摘要:
Disclosed is a technique allowing a transmission-end of data and a message to confirm a destination address in a transmission request from a reception-end so as to prevent an attack by a transmission request from an unauthorized third person. According to the technique, (1) MN1 transmits a HoTI message to CN2 via HA3, (2) CN2 transmits a HoT message to MN1 via HA3 in response to the HoTI message, (3) MN1 generates CoA from Home Token in the HoT message, and transmits a CoTIβ including CoA to CN2, and (4) CN2 compares CoA in the CoTIβ message with CoA generated from Home Token in the Hot message transmitted to MN1.

Disclosed is a technique in which, when a plurality of packet routing paths exist, a sender of the packet selects an optimum packet length so as to use network resources effectively. According to the technique, when a plurality of routing paths like a network A (104) and a network B (105) exist for a packet transmitted from a data transmitting apparatus (103) to a data receiving apparatus (102) via a network relay apparatus (101), the network relay apparatus or the data receiving apparatus searches path MTU information of each path, and notifies the data transmitting apparatus of multipath MTU information including each search result. The data transmitting apparatus refers to this multipath MTU information to compare the plurality of paths about their path MTU information to decide a packet length suitable for the packet transmitted to the data receiving apparatus.

A technology is disclosed for providing a handover processing method, and an access point and a mobile terminal used in the method, in which the handover processing method can prevent processing of a HO in a layer 2 and an HO in a layer 3 from occurring at same time simultaneously, and shorten waiting time caused by the HO. The technology includes a step of providing, by the access point, strength information held by the access point itself, the strength information that is information whether to promote a handover processing in the layer 3 or not to promote the handover processing in the layer 3, and a step of receiving, by the mobile node, the provided strength information, deciding whether to perform the handover in the layer 3 based on the received strength information, and performing the handover processing in the layer 3 based on the decision.

A technology is disclosed for efficiently managing the peer relationship, and in particular for allowing to discover which of one or more communication links of the network entity is connected to another network entity having the same identifier. According to this technology, for example, the ID Controller (202) of the network entity (201) generates a quasi unique identifier for the network entity from all the physical address on its multiple interfaces. The peer relationship controller (203) verifies if the generated quasi unique identifier is overlapping with that of another network entity. The link control logic (205), upon sending a message to the network entity associated with the unique identifier, determines correspondence of the unique identifier with the peer network entity to interchangeably use the communication links (link 1 (211) to link n (213)).

A technique is disclosed, according to which it is possible to efficiently use network resources, to reduce the burden on a control device, and to control the communication between radio terminals by the control device when a transmitting side radio terminal and a receiving side radio terminal are connected to the same radio relay device. According to this technique, when a transmitting side UE1 and a receiving side UE2 are connected to the same E-Node B 103, the transmitting side UE1 divides a transmission packet addressed to UE2 into a first packet to be transmitted via a route not passing through ACGW 105 and a second packet to be transmitted via a route passing through ACGW 105, and the packets are transmitted to E-Node B 103. E-Node B 103 transmits the first packet to UE2 and also transmits the second packet to ACGW 105. ACGW 105 receives the second packet and transmits it to E-Node B 103. E-Node B 103 receives the second packet transmitted from ACGW 105 and transmits it to UE2. UE2 receives the first packet and the second packet and synthesizes them to restore the initial packet.

A technology is disclosed for providing a communication continuing method and the like that can shorten an amount of time required to complete message exchange for changing addresses of both ends of the SA, and efficiently perform the message exchange, without increasing the number of messages. In the technology, a step at which the second communication terminal sends the first message to the first communication terminal in accompaniment with movement of the second communication terminal itself is included, the first message requesting an update of an address in security information held by the first communication terminal. A step at which the first communication terminal sends the second message to an address of the second communication terminal before movement in accompaniment with movement of the first communication terminal itself, and sends the third message to an address of the second communication terminal after movement when the first message is received before a response to the second message is received is also included, the second message requesting an update of an address in security information held by the second communication terminal and the third message requesting an update of an address in the security information held by the second communication terminal.
