Hereinafter, with reference to FIG. 1, in order to perform the operation of the terminal according to the present invention, the organic operation relationship between each component of the terminal will be described in detail.

The terminal may generate or store content. The content generated or stored by the terminal may include various formats such as still images, music, voice, and video. For example, the still images or videos may be generated through the camera 121 of the A / V input unit 120. . Then, it may be generated using music or the voice microphone 122. The terminal may receive various contents through the wireless communication unit 110 and store them in the memory 160. The terminal may include a content generating unit for generating content using an internal component of the terminal, for example, the camera 121, the microphone 122, and the like. An image, that is, a picture is described as an example, and the following embodiments of the present invention may be applied to other contents in the same concept.

If the still image is generated through the camera 121, the terminal may transmit it to another terminal to be transmitted through the mobile communication module 112. Most of the pictures can be sent to the mail system immediately after taking a picture with the camera 121. This is true even if two friends each have a terminal together. Still images generated by one terminal must be manually transmitted to the desired terminal even if the number of the images is large. Or if the storage capacity of the terminal is exceeded, you must delete the picture taken before sending it to another user. To overcome this, the controller 180 of the terminal of FIG. 1 may transmit a still image generated by performing a location checking process to another terminal.

The terminal may store the number of another user's terminal in the memory 160. The terminal may find the location of another terminal registered in the phone book stored in the memory 160 of the terminal within a predetermined radius. The controller 180 may drive a location search application stored in the memory 160 to find a terminal within a predetermined radius among the numbers of the terminals registered in the phone book, and generate a location list of the terminals within the predetermined radius.

The location list of the terminal registered in the phone book can be obtained in the following embodiments. First, a description will be given of a process of obtaining a location of a terminal as follows.

The terminal may obtain location information using a global positioning system (GPS) capable of tracking a location. GPS places multiple satellites in each orbit of the earth and allows the terminal to communicate with four or more satellites. The terminal may receive a signal including a specific code transmitted from the satellite through the location information module 115 to obtain a current location including longitude, latitude, and altitude data of the terminal. The terminal may know when the signal from the satellite is transmitted, and the location information may be obtained by the time taken for the satellite signal to reach the terminal.

Location information of terminals may be managed based on the base station. For example, when the location information module 115 of the terminal calculates its own location using GPS information, the information can be transmitted to the base station through the mobile communication module 112 of the wireless communication unit 110. The base station may generate location information for each terminal in a database and update it.

The terminal may receive location information of terminals whose numbers are registered in their telephone book from the base station. The terminal may receive, from the base station, location information of terminals, which are within a predetermined range, centered on its own terminal among the above registered terminals. Accordingly, the terminal may transmit the content stored in the memory 160 to the terminals based on the received location information of the terminals. The terminal may transmit the content to the registered terminals through the wireless communication unit 110 using the numbers of the terminals registered in the phone book. The user may instruct the control unit 180 to transmit content to the terminals within a predetermined distance as described above through the user input unit 130. Therefore, content held by one terminal can be easily transferred to other terminals to share the content.

The output unit 150 may express a content transmission application according to a user's command when the user wants to transmit content according to the example of the content transmission method described above. The content transmission application may display the terminals of a predetermined distance received by the wireless communication unit 110 from the base station in the form of a map on the display unit 151 together with the position of the terminal. The user of the terminal may select a desired terminal among the terminals having a location expressed by the content transmission application and transmit the content. A schematic conceptual diagram of transmitting content is illustrated in FIG. 5. The content delivery application can be executed with the content creation. For example, when the user generates the content with the camera 121, the content transmission application is driven and the user can immediately send the generated content to the surrounding terminal. Therefore, the content can be easily shared, and the hassle of separately sending it later can be eliminated.

Meanwhile, the location list of the terminal can also be obtained by the following embodiment. The terminal may obtain a location list of terminals located at a certain radius based on their location based on the wireless communication network. The terminal may obtain a location list of neighboring terminals based on the position of the relative terminal of the base stations using the distance between four or more base stations.

The base station may transmit a system parameter including latitude and longitude information to the terminal. The terminal may receive a system parameter including latitude and longitude information of the base station and update it every time it moves. Therefore, when the terminal communicates with a base station, the terminal may use the latitude and longitude data of the base station as the location information of the terminal. Therefore, when the terminal requests the base station for location information about terminals registered in the phone book, the base station may transmit the location information of the neighboring terminals to the requesting terminal as information on the base station communicating with the registered terminals. When a terminal searches for location information of a terminal registered to the terminal within a certain distance, the terminal may easily transmit content to the searched terminals, so that some error may occur in the location information of the terminal. The terminal may obtain the location information of the terminals registered in the phone book and compare the map information stored in the memory 160 to display the location of the counterpart's terminal on the display unit 151.

