Problems solved by technology

[0010] However, in the conventional mobile communication method described in the literature "Fast Handovers for Mobile IPv6" and IETF Mobile IP WG, since the source access router device and the transfer destination access router device exchange messages and establish a tunnel, Both access router devices must be compatible with high-speed mobile IP
That is, even if an access router device not compatible with high-speed mobile IP is instructed to establish a channel, it is ignored, resulting in packet loss
[0011] On the other hand, in the conventional mobile communication method described in Japanese Unexamined Patent Publication No. 2003-209890, even if both the access router devices of the source and destination of the transfer are compatible with high-speed mobile IP, the channel cannot necessarily be established, and the inefficient communication is performed. Forward
[0012] In the actual network, since not all access router devices are compatible with high-speed mobile IP, there is a problem that high-speed mobile IP cannot be applied
[0013] Furthermore, in the configuration of JP-A-2002-125254, since it is necessary to frequently perform buffering or bicast processing on the home agent device, there is a problem that the load on the home agent device increases

Embodiment 1

[0094] FIG. 1 is a block diagram of the mobile communication system of the present invention.

[0095] In FIG. 1, local networks 10 and 11 are networks connected to the Internet and constituted of a plurality of routers and hosts on which Internet protocols are installed. The mobile communication device 20 communicates using the Internet protocol, and is connected to the local network 10 through the access router devices 100a-100c or connected to the local network 11 through the access router devices 100d-100f. The communication target terminal 80 communicates with the mobile communication device 20, the home agent device 40 performs location management of the mobile communication device 20, and the access router information server device 60 stores the access router devices 100a-100c, 100d- 100f information. The communication target terminal 80 , the home agent device 40 and the access router information server device 60 are connected to the Internet 1 .

[0096] First, the ...

Embodiment 2

[0258] Fig. 35 is a diagram showing the structure of the mobile communication system in this embodiment, which is different from the mobile communication system in the first embodiment in that it has a buffer node (BN) 90 for temporarily storing data.

[0259] In addition, FIG. 36 is a diagram showing the configuration of the home agent device 70 in this embodiment.

[0260] In FIG. 36, the data forwarding unit 71 forwards the data addressed to the mobile communication device to be managed to the pre-registered buffer node 90, and the message generating unit 72 generates a buffer request message to instruct the buffer node 90 to store the transmitted data or to instruct the buffer node 90 to store the data. The forwarded buffered packets of the data send the Start message. This buffer request message is the same as the message shown in FIG. 24 . In addition, FIG. 39 shows the format of a buffered packet transmission start message.

[0261] In Fig. 39, by setting the value co...

Abstract

A mobile communication apparatus (20) comprises a mobile IP / high-speed mobile IP processing part (25); an access router searching part (28) for acquiring information related to access router apparatuses; a high-speed mobile IP compliance determining part (27) for determining whether the access router apparatuses comply with a high-speed mobile IP; and a high-speed mobile IP control part (26) for controlling the contents of a message produced by the mobile IP / high-speed mobile IP processing part (25). According to this, even if any of access router apparatuses does not comply with the high-speed mobile IP, the procedure of high-speed mobile IP can be implemented, thereby reducing packet loss.

Description

technical field [0001] The present invention relates to a mobile communication method using Mobile IP, a mobile communication device, a home agent device, an access router information server device, and a mobile communication system. Background technique [0002] The mobile communication system using Mobile IP consists of the following parts: a mobile communication device that communicates while the subnet moves, a home agent device that manages the location of the mobile communication device, and a communication partner connected to the Internet that communicates with the mobile communication device An access router device connected to a terminal or a mobile communication device to communicate with a communication partner terminal connected to the Internet. In such a configuration, as a conventional mobile communication method using mobile IP, there is a technology described in the document "MobilitySupport in IPv6" and IETF RFC3775. [0003] First, when the mobile communi...
