摘要： Disclosed is a technique to prevent the registration of false information that a mobile router is managing prefix information that is not actually managed. According to the technique, when a mobile network prefix is registered from an MR (mobile router 20) to a CN 30 (correspondent node), an HA (home agent) 10, for example, intervenes in signaling related to the registration to prevent the registration of false prefix information. For example, in process 150, the MR notifies the prefix information and the HA detects a test message 120 sent from the CN to the MR to check whether the prefix information used for the destination address is valid. If the prefix information is invalid, the packet is discarded.

摘要： Disclosed in a technique for more accurately checking a network condition such as a transmission delay generated in packet transmission between two nodes and other network conditions. A buffering node 10 is a network node having the function of transferring a packet. When a packet received by a network interface 11 is buffered in a cache 14, a buffer time processor 12 refers to an internal clock 13 to record the time of that moment (the buffered time). Then, when this packet is transferred, the buffer time processor refers again to the current time indicated by the internal clock and subtracts the buffered time from the current time to calculate a buffering time generated by a buffering delay in packet transmission. This buffering time is added to the packet and transmitted.

摘要： The present invention provides a technique to optimize communication route when two end nodes separated away from own home perform data communication with each other. According to this technique, a communication node (the initiator node 174) adds a predetermined destination option including own home address to a header of a packet to be transmitted to a correspondent node (LFN 151) under control of MR 141. HA 121 of MR copies a predetermined destination option and inserts it into a tunnel packet header when this packet is tunneled to MR. When the packet is transferred to the communication node under control, MR checks, by using the server, whether the predetermined destination option is inserted into the tunnel packet header or not. If it is inserted into the packet, a route optimization processing is started with the transmitter of the packet including the predetermined destination option with home address.
摘要翻译：本发明提供了一种当两个终端节点与自己的家庭分离时彼此进行数据通信的优化通信路由的技术。根据该技术，在MR 141的控制下，通信节点（发起方节点174）将包括自己的归属地址的预定目的地选项添加到要发送到对应节点（LFN 151）的分组的报头.MR 121的HA 121 复制预定的目的地选项，并且当该分组被隧道传送到MR时将其插入到隧道分组报头中。当分组被传送到控制下的通信节点时，MR通过使用服务器检查预定的目的地选项是否被插入到隧道分组报头中。如果插入到分组中，则使用包含具有归属地址的预定目的地选项的分组的发射机开始路由优化处理。

摘要： In order to verify if upper-level router information, or ULRI (information on the upper-level router with respect to a predetermined node) is valid, MN (Mobile Node) 220 associated to ULMR (Upper-Level Mobile Router) 210 acquires ULRI such as the address of ULMR (310), inserts ULRI into a BU (Binding Update) message, and sends it to HA (Home Agent) 235 (320). On receiving the BU message with ULRI, HA sends a BA (Binding Acknowledgement) message set to pass through the router that is specified in ULRI (330). If ULRI is valid, ULMR forwards the BA message to MN (340). If ULRI is not valid, ULMR discards the BA message.
摘要翻译：为了验证上级路由器信息或ULRI（相对于预定节点的上级路由器的信息）是否有效，与ULMR（上位移动路由器）210相关联的MN（移动节点）220获取ULRI 例如ULMR（310）的地址，将ULRI插入到BU（绑定更新）消息中，并将其发送到HA（归属代理）235（320）。在使用ULRI接收到BU消息时，HA发送BA（绑定确认）消息集，以通过ULRI（330）中指定的路由器。如果ULRI有效，则ULMR将BA消息转发到MN（340）。如果ULRI无效，ULMR将丢弃BA消息。

摘要： By introducing a hierarchical encryption scheme and the use of asymmetric cryptography, the critical information in message exchanges is concealed from unauthorized entities. This helps greatly in preventing man-in-the-middle attacks faced by inter-working. In addition, access control is conducted by introducing a network structure having a rule interpreter that is capable of mapping general rules to WLAN specific commands. It obviates the needs for mobile user's home network to understand information about every WLAN it is inter-worked with. A common interface independent of WLAN technologies could be used by the home network for all the WLANs. The above conception provides a solution to the problems of the protection of user identification information and access control in the inter-working of WLAN.

摘要： A technology is disclosed for reducing the number of encapsulations required when MAP forwards a packet to a mobile node which is layered within mobile networks, with mobile networks nested and multiple mobile routers chained behind MAP (Mobility Anchor Point). MAP 120 manages the binding information between RCoA and LCoA for each of lower-level nodes and grasps the prefixes of each of lower-level mobile routers, for example, the prefix of mobile network 104 of MR 140 or the prefix of mobile network 106 of MR 142. For example, MAP 120 informs MR 140 of the prefix of the mobile network 106 and the binding information between RCoA and LCoA. In this way, MR 140 can grasp a next forwarding destination of the packet transmitted from MAP 120 to MN 150, and the packet can be reached at MN 150 unless the packet is encapsulated multiple times.

摘要： When determining a quantization for digital audio signals having a spectral and temporal structure wherein the audio signals are buffered in frames and decomposed into spectral components, the method is: obtaining a variance and/or a representative of the components of the the frame within a defined frequency interval; computing a necessary bandwidth using psychoacoustic criteria; determining an initial quantization for each frequency interval using an approximate mathematical model; and iteratively increasing the quantization of each of the frequency intervals through a psychoacoustically weighted inverse relationship with the the variance of each of the frequency intervals.

摘要： The present invention introduces system, apparatus and method that reduce wastage of network resources and mobile phone resources. The mobile phone would indicate its status in a tracking area update message when it is connected to the device. The network can then understand from the status indication that the mobile phone is capable of delivering packets to the device, and would thus allow the server to initiate communications. An absence of the status indication would imply the mobile phone is not capable of delivering packets to the device, and the network would then disallow the server to initiate communications.

摘要： A technique is disclosed, according to which a mobile node, having a plurality of interfaces and performing communication according to flow information when an operator is performing communication based on the flow information as defined by a policy, can select an interface suitable for the flow and can perform communication. According to this technique, a mobile node (MN 10) having a plurality of interfaces has a list to indicate domain limited flows to be transmitted only within a specific network (a trusted network), and a list to indicate the trusted networks. When a certain interface performs handover, and in case there is a domain limited flow that uses the interface, it is decided whether the network of handover destination is a trusted network or not, and in case the network of the handover destination is not a trusted network, it is decided whether it is possible or not to transmit and receive the domain limited flow via another interface that is connected to the trusted network.

摘要： Disclosed is a technique capable of proper execution of access control based on various security policies set by a home user with regards to a packet sent from a visitor node. According to the technique, a MR (Mobile Router) 10 which manages a mobile PAN 30 determines whether a sender of a packet from a communication terminal connected to the mobile PAN is a home user's node which is allowed direct access into a home network or a visitor node (VN 31), and forwards the packet from the home user's node to an HA 20 while forwarding the packet from the visitor node to a policy server 36 located in a DMZ 35. This allows the policy server to perform access control on every packet from a visitor node which attempts to gain access into the home network based on a security policy 36a.
