| 20090168735 | STATION, SETTING INFORMATION MANAGING DEVICE, WIRELESS COMMUNICATION SYSTEM, SETTING INFORMATION OBTAINING METHOD, COMPUTER-READABLE MEDIUM - In a wireless communication system including a setting information managing device for managing setting information required for wireless communication, an access point, and a base station belonging to the access point for conducting wireless communication, the station belongs to the access point using connecting information for wireless connection to a setting network, connects via the access point to the managing device on the setting network, and obtains the setting information from the managing device. In this way, in the wireless communication system, the setting information required for wireless communication can be obtained by use of the connecting information for wireless connection to connect to the setting network. | 07-02-2009 |
| 20090240939 | SYSTEM AND METHOD FOR AUTHENTICATION IN WIRELESS NETWORKS BY MEANS OF ONE-TIME PASSWORDS - The present invention is directed to perform high-reliable authentication using a one-way function that a communication is a communication which was performed with the same apparatus to be authenticated by storing a password only in an apparatus to be authenticated (it is unnecessary to store a password in both of an authentication apparatus and an apparatus to be authenticated) without transmitting a challenge code. When a setting is updated in a setting management server, authentication is performed by using a one-time password obtained last time. A sound communication terminal performs a process using a hash function once on a one-time password transmitted this time, and performs authentication by determining whether the processed one-time password matches a one-time password obtained last time or not. Whether the information at the time of the change in the setting is proper or not is determined by a sound terminal. | 09-24-2009 |
| 20090318146 | SETTING INFORMATION REGISTRATION APPARATUS, WIRELESS COMMUNICATION SYSTEM, SETTING INFORMATION REGISTRATION METHOD, AND SETTING INFORMATION REGISTRATION PROGRAM - The present invention provides a setting information registration apparatus that can prevent unnecessary setting information from being generated, when setting information needed at the time of performing wireless communication is generated. A setting information registration apparatus ( | 12-24-2009 |
| 20100046416 | MOBILE IP CONTROL SYSTEM, MOBILE IP CONTROL METHOD, AND MOBILE IP CONTROL PROGRAM - To suppress communication delay and data loss caused by the radio type of a mobile terminal and the radio communication band when a communication packet is sent to the mobile terminal in a mobile IP system. A mobile IP control system includes: a radio base station ( | 02-25-2010 |
| 20100202350 | PROXY MOBILE IP SYSTEM, ACCESS GATEWAY AND METHOD FOR DETERMINING THE ORDER OF REGISTRATION NOTIFICATION MESSAGES USED THEREFOR - A proxy mobile IP system comprises: a mobile terminal including a time management/notification unit; the time management/notification unit alerting time information, managed by the mobile terminal itself, to an access gateway at the time of access authentication in proxy mobile IP (Internet Protocol) communication; the access gateway; the access gateway including a time information acquisition/management unit alerting the time information, received from the mobile terminal, to a mobility anchor, at the time of performing proxy mobile IP registration in the proxy mobile IP communication, as the time information received from the mobile terminal is carried on a registration notification message; and the mobility anchor; the mobility anchor including a time information acquisition/management unit alerting the registration notification message including the time information to a proxy mobile IP registration unit responsible for performing proxy mobile IP registration. | 08-12-2010 |
| 20100208657 | PROXY MOBILE IP SYSTEM, ACCESS GATEWAY AND METHOD FOR DETERMINING THE ORDER OF REGISTRATION NOTIFICATION MESSAGES USED THEREFOR - In a proxy mobile IP system, a mobility anchor comprises: a proxy mobile IP registration unit effectuating proxy mobile IP registration in proxy mobile IP (Internet Protocol) communication by one or more registration notification messages from an access gateway; and a last registration time recording/management unit effectuating recording and management of time of last registration by the registration notification message. The mobility anchor, on receipt of a new registration notification message, determines, in case a receipt time difference (or a receipt time interval) between the time of receipt of the new registration notification message and a registration notification message recorded last time in the last registration time recording/management unit is within a pre-set period of time, and the access gateway has changed by switching, possibility of order reversal of the new registration notification message and the registration notification message recorded last time. | 08-19-2010 |
| 20110228741 | METHOD AND SYSTEM OF UPDATING ROUTING/ESTABLISHING PATHS IN A HIERARCHICAL NETWORK - A mobile unit managing network is provided which is capable of supporting a communication area being wider than ever by one highest-layer router. A radio base station transfers a path updating notification fed from a mobile terminal to a lowest-layer router. The lowest-layer router establishes a path in which a network address to the mobile terminal exists in the radio base station and transfers path information to an intermediate-layer router serving as an upward router. The intermediate-layer router establishes a path in which the network address to the mobile terminal exists in the lowest-layer router and transfers path information to the highest-layer router. The highest-layer router, when having received path information notification from the intermediate-layer router, establishes a path in which the network address to the mobile terminal exists in the intermediate-layer router. | 09-22-2011 |
| 20110268036 | COMMUNICATION SYSTEM, TUNNEL MANAGEMENT SERVER, COMMUNICATION DEVICE, TUNNEL SETUP METHOD, AND PROGRAM - A communication system comprises a first communication device that transmits a setup request that causes a tunnel to be set up such that a first tunnel address of said first communication device and a second tunnel address of a second communication device are tunnel interfaces and a tunnel management server that receives said setup request from said first communication device and that, when said second communication device has a plurality of said second tunnel addresses, combines said plurality of second tunnel addresses and said first tunnel address and sets up a plurality of tunnels. | 11-03-2011 |
| 20110286332 | Flow control apparatus, network system, network control method, and program - A flow control apparatus that sends control information to one or more switching node apparatuses, where the control information is assigned to each series of communications performed between terminal devices via the switching node apparatuses. The flow control apparatus includes an effective time setting unit that sets an effective time of the control information based on an elapsed time measured from when the terminal devices which perform the series of communications start a communication via a specific one of the switching node apparatuses, in a manner such that the longer the elapsed time, the longer the effective time; and a sending unit that sends the control information every time when the effective time has elapsed. | 11-24-2011 |
| 20110310734 | COMMUNICATION SYSTEM, FLOW CONTROL DEVICE, FLOW TABLE UPDATING METHOD, AND PROGRAM - A communication system, wherein a switch node to which a terminal is connected can be recognized, and a flow table can be updated promptly in accordance with the status of the switch node. The communication system includes: a switch node that operates in accordance with a flow table in which processing content is defined for each of a plurality of flows, and a flow control device that includes a terminal management unit that records, based on a request to set a flow entry from the switch node, information of association between a terminal of a packet source and a switch node to which the terminal is connected, wherein the flow control device refers to the information of association to make the switch node execute a modification or deletion of a flow entry in the flow table. | 12-22-2011 |
