Wta architecture in mobile computing

Mobile Communication.

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.

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. Framework-three components 1. Within a real time environment. A repository storehouse or warehouse provides persistent client side storage for WTA app. The WAP gateway can enforce the security policy of the telecommunications service. An app. The resource manager of the WTA user agent allocates memory in the repository and always aware of the amount of available space. The channel and associated resources can be loaded into the repository by the following methods -The application can be reinstalled into the repository during manufacturing or during subscription process at a customer care center. WTA application programming interface The WTA application programming interface consists of two components: An event model- allowing the application to learn about and take action on telephony actions. A subscription interface- allowing the application to initiate and control telephony operations Telephony events- when user makes a call or a incoming call is received, the WTA network layer generates a sequence of events.

WTA is an application framework for telephony services. The WTA user agent has the capability for interfacing with mobile network services available to a mobile telephony device, that is, setting up and receiving phone calls. Figure 6. The WTA user agent receives network events that can be bound to content, thus enabling dynamic telephony applications. Network events available to the WTA user agent are the result of actions taken by services running in the WTA user agent itself. Telephony events initiated from outside the device are also passed to the WTA user agent and the network text message events. This library allows WML authors to include click-to-phone functionality within their content, to avoid users typing the number by using the default MMI.

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.

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.
