Abstract: A pore-filled ion exchange polyelectrolyte composite membrane from which the surface ion exchange polyelectrolyte has been removed and a method of manufacturing the same are provided. The ion exchange polyelectrolyte composite membrane exhibits low film resistance and low in-plane-direction swelling degree, and has a smaller film-thickness than a commercial film, and thus, can be used for various purposes. In addition, since the pore-filled ion exchange polyelectrolyte composite membrane is continuously manufactured through a roll-to-roll process, the manufacturing process is simple, and manufacturing costs can be greatly reduced.

Abstract: The present application relates to a method of generating a downlink frame. The method of generating the downlink frame includes: generating a first short sequence and a second short sequence indicating cell group information; generating a first scrambling sequence and a second scrambling sequence determined by the primary synchronization signal; generating a third scrambling sequence determined by the first short sequence and a fourth scrambling sequence determined by the second short sequence; scrambling the short sequences with the respective scrambling sequences; and mapping the secondary synchronization signal that includes the first short sequence scrambled with the first scrambling sequence, the second short sequence scrambled with the second scrambling sequence and the third scrambling sequence, the second short sequence scrambled with the first scrambling sequence and the first short sequence scrambled by the second scrambling sequence and the fourth scrambling sequence to a frequency domain.

Abstract: Provided is a data transmission system using a carrier aggregation. The data transmission system may assign a radio resource based on a correspondence relationship between a downlink and an uplink, and may transmit data using the assigned radio resource.

Abstract: A message transmitting method using a short message service (SMS) that can successively transmit messages that a mobile terminal user intends to transmit. According to the long message transmitting method using the SMS, in case that the message to be transmitted exceeds a predetermined length, identifiers representing a boundary of each predetermined unit of the message and an identifier representing that the message is divided and transmitted are inserted into the units of the message, and the message is divided and transmitted according to the inserted identifiers.

Abstract: A method for providing a broadcasting-type short message in a radio communication system includes receiving a broadcasting-type short message, checking whether a password of a terminal manufacturing company exists in the received short message, and restoring the short message in the terminal if the password of the terminal manufacturing company exists. Preferably, the password is included in a first byte of the short message regardless of the length of the short message. If the password is included in the message, the terminal includes a display for displaying all or a portion of the information in the message. Through the use of this password, only terminals of the manufacturing company which sent the short message will be able to gain access the message. Terminals made by other manufacturing companies will be restricted from this access.

Abstract: Disclosed is a method for measuring the number of service packets transmitted and/or received by a mobile handset, in which information for data service amount is provided to a data service user through the mobile handset. As a result, the user can estimate charges for mobile communication data services as they are accrued, thus allowing the user to manage cost and use the mobile data service capability more efficiently.
