Description

SYSTEM FOR MAKING FEE INFORMATION OF SHORT MESSAGE, MESSAGE DELIVERY SERVER AND METHOD THEREOF}

The present invention relates to a short message charging information generating system, a message transmission server, and a short message charging information generating method. In detail, the present invention relates to a short message transmitted from an originating terminal regardless of a character code set of an originating and receiving terminal. A short message charging information generating system for generating billing information, a message transmission subscribing method, and a method for generating short message charging information.

If the character code set used by the calling terminal and the called terminal is different, the short message center converts the short message transmitted from the calling terminal into a character code set that the called terminal can process and transmit.

For example, suppose that the calling terminal is a terminal manufactured in Korea and the called terminal is a terminal manufactured in Europe. The calling terminal uses the domestic standard KSC5601 character code, and the called terminal uses the European standard UCS2 character code. Will be used.

Since the KSC5601 character code and the UCS2 character code are not compatible with each other, the short message center converts the short message of the calling terminal composed of the KSC5601 character code into a UCS2 character code that can be processed by the called terminal.

The conversion of the character code performed in the short message center enables smooth short message transmission and reception between terminals using different character code sets. However, in this case, there is a problem that the length of the message body may vary during the conversion of the character code.

The present invention provides a short message charging information generation system, a message transmission server, and a short message charging information generating method for generating charging information according to a length of a short message transmitted from an originating terminal regardless of a character code set of an originating and receiving terminal. will be.

In order to achieve the above object, the short message charging information generation system according to the present invention generates a short message and calculates the length of the short message transmitted from the terminal, embeds the short message as an original length parameter, And a message transmission server that maintains the parameter as it is and relays billing information according to the parameter when the original length parameter is embedded in the short message.

In this case, when the relayed short message is a combined short message composed of a plurality of short messages, the message transmission server may generate charging information according to an original length parameter included in the last short message constituting the combined short text.

Meanwhile, the message transmission server according to the present invention calculates the length of a first Short Message Service (SMS) message transmitted from a terminal and embeds it in the first SMS message as an original length parameter, and the original length parameter is embedded. Receiving the first SMS message and converting it into a second SMS message that can be received by the called terminal, but retaining the original length parameter, and the second SMS message when the second SMS message is received by the called terminal. The billing information generator may be configured to generate billing information according to the original length parameter included in the SMS message.

In this case, the second SMS message may be converted from a text code set of the first SMS message to a text code set that can be processed by the called terminal.

In addition, the original length parameter may be embedded in the first SMS message and transmitted from another message transmission server.

The charging information generator may generate charging information according to an original length parameter included in the last short message constituting the combined short message when the second SMS message is a combined short message.

The parameter generator may embed the original length parameter in a PDU body region in a short message structure according to a Short Message Peer to Peer (SMPP) standard.

In addition, when the first SMS message is a concatenated message, the length of the short message may be the sum of the lengths of the segments of the concatenated messages transmitted from the terminal.

On the other hand, the short message charging information generating method according to the present invention comprises the steps of receiving a first SMS message from the terminal, calculating the length of the first SMS message and embedding in the first SMS message as the original length parameter, the original Receiving a first SMS message with a length parameter embedded therein, converting the second SMS message into a second SMS message that can be received by the called terminal while maintaining the original length parameter, and transmitting the second SMS message to the called terminal; 2, if the SMS message is transmitted to the called terminal, generating charging information according to the original length parameter included in the second SMS message.

In this case, the second SMS message converting step may include the original length parameter in at least the last short sentence constituting the combined short sentence when the second SMS message is a combined short sentence composed of a plurality of short sentences. Here, the charging information generating step may generate charging information according to the original length parameter included in the last short sentence.

As described above, the short message charging information generating system, the message transmission server, and the short message charging information generating method according to the present invention embed the original length parameter which is not changed in the transmission process in the short message transmitted from the calling terminal. By generating the charging information using this, charging is charged according to the length of the short message created at the calling terminal.

Therefore, the user of the originating terminal that is actually subject to billing can pay the expected billing when using the short message regardless of the character code set of the called terminal.

As a result, the motivation for the use of the short message by the calling terminal user can be improved.

Hereinafter, a short message charging information generating system, a message transmission server, and a short message charging information generating method according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a short message charging information generation system related to the present invention.

The short message charging information generation system shown in FIG. 1 generates the short message and calculates the length of the short message transmitted from the terminal, embeds the short message as an original length parameter, and embeds the short message in the short message. When the short message is relayed, the original length parameter is maintained as it is, and includes a message transmission server 130 for generating charging information according to the original length parameter.

