Abstract

PURPOSE: A method for terminating an origination call in a mobile communication system is provided to forward a terminated call to another termination number selected by a termination subscriber or a voice mail box in case that the termination subscriber confirms a calling number and does not want to receive the termination of the calling number when the call is terminated in a termination MS(Mobile Station) having a CNIP(Calling Name Identification Presentation) function. CONSTITUTION: An origination subscriber requests an originating MSC(Mobile Switching Center)(200) to set a call to the second MS(400)(S101). The originating MSC(200) receives the request of the call setup, and sets the call to the first terminating MSC(300)(S102). If an origination call is terminated from the first terminating MSC(300) to the second MS(400)(S103), the second MS(400) rings a bell and displays an origination number of the origination subscriber. If a termination subscriber confirms the origination number, and does not want to terminate the origination number or forward the origination call to another telephone number, the termination subscriber inputs a desired telephone number, pushes a flash key, and requests the first terminating MSC(300) to forward the origination call to the pushed telephone number(S104). The first terminating MSC(300) receives the request, transmits the termination number inputted by the termination subscriber to the originating MSC(200), and requests the originating MSC(200) to forward the origination call to the termination number(S105). The originating MSC(200) receives the request, transmits the termination number to an HLR(Home Location Register)(500), and requests information about the termination number(S106). The HLR(500) receives the request, and transmits information about the termination number to the originating MSC(200)(S107). The originating MSC(200) receives information, and sets the origination call to the second terminating MSC(600)(S108).

Description

Method for incoming call origination in mobile communication system {Method for incoming of originating call in mobile communication system}

The present invention relates to a method of receiving an incoming call in a mobile communication system that allows a subscriber to selectively receive a call by checking the calling number when a call is received by the mobile subscriber. In particular, the caller ID (CNIP) function is provided. When a call arrives at a mobile phone subscriber having a call, the called party confirms the caller ID and, if the caller does not want to call the caller, transfers the call to another caller ID or voice mailbox selected by the subscriber. Register the additional service function that can transfer the call to the number selected by the called subscriber in the registrar (HLR), and when the subscriber rings the called number and press the Flash Key, This allows the call to be diverted so that the subscriber can revert to the call when the call is difficult. In a mobile communication system ever provide convenience to those related to the called method outgoing call.

In general, an originating MSC sends a routing request signal to a terminating MSC to which a called party attempted to make an originating call is connected when there is an originating attempt from a connected subscriber. The terminating exchange then sends a busy signal to the originating exchange in response to the routing request when the terminating subscriber is busy with another subscriber.

When the above configuration is described in more detail, if there is an outgoing attempt, the subscriber router is requested, and it is determined whether the called subscriber is busy. If it is determined that the subscriber is in a call, it fails as a result of the router request return and notifies the calling subscriber. On the other hand, if it is determined that the subscriber is not busy, the relay line is successfully occupied and the next procedure of call processing is performed.

In the mobile communication system as described above, the call forwarding function when the subscriber does not answer the call rings at the mobile terminal of the called subscriber. The function of switching to another number or voice mailbox, and the caller ID display (CNIP) function is a function that allows the function holder to check the caller ID by displaying the caller ID that is received as a function holder.

By using the above two functions, the function holder checks the caller's caller's call number when the call is ringing. If the caller does not answer the call, the caller can call the registered phone number or voice mail box. You can forward the call.
