In order to better meet customer needs, WIDESTAR II system based on the WIDESTAR system for mobile terminals, base station equipment and the development of core network nodes again, thus achieving higher transmission rates as well as other general IMS or IP flexible and compatible technology. In this paper,Will be the first to WIDESTAR II system for brief introduction and analysis, then, To study and validate the system spectrum efficiency method, used by IP compatible technology as well as lower delay strategy such as satellite mobile communication system.
