IMS Automatic Call Response Service for Contextual User Activity

The patent introduces an automatic response service as an intermediary component that sits between the IMS core network and users. This service automatically monitors user activities across multiple devices, analyzes contextual information, and generates appropriate responses without requiring direct user intervention. The intermediary handles the complexity of data collection, analysis, and response generation, while users simply benefit from the intelligent responses.

The automatic response service enables the system to serve itself by autonomously monitoring user activities, determining device states, and generating contextualized responses. The service independently collects data from device registrations, monitors user interactions, analyzes activity contexts (such as gaming, meetings, or poor network conditions), and formulates appropriate automatic responses without external intervention, thus reducing the need for manual configuration and complex user-side processing.

The system performs preliminary actions by establishing device registrations with the IMS core network in advance. Each device registers its capabilities and state before being needed for call handling. This pre-registration process allows the automatic response service to have immediate access to device capability information without needing to collect and process all possible data in real-time, reducing the data processing burden while maintaining accurate device identification.

The automatic response service implements feedback mechanisms by continuously monitoring user activities and device states, then using this information to dynamically adjust and generate appropriate responses. The service receives feedback from device registrations about current device capabilities and network conditions, and uses this feedback to optimize response generation, ensuring that responses are both effective and timely.
