existing waveform loading manner is a problem that needs to be solved urgently by those skilled in the art at present.

In most cases, a deployed waveform component exists in a processor, and attribute information corresponding to the deployed waveform component is stored in advance. When the processor needs to perform waveform loading, whether deployed waveform components are pre-stored or not can be judged in advance, and if the deployed waveform components are pre-stored, stored attribute information corresponding to stored components in a stored component set formed by deployed waveforms is acquired after target attribute information of the target waveform components is acquired for each target waveform component.

S106: and determining the deployed waveform component corresponding to the stored attribute information consistent with the target attribute information as the target waveform component.

When the target attribute information exists in the stored attribute information, the processor is explained to be pre-deployed with the target waveform component, and the deployed waveform component corresponding to the stored attribute information consistent with the target attribute information is determined as the target waveform component.

S107: and starting each target waveform component to finish the waveform loading operation.

After the target waveform components are determined, the target waveform components are started, so that the waveform loading operation can be completed by directly starting the deployed waveform components, the waveform loading process is optimized, the waveform loading time is saved, the software radio waveform starting time is shortened, the software radio waveform timeliness is improved, and the working efficiency of the whole software radio system is improved.

S206: and judging whether the target program file exists in each stored program file, if not, executing step S207, and if so, executing step S208.

After the stored program files contained in the stored attribute information are obtained, whether an object program file exists in each stored program file is judged, if not, it is indicated that the waveform component to be loaded does not exist in the processor currently, step S207 is executed, if so, it is indicated that the waveform component to be loaded may exist in the processor currently, and step S208 is executed.
