Replacing software at a telecommunications platform

摘要

Software in the form of a program (60) is replaced (e.g., upgraded) on a telecommunications platform (node) (620, 20) without shutting down the telecommunications functions of the platform. The old program (601.0) that is replaced is of a type which stores state information in a state storage system (200). In connection with a software (program) replacement operation for the old program, after a new program (601.1) is started either a shutdown (2-4) instruction is sent to the old program, a software support function of the platform activates a conversion program (80). The conversion program renders the state information of the old program as converted state information which is usable by the new program.
