Abstract: The deficiency of nowadays Intelligent Network (IN) on the support of the personal communication is analyzed in this paper. The conceptions of the customized service and the personai service are defined in connection with the requirement of the personai communication. With the CORBA, mobile agent and smart card technologies, a prototype of personal communication system based on the distributed IN architecture is proposed and implemented. A three-phase scheme is also given for the IN' s smooth evolution towards the distributed archi- tecture.
