The present invention relates to a recording medium which can be used.

Currently, in order to provide a communication service by text (or small amount of data) in a mobile communication network, a short message service (SMS) is used to communicate between terminals or between a content providing server and a terminal. In this method, the calling terminal (or the content providing server) forms a short message and transmits the short message to the called terminal through the short message transmitting server (SMSC), and the short message transmitting server transmits the short message in a scale & store manner.
Therefore, there is a significant time delay before the short message transmitted from the calling terminal arrives at the called terminal, and there is no way for the calling terminal user to know whether the short message arrives at the called terminal and the called terminal user confirms the short message. . In addition, since only a small amount of text is used as a transmission message, it is difficult to transmit and receive data such as a long message, a voice, an image, a video, a music file, and the like.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention improves the shortcomings of the non-real-time short transmission method by the conventional short transmission method (SMS), and provides a real time message transmission and reception in an evolved mobile communication network (cdma1x, cdma1x Ev-Do, IMT2000, etc.) To achieve the same effect as doing.

However, the present invention is not limited to the mobile communication network, but is not limited to the wired and wireless Internet (WEB, WAP / ME), intranet, LAN, wireless LAN, telephone network (PSTN), mobile Internet (WiBro), terrestrial broadcasting network. It should be noted that the present invention can be applied to DMB (Digital Multimedia Broadcasting) broadcasting network.

Therefore, the calling / receiving terminal can be replaced with not only a synchronous / asynchronous mobile communication terminal, but also a PC, a notebook computer, a hand-held PC, a PDA, a portable Internet terminal, a broadcast receiver, a DMB phone, and the like. It should be noted that it is not limited to that kind.

In addition, although the following assumes a Short Message Service (SMS) message, it should be noted that a message such as an EMS (Enhanced Messaging Service) or an MMS (Multimedia Messaging Service) is also possible.

1 is an exemplary configuration of a system for providing a real-time message call service according to the present invention. In a more preferred embodiment, a mobile communication network environment will be described as an example.

The message call server 30 is located in a mobile communication network or the like to process a message call, and serves as an intermediary for setting up a message call between mobile communication terminals (outgoing / receiving terminals 10 and 20). In addition, when the calling terminal 10 cannot be connected to the called terminal 20 (for example, when the called terminal is in a call, or when the power is turned off or located in a shadow area, etc.), it connects to the message mailbox 50. In this manner, a message (text, voice, image, video, music file, etc.) may be transmitted to the destination terminal 20 in a scale and store manner in a manner similar to the existing short message transmission service. Of course, the size of the transmitted message is much larger than the short transmission method.

The message call server 30 will be described in more detail with reference to FIG. 4 below.

2 is a flowchart illustrating a method for real-time message call service according to the present invention, which illustrates a service procedure using a Session Initiation Protocol (SIP) signal.

As shown in Figure 2, the message call service method according to the present invention, the call terminal (attempt to call the call) to the destination terminal 20 through the message call server 30 largely from the originating terminal 10 Step 1 (201 ~ 203), if the destination terminal 20 is not assigned an Internet address (IP address), the second step of assigning an IP address from the mobile communication network (at this time, if the destination terminal 20 is already an IP address If the state has been assigned, the process for the second step can be omitted), the called terminal 20 is the user's response to the call attempted to connect (for example, the user calls the call button of the called terminal 20 ( Press the SEND button) to complete the call session in response to the session (steps 204 to 207), thus real-time messages between the two terminals 10 and 20 connected to the message call server 30. For example, text, voice, image, video, music files, etc.) to send and receive calls In the fourth step (209 to 215) to proceed, when the call is completed between the caller / called terminal (10, 20) to request the end of the call (hook-on) in one terminal (10 or 20) connected call session A fifth step (216 ~ 218) to end.

In particular, in the fourth step (208 to 215), since the message communication is already made in the state that the SIP session is already established, it is possible to send and receive messages in real time, and the message (for example, text, voice) transmitted from the calling terminal 10 position , An image, a video, a music file, etc.) may be received from the called terminal 20, so that the called terminal 20 may receive the message.

Looking at this in detail.

The first steps 201 to 203 are a process of requesting a setup for a message call from a calling terminal 10 to a called terminal 20 via a message calling server 30 (attempting a call session).
That is, the calling terminal 10 transmits an INVITE message, which is a SIP message for setting up a call session, to the called terminal 20 through the message call server 30 (201 to 203). At this time, the addresses of the calling terminal 10 and the called terminal 20 are recorded in the INVITE message. In this case, the calling terminal 10 is already registered in the message call server 30. In this case, the term 'registration' means that registration has been performed through the REGISTER message, which is a SIP message, or has already been registered in the message call server 30 in a similar manner.

