For example, at least one of the configurations 260, 121 to 250, and 152 described as being disposed in the second rear case 235, such as the camera 121 of the second body, It is also possible that the first rear case 225 is mounted to the rear case 225. In such a case, there is an advantage that the configuration (s) disposed in the first rear case 225 in the closed state is protected by the second body 205. Further, even if the camera 121 of the second body is not separately provided, the camera 121 of the first body may be configured to be rotatable so that the camera 121 of the second body can be photographed up to the photographing direction .

The terminal 100 shown in Figs. 1 to 3 is operable in a communication system capable of transmitting data through a frame or a packet, including a wired / wireless communication system and a satellite-based communication system .

Hereinafter, a communication system capable of operating a terminal according to the present invention will be described with reference to FIG.

The communication system may use different air interfaces and / or physical layers. For example, wireless interfaces that can be used by communication systems include, but are not limited to, Frequency Division Multiple Access ('FDMA'), Time Division Multiple Access ('TDMA'), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications Systems (UMTS) (especially Long Term Evolution (LTE)), Global System for Mobile Communications (GSM) . Hereinafter, for the sake of convenience of description, the description will be limited to CDMA. However, the present invention is applicable to all communication systems including CDMA wireless communication systems.

4, the CDMA wireless communication system includes a plurality of terminals 100, a plurality of base stations (BSs) 270, and base station controllers (BSCs) 275 , And a mobile switching center ('MSC') 280. MSC 280 is configured to be coupled to a Public Switched Telephone Network (" PSTN ") 290, and is also configured to be coupled to BSCs 275. BSCs 275 may be coupled in pairs with BS 270 through a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL or xDSL. Thus, a plurality of BSCs 275 may be included in the system shown in FIG.

Each BS 270 may comprise at least one sector, and each sector may comprise an omnidirectional antenna or an antenna pointing to a particular direction of radial from BS 270. [ In addition, each sector may include two or more antennas of various types. Each BS 270 may be configured to support a plurality of frequency assignments and each of the plurality of frequency assignments has a specific spectrum (e.g., 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency assignment may be referred to as a CDMA channel. BS 270 may be referred to as a Base Station Transceiver Subsystem (BTSs). In this case, the word "base station" may be referred to as a combination of one BSC 275 and at least one BS 270. [ The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS 270 may be referred to as a plurality of cell sites.

Also, at least one of the GPS satellites 300 may optionally or additionally be responsible for satellite DMB transmission.

Among the typical operations of a wireless communication system, the BS 270 receives a reverse link signal from the various terminals 100. At this time, the terminals 100 are in the process of connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by the particular base station 270 is processed by the particular base station 270. The data resulting from the processing is transmitted to the connected BSC 275. The BSC 275 provides call resource allocation and mobility management functions, including the organization of soft handoffs between the base stations 270. The BSC 275 also transmits the received data to the MSC 280 and the MSC 280 provides additional transmission services for connection with the PSTN 290. [ Similarly, the PSTN 290 connects to the MSC 280, the MSC 280 connects to the BSCs 275, and the BSCs 275 communicate with the BSs 270 ).

5 is a flowchart illustrating an example of a method for enabling a user to easily select and execute a specific service related to a call in a state of a telephone conversation in a mobile terminal according to the present invention.

In the above, the telephone busy state includes a user talking with at least two parties (called parties).

A service capable of making a call with the plurality of parties includes a conference call service in which a telephone is connected to the second and third parties in turn during a call to make a call at the same time. In addition, when a call is received from another party during a call, there is a call waiting service that can selectively exchange the call party without disconnecting the call connection with all parties. In addition, there is a call hold service that allows a call to another party after a short wait without interrupting the call during the call, and then to talk to the first party again. In addition, there is a call connection service that connects the call to another party during a call such as an extension call.

Typically, the above-mentioned services selectively transmit a call button, a specific function button (e.g., *, #), a specific service code (e.g., 21) . The above-mentioned services are additional services provided by the telephone service provider. Users who wish to use the additional services must know how to use the services, which is inconvenient to use.

5, when the mobile terminal enters a busy state (S101), the controller 180 internally sets an additional service menu available in the busy state.

If a specific key (soft key or hardware key) for calling a menu included in the mobile terminal is input (S102), the control unit 180 determines whether a function menu available in the busy state, And displays the service menu on the display unit 151 (S103, S104).

