Abstract: A method of forming a dielectric layer includes forming a preliminary dielectric layer on a substrate using a silicon precursor and performing an energy treatment on the preliminary dielectric layer to form a dielectric layer. In the dielectric layer, a ratio of Si—CH3 bonding unit to Si—O bonding unit ranges from 0.5 to 5.

Abstract: A method is used for setting a R-P link for data transmission/reception in a mobile communication system and for setting a R-P link between packet control function (PCF) and packet data serving node (PDSN) in a mobile communication system that connects a radio network with a packet network. The method first transmits a response request message from the PCF to identify the status of two or more PDSNs in the system, then measures the RTDs of those PDSNs responded to the response request message. The method subsequently prepares a list of PDSNs that satisfy a reference value among the measured RTDs and determines whether the subscriber's PDSN exists in the list of PDSNs. Finally, the method performs a R-P link setup using the prepared list of PDSN in accordance with a determined result.

Abstract: A system and method for controlling a data call traffic frame in a mobile communication system assigns a sequence number to the traffic frame transmitted and received between the SDU and the PCF. This allows for a lost traffic frame to be easily detected. Because lost traffic frames can be detected and re-transmitted between the SDU and PCF, the lost traffic frame can be restored without using a radio section. Thus, transmission reliability between the SDU and PCF can be improved and a waste of radio resources can be prevented.
