A 4G systems can provide a comprehensive IP based solution where voice, data, video streamed multimedia can be provided to users on an "Anytime, Anywhere". The aim of the paper is to estimate quality of metric values with different IEEE 802.11 standards (IEEE 802.11. b. /a/g), utilized for SIP (Session initialized protocol) video call setup procedure over wireless link scenario directed to mobile devices. The authors used two video call modes of operation over heterogeneous WiFi standards. The proposed model application layers in SIP protocol based on multicast mobile agents used in two different modes of video call established. Initiate services through CBR used for session control overhead packets.
