This is done by assigning a menu corresponding to a specified function and then displaying a specified menu according to a predetermined request input so that when a user selects the menu, a predetermined function according to the selected menu is performed. Through a process to perform a predetermined function according to the menu to be performed. In addition, recently, if a function is required to be performed by the user by iconizing each menu, the corresponding icon selection is made accordingly, and the function is performed by selecting the icon accordingly. The proposed method is to further increase the convenience of.

In particular, the mobile communication service subscribers send and receive text messages using SMS, which enables simple message transmission. SMS refers to a two-way text service that can send and receive short messages between mobile communication terminals. This allows a subscriber to receive a message through a public telephone network, data communication network or the Internet when the subscriber sends a short sentence of 255 bytes of information to another mobile communication subscriber in Korean or English including numbers or symbols.

For reference, a mobile communication terminal is a terminal which a user can carry and communicate with while moving. The mobile communication terminal uses a forward channel for receiving text and a reverse channel for transmitting. In this case, the text information mainly uses SMS, and when received, a Mobile Termination (MT) SMS is used, and a Mobile Origination (MO) SMS is used. In general, a mobile communication system uses a data burst message of a paging channel of a CDMA mobile communication system when received, and if the user is busy, a corresponding text message is a data burst message of a forward traffic channel. Send a message. In addition, a text burst message of an access channel is used to transmit a text message, and a data burst message of a reverse traffic channel is transmitted when a text message is in use.

However, in the case of short messages, the maximum amount of editing is limited to 255 bytes. In the case of multimedia messages, the amount of message editing is increasing, such as the maximum amount of editing being 10,000 characters.

The MMS supplementary service means that various content providers (CPs) provide various supplementary application services using an MMS system. These CPs use a separate system and tools to provide services for creating a special MMS and to charge for information.

However, the existing MMS supplementary services are mainly provided by a web-based editing tool, or by downloading a virtual machine (VM) tool to a terminal. For this reason, the market has shrunk so that only limited users can use these services. Looking at this in detail.

Therefore, it is in charge of the role and business of the gateway system that provides a function of relaying service use by the MO SMS to all MMS supplementary services of the mobile communication network.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration of a multimedia messaging service (MMS) relay system to which the present invention is applied.

Incoming and outgoing terminals 11 and 19 are personal digital assistants (PDAs) and handheld PCs capable of SMS and MMS through mobile communication networks, public telephone networks (PSTN), wired / wireless LANs, etc. , A mobile terminal (MS: Mobile Station) including a mobile communication terminal such as a laptop, a cellular phone or a personal communication service (PCS) phone, a next generation mobile communication terminal such as an IMT-2000 phone or a CDMA-2000 phone. It uses a forward channel (Forward Channel), and when using a reverse channel (Reverse Channel), it is clear that any terminal capable of sending and receiving SMS, MMS regardless of its kind.

In general, a mobile communication network includes a base station transceiver base system (BTS), a base station controller (BSC), a mobile switching center (MSC), a visitor location register (VLR), a home location register ( HLR: Home Location Register). For reference, the function of each component of the mobile communication network will be described.

The base station (BTS) connects the calling and receiving terminals (MS) 11 and 19 to the base station controller (BSC), the digital channel unit (DCU: Digital Channel Unit), the time / frequency control unit (TCU: Timing / Frequency Control) Unit), radio frequency unit (RFU) and global positioning system (GPS). In addition, the base station (BTS) performs a wired / wireless conversion function of communicating with the originating and receiving terminals (MS) 11 and 19 over the air and communicating with the base station controller BSC by wire.

The base station controller BSC connects the base station BTS to the exchange MSC to coordinate the connection between the base stations BTS and performs a signal processing function for communication between the base station BTS and the exchange MSC.

On the other hand, the MSC has a visitor location register (VLR) and processes mobile communication subscriber calls in association with the home location register (HLR) and the SMS gateway 12. The exchange MSC is connected to the base station controller BSC to perform call setup and release functions of the MS 11 and 19, and to perform various functions related to call processing and additional services.

