Method of transmitting data information in a mobile, cellular radio communication system

Claim 1

Method of transmitting in a cellular mobile radio system a radio communication message which is communicated according to the time division multiple access (TDMA) principle with a predetermined bit frequency in frames, each containing a number of time slots carrying radio communication message, the system communicating said messages in cells each served by a base station and having various degrees of utilization for a given cell, the number of time slots in each frame being greater than the greatest number of radio communication messages in progress between the mobiles in a cell and said base station serving that cell, said method including: extending the radio communication message from a certain mobile to said base station beyond the ordinary time slot allocated to said mobile in a frame by allocating further time slots within said frame for said mobile, at least one of said further time slots being occupied by said radio communication message in dependence on the distance of the mobile to the base station, and reducing said predetermined bit frequency from its ordinary value to a new value dependent on the total number m of allocated time slots in a frame.
