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 wireless communication system in which a terminal according to an embodiment of the present invention can operate 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), in particular Long Term Evolution (LTE), Global System for Mobile Communications (GSM) However, the present invention is applicable to all communication systems including a CDMA wireless communication system.

[ 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. The 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.

In addition, FIG. 4 illustrates several Global Positioning System ('GPS') satellites 300. The satellites 300 help to locate at least one of the plurality of terminals 100. Although two satellites are shown in Figure 4, useful location information may be obtained by two or more satellites. The location information module 115 shown in FIG. 1 cooperates with satellites 300 to obtain desired location information. Here, you can track your location using all of the technologies that can track your location, as well as your GPS tracking technology. 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 reverse link signals 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 ).

Generally, a wireless headset can be connected to a communication terminal according to various functions. For example, a headset that can be connected to a terminal according to bluetooth can transmit voice of a call in a mono type or transmit / receive in stereo type according to HSP (Headset Profile) or HFP (Hands Free Profile) The headset can receive streaming music from the terminal by using the A2DP (Advanced Audio Distribution Profile) function, and the wireless headset and the terminal can receive AVRCP (Audio / Video Remote Control Profile) function.

In order to facilitate the explanation, the first headset is a headset capable of only making a call through the terminal, the second headset is a headset capable of talking via the terminal according to the call function or receiving music from the terminal according to the music play function, Is defined as a headset capable of receiving only music from a terminal according to a music play function.

The controller 180 of the terminal may control the local communication module 114 so that communication contents are not shared according to communication contents when communicating with a plurality of headsets. In the case of controlling the communication contents not to be shared, the display unit 151 can display the menu for the connection function through the UI. The controller 180 of the terminal can obtain information on the function of the wireless headset that tries to connect through the short distance communication module 114 from the headset. For example, when the terminal's local area communication module 114 is synchronized with the headset, the local area communication module 114 queries the wireless headset for information about a function for the wireless headset, for example, a call function or a music play function, A signal value including a response to the signal value can be obtained. If the function of the terminal corresponding to the function of the wireless headset connected according to the service value is the call function, the control unit 180 of the terminal waits for the call function of the terminal for the wireless headset. For example, a wireless headset can perform both a call function and a music play function, and the terminal waits to support a call function to the wireless headset even if only the current music play function is available.

When the short range communication module 114 receives the function information for the wireless headset, the controller 180 outputs the information to the controller 180. When the plurality of wireless headsets are connected to the terminal, Can be controlled.

5 to 14 are diagrams showing examples of screens in which a communication terminal and a menu according to a situation in which two wireless headsets are connected, respectively, according to an embodiment of the present invention. The communication method of the present invention will be described with reference to FIGS. 5 to 14 (a person skilled in the art can understand the present embodiment by extending the following example even if two or more wireless headsets are connected).

It is assumed in FIG. 5 that two wireless headsets connected to the communication terminal are all headsets capable of only a call function.

An example will be described in which the first device 1 is a headset capable of only a call function (first headset) and the second device (device 2) is also a headset first headset capable of only a call function. The control unit of the terminal can acquire the function information from each wireless headset after being synchronized with the wireless headset, respectively, for the functions of the first device and the second device.

The control unit controls the first device to be connected to the terminal and to display through the display unit of the terminal that the first device is performing the call function. If the second device is close to the terminal and the call is possible, the control unit of the terminal controls not to display a menu (e.g., a connect menu) that can connect the second device (menu 2) on the menu (c ). That is, the example of FIG. 5 does not display the [Connect] menu with the second device in the [Option] menu, but does not display the search (the menu to connect to another device ), Delete (stop the connection to the currently selected device), and delete all (stop the connection to all devices currently connected). Therefore, when the control unit of the terminal communicates with the first device, the second device can be controlled not to be connected to the communication terminal at the same time.

In the example of FIG. 6, it is assumed that the first device (device 1) of the two wireless headsets connected to the communication terminal is a wireless headset capable of only a call function and the second device (device 2) is a headset capable of a music play function and a call function .

(a) is a display screen of a menu in which an option (indicated by shading on device 1) is located in the first device so that the first device can be selected, (b) While performing the call function, the choices represent menus located on the second device, respectively. Since the second device is capable of both the call function and the music play function, if the second device is connected to the terminal simultaneously with the first device, the contents of the call for the person calling through the terminal using the first device can be transmitted to the user Can be provided. Accordingly, the controller of the terminal according to the present embodiment may be configured such that the menu item [connect], which is a menu for allowing the second device to be connected to the [option] menu, which is located on the second device, Can be displayed. However, even if the terminal is connected to the second device by selecting the [connect] menu as shown in (d), the terminal can transmit only the audio information according to the music play function to the wireless headset as the second device. That is, even if the function of the second device includes a call function and a music play function, the controller of the terminal can perform only the music play function with the second device since the terminal has already performed the call function with the first device. The display unit of the terminal can display the connection status as shown in FIG. 6 (d) even if only the music play function is supported by the second device.

In the example of FIG. 7, the first device (device 1) of the two wireless headsets connected to the communication terminal is a wireless headset capable of only the call function, and the second device assumes that only the music play function is the headset.
