A method and an apparatus for a Mobile Station (MS) to select a network in a communication network are provided. The method includes searching for a first network, and searching for a second network that has a lower priority than the first network while searching for the first network.

Apparatus and method for selecting network in communication system

The present invention relates to a backlight image sensor chip having improved chip driving performance, in which a region other than a pad region, on which a conductive pad is formed, and a sensing region, on which an optical filter is formed, is used as a region for auxiliary driving so that additional functions such as auxiliary power supply, auxiliary signal transmission and auxiliary operation control can be performed, without additional process, in the backlight image sensor chip having a restricted area, thereby improving the chip driving performance.

Backlight image sensor chip having improved chip driving performance

A handoff method and apparatus for a terminal based on efficient set management. A pilot search rate for base stations of a neighbor set is increased, thereby preventing a failure to perform a necessary idle handoff or a failure to receive a paging message for a call connection. A terminal checks if it is in an idle state or in a traffic state, and measures the pilot energy of the BS of the active set and the pilot energy of a BS of the neighbor set with different pilot measurement patterns according to the checked state. The terminal measures the pilot of the BS of the active set and the pilots of at least one BS of the neighbor set while in the idle state. The terminal in the idle state operates in a sleep mode upon reception of information indicating that there is no paging channel, thereby minimizing its power consumption.

Handoff method and apparatus for terminal based on efficient set management in communication system

An apparatus and a method for receiving system information in a mobile communication terminal are provided. In the method, system information including scheduling information for at least one additional system information is received from a base station. Whether validity of the system information is determinable is determined. If it is determined that the validity of the system information is not determinable, system information including scheduling information for at least one additional system information is received again from the base station.

Apparatus and method for receiving system information in mobile communication terminal

A method and apparatus for receiving system information from a Base Station (BS) in a Mobile Station (MS) in a mobile communication system are provided, in which it is determined whether there is buffered system information in a buffer, if current system information has an error, it is determined whether a combining condition is satisfied, in the presence of the buffered system information, the combining condition being defined by at least one of a Master Information Block (MIB) value tag, a System Information Block (SIB) value tag, and modification time information that are associated with the current system information, and the current system information is combined with the buffered system information, if the combining condition is satisfied.
