Abstract (en)

[origin: DE19734935A1] The invention relates to a method for packet oriented critical time-critical information transmission via a radio interface between a base station and mobile stations pertaining to a TDMA mobile communication system. During a logical link, a request for upward radiotechnic resources is sent by a mobile station with a service profile for time-critical information in part of a channel solely assigned to said profile in an upward direction without prior allocation of precise transmission time by the base station. The base station receives the request, evaluates it and carries out a modified allocation of radiotechnic resources for transmission of a useful signal in an upward direction to said mobile station. The invention can be used particularly advantageously in TDD mobile radio telephone services with TDMA/CDMA subscriber separation.
