It can provide a speed of 2.4Mbps in the forward direction and can provide a speed of about 135kbps even in the reverse direction of transmitting data from the terminal to the network.

On the other hand, the text message service provided through the terminal is a basic service for sending messages between terminals, and initially it was able to send and receive only short messages of about 80 characters or less, but recently, as the construction facilities of the mobile communication network have developed Not only long texts but also images and sound sources can be transmitted together.

However, an additional service for providing various contents such as text and image related to a voice call to a user during a voice call has not been provided yet.

The present invention proposes a new mobile communication system and an additional service providing method thereof, which enables a user to immediately transfer a requested content during a voice call to a corresponding terminal to which the voice call is connected.

More specifically, a method of providing an additional service of a mobile communication system according to an embodiment of the present invention includes a first step of connecting a voice call with a terminal through a mobile communication network; And a second step of transmitting a facility message to the terminal including a voice call identifier and one or more data fields defining attributes of data content to be provided in association with the voice call during the voice call. Including, there is an advantage that the user can provide more accurate and faster information desired by the voice call connection.

In addition, the mobile communication system according to an embodiment of the present invention generates a facility message including one or more data fields defining attributes of data content to be provided in association with the voice call to a terminal to which the voice call is connected. Including the server to transmit the transmission efficiency of the wireless channel has the advantage that can provide a more diverse and convenient additional services to the user.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a mobile communication system according to an embodiment of the present invention.

As shown in FIG. 1, a mobile communication system according to an embodiment of the present invention comprises a base station, a control station, and a mobile switch, and configures a mobile communication network, and is connected to an MSC through a mobile communication network to provide additional services. It includes a service server 20, 20 'to provide.

A base station transceiver subsystem (BTS) wirelessly connects to the user terminal 10 to control a connection state of a connected terminal and allocates a channel for a call during a voice call or a data call.

A base station controller (BSC) interworks with a mobile switching center and is connected to a plurality of base stations to manage an operation state of each base station. In this case, some control stations may interwork with a data service device, for example, a PDSN, to provide a data service.

Mobile Switching Center (MSC) is a device that provides circuit switching services and call channel switching functions, and is connected to a control station to control the operation of voice calls or various additional services provided by each communication company. In addition, it establishes a call channel, and allows the user terminal to be connected to various peripheral devices and external networks.

The user terminal 10 may be provided with a voice call service with another terminal 10 through a mobile communication network, and may be connected with a data service device such as a PDSN to receive desired specific contents from a plurality of service servers.

The service server 20, 20 'may be connected to the calling terminal by the voice call according to the above-described operation, and may transmit predetermined content data related to the voice call content in a separate additional control message. In addition, instead of directly including content data to be provided, path data such as an address where the corresponding content is stored, for example, a URL, may be included in the additional control message and transmitted. At this time, if the URL data is transmitted, the data call is immediately set up so that the corresponding content is transmitted to the calling terminal, or when the user's request command is generated, the content data is transmitted.

In this case, the additional control message is a message that can be transmitted and received through the caller side switch that controls the voice call connection, in the present specification will be described as an example of a facility message (facility message) in accordance with the 3GPP standard, but is not limited thereto. The specific data structure of the facility message will be described later.

That is, the mobile communication system according to an embodiment of the present invention, for the terminal 10 to which the voice call is connected, generates an additional control message for storing additional content and related information related to the voice call, and allocates the allocated voice call. And a service server 20 for transmitting the additional control message to the connected terminal through a channel.

2 is a block diagram illustrating an internal configuration of a service server and a terminal in a mobile communication system according to an embodiment of the present invention.

The service server 20 may be connected to a PDSN or an MSC through an IP network, and is a server for providing contents requested by a user or providing related additional services during a voice call, and searching for data contents related to the voice call. A control unit 100 and a message generation unit for generating an additional control message including an identifier indicating the voice call associated with the retrieved data content or the connection information of the retrieved data content according to the media type or size of the retrieved data content ( 110).

