✦ Synopsis

Standardization activities for developing functional and network architecture(s) for third generation mobile communication systems are underway within ETSI and ITU. Intelligent network (IN) features are part of a trend for the development of the universal mobile telecommunication system (UMTS) and future public land mobile telecommunication system (FPLMTS) in ETSI and ITU respectively. Many system functions, such as handover, could be potentially implemented as IN services. In this paper we elaborate on the design of IN-based UMTS handover-related functional and network entities (FEs/NEs), and formal modelling of the integrated IN/UMTS handover service provision model using SDL mechanisms. The mapping of UMTS FEs and NEs to IN and SDL concepts is also introduced and described. The modelling presented here considers the set of IN concepts imposing a frame addressed to IN service objects development and, transition aspects between IN model planes. It also serves as an evolutionary system design for the rapid introduction of UMTS services in a servicefeature based IN/UMTS environment. This also provides for the design of a generic, impervious to development errors which crop up and unambiguous handover control protocols.
