Abstract:
A method for implementing transmission in a mobile network includingbase stations (BTS) which form radio cells, mobile stations (MS) located in the area of the radio cells and connected to the base stations through radio channels, and at least one base station controller (BSC) connected to the base stations via a transmission network, the method comprising the steps of carrying out transmission in the transmission network in time slots of successive frames, implementing transmission from a mobile station via a radio channel to a base station and from the base station via a transmission channel to the base station controller, said transmission channel being made up by time slots of successive frames or parts thereof, establishing a common transmission link (TL) between several base stations and their common base station controller, allocating channels from the frame of the common transmission link (TL) for the use of the radio channels dynamically in such a way that any one of several different radio channels can use a specific channel on the transmission link, characterized by locating a combining network element (41, 42) at least at one point of said transmission link, in said network element, merging signals arriving from different base stations on a time slot basis by (1) using the contents of time slots arriving substantially simultaneously as input information for a logic operation, and by (2) performing said logic operation so that the result of the operation corresponds to the content of the time slot of the signal of the base station to which the time slot in question is allocated, said result forming at each time the content of a time slot of the frame used on the transmission link.
