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