The visitor location register (VLR) then provides subscriber information associated with the call destination (MS) 11, 19 while the call destination terminal (MS) 11, 19 is in an area controlled by the visitor location register (VLR). Is a database for temporarily storing the information of the call destination terminal (MS) 11, 19 and the subscriber whose location is registered in the area in which they are in charge from the home location register (HLR) and temporarily store the information. It is mounted.

The home location register (HLR) is a database that manages various information of mobile subscribers by being connected to an exchanger (MSC) and an SMS gateway 12. The home location register (HLR) performs a function such as registration of subscriber locations by interworking with various exchanges (MSCs). It stores permanent information and location information of called and receiving terminals (MS) 11 and 19 and subscribers, and supports various functions related to call processing and additional services by interacting with visitor location register (HLR). In particular, the home location register (HLR) stores the triggering information according to the service used by the subscriber.

The SMS gateway 12 is typically a server in the mobile communication network, and relays SMS transmission and reception with a plurality of SMS centers (SMSC) 15 in the mobile communication network.

The MMS relay server 13 is responsible for receiving and analyzing the MO SMS and converting and transmitting the same through the corresponding MMS servers 17-1 to 17-n.

The terminal information server 14 is a server existing in a mobile communication network. The terminal information server 14 manages a function of a user terminal and informs about the information.

SMS center (SMSC) 15 is connected to MMS relay server 13 and plays a key role in SMS routing function, sets SMS parameters, interprets destination address of incoming SMS message, and analyzes corresponding network. Send it to the element.

The MMS center (MMSC) 16 is connected to the MMS relay server 13 and plays a key role in the MMS routing function, sets MMS parameters, interprets a destination address of an incoming MMS message, and corresponds to a corresponding network. Send it to the element.

The MMS servers 17-1 to 17n are servers of various content providers CP that provide various additional services using an MMS network.

Then, a method of relaying MMS supplementary services existing in a mobile MMS network using MO SMS will be described.

First, when a caller sends an MO SMS (called number + service + option + message) through the calling terminal 11 (101), the SMS gateway 12, which is normally present in the mobile communication network, is an MMS relay server (as the called number). 13) and transmits the message to the MMS relay server 13 (102). At this time, the called number is the access number of the MMS relay server 13, 'service type', 'service option', 'message' is loaded on the MO SMS and transmitted to the MMS relay server 13.

Thereafter, the MMS relay server 13 inquires whether the destination terminals 19-1 and 19-2 are terminals capable of receiving the MMS, to the terminal information server 14 (103). In this case, when the destination terminals 19-1 and 19-2 are not MMS-receivable terminals, the destination terminals 19-1 and 19-2 are converted to general SMS and received through the SMS center 15 (SMSC) 15-1. To send).

Then, the MMS relay server 13 finds out the service type and options included in the MO SMS and requests MMS generation from the MMS servers 17-1 to 17-n of the type (104). At this time, the 'service option', 'message', and 'translation topic' are transmitted together to the MMS server 17-1 to 17-n. Then, the MMS server 17-1 to 17-n generates an appropriate MMS message by referring to the received service option and message, and then transmits the generated MMS message to the MMS relay server 13 (104). At this time, the MMS server 17-1 to 17-n may convert the mobile terminal with reference to the caller's subscription information.

Next, the MMS relay server 13 transmits the received MMS message to the called terminal (MMS receiving terminal) 19-2 through the MMS center (MMSC) 16 (105, 106). Thus, the MMS message is received at the called party through the MMS center (MMSC) 16.

As such, the MMS relay server 13 may receive an MMS message from the MMS servers 17-1 to 17-n and transmit it to the called terminal (MMS-receivable terminal) 19-2 (see FIG. 2 below). However, the present invention is not limited thereto, and the MMS servers 17-1 to 17-n may be configured to directly transmit an MMS message to a called terminal (MMS-receivable terminal) 19-2 (see FIG. 3 below).

