It explains what has been specified, how to use the existing standards and what are their necessary evolutions for later phases. After providing an overview of data management in CS1, the CCITT CS1 SDF-SCF protocol (i.e. the User Data Manipulation INAP ASE) is presented. The stress is especially put on the shortcomings of the recommendation in regard to the requirements of services such as UPT or VPN. We first explain why a Directory solution has been preferred to other approaches. Then we give an overview of the operations (Bind, Search, ModifyEntry) to be included in the Q.12xx recommendations. The underlying information model is briefly presented. The key concepts of this model are introduced (object orientation, hierarchical structure...), with a special attention to the aspects which impact the protocol (e.g.. attribute definitions, object naming ... ). Then each operation is presented with the protocol elements used to construct its argument and result (attribute value assertions, filters, scope ... ). The description of the operation procedures serves as a means for explaining how the Information Model description impacts the behaviour of the SDF when processing one of these operations. Security issues and their impact on the protocol are also dealt with. After having described the database operations, we show the simplifications brought to the X.500 Directory Access Protocol (DAP) (e.g. aliases, ciphering, ...) and the still outstanding issues (e.g. set-to default mechanism, permitted values,...) To clarify the use of the X.500 operations and to support the findings of ITU-T in regard to this choice, a set of realistic examples is provided, based on the UPT service description. It is an opportunity to show how complex requests can be formulated using a Search operation with a combination of scope and filter mechanisms or an ModifyEntry operation with multiple actions. Finafly we discuss the evolution of the SCF-SDF interface for CS2 and upwards. We show the limitation of this kind of interface for supporting inter-network signalling procedures. We try to provide the needed improvements of the SCF-SDF interface. We also open the discussion on data distribution and on the potential use of the Directory System Protocol (DSP) for supporting the SDF-SDF interface.","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125167611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For rapid service introduction, the development of advanced IN operations functions must keep up with service creation. This paper describes advanced IN service operations functions, such as advanced IN surveillance and network-wide testing, and operations scenarios, which are a kind of logic program, execution and creation environments that allow rapid development of operations functions.","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130730363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They will do so by increasing their use of computer and communications technology on a large scale. This provides new markets for telecommunications operators, but also challenges them to tackle problems like for example integrating the historically separated fields of private and public (tele-) communications. The advent of TASC within ITU-TS is a sign of increasing attention for this subject. The Intelligent Network (IN) has separated control and switching functions, using telecommunications functionality s well as computer functionality in a public environment. Computer Aided Telecommunications (CAT) uses telecommunications and computer functionality in a private environment, to enble businesses to deal with incoming and outgoing traffic in a more efficient and effective way. With this contribution PTT Research, the research organization of Royal PTT Netherlands (KPN), presents the results of a project that studies the mutual impact of CAT and IN. The project has the purpose to find today's technical restrictions in both CAT and IN that may prevent realization of new services and applications based on CAT and IN, and aimed at integrated private/public telecommunications.","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117312353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Siemens was engaged during the whole study period in the specification of the IN recommendations and ensured a continuous feed back of IN Capability Set 1 standardisation results into the company's ongoing IN product development concerning Intelligent Networks. The Siemens IN systems, which will be delivered one year after approval of IN CS1 recommendations, are compatible to IN CS1, i.e. the design of these systems has been based on IN CS1 recommendations. Besides naturally enhanced capabilities compared to preceding systems one of the essentially new feature of these products is the support of the ETSI Core INAP. It is to note that the Siemens pre-CS1 IN systems as well as the IN CS1 conforming systems comprise several system components and capabilities which are additionally to IN CS1. This results from the fact that several essential parts of an IN system are not specified within those recommendations, i.e. currently not standardised capabilities like for example: - service creation environment, - service management services, - IN system management services, - service provider administration services, - service subscriber administration services, - etc..","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123620940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Minetti","doi":"10.1109/INW.1994.723275","DOIUrl":"https://doi.org/10.1109/INW.1994.723275","url":null,"abstract":"This contribution which presents work done within EURESCOM Project P103 \"Evolution of the Intelligent Network\" addresses the question of service independence, defines the notion of Service Component and discusses the interaction between the two domains of a telecommunications system, indicated as \"Service Domain\" and \"Network Domain\", in terms of a shared knowledge, represented by the Network Resource Model. A service can be viewed as a set of elements, termed Service Components, and, optionally, some 'glue\" logic that binds them together. Using concepts of set theory, we can say that a set intersection between services will yield the elements that are common to all services, to some services but not to all, or to only one specific service; this structures Service Components in a hierarchy of service independence. Service Components can be described in terms of Role Models, by OORAM language: this methodology also offers guidelines to extract Service Components from an overall high-level description of a service. An example of Service Component with a high degree of service independence is Connection Management. This component is of particular interest also because it lies at the \"boundary\" between the Service Domain, comprising all functionalities, concerned with the provision of an end-user service, and the Network Domain, compnising the functionalities related to the use of network resources: the \"core\" of the interface between these two domains is offered by Connection Management. The analysis of Connection Management shows that the interaction between Service Domain and Network Domain has to be based on a shared knowledge between the two, and that the most significant element of this knowledoe is the information model of network resources. This In Network Resource Model has to capture those aspects of the network that are relevant for services, hiding as much as possible of the underlying complexity. Some emerging resource modelling approaches are analysed.","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128373060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presentation is based on work that has been carried out in Eurescorn project 103 (PI03). In P103 Service Creation and Composition Guidelines have been developed. The guidelines define an object oriented method for the analysis and design of future IN services. The method is based on role modelling and on the use of Message Sequence Charts (MSC) and SDL-92 to specify behaviour. A role model is a specification of one elementary task (concern) of a service. Several role models can be combined to arrive at object types for the complete service. We call this combination synthesis. The guidelines have been used to analyse a Video Conference Manager. The conference manager has the overall control of a multiparty video conference. Some of the role models for the conference manager are discussed, and a simple example is presented to show how the role models can be combined in order to derive object types for the conference manager. Our results indicate that role modelling is a natural and efficient way to cope with service development. Role models are also well suited to identify similar problems in different services at an early stage of analysis. Therefore role models provide a good basis for reuse. In P103 our aim is to define reusable service constituents by following the guidelines. The principles of role modelling were originally presented by professor Trygve Reenskaug et al. (University of Oslo). The authors would also like to thank Bengt Jensen, Norwegian Telecom Research, and Carla Capellman, Deutsche Bundespost Telekom for their contribution to the results in P103.","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124497109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instead, we had to settle for a smaller scale priminary research. In order for this research to be a part of the whole implementation cycle, if any, we chose the rapid prototyping approach. The first prototype serves several purposes, which include: analyze CS-1 draft recommendations, draw the requirements and model for Service Creation, provide tools for service design prior to major implementation activity. The first prototype was built using a production system. A production system helps the user concentrate on the knowledge of the nature of the domain, instead of programming details which usually include \"flow of control.\" The prototype mainly modeled the aspects of Global Functional Plane with some DFP aspect of the basic call process which were necessary for the call/service simulation. Eight of the CS-1 SIBs, including the BCP SIB, were implemented in the prototype. An X/Motif-based graphic editor (for editing a GSL) and a graphic telephone/network simulator (for demonstrating the behaviour of the service defined by the GSL) was built independent of the prototype and losely combined via UNIX stream sockets and a simple parser.","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114247666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
