| Abstract | The liberalization and deregulation of the public telecommunication put the network and service providers in the competitive market environment. Additionally, a rapid introduction of new multimedia services is inevitable in this environment in order to occupy the leading position in the telecommunication world. Therefore, it is strongly necessary that telecommunication service architecture should be more scalable, flexible, and interoperable. Recently, distributed object-oriented technology is adopted in Intelligent Network (IN) [1]. In intelligent network, Service Switching Point (SSP) is more difficult to be changed than Service Control Point (SCP), and the number of SSP is greater than that of SCP. Therefore, CORBA-based IN implementation is tried from upper layer to lower [2]. Gradually, full CORBA implementation will be achieved. In the future telecommunication environment, mobile network is also expected to adopt distributed object-oriented technology for mobility management and call control [3]. Eventually, legacy TC systems and CORBA-based systems coexist in transition and interworking of them is indispensable. There are researches and specifications done by Object Management Group is used for transmission of signaling messages created by Mobile Application Part (MAP) and Intelligent Network Application Part (INAP) for service control. CORBA is being widely used as the appropriate infrastructure in a value-added telecom network. As a solution, TC/CORBA gateway performs conversion between CORBA IDL and TC application part such as INAP and MAP. Firstly, we develop TC ASN.1 to IDL translator, which translates TC ASN.1 specifications such as INAP and MAP into IDL. Secondly, we design and implement generic TC/CORBA gateway. It is based on interaction translation specification of OMG [5]. The building of generic TC/CORBA gateway requires TC/SS7 interfaces, TC-user facilities and generated IDL interfaces by a TC ASN.1 to IDL translator. In addition, it should support application location, dialog initiation, dialog maintenance and operation invocation [5]. The Generic TC/CORBA gateway supports time critical feature. In gateway operation, TC-user object is created by request from remote service operations. This method makes delay elements. We propose object pool mechanism to figure it out. This mechanism maintains the created TC-user objects in an object pool of CORBA domain. After this, object pool administrator manages binding of proxy objects at a gateway and TC-user objects in CORBA system. This mechanism enhances the response time characteristics and scalability. Generic TC/CORBA gateway can be used as an intermediate solution to the full CORBA environment with reasonable cost and short time for service development, deployment, and execution. … |