The terminal 110 may generate a short message and is a terminal subscribed to the short message service provided by the message transmission server. In general, a terminal capable of generating a short message has a function of receiving a short message generated by another terminal through the message transmission server and displaying the short message. That is, the terminal may function as a called terminal.

The terminal 110 generates a short message and transmits the short message to the message transmission server through a communication network using the base station 120. At this time, the user of the terminal can recognize the fee of the short message generated by the user. In general, since billing for short messages is divided into the number of short messages, a short message within a certain length is charged for one message, and two or more charges are charged for the length of a short message over a certain length. do. Therefore, the terminal user generally generates a short message by adjusting the length within one possible charge range.

The message transmission server 130 receives the short message generated by the terminal through a communication network and transmits the short message to a destination terminal targeted by the short message or to another message transmission server that can be transmitted to the destination terminal.

When the short message transmitted from the terminal cannot be processed by the called terminal, the message transmission server converts the short message to be processed by the called terminal. However, in this conversion process, the length of the short message may be changed.

For example, when the body ⓐ of the short message generated and transmitted by the terminal is 'a width of 4m and a depth of 2m in the channel, the mind is R = A / P = 2 * 4/2 + 4 + 4 = 1'. If the character code set used in the terminal is KSC5601, the short message is 70 bytes in length. If billing is done in 80-byte units, the terminal user expects to be charged for one short message because 70 bytes are within 80-byte units.

2 shows a time point for charging the terminal when the short message is transmitted from the terminal.

When the terminal A generates a short message and requests the call to the called terminal, the message transmission server attempts to receive the called terminal B until the receiving terminal B normally receives the short message. As a result of the incoming attempt, the receiving terminal B normally receives the short message is the charging time for the terminal A. The charging charge is not based on the length of the short message transmitted from the terminal A, but based on the length of the short message received from the called terminal B.

However, as in the present case, in a system in which charging is performed according to a length of a short message received by a called terminal in a state in which a short message is normally received in a called terminal, a situation in which charging is further added may occur.

In the above example, when the called terminal uses the KSC5601 character code set similarly to the terminal, the message transmission server transmitting the short message to the called terminal transmits the text ⓐ without conversion of the character code set as shown in FIG. 4. When the short message is normally transmitted from the called terminal, the message transmission server confirming the short message generates charging information according to the length of the short message transmitted to the called terminal. In this case, since the length of the short message that is the basis of the generated charging information is the same as the length of the short message generated by the terminal, the charging information is generated as the terminal user expects.

However, when the destination terminal uses the UCS2 character code set, the message transmission server converts the short message written in the KSC5601 character code set to the UCS2 character code set as shown in FIG. 5 so that it can be used in the destination terminal. In this process, the body ⓐ of the original 70 bytes becomes 104 bytes. This is due to the difference between the fundamental character code set of KSC5601, which handles English as one byte, and UCS2, which handles English as two bytes. Therefore, when the short message is normally received by the called terminal, the message transmission server confirming this generates billing information for 104 bytes, which is the length of the short message transmitted to the called terminal. In other words, since it exceeds 80 bytes, two short messages are charged.

As a result, the terminal user who has sent one short message has no choice but to complain about the two short messages.

This phenomenon occurs even in the case of call forwarding. In the case of call forwarding, as shown in FIG. 3, charging information for the calling terminal is generated according to the length and the number of short messages received by the called terminal at the time when the called terminal is called.

As shown in FIG. 6, the terminal A may generate and transmit a short message using the KSC5601 character code set, and receive the message from the terminal B and transfer the call to the terminal C. If the terminal B uses the UCS2 character code set and the terminal C uses the KSC5601 character code set, the message transmission server converts the short message to KSC5601-UCS2-KSC5601 while attempting an incoming call.

The short message generated by the terminal A is 80 bytes, and is converted to UCS2 for processing in the terminal B to be 120 bytes. The 120 bytes are divided into two cases for 80-byte charging units (transmissions are also made in 80-byte units). After that, the terminal B converts the call to KSC5601 for processing in the terminal C. The short message received by the terminal C becomes 80 bytes in this process, but two short messages of 80 bytes and 40 bytes are transmitted from the terminal B. Therefore, the short message is divided into two 60 bytes and 20 bytes. Therefore, even though the terminal C has received an 80-byte short message, two pieces of charging information are generated and charged to the terminal A. On the other hand, in the case of call forwarding, the terminal C may be charged. Even in this case, the user of the terminal C has a complaint because the user is charged for two short messages even though the user receives one short message. .

