Method and device for exchanging messages between systems based on different protocol versions.

摘要

The methods and device according to the invention supplement messages which are to be exchanged between systems based on different protocol versions and are provided with an information element of a second type with an information element of a first type, and vice versa, as a result of which greater design freedom in the development of subsequent compatible protocol versions as well as subsequent non-compatible protocol versions is obtained and systems based on non-compatible protocol versions can even communicate directly with any type of receiving system. Furthermore, in this arrangement the drawback of it being necessary to know in advance on what protocol version the receiving system is based, does not apply.
