  • Patent number: 5103445
    Abstract: A method in a mobile radio communication system for adapting the system and communication to prevailing traffic and performance requirement. According to the invention a mobile station inserts information on particular codes in its messages transmitted to a base station in response to an invitation message from the base station. The codes indicate whether a message is new or retransmitted and/or message age. The base station receives radio signals in time slots identified in its invitation message and estimates for each time slot based on radio signals received in the time slot whether the time slot is empty or busy, or whether the time slot is empty or correct. For each message received and understood the base station retrieves the code. The retrieved codes and the number of empty/busy/correct slots enable the base station to estimate prevailing system traffic and performance.
