A personal information storage module(15) stores and deletes the personal data. A subscriber DB(14) stores and manages the personal data of the subscriber. A personal service controller(12), created by the telecommunication processing module, offers the PTAC(50) the optimal data converted according to the features of the network transfer and terminal. A network interface(51) includes a network transfer hierarchy protocol. A profile manager(54) offers the information of the network to the telecommunication processing module in the connection to the PTAS. A data compressor and encryption processor(53) encodes and compresses the personal data for reducing the data quantity and keeping the security. A displayer(52) enables the user to watch the data transferred through the network. A profile editor(55) enables the user to configure directly the optimal data type through a user interface.
