1 is a schematic diagram of a multimedia content providing system according to an exemplary embodiment of the present invention.

1, the multimedia content providing system according to an embodiment of the present invention, the calling terminal 110, the mobile communication network 120, the call waiting service server 130, the receiving terminal 140, the calling base station ( 150 and the called base station 160.

The calling terminal 110 is a device for receiving a call waiting service by wirelessly connecting to the mobile communication network 120 through the calling base station 150. A mobile communication network 120 such as a wideband code-division multiple access (WCDMA) terminal is provided. All types of terminals capable of accessing multimedia content.

The calling terminal 110 receives and plays multimedia contents for a call waiting service from a call waiting service server 130 when a call is originated, and subsequently plays multimedia contents provided during a call waiting time after the call is terminated.

That is, the calling terminal 110 attempts to make a call by calling a call to the called number input by the caller, and during the call waiting time when the call connection is attempted, the call waiting service server of the mobile communication network 120 ( 130) receives and plays the multimedia content corresponding to the called number. The multimedia content provided to the caller during the call waiting time is interrupted at the call connection time. After completing the call with the receiving terminal 140, the calling terminal 110 is played during the call waiting time according to the user's selection, and then plays the rest of the multimedia contents interrupted by the call connection.

Here, the multimedia content is a combination of various objects such as text, audio, image, video, computer graphics, animation, program code, etc. into one content in conformity with standards such as HTML, VRML, X3D, MPEG-4, and the like.

The mobile communication network 120 interworks with the calling base station 150 and the called base station 160, and provides a call service to the calling terminal 110 and the receiving terminal 140, including a base station controller, a wireless switchboard, and a network interworking device. To provide. In addition, the mobile communication network 120 connects the calling terminal 110 to the call waiting service server 130 so that the caller can be provided with the call waiting service. The device included in the mobile communication network 120 may vary depending on the type of the calling terminal 110 or the receiving terminal 140.

The call waiting service server 130 checks whether the call waiting multimedia content corresponding to the called party number of the call originator is set when the call is transmitted from the calling terminal 110 in association with the mobile communication network 120. Then, the set multimedia content is extracted and provided to the calling terminal 110 during the call waiting time.

In addition, after the call is terminated, the call waiting service server 130 provides the remaining part of the multimedia content which is stopped from playing at the time of the call connection in response to the request of the calling terminal 110.

The receiving terminal 140 is a terminal corresponding to the called number. The receiving terminal 140 wirelessly connects to the mobile communication network 120 through the called base station 160 and receives a call from the calling terminal 110 to perform a call connection. .

The calling base station 150 and the called base station 160 are network termination devices wirelessly connected to the calling terminal 110 and the receiving terminal 140, respectively, and transmitted from the calling terminal 110 and the receiving terminal 140, respectively. The service request is received, and the received service request is transmitted to the base station controller in the mobile communication network 120.

The aforementioned call waiting service server 130 transmits the multimedia content according to the call connection state of the calling terminal 110, that is, whether the call is waiting, in progress, or terminated, according to the current state of the calling terminal 110. 110 may be provided continuously.

After the call connection is made, a method of receiving the remaining portion of the multimedia content used when the call is waiting for the call 110 is representative of the following two methods.

First, downloading or streaming of multimedia content is interrupted when a call is connected, and after the call is completed, the rest of the multimedia content is provided again.

Specifically, the calling terminal 110 stops the playback of the multimedia content when the call is connected, and resumes the multimedia content after the call is terminated to play the rest of the multimedia content.

In this case, the call waiting service server 130 stops providing the multimedia content when the call is connected, and transfers the remaining portion of the multimedia content to the calling terminal 110 at the request of the calling terminal 110 after the call ends. It will then be provided.

Second, the multimedia content download is continued during the call connection.

Specifically, when the call is connected, the calling terminal 110 continues to download the multimedia content while the playback is stopped, and after the call ends, continues to play the multimedia content.

In this case, the call waiting service server 130 provides multimedia content until the download to the calling terminal 110 is completed, regardless of whether the call is connected or not.

Can provide. In addition, unlike the prior art in which the caller cannot hear the ring back tone after the incoming call, the caller using the system shown in FIG. 1 can listen to or resume the remaining portion of the multimedia content used in the call waiting service even after the call is terminated. have.

2 is a diagram illustrating an internal configuration of a mobile communication terminal according to an embodiment of the present invention, which illustrates the originating terminal 110 of FIG. 1.