Thereafter, the MMS relay server 13 charges the information usage fee according to the MMS transmission result (107). At this time, the MMS relay server 13 charges through the billing server 18, and later settles with the MMS servers 17-1 to 17-n.

In addition, the MMS relay server 13 requests an SMS message transmission to an SMS center (SMSC) 15 in order to notify the sender of the transmission result (108), and transmits the transmission result through the SMS center (SMSC) 15. The terminal 11 is notified (109).

In the above, the MMS message conversion function of each MMS server 17-1 to 17-n may be incorporated in the MMS relay server 13 to provide a service. In addition, the MMS relay server 13 may incorporate a conversion function of some services, and the conversion function of some services may depend on external MMS servers 17-1 to 17-n. In addition, a conversion function may be built in the MMS relay server 13 to form a network with a plurality of MMS relay servers 13.

In addition, a relay gateway (G / W) may exist separately for the MMS transmission without directly passing through the MMS center (MMSC) 16. In addition, a relay G / W may exist for SMS transmission.

In addition, there may exist a network using WAP PUSH as MMS for MMS transmission, or there may be a network for converting and transmitting MMS to WAP PUSH for supporting an implementation terminal. Here, the WAP PUSH is a method of pushing information in a WAP manner through a PPG (Push Proxy Gateway) or URL-CALLBACK SMS.

In addition, a service may be provided in this manner by using an enhanced messaging service (EMS) and a long message service (LMS), which have more functions than SMS and have a smaller function than MMS. In this case, the LMS is a service used by a domestic mobile communication company, and may transmit a message longer than an SMS, and may also transmit an image. In addition, EMS is an international standard. It is a service that can mix and transmit images and is based on SMS. The types are Basic EMS and Extended EMS.

2 is a flowchart illustrating a method for relaying a multimedia messaging service (MMS) according to the present invention, in which an MMS is relayed to an MMS server 17 and an MMS is transmitted, but the MMS relay server 13 sends the MMS. The case of doing it directly is shown.

First, when the caller sends the MO SMS through the calling terminal 11, the message (MO SMS) is received by the destination number to the MMS relay server 13 (201). At this time, the MO SMS includes a 'service access number', 'calling number', 'called number', 'service type', 'service option', 'message' and the like. In this process, the SMS gateway 12 detects that it is transmitted to the MMS relay server 13 as a called number on the MO SMS and transmits the MO SMS to the MMS relay server 13.

Thereafter, the MMS relay server 13 searches whether the destination terminals 19-1 and 19-2 are terminals capable of receiving an MMS (202). This is done by inquiring the terminal information server 14.

As a result of the search, if the destination terminals 19-1 and 19-2 are not MMS-receivable terminals, that is, terminals capable of receiving only SMS, the procedure of FIG. 4 is followed.

As a result, if the destination terminal 19-1 or 19-2 is a terminal capable of receiving MMS, it is searched whether the 'type of service' is a registered MMS supplementary service, and the MMS server 17-1 to 17- that supports the service. find out information related to n) (203). This information is as shown in Table 1 below.

That is, the MMS relay server 13 checks whether the 'service type' requested by the caller is registered and the 'connection information' is valid (204). Then, the received 'service option' information is compared with the 'support service option' of management information (204). If everything is not suitable follow the procedure of Figure 4 below.

However, if it is determined appropriate in step 204, the subject of the message is identified (see Figure 5 below) (205).

Then, the MMS relay server 13 determines whether the MMS relay server 13 should transmit or whether the MMS service servers 17-1 to 17-n should transmit (206).

If the MMS service servers 17-1 to 17-n do not transmit, follow the procedure of FIG. 3 below.

On the other hand, when the MMS relay server 13 transmits, it connects to the corresponding MMS service servers 17-1 to 17-n according to the 'connection information' of the management information shown in Table 1 below, and the 'service option'. In step 207, the MMS service is requested by transmitting the message and the conversion subject to the corresponding MMS service servers 17-1 to 17-n.

