Various embodiments relate to a cloud-based temporary app management system. In one aspect of the invention, a cloud service provides a temporary app from a vendor. The temporary app is a mobile application that is temporarily accessible on a mobile device when a designated event (e.g. a change in the location or surroundings of the mobile device, a particular type of data stored in the mobile device, etc.) is detected by a mobile device. The cloud service receives event information from the mobile device. The event information indicates an event detected by the mobile device. The cloud service then determines whether to make the temporary app accessible on the mobile device based on an analysis of the designated event and the event information received from the mobile device.

In one embodiment, a method for monitoring events in a home network is provided. A node receives a subscription request from a control point, wherein the subscription request indicates an interest in delayable eventing. A change is detected in an event variable. It is then determined if the control point can receive an event sent from the node. If the control point cannot receive an event sent from the node, an event notification regarding the change in the event variable is stored such that the event notification can be retrieved when the control point can receive communications from the node.

Delayable events in home network

In one embodiment, a method is performed at a control point (CP) in a network. An action is invoked to create a synchronization data structure on a media server that includes a content directory service (CDS) in the network, wherein the synchronization data structure includes a synchronization relationship describing a relationship between the CP and the CDS. Then an action is invoked to add synchronization pair information to one or more objects on the CDS. A change log is requested from the CDS. Then the change log is received from the CDS, wherein the change log contains information about changes to the one or more objects to which synchronization pair information for the CP was added.
