GSM INCOMING CALL AUTO-BLOCKING

Utilization of Rich GSM Call Control Information during Call Setup to Auto-Block Certain Unwanted Incoming Calls as a Value-Added Supplementary Service

Disclosed Anonymously

Explore the GSM phone call setup procedure, extract the incoming call number information from L3 call control message9s) to do an auto call screening on mobile devices based on user's setting,  simulating end user's operation to reject the unwanted phone calls automatically without disturbing/ringing the user, to providing some extra convenient supplementary phone barring service.

Our current GSM mobiles don't have a smart incoming (phone) call blocking/screening feature (unlike outgoing phone calls). Sometimes mobile users don’t want to be disturbed by certain number of phone unwelcome calls (e.g., harassing calls) or  at certain time (e.g. sleeping, dating time, etc), and still want to keep the device alive for any other good phone calls. We have not provided such convenience.

A few examples to show the existing problems:

(1) A young lady still receive her ex-boyfriend’s disturbing call (e.g., 416-123-4567) time to time, even at midnight, while she has a new & better one already.

(2) A husband doesn’t want to be traced by her wife (416-222-2222) for some special activities during certain time (e.g. in extremely important meetings or dating).

(3) Some wealthy man or pretty lady receives harassment calls (416-444-4444) again and again during happy family time or sleeping time.

What will these mobile users with special requirement or in special situation do? Here are some alternatives:

   A. They manually reject the call by clicking “end,” “ignore,” etc., again and again. This wastes time and is troublesome and disturbing.

   B. They turn off the mobile to deny all phone calls from all other people just because they are mad and do not want an unwelcome call. However, this may be a risky choice because one might miss important calls.

    C. One may also change a SIM card with a new phone number and tell this to good friends, co-workers etc.  However, this may be expensive, time-consuming, and inconvenient for friends.

The proposed solution is as follows:

1. In mobile application (user interface level), update the software to enable users to set up a personal automatic incoming-call blocking list (normally from "Setting > Option > IncomingCallRejecter" item or "Phone>Options" menu):

           416-123-4567 (unwanted ex-boy friend)

           416-222-2222 (no call from wife this moment)

           416-444-4444 (unwanted harassing calls at midnight)

Named as "auto-incoming-call rejecter list". This list can be edited in advance by users before the bad calls come in, and can also be expanded dynamically to include a phone number from a call-log-notification message when this user doesn't want to receive that call any more  (just like to block email spam).

2. When the mobile receives a call, t...
