A method for using a mobile switching center (MSC) having a large capacity, particularly a method for using a MSC such that many service providers can use the MSC in common, comprises confirming a caller group to which a corresponding caller belongs by checking a number when a call is initiated from the caller, receiving a called number, authenticating and authorizing the caller, and processing the caller and the call according to the caller group to which the caller belongs. When the authentication and authorization succeed, the process searches for a predefined greeting announcement for the particular caller group and, if one is found, connects the predefined greeting announcement to the caller. The process also determines according to the caller group whether a certain trunk should be used and, if so, connects the call to that trunk. If the authentication failed or authorization is denied caller, the method determines a authentication failed/authorization denied subscriber processing procedure corresponding to the caller group, and carrying out an operation according to the processing procedure. Also, the process may determine a charging format and desired statistical item(s) according to the corresponding caller group if a caller belongs to a caller group which desires to use a certain charging format and/or a statistical item(s).

An external memory access device and a method of accessing an external memory are provided. The external memory access device includes an internal memory unit for storing authentication information of at least one external memory and a control unit for extracting the authentication information from the internal memory unit, transmitting the authentication information to an installed external memory, and controlling to display accessibility of the external memory according to the result of a comparison between the stored authentication information and the authentication information of the external memory. Accordingly, a data security function is provided by setting a password to an external memory and enabling an access to the external memory in an authenticated terminal, and convenient access to the external memory is provided by managing a password and an automatic password decrypting function of the corresponding external memory in the terminal without requiring repeated input of the password.

A multi-layer insulation system for electrical conductors, an insulated electrical conductor, a process for preparing an insulated conductor, and an insulated conductor prepared by such a process are provided. The insulated electrical conductors are lightweight, qualify for temperature ratings of up to approximately 230° C., and demonstrate mechanical durability and hydrolysis resistance. As such, these insulated conductors are particularly useful for aircraft wire and cable.

Polyamide coating compositions that demonstrate strength and toughness, flame and corrosion resistance and resistance to hydrolysis and thermal degradation at coating thicknesses of less than or equal to 0.25 mm or 0.15 mm are provided. Such coating compositions are extremely useful for coating wires or cables that are housed in automotive electrical harnesses.

A nonvolatile memory device and a method of manufacturing the same are provided. An insulation layer having a high etching rate as compared with a pad oxide layer is formed as a buffer layer between a first STI film formed as a lower part of semiconductor substrate and a second STI film formed as an upper part of the semiconductor substrate, to obtain a pillar CD for an SAP structure. The buffer layer is etched more speedily in comparison with the pad oxide layer in a procedure of etching the pad oxide layer, thus ensuring a sufficient pillar CD without an excessive wet etch-back. Accordingly, a defect occurrence such as a grooving or seam can be prevented in realizing the SAP structure, and a tunnel oxide layer can be formed with uniform thickness.