During typical operation of a wireless communication system, BS 270 receives a reverse link signal from various terminals 100. At this time, the terminals 100 are connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by a particular base station 270 is processed within by the particular base station 270. The data generated as a result of the processing is transmitted to the connected BSC 275. BSC 275 provides call resource allocation and mobility management functionality, including the organization of soft handoffs between base stations 270. In addition, the BSC 275 transmits the received data to the MSC 280, and the MSC 280 provides an additional transmission service for connection with the PSTN 290. Similarly, PSTN 290 connects with MSC 280, MSC 280 connects with BSCs 275, and BSCs 275 send BSs 270 to transmit a forward link signal to terminals 100. ).

When the base station communicates with the terminals and the terminal requests location information of the terminal at a certain distance from the terminal, the base station may transmit GPS data or system parameters to the terminal. The GPS data of the terminals may be received from the terminals, and the GPS data of the terminals may be transmitted to the desired terminal, respectively.

5 illustrates a conceptual diagram of a content transmission method according to the present invention.

The first terminal 410 includes a camera or the like for generating content. For example, the camera may generate content and transmit the generated content to terminals 420 and 430 within a certain distance based on the location information. It is assumed that the second terminal 420 and the third terminal 430 are at a predetermined distance, for example, a radius of 5 km from the first terminal 410. The base station 450 may transmit content between the terminals 410, 420, and 430 or transmit location information of each terminal to another terminal. Here, the base station 450 may include the wireless communication network illustrated in FIG. 4, and may also be a management network that separately manages only location information of the terminals, for example, GPS information. That is, the exemplary base station 450 may function to relay or relay content and location information between terminals, respectively.

The first terminal 410, the second terminal 420, and the third terminal 430 may notify their own location information by transmitting location information obtained from the GPS system to the base station, respectively. Alternatively, the first terminal 410, the second terminal 420, and the third terminal 430 may receive a signal including the location information of the base station from the base station and use the information as its location information. Alternatively, the position of each terminal can be obtained from the system parameter transmitted by the base station for the distance between the base station and the terminal with which the terminal communicates. Accordingly, the terminal may obtain location information of its own terminal as location information of the base station and system parameters transmitted by the base station. When the terminal obtains its own location information, it can transmit it to the base station, respectively.

Accordingly, the first terminal 410, the second terminal 420, and the third terminal 430 may obtain their own location information, and the base station 450 may have the location information of the terminals communicating with the base station. . Since the base stations can communicate with each other, the first base station can transmit location information of the terminal connected to the second base station from the second base station and transmit the location information to the terminal connected to the first base station. Therefore, the terminal can obtain the position information of the terminal which is a certain distance from its own position information.

The first terminal 410 generates the content. The first terminal is registered in the contact list of the first terminal and can search for a terminal number located within a predetermined position. When the first terminal 410 requests the base station 450 for location information of terminals that are registered, the base station 450 receives the location information of the second and third terminals 420 and 430 satisfying the corresponding condition. 410 may be notified. Therefore, the first terminal can transmit the content generated using the multimedia messaging system (MMS) to the second and third terminals 420 and 430 received from the base station 450. Therefore, the sharing of the generated contents with the terminals in the remote location can be simplified, and the hassle of transmitting the contents one by one can be eliminated.

The first terminal receives and stores the content to be generated or transmitted (S110). The content is not limited to the content generated by the first terminal, but may be content in which content received from another device is stored. The location information may be GPS based information or information based on a wireless communication network such as a base station with which the first terminal communicates.

The first terminal is registered in the contact list of the first terminal and receives location information of the second terminal located at a predetermined distance from the first terminal (S120). The first terminal can obtain the location information of the second terminal from the base station. The second terminal is a terminal whose location information is located within a predetermined distance from the first terminal of the first terminal and registered in the contact list of the first terminal. The first terminal may execute the content transmission application to obtain location information of the second terminal satisfying the above-described condition.

The first terminal transmits the content generated using the wireless communication network to the second terminal (S130). The first terminal can transmit the content to the second terminal using the MMS system. When the first terminal implements the content transmission application and obtains the location information of the second terminal, the first terminal may control whether to transmit the content to the second terminal through the content transmission application. That is, when the location information of the third terminal other than the second terminal is received in step S120, the first terminal may select only a desired terminal among the second terminal and the third terminal to transmit content.
