US 6,604,194 B1 · Program updating method and apparatus for communication terminal system

Abstract

A program updating method and apparatus update a system initialization code as well as a master code to a new version from a remote site. The program updating method according to the present invention includes a first step of determining whether or not the system initialization code source is executed, a second step of executing the system initialization code copy if the system initialization code source is not executed, a third step of determining whether or not a master code requires updating and thereby updating the same with a master code or a server according to the result of the above determination after the system initialization code source is executed, a fourth step of determining whether or not the system initialization code requires updating after updating the master code, and a fifth step of sequentially updating the system initialization code source/copy with a system initialization code of a server if it is determined that the system initialization code requires updating.

Dependent claims

In a communication terminal system which includes a network interface and updated data of a memory from a remote server, a program updating apparatus for a communication terminal system, comprising:

a memory having a master code and a system initialization code stored therein;
and
an initialization code control unit for controlling selection of an address of the memory so that a system initialization code copy may be executed after resetting the communication terminal system if a system initialization code source stored in the memory executes improperly,
wherein the initialization code control unit comprises:
first means for determining whether or not the system initialization code source is normal;
second means for resetting the system if the first means determines that the system initialization code source is not normal;
and
third means for providing address information of the system initialization code copy stored in the memory, automatically, if the second means resets the system.

In a program updating method for updating data from a remote server using a network, a program updating method for a communication terminal system, the method comprising:

a first step of determining whether or not a system initialization code source of a memory is executed;
a second step of executing a system initialization code copy of the memory according to the result of the first step;
a third step of determining whether a master code source or a master code copy of the memory requires updating or not after executing the system initialization code source or the system initialization code copy, and then, updating the master code source or copy with a master code of a server according to the result of this determination;
a fourth step of determining whether the system initialization code source or the system initialization code copy requires updating or not when the update of the master code source or the master code copy of the memory is completed;
and
a fifth step of sequentially updating the system initialization code source or the system initialization code copy of the memory with a system initialization code of a remote server when it is determined that the system initialization code source or the system initialization code copy requires updating.
