Method of operating radio communications systems using SDR (software defined radio) radio stations

摘要

Authorization data is sent to radio stations so that the radio stations are temporarily authorized, by way of the authorization data, to communicate using radio access technology. Messages can be transmitted between a first radio station and a second radio station via a path that runs via one or more additional radio stations. The authorization data is sent such that, while a message is transmitted via the path using radio access technology, at any point in time a subset of adjacent radio stations on the path are authorized to communicate using radio access technology.

1. A method for operating a cellular radio communications system, comprising:
sending authorization data from a base station to mobile stations in the cellular radio communications system, whereby only a subset of the mobile stations are temporarily authorized, by way of the authorization data, to communicate using radio access technology to transmit messages between a first mobile station and a second mobile station via a path that runs via at least one additional mobile station, wherein the authorization data, which is shared among the first mobile station, the second mobile station, and the at least one additional mobile station on the path, is sent such that, while a message is transmitted via the path using the radio access technology, at any point in time only a given subset of the mobile stations on the path is authorized, by way of authorization data, to communicate using the radio access technology, wherein authorization is withdrawn from the first mobile station once the message is transmitted, and wherein any of the given subsets do not comprise all of the mobile stations on the path.
