Call logging in cellular subscriber stations.

摘要

A system for collecting within a mobile subscriber station (102) of a cellular radio system the key elements of telephone billing information for subsequent retrieval. Information about the connected party's number (11), the time of the call (12) and the duration of the call (13) are collected in real time and stored in a non-volatile memory. Such information is selectively retrieved from the memory of the subscriber station on command (63) and a bill for use of the subscriber station calculated on the spot (by a mobile station rental agency, for example).
