To form a foundation for the discussion, the status of current international services is reviewed using a few well known examples. Having established the current service environment, the drivers behind the move from national to pan European service provision are presented. The rest of the paper is then dedicated to the study being carried out by Eurescom into enabling pan European IN services. Firstly the choice of a set of candidate services for initial investigation is explained. Based upon the requirements for these services, the various implementation issues are discussed. Having highlighted the issues, a series of implementation options are presented. Finally the presentation concludes by highlighting the current findings of the Eurescom project. It is then intented that a question/discussion forum be opened in which the options for pan European and international services can be debated.","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"43 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":"128313964","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}

It is well suited for large nonhierarchical meshed networks. An RSF (Route Switching Function) is implemented in a switch called RSP (Route Switching Point), which may be physically identical with an SSP. If the primary route to the destination RSP is blocked, the RSP starts a query via the CCS7 to an external processor called RCP (Routine Control Point), which may be physically identical with an SCP. For each link within its domain, the RCP determines the link occupancy from the time intervals between previous overflowing calls. For a given call attempt, the RCP computes path costs for all allowed routes. The cost is defined in terms of the expectancy of the number of lost calls in the future under the assumption of a certain traffic distribution. The response of the RCP is either an extended \"Connect\"-message containing the optimised routine instruction or a conventional \"Reject\"-messagge. If the DR system contains several RCPs, each RCP shall broadcast its current link occupancy data to all other RCPs in update intervals of 10 sec. For this distribution, a satellite based transmission scheme is recommended. There is one central processor within the DR system named RMS (Routine Management System). The RMS uses destination specific traffic data and network configuration data to compute the tables used by the RCPs during call processing.","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"14 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":"132790183","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}

Clearly, the signaling between SSP and SCP causes some additional connection establishment delay. There is often signaling in the call termination phase. This signaling is important because of the traffic it generates and a delay it causes. Automatic call gapping, user impatience and time-outs can cause call abortion some of which is experienced by the caller as blocking. In this talk a simple phenomenological method is presented for obtaining end-to-end delays and some blocking probabilities. The method starts from message sequences and assigns work loads to transmitting or processing the messages. In Basically the whole signaling network is approximated by a single queue and a load dependent delay. There follows a discussion of what and how information of the signaling traffic characteristics and of the node architecture can be used in this simple model intended to give a formula for end-to-end delay to be used in the dimensioming process. Finally some scenarios which can degrade Grade of Service of an Intelligent Network are described as another aspect of performance modeling.","PeriodicalId":156912,"journal":{"name":"Workshop on Intelligent Network","volume":"25 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":"124973723","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}

Visser","doi":"10.1109/INW.1994.723299","DOIUrl":"https://doi.org/10.1109/INW.1994.723299","url":null,"abstract":"The IN SSP will play a key role in the telecommunications business in the mid to late 1990s. The business rationale for this is considered in two parts: the overall market forces driving requests for IN and therefore IN SSPs, and the translation of these market forces into business opportunities. The key market forces are the ever increasing demands for services, rising demand for service custornization, and increasing depth of competition in the rapidly evolving telecommunications marketplace. In the evolution of the public network services architecture, there is a clear trend toward increased intelligence outside the switch. AIN is the technology drive that will support this trend for the next decade. AIN provides the means to expand beyond traditional switch-based services into the provision of services that fall naturally into a centralized structure and into a range of services of individually limited penetration for which a switch-based implementation is usually unjustifiable. The translation of these market forces into business opportunities requires complete service solutions and complete infrastructure solutions. These will enable mutual leverage of service and network experience to provide the best value to the end customer. This will be achieved through vendors providing open platform and technology solutions ensuring global market and business effectiveness, driving evolution from services perspective, and partnering with key, strategic customers to achieve the mutual benefits of IN. Services drive implementation: customer requirements define implementation order. Ongoing customer interactions are vital to ensuring correct service-based prioritization of SSP rollout. The interactions solidify customer value and consequently ensure that IN SSP value is realized. The IN SSP is the place at which distributed service logic interacts with the call. This makes the IN SSP the linchpin that keeps the service and the call together. A key point in the evolution of the intelligent network is that the IN SSP software will become the network's \"operating system\" for services. As such, IN SSP software will experience regular upgrading and enhancement. This ongoing process is already seen in North America by the progression of Bellcore AIN Release 0.0, 0. I and 0.2, with discussions already underway on subsequent releases. It is equally seen internationally by the progression of' standards for ITU-T CS- 1 and CS-2, and ETSI INAP.","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":"122054425","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 main impetus for IN is its ability to assure service transparency in a multi-vendor environment and, at the same time, to provide a flexible platform for network providers to create and introduce new services quickly and easily. The IN standards activity in ITU-T is based on a service-driven approach and the main objective is to ensure that the standards developed today are easily evolvable to address future services and network capabilities. ITU-T completed Capability Set -1 (CS-1) in 1992 which is a subset of IN capabilities and addresses the near-term requirements of both manufacturers and network operators. Currently, ITU-T Study Group (SG) 11 is addressing the issue of refinements to CS-1 to ensure multivendor interoperablity. SG 11 plans to complete CS-1 refinement work by September 1994 in order to approve the revised CS-1 Recommendation in early '95. ETSI SPS-3 recently completed the Core INAP draft standard which addresses some of the refinement issues. ETSI Core INAP is under consideration in ITU-T to augment CS-1 INAP. In North America, Bellcore has developed AIN 0.1/0.2 Generic Requirements which are functionally a subset of CS-1. SG 11 is also developing CS-2 Recommendation and plans to complete CS-2 work by April 1995 in order to approve the CS-2 Recommendation in 2nd half of '95.

To enable this, much emphasis has been placed on the development of an architecture that primarily focuses on (1) a Call Model to which all Service Logic Programs (SLPs) adhere, (2) the Service Logic Execution Environment (SLEE) on which the SLPs execute, and (3) the Service Creation Environment (SCE) on which the SLPs are created. However, the mechanisms and operations aspects of deploying such services have frequently been overlooked. Service deployment is defined as the complete process of loading the SLPs and relevant data onto the SLEE, and the creation and development of Operations Systems applications to administer the SLPs so that services can be made available to the customer, billed for, and maintained. In this talk, we first examine the critical role of operations support of a service, and based on our experiences in developing operations systems for GTE's IN testbed to achieve rapid provisioning and deployment of services, we propose necessary requirements to truly achieve \"rapid service deployment.\" We introduce the concept of Service Package as the end product of the SCE and as the input to the deployment Operations Systems. We propose that the Service Package be standardized and so treated by the Operations Systems. Much efficiency can be attained by this as the deployment process is repeated for each new service. We also propose that all IN services adhere to a standardized Information Model (Management Information Base), akin to adherence to a standardized Call Model. In addition to being the underlying basis for constructing the Service Packages, the Information Model must be consistently followed in developing the SLPs, in preparing Operations Systems applications, and in deploying services.","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":"132362397","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 the UPT to UPT case and for any other case, when a single IN service is invoked twice, it is proposed that the call shall be treated by a single SCF instance, otherwise the call shall be treated by two coupled SCF instances.