The message transmission server 130 of the short message charging information generation system shown in FIG. 1 calculates the length of the short message transmitted from the terminal, embeds the short message as an original length parameter, and relays the embedded short message. The original length parameter is kept as it is, and charging information is generated according to the original length parameter.

According to this, the message transmission server does not change the original length parameter even if the character code set of the short message having the original length parameter is converted during the relay process.

In addition, when the charging terminal generates the charging information after the incoming call, the charging information is generated according to the original length parameter which is not changed in the conversion process. The charging information generated as described above may be charged as expected by the user of the calling terminal by referring to the length ⓑ of the short message generated and transmitted by the calling terminal as shown in FIG. 7. That is, even if the relayed short message is in a state in which the character code set is converted (ⓒ), charging is based on the length ⓑ of the short message generated under a certain character code set used by the calling terminal.

Meanwhile, relaying means receiving a short message from a terminal or another message transmission server and transmitting the short message to a destination terminal or another message transmission server, which may include a conversion of a character code set. The relayed short message may be a short message received with an original length parameter and transmitted through the message transmission server, and may have its character code set converted.

If the relayed short message is a combined short message consisting of a plurality of short messages, the message transmission server may generate charging information according to the original length parameter of the last short message constituting the combined short text. In the case where the relayed short message is a plurality of short messages, a short message may be generated and transmitted from the calling terminal to the plurality of short messages, and a single short message may be divided into a plurality of short messages according to the conversion of the character code set during the relay process. .

In any case, charging for the short message is performed when the called terminal normally receives the last short message. This is because the last short message is normally received, which means that the entire short message is normally received.

Therefore, when the relayed short message is a combined short message consisting of a plurality of short sentences, it is preferable to extract the original length parameter included in at least the last short sentence constituting the combined short text and generate charging information using the same. This is because if the original length parameter included in the short sentence is used to generate billing information, billing may be charged even if the incoming call is not made normally.

Of course, this requires that the original length parameter be embedded in at least the last sentence that constitutes the combined sentence. For short sentences other than the last one, the original length parameter may or may not be embedded.

The message transmission server described above may be a Short Message Service Center (SMSC).

Hereinafter, the message transmission server will be described in more detail.

8 is a block diagram illustrating a message transmission server according to the present invention.

The message transmission server 130 shown in FIG. 8 calculates the length of the first SMS message transmitted from the terminal and embeds it in the first SMS message as an original length parameter, and the original length parameter is embedded. Receiving the first SMS message and converting it into a second SMS message that can be received by the called terminal, but keeping the original length parameter as it is; and receiving the second SMS message by the short message converting unit 133 and the called terminal. In one case, the charging information generator 135 generates charging information according to the original length parameter included in the second SMS message.

The parameter generator 131 calculates the length of the first SMS message transmitted from the terminal (sending terminal), derives a length value, and embeds the length value in the first SMS message as an original length parameter.

If the message transmission server is an SMSC, it is possible to apply the short message peer to peer (SMPP), an international standard used by the SMSC, but it is not limited to the SMPP standard.

According to the SMPP, a short message (SMS message) may be defined in the format shown in Table 1 below.

SMPP PDU PDU Header (mandatory) PDU Body (Optional) command length command id command status sequence number PDU Body 4 octets Length = (Command Length value-4) octets

In Table 1, the body of the short message is located in the PDU Body. When the short message is transmitted, the fields shown in Table 2 are included in the PDU Body area.

S sm_length One Integer Length in octets of the short_message user data. short_message Var. 0-254
Octet String Up to 254 octets of short message user data.
The exact physical limit for short_message size may vary according to the underlying network.

Applications which need to send messages longer than 254 octets should use the message_payload parameter.
In this case the sm_length field should be set to zero.

Note:
The short message data should be inserted in either the short_message or message_payload fields.
Both fields must not be used simultaneously.

sm_length corresponds to the length of the short message, and short_message corresponds to the content of the short message. If the incoming message is successfully received, the billing information is generated.

Looking at it, there is sm_length indicating the length of the short message, but it is not useful. This is because the sm_length is not only converted in the process of converting the short_message according to the character code set, but also when the message is divided into plural numbers as in the case of the call forwarding, the problem cannot be solved. Specifically, sm_length is changed to the length of a short message of the result of character code set conversion, and when divided into a plurality, the sm_length is changed to indicate only the length of the short message included in each case.

Therefore, it is necessary to add an original length parameter which is not changed in the character code set conversion process separately from sm_length.

