Considerations on network interfaces for third generation mobile telecommunication systems

The paper gives a number of considerations on UMTS interfaces to be standardised. Standardised interfaces are a prerequisite in order to fulfil the UMTS operational requirements. Specific requirements result from the fact that UMTS will be a multi-operator system. The target scenario as adopted by the RACE 2066 MONET Project is to model the UMTS network as an integrated part of networks for fixed telecommunication services. Such a scenario puts additional constraints on the identified interfaces. RACE is an abbreviation of Research and development in Advanced Communication technologies for Europe.
