In this unit defined the mobile Internet-wireless communications and the wired internet Today mobile network supports- call forwarding, call waiting and call conferencing In this unit describes how WAP Wireless Telephony Applications WTA provide a bridge between wireless telephony and data. The fig. Illustrates the end-to-end system for delivering these applications. Requires the presence of the WTA app. Framework-supports the real time needs of telephony app. And optimize the low bandwidth to distribute content to the mobile client.

WTA Architecture. Browsing the web using the WML browser is only one application for a handheld device user. Say a user still wants to make phone calls and access all the features of the mobile phone network as with a traditional mobile phone. WTA is a collection of telephony specific extensions for call and feature control mechanisms, merging data networks and voice networks. The WTA framework integrates advanced telephony services using a consistent user interface e. A network operator can reach more end-devices using WTA because this is integrated in the wireless application environment WAE which handles device-specific characteristics and environments. WTA should enable third-party developers as well as network operators to create network-independent content that accesses the basic features of the bearer network. However, most of the WTA functionality is reserved for the network operators for security and stability reasons. A push can take place without prior client request. The content can enable, e. Content are either channels or resources. Resources are loaded using WSP or are pre-installed. A channel comprises references to resources and is associated with a lifetime.

WTA is a collection of telephony specific extensions for call and feature control mechanisms, merging data networks and voice networks. It is an Extension of basic WAE application model with following features —network model for interaction client requests to server event signaling: server can push content to the client — event handling table indicating how to react on certain events from the network client may now be able to handle unknown events —telephony functions some application on the client may access telephony functions WTAI Wireless Telephony Application Interface includes: —Call control —Network text messaging —Phone book interface —Event processing Security model: segregation —Separate WTA browser —Separate WTA port WTA logical architecture The client is connected via a mobile network with a WTA server , other telephone networks and a WAP gateway. A WML user agent running on the client is not shown here. The client may have voice and data connections over the network. Other origin servers can be connected via the WAP gateway.

Tests, evaluations, and solution comparisons in complex use cases are often realized by creating a testbed for a domain of use cases and solutions. Web-based testbeds add key advantages like results sharing, remote test execution, and collaboration. Focusing on their research objectives, creators see their testbeds as a means to that end. The resulting web-based testbeds are similar in structure and functionality, but there is no common architecture supporting their creation, introducing redundant design efforts. Therefore, we determine structural similarities based on insights into the architecture of current web-based testbeds, from which we derive a generic web-based testbed architecture. This framework of reference will help to develop future testbeds focusing on the testbed domain instead of reinventing general testbed functionality.

It is a protocol designed for micro-browsers and it enables access to the internet in mobile devices. It enables the creation of web applications for mobile devices. In ,. In , WAP forum was merged with various other forums in the industry resulting in the formation of. The user opens the mini-browser in a mobile device. He selects a website that he wants to view. The request reaches to a specified web server and it processes the request just as it would have processed any other request and sends the response back to the mobile device through WAP gateway in WML file which can be seen in the micro-browser. The following advantages for wireless network operators, content producers, and end users were put out by WAP when it was first introduced in Operators of wireless networks and mobile phones: WAP was created with the intention of enhancing already-existing wireless data services, such as voicemail, and facilitating the creation of new mobile applications.
