Abstract

PURPOSE: A call waiting service method based on subscriber appointment in a mobile communication network is provided to consult the convenience of mobile subscribers by making a call waiting service applied only for appointed mobile terminals. CONSTITUTION: If the second calling mobile terminal(14) attempts call origination to a called mobile terminal(10) in the middle of the voice call between the called mobile terminal(10) and the first calling mobile terminal(12), a call waiting service server(18) judges whether the second calling mobile terminal(14) is a terminal appointed by the called mobile terminal(10) for a call waiting service. In case that it is judged that the second calling mobile terminal(14) is an appointed terminal for the call waiting service, the call waiting service server(18) sends a call waiting tone signal to the called mobile terminal through a mobile communication network. If the called mobile terminal(10) makes a response for a voice call with the second calling mobile terminal(14), an associated MSC transfers the first calling mobile terminal to a waiting state.

Description

CALL WAITING SERVICE METHOD BY DESIGNATION OF SUBSCRIBER IN MOBILE COMMUNICATION NETWORK}

The present invention relates to a call waiting service method according to a subscriber designation in a mobile communication network. More particularly, the present invention relates to a call waiting service of a mobile communication network. The present invention relates to a call waiting service according to a subscriber designation.

In general, a mobile communication network system is configured to perform a voice call or data communication with a counterpart while moving to an arbitrary area according to a user's needs of a mobile communication terminal, which manages a current communication area of each mobile communication terminal. Call connection and call connection status by confirming the location of each mobile communication terminal by mutual information communication between the mobile communication switch and the home location register which stores and manages the information of the terminal subscribers and the location information of the terminal. Handoff at is enabled.

On the other hand, recently, when a mobile communication terminal subscriber or a wired telephone terminal subscriber requests a call setup for a specific mobile communication terminal in a mobile communication network system, the phone number of the calling party's terminal is displayed on the called mobile communication terminal. Since the caller ID display service is executed, the caller ID display service enables the caller to identify the caller in advance, while being able to arbitrarily select a counterpart.

Further, in such a mobile communication network system, when there is a call from another caller while a called party is in a voice call with a predetermined caller, the caller is called from another caller using the caller ID display service. By displaying the call waiting service, a call waiting service is applied, which enables a caller who is in progress of a voice call to go to a standby state and proceeds with a voice call by a call connection with another caller.

However, in such a conventional mobile communication network system, when a subscriber of a called mobile communication terminal is in a voice call with a predetermined caller and there is a call origination from another caller, the caller is in a standby state with the caller who has performed the voice call. You can switch and conduct a voice call with another caller, but if you have a call waiting tone signal from another caller who is relatively insignificant during a voice call with a certain caller, break the important call flow. There is a problem that there is a fear that it may interfere with the call.

Accordingly, the present invention has been made in view of the above-described conventional circumstances, and an object thereof is a method of waiting for a call according to a subscriber designation in a mobile communication network, which enables only a call waiting service for a caller designated by a subscriber of a mobile communication network. To provide.

It is another object of the present invention to induce an additional message notification service for an originating mobile communication terminal which is not designated as a terminal of a waiting service by a subscriber of a mobile communication network so as to inform a subscriber of a call origination status. To provide a standby waiting service method according to the subscriber designation in.
