Abstract
A mobile device executes a background process under an on demand model that queries a remote service exposed by a mobile broadband network to receive status updates as to the capabilities of devices, such as the ability to stream video, that are associated with contacts that are stored on the mobile device. When a mobile device user invokes an action like using a dialer application that causes a contact to be displayed on the device's user interface (UI) such as in a contact card or contact list format, the background process immediately retrieves status for that contact card or list. While waiting for the status retrieval to complete, the background process will trigger the display of a temporary UI on the mobile device which can show either unknown capabilities status or show the most recently retrieved status that is read out of a cache.
