Fixed mobile convergence

Defining "seamless services"

When used in relation to fixed-mobile convergence the term "seamless service" usually refers to "seamless handover", which means that a call in progress can move from the mobile (or cellular) network to the fixed network on the same phone without interruption. This is described by the carrier organisation Fixed Mobile Convergence Alliance (FMCA) in relation to consumer services: "Seamless is defined as there being no perceptible break in voice or data transmission due to handover (from the calling party or the called party's perspective)".
