Data transmission from a controller to successive bases stations linked in series
First Claim
1. A data transmission method in a cellular radio system comprising as network elements a base station controller and a plurality of base stations connected in series to said base station controller via a succession of data transmission links,said method comprising the steps of:
- (a) transmitting data in a direction over said links, in a succession of frames each divided into a regular succession of a given number of timeslots, so that, in reference to said direction one of said network elements is a first one of said network elements, and a next one of said network elements is a second one of said network elements;
(b) as one part of said transmitting, transmitting in said direction configuration data intended for said first one of said network elements in a predetermined timeslot of said frames;
(c) as another part of said transmitting, transmitting in said direction configuration data intended for said second one of said network elements to said first one of said network elements in another timeslot of said frames; and
(d) as yet another part of said transmitting, transmitting in said direction said configuration data intended for said second one of said network elements from said first to said second network element in said predetermined timeslot of said frames.

Abstract
A data transmission method in a cellular radio system, comprising as network elements a base station controller and base stations connected in series thereto via data transmission links. Data is transmitted over the data transmission links in frames divided in time slots. To control the data transmission network formed by the data transmission links, configuration data indicating in which time slots of the frames the useful data intended for the network elements is carried is transmitted to the network elements in a predetermined time slot of the frames.
