Abstract

A global subscriber group service system capable of accommodating individual subscribers as a terminal within a global subscriber group. The system also permits the subscriber to access a service control node for new registration or modification of the types of services. The system, therefore, includes a customer access function in a local switching node that is controlled by the service control node. The customer access permits the subscriber to access the service control node to make a necessary registration or a change of the type of services.
