Apple's new patent has detailed a system that would use contextual information from a mobile phone like time zone and ringer silence status to determine whether the user is available for a call and display the information to friends.
According to TechCrunch, the new system will use information like battery life, location, time zone, ringer silence status and cell network strength to determine the user's availability for a phone call.
The new Apple patent details a system that would use all relevant signals from a mobile phone, including whether it's been placed in airplane mode, or set solely to vibration.
The information would be made available to contacts looking to connect on an on-demand basis, with the user of the phone sending status able to specify which contacts specifically should be able to have access.
