<p>A method and apparatus providing communications between mobile units (e.g. 100) and other communications devices (e.g. 20), is disclosed wherein, in response to a request to call a mobile unit (100) from an originating communications device (20), a paging signal is sent via a global communications network (60) and received by a mobile unit (100). The paging signal contains caller and callee identification codes, which are decoded by the mobile unit (100). A paging response signal, in the form of a reverse call setup signal, is then transmitted from the mobile unit (100) to the originating communications device (20). Transmission of the paging signal is preferrably stopped when a correspondence condition exists such that the caller and callee identification codes of the paging signal correspond to the caller and caller identification codes of the paging response signal. <IMAGE></p> |
