Multimedia telephony is a delay-sensitive application. Packet losses, relatively less critical than delay, are allowed up to a certain threshold. They represent the QoS constraints that have to be respected to guarantee the operation of the telephony service and user satisfaction. In this work we introduce a new smartphone architecture characterized by two process levels called application processor (AP) and mobile termination (MT), respectively. Here, they communicate through a serial channel. Moreover, we focus our attention on two very important UMTS services: voice and video telephony. Through a simulation study the impact of voice and video telephony is evaluated on the structure considered using the protocols known at this moment to realize voice and video telephony
