Agent oriented software technology is a rather new field of software engineering.
Being a simple and convincing metaphor, however, its use both in theory and applications is constantly growing. The field of telematics services lends itself very naturally to the use of intelligent agent, because the model metaphor of distributed and potentially mobile agents, different marketplaces and complex communicating systems is exactly meeting the physical facts in real distributed telecommunication systems. A particularly important aspect in the relationship between telecommunication services and agent oriented systems is that agents communicate in a standard universal language while the subsystem existing in the telecommunication world are highly heterogeneous and complex. Since this is one of the major problems in this field, agent technologies are very promising. That is, the growth of complexity of the functionality provided in the systems is compatible to the growing need to save time and cost at the user side.
