Adopting the Horizontal Layering in the GSM/UMTS Network

Coupled with the growing interest in the third generation mobile communication systems as a standard for the future mobile communications, the need for a set of functions to effectively support advanced telecommunication services in such an environment is also increasing. The separation of the network functionality into independent layers is a key principle in modern networking in the tele- and datacom industry today. The layered thinking is also a very fundamental and visible aspect in a number of standardization initiatives and industry forums, such as the Multiservices Switching Forum, led by several of the largest operators and manufacturers. The paper presents a short overview of horizontal network model as well as the migration steps towards the new network architecture. Finally, it will propose specific migration strategies fo different kinds of operators.