Then, the MMS service server 17-1 to 17-n first searches whether the caller is a subscriber of the MMS service server 17-1 to 17-n (208), and if the service subscriber is a caller, the caller is the corresponding MMS. The 'personal service information' set in the service servers 17-1 to 17-n is used to generate the MMS message. Then, the MMS service server 17-1 to 17-n generates a suitable MMS message by using the received 'conversion subject', 'service option', 'message', 'personal service information', etc. (209) In step 210, the generated MMS message is transmitted to the MMS relay server 13.

Thereafter, the MMS relay server 13 transmits the MMS message to the called terminal 19-2 of the 'called number' (211), in which the transmission is usually made through the MMS center (MMSC) 16.

Thereafter, the MMS relay server 13 charges the information usage fee through interworking with the billing server 18 according to the MMS transmission result, in which case billing is performed by 'billing information' of 'management information' (212). . This is divided between the business entity of the MMS relay server 13 and the business entity of the corresponding MMS service servers 17-1 to 17-n according to the settlement rate of the 'billing class'.

Finally, the MMS relay server 13 notifies the sender of the service result by SMS (213), where the transmission is typically notified to the calling terminal 11 via the SMS center (SMSC) 15.

For reference, information managed to relay from the MMS relay server 13 to the MMS service servers 17-1 to 17-n is shown in Table 1 below.

3 is a flowchart of another embodiment of a multimedia messaging service (MMS) relaying method according to the present invention, which illustrates a case in which the MMS server 17 directly sends an MMS by relaying an MO SMS to the MMS server 17.

First, when the caller sends the MO SMS through the calling terminal 11, the message (MO SMS) is received by the destination number to the MMS relay server 13 (301). At this time, the MO SMS includes a 'service access number', 'calling number', 'called number', 'service type', 'service option', 'message' and the like. In this process, the SMS gateway 12 detects that it is transmitted to the MMS relay server 13 as a called number on the MO SMS and transmits the MO SMS to the MMS relay server 13.

Thereafter, the MMS relay server 13 searches whether the destination terminals 19-1 and 19-2 are terminals capable of receiving an MMS (302). This is done by inquiring the terminal information server 14.

As a result of the search, if the destination terminals 19-1 and 19-2 are not MMS-receivable terminals, that is, terminals capable of receiving only SMS, the procedure of FIG. 4 is followed.

As a result, if the destination terminal 19-1 or 19-2 is a terminal capable of receiving MMS, it is searched whether the 'type of service' is a registered MMS supplementary service, and the MMS server 17-1 to 17- that supports the service. find out information related to n) (303). This information is as shown in Table 1 above.

That is, the MMS relay server 13 checks whether the 'service type' requested by the caller is registered and the 'connection information' is valid (304). Then, the received 'service option' information is compared with the 'support service option' of management information (304). If everything is not suitable follow the procedure of Figure 4 below.

However, if it is determined appropriate in step " 304 ", the subject of the message is identified (see Figure 5 below) (305).

Then, the MMS relay server 13 determines whether the MMS relay server 13 should transmit or whether the MMS service servers 17-1 to 17-n should transmit (306).

If the MMS service servers 17-1 to 17-n transmit, the procedure of FIG. 2 is followed.

On the other hand, when the MMS relay server 13 transmits, it connects to the corresponding MMS service servers 17-1 to 17-n according to the 'connection information' of the management information of the above [Table 1], and the 'service option', The MMS requests the MMS generation by transmitting the message and the conversion subject to the corresponding MMS service servers 17-1 to 17-n (307). At this time, the corresponding MMS service server 17-1 to 17-n notifies to directly transmit the MMS.

Then, the MMS service server 17-1 to 17-n first searches whether the caller is a subscriber of the MMS service server 17-1 to 17-n (308), and if the subscriber is a service subscriber, the caller is the corresponding MMS. The 'personal service information' set in the service servers 17-1 to 17-n is used to generate the MMS message. The MMS service server 17-1 to 17-n generates an appropriate MMS message by using the received 'transformation subject', 'service option', 'message', 'personal service information', etc. (309). In operation 310, the generated MMS message is transmitted to the called terminal 19-2 of the called number through the MMS center (MMSC) 16, and the result is notified to the MMS relay server 13 (311). .

