Abstract: In one embodiment, a network device enforces entitlement rules based on call control traffic received. The call control traffic is received at the network device from an application associated with a first user for a second user. The network device determines identification information for the first user and/or the second user. The network device then determines an action to take based on an entitlement policy associated with the first user or the second user. The action is then performed. The network device enforces the entitlement policy without any modification to the application to cause the call control traffic to be routed through the network device. The network device is in the call control path but does not appear to be a participant in the call to the first application.

Abstract: A method and system to provide a notification is described. The system may comprise a first mobile device including a positioning component to determine when the first mobile device is proximate at least one predefined zone (e.g., enters, remains within or leaves the predefined zone), and a location data compiler to compile location data which includes a zone identifier corresponding to the at least one predefined zone. The first mobile device may further comprise a device identifier and a transmitter to send the location data and the device identifier to at least one recipient associated with the at least one predefined zone. The system may include a second mobile device associated with the at least one recipient and including a receiver to receive the location data from the first mobile device, and a display to display the location data and the zone identifier on the second mobile device.

Abstract: A customizable mechanism is provided for determining and reporting the overall reachability of a user based on the current statuses of a variety of network elements associated with the user, such as devices or applications that a user may use to communicate with others. The system can evaluate customizable reachability rules to determine an overall reachability status for the user. The system provides for distribution of reachability status and presence statuses of network elements to authorized subscribers.
