Electronic Device Automatic Response Based on Sender Identity

The patent applies local quality by differentiating the automatic response behavior based on the sender's identity. The system checks whether the sender's contact number is in the user's contact book, and only sends automatic responses to recognized contacts. This selective approach allows the system to provide convenient automatic responses to trusted contacts while protecting privacy from strangers, thus resolving the contradiction between user convenience and privacy protection.

The patent implements periodic action by checking message confirmation status at intervals rather than continuously monitoring. The system checks whether a received message is confirmed within a preset time period, and only triggers an automatic response if the confirmation status changes within that period. This periodic checking mechanism reduces energy consumption compared to continuous monitoring while still maintaining timely response capability.

The patent applies parameter changes by using the contact book status as a filtering parameter. The system changes the response behavior based on whether the sender is a recognized contact (parameter change from unrecognized to recognized). This parameter-based filtering ensures that automatic responses are only sent to relevant contacts, maintaining message relevance while still improving overall response efficiency through automation.
