Abstract

Some aspects of the development of mobile communication systems are considered, taking into account perspective technologies and recommendations of ITU. The basic principles of construction of networks of mobile telecommunication are given taking into account potential possibilities of introduction of any scenario of realization of virtual technical functions with the set requirements to the given quality of service. The advantages and disadvantages of separate scenarios for the implementation of the concept of virtual technical functions are considered. The main problem of the project is the complexity of the organization, monitoring and management of the subscriber database. This is due to the fact that the mobile station (MS) has to move freely, changing the service areas of both base station and mobile switching centre (MSC) at any location of the user by the service provided.
The implementing the concept of virtual technical function it is expedient to organize a centralized subscriber database for a particular network that participates in the process of involving the corresponding virtual technical function. When moving a mobile station from the service area of one MSC to the service area of another MSC, they will receive on request the necessary information from the centralized subscriber database. The above fundamental paradigms concerning the technical characteristics of the implemented projects for the construction of networks of mobile telecommunications lead to the conclusion that the potential introduction of any scenario for the implementation of virtual technical functions with the specified quality requirements in the scenario of the SAE/EPS (System Architecture Evolution / Evolved Packet System) project networks.

Keywords: mobile communication, virtual technical function, VTF concept, IMT 2000 project, SAE/EPS project, service quality, intellectual network.
