Methods and apparatuses are provided for providing information at an electronic device. Incoming call entries and outgoing call entries corresponding to phone numbers are displayed. Based on receiving a selection of one of the call entries, a first option is displayed for modifying prestored contact information associated with the phone number corresponding to the call entry, without displaying a second option for adding the phone number to the address book, and call history information is displayed for the phone number, when the phone number is in the address book. The prestored contact information associated with the phone number includes a name for the phone number. The second option is displayed, without displaying the first option, and the call history information for the phone number is displayed, when the phone number is not in the address book.

Apparatus and method for providing incoming and outgoing call information in a mobile communication terminal

A electronic device and a control method of the electronic device are provided. A control method includes providing a first environment in which at least one application can operate and a second environment having an operation environment at least partially different from the first environment; determining whether a first application among the at least one application is to be executed in the second environment, when an execution command of the first application is acquired; and executing the first application in the second environment, when it is determined that the first application is to be executed in the second environment.

Electronic device for executing application and method of controlling same

An electronic device and method of controlling an electronic device are provided. The electronic device includes a communication module; a processor; and a memory that stores instructions to instruct the processor to install a first application operating only in a first environment, install a second application selectively operating in at least one of the first environment and a second environment, grant access to the first application to first data, the first data being generated while the second application operates in the first environment, deny access to the first application to second data, the second data being generated while the second application operates in the second environment, grant access to the second application to third data, the third data being generated while the first application operates in the first environment, and allocate the second application to at least the second environment without a user's input when the second application is installed.

Electronic device for installing application and method of controlling same

Methods and apparatuses are provided for providing information at an electronic device. Call history information for a phone number is displayed on a display of the electronic device. An option is displayed on the display of the electronic device. The option is either a first option for editing information associated with the phone number or a second option for adding the phone number to an address book based on whether the phone number is in the address book.

An apparatus and method for automatically registering and executing a preferred function in a mobile communication terminal. The method includes registering a function and a configuration value and use character string/numeral string value for the function, to a one-touch execution object. The method also includes, when a one-touch input for the one-touch execution object is sensed, executing the function registered to the one-touch execution object, by the configuration value and use character string/numeral string value registered to the one-touch execution object.

Apparatus and method for automatically registering and executing preferred function in a mobile communication terminal

Methods and apparatuses are provided for providing information. Phone numbers are stored in an address book in a memory of the terminal. Call history information for a phone number together with a first option for editing of information associated with the phone number are displayed on a display of the terminal, if the phone number is in the address book.

A method for providing a voice service in a Wireless Local Area Network (WLAN) is provided. The method includes, detecting a change in the total number of voice calls that are sent and received over a wireless channel of the WLAN, setting channel access-related parameters in the WLAN upon detecting the change in the total number of voice calls, and providing a voice service by applying the channel access-related parameters to the voice and data services.

Method and apparatus for providing voice service in wireless local area network

A method for transmitting a Voice over Internet Protocol (VoIP) by a wireless LAN Access Point (AP) in a communication system includes when a VoIP frame is input from a terminal, determining whether a buffer for eliminating a jitter generated in a wireless network is used, and storing the VoIP frame in a queue, determining whether the buffer is used, and when the buffer is used, determining a time interval for transmitting the VoIP frame stored in the queue and a service start time, and transmitting the VoIP frame stored in the queue in a wired fashion based on the determined time interval and service start time.

Method and apparatus for transmitting VOIP frame

Provided is a method for performing handover by a STAtion (STA) in a radio Local Access Network (LAN) communication system. The method includes sending a Network Controlled HandOver Setup Request Information Element (Ncho Setup Req IE) message indicating that the STA is to perform a scan operation using a controlled scan scheme, to a serving Access Point (AP); receiving a Network Controlled HandOver Setup Response Information Element (Ncho Setup Rsp IE) message including a scan parameter related to a controlled scan operation of the STA, from the serving AP; and broadcasting a probe request message to the serving AP and neighbor APs over channels according to the scan parameter included in the Ncho Setup Rsp IE message.

Apparatus and method for performing handover in radio local access network communication system

An apparatus and method for providing/receiving a voice service in a Wireless Local Access Network (WLAN) system. In the voice service provision method, an Access Point (AP) generates a multiplexing voice data packet by performing a multiplexing operation on at least two voice data packets among received voice data packets, and performs a multicast operation of multicasting the multiplexing voice data packet to Mobile Stations (MSs) which should receive the at least two voice data packets.

Method and apparatus for providing voice service in communication system

Methods and apparatuses are provided for providing information. Phone numbers are stored in an address book in a memory of the portable electronic device. Call history information for a phone number is displayed on a display of the portable electronic device together with a first option for editing of information associated with the phone number if the phone number is in the address book.

A method and apparatus perform channel scanning in a wireless communication system. A signal intensity of an Access Point (AP) is compared with a scanning threshold, when the AP signal intensity not less than the scanning threshold, a channel scanning schedule list is generated in consideration of a scan time based on a passive channel scan scheme and a scan time based on an active channel scan scheme. The channel scanning is performed every channel scanning time, according to the channel scanning schedule list.

Method and apparatus for channel scanning in a wireless communication system

A method and a mobile communication device are provided for providing information. Phone numbers in an address book are stored in a memory of the mobile communication device. A display unit of the mobile communication device displays call history information for a phone number. It is determined whether the phone number is in the address book. A menu is displayed on the display unit, the menu having either a first option for editing information associated with the phone number or a second option for adding the phone number to the address book based on whether the phone number is in the address book.

Disclosed is a method for providing multiple formats through an XML based EPG schema in terrestrial DMB system. The method includes the steps of setting a predetermined type in an area for defining type information of the EPG information, setting the defined predetermined type to have at least one format value, and making a definition to convert a format type to the defined predetermined type in an XML schema for expressing the EPG service information.
