130,131: Short Message Service Center

In general, SMS stands for Short Message Services and is expressed as a short message service.

The short message service defines a point-to-point service that allows ETSI (European Telecommunication Standard Institute) to send and receive characters of up to 155 bytes between incoming / outgoing mobile terminals for application to digital cellular communication systems in Europe. Proposed.

A characteristic of the short message service is that it can be serviced regardless of the operating state of the mobile terminal using an access channel and a paging channel as well as a traffic channel.

In general, as the short message is transmitted from the calling mobile terminal, the short message service center is provided to the short message service center through the calling base station, the calling base station controller, and the calling exchange.

The short message service center requests the home location register (HLR) for location information of the called party receiving the short message of the calling mobile terminal, and the home location register sends the called mobile terminal to the short message service center. Provides location information.

The short message service center transmits the short message provided by the calling party to the called party mobile terminal through the called party exchange according to the location information of the provided called party mobile terminal.

However, when the originating exchange is in operation, the station number change operation frequently occurs, and there is a problem in that user inconvenience due to a work error increases.

That is, as a failure occurs in at least one short message service center of the short message service center executed in association with the exchange, there is a problem that the short message of the calling party is not performed to the corresponding called party.

In order to solve the above problems, the introduction of the gateway short message service center may be considered, but the gateway short message service center to be introduced is expensive equipment, and a problem in which additional cost is additionally generated due to the installation of the equipment. There is this.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is connected to a mobile relay exchange, and at the same time, a short message service center is connected to the mobile relay exchange in a group form to change the station number acceptance of the exchange. It is an object of the present invention to provide a short message relay system and a method for processing an incoming call of a short message through at least one short message service center adjacent to a group when a short message service center fails.

A short message relay system according to an embodiment of the present invention for achieving the above object is connected to at least one source exchange, connected to a grouped short message service center, the short message transmitted from the source exchange And if a failure occurs in any one of the short message service centers to transmit the message, a mobile exchange for performing call processing of the short message to another short message service center in the group.

In addition, the short message relay method according to an embodiment of the present invention for achieving the above object, a) establishing a signal point for the short message delivery, b) the originating mobile terminal based on the established signal point Confirming the corresponding called number as the short message is transmitted from the terminal, and searching for a signaling point of the short message service center, c) determining whether the searched short message service center has a failure, d) searching the short message according to the determination Requesting a call processing of the short message to another adjacent short message service center in the group in the event of a failure, e) sending a short message requesting a call processing at the short message service center.

1 is a short message relay system according to an embodiment of the present invention.

As shown, the short message relay system includes an originating MSC (Mobile Switching Center) 100, 101, CGS (Cellular Gateway Switch) 110, signaling point information DB 111, STP. (Signal Transfer Point) 120, SMSC (Short Message Service Center) 130, 131.

The calling side exchange (100, 101) is configured to send a short message provided from the calling mobile terminal to the short message service center (130) (131).

The mobile relay exchange 120 interoperates with the calling exchange 100 and relays a short message provided from the calling mobile terminal to the short message service centers 130 and 131, wherein the short message service center 130 (C) is configured to perform call processing of the short message to another short message service center 131 adjacent to the short message.

Signal point information DB 111 is configured to store signal point information of the short message service centers 130 and 131 connected to the mobile relay switch 110 and connected to the mobile relay switch 110.

The signal point information includes station-specific information of the short message service centers 130 and 131, and when the short message service center 130 fails to other short message service centers 131 through the signal point information. Allow short messages to be sent.

The signal transmitter 120 is configured to interwork with the mobile relay switch 100 to deliver an outgoing message provided by the originating switch 100 or 101 according to a common line signaling method (No. 7).

The short message service centers 130 and 131 are configured to receive an outgoing message transmitted from the originating exchange 100 and 101 through the mobile relay exchange 120 and provide it to the called party.

The operation description according to the above configuration is as follows.

