Abstract

Disclosed is a method for distributing, installing and operating software-defined radio-based radio application independent of hardware and a user application. The radio application comprises a radio controller code and a user-defined function block code. A radio application package for distributing and installing the radio application includes pipeline component metadata for constituting a pipeline of the radio application. The user-defined function block code may be provided in the form of an execution code, a source code or an intermediate representation, and the radio controller code and the user-defined function block code may call a standard function block. Accordingly, with the configuration of the radio application of the present invention and the method for distributing, installing and operating the radio application according to the present invention, various wireless communication systems can be used independently of a modem chip just by downloading and installing the radio application.

Claims

1. A radio application distribution method using a radio application package for installing a radio application into a terminal, the method comprising:

generating a radio application package; and

uploading the radio application package to a server,

wherein the radio application package includes radio controller codes, function block codes, and pipeline configuration metadata.

2. The method of claim 1, wherein the function block codes include:

standard function block codes which are codes calling function blocks implemented using dedicated hardware logics included in a radio processor of the terminal or codes operating on a core of the radio processor of the terminal; and

user-defined function block codes which are not provided as the standard function block codes or which are customized from functions provided by the standard function block codes.

3. The method of claim 2, wherein, when the standard function block codes are provided as execution codes executable on the radio processor of the terminal, the radio application package further includes a radio library comprising the execution codes.

4. The method of claim 2, wherein the user-defined function block codes are at least one of execution codes executable on the radio processor of the terminal, source codes which can be compiled into execution codes executable on the radio processor of the terminal, and intermediate representation (IR) codes which can be compiled into execution codes executable on the radio processor of the terminal.

5. The method of claim 4, wherein, when the user-defined function block codes are source codes or IR codes, the user-defined function block codes are included in the radio application package as encrypted.

6. The method of claim 2, wherein the pipeline configuration metadata define relations among the radio controller codes, the user-defined function blocks, and the standard function blocks for data transmission functions or data reception functions of the radio application.

7. The method of claim 1, wherein the radio controller codes are execution codes executed on an application processor or the radio processor of the terminal, provide a user application with context information of the radio application, and transmit/receive data with a networking stack of a communication service layer existing on the application processor or the radio processor.

8. A method for installing a radio application into a user terminal by using a radio application package, the method comprising:

downloading a radio application package from a server; and

installing a radio application included in the radio application package into the user terminal,

wherein the radio application package includes radio controller codes, function block codes, and pipeline configuration metadata.

9. The method of claim 8, wherein the function block codes include:

standard function block codes which are codes calling function blocks implemented using dedicated hardware logics included in a radio processor of the terminal or codes operating on a core of the radio processor of the terminal; and

user-defined function block codes which are not provided as the standard function block codes or which are customized from functions provided by the standard function block codes.

10. The method of claim 9, wherein, when the standard function block codes are provided as execution codes executable on the radio processor of the terminal, the radio application package further includes a radio library comprising the execution codes.

11. The method of claim 9, wherein the user-defined function block codes are at least one of execution codes executable on the radio processor of the terminal, source codes which can be compiled into execution codes executable on the radio processor of the terminal, and intermediate representation (IR) codes which can be compiled into execution codes executable on the radio processor of the terminal.

12. The method of claim 11, wherein, when the user-defined function block codes are source codes or IR codes, the user-defined function block codes are compiled using a compiler executed by the application processor or the radio processor of the terminal.

13. The method of claim 11, wherein, when the user-defined function block codes are source codes or IR codes, the user-defined function block codes are included in the radio application package as encrypted.

14. The method of claim 8, wherein the radio controller codes are execution codes executed on an application processor or the radio processor of the terminal, provide a user application with context information of the radio application, and transmit/receive data with a networking stack of a communication service layer existing on the application processor or the radio processor.

15. The method of claim 8, wherein, in the installing the radio application, the radio controller codes and the function block codes are installed into a storage device which can be accessed by at least one of an application processor and a radio processor of the terminal by referring to the pipeline configuration metadata.

16. A method of executing a radio application comprising function block codes and radio controller codes in a terminal having an application processor and a radio processor, the method comprising:
