Abstract:
1. A method of establishing communication services using web service operations over a network comprising: establishing an application session association between two communication endpoints across the network by way of a session service, and wherein said application session includes web services which are used as meta-services to provide a service oriented extension framework to bundle base services and include new services in communications; addressing services on at least one of said communication endpoints by way of an addressing service; establishing and negotiating a media transmission relation between the two communication endpoints by way of an eventing service such that media at a first endpoint is exposed as a event source service and a second endpoint subscribes to receive events from said event source service and provides an event sink to said event source, wherein said session service, addressing service and eventing service are arranged in a single stack protocol, wherein said single stack protocol is specified by web service Web Service Description Language (WSDLs) and eXtensible Markup Language (XML) schemas; controlling a media transmission relation between the event sink and the event source by way of an event subscription manager service that is communicated back to an event subscriber by the event source in its acknowledgement message of an event subscription; and transmitting media data between the event source and the event sink by way of a transport protocol which is separate from said application session, and wherein communications signaling is entirely based on two-way web services interactions.
