The soft-switch is an important entity in NGN. How to flexibly provide abundant applications and adapt new protocols presents an essential problem. This paper proposes a new enhanced multiparty call model for soft-switch. Firstly, the reasons why IN call model or H.323 call model are not suitable for soft-switch are analyzed. Secondly, a soft-switch call model is addressed. Finally, a simple multiparty service is illustrated using this call model.
