Abstract

An automated interactive customer class identification and contacting system for use in or for a cellular mobile radiotelephone (CMR) system. A mobile radiotelephone provides identification information as it originates a call or registers into the CMR system by powering up or initially entering the area of coverage of a cell. This identification information is monitored by a detection module, and predetermined identifying characteristics derived from the identification information identify the registering mobile radiotelephone as a member of a predetermined class, such as roamers. An interactive module places a telephone call to the registering mobile radiotelephone and provides synthesized voice message information targeted to the specific class of radiotelephones, for example, roamers. The interactive module is further responsive to DTMF inputs from the user of the telephone, for example to select services offered by the cellular system operator, block further solicitations, provide information requested by the cellular system operator, and the like. A database module stores information associated with the mobile telephone such as acceptance or rejection of services, last time of detection or solicitation, and the like.