2, a mobile communication terminal according to an embodiment of the present invention includes a main control unit 111, an input unit 112, a display unit 113, a call originator 114, a browser driver 115, and a browser 116. ).

The main control unit 111 manages all components such as the input unit 112, the display unit 113, the call origination unit 114, the browser device 115, and the browser 116 to control the mobile communication terminal. Control overall operation. In particular, the browser 116 is driven through the browser driver 115 to perform multimedia content processing when a call waiting service is provided.

The input unit 112 generates an input code using input data input by a caller, such as a called number, and a keypad, a touch pen, a mouse, and the like may be used as the input unit 112.

The display unit 113 displays a state of use of a battery, a reception strength of radio waves, a date and time, an operation state of the terminal, and the like in the standby state of the mobile communication terminal. When the call waiting service is provided, the multimedia content reproduced on the browser 116 is visually displayed.

The call originator 114 transmits a call to a called number that the caller inputs through the input unit 112 to establish a call.

The browser 116 accesses the call waiting service server 130 to play the multimedia content corresponding to the called number during the call waiting time, and after the call ends, plays the rest of the multimedia content.

The browser driver 115 detects a call connection state by interworking with the call originator 114 and controls whether the browser 116 is driven and whether multimedia content is played on the browser 116 according to the call connection state. In detail, the browser driver 115 plays the multimedia content on the browser 116 during the call waiting time, stops the multimedia content playback at the time of the call connection, and then plays the rest of the multimedia content after the call ends.

The browser 116 performs a download and playback operation of the multimedia content according to the content providing method of the browser driver 115.

For example, the browser driving unit 115 terminates execution of the browser 116 when a call is connected, and when the call connection is terminated, restarts the browser 116 to take over multimedia contents and then does not play the multimedia during the call waiting time. Play the rest of the content.

Or, when the call is connected, playback of the multimedia content is stopped, and the browser 116 continues downloading the multimedia content in the background. The browser 116 waits in the background until the call ends. After the call is terminated, the browser driver 115 causes the browser 116 to occupy the foreground to play the rest of the multimedia content.

The calling terminal 110 connected to the mobile communication network 120 and the mobile communication network 120 is capable of high-speed data transmission such as Wideband Code Division Multiple Access (WCDMA), Time Division Synchronous (TD-SCDMA), CDMA 2000, and the like. Therefore, the multimedia service including the video is possible.

In such an environment, since multi-access is possible, the calling terminal 110 performs signaling with a wireless switch in the mobile communication network 120 and then calls a circuit call for a call service. A packet call for receiving multimedia content for waiting can be simultaneously opened.

Accordingly, the originating terminal 110 may set a communication channel for the circuit call at the time when the caller presses the call button and sets the data channel for the packet call by driving the browser 116.

On the other hand, if the network connection time becomes longer, it is difficult to use the multimedia contents in the call waiting service because it takes a long time for the caller to actually check the multimedia contents after the browser 116 is driven.

Therefore, by utilizing the AlwaysOn function and the Concurrent environment, the service efficiency can be improved by minimizing the time required for downloading or real-time streaming of multimedia contents when providing the call waiting service.

In a concurrent execution environment in which several applications are run simultaneously, the network connection time is greatly reduced compared to the conventional method by minimizing the buffering using the always-on connection function and eliminating the time difference between the standby states. Therefore, the caller can directly listen to or listen to the multimedia content used in the call waiting service without waiting for a long time.

Hereinafter, a method of providing multimedia content according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

3 is a flowchart illustrating a method of providing multimedia content according to an embodiment of the present invention.

First, in step S110, the called party connects to the call waiting service server 130 using the receiving terminal 140 or another client computer, and sets the multimedia content to be used for the call waiting service of the receiving terminal 140.

Next, in step S120, the caller enters the incoming number of the receiving terminal 140 by operating the calling terminal 110, and by pressing the call button, the circuit call to the receiving terminal 140 via the mobile communication network 120 Try to connect the call by calling it.

Next, in step S130, the call originating terminal 110 at the time when the call is sent to the call waiting service server 130 to request a call waiting service. The call waiting service server 130 extracts the multimedia contents set corresponding to the called number and provides them to the calling terminal 110 so that the calling terminal 110 can play the corresponding multimedia contents during the call waiting time.

Step S130 may be subdivided into steps S131 to S135.

In step S131, the calling terminal 110 drives the browser 116 to open the packet call to receive the multimedia content.

