Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a GSM mobile communication exchange for originating and processing shortened messages in accordance with the present invention.

Herein, the Mobile Subscriber Interface (hereinafter referred to as MSI) 10 is an A interface matching block, which converts an access request signal and a shortened message from the base station controller 1 into an internal signal form. It is configured to apply to the Short Message Control (hereinafter referred to as SMCO) 20. The MSI 10 is configured to apply to the base station controller 1 an access request permission signal and response and an error message applied from the SMCO 20.

When the access request signal is applied, the SMCO 20 checks with the Location Register Access Control (LRAC) 30 whether the access request signal and the short message service are approved. In addition, when the SMCO 20 is approved for the access request from the LRAC 30, the SMCO 20 applies an access request permission signal to the base station controller through the MSI 10, and if it is approved for the short message service, the short message gateway and Short Message Gateway Interworking Control (hereinafter referred to as SMGIC) 40 is configured to transmit a short message origination signal. In addition, the SMCO 20 is configured to apply a response from the SMGIC 40 and an error message signal to the MSI 10.

Here, the VRAC (Vistor Location Register) which is a database is comprised in the LRAC 30, and all the information about the terminal which exists in the area which a switch manages is stored in the VLR. Accordingly, the LRAC 30 determines the grant of the access request and the short message service based on the information in the VLR and applies it to the SMCO 20.

The SMGIC 40 is a route management block between exchange service centers, and when a short message origination signal is applied from the LRAC 20, the SMGIC 40 checks the route with the service center and applies it to the MAPC (MAP Control) 50. In addition, the SMGIC 40 is configured to apply a response message from the MAPC 50 to the SMCO 40.

The MAPC 50 encodes the short message originating signal in the form of an internal signal and applies it to the service center, and sends a response message indicating whether the short message originating signal is received from the service center (including a terminal idle state and call status). It is configured to apply to the SMGIC 40.

FIG. 2 shows a flowchart in which each component operates over time in the GSM mobile communication switching device having the above-described configuration.

As shown, the base station controller 1 transmits an access request signal to the MSI 10 (step 101). Upon receiving the access request signal, the MSI 10 converts the access request signal into an internal signal form and transmits it to the SMCO 20.

The SMCO 20 confirms to the LRAC 30 whether or not the access request signal is applied (if the access request is granted in step 102), and grants the access request permission signal to the base station controller 10 through the MSI 10. If the access request is not granted (step 103), an error message is generated and applied to the controller 10 to cause the base station controller 1 to terminate the process of sending the shortened message (step 104, 105).

However, when the access request permission signal is applied, the base station controller 10 applies the short message transmission signal including the actual short message content to the SMCO 20 through the MSI 10 (step 106).

The SMCO 20 checks whether the short message service is provided to the corresponding terminal through the LRAC 30 when the short message transmission signal is applied (step 107), and if the short message is provided from the LRAC 30, the SMGIC is approved. Applying this short message origination signal to 40 causes the SMGIC 40 to encode the short message origination signal and apply it to the MAPC 50 (step 108).

However, if the provision of the short message from the LRAC 30 is not allowed, the SMCO 20 forms an error message and sends the error message to the base station controller 1 through the MSI 10 to the base station controller 1. Cause the sending process of the short message to be terminated (steps 109 and 110).

The MAPC 50 applies the short message transmission signal input in the above-described step 108 to the service center, and notifies whether the short message transmission signal is received from the service center (including the terminal idle state and the call status). The response message is received and applied to the base station controller 10 through the SMGIC 40, the SMCO 20, and the MSI 10 again (steps 112 and 113).

The base station controller 10 determines whether the terminal is in the idle state by inputting the response message. If the terminal is in the idle state, the base station controller 10 terminates all processes after performing the call release procedure (steps 114 and 115).

As described above, the present invention has an effect that the short message from the base station controller of the GSM mobile communication system can be easily processed.
