26、y place; any time; through any chosen access mechanism. Service Providers are looking for a Management Framework that: radically increases customer satisfaction; and at the same time underpins a significant reduction in operating costs, for example through: - new technologies; - new business models;
27、 - and new operational methods. Services in this context are the traditional telecommunication use of the word which is really around applications such as: voice, messaging, etc., which in most industries are referred to as products. Whilst the title is Next Generation Networks (NGN) much of the cha
28、llenge arises from new business models and the effective operational delivery of those services, which in turn is high dependant on flexible and efficient Operations Support Systems (OSS) and processes. The present document focuses on these later management concerns rather than the networking and ap
29、plication aspects. ETSI ETSI TR 188 004 V1.1.1 (2005-05) 7 5 Next Generation Networks (NGN) The main sources of NGN frameworks and architectures are emerging from ETSI and the ITU-T. ITU-T has produced an overview ITU-T Recommendation Y.110 1 that provides a comprehensive view of the challenges that
30、 have to be addressed by NGN solutions. It focuses on: The conceptual overview of an NGN and the users. The enterprise (Business) Models that are needed to support the delivery of an NGN, with an emphasis on the multi-organizational models that will become more prevalent. A structural model of servi
31、ces, applications, and infrastructure components. Models and a set of examples. ETSI has produced ES 282 001 2 that provides a description of the overall functional architecture of NGN, The ETSI NGN functional architecture complies with the ITU-T general reference model for next generation networks
32、and is structured according to a service layer and an IP-based transport layer. The service layer comprises the following components: the core IP Multimedia Subsystem (IMS); the PSTN/ISDN Emulation Subsystem (PES); other multimedia subsystems (e.g. streaming subsystem, content broadcasting subsystem
33、, etc.) and applications; common components (i.e. used by several subsystems) such as those required for accessing applications, charging functions, user profile management, security management, etc. IP-connectivity is provided to NGN user equipment by the transport layer, under the control of the N
34、etwork Attachment SubSystem (NASS) and the Resource and Admission Control Subsystem (RACS). These subsystems hide the transport technology used in access and core networks below the IP layer. 6 Customer centric vision For Service Providers (SP) a critical business driver is improvement of the custom
35、er experience. Customer perception of an SP is driven by the amount of contact that they need to have, and the experience they have in achieving their objectives through these contacts. Poor internal processes, communications and complex information flows all lead to unnecessary visits, slow resolut
36、ion of customers issues and high levels of customer dissatisfaction. A number of key objectives are described in the following clause have to be realized for NGN to deliver and improve customer service. 6.1 Personalized Personalization requires a service and operational management design based on “U
37、sers“, not on the services they use, and a design that enables the customer to fully take control of their communication needs. Achieving this goal requires a user profile to record user choices that can be dynamically attached to wherever they chose to access their services. Networks and services w
38、ill need to recognize “Users“ not simply physical access points or terminal devices to configure their services. Some users may perform multiple roles e.g. home and business roles, and the personalization solutions will need to support individuals working in multiple roles e.g. set up call diversion
39、s based on roles selected, time of day, etc. The Customer is the role that contracts for the services offered by a service provider based on a contractual relationship. ETSI ETSI TR 188 004 V1.1.1 (2005-05) 8 The role of “customer“ will need to be recognized as the customer may be the only one permi
40、tted to perform some tasks such as authorizing new services that require tariff or chargeable feature changes for users. 6.2 Flexibility This has a number of implications for management: Customers will increasingly require services to be delivered in shorter time-frames and for shorter lifetimes. Cu
41、stomers require access to new services and need to be able control rapid service evolution themselves. Customers will be using multiple access devices that will not always be purchased from a single supplier. The services that the customer uses will need to be seamless, requiring open and published
42、standards, to ensure service interoperability. The customer will require a variable bandwidth to deliver the services that they require at any given point in time. The customer requires access to their services any time, any place, through any chosen access mechanism. The implication is that Service
43、 Provider processes need to consider flexibility as part of their design, not simply efficiency and cost factors. 6.3 Self service and straightforward services Customers want 24 7 access to support services. Increasingly many of the routine changes to customer services and other inquiries can be sup
44、ported by electronic access through self service portals. To make these portals easy to use it is critical that the ways in which services are designed, and the options presented to the customer are tailored to the customers perception of a service. To allow customer to aggregate services, possibly
45、from many suppliers, requires a conceptually simple and straight forward conceptual model of services to be created and presented to a customer; and for problems to be reported in the context of those straightforward models. A particularly important need for customer satisfaction is that the billing
46、 models presented to customers for NGN Services need to be straightforward and easily related to events and configuration changes that the customer can understand, or has access to, and that form part of the simple service description. 6.4 Security Customers will not entrust their personal informati
47、on, including that held in User Profiles, without operators providing measures to secure this information. The customer requires the service to be secure and reliable both in their home environment and in remote environment operated by other providers. NGN Services may be presented over many access
48、methods including inherently insecure radio paths. Security will depend on Identity Management using cryptographic, and possibly biometric, authentication methods that can be supported over multiple operator domains. National and Regional security regulations will also need to be taken into account.
49、 Adequate security between Service Providers (SP) will also be required. NGN Management will manage the underlying NGN, therefore, the security of the management network is essential to maintaining the security of the NGN. Furthermore, the NGN may incorporate security features that need to be managed by the management network. ITU-T Recommendation M.3400 8 enumerates those security management functions.
