BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for short message delivery to a mobile station in the mobile communication switch, and more particularly, to a method for delivering a short message to a mobile station in paging using a control signal message of a selected channel.

In general, short message service is supported in the GSM of TDMA (Time Division Multiple Access) method, which is widely used in Europe, but is not supported in domestic mobile communication service and CDMA mobile communication system.

Thus, there is a problem in that the conventional CDMA method cannot use the advantages of the short service widely used in the TDMA method.

An object of the present invention for solving the above problems is to perform a paging response for a voice call without performing a separate paging to transmit a simple message (short) to the mobile station being paged, which is a process of searching for a destination terminal to support a voice service. The present invention provides a method for short message delivery to a mobile station, which is a paging loop for connecting a voice call and transmitting a short message.

A feature of the present invention for achieving the above object is a short-term delivery method for receiving an inter-processor communication signal message including a short message and delivering the short message to a mobile station that is paging when the terminal is being paged, the paging from the terminal being paged. The first step of determining to transmit the short message using the traffic channel of the radio section set as a response, includes the short message waiting state in the terminal-related information, and stores the information about the short message applying block requesting the short message transmission A second process of a second process, a third process of waiting for a paging response, a fourth process of receiving a paging response for a called terminal, a fifth process of extracting mobile station signal access block information for controlling traffic matching between the base station configured as a paging response and an exchange period Sends signaling message including process and short message to mobile station signal access block That can then request a short message transmission waiting lies in comprising a sixth process of a short message requires the application unit block.

In the CMS, the short message service is inputted from the SMS terminal and delivered to the short message service center via the base station to the short message service center. The short message is stored in the corresponding terminal by searching for the status and routing information of the called terminal. The process is performed by finding the status and routing information of the mobile communication exchange and the destination terminal managing the area and transmitting the information to the destination terminal via the base station managing the location area.

The short message service of the CMS uses a store and forward function of a short message service-message center (SMS-MC) housed in the CMS, between the mobile station and the mobile station, and a public switched telephone network (hereinafter, referred to as a public switched telephone network). PSTN (abbreviated as PSTN) is a service for transmitting simple text information such as a short length of short text between the mobile station. Using this short message, the CMS (CDMA Mobile System) can provide three services: Cellular Paging Teleservice (CPT), Cellular Message Teleservice (CMT), and Voice Mail Notification (VMN).

CPT is a function to provide a pager function, CMT is a function to send a simple message, and VMN is a function to notify the arrival of a voice mail box in conjunction with a voice mail service.

In order to provide short service, CMS supports communication in several ways.

A control signaling message of an access / paging channel or a traffic channel is used for communication between radio base stations of an SMS terminal (Short Message Service Mobile Station).

An interprocessor communication (IPC) signaling message is used for communication between the base station and the mobile communication switch (MX).

In addition, the MAP (Mobile Application Part) signaling message of the common line signaling method is used for communication between the mobile communication exchange and the short message service center.

When a short message is transferred from the short service center to the mobile switching center to transmit the short message stored in the short service center to the receiving SMS terminal that is paging, the exchange sets the paging response to transmit the short message in the radio section between the base station and the SMS terminal. After determining to use a channel, a method of transmitting a short message using an IPC signaling message between a switch and a base station and a control signal message of a traffic panel in a wireless section of the base station and the receiving SMS terminal is described.
