A method for establishing telecommunications links in a switching system includes the steps of providing terminal devices and a base station having transmitting/receiving devices. The number of terminal devices is greater than the number of transmitting/receiving devices. A transmission of useful information and/or signaling information is performed between a transmitting/receiving device and a given terminal device in a first transmission cycle. The transmission between the transmitting/receiving device and the given terminal device is subsequently interrupted for a given time period. The given time period lasts as long as a transmission period of at least one transmission frequency. The transmission between the transmitting/receiving device and the given terminal device is continued in a second transmission cycle in time after the given time period has elapsed. A switching system is also provided.

DETAILED DESCRIPTION It is accordingly an object of the invention to provide a method for establishing telecommunications links and a corresponding switching system which overcome the above-mentioned disadvantages of the heretofore-known methods and systems of this general type and which provide improved transmission capabilities.
With the foregoing and other objects in view there is provided, in accordance with the invention, a method for establishing telecommunications links in a switching system, in particular in a mobile communications system.
The method comprises the steps of providing a first number of terminal devices; providing a base station having a second number of transmitting/receiving devices assigned to the terminal devices, the first number being greater than the second number; transmitting a useful information and/or a signaling information at different times and using a redundant coding, from a transmitting/receiving device of the second number of transmitting/receiving devices to a given terminal device of the first number of terminal devices in a first transmission cycle in time with at least one transmission frequency of a plurality of transmission frequencies specific to the transmitting/receiving devices; subsequently interrupting a transmission from the transmitting/receiving device to the given terminal device for a time period equivalent to a transmission period of at least one of the plurality of transmission frequencies; and continuing the transmission from the transmitting/receiving device to the given terminal device in a second transmission cycle in time after the time period has elapsed.
In accordance with another mode of the invention, at least one of the useful information and the signaling information is transmitted from the transmitting/receiving devices of the base station to the terminal devices with only a part of the plurality of transmission frequencies being specific to the transmitting/receiving devices and being available to the terminal devices
