摘要： Provided are a method and a system for controlling access authentication in the process of a handover. The method of controlling access authentication in the process of handover of a mobile node in a network that consists of a core network and a plurality of access networks, the method comprising: when the mobile node initially accesses a first access network, performing access authentication of the mobile node and registering and managing the authentication information by using a user profile server, and searching for a host channel adaptor adjacent to the mobile node and transmitting identification, a profile, and authentication information of the mobile node to a network access server, in which the searched host channel adaptor is mounted, by using a mobility control server; when the mobile node moves to a second access network, performing a handover procedure and performing re-access authentication procedure by transferring authentication information regarding the handover to a network access server which is included in the second access network; and after performing the re-access authentication procedure, searching for a host channel adaptor adjacent to the mobile node and transmitting authentication information to a network access server which includes the searched host channel adaptor by using the mobility control server. Accordingly, an access delay time in the process of a handover can be reduced.

摘要： An optical disk drive adopting an optical disk as a recording medium is provided. The optical disk drive includes an adjusting mechanism on a deck to adjust phase and tilt. The adjusting mechanism includes a phase adjusting device which is installed on the deck, for supporting one end of at least one of first and second shafts to adjust the phase, and a complex adjusting device which is rotatably installed on the deck, for supporting the other end of the at least one shaft to adjust the tilt and phase. Therefore, the optical disk drive can store a large amount of information in a disk by a highly precise deck mechanism and be stably installed regardless of the installation direction and position thereof. Further, a tray can be ejected without electric power and simple and convenient assembling and maintenance thereof are guaranteed.
