Abstract

The communication network is in a rapid transition not only in terms of technical respects, but also in terms of user requirements for new kind of intelligent services. Especially, the timely provision of the new services is becoming crucial to the network operators to fulfill the user requirements. This transition of communication environment is resulted in the buildup of new communication network infrastructure, namely NGN, which allows the third-party application provisioning by opening the network capabilities. Opening the network capabilities can be achieved by defining an open API that resides between the application sub-layer and the service component sub-layer, and makes it possible for the third-parties to program the network by exposing the functionalities of network element outside world through well-defined open API.

The Parlay API is an example of the open API. The Parlay Working Group, which consists of the various telecommunication equipment manufacturers and the computer platform companies try to establish the new open programmable API and promote for this specification to be adopted in implementation of commercial products. Also Parlay API pursues to define the integrated API so that it can control the voice, video and data networks in the same manner. In this presentation, the technical trend of open services and Parlay API will be presented.
