Message format conversion method and apparatus therefor {Method for Transforming a Message and Apparatus

The present invention relates to a message format conversion method and apparatus thereof.

Short Message Service (SMS) refers to a service that allows a wireless terminal to send and receive text in a short form. Short text is mainly data consisting of letters or numbers. The short message service is a simple email service developed to compensate for the shortcomings of a mobile phone terminal having poor call quality. The sent message is stored in a short message center (SMC) and then transmitted to a user terminal. Although it was started as a data communication application, the range of application is gradually being expanded to provide various information and payment methods of electronic commerce.

In order to solve the shortcomings of the short message service that provides only data consisting of letters or numbers, a multimedia message service (MMS) is provided that can exchange pictures, pictures, videos, etc. from text-based services. . The multimedia message service is developed from a text-based short message service, and can generate and transmit multimedia messages such as pictures, sounds, and videos.

Recently, the Internet Protocol Multimedia Subsystem (IMS) has been attracting attention as a core information communication technology for providing new multimedia services in an Internet Protocol (IP) based next generation communication environment. The internet protocol multimedia subsystem is a set of nodes that provide various multimedia services and perform call control in the environment of a mobile communication network, and integrates the internet protocol network and a mobile communication environment. Accordingly, the internet protocol multimedia subsystem facilitates interoperability between the user terminal and the internet protocol network, thereby enabling the provision of an internet protocol based multimedia service using the user terminal.

<First Embodiment>

1 is a view for explaining a message format conversion apparatus according to a first embodiment of the present invention. Referring to FIG. 1, the message format converting apparatus 103 according to the first embodiment of the present invention includes a receiving unit 107 that receives a first message to be transmitted from the first terminal 101 to the second terminal 105. A conversion unit 109 for converting the format of the first message into the second message, an addition unit 111 for adding emergency processing request information to the second message, and transmitting the second message to the second terminal according to the emergency processing request information; It includes a transmission unit 115.

The receiver 107 receives a first message for transferring from the first terminal 101 to the second terminal 105. Here, the terminal includes a terminal capable of performing communication, and is not limited to a mobile communication terminal, and may include a personal computer. In addition, the message is not limited to the message between the mobile communication terminal, it may include a message of the form that can perform the communication between the terminal, such as e-mail. In addition, the message is not limited to the message in the form of text, but may include a message including multimedia content.

The conversion unit 109 converts the format of the first message into the second message. In this embodiment, the first terminal 101 is a terminal that can use the format of the first message, and the second terminal 105 can not use the format of the first message, but the format of the second message can be used. to be. Since the second terminal 105 cannot receive the service of the format of the first message, the conversion unit 109 converts the first message into the format of the second message. Therefore, by converting messages of different formats, it is possible to facilitate communication between terminals using different message formats.

The adder 111 adds urgent processing request information to the converted second message, and the transmitter 113 transmits the converted second message to the second terminal 105 according to the urgent processing request information. General messages are handled first-in, first-out (FIFO). However, certain message services may require real-time services or quality of service (QoS) functions to be added. Therefore, in order to provide a priority-based service for a message, emergency processing request information may be added. By doing so, there is an effect that both terminals can share a specific service that cannot be used in one terminal of both terminals performing communication. For example, suppose that terminal A and terminal B communicate with each other, and terminal A may use priority-based service, but terminal B cannot use priority-based service. Conventionally, even though terminal A transmits a message to terminal B using a priority-based service, terminal B has no choice but to receive the message in a FIFO method. According to the present embodiment, terminal B has a priority-based service added thereto. You can receive a message. Here, the priority-based service is possible because the emergency processing request information is added to the message.

On the other hand, the message format conversion apparatus 103 according to the first embodiment of the present invention further includes a status information check unit 115 for confirming the status information of the second terminal 105, the transmission unit 113 checks State information may be transmitted to the first terminal 101. Depending on the type of message service, the terminal may check the status information of the terminal and notify the other terminal. Therefore, when both terminals performing communication due to different message formats are not commonly provided with a service for confirming the status information of the terminal, by adding them, communication between both terminals can be made smoother.

Meanwhile, the message format converting apparatus 103 according to the first embodiment of the present invention may further include a terminal checking unit 117 for confirming whether the second terminal 105 supports a format for the first message. Can be. Before converting the format of the message, it may be checked whether the terminal of the communication counterpart supports the format of the message to be transmitted. If the other terminal supports the format of the message to be transmitted, the message is transmitted without additional format conversion. On the other hand, if the other terminal does not support the format of the message to be transmitted, the message is converted into a format that can be used in the other terminal.

Meanwhile, the transmitter 113 may determine the transmission order of the second message according to the emergency processing request information. The emergency processing request information may be classified according to the type of service. For example, it may be classified into first-in, first-out, priority-based transmission, or transmission of a received message within a predetermined time according to the type of message service.

