Radio base station program update method and apparatus not requiring update host computer

A program updating method of a radio base station, comprising:

• (a) providing a plurality of non-management radio base stations, wherein each of said plurality of non-management radio base stations has a first program and each said non-management radio base station includes a program transfer unit and a program receiving unit,
• (b) providing a management radio base station storing, in a Read Only Memory (ROM), a second program to which said first program is updated, said management radio base station having a program transfer unit;
• (c) setting any one of said plurality of non-management radio base stations as an N-th (N is an integer equal to or more than 1) slave radio base station;
• (d) transmitting said second program to said N-th slave radio base station from said program transfer unit in said management radio base station to a program receiving unit of said N-th slave radio base station to update said first program of said N-th slave radio base station to said second program;
• (e) setting said N-th slave radio base station having said second program as an M-th (M is an integer equal to or more than 1) master radio base station;
• (f) setting any one of said plurality of non-management radio base stations which does not have said second program, as an (N+1)-th slave radio base station;
• and
• (g) transmitting said second program to said (N+1)-th slave radio base station from said M-th master radio base station to update said first program of said (N+1)-th slave radio base station to said second program, said transmission using said program transfer unit in said M-th master radio base station to transmit to said program receiving unit in said (N+1)-th slave radio base station.

A program updating method of a radio base station, comprising:

• providing a plurality of radio base stations, wherein each of said plurality of radio base stations has a first program stored in a Read Only Memory (ROM);
• providing a second program to which said first program is to be updated, said second program stored in a ROM;
• installing said ROM containing said second program into one of said plurality of radio base stations;
• and
• transmitting said second program to one of said plurality of radio base stations which does not have said second program, wherein said first program stored in said ROM of the receiving radio base station is rewritten to be said second program.

A computer readable recording medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to perform a radio base station program updating method, said method comprising,

• (a) recognizing, in any of a plurality of non-management radio base stations, a status of non-management radio base station, wherein each of said plurality of non-management radio base stations has a first program stored in a Read Only Memory (ROM);
• (b) recognizing, in a management radio base station storing a second program to which said first program is updated, a status of management radio base station;
• (c) setting any one of said plurality of non-management radio base stations as an N-th (N is an integer equal to or more than 1) slave radio base station;
• (d) transmitting said second program to said N-th slave radio base station from said management radio base station to update said first program of said N-th slave radio base station to said second program;
• (e) setting said N-th slave radio base station having said second program as an M-th (M is an integer equal to or more than 1) master radio base station;
• (f) setting any one of said plurality of non-management radio base stations which does not have said second program, as an (N+1)-th slave radio base station;
• and
• (g) transmitting said second program to said (N+1)-th slave radio base station from said M-th master radio base station to update said first program of said (N+1)-th slave radio base station to said second program.
