ITU-T's internodal broadband signalling protocol

Broadband integrated services user part (B-ISUP) is an internodal signalling protocol defined by the International Telecommunications Union (ITU-T). Its purpose is to establish, maintain and release asynchronous transfer mode (ATM) connections in a public network, via the use of signalling messages. The initial release of B-ISUP was in February 1995, known as capability set 1 (CS-1). Since then, continued progress has been made extending the capabilities of B-ISUP with the development of CS-2. This paper provides an overview of the B-ISUP signalling protocol capabilities and describes its impact on the traditional Signalling System No 7 (SS7) architecture.     

Intelligent network/2: The architecture-The technicalchallenges-The opportunities

The Intelligent Network/2 (IN/2) architecture concept diverges from the traditional new service introduction approach by distributing call-processing capabilities across multiple network modules, by constructing network services with service-independent capabilities, and by using standard signaling protocols among the network elements. The IN/2 approach provides opportunities to implement new services while reducing the service introduction interval. The IN/1 architecture provides new-service introduction from a centralized point, allowing users throughout a wide geographic area to have access to the service simultaneously. The IN/2 concept extends the IN/1 approach and sharply reduces the new-service introduction interval. IN/2 applies the premise that multiple network services or service features can be constructed from a set of reusable network capabilities, which apply to many services and are therefore independent of a particular service application. An overview of the IN/2 architecture is presented, highlighting the key technical issues     

Consideration on common channel signaling evolution for globalintelligent networking

With the evolution of digital networks and intelligent network (IN) capabilities, the role of common channel signaling has become more and more important. In respect to IN, common channel signaling would play a significant role not only inside one network but also over multiple networks. International credit card validation and internetworking for digital mobile services represented by GSM (Global System for Mobile Communications) are examples which utilize internetwork signaling capabilities in the framework of the initial-phase IN. Enhanced service providers (ESPs) may access the public network through the common channel signaling interface to make use of the IN capabilities, as is being discussed in terms of ONA (open network architecture) or ONP (open network provision). This paper first identifies various scenarios where internetwork signaling interactions would take place in the framework of IN in the forthcoming era. It then identifies various requirements to cope with these scenarios. It finally discusses the directions for evolution of common channel signaling toward global intelligent networking     

The intelligent network concept

The intelligent network (IN) concept evolved from the networks which are planned or in existence in 1988 to provide network services such as the 800 service. The IN architecture will require an expansion of the capabilities which recognize the need for specialized processing and formulate a query to a database system. The expanded capabilities, along with an expected increase in the number of calls requiring special processing, place greater demands on system resources. The distributed nature of service implementation, along with the complex interactions among services, requires advanced, highly efficient operations. The authors describe the IN architecture and the process of creating a service in that environment. An illustrative example is include     

Intelligent network evolution issues

The exchange telephone industry has developed a concept of future intelligent network characteristics that is gaining widespread acceptance. The concept is characterized by a service-independent architecture, integrated operations and service management systems, and programmable network entities. The full realization of this vision will require major advancements in the control software and signaling capabilities of existing network elements and operations systems, as well as the development of entirely new systems. Evolutionary strategies are discussed that can move the embedded network toward the ultimate goal and begin to achieve many of the benefits of the future vision in the near term. In particular, an intermediate intelligent network architecture called IN/1+, which could be implemented by 1991, is presented. IN/1+ is focused on circuit-switched capabilities and provides a significant movement toward the intended IN/2 architecture with a reasonable commitment of industry resources     

Evolutionary trends in intelligent networks

A number of groups are currently developing technologies aimed at evolving and enhancing the capabilities of intelligent networks. In this article we discuss three of these initiatives: PINT, Parlay, and IN/CORBA interworking. The IETF PINT work addresses how Internet applications can request and enrich telecommunications services. The Parlay consortium is specifying an object-oriented service control API that facilitates the access, control, and configuration of IN services by enterprise IT systems. The OMG's IN/CORBA interworking specification enables CORBA-based systems to interwork with existing IN infrastructure, thereby promoting the adoption of CORBA for the realization of IN functional entities. We address how all three of these technologies could be deployed together in order to provide a basis for a more flexible and open IN architecture. We also identify a number of common trends and potential pitfalls highlighted by current work on the evolution of IN     

International standards for intelligent networks

An overview of the current state of intelligent network (IN) standards as described on CCITT's capability set 1 (CS1) is presented. The key to the success of CS1 lies in it being simple enough to be realizable with limited impact on existing software technology and network signaling, rich enough to provide a nontrivial, commercially deployable, initial set of services, and open-ended for growth, both in terms of service richness and penetration, and new capabilities enabled by new technologies. The objectives of IN and CS1, the main characteristics of CS1, and the framework and directions for IN evolution are discussed     

Intelligent network requirements for personal communicationsservices

It is shown that a moderate set of capabilities within the service switching point (SSP), service control point (SCP), and intelligent peripheral (IP), which are the intelligent network (IN) components directly responsible for the real-time execution and control of end-user services, can engender a wide range of end-user personal communication service (PCS) features. These capabilities could be used as the starting point for an economic analysis of IN implementation costs versus service worth. From a very large target set of call model trigger check points (TCPs), the dozen or so identified in the CCITT Capability Set 1 are shown to be sufficient. The SCP and IP functional entity actions identified are also sufficient to support PCS core network functions
