Abstract: The present invention relates to an apparatus for a mobile device case, especially wherein a strap is attached to the rear of a mobile device case in a determined shape, so that a user securely supports a mobile device. To achieve this, there is provided the apparatus for a mobile device case which includes a case that covers at least one side of a mobile device in a circumferential direction to be coupled thereto, and a fixing means that is coupled to the case to fix a strap for supporting a user's fingers at two points on edges of the case.

Abstract: A method and an apparatus for managing power of a Wireless Local Area Network (WLAN) module in a portable terminal are provided. In the method, the WLAN module is operated according to a Power Save Mechanism (PSM). Whether the portable terminal operates in a sleep state is determined. At least one of a beacon interval and a Delivery Traffic Indication Map (DTIM) interval of the PSM is changed depending on whether the portable terminal operates in the sleep state.

Abstract: Provided is an apparatus and method for saving power in a dual mode portable terminal that concurrently supports a cellular network and an unlicensed band network. The method includes, upon disassociating from an in-association Access Point (AP) of an unlicensed band network, measuring a Received Signal Strength Indicator (RSSI) from the AP during a predetermined time and calculating an average value of the RSSI; and comparing the calculated average value with a predetermined threshold value and deciding whether to perform a mode conversion between a low power mode and a general mode.

Abstract: An apparatus and a method for processing high speed data using hybrid Direct Memory Access (DMA) are provided. The method includes determining a size of data to be transmitted, determining a memory access method of the data by comparing the determined size of the data with a first threshold, and determining an I/O bus access method of the data by comparing the determined size of the data with a second threshold.
