In related to mobile communication environment, many researchers have studied problems concerning current locations of mobile users and exposure of their movements in the privacy aspect so far Among them, Kesdogan and Pfitzmann[1,2] proposed effective solutions using temporary pseudonym identification, called TP(Temporary Pseudonym) to solve them Unfortunately, they did not propose the mobile originated protocol, but the only mobile terminated protocol In this paper, we propose new mobile originated protocol that expanded the our previous basic proposal[3] for roaming service to the remote domain in mobile communication environments
