Abstract:
A method (100) for 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), in which the mobile services switching centers (2GMSC, 3GMSC) are connected (110) via an interface (A*) through which useful data are transmitted at a variable useful data transmission rate, in which the useful data are transmitted (120) within data frameworks (F1, F2), which include a definite pre-determined number of data fields (1D1 . . . 1D36; 2D1 . . . 2D36; 8D1 . . . 8D36), whereby at first, depending on the amount of useful data to be transmitted, at least one part (1D1 . . . 4D19) of the data fields is first encoded with the useful data (122) and afterwards the remaining part (4D20 . . . 8D36) of the data fields is encoded with dummy bits (123).
