Method for dynamic time slot allocation of the organisation channel of cellular mobile radio networks depending on traffic volume

Abstract: Mobile radio networks with cellular radio area division use an organisation channel, which is assigned to the radio cells by temporally offset time slots in time division multiple access, for connection set-up, connection monitoring and signalling procedures for the mobile radio subscribers. The time slots are intended to be allocated to the radio cells in optimum fashion for the radio cells, taking into account the traffic volume which varies through time. This is achieved with the aid of a subscriber management computer system, present in any case, which can also convert instantaneously unused speech channels as required into auxiliary organisation channels whose time slots are then available in addition.
