摘要

The present invention relates to a method and system for updating software in a network element of a telecommunication network the units of which are divided into an original side and testing side, and which system comprises a network element (110), comprising units (111) that are logically divided into an original side and testing side, an original software (110<1>) for performing traffic transmitting tasks, and a new piece of software to be tested and/or introduced (110<2>). According to the invention, the system comprises one or more test connections (112) directed into the units of testing side (111R1...RN) loaded with the new piece of software (110<2>), in order to be able to test the new piece of software in question. The invention provides the advantage that it makes it possible to carry out test connections when testing a new piece of software in a network element of a telephone network. Moreover, owing to the invention, a new piece of software may be introduced in a network element of a telephone network maintaining the existing connections at the same.
