Method and apparatus for downloading an operating system or an application in cdma system
First Claim
1. An apparatus for downloading a unified operating system (OS) or application (AP) from a base station manager (BSM) and installing the same on a base station controller (BSC) in a CDMA communication system, the apparatus comprising:
- a BSM for uploading the unified OS or AP stored in an RAM disk of the BSM; and
a BSC processor for downloading the unified OS or AP from the BSM, selectively reading a corresponding part of the downloaded unified OS or AP by checking an Electrically Erasable and Programmable Read Only Memory (EEPROM) having board information pre-stored therein, and storing the selected OS and AP in an Embedded Programmable Logic Device (EPLD).

Abstract
The present invention is directed to a method and apparatus for downloading an operating system (OS) or an application and installing it on a set of base station controllers (BSCs) in a CDMA mobile communication system. According to the present invention, when a newer version of an OS or application needs to be installed on the set of BSCs, each of the BSCs is informed of the need for updating an OS or application by the base station manager (BSM), and simultaneously downloads the OS or application from the BSM for installation. This may diminish the traffic overload between the BSM and the BSCs by reducing the number of additional control signals communicated when the BSCs individually download the OS or application.

2. A method for downloading a unified operating system (OS) from a base station manager (BSM) and installing the same on a base station controller (BSC) in a CDMA communication system, the method comprising the steps of:
-
at the BSM, generating and transmitting a request signal to start downloading the unified OS to the BSC;
at the BSM, determining whether a response to the request is received from the BSC;
at the BSM, upon receipt of the response, uploading the unified OS, including a R1 type of OS and a R2 type of OS, stored in an RAM disk of the BSM to the BSC;
at the BSC, comparing a version of the downloaded unified OS with a version of an OS stored in an EEPROM of the BSC;
at the BSC, if the version of the downloaded unified OS is a newer one than the version of the BSC'"'"'s OS, determining whether a type of the BSC'"'"'s OS is R1 or R2; and
if the type of the BSC'"'"'s OS is R1, selectively reading an R1 part of the downloaded unified OS and installing the same on the BSC. - View Dependent Claims (3, 4, 5)

6. A method for downloading a unified application (AP) from a base station manager (BSM) and installing the same on a base station controller (BSC) in a CDMA communication system, the method comprising the steps of:
-
at the BSM, generating and transmitting a request signal to start downloading the unified AP to the BSC;
at the BSM, determining whether a response to the request is received from the BSC;
at the BSM, upon receipt of the response, uploading the unified AP, including a R1 type of AP and a R2 type of AP, stored in an RAM disk of the BSM to the BSC;
at the BSC, determining whether a type of the BSC'"'"'s AP is R1 or R2; and
at the BSC, if the type of the BSC'"'"'s AP is R1, selectively reading a R1 part of the downloaded unified AP and installing the same on the BSC. - View Dependent Claims (7, 8, 9)
