Abstract

In an exchange system which performs a communication based on personal identification information for identifying respective subscribers, the invention has an object of providing a system which can flexibly accommodate a change of the communication terminal of actual use by a movement, for instance, of a calling-side subscriber or a call-receiving-side subscriber. A camp-on communication managing apparatus of the invention has a personal position registration table in which terminal identification information for identifying a communication terminal registered to a subscriber for each personal identification information for identifying the subscriber is registered, and manages communication terminals used by respective subscribers. Thus, a camp-on communication can be established even where a camp-on-registered subscriber changes his communication terminal of actual use.
