Abstract
We have built a SoftBridge prototype within a JAIN (Java APIs for the Integrated Network) SLEE (Service Logic Execution Environment). A SoftBridge is a semi-synchronous multimodal IP (Internet Protocol) -based communication system and the first prototype has been built for deaf telephony. This research addresses service life-cycle management for a SoftBridge with carrier grade reliability. An approach is proposed that carrier grade reliability support for a SoftBridge is provided by moving it into a JAIN SLEE. A JAIN SLEE is a general application server, which provides execution and management environment for telecommunication services. An empirical evaluation methodology is adopted to verify that JAIN SLEE enables carrier grade support for a SoftBridge. This work includes the development of functions of a SoftBridge and life-cycle management of a SoftBridge within a JAIN SLEE. Current work is busy in developing multimodal media adaptation functions of the SoftBridge prototype. System test, experiments with PBX (Private Branch Exchange)/PSTN (Public Switched Telephone Network) and evaluation of the SoftBridge prototype will be carried out in the next steps. Carrier grade reliability enables a SoftBridge to access the PSTN. A highly reliable SoftBridge could bring more new value-added services for telecom providers. Using a SoftBridge as an example, we also can learn how to go about carrier grade enhancement for IP-based communication applications in the telecoms domain.
