Abstract

Disclosed is a method for distributing, installing, and operating a software-defined radio-based radio application independent of hardware and a user application. A radio application distribution method for installing a radio application in a user terminal using a radio application package comprises the steps of: generating a radio application package including a radio controller code, compiled by an application processor compiler, and a user-defined function block; and uploading the radio application package to a server, wherein the radio controller code is in the form of an execution code executed by an application processor or radio computer of the user terminal, and provides a user application of the user terminal with context information of a radio application to be installed in the user terminal or defines a radio controller for transmitting and receiving data with a networking stack of a communication service layer located in the application processor.

1. A radio application distribution method for installing a radio application in a user terminal using a radio application package (RAP), comprising:

generating a RAP including radio controller codes compiled by an application processor (AP) compiler and user-defined function block codes; and

uploading the RAP to a server,

wherein the radio controller codes are in form of executable codes executed by the AP or a radio computer of the user terminal, provide a user application of the user terminal with context information of a radio application to be installed in the user terminal, or define a radio controller for transmitting and receiving data with a networking stack of a communication service layer located in the AP,

wherein the user-defined function block codes are included in the RAP in form of executable codes executed on the AP or the radio computer, or in form of source codes or intermediate representation (IR) which can be compiled to codes executable on the AP or the radio computer, and

wherein the RAP further comprises pipeline configuration metadata for configuring pipelines of the radio application when the user-defined function block codes are included in the RAP in form of source codes or the IR, and the pipeline configuration metadata define relations among the radio controller codes, the user-defined function block codes, and the standard function block codes for data transmission functions or data reception functions of the radio application.

2. The radio application distribution method according to claim 1, wherein the RAP further comprises standard function block codes when the user-defined function block codes are included in the RAP in form of executable codes, and radio application codes including the standard function block codes and the user-defined function block codes are included in the RAP as compiled by at least one compiler.

3. The radio application distribution method according to claim 1, wherein the user-defined function block codes are included in the RAP as compiled by a front-end compiler when the user-defined function block codes are included in the RAP in form of source codes.

4. A radio application installation method for installing a radio application in a user terminal using a radio application package (RAP), comprising:

downloading, from a server, a RAP including radio controller codes compiled by an application processor (AP) compiler of a radio application supplier and user-defined function block codes; and

installing the RAP in the user terminal,

wherein the radio controller codes are in form of executable codes executed by the AP or a radio computer of the user terminal, provide a user application of the user terminal with context information of a radio application to be installed in the user terminal, or define a radio controller for transmitting and receiving data with a networking stack of a communication service layer located in the AP,

wherein the user-defined function block codes are included in the RAP in form of executable codes executed on the AP or the radio computer, or in form of source codes or intermediate representation (IR) which can be compiled to codes executable on the AP or the radio computer,

wherein, when the user-defined function block codes are included in the RAP in form of source codes, configuration codes including the user-defined function block codes are compiled to executable codes by a compiler of the user terminal or a compiler of a cloud connected to the user terminal with pipeline configuration metadata of the RAP, and the compiled executable codes are installed in a storage device of the user terminal by an installer of the user terminal together with the radio controller included in the RAP, and wherein, when the user-defined function block codes are included in the RAP in form of the IR, the configuration codes including the user-defined function block codes are compiled to executable codes by a back-end compiler of the user terminal or a back-end compiler of the cloud connected to the user terminal with the pipeline configuration metadata of the RAP, and the compiled executable codes are installed in a storage device of the user terminal by the installer of the user terminal together with the radio controller included in the RAP.

5. The radio application installation method according to claim 4, wherein the RAP further comprises standard function block codes when the user-defined function block codes are included in the RAP in form of executable codes, and configuration codes including the standard function block codes and the user-defined function block codes are installed in a storage device of the user terminal by an installer of the user terminal together with the radio controller or the radio controller codes included in the RAP.

6. The radio application installation method according to claim 4, wherein, when the user-defined function block codes of the configuration codes are compiled by referring to the pipeline configuration metadata, the compiler generates the executable codes by compiling the user-defined function block codes together with standard function block codes in a radio library of the user terminal.

7. The radio application installation method according to claim 4, further comprising, before the installing the RAP in the user terminal, decrypting the configuration codes by using a decryptor of the user terminal or a decryptor of a cloud connected to the user terminal, and providing the decrypted configuration codes to the compiler.

8. The radio application installation method according to claim 4, wherein, when the user-defined function block codes of the configuration codes are compiled by referring to the pipeline configuration metadata, the compiler generates the executable codes by compiling the user-defined function block codes together with standard function block codes in a radio library of the user terminal.
