Base station in a cellular radio system and a cellular radio system
First Claim
1. A base station for a cellular radio system which has a plurality of switching centres and plurality of base stations connected thereto by respective base station controllers through time-division respective telecommunication links, and an operations and maintenance centre, the base station comprising:
- a plurality of transceiver units,a time-division bus providing respective time slots for the base station,a multiplexer/demultiplexer means for multiplexing said telecommunication links and for demultiplexing data to be sent from said time-division bus of said base station to said telecommunication links,at least one switching means for selectively switching respective of the transceiver units to respective of the telecommunication links,the switching means being a time slot switch comprising;
a time slot counter for synchronizing the time slot switch with the time slots of the time-division bus,a time slot selection register responsive to operations and maintenance information including time slot selection data for time slot-specific storing and reading of said time slot selection data,a comparing means for comparing the time slot selection data contained in the time slot selection register with the state of the time slot counter at a given point of time in such a manner that the time slot selection data is compared with the state of the time slot counter and, responsive to the result of this comparison, the date contained in a respective time slot on a respective of said telecommunication links or at a respective one of the transceiver units is transmitted forward,a buffer means responsive to the data supplied by the comparing means for storing data contained on the respective one of said telecommunication links and for feeding the data into a respective one of the transceiver units, and for feeding data contained at a respective one of said transceiver units into the desired time slot on the respective one of said telecommunication links.

Abstract
A base station for a cellular radio system including switching centers and base stations connected thereto by time-division telecommunication links. The base station includes one or more transceiver units for establishing radio links, a multiplexer/demultiplexer for multiplexing transmission channels on the telecommunication links, for extracting synchronization and clock signals, and for demultiplexing data to be sent from the base station to a transmission channel of the telecommunication link. The base station further includes switches for switching respective transceiver units to respective transmission channels of the respective telecommunication links.
