Description

Short message service method and apparatus {SHORT MESSAGE SERVICE SYSTEM AND APPARATUS THEREOF}

The present invention relates to a method and apparatus for transmitting a short message, and more particularly, to a method and apparatus for transmitting a short message for quickly transmitting a plurality of short messages for a short time.

Among the mobile communication services, personal communication service (PCS) is a mobile communication service used by an individual, and is a communication service that can perform voice and data communication regardless of time and place using an ultra-compact, ultra-lightweight terminal that is easy to carry.

Wireless mobile communication service subscribers can move freely and communicate anywhere, and are further provided with a function to receive information necessary for life by text.

For example, wireless mobile communication service providers can send news information, weather information, sports information, stock information, exchange rate information, traffic information, etc. to subscribers of wireless mobile communication service by using short message service (SMS) that enables simple message transmission. Providing.

The short message service (SMS) refers to an interactive service capable of sending and receiving short text messages regardless of whether a mobile communication terminal has a call. This service enables subscribers of wireless mobile communication services to send short messages of 105 bytes in Korean or English to other mobile phone subscribers to receive messages over public telephone networks, data communication networks or the Internet.

The short message service according to the prior art will be described with reference to the accompanying drawings.

1 is a schematic configuration diagram of a short message service system according to the prior art.

Referring to FIG. 1, a short message service system according to the related art moves a short message transmitted from an originating terminal 100, a base station 102, an exchange 104, an SMS processing center 106, and an originating terminal 100. And a terminating terminal 108 for receiving via a communication network.

Here, the base station 102 receives a short message (SMS) from the source terminal 100 through an access channel (Access channel) of the signal channel, and transmits the received short message to the exchange 104.

The exchange 104 sends the received short message to the SMS processing center 106 and sends a response message to the base station 102 that the short message transmission is complete.

The base station 102 transmits a response message to the calling terminal 100 informing that the short message transmission is completed through a paging channel of the signal channel.

Here, the paging channel determines the location of the originating terminal 100 included in the base station 102 at a time period of 1 to 3 seconds by an internal timer (not shown), and sends a message to the identified location of the originating terminal 100. Send a response message indicating the completion of the transmission.

At this time, the time period of the paging channel for determining the location of the calling terminal 100 is standardized and operated according to the mobile communication service provider.

The destination terminal 108 receives a short message received via a mobile communication network through a corresponding SMS processing center (not shown), an exchange (not shown), and a base station (not shown).

In general, the signal channel used for short message transmission is unidirectional, and it is specified to proceed with the next step after receiving a response signal for the transmission result.

Therefore, after the short message sender transmits the short message through the calling terminal 100, it is difficult to transmit another short message until the short message is received by the calling terminal 100.

If the short message sender forcibly transmits another short message before receiving a response message indicating completion of the short message transmission to the calling terminal 100, the short message sender complies with the standard protocol of the signal channel between the base station 102 and the calling terminal 100. Therefore, only the first short message sent is correctly transmitted, and the short message forcibly transmitted before receiving the response message is ignored.

The short message transmission apparatus according to the prior art uses a signal channel when transmitting a short message. This method is called a common line signaling method and is currently standardized.

The short message transmission apparatus according to the prior art using a signal channel has an excellent advantage in that a signal channel can be connected to a communication network more quickly than a call channel, and has excellent stability, and thus, transmits one short message.

However, since the short message transmission apparatus according to the prior art uses a unidirectional signal channel, it takes at least 4 to 5 seconds to receive a response message indicating the completion of transmission after one short message transmission.

Therefore, since the short message transmission apparatus according to the prior art takes a lot of time to transmit another short message after transmitting one short message, there is a problem that a large number of short messages cannot be transmitted in a short time.

Accordingly, an object of the present invention is to provide a method and apparatus for transmitting a short message for transmitting a plurality of short messages using a communication channel.

SMS data field 404, which indicates an incoming call number field 406, which indicates the telephone number of the called terminal.

In addition, the short message sender creates a second short message before transmitting a response signal to the first short message to the calling terminal 200 and transmits it to the calling base station 202 through the call channel.

In this manner, the short message sender creates a short message to be transmitted by the calling terminal 200 to the first to N-th destination terminals 214-1, ..., 214-N, through the off-call channel. It sequentially transmits to the originating base station 202.

The originating base station 202 transmits the received first through Nth short messages to the originating exchange 204 via the call channel, and the originating exchange 204 sends the received first through Nth short messages to the originating SMS processing center ( 206).

Here, the time required for receiving the short message from the originating terminal 200 to the originating SMS processing center 206 through the call channel is about 0.1 second.

Subsequently, the originating exchange 204 transmits a response message indicating completion of message transmission for the first to Nth short messages received through the call channel to the originating terminal 200 through the originating base station 202 using the call channel. do.

At this time, the time required for the response message indicating the completion of the message from the originating exchange 204 to the originating terminal 200 is about 0.1 second.

Here, since the call channel is bi-directional communication, even if the second short message is sequentially transmitted after the first short message is transmitted, there is a time difference in transmitting each short message, so that the calling terminal 200 transmits the short message. Together, it may continuously receive a response message from the originating exchange 204.

The originating SMS processing center 206 transmits the continuously received first through Nth short messages to the incoming SMS processing center 208 through the mobile communication network.

The incoming SMS processing center 208 stores the received first through N-th short messages and sends a notification message to the destination exchange 210 that the first through N-th short messages have been received.

The destination exchange 210 notifies the destination base station 212 including the first to Nth destination terminals 214-1,..., 214 -N to the first to Nth short messages. Send a message. Here, the destination exchange 210 transmits a notification message to the destination base station 212 through the signal channel.

Subsequently, the destination base station 212 sends a short message to the first to Nth destination terminals 214-1 to 214-N corresponding to the first to Nth short messages by the notification message informing that the short message is received. Send the received notification message. At this time, the destination base station 212 transmits the short message reception notification message to the first to Nth destination terminals 214-1, ..., 214-N through the signal channel.

The first to Nth called terminals 214-1 to 214-N confirm receipt of the first to Nth short messages through the received notification message, and then the called base station 212 and the called base station through the signal channel. After accessing the exchange 210, the first to Nth short messages stored in the incoming SMS processing center 208 are checked.