Thereafter, the MMS relay server 13 charges the information usage fee through interworking with the billing server 18 according to the MMS transmission result, in which case billing is performed by 'billing information' of 'management information' (312). . This is divided between the business entity of the MMS relay server 13 and the business entity of the corresponding MMS service servers 17-1 to 17-n according to the settlement rate of the 'billing class'.

Finally, the MMS relay server 13 notifies the originating terminal 11 of the service result via the SMS center (SMSC) 15 (313).

FIG. 4 is a detailed flowchart illustrating a process of transmitting MO SMS to MT SMS in a multimedia messaging service (MMS) relay method according to the present invention. FIG. 4 is a diagram illustrating a process of relaying MO SMS to MMS service servers 17-1 to 17n. When it can not, it shows the procedure of converting to normal SMS and transmitting.

First, when the caller sends the MO SMS through the calling terminal 11, the message (MO SMS) is received by the destination number to the MMS relay server 13 (401). At this time, the MO SMS includes a 'service access number', 'calling number', 'called number', 'service type', 'service option', 'message' and the like. In this process, the SMS gateway 12 detects that it is transmitted to the MMS relay server 13 as a called number on the MO SMS and transmits the MO SMS to the MMS relay server 13.

Thereafter, the MMS relay server 13 searches whether the destination terminals 19-1 and 19-2 are terminals capable of receiving an MMS (402). This is done by inquiring the terminal information server 14.

As a result of the search, if the destination terminals 19-1 and 19-2 are terminals capable of receiving MMS, the procedure of FIG. 2 or FIG. 3 is followed.

As a result of the search, if the destination terminals 19-1 and 19-2 are not MMS-receivable terminals, that is, terminals capable of receiving only SMS, they are converted to general SMS (403). In other words, the 'outgoing information' is the MT SMS caller's call number and callback (CALL-BACK) number (returning number in normal text SMS, which is usually the caller's number is entered, but managed as a separate area can put a different number) And the 'called number' as the called number of the MT SMS. Then, 'message' is assigned to the message part of the MT SMS.

The MMS relay server 13 transmits the SMS message to the called terminal (terminal capable of receiving SMS) 19-1 via the SMS center (SMSC) 15 (404).

Thereafter, the MMS relay server 13 charges the information usage fee through interworking with the charging server 18 according to the SMS transmission result, but charges the same as the SMS charge system.

Finally, the MMS relay server 13 notifies the calling terminal 11 of the service result via the SMS center (SMSC) 15 (406).

As such, when the MMS relay server 13 cannot transmit the MMS, the MMS relay server 13 can always complete the service normally. That is, the MMS relay server 13 has an advantage that the sender's message can always be transmitted to the called party even in exceptional circumstances. The first message sent is SMS, and the incoming message becomes SMS and the same charge is executed as SMS, so the sender does not have any complaints. However, the existing MMS service server (17-1 ~ 17n) in this case just marked as not possible and did not provide a service.

FIG. 5 is a detailed flowchart illustrating a message conversion subject determination process in a multimedia messaging service (MMS) relaying method according to the present invention, and illustrates a procedure for determining a subject to be converted by analyzing the propensity of a message.

Among the 'service options', the most common and important option in most MMS supplementary services is the 'translation subject' how to convert the message. In addition, the conversion to the MMS suitable for the user's message content is the most important factor in this service. Thus, the present invention automatically determines this transformation subject, allowing each transformation module to generate an MMS appropriately for this subject. It is also possible to modify this subject to receive input from the sender, but this greatly degrades service usefulness.

According to the results of the current MMS message usage log, MMS messages are relatively expensive and are used for a relatively clear purpose. Its purpose is such as 'love', 'celebration', 'friendship', 'encouragement', 'thank you', 'apple'. In addition, if it is impossible to determine, it is possible to properly generate MMS by using 'weather', 'time', 'seasonal' and 'season' well. Therefore, in the present invention, the subject of the message is identified through the following procedure.

