To create a connection between different mobile radio systems, data transmission between a first mobile services switching center (2GMSC) of a first mobile radio system (2G) and a second mobile services switching center (3GMSC) of a second mobile radio system (3G) is proposed, whereby the mobile services switching centers are connected through an interface (A*), via which useful data is transmitted at a variable useful data transmission rate, in which the useful data is transmitted within data frameworks including a definite pre-determined number of data fields, whereby, depending on the amount of useful data to be transmitted, at least one part of the data fields is first specified with the useful data and then the remaining part of the data fields is specified with dummy bits. Thus, a transmission channel which uses a fixed gross transmission rate (e.g., 64 kbit/s), but a variable useful data transmission rate (0-57.6 kbit/sec) is created.
