The document describes a context management infrastructure and context manager for mobile environments. The context manager is a central element that stores and manages context information from various sources to enable personalized services for mobile users. It allows context information to be queried and context-aware applications to subscribe to updates. The document outlines the prototype of the context manager and a use case where a contextual service uses the manager to suggest meeting plans to friends based on their locations and statuses.
