METHOD AND SYSTEM FOR RECEIVING USING SMSC AND VARIATING SELECTIVELY THE NOTIFYING METHOD FOR THE UNCOMPLETED CALL INFORMATION IN THE MOBILE TELECOMMUNICATION NETWORK}

The present invention relates to a method and system for collecting incomplete call information and notifying subscribers using SMSC in a mobile communication network.

An incomplete call refers to a case in which the caller cannot make a call with the called party (recipient) .In a mobile communication network, the terminal is turned off, out of service area, no answer, busy, call forwarding, rejection, There is a status such as voicemail connection.

Looking at the prior art of a method and system for notifying subscribers of incomplete calls in a mobile communication network, there is a method using a Voice Mail Service (VMS) method and a Visitor Location Register / Home Location Register (VLR / HLR).

The service using the VMS generates information on the incomplete call from the connected VMS and sends it to the SMSC when the called party is set to automatically connect to the VMS when the call comes in or when the call is not answered. To notify subscribers by

In the above service, each SM (Short Message) is generated for the generated incomplete call and the incomplete call information is transmitted to the SMSC. Incomplete call occurs in many cases, such as power OFF of the terminal or out of service area, in which case, the SMSC cannot receive the short message. Therefore, the short message generated to notify the incomplete call information is accumulated in the SMSC instead of the subscriber's terminal, which imposes a heavy load on the SMSC.

Service using VLR / HLR recognizes incomplete call in VLR / HLR involved in call processing and notifies the incomplete call information to separate system through MAP Message and sends short message information to SMSC in the system. This is how you notify. The above scheme is interworked with SS7 / MAP networks and separate incomplete call notification systems in which multiple VLR / HLRs manage incomplete call information. In this case, since many incomplete call notification systems need to be connected to the mobile communication network using SS7, finite resources because it consumes network resource called SS7 signaling link and occupies the PC (Point Code) that is the identifier of the system in SS7 signaling network. This results in reducing PC resources. In addition, VLR / HLR must maintain additional information necessary to select the incomplete call notification system in order to deliver the incomplete call information that occurred, and through this information, VLR / HLR HLR system load is a problem.

In addition, in the case of the service method, the notification means for incomplete call information is limited to the subscriber's mobile terminal, so that the subscriber cannot receive the incomplete call information when the subscriber portable terminal cannot receive the incomplete call information due to loss or lack of power. There is a problem that I cannot receive

An object of the present invention is to provide a method and system for collecting incomplete call information using SMSC to notify the subscriber in a manner selected by the subscriber according to the situation in order to solve the problems of the prior art in the mobile communication network as described above.
