Voice Message Retrieval by Contact and Missed Calls

The patent segments the voice message retrieval system into multiple access methods: chronological retrieval and contact-based retrieval. The voice messages are organized into different groups (received messages, missed calls, contacts) that can be accessed independently. This allows users to choose the most efficient retrieval method for their needs without complicating the overall system architecture.

The patent adds a new dimension to message retrieval by organizing messages not only by time (chronological order) but also by contact information. This creates multiple access dimensions - users can retrieve messages chronologically or by searching through contact-based organization, enabling efficient non-chronological retrieval without fundamentally redesigning the system.

The patent segments the voice message storage into multiple organized groups including received messages, missed calls, and contact-based categories. Each group maintains its own structure while being part of the overall system. This segmentation provides flexible organization by contact and call type while keeping individual group structures relatively simple.

The patent creates a universal retrieval system that can access voice messages through multiple organizational schemes simultaneously. The same message storage infrastructure supports both chronological access and contact-based access, making the system versatile without requiring completely separate storage structures for each access method.