The original length parameter is generated in the parameter generator and embedded in the short message. For example, the original length parameter may be set to original_message_total_length as shown in Table 3 below.

original_message_total_length TLV The total length in bytes of messages sent from the calling terminal.
In the case of a general short message, it is equal to the length of the outgoing message, and in the case of a concatenated message, the length of each segment transmitted from the terminal is the sum.
This field remains unchanged even by conversion by DCS (Data Coding Scheme).
This field is used as settlement data for outgoing base billing.

The original_message_total_length may be embedded in the PDU body area by extending the short message structure according to the SMPP standard. Specifically, it may be added to the field of Table 2.

Meanwhile, when the short message transmitted from the terminal is a concatenated message, the length of the short message is the sum of the lengths of the segments of the concatenated messages transmitted from the terminal.

The short message converting unit 133 receives the first SMS message with the original length parameter embedded therein and converts it into a second SMS message that can be received by the called terminal. In addition, the original length parameter is maintained as it is during the conversion process.

In the present specification, the second SMS message refers to a text code set of the first SMS message in which the original length parameter is embedded, into a text code set that can be processed by the called terminal. That is, the second SMS message is for distinguishing from the first SMS message which has not undergone the conversion process according to the text code set.

Therefore, the length of the second SMS message may be different from the length of the first SMS message transmitted from the terminal. However, even in this case, the short message converter does not change the original length parameter embedded in the first SMS message during the conversion process. Thus, the second SMS message will have the same original length parameter as the first SMS message with the original length parameter embedded.

In this case, the first SMS short message may include an original length parameter embedded therein and may be transmitted from another message transmission server. That is, the first SMS message may include both the case where the original length parameter is transmitted by the parameter generator and the case where the original length parameter is embedded and transmitted by another message transmission server.

The charging information generation unit 135 generates charging information according to the original length parameter included in the second SMS message when the receiving terminal normally receives the second SMS message. The case where all the second SMS messages are received by the called terminal is normally received. The called terminal transmits a signal indicating that the second SMS message has been normally transmitted to the message transmission server. Through this, the called terminal can check whether the called terminal has been received.

If the incoming terminal is normally received, the billing information generation unit generates billing information. The charging information at this time is generated according to the original length data included in the second SMS message.

Since the original length data is the result of calculating the length of the short message transmitted from the originating terminal, the original length data is the same as the originating reference charging. Accordingly, since the billing is charged in the same way as the rate expected by the user of the calling terminal, it is possible to substantially satisfy the expectations of the caller who is the billing target of the short message.

In this case, when the second SMS message is a combined short message consisting of a plurality of short messages, it is preferable to generate the charging information according to the original length parameter of the last short text constituting the combined short text.

The generated billing information is transmitted to the billing server for processing, and the detailed description of the billing server is omitted since the processing in the billing server is the same as before.

9 is a flowchart illustrating a method of generating short message charging information according to the present invention, which may be expressed as an operation description of a message transmission server.

The message transmission server receives the first SMS message generated by the terminal (S510). In this case, the first SMS message may be transmitted through the base station and a predetermined communication network.

The message transmission server calculates the length of the transmitted first SMS message and generates the original length parameter using the result. Thereafter, the original length parameter is embedded in the first SMS message (S520).

In step S530, the first SMS message having the original length parameter embedded therein is received and the original length parameter is maintained as it is and converted into a second SMS message that can be received by the called terminal. When the message transmission server is an SMSC, it includes an element for receiving a short message from the terminal or another SMSC and an element for transmitting the received short message to the called terminal. The delivery of the short message may occur in real time, but generally takes a certain time in consideration of the circumstances of the called terminal. Therefore, both the element for receiving the short message and the element for transmitting the short message to the called terminal, in addition to the elements for converting the text message to be processed by the called terminal, are separately formed. Therefore, it is said that the first SMS message is delivered above, which means delivery of the first SMS message occurring inside the SMSC. Of course, it also includes delivery of the first SMS message sent from another SMSC.

When the second SMS message is a combined short message consisting of a plurality of short messages, the original length parameter may be included in at least the last short text constituting the combined short text. Short sentences in other positions may or may not include the original length parameter. Since the last short indicates normal incoming, the last short must contain the original length parameter.

The message transmission server transmits the second SMS message to the called terminal (S540). This transmission attempt is repeated until the called terminal normally receives (S550).

When the second SMS message is normally transmitted to the called terminal, billing information is generated according to the original length parameter included in the second SMS message (S560). In this case, when the second SMS message is a combined short message consisting of a plurality of short messages, charging information is generated according to an original length parameter of the last short text constituting the combined short text.

On the other hand, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive.
