Abstract
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.
