DEVICE AND CONTROL PROCEDURE FOR FDD AND NON-FDD BANDWIDTH

摘要

A device (d) is dedicated to the control of the frequency bands used by a user's terminal (3 - 1) adapted to be connected to a radio access network (4) with a duplexing in frequency, of a mobile communication network having first and second sets of blocks of the frequencies allocated to the communications by duplexing in frequency, said blocks of frequencies of a first type, respectively dedicated to uplink and downlink, and at least a third set of blocks of frequencies of a second type which is separate from the first type, this network providing at least one service without a return path. This device (d) comprises i) of the analysis means (mc), adapted to be activated in the case of setting up by the user's terminal (3 - 1) of a communication resting on an uplink on a given frequency of the first assembly and to a downlink on a given frequency of the second assembly, and able to analyze signalling information received by the user's terminal (3 - 1) on the down link is established, and ii) of the tilting means (mc), adapted to be activated in the event of detection by the analysis means of a signalling information indicating the provision of a service on a given frequency of a second type, and able to tilt the downlink on the block of a given frequency of the second type.
