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： Disclosed is a technique for enabling a mobile terminal, which is capable of using a plurality of communication routes for communication with a correspondent node, to select an appropriate communication route to communicate with the correspondent node. According to the technique, the mobile terminal (UE/MN 313B) requests a predetermined network node (P-GW 317) to detect whether or not the correspondent node (CN 318B) exists in the same domain. The P-GW monitors a packet sent from the CN to the UE/MN and, when detecting the packet, determines whether or not the CN exists in the same domain. In the case of determining that the CN exists in the same domain, the P-GW reports information that the CN exists in the same domain, to the UE/MN. The UE/MN selects an interface used for communicating with the CN, based on the reported determination result.

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.

摘要： A technology is disclosed with which a mobile terminal moving in a PMIP domain receives various types of prefixes and selects a type of an address to be configured, and route optimization is performed without adding a signaling load on the PMIP domain. According to the technique, when connecting with a home domain, a MN (310) requests a plurality of prefixes. When a MAG (320) makes an AAA server (340) authorize the MN and receives a notification instruction of the plurality of prefixes from the AAA server, the MAG 320 makes a notification of the plurality of prefixes with a RA message (364), for example. The MN configures a plurality of addresses (for example, a PMIP address including a PMIP domain prefix or a global address including an on-link prefix) from the plurality of prefixes received and notifies the MAG of the same. The MAG registers a plurality of bindings relating to the plurality of addresses with a LMA (330).

摘要： Disclosed is a technique which enables a mobile node (MN) connected to a mobile router (MR) to carry out flow filtering in a mobile network. This technique allows an MN 25 in a mobile network 24 to set a policy needed for the flow filtering in an MR 10 and, in the present invention, an MR inserts an egress characteristic thereof into, for example, a router advertisement message so that the egress characteristic, a node in a mobile network cannot grasp originally, can be advertised to the interior of the mobile network. Thus, the MN can grasp a characteristic of an access network (characteristic of access system 20) even in a case in which it is connected to the MR, which achieves intelligent flow filtering.

摘要： A User Equipment (UE) that is simultaneously connected (via a 3G connection and a non-3G connection) to a Packet Data Network Gateway (P-GW) can direct how traffic flows would be routed from the P-GW to the UE. Typically, the P-GW would setup the 3G communication path to the UE when it receives a downlink data packet directed to the UE's 3G path. If the P-GW uses such logic for setting a communication path to the UE without knowing the user's actual intention, this might result in the case where the user would experience some service degradation for ongoing session. In addition, it is possible that the packets filters for a first UE interface are not utilized due to the erroneous setting of the packets filters for a second UE interface. To resolve this issue, the UE would indicate to the P-GW of the user's intention for communication path setup with the benefit of conserving the UE's battery.

摘要： A technology is disclosed for preventing packet and transferring packets to a switched interface with minimal delay, when a mobile node switches a using interface. According to the technology, when a MN 200 is communicating with a MAG (WLAN) 232, a PBU message 301 has already been transmitted from the MAG (WLAN) 232 to the LMA 220, and binding related to a WLAN connection 242 is already registered in the LMA 220. When an interface switching event 300 is generated, the MN 200 transmits to the MAG (WLAN) 232 via the WLAN connection 242, a binding in-advance registration message 302 for registering a binding in advance. When the MAG (WLAN) 232 detects disconnection 310 of the WLAN connection 242, the MAG (WLAN) 232 transmits a registration delete/trigger message 312a to the LMA 220, registers and triggers in the LMA 220 the in-advance registration binding registered in the MAG (WLAN) 232, and deletes the PBU message 301.

摘要： A technology is disclosed for reducing the burst of DAD messages which may be triggered due to the change of the network prefix when using the technique of the neighbor discovery proxy. According to this technology, in roaming from the access network link 101 to the access network link 102, MR 121 receives advertisement of a new prefix 172 from AR 112. MR 121 selects and informs, for example only MR 122, that it is necessary to change the prefix. Thus, MR 122 and VMN 132 configure new addresses, respectively. When address configuration is completed at the mobile network of MR 122, MR 121 informs another MR 123 that it is necessary to change the prefix, and then MR 123 and VMN 133 configure new addresses, respectively. This can prevent DAD messages generated along with the address configuration from flocking in a short period.
