摘要:
A universal plug and play (UPnP) device makes itself known through a set of processes-discovery, description, control, eventing, and presentation. Following discovery of a UPnP device, an entity can learn more about the device and its capabilities by retrieving the device's description. The description includes vendor-specific manufacturer information like the model name and number, serial number, manufacturer name, URLs to vendor-specific Web sites, etc. The description also includes a list of any embedded devices or services, as well as URLs for control, eventing, and presentation. The description is written by a vendor, and is usually based on a device template produced by a UPnP forum working committee. The template is derived from a template language that is used to define elements to describe the device and any services supported by the device. The template language is written using an XML-based syntax that organizes and structures the elements.

Sending and receiving application or service data through an email transport for mobile computing devices occasionally disconnected from network connectivity. At a sending service or application, application or service data is intercepted from the application or service. The application or service data is packaged in an email message. The email message includes the application or service data within the email envelope and an identification of an application or service client to which the application or service data should be applied at a client computer system. The email message is sent through an email transport to a mobile client computer system which includes the application or service to which the application or service data should be applied. At the client the email message is intercepted. The data is extracted from the email envelope. The application or service client is identified. The data is routed to the appropriate application or service.