The specific key for calling the menu may be set separately for the menu for function execution or the menu for executing the additional service. If a key for calling the supplementary service menu item or the supplementary service menu is input, the control unit 180 displays a list of available supplementary services (S105, S106).

The key for calling the menu may be implemented by a soft key or a button for receiving a touch input.

If a specific additional service item is selected in the displayed additional service list (S107), the controller 180 automatically inputs and executes information necessary for executing the corresponding supplementary service (S108). That is, at least one or more of the specific function button, a specific service code, a call button, and a counterpart telephone number are automatically input and executed in accordance with a specific sequence combined for execution of each additional service.

If there is information to be directly input by the user, the information input screen is displayed on the display unit 151 (S109). The information to be directly input by the user includes 'other phone number'. Also, even if the user does not call the 'phonebook' menu for inputting the phone number, the 'phone number search screen' can be automatically displayed.

The user can select a desired number of the other party's phone number through the phone number search screen without having to add the phone number one by one. When the confirmation key is input after the selection of the other party's phone number is completed, the controller 180 sequentially connects the selected party to the selected partner to execute the selected supplementary service (S110).

As described above, according to the present invention, even if the user does not know how to use the supplementary service or is unfamiliar with the supplementary service, the user can easily and simply use the supplementary service through the menu.

(Example 2)

Hereinafter, an alternative communication method using the plurality of counterpart-connected information will be described.

8 is a diagram for explaining a method of selectively making a call with a specific one of a plurality of callers in a mobile terminal according to the present invention. If it is assumed that a call service among three parties is used, Each time the call button of the user terminal is inputted, the base station alternately connects the other party to the user terminal, but does not display information of the other party in the current call. Thus, the user could not know exactly who he is currently speaking with.

Accordingly, the mobile terminal of the present invention displays the incoming call signal and displays the caller's information screen when another call is received during the call. At this time, it is possible to additionally display a guidance message on how to connect a new incoming call to the screen. In addition, the user can display a screen 410 on which the user can select a communication partner using the caller information included in the call incoming signal.

When the communication key 414 or the standby key 415 separately displayed for each communication partner displayed on the screen 410 is input, the control unit 180 can wait for the selected partner or make a call connection. It is possible to display each of the communication parties displayed on the screen by using icons 411 and 412 of a specific shape or color in a busy state or a standby state.

Also, the control unit 180 can directly switch the other party's call in the mobile station without requesting the base station to transfer the call. For example, in the case of the Internet phone system in which voice data is transmitted in a packet transmission mode, a plurality of parties can be simultaneously communicated through one transmission channel. Accordingly, the control unit 180 can switch the call or block the call to the specific party in a manner that does not transmit the voice packet, and can also transmit the content at the same time.

On the other hand, when it is assumed that a plurality of parties use the conference call service, the control unit 180 may be a specific type combining images, pictures, icons, outgoing phone numbers, or names, The screen 410 can be displayed.

The user can select one of the plurality of parties by touch or button input, temporarily wait for a call, and then transmit / receive private contents to / from another party. The message transmission function can be performed in a busy state.

(Example 3)

Hereinafter, a method for transmitting multimedia contents so that a party in a call waiting state is not tedious when making a telephone call with the plurality of parties will be described.

9 is a diagram for explaining a method of transmitting multimedia contents to a partner who is waiting for a call among a plurality of callers in the mobile terminal according to the present invention. As shown in the figure, when using a call service with a plurality of parties, the control unit 180 can display the information screen 511 about the phone connected party.

If the call waiting key 415 displayed separately for each communication partner displayed on the screen 511 is input, the control unit 180 blocks the voice transmission of the user and selects a predetermined multimedia content (for example, music, ) Can be automatically transmitted. If the call waiting is canceled, the transmission of the multimedia contents is stopped and the voice of the user is transmitted again.

When a multimedia content transmission key (for example, a moving image or a picture transmission key) 416 or 417 displayed separately for each communication partner displayed on the screen is inputted, the control unit 180 transmits predetermined multimedia contents (e.g., music, Video, image, and the like) or automatically display the multimedia content selection screen 520. FIG. If the multimedia content is selected, the controller 180 transmits the selected content to a pre-selected counterpart (or a counterpart in a call waiting state). A plurality of the multimedia contents can be selected and other contents can be automatically transmitted when the contents being transmitted are terminated.