Meanwhile, the first message is a message having an Internet Protocol Multimedia Subsystem (IMS) format based on Session Initiation Protocol (SIP), and the second message is a message having a Short Message Service (SMS) or Multimedia Message Service (MMS) format. Urgent processing request information may be added to the header of the SMS or MMS format. A message having a SIP-based IMS format can provide priority-based messaging and a status monitoring service of a conversation partner, and a service in an SMS or MMS format does not provide such a service. Therefore, when a message of an IMS format is to be delivered to a terminal that does not support an IMS format service, priority-based messaging and a status monitoring service of a conversation counterpart can be provided, thereby enabling smooth communication between both terminals. Do it.

By doing so, even if the second terminal does not support the status information service, the first terminal can check the status information of the second terminal.

On the other hand, the message format conversion method according to the first embodiment of the present invention may further include a step (S203) to determine whether the second terminal is a terminal that supports the format for the first message. When the second terminal supports the format for the first message, the second terminal transmits the first message as it is (S205). However, when the second terminal does not support the format for the first message, it converts the first message into a second message that is a message of a format supported by the second terminal (S207).

On the other hand, the step of transmitting to the second terminal (S211) may include the step of determining the transmission order of the second message according to the emergency processing request information.

5 is a diagram for explaining that emergency processing request information is added to an SMS message. Referring to FIG. 5, the SMS message includes a header part 501 and a data part 503. The header portion 501 may generally include data such as "length", "correlation number", "message type", "operation", "reserved", and the like. Urgent processing request information (Urgent Indicator) 505 may be included in the SMS message, and in particular, may be included in the header portion 501 of the SMS message.

6 is a view for explaining a specific embodiment of the present invention. Hereinafter, a specific embodiment will be described with reference to FIG. 6. A sender terminal (hereinafter referred to as an 'IMS sender terminal') that supports the IMS message format does not support an IMS message format and sends a message to a receiver terminal (hereinafter referred to as an 'SMS receiver terminal') that supports only an SMS format message. The case of transmission will be described as an example.

The IMS sender terminal transmits a message (S601). When transmitting a message to a terminal (SMS receiver terminal) that does not support SIP, the message is transmitted to an application server (AS) using a Message Session Relay Protocol (MSRP). Meanwhile, it is checked whether the terminal receiving the message supports the IMS message format (S603). If the receiving terminal supports the IMS message format, the existing IMS process is performed (S605). If the receiving terminal does not support the IMS message format, it converts to the message format supported by the receiving terminal (S607). Here, the conversion of the message format may be performed by activating an SMCI process in the SMS device and the Short Message Client Interface (SMCI) standard (S609). After the format is converted, the message is transmitted to the SMS receiver terminal (S617).

At this time, the QoS function for processing the corresponding message should be added according to the characteristics of the IMS service that emphasizes real-time. In addition, an algorithm for monitoring the status of the message receiver (SMS receiver terminal) is required.

First, the addition of the QoS function will be described. When the message format is converted, an "Urgent Indicator" for requesting urgent processing of the message is added to the message header (S611). The value of the "Urgent Indicator" can be expressed as an integer or a symbol.If the value is set, the "Urgent Indicator" is checked in the Short Message Service Center (SMSC) (S613), and the priority is based on the FIFO type queue. The process is urgently processed by switching to the queue method (S615). Even when the SMS receiver terminal transmits a response message to the IMS sender terminal, it may preferentially process the message by adding an "Urgent Indicator" to the response message.

Next, the state monitoring will be described. Status monitoring is performed through the XML Configuration Access Protocol (XCAP) message of the existing IMS. XCAP messages are a Diameter family protocol introduced for condition monitoring. Since the terminal receiving the existing SMS cannot process such a protocol, a different method is used for this. First, when the status of the corresponding SMS receiver terminal can receive a message, a response to wireless paging is performed, and the information can be managed together with the location information in the HLR (Home Location Register). Therefore, the receiver terminal is inquired through the HLR (S619). When the information value is transmitted to the home subscriber server (HSS), the HSS transmits the corresponding status information to the AS based on this, thereby reflecting the status information of the SMS receiver terminal (S621, S623). When the SMSC receiving the message from the AS inquires the HLR for processing the information, the status information is recognized as a message from the AS by referring to the "Indicator" value, and status management can be performed by notifying the status information to the HSS. . The status information is transmitted to the IMS sender terminal, and the IMS sender terminal user can check the status of the SMS receiver terminal (S625). HLR stores customer related information such as terminal location information, paging response time and service code.

The method of the present invention as described above may be embodied as a program and stored in a computer-readable recording medium (such as a CD-ROM, a RAM, a ROM, a floppy disk, a hard disk, or a magneto-optical disk). Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
