| Over the last few years, significant evolutions such as the mobile phones' enhanced web-browsing capabilities and the technical incursion of Web major players into the Telco world (e.g. Google, Facebook) have reduced the gap between Telecom and Web worlds. In this context, converging IMS and Web service platforms has become a key challenge that needs to be addressed by both Web and Telecom players. Several interesting solutions, illustrating different convergence approaches, have been proposed so far. Unfortunately, none of them has been able to provide an efficient way to set up end-to-end converging services. Indeed, Web-based applications are synchronous, as they rely on HTTP. On the other hand, IMS services can be provided in both asynchronous and synchronous modes. We define synchronous applications as services in which each provided resource or piece of information has to be explicitly requested by the consumer and asynchronous applications as services that can notify their consumers anytime they need. But recently, the W3C and the IETF have released new standards (HTML5 and Websocket protocol), introducing important evolutions in the Web paradigm. In particular, the Websocket technology allows a native support for asynchronous Web applications. Our proposal is a converging framework (called WSE, standing for Websocket Enabler) that takes advantage of this new technology to achieve end-to-end service convergence. |
