Method and device for handling telephone calls directed to non-reachable mobile phones

A method for handling telephone calls to a non-reachable radio mobile phone, and for handling data pertaining to them, like the telephone number of the calling subscriber, the time of the telephone call, and any additional information relating to the calling subscriber, characterized in that it is started by an event like a voice call, which in turn originates a notification through a recordable SMS text channel, the method comprising the two following distinct steps of:

• I—routing the telephone call to a device for storage and management of data relating to the phone call, when the called subscriber is not reachable, due to the subscriber mobile phone being in the detach mode or due to the absence of a radio-frequency signal, and when, at the same time, the call diversion service towards the answering service or another phone number is not operative;
• II—transmitting, that is noticing, to the called subscriber, at the moment the mobile phone is reachable again, all SMS texts including data relating to the calls missed in the period when the subscriber was not reachable;
• the method being based on a protocol, in which the usual steps sequence for performing a mobile telephone line call, is first started and thereafter immediately interrupted after the signaling and acquisition of the subscriber identification, and this steps sequence is resumed at the time it has been ascertained that the radio mobile phone is reachable again, but actuating this time an SMS text channel, so as to completely eliminate the actual serial operative step sequence (transaction), typical of a voice communication protocol, thereby producing, in fact, a traffic having a virtual nature:
