Abstract:
A program updating apparatus for a radio base station, comprising:a plurality of non-management radio base stations, wherein each of said plurality of non-management radio base stations has a first program; a management radio base station storing a second program to which said first program is updated; and a switching unit to which each of said plurality of non-management radio base stations and said management radio base station are connected, wherein said management radio base station transmits said second program to at least one of said plurality of non-management radio base stations such that said first program is updated to said second program, said non-management radio base station having said second program, as a first master radio base station, transmits said second program to another of said plurality of non-management radio base stations, as a first slave radio base station which does not have said second program, such that said first program is updated to said second program, said switching unit has a management table and refers to said management table to connect each of said plurality of non-management radio base stations and said management radio base station, said management table has a first memory area in which an identification number data assigned to each of said plurality of non-management radio base stations is stored and a second memory area in which a data indicative of a state of each of said plurality of non-management radio base stations is stored, said state data indicating whether or not said non-management radio base station has said second program and whether or not said non-management radio base station is transmitting or receiving said second program, and said switching unit refers to said second memory area to retrieve said state data indicating that said non-management radio base station does not have said second program and said state data indicating that said non-management radio base station has said second program, and selects said master radio base station and said slave radio base station based on said retrieved result to connect aid selected said master radio base station to said selected slave radio base station.
