| 20090291685 | RADIO COMMUNICATION SYSTEM, COMMUNICATION DEVICE, AND RELAY DEVICE - Disclosed is a technique in which, when no reliability exists between a previous communication device and a destination communication device with respect to a mobile terminal, a context which is setting information needed for making a connection of the mobile terminal to a network is transferred at a high speed from the previous communication device to the destination communication device. According to this technique, before movement, a mobile terminal | 11-26-2009 |
| 20100040021 | COMMUNICATION METHOD, COMMUNICATION SYSTEM, MOBILE NODE, PROXY NODE, AND MANAGEMENT NODE - A technique of acquiring a binding ID when a mobile node performs handover is disclosed. According to the technique, when an MN | 02-18-2010 |
| 20100091703 | BINDING UPDATE METHOD, MOBILE TERMINAL, HOME AGENT, AND BINDING UPDATE SYSTEM - Disclosed in a technique for providing a binding update method and the like capable of resolving such a situation that a BA message keeps reciprocating between HAs. According to the technique, there is provided a binding update method, in which a mobile terminal transmits, to a home agent of the mobile terminal, a first message containing an address that is the destination to that the home agent forwards, and the home agent of the mobile terminal updates, based on the first message, a cache in which a home address of the mobile terminal is associated with an address that is the destination to that the home agent forwards, and transmits a second message as a reply to the first message to the mobile terminal, wherein when receiving the second message, the mobile terminal transmits, to the home agent of the mobile terminal, a third message notifying that the second message has been received, and after receiving the third message, the home agent of the mobile terminal updates the cache. | 04-15-2010 |
| 20100097991 | COMMUNICATION METHOD, COMMUNICATION SYSTEM, MOBILE COMMUNICATION DEVICE, AND DESTINATION PARTNER COMMUNICATION DEVICE - A technology is disclosed for performing route optimization on only a one-way direct route when communication is performed between a mobile node and a correspondent node on a direct route without passing through a home agent of the mobile node. In the technology, (1) the MN transmits a HoTi message to the CN via the HA, (2) the CN transmits a HoT message to the MN via the HA in response to the HoTi message, (3) the MN transmits a CoTiα message directly to the CN, (4) the CN authenticates the CoTiα message and transmits a CoTiα message to the MN via the HA, (5) the MN transmits a BUα message directly to the CN, and (6) the CN authenticates the BUα message and transmits a BAα message to the MN via the HA. | 04-22-2010 |
| 20100115109 | COMMUNICATION CONTINUING METHOD AND COMMUNICATION TERMINAL DEVICE USED IN THE METHOD - 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. | 05-06-2010 |
| 20100232503 | COMMUNICATION SYSTEM, COMMUNICATION METHOD, RADIO TERMINAL, RADIO RELAY DEVICE, AND CONTROL DEVICE - 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 UE | 09-16-2010 |
| 20100278112 | BINDING UPDATE METHOD AND MOBILE TERMINAL DEVICE USED FOR SAME - Disclosed is a technique for providing a binding updating method and the like, capable of reducing the number of messages, and hence the power consumption of terminals and processing time required for binding update between both terminals. According to the technique, a first mobile terminal sends a second mobile terminal a first pair of messages including predetermined information on the first mobile terminal to acquire predetermined information on the second terminal. The second mobile terminal sends the first mobile terminal a second pair of messages including the predetermined information on the second mobile terminal. The first mobile terminal sends a third message to which authentication information is added, the authentication information generated based on the predetermined information on the second mobile terminal. The second mobile terminal sends a fourth message including response information to the third message and to which authentication information is added, the authentication information generated based on the predetermined information on the first mobile terminal. When the authentication information from the first mobile terminal is valid, the second mobile terminal updates binding information, while when the authentication information from the second mobile terminal is valid, the first mobile terminal updates the binding information. | 11-04-2010 |
| 20100284306 | BINDING UPDATING METHOD AND MOBILE TERMINAL USED BY THE METHOD - Disclosed is a technique for providing a binding updating method and the like, capable of reducing the number of messages, and hence the power consumption of terminals and processing time required for binding update between terminals. According to the technique, the method includes the following steps: A predetermined mobile terminal sends a mobile terminal as the next destination first and second messages including predetermined information for each of other mobile terminals based on a predetermined order of message transmission. A mobile terminal that has received the first and second messages acquires predetermined information addressed to its own terminal, adds predetermined information for each of mobile terminals other than its own terminal to the first and second messages, and sends the first and second messages to a mobile terminal as the next destination based on the predetermined order of message transmission. A mobile terminal that has acquired all pieces of predetermined information addressed to its own terminal generates authentication information for each of the other mobile terminals based on the predetermined information, and creates and sends a third message including the authentication information for each of the other mobile terminals. A terminal that has received the third message updates binding information when the authentication information included in the third message is valid. | 11-11-2010 |