Here, if the message call server 30 receives the INVITE message (201), first checks whether the destination terminal 20 is registered, and if registered, transmits the INVITE SIP message to the destination terminal (20).
However, if the destination terminal 20 is not registered, the message call server 30 converts the short message (SMS message) through the short message transmission server (SMSC) 40 and transmits it (202, 203). That is, FIG. 2 shows an example in which the called terminal 20 is not registered. When the short message transmission server (SMSC) 40 receives a short message (SMS message) from the message call server 30 (202), A general SMS message of the mobile phone is transmitted to the called terminal 20 (203), and the called terminal 20 receives a short message (SMS message).

In this case, the called terminal 20 may additionally ring a call that the message call service has been received, and the calling terminal 10 may provide a service so that a call connection sound is heard. By doing so, the service can be differentiated from the existing short service method (SMS).

In the second step, when the called terminal 20 receives the SMS message, the receiving terminal 20 analyzes the SMS message, recognizes the message call service, and is assigned an IP address. Of course, if the destination terminal 20 has already been assigned an IP address, this process does not go through.

In the third step (204 ~ 207) receives the SMS message (the first step) and the IP terminal (the second step), the receiving terminal 20 receives the SMS message is analyzed by the originating terminal 10 In response to the sent message (here, an SMS message, and an INVITE SIP message if registered), a 200 OK message, which is a response SIP message, is transmitted (204, 205), and the calling terminal 10 receives a 200 OK message and responds to it. By sending an ACK message to the destination terminal 20 (206, 207), the call session of the message call service is connected and is ready to proceed with the message call. In the middle of this process, the message call server 30 manages call session information.

In the fourth step 208 to 215, a text, voice, image, video music file, etc. are transmitted and received in real time using a SIP message MESSAGE while a call session is connected. In this case, a similar SIP message may be used in addition to the MESSAGE, but MESSAGE is illustrated as an example in FIG. 2.
Here, the "MESSAGE" may include attributes such as the type of text (voice, voice, image, video, music file, etc.) and the length of the message to be sent.
That is, the calling terminal 10 transmits a message (text, voice, image, video, music file, etc.) to the called terminal 20 through the message call server 30 (208, 209), and the called terminal 20 attaches thereto. In response to the 200 OK message is transmitted to the calling terminal 10 (210, 211). In addition, in response to the message (text, voice, image, video, music file, etc.) transmitted from the calling terminal 10, the called terminal 20 also sends a message to the calling terminal 10 through the message call server 30. (Text, voice, image, video, music file, etc.) can be transmitted (212,213), and the calling terminal 10 transmits a 200 OK message to the called terminal 20 in response (214,215).

The fifth step (216 to 219) is a process of ending a session after performing a message call between the incoming and outgoing terminals 10 and 20 (after the fourth step). At this time, the call termination may be performed by anyone who is called or called. However, FIG. 2 illustrates a process of first terminating the calling terminal 10. That is, the calling terminal 10 transmits a BYE message, which is a SIP message for terminating the session (216, 217), and receives a 200 OK message from the called terminal 20 in response (218,219) to terminate the session.
At this time, at the end of the session, session information managed by the message call server 30 is also terminated, and necessary statistical information and billing information can be generated.

3 is a flowchart illustrating a service process when a called terminal is incapable of communication in the real-time message call service method according to the present invention, and shows a service procedure using a SIP signal.

That is, FIG. 3 illustrates a call processing procedure for a case where the called terminal 20 cannot connect a call in the second and third steps of FIG. 2 or there is no response even after a predetermined time elapses.
Referring again to the first steps 201 to 203 of FIG. 2, the originating terminal 10 requests the setup terminal for the message call to the destination terminal 20 through the message call server 30 (attempting a call session). .
3, the calling terminal 10 transmits an INVITE message, which is a SIP message for setting up a call session, to the called terminal 20 through the message call server 30 (301 to 303).
At this time, if the message call server 30 receives the INVITE message (301), it checks whether the destination terminal 20 is registered, and if registered, and transmits to the destination terminal 20 through the INVITE SIP message.
However, if the destination terminal 20 is not registered, the message call server 30 converts the short message (SMS message) through the short message transmission server (SMSC) 40 and transmits it (302 and 303). That is, FIG. 3 illustrates an example in which the called terminal 20 is not registered. When the short message transmission server (SMSC) 40 receives the short message (SMS message) from the message call server 30 (302), A general SMS message of the mobile phone is transmitted to the called terminal 20 (303), and the called terminal 20 receives a short message (SMS message).

