Mobile telecommunication device and method used for changing wireless communication between base stations of different kinds

摘要

A remote unit has the ability to switch automatically from a public network to a non-public network comprising of private and residential base stations. In the preferred embodiment, the public network is characterized by cells with each cell having a unique identification signal. Initially, a first switchover from a public network to a non-public network requires the user to manually cause the switchover. The remote unit stores the first identification signal transmitted by the base station from which the remote unit traversed into the region covered by the non-public base station. In addition, the remote unit stores the identification signal associated with a cell of the public network previous to the current cell if the switchover occurred less than two (2) minutes from the exit of the previous cell. In this manner, the remote unit can adaptively learn as it traverses other possible paths from other cells into the region covered by the non-public base station.
