With the rapid progress of research to offer a convenience of mobile communication, the mobile users can use not only the services of voice call but also the variety services of data communication using Internet. These include Internet Searching, Internet Shopping and Internet banking and Internet stock exchange and electronic payment and so on, based on PKI. Also, the need of data communication between the mobile users has been increased. As it is possible for mobile users to do user authentication, key distribution, encryption, decryption and so on, it is needed the certificate status validation between the mobile users. However due to the PCS(Personal Communication System) had been only designed and implemented for voice call between the mobile users, it is not easy to apply data communication between the mobile users on PKI. Therefore the study of for the data communication between the mobile users in PCS is a few. It is for the data transfer between the mobile users to communicate using call processing of PCS. So, we propose how to process the certificate status validation during call processing for data communication between the mobile users in the PCS.