In addition, the content storage unit 120 stores a variety of content information that can be provided to the terminal user, so that the control unit 100 can search for the corresponding content. In this case, the content storage unit 120 may be physically included in the service server 20 or separately separated as a content server to transmit and receive data with the service server through a predetermined communication method.

That is, for example, it may include an information guide server such as a location information guide server or various content servers provided with an ARS (Audio Response System).

ARS is a system that transmits the user input contents such as telebanking or phone banking to the host computer, converts the data stored in the database of the host computer into voice and sends it back to the user, according to an embodiment of the present invention A ringer providing server, a background image providing server, and the like, which are accessible through the service server 20 may correspond to the service server 20 and are not limited to a specific content providing server.

In addition, when conducting a voice call with an agent through ARS, the agent generally uploads the information configured during the voice call to a server connected in real time, wherein the additional control message is transmitted through the server connected to the agent. If the call is generated and transmitted to the connected terminal, the server may be the service server 20 according to an embodiment of the present invention.

In addition, an application server stored in the user terminal 10 and provided with various application data for automatically accessing the wireless data network when executed according to a user's input may also be included as the service server 20, and may include content or an application. Any server that is built to provide a separate service other than a voice call to a user terminal may be included as a service server.

In this case, as described above, the content related data transmitted to the calling terminal through the additional control message may be directly included in a specific field in the additional control message, and in some cases, such as a url where the corresponding content is located. Route data may be included.

More specifically, the additional control message is a message that is transmitted and received through the exchange together in the voice call connected state, if it is transmitted from the service server in the voice call connected state is included in the message because it is preferably received in the terminal connected call There may be a limit on the amount of packets of the content that can be transmitted.

Therefore, in the case of contents having a capacity over a certain amount of packet or a medium generally having a considerable amount of packet amount, rather than including the contents directly in the additional control message, the contents include url data of the server in which the contents are stored. May help to be received by the calling terminal more quickly.

Further, according to this, the originating terminal 10 receiving the additional control message includes the UI 60 and the controller 50 to read the received additional control message and to receive the content additionally if content data is directly stored in the message. The stored content data may be stored and output on the UI 60.

In this case, if it is determined that the route data is included in the received additional control message, the designated content may be downloaded by automatically or manually connecting the data call to the corresponding address according to the user's selection of the calling terminal 10. . In addition, it can be downloaded automatically or manually according to the media type of the corresponding content, and by reading the field value in the additional control message, it is possible to select whether the downloaded content is stored in the memory of the terminal 10.

Referring to the additional service providing method of the mobile communication system according to an embodiment of the present invention as described above are as follows.

First, the data structure of the facility message according to an embodiment of the present invention will be described.

3 is a diagram illustrating a data structure of a facility message in a mobile communication system according to an embodiment of the present invention.

A facility message is a means for providing an additional message defined in the 3GPP standard, and a message format is defined as shown in FIGS. 3 (a) and 3 (b). The present invention focuses on the fact that contents related to the voice call can be provided to the user terminal during the voice call using the facility message.

More specifically, in the embodiment of the present invention, as shown in FIG. 3 (c), a new data field is defined in the component area of the facility message, and items such as the type of content, the length of the content, and the content to be transmitted are defined. By allowing the terminal to recognize the identification, it is possible to enable appropriate identification processing according to the content to be provided by the terminal side.

In the mobile communication system according to an embodiment of the present invention, the facility message is largely divided into "SS protocol discriminator", "Transaction identifier", "Facility message type" and "Facility" regions as shown in FIG. Can be configured.

In this case, the "SS protocol discriminator" area is a delimiter indicating that the message is for providing supplementary service (SS), and in the "Transaction identifier" area, a call delimiter for identifying which voice call is associated with the facility message. The information is stored.

In the “Facility” area, various data for providing an additional service may be stored. The “Facility” area may include “Facility IEI”, “Length of Facility contents”, and “component, as shown in FIG. 3 (b). "Area, and in the mobile communication system according to an embodiment of the present invention, the related content data can be provided to the terminal by utilizing the facility area.