However, when the called terminal 20 is not available (no answer, busy, etc.), the sixth step of the message call server 30 connects the call to the message mailbox 50 of the called terminal 20 (in this case, (304, 305) notifying that the call terminal cannot be connected to the calling terminal 10, and the message terminal 50 of the called terminal 20 stores the message to be transmitted by the calling terminal 10 in the message mailbox 50 of the called terminal 20. Step 7 (306 ~ 309), if the call with the destination terminal 20 after a certain time, the contents stored in the message mailbox 50 is transmitted to the destination terminal 20 to the destination terminal 20 to scale the incoming And eighth steps 310-318 to provide delivery.

Looking at this in detail.

In the sixth step, when the called terminal 20 is incapable of communication (for example, no answer, busy, power-off, etc.), the message calling server 30 recognizes that the communication is incapable of calling, and the calling terminal 10 It is a process (304,305) informing that the connection to the message mailbox 50 because the call can not be connected to the side.
That is, the message call server 30 transmits a 200 OK response message to the calling terminal 10 to inform that the called terminal 20 is in a disabled state (304). At this time, it is notified that the call is not available, the message mailbox 50 will be notified that the message to be sent to the destination terminal 20 is stored later. Of course, if the message mailbox service is not provided, there is no need to do this. In FIG. 3, it is assumed that the message mailbox 50 is placed.

Thereafter, when the originating terminal 10 receives the 200 OK message (304), it sends an ACK message in response to this to enter a session with the message mailbox service of the message call server 30 (305).

The seventh step 306 to 309 is a process of transmitting a message through a session connected to the message mailbox 50. The message at this time may be the same kind as the message transmitted to the called terminal 20 (that is, the message transmitted to the called terminal 20 before recognizing that the call is not available).
At this time, while the message mailbox service session is connected, the text, voice, image, video music file using the SIP message MESSAGE, as when transmitted to the destination terminal 20 before recognizing that the call is not available in FIG. Etc. are stored in the message mailbox 50. In this case, a similar SIP message may be used in addition to the MESSAGE, but MESSAGE is illustrated as an example in FIG. 3. Here, the "MESSAGE" may include attributes such as the type of text (voice, voice, image, video, music file, etc.) and the length of the message to be sent.
That is, when the calling terminal 10 transmits a message (text, voice, image, video, music file, etc.) to the message call server 30 (306), the message call server 30 sends it to the message mailbox 50. After storing (307,308) in response to the 200 OK message is transmitted to the calling terminal 10 (309).
If the receiver is stored in the message mailbox 50 as described above, when the called terminal 20 is in a state capable of receiving a message (callable state), the stored message is transmitted to the called terminal 20.

In the eighth step 310 to 318, when the message call server 30 recognizes that the called terminal 20 is enabled to make a call, it establishes a session for a message call with the called terminal 20 and transmits the stored message. The call is terminated after all stored messages have been transmitted. In this case, the SIP message used performs the same function as the SIP message used in the calling terminal 10 and the called terminal 20 in FIGS. 2 and 3.
The eighth step (310 to 318) is similar to the well-known message mailbox service process, but for the purpose of understanding, based on the mailbox message transmission process of Figure 3, first, the message call server 30 is called terminal 20 When the called terminal 20 is in a callable state, it is converted into a short message (SMS message) through the short transmission server (SMSC) 40 and transmitted (310, 311). This shows an example in which the called terminal 20 is not registered. When the short message transmitting server (SMSC) 40 receives a short message (SMS message) from the message call server 30 (310), the called terminal 20 In step 311, a general SMS message of the mobile phone is transmitted (311), and the called terminal 20 receives a short message (SMS message).
In this case, as described above in step 203 and step 303 of FIG. 3, the called terminal 20 may ring a call that the message call service is received, and the call may be made from the calling terminal 10. The service may be provided so that the connection sound is heard. By doing so, the service can be differentiated from the existing short service method (SMS).
As described above, when the called terminal 20 receives the SMS message, the receiving terminal 20 analyzes the SMS message, recognizes the message call service, and receives an IP address. Of course, if the destination terminal 20 has already been assigned an IP address, this process does not go through.
Thereafter, the receiving terminal 20 receiving the SMS message and assigning the IP address analyzes the received SMS message and sends a 200 OK message, which is a response SIP message to the message sent by the calling terminal 10, to the message call server 30. In step 312, when the message call server 30 receives the 200 OK message, the message call server 30 sends an ACK message to the destination terminal 20 in response thereto (313) and the call session of the message call service is connected to prepare for the message call. Is completed. In the middle of this process, the message call server 30 manages call session information.
With the call session connected in this way, the message call server 30 receives the text, voice, image, video music file, etc. stored by the caller stored in the message mailbox 50 in real time using the SIP message MESSAGE. The terminal 20 transmits (315), and the destination terminal 20 receives it (315). In this case, as described above, similar SIP messages may be used in addition to MESSAGE, but MESSAGE is used as an example.
Here, the "MESSAGE" may include attributes such as the type of text (voice, voice, image, video, music file, etc.) and the length of the message to be sent.
That is, the message call server 30 transmits a mailbox message (text, voice, image, video, music file, etc.) stored in the message mailbox 50 to the called terminal 20 (315), and the called terminal 20 ) Sends a 200 OK message to the message call server 30 in response (316).
Thereafter, after the message call is performed between the message call server 30 and the called terminal 20, the session may be terminated. At this time, the call termination may be performed by anyone in the message call server 30 or the called party first. However, FIG. 3 illustrates a process of first terminating the message call server 30. That is, when the message call server terminal 30 transmits a BYE message, which is a SIP message for terminating a session, to the destination terminal 20 (317), a 200 OK message is received from the destination terminal 20 in response thereto (318). End the session.
At this time, at the end of the session, session information managed by the message call server 30 is also terminated, and necessary statistical information and billing information can be generated.
The eighth step (transmission of the mailbox message when the called terminal is available) is described based on a known mailbox service process, the description of FIG. 2, and the service procedure of FIG. 3. 2 and the service procedure of FIG. 3) are merely matters to be apparent to those skilled in the art.

