Fixed mobile convergence application services using ID mapping database on IMS (IP multimedia subsystem)

This paper proposes a new concept of a fixed mobile convergence (FMC) application architecture by using an ID mapping database for accommodating many kinds of devices on different fixed and mobile network. We propose two approaches to create new FMC services. One is linked multiple call sessions over multiple terminals and the other approach is to focus on a customer ownership of multiple terminals. We also describe a method of implementing linked network services to be used for PCs on a fixed network and for mobile phones on a mobile network, by using a common application accessed by each network and an ID mapping database. Lastly, we describe an implementation approach by using a prototype system.
