Samsung patents method to block calls before connection starts

Samsung has filed a patent for a system that checks incoming call numbers against a block list before the phone fully connects. If the number is blocked, the device sends a rejection message to the caller without performing the usual steps to establish a call connection.

Why it mattersThis approach could make call blocking more efficient by stopping the connection process earlier in the network handshake.

In the filing’s own words

An electronic device may include a processor, and a memory for storing instructions. When the instructions are executed by the processor(s), the electronic device can control that: a list of blocked call numbers is stored; a phone number related to a first message is identified on the basis of the first message for call reception being received; whether the phone number related to the first message is included in the list of blocked call numbers is identified; and, on the basis of the phone number related to the first message being included in the list of blocked call numbers, a second message for rejecting call reception is transmitted to an external device in a state in which at least one of operations for call connection is not performed.

What exactly they claim (claim 1)

1. An electronic device comprising: at least one processor comprising processing circuitry; and a memory configured to store a blocked number list, wherein the memory is configured to store instructions that, when executed individually and/or collectively by the at least one processor, cause the electronic device to: identify a number of an incoming call, based on reception of a message for the incoming call from an external device; control an IMS layer to acquire the blocked number list stored in the memory; control the IMS layer to identify whether the number of the incoming call is included in the blocked number list; and control to transmit a message rejecting the incoming call to the external device in a state in which operations for preparing establishment of a call connection are not performed based on the number of the incoming call being not included in the blocked number list.
