    • A method and an apparatus select a domain of an application server in order to support a voice call continuity service in a mobile communication system including an IP Multimedia Subsystem (IMS) domain and a Circuit Switched (CS) domain. The method includes selecting either the IMS domain or the CS domain according to a dynamic domain selection priority which is predetermined corresponding to a terminal when a voice call for the terminal is received. The method also includes anchoring the received voice call corresponding to the terminal through the selected domain. A voice call establishment for a terminal using first the most recent domain which is used for a voice call in a mobile communication system is initiated. Thus, it is possible in a mobile communication system to increase the domain selecting completion rates for a voice call service corresponding to a terminal.
    • 一种方法和装置选择应用服务器的域,以支持包括IP多媒体子系统(IMS)域和电路交换(CS)域的移动通信系统中的语音呼叫连续性服务。 该方法包括:当接收到终端的语音呼叫时,根据与终端对应的动态域选择优先级来选择IMS域或CS域。 该方法还包括通过所选择的域锚定对应于终端的接收到的语音呼叫。 首先启动用于移动通信系统中用于语音呼叫的最新域的终端的语音呼叫建立。 因此,可以在移动通信系统中增加对应于终端的语音呼叫服务的域选择完成率。

    • There is provided a method for preparing a natural cellulose-OAg matrix having antimicrobial activity without leaching silver from the cellulose-OAg matrix. The method comprises: introducing silver ions (Ag+) into a natural cellulose matrix by dipping the natural cellulose matrix in an AgCl-dissolved NH4OH solution; and substituting hydrogen (H) of hydroxyl group (—OH) in natural cellulose with Ag+ by drying the silver ion-infused natural cellulose matrix, thus to form a natural cotton-OAg complex. The cellulose-OAg matrix prepared in the method may be useful to continuously maintain antimicrobial activity by maintaining an effective concentration of silver, which does not have cytotoxicity to human skin, and chemically bonded silver is not leached during the rehydration due to the chemical bond between the silver and the cellulose matrix.
    • 提供了一种制备具有抗菌活性而不从纤维素-OAg基质浸出银的天然纤维素-OAg基质的方法。 该方法包括:通过将天然纤维素基质浸入AgCl溶解的NH 4 OH溶液中,将银离子(Ag +)引入天然纤维素基质中; 并通过干燥银离子注入的天然纤维素基质用Ag +取代天然纤维素中的羟基(-OH),从而形成天然棉-OAg复合物。 在该方法中制备的纤维素-OAg基质可以用于通过保持对人皮肤没有细胞毒性的银的有效浓度来连续地保持抗微生物活性,并且化学键合的银在再水化过程中不会被浸出,这是由于化学键 银和纤维素基质。