First, in the calling exchange 100 and 101, the signaling point of the short message service center assigned to each station number is deleted, and as the calling message is transmitted from the calling mobile terminal, the neighboring switch 100, 101 moves adjacent to the calling exchange 100. A short message routing signal point is generated to the relay exchange 110 so that the outgoing message is transmitted through the common line signaling method No. 7.

Meanwhile, multiple mobile relay exchanges 110 adjacent to the source exchange 100 and 101 may be configured through redundancy.

In addition, it is possible to prevent an increase in the load of the signal transmitter 120 by connecting to the common line signaling method (No. 7) between the source exchanger (100) 101 and the mobile relay exchange (110).

In the state in which the originating exchange 100 and 101 and the mobile relay exchange 110 are connected, the mobile relay switch 110 does not generate a signal point of a short message service center for the current station number. Create a signaling point for a short message service center.

The generated signal point information of the short message service center is stored in the signal point information DB 111 interworking with the mobile relay switch 110. In this case, the signal point information DB is illustratively shown in the short message service center of FIG. After grouping (130) (131), the short message service center 130 enables one short message service center 130 within the group to process an outgoing message to another short message service center 131 in the group in case of failure. Grouping related information about the 131 is included.

Then, the mobile relay switch 110 translates the destination number of the short message transmitted from the source switch 100 and 101, and then signals the corresponding short message service center from the interworking signaling point information DB 111. Check the point.

As the mobile relay switch 110 confirms the signal point of the short message service center of the corresponding destination number, the mobile relay switch 110 transmits the outgoing message to the corresponding short message according to the signal point path of the corresponding short message service center. The outgoing message is transmitted to the service centers 130 and 131.

As the outgoing message is provided to the corresponding short message service center 130, 131, the corresponding short message service center 130, 131 receives the response message and goes to the original calling side exchange 100, 101. Send a response message to notify the completion of sending outgoing message.

2 is a flowchart of a short message relay method using a mobile relay switch according to an embodiment of the present invention.

First, a routing signaling point for transmitting an outgoing message from the originating exchange 100 to the mobile relay exchange 110 is generated (S200).

At this time, the load of the signal transmitter 120 interworking with the mobile relay switch 110 is connected by the common line signaling method (No. 7) between the calling switch 100 and the mobile switch 110. Do the sharing.

In addition, the mobile relay exchange 110 is connected to another adjacent mobile relay exchange through the redundancy.

In the state in which the originating exchange 100 and 101 and the mobile relay exchange 110 are connected, a signal point of a short message service center for each station is generated in the mobile relay exchange 110 (S210).

That is, to generate a signaling point of the short message service center corresponding to the destination number of the outgoing message transmitted from the source exchange 100 (101).

In addition, the generated signal point of the short message service center is stored in the signal point information DB 111 linked to the mobile relay 110.

As the outgoing message is transmitted from the calling mobile terminal through the calling exchange 100, 101, the mobile relay switch 110 receives the called number of the outgoing message transmitted from the calling exchange 100, 101. After translation, the signal points of the corresponding short message service centers 130 and 131 are searched for (S220).

The mobile relay switch 110 searches for signal points of the short message service centers 130 and 131 corresponding to the destination number of the outgoing message, and then checks whether the corresponding short message service centers 130 and 131 are faulty. It is determined (S230).

For example, when the mobile relay switch 110 identifies a failure of the short message service center 130 corresponding to the called number of the outgoing message, the short message service center grouped with the short message service center 130 exists. If the corresponding short message service center 131 exists, it requests a call processing for the outgoing message (S240).

The short message service center 131 transmits the corresponding outgoing message to the called side exchange (S250).

Thereafter, the short message service center 131 receives a response signal according to the outgoing message transmission from the called side exchange and transmits a response message to the calling side exchange 100 and 101, thereby transmitting a short message to the calling mobile terminal. Notify you that it is complete.
