Abstract:
1. A method of providing reachability status to subscribers comprising: presenting a plurality of reachability states, each reachability state representing an aggregate accessibility of a user derived from a plurality of statuses each corresponding to one of a plurality of network elements associated with the user; for each of the reachability states, presenting at least one reachability rule, each reachability rule corresponding to one of the network elements and indicating a status for satisfying the reachability rule; receiving a selection of one or more of the reachability rules; accessing a central storage maintaining the statuses corresponding to the network elements; identifying an ordering of the reachability rules; until a current reachability status is selected: identifying one of the reachability rules based on the identified ordering; determining whether the identified reachability rule is satisfied; and if the identified reachability rule is satisfied, selecting the reachability state associated with the identified reachability rule as the current reachability status; determining one or more subscribers for receiving the current reachability status; and communicating the current reachability status to subscribers.