In a multiple access environment, when the caller presses the call button of the calling terminal 110, the browser 116 may be driven, so that the calling terminal 110 simultaneously opens two channels for each circuit call and packet call such as WCDMA. Implement multiple access environment.

In step S132, the calling terminal 110 accesses the call waiting service server 130 through the browser 116, and transmits the recipient information including the called party number to the call waiting service server 130 at the time of connection.

In step S133, the call waiting service server 130 searches the database to extract the multimedia content corresponding to the called number included in the receiver information.

In operation S134, the call waiting service server 130 transmits the multimedia content extracted from the database to the calling terminal 110.

In step S135, the browser 116 of the calling terminal 110 downloads or streams the multimedia content provided from the call waiting service server 130 to reproduce the caller to see or hear.

In step S140, the call is connected between the caller and the receiver, and the caller terminal 110 stops playing the multimedia content at the time of the call connection. Then, after the call between the caller and the receiver is terminated, in step S150, the caller terminal 110 is provided during the call waiting time and then plays the rest of the multimedia content interrupted by the call connection.

In detail, in step S141, the receiving terminal 140 corresponding to the called number receives a call generated from the calling terminal 110 through the mobile communication network 120, and notifies the receiving terminal 140 of the incoming call.

In step S142, the originating terminal 110 recognizes the incoming call of the receiving terminal 140, terminates the browser 116 to stop the playback of the multimedia content.

In step S143, a call channel is established between the calling terminal 110 and the receiving terminal 140 to establish a call connection between the caller and the receiver.

As such, when the call is received, the browser 116 of the calling terminal 110 is terminated and the reproduction of the multimedia content is stopped.

After the call ends, in step S151, the browser 116 of the calling terminal 110 is driven again.

In step S152, when the browser 116 requests the resume of the previously interrupted multimedia content to the call waiting service server 130, the call waiting service server 130 calls the calling terminal 110. Transmit the rest of the multimedia content in response to the request.

When the multimedia content is provided, the browser 116 may be driven together with other applications according to the concurrent execution environment of the calling terminal 110, and the multimedia content may be downloaded or live streamed by AlwaysOn. Time can be minimized.

In step S153, the browser 116 of the calling terminal 110 continues to play the remainder of the unplayed multimedia content.

Here, the browser 116 may play the multimedia content after the remaining part of the multimedia content is downloaded, or may be played by real time streaming.

In the case of real-time streaming, the browser 116 plays the multimedia content in real time without downloading in the state connected to the call waiting service server 130 instead of downloading and playing the multimedia content. In this case, even before all the multimedia content is transmitted, since the browser 116 starts the presentation of the multimedia content, the playback time is shortened and it is advantageously hardly affected by the storage capacity in the terminal.

When streaming, if the speed at which the calling terminal 110 receives the multimedia content is too fast, the data is streamed while storing the extra data in the buffer.

4 is a flowchart illustrating a multimedia content providing method according to another embodiment of the present invention.

Since steps S110 to S130 of FIG. 4 perform the same operations as those of FIG. 3, detailed description thereof will be omitted.

In step S240, a call is made between the sender and the receiver. Then, after the call between the caller and the receiver is terminated, in step S250, the caller terminal 110 plays the remainder of the multimedia content not played during the call waiting time.

Specifically, in step S241, the receiving terminal 140 corresponding to the called number receives a call generated from the calling terminal 110 through the mobile communication network 120, and informs the receiving terminal 140 of the incoming call.

When the call is received, the calling terminal 110 proceeds to step S242 to stop playing the multimedia content and move the browser 116 to the background.

In step S243, a call channel between the calling terminal 110 and the receiving terminal 140 is established to make a call connection between the caller and the receiver.

In step S244, the calling terminal 110 continues without interrupting the download of the multimedia content after the call connection. That is, even during a call connection between the calling terminal 110 and the receiving terminal 140, the browser 116 continues to download the multimedia contents.

Then, in step S245, the call between the sender and the receiver is terminated.

After the call ends, the calling terminal 110 proceeds to step S251 to move the browser 116 back to the foreground (Foreground) to drive.

In step S252, the browser 116 of the calling terminal 110 continues to play the rest of the multimedia content except the part played during the call waiting time.

According to another embodiment of the present invention, since the download of the multimedia content is continued during the call, when the calling terminal 110 plays the multimedia content after the call is terminated, the time taken for buffering when downloading or streaming can be shortened.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that.