Now, the configuration of the real-time message call service system (message call server 30) according to the present invention will be described in more detail with reference to FIG.

As shown in FIG. 4, the real-time message call service system (message call server 30) is a message (text, voice, video, transmitted / received from a terminal (caller / receiver terminal 10, 20) through a mobile communication network). A message processor 32 for receiving a music file through TCP (Transmission Control Protocol) / IP (Internet Protocol) (or UDP (User Datagram Protocol) / IP or similar transmission protocol) and analyzing the message; If the message is a message call call-related message, the call session information management unit 33 for processing it, the terminal registration information processing unit 38 for storing it in the terminal registration information database 70 if the registration information related message of the terminal; Mailbox information processing unit 34 to process when the call is not available (20), a new long text processing unit 35 for converting the long information to suit the short transmission method, and the service to manage the subscriber information It is composed of the correction processing unit 34, the charging processing unit 37, which manages the charging information in the message communication service.

In particular, a short transmission server (SMSC) matching unit 39 is provided to interwork with the short transmission service of an existing mobile communication network to provide a message call service as needed.

The TCP / IP processor 31 matches the mobile communication network with TCP / IP and transmits the SIP message through TCP (UDP) / IP or a similar transport protocol. That is, the module performs TCP / IP matching with the mobile communication network to send and receive SIP messages.

The message processing unit 32 transmits a SIP message between the calling terminal 10 and the called terminal 20 through the message call server 30 after the TCP / IP connection is established with the mobile communication network. Parsing the SIP message (or the destination terminal 20) to perform the role of error verification, retransmission, authentication and transaction processing. In addition, when the SIP message is transmitted from the message call server 30 to the called terminal 20 (or the calling terminal 10), a SIP message is generated to meet the standard, and the called terminal 20 is transmitted through the TCP / IP processing unit 31. (Or the transmitting terminal 10). For example, in FIG. 2, the message call server 30 may receive and transmit a SIP message called MESSAGE.

The call session information management unit 33 serves to establish a call between the terminals 10 and 20 for a message call. At this time, the representative SIP message connecting the call is an INVITE / 200 OK / ACK message, call session information management to manage the INVITE / 200 OK / ACK incoming message to the message call server 30 originating terminal 10 and incoming It manages the session for the call of the message call between the terminal 20.
That is, at the time of establishing the call session, when the terminating terminal 20 is registered with the service as described in FIG. 2, an INVITE SIP message is transmitted to the terminating terminal 20, and the terminating terminal 20 is transmitted. When the response SIP message (200 OK message) is transmitted (204 of FIG. 2), it is transmitted to the calling terminal 10 (205 of FIG. 2), and the calling terminal 10 transmits an acknowledgment (ACK) message thereto. 2 (206 in FIG. 2) is transmitted to the destination terminal 20 (207 in FIG. 2) to form a call session of the message call service.
However, when the terminating terminal 20 is not registered in the service, it notifies the terminating terminal 20 that the message call service has been received by an SMS message through interworking with the short message transmission server (SMSC) 40 (203 of FIG. 2). After receiving the SMS message, the called terminal 20 analyzes the SMS message, recognizes that the message is a call service, checks whether the IP address has been previously assigned, and receives an IP address when it is not assigned (second step of FIG. 2). In response to the SMS message, a SIP message (200 OK message) is transmitted to the calling terminal 10 (204 and 205 of FIG. 2), and a response (ACK) message is received from the calling terminal 10 (206 and 207 of FIG. 2). ) Form a call session of the message call service.