On the other hand, the "component" area in the "Facility" area may be composed of a plurality of fields, as shown in Figure 3 (c), for classifying the type of content stored in the other field to text, binary, or url A content type identifier field F1, a content length field F2 in which a length value of the corresponding content is stored, and a content field F3 in which content data to be actually included are stored may be defined.

The "component" region may be defined in more detail. As shown in FIG. 3 (d), "component type tag", "component length", "Invoke ID tag", "Invoke ID length", and "Invoke ID" "," Operation Code tag "," Operation Code length "," Operation Code "field may be included, and" Parameters "field is included. In addition, depending on the selection, it may include "Linked ID tag", "Linked ID length", and "Linked ID" fields.

A field having a field name ending with "tag" is a content type identifier field for identifying a content data type, in which a code defining a type of content or a message is stored. In addition, a field having a field name ending with "length" stores a length (capacity) value of the corresponding content or message. The corresponding content is stored in the remaining fields ending with "tag" or "length".

For example, a code for designating a URL data type may be stored in the “component type tag” field. In addition, the "Parameter" field may include the actual value of the URL data or data composed of ASN.1 Notation.

4 is a flowchart illustrating a method for providing an additional service of a mobile communication system according to an embodiment of the present invention. FIG. 4 (a) is a flowchart showing an overall method of providing an additional service, and FIG. 4 (b) accordingly. It is a flowchart illustrating a method for providing an additional service operated by a terminal.

First, in step S10, when the terminal 10 inputs a dial number or the like for connecting to the service server 20 through a voice call, the calling terminal side exchange reads the forwarded number in step S20 and the service server 20 Call setup is established when the voice call connection is established with the service server 20 and the voice call is established with the service server 20.

In step S30, if the user wants to provide predetermined additional information related to the voice call currently connected to the user of the calling terminal 10 or if the user requests for the predetermined additional information, the service server 20 reads it and provides it. Search for related content about additional information to be desired.

The service server 20 may recognize the user's request information through a voice recognition function, or may recognize the request information by inputting a key button for transmitting the request information. The method of recognizing the request information of the user through the voice in the service server 20 may be implemented in various ways in addition to the above-described example, and thus is not limited to the above-described example.

In step S40, the retrieved content data according to the operation of step S30 is stored in the component area of the facility message. In this case, the service server transmits information on the message, url, data type, and data size together in the component area of the facility message, and determines whether the transmitted message is immediately displayed on the screen of the terminal. The service server may control whether to automatically discard the facility message by including call identifier information in the facility message.

Next, in step S50, the facility message generated by the service server is transmitted to the terminal, and in step S60, the received facility message is read and the corresponding content is output on the screen of the terminal.

The process in step S60 will be described in more detail as follows.

When the voice call is connected in step S110, in step S120, the facility message sent from the service server is received by the terminal.

Next, in step S130, the "transaction identifier" assigned to the facility message is read, and in step S140, the read "transaction identifier" is compared with the "transaction identifier" of the currently connected call.

As a result of the comparison, when each "transaction identifier" is not the same or the terminal is not currently in a call connection state, in step S150, the facility message received by the terminal may be automatically discarded.

However, if each "transaction identifier" is the same, in step S160, the "operation code" field of the component area of the received facility message is read out, and in step S170, a message such as content is stored directly in the facility message, or Determines whether the url indicates content.

Therefore, when the "operation code" is read as having predetermined data stored directly, in step S180, the "Invoke ID tag" field is read to determine whether the data stored in the facility message is text or binary data (image), In step S190, a corresponding viewer is executed accordingly.

Next, in step S200, the data stored in the facility message is output on the screen of the terminal through the executed viewer.

In step S210, when the "operation code" field includes a code indicating rul, the call connection request signal for data call connection is transmitted to the base station. In step S220, the data connected to the corresponding url according to the call connection setting. Allow the call to be established.

Next, in step S230, content data is received from the corresponding url through the set data call. In step S240, the set data call is disconnected, and the received data is read and displayed on the screen of the terminal.
