摘要： PROBLEM TO BE SOLVED: To provide a mobile terminal and an inter-terminal packet communication method, which can reduce the forwarding delay time of data packets in a mobile IP communication network and its variation. SOLUTION: The mobile terminal provided with a mobile IP packet communication function and a communication route optimizing function has a session control part 373 which sets sessions between ends by session control messages of a protocol like SIP other than mobile IP. When the mobile terminal device receives a session control message 201 from the other party device in a communication network distant from a mobile IP home network, the session control part transmits a response 202 to the reception message after executing optimization 206 to 210 of communication routes to the other party device by the communication route optimizing function.

摘要： PROBLEM TO BE SOLVED: To comfortably utilize an Internet service on the Internet by attaining connection for a PHS(R) call without using the switch of a line exchange node. SOLUTION: When a PHS (R) subscriber (a) desires to receive the Internet service, the PHS (R) subscriber (a) originates a line exchange call and connects it to a PHS (R) base station (b). When the dial number of this PHS (R) subscriber (a) is a telephone number for Internet connection, the PHS (R) base station (b) does not connect the originated call of the PHS (R) subscriber (a) to the line exchange node but connects it to a gateway device (d). Then, this gateway device (d) authenticates the subscriber by accessing a service control node (f) to be utilized for a line exchange service. Further, the gateway device (d) connects the originated call of the PHS (R) subscriber (a) to an Internet server (e) by performing signal conversion and media conversion from a line exchange protocol to an Internet protocol.

摘要： PROBLEM TO BE SOLVED: To allow a mobile terminal in contact with an additional service other than a call transmission/reception service in a mobile network to receive the additional service at a mobile network at a roaming destination even when the mobile terminal moves (roams) to a service area of the other mobile network not serving the additional service. SOLUTION: In the case that a mobile terminal 11 in roaming with a B network 102 makes a call to request an additional service (e.g. extension number service) to a B network LS exchange 108, when the extension number service in the B network 102 is not available, the exchange 108 routes the call from the roaming mobile terminal 111 to an A network 101 to which the roaming mobile terminal 111 subscribes to allow the A network 101 being the routing destination to serve the requested extension number service.

摘要： PROBLEM TO BE SOLVED: To utilize an additional service on the Internet such as grasping of call origination from another subscriber who is not connected to the Internet or service start even during an Internet service connection. SOLUTION: When the other subscriber tries to call a subscriber (a) during the Internet service connection, a line exchange node (b) which receives a call from the other subscriber requests the transfer of the call from the other subscriber to a gateway device (c). The gateway device (c) performs signal conversion and media conversion, acquires the IP address of an Internet server on the basis of the telephone number of the subscriber (a) and instructs to an Internet server (d) an incoming call notice to which the IP address of the subscriber (a) is set. By using an Internet protocol, the Internet server (d) reports the presence of incoming notice from another subscriber to the subscriber (a).

摘要： PROBLEM TO BE SOLVED: To dissolve competition by updating the competing condition information of an exchange node by requesting offer of required additional service when service competition occurs in an exchange node, downloading competing condition information in accordance with the offer from a service control node. SOLUTION: When multi-person connection 900 is requested by a user a108 executing virtual exclusive line service during communication with a user b109, a service competition table 103 is indexed by a service executing part 104. The service is supposed to compete on the service competition table 103 and its cause is defined as absence of a charge adjustment scenario 209 in the case of transfer from the virtual exclusive line service to multi-person connection service here. The charge adjustment scenario 209 is added to the service control node and a service condition table 210 is rewritten in accordance with the addition. Transfer to the multi-person connection service is enabled during the virtual exclusive line service on the service competition list 103 by downloading a new service condition table 210 to the exchange node 100.

摘要： PURPOSE:To realize a compact and thin actuator by arranging an objective lens in a space side, which is made by a supporting member, and preventing another structure body from existing in a space between lens. CONSTITUTION:A pole 2 for fixing is fitted to a base 1 and a holder 3 is provided to this base to fix a supporting member 4. An objective lens 8 is provided in the upper side or inner side of a lens holder part 10, which is protruded to the space in the holder 3 side from a supporting center surface 7, at the tip of a bobbin 9, whose lower surface is plain structure. Then, the objective lens is mounted after the adjustment of parallelism. In a balance weight 15, the bobbin 9 is provided on the surface 7 as a center and out of the surface 7, the lens 8 and holder part 10 are determined so that a thetay direction revolving inertia moment can be equal to the central part in a Z-direction which is made by the midpoint of supporting members 4a and 4b. Then, the lens and holder part are also determined so that inertia moment distribution in a thetax direction of the midpoint.
