The invention is related to a base station for a cellular network, the base station being connected via the radio path to the mobile stations (MS) in the area of a cell formed by the base station and via a transmission network to the means controlling the base station (MSC). The base station comprises (a) a first group of units forming a physical interface for the transmission network and a radio interface for the mobile stations (MS), and (b) an internal bus system, which comprises several buses into which the units are connected and by means of which the units are connected to each other. In order to efficiently provide other telecommunications services, the base station has a second group of units, which forms at least one interface for other external devices, and the base station is equipped with an internal cross-connection for switching traffic at least between the external devices and the transmission network.

Base station for extended services

The invention relates to a method for implementing transmission in a mobile network in which base stations (BTS) communicate through a transmission network with a base station controller (BSC) and through a radio path with mobile stations (MS). In order that the transmission of the fixed part of the mobile network may be implemented in a simpler way than heretofore, a common transmission link (TL) is established between several base stations and their common base station controller, a combining network element ( ) being located at least at one point of the transmission link in which network element signals arriving from different base stations are combined of the base station to which the time slot basis for incorporation into the time slots of the frame structure used on the transmission link in such a way that the signal 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.
