Abstract: A system and method of conference messaging between Universal Plug and Play (UPnP) telephony devices and Wide Area Network (WAN) devices is where a conference messaging session with WAN devices is initiated by at least one Telephony Control Point (TCP) via a session request which includes session information, media capabilities of at least one TCP, a list of WAN devices, and a subject of the conference messaging session. The conference messaging session is then established between the at least one TCP and the WAN devices by a Telephony Server (TS) in an UPnP telephony based home network based on the session request.

Abstract: A method and apparatus for sharing a memo using UPnP telephony. The method includes receiving a request for a memo service from one or more devices by a telephony server, receiving memo information to be shared from a first telephony control point by the telephony server, and notifying, by the telephony server, the received memo information to the one or more devices having made the request for the memo service.

Abstract: 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.

Abstract: 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.

Abstract: Health data measurement devices may be used in a UPnP home network to obtain health data and have the data stored in personal health records in an application hosting device in the network. Various types of devices may be used to access the data and to render the data on displays in the home network, such as televisions, using UPnP protocols. A health sensor device has an IP-LAN UPnP health service module and a possible a control point. An application hosting device, which stores and manages the health data, has a host UPnP health service module and may also have a control point. A remote device, such as a cell phone, may be used to remotely access health data on the application hosting device. A remote device description is dynamically generated by the hosting device based on a configuration set in a remote access service on the hosting device. The remote device description is generated dynamically (“on the fly”) as the remote device attempts to access data in the UPnP network.

Abstract: In one embodiment, a method for monitoring events in a home network is provided. The method includes receiving a subscription request from a control point, wherein the subscription request indicates one or more event variables to monitor for the control point. Then a change is detected in an event variable. Then, it is determined if the event variable has been indicated by the control point as an event variable to monitor for the control point. If so, then the control point is notified of the change in the event variable.
