An automated registration service supported on an application server that interoperates with an IMS (IP Multimedia Subsystem) core network is configured to dynamically register and deregister devices that are all associated with one or more commonly-utilized phone numbers. The service may assign the phone number to registered devices and, in contrast, un-assign the phone number from deregistered devices. The registration and deregistration of the devices may occur based on the amount of interaction with the device and other real-time contextual information. Furthermore, the automated registration service intelligently determines which registered devices to forward incoming video and/or audio calls to based on various contextual information, including the capabilities of device, identified location of a user, user preferences, etc. By intelligently selecting which devices should receive an incoming call, unnecessary use of bandwidth, data, and resources (e.g., battery power) can be reduced.

Automatic forwarding of incoming calls based on user interaction with devices

A device state service supported on an application server is disclosed herein. The device state service is configured to dynamically monitor a device state across devices, and particularly monitor whether or not a device is currently active (e.g., incoming or outgoing ringing, incoming or outgoing busy signal, audio and/or video call in progress, etc.) The active device transmits device state data along with context data and sensor data (collectively 'real-time data'). The inactive (or subject) devices may likewise transmit real-time data to the device state service. The device state service determines an action for the subject and/or active devices to perform based on the received real-time data. For example, when a user's smartphone is currently active (e.g., a call in-progress), the user's tablet may enter a power save mode to save resources.

Notifications to all devices to update state

An automatic response service supported on an application server that interoperates with an IMS (IP Multimedia Subsystem) core network is configured to dynamically generate responses to unanswered incoming telephone calls to a user's computing devices that are customized for the calling party based on monitored activities of the user, device capabilities and state, and related context. The automatic response service can monitor the user's interactions across a range of computing devices to identify a device with which the is actively engaged. Data from device registrations with the IMS core network can indicate current device capabilities and device state such as peripheral device configuration and network connectivity. Along with call data such as caller ID, the monitored user activities and device information enable the service to automatically respond to incoming calls on behalf of the user with information that is meaningful and contextually-relevant to the calling party.