First, based on the statistical analysis of the MMS message words, the rule-based analysis (501). Here, 'rule-based analysis' is a general technique of 'data mining', and is a method of determining a group to which a sample belongs according to a result by formalizing a set of rules defined for a sample. In other words, a typical 'data mining' technique is to determine a result by using a predetermined logical logic as a rule. By this analysis, 'love', 'celebration', 'friendship', 'encouragement', 'audit', 'apple', etc. are distinguished (502,503). This classification result is a result of the statistically high frequency and can be modified somewhat.

Thereafter, based on the result of analyzing the MMS message as learning, 'group-based analysis' is performed (504). Here, 'group-based analysis' is a general technique of 'data mining', by performing learning through a set of samples to generate training data for a group to which the sample belongs, and to which group the input sample belongs to. How to decide. That is, as a general 'data mining' technique, it is to analyze the messages into groups by learning, and to analyze which group the input message belongs to. The results are divided into 'love', 'celebration', 'friendship', 'encouragement', 'audit', and 'apple' (505,503).

Then, it is determined whether the current time is a special season (506). Suitable seasons for MMS include 'New Year', 'Valentine', 'Vacation Season', 'Christmas' and 'Seasonal Season' (507). In such a case, this is decided.

On the other hand, it is determined whether the area of the current called party or the caller is in a special weather state (508), and if it is a special weather such as 'snow' or 'rain', this is determined (509).

On the other hand, it is determined whether the time of the current called party or caller is a special time (510), for example, in the case of 'morning', 'night', etc., in particular, in the case of early morning or late night (511). ).

On the other hand, the current 'season', 'time' themes or 'other' is treated (512). Here, the term "other" refers to processing as a subject neutrally. Thus, each server generates an MMS using a neutral image or melody.

In steps "506" to "512", a random factor is caused to act. In other words, even if it is determined as "Yes" in the "506" step, for example, there is a 100% probability that it does not go to "Yes". This factor increases the probability of application to the lower node. That is, the "510" step is more likely to apply than the "506" step. That is, the "510" stage is of lower value than the "506" stage.

In the above, a 'subject' may be partially modified or added. In addition, each decision node may be partially modified or added, and the order may be modified.

Now, the configuration of the MO SMS for this service will be described.

MO SMS uses one of these methods depending on the terminal function or service status.

For this service system, the MO SMS includes a service access number (called number for connecting to the MMS relay server 13), service type (information indicating MMS supplementary service to be relayed by the MMS relay server 13), service option ( When the MMS supplementary service creates an MMS, additionally necessary information, which may or may not be different for each MMS supplementary service, the called party number (phone number to which the message will be sent), the calling party number (phone number to which the message is sent) , Message content information to be transmitted, and the like.

Typically, a plain text SMS message conforming to the IS-637 standard includes a called number (called party number), a calling number (called party number), a message (sent message), and a callback number (phone number to be sent, typically the sender). Phone number).

In the following [Table 2] to [Table 4] 'service option' may not be used.

[Table 2] below is a case where 'service access number' and 'service type' are shown through the called number. Therefore, the called number is different depending on the type of service. The 'calling number' is put in the CALL-BACK number part.

[Table 3] below is the same as [Table 2] above, but the method of inputting the 'calling number' at the front of the message.

[Table 4] below shows a case where 'service access number', 'service type' and 'called number' are shown through the called number. Therefore, the called number is different depending on the type of service and the called number. Depending on the type of service, it has a PREFIX number followed by the called number. For example, '1588 + 011XXXXXXX'.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention as described above, by allowing the sender to simply use the desired MMS supplementary services through MO SMS, there is an effect that can contribute to the activation of MMS supplementary services.

In particular, the present invention has the effect of improving the service efficiency by analyzing the message and converting it to a suitable MMS according to the subject of the transformation to be transmitted.
