Providing an Aggregate Reachability Status

A device for providing reachability status to subscribers comprising:

• a plurality of network elements associated with a user;
• and
• a user interface operable to:
• display a plurality of reachability states, wherein each reachability state represents an aggregate accessibility of the user derived from a plurality of statuses each corresponding to one of the plurality of network elements;
• display at least one reachability rule for each of the reachability states, wherein each reachability rule corresponds to one of the network elements and indicates a status for satisfying the reachability rule;
• and
• transmit a selection of one or more of the reachability rules to a presence aggregation system, the presence aggregation system comprising a memory and operable to:
• receive the selection of one or more of the reachability rules;
• access a central storage maintaining the statuses corresponding to the network elements,
• identify an ordering of the reachability rules;
• until a current reachability status is selected:
• identify one of the reachability rules based on the identified ordering;
• determine whether the identified reachability rule is satisfied;
• and
• select the reachability state associated with the identified reachability rule as the current reachability status if the identified reachability rules is satisfied;
• determine one or more subscribers for receiving the current reachability status;
• and
• communicate the current reachability status to subscribers.

A non-transitory computer readable medium encoding logic for providing reachability status to subscribers, the logic operable when executed to:

• display 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, display at least one reachability rule, each reachability rule corresponding to one of the network elements and indicating a status for satisfying the reachability rule;
• and
• transmit a selection of one more of the reachability rules to a presence aggregation system, the presence aggregation system operable to:
• receive a selection of one or more of the reachability rules;
• access a central storage maintaining the statuses corresponding to the network elements;
• identify an ordering of the reachability rules;
• until a current reachability status is selected:
• identify one of the reachability rules based on the identified ordering;
• determine whether the identified reachability rule is satisfied;
• and
• if the identified reachability rule is satisfied, select the reachability state associated with the identified reachability rule as the current reachability status;
• determine one or more subscribers for receiving the current reachability status;
• and
• communicate the current reachability status to subscribers.

• means for displaying 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;
• means for displaying at least one reachability rule for each of the reachability states, each reachability rule corresponding to one of the network elements and indicating a status for satisfying the reachability rule;
• and
• means for transmitting a selection of one or more of the reachability rules to a presence aggregation server, the presence aggregation server operable to:
• receive a selection of one or more of the reachability rules;
• access a central storage maintaining the statuses corresponding to the network elements;
• identify an ordering of the reachability rules;
• select a current reachability status comprising:
• identify one of the reachability rules based on the identified ordering;
• determine whether the identified reachability rule is satisfied;
• and
• select the reachability state associated with the identified reachability rule as the current reachability status if the identified reachability rule is satisfied;
• determine one or more subscribers for receiving the current reachability status;
• and
• communicate the current reachability status to subscribers.
