Streaming method for transmitting telephone system notifications to Internet terminal devices in real time

摘要

In the course of an application involving real-time notification of a client (PC(CC)) by a telephone switching system (TS) a connection between the client (PC(CC)) and a server (CtC) is opened. Notification messages transmitted from the telephone switching system (TS) to the server (CtC) are adjusted and sent to the client (PC(CC)) in the format of a programming language code executable by the client's browser. The programming language codes are subsequently executed by the browser, whereby the respective notification messages are displayed at the client (PC(CC)). For transmission of the notification messages from the server (CtC) to the browser (PC(CC)) a streaming method such as HTTP streaming is used so that the connection remains open while notification messages are to be sent. The present method can be based on standardised protocols, entails little protocol overhead and allows for a facile treatment of security issues.