Here, the main management content plays a role of performing call session management such as call connection and call cutting similarly to general mobile phone calls.

The terminal registration information processing unit 38, when the terminals 10, 20 registered in the message call service turn on the power or perform a program for other services, the terminal registration information (for example, number, IP address, etc.). ) Is registered with the message call server 30 to be authenticated. At this time, the SIP message used is representative of the REGISTER, other similar messages may be used.
In addition, the terminal registration information processing unit 38 receives the registration message of the SIP analyzed by the message processing unit 32 and records it in the terminal registration information database 70. It is assumed that it plays a role similar to that of a home location register (HLR) of a general mobile communication network.

When the destination terminal 20 is turned off or cannot receive a message, the mailbox information processing unit 36 stores a message transmitted from the originating terminal 10 in a long mailbox information database (ie, a message mailbox 50) and then receives the message. When the terminal 20 is receivable (that is, when the call becomes available), the stored message is transmitted to the called terminal 20.
At this time, the method for transmitting a message to the destination terminal 20, when the destination terminal 20 registers with the message call server 30 through the REGISTER SIP message is transmitted through the TCP / IP processing unit 31 through the SIP message And a method for transmitting through a short text transmission server (SMSC) 40 through a general text transmission of the mobile phone.
Here, in order to transmit to the short message transmitting server (SMSC) 40, the short message transmitting server (SMSC) 40 is transmitted using a protocol with the short message transmitting server (SMSC) 40.

The short transmission server matching unit 39 is a module that matches the short transmission server (SMSC) 40, and processes the protocol for matching with the short transmission server (SMSC) 40 of the mobile communication network.

The new palm print processor 35 is responsible for creating a message in the mailbox information processor 36 and the message processor 32 in accordance with the standard of the short message transmission server (SMSC) 40 to be sent to the destination terminal 20. This module performs. In general, for short transmission, a string of about 80 bytes is used. Of course, it should be noted that the limitation of this length may change depending on the type and evolution of the mobile communication network.

The service information processing unit 34 is a module for managing subscribers subscribed to the message call service. This module is responsible for processing the service subscriber information database 60.

The charging processor 37 manages the charging information of the message call service. At this time, the billing information may be managed by combining information such as the call time of the call session, the amount of messages transmitted. In addition, when necessary, the billing information may be charged to the subscriber by transmitting the billing information managed in accordance with the billing system of the mobile communication service provider.
In summary, the real-time message call service system (message call server 30) according to the present invention includes a service information processing unit 34 for managing a message call service subscriber and a terminal registered with a service (caller / receiver terminal 10, 20)) a terminal registration information processing unit 38 for managing the state of the mobile terminal, a TC P / IP processing unit 31 for transmitting a SIP message in conformity with the mobile communication network, and a message from the originating terminal 10 registered with the service. In response to a call request, a call session information management unit 33 for establishing a call session by connecting a call to the called terminal 20 and completing a call session in response to an incoming call, and the call session is formed, the calling terminal 10 Message processing unit 32 for real-time transmission of the SIP message (text, voice, image, video, music file, etc.) transmitted by the IP address to the called terminal 20 assigned the IP address through the TCP / IP processing unit 31. Include.
In this case, when the called terminal 20 is registered with a service, when the INVITE SIP message is transmitted to the called terminal 20 and the called terminal 20 transmits a response SIP message (200 OK message) thereto, This is transmitted to the calling terminal 10, and when the calling terminal 10 transmits an acknowledgment (ACK) message, it transmits it to the called terminal 20 to form a call session of the message call service. However, when the terminating terminal 20 is not registered in the service, the terminating terminal that the message call service is received as an SMS message through interworking with the short text transmitting server (SMSC) 40 through the short text transmitting server matching unit 39 ( 20), the receiving terminal 20, upon receiving the SMS message, analyzes the SMS message, recognizes that the message call service, check whether the IP address has been pre-assigned, when not assigned the IP address, SMS Send a reply SIP message to the message.
