Abstract

A program updating apparatus for a radio base station includes a plurality of non-management radio base stations and a management radio base station. Each of the plurality of non-management radio base stations has a first program. The management radio base station stores a second program to which the first program is updated. The management radio base station transmits the second program to at least one of the plurality of non-management radio base stations such that the first program is updated to the second program. The non-management radio base station having the second program, as a first master radio base station, transmits the second program to another of the plurality of non-management radio base stations, as a first slave radio base station, which does not have the second program such that the first program is updated to the second program.

Description

technical field [0001] The present invention relates to a program updating device and method for a radio base station which can update the program of a radio base station in a dedicated radio telephone using a dedicated branch switching unit. Background technique [0002] As a PHS (Personal Handyphone System) service, new services such as character communication are being developed one after another. Usually, adding a new service requires changing the procedure of the wireless base station (CS). More specifically, due to consideration of the characteristics of radio wave transmission, wireless base stations are usually installed in places that are difficult to reach by hand, such as roofs. For this reason, once it is installed, it is difficult to perform program changing work such as changing ROM (Read Only Memory) and the like. Therefore, in order to update the program of the wireless base station, several program downloading methods have been proposed. [0003] A conven...
