Abstract :
This paper presents several interesting technologies that will support the next-generation of mobile wireless communications. First, a higher data transmission system based on the Personal Handy-Phone System (PHS) is introduced which provides 64 and 128 kb/s data services. Multi-slot channel assignment, which decreases blocking probability, is also presented. New wireless access, called PHS-ODS, is proposed. This can adaptively determine whether a received signal is voice or data, and forward the signal to the user´s voice or data terminal as appropriate. A wireless agent that combines the conventional mobile agent with information specific to the mobile terminal environment is discussed. Furthermore, the application of AO/DI (always on dynamic ISDN) to wireless system is discussed; its concept and simulated effective data transmission speed are described
