Abstract: A communications method and system and more particularly, to systems, methods and apparatuses for universal user-to-user communications. A communication system is described which uses a Universal Identification Number (UIN) that identifies each user on the system, encapsulating data that represent the user him or herself. Such data may include, the user's current physical geolocation on the globe; current status (busy, reachable, not reachable); current active endpoint to reach at and preferred method of reach; and an aggregation of all endpoints at which the user can be reached, and their geolocation. The described method and network system thereby can dynamically introduce, adapt, and communicate services (in essence personalize) to each user based on their current location and status. Thus, a user may communicate with another user efficiently without the need to know all of their endpoints or without the need to have multiple communication attempts on multiple devices.
