Abstract:
The present invention relates to a subscriber station security-related parameter negotiation method in a wireless portable Internet system. The subscriber station security-related parameter negotiation method includes security-related parameters in transmitting/receiving basic capability negotiation request messages and basic capability negotiation response messages such that the subscriber station and the base station negotiate the subscriber station security-related parameters. The security-related parameters include an authorization policy support subfield used to negotiate an authorization policy between the subscriber station and the base station, and message authentication code mode subfields used to negotiate a message authentication code mode. The base station can inform the subscriber station that authentication or message authentication is not performed and is omitted according to a service provider policy by writing it on the authorization policy support subfield or message authentication code mode subfield. In addition, the subscriber station and the base station can select an authorization policy formed with at least one combination through the authorization policy support subfield of the security negotiation parameters. According to the present invention, the service provider of the wireless portable Internet system can more efficiently and flexibly manage the system by providing a scheme for omitting an authentication function and a message authentication function as well as for supporting various authorization policies and message authentication functions.
Abstract:
A multiple mode multiple standby mobile terminal and self configuration method of the mobile terminal are provided for automatically configuring settings on multiple Subscriber Identity Module (SIM) cards. An identity module configuration method for a multiple mode multiple standby mobile terminal includes checking, when the mobile terminal powers on, reference identity information in the mobile terminal, determining whether identity information contained in an identity card attached to the mobile terminal is included in the reference identity information and establishing, when the identity information is included in the reference identity information, a connection to a communication network indicated by the identity information.
Abstract:
When an initial frame alignment during decoding of multi-frame data segments fails a cyclic parity check, a portion of the received data is retained and reused for a second decode attempt using a different frame alignment. For BCH data transmitted within a WCDMA system, the second of two frames received and failing a parity check on decode is retained and coupled with a third received frame for a second decode attempt. When incorrect frame alignment is the cause of failure of the first decode attempt, the correct frame alignment should be achieved using the second and third received frames. Recovery from initial incorrect frame alignment is thus quicker than systems discarding all data from the first decode attempt.

Abstract:
Disclosed is a laundry machine. The laundry machine has the entire side surface not implemented as a cover of stainless steel but implemented as a double structure of a side panel and a side cover of stainless steel that is attached onto the side panel. Thus, the laundry machine can have the excellent appearance by the side cover of stainless steel. And, it is capable of reducing the material cost by using the side panel for the interior. Further, since the side surface thereof is implemented as the double structure of the side panel and the side cover having different frequencies from each other, it is capable of absorbing and attenuating noise and vibration generated while the laundry machine is operated.

Abstract:
A phase change memory device and a method for manufacturing the same. The method includes the steps of defining bottom electrode contact holes by removing portions of an insulation layer, to expose bottom electrodes, on a semiconductor substrate on which the bottom electrodes and the insulation layer are sequentially formed; forming amorphous silicon spacers on inner sidewalls of the bottom electrode contact holes; and forming bottom electrode contacts in the bottom electrode contact holes.
Abstract:
A delay-locked loop circuit comprising a variable voltage generator and a delay-locked loop. The variable voltage generator is configured to generate a variable bias voltage signal in response to a standby signal. The variable bias voltage signal has differing voltage levels according to operation modes. The operation modes include a standby mode and an active mode. The delay-locked loop is configured to generate an internal clock signal in response to the standby signal and the variable bias voltage signal. The internal clock signal is synchronized with an external clock signal.
