Patent ID: 6950675

Claim:
A radio communications system comprising: at least one base station; and at least one wireless subscriber terminal which contains a transceiver in order to transmit and receive radio signals by at least two different radio transmission modes, and which contains a selector to select one of the at least two radio transmission modes at least prior to a subscriber connection being established with one of the at least one base stations, wherein the at least one base station also contains a transceiver in order to transmit and receive by various radio transmission modes, wherein the at least one base station is connected to a control means which determines an availability value for each of the various radio transmission modes with the aid of preselected criteria, and controls the base station in order to transmit to the at least one wireless subscriber terminal, an identification code for at least the radio transmission mode which has the highest availability value, wherein the control means creates a priority list for the at least one base station in which the identification codes for the radio transmission modes are listed in an order of precedence dependent on the size of respective availability values, wherein the base station transmits the priority list to the wireless subscriber terminal, wherein the wireless subscriber terminal receives the priority list and checks by means of the identification codes of the listed radio transmission modes whether at least one of the identification codes gives a radio transmission mode by which the transceiver of the subscriber terminal can transmit and receive radio signals, wherein the wireless subscriber terminal transmits to the base station, the identification codes for all the radio transmission modes by which the transceiver of the subscriber terminal can transmit and receive radio signals, and wherein the control means for the base station then creates the priority list by means of the identification codes transmitted by the subscriber terminal, the identification codes being listed in the priority list in an order of precedence dependent on the size of respective availability values.
