摘要： A method and apparatus are provided for radio access technology (RAT) monitoring, in a wireless system environment having wireless communications equipment and at least two different RATs that coexist for providing to the equipment access to one or more communications networks. The equipment has at least two subsystems, each adapted for establishing and maintaining an active communications connection with a certain one of the different RATs. The equipment selects at least a first RAT, among all the RATs available in a certain geographical area, for establishing the active communications connection, according to a monitored characteristic of the first RAT. The method includes scanning a characteristic of a second RAT available for communication in the geographical area while the equipment maintains an active communications connection with the first RAT, and performing the scanning step when the equipment does not transmit signals through the active communications connection maintained with the first RAT.

摘要： A method is provided for channel scanning in a wireless communications system, for the identification of one or more narrow-band channels present in a certain frequency band and which can be used for connection between a wireless communications device and a communications network. The method includes: applying a FFT function to at least one signal corresponding to a given frequency band, providing for a set of coefficients each being representative of a frequency, analyzing the coefficients so as to detect at least one frequency region having at least one predetermined feature, and determining at least one channel position, by considering that each of the at least one frequency region having at least one predetermined feature is a guard band of one of the at least one channel.
