A Service-Oriented Approach to Telecommunications Value Networks

This paper presents a service-oriented model for analyzing and representing telecommunications value networks. Recognizing the complexity and interconnectivity within the telecom sector, it emphasizes the importance of services and the relationships between different components. The proposed model shifts the focus from traditional operations to the value added at each interaction. It includes basic concepts of value networks, service attributes, content, and knowledge exchanges. Ultimately, this approach aims to enhance understanding and integration within the telecommunications industry, accommodating its convergence with information technology and broadcasting.

  2. Introduction • Telecommunication systems are large and complex • Different approaches according to different academic disciplines • Role of services in present telecom business is largely recognized • Convergence between telecommunications, information technology and broadcasting requires new ways to look at the sector • Need of a service modelling approach to telecom sector • Represents the principal system elements and their relationship; • Helps to explain how it works; • Can serve as a basis for related, but more specific, models; • Allows a common ground among several visions.

  3. (Tele)communications models • Engineering models • Shannon • Media and social / mass communications models • Shannon • Osgood-Schramm • Berlo • Economic structural models • Fransman (layers) • Hilbert-Katz (layers / multidimensional) • Value-chain models (Porter and alike) • European Comission Green Paper on Convergence • Kawashima (MIT) • Service chain • Production chain; electronic complex approach

  4. Content production Content processing Collection Transport Storage Distribution or Delivery Consumption Service chain

  5. Proposed reference model • Basic concepts • Networks • interconnected agents, feedback and multiple causality • Value networks • Other way to call a “production network”; emphasis move from operations description to the tangible or intangible value added at each transaction. • Chain representations tend to reproduce the internal “logic” of a firm productive organizations; network representations tend to reflect interactions between firms (apud Sturgeon) • Value networks rely on fragmented rather on vertically integrated forms of industry organization (Berger et al.)

  6. Proposed reference model - II • Basic concepts (cont.) • Service attributes (apud Hauknes) • intangibility or immateriality; • economic exchange properties; • ephemerality or temporary existence of the service; • intensity of user-producer linkages • Exchange between actors (apud Allee) • Goods, services and revenue • Knowledge • Intangible benefits

  7. Proposed model • Proposal • To apply value network concept to telecommunications and “telematics” • To adopt the principle that people uses telecommunications as services and applications • In the proposed model • Content and revenue exchange: service relationships • Knowledge exchange:technological stimuli and demands

  8. Proposed model - I: domains meta-model • Domains of communication process • Content • Interfaces • Transport (network) Content domain Information source and destination Interfaces domain Content formatting and transport codification Transport domain Information flow Information transport

  9. Proposed model - II: roles Roles and content flow in telephony service

  10. Proposed model - III: relationships

  11. A network of non-linear relationships Collect 2 ( access ) Example: internet content retrieval

  12. Collect 2 ( access ) Functional systems Functional systems ICTs Service value network and ICTs Network roles and actors demand functionalities from technological substrate

  13. Conclusion • Reference model developed to represent telecommunications from a service point of view • emphasis on relationships • non sequential roles • focus on communication process, rather than communication goods • ICTs viewed as general substrate providing functionalities and functional systems to service network roles and actors • Understanding of network integration and coordination needs further studies • adequate regulatory framework
