ABSTRACT:
According to a call waiting indicating method and system, a selection number consisting of a terminating subscriber number and a predetermined special number dialed by an originating subscriber and requesting an originating subscriber-initiating call waiting service is received. The received selection number is analyzed to determine whether a terminating subscriber corresponding to the terminating subscriber number rejects the originating subscriber-initiated call waiting service. A connection request is notified to a busy terminating subscriber speaking to a partner subscriber when it is determined that the terminating subscriber does not reject the originating subscriber-initiated call waiting service. A response representing approval signal is received from the busy terminating subscriber in response to notification of the connection request. The partner subscriber is temporarily held upon detection of the approval signal from the terminating subscriber, and a network is driven to connect the terminating subscriber to the originating subscriber.
