Embodiment approach 1

[0096] FIG. 1 is a diagram showing the configuration of a mobile network system according to Embodiment 1 of the present invention.

[0097] In FIG. 1, a mobile network 2 is constituted by mobile routers (MR) 4-1, 4-2 and terminals 5-1, 5-2. Also, in an external network (such as the Internet) 1 are connected a home agent 7 that manages the location of the mobile network, access routers (AR) 3-1 to 3-4 that make connections with the mobile network, and an external terminal 6 .

[0098] In addition, in this embodiment, there are two mobile routers, but it is not limited thereto. In addition, the access routers 3-1 to 3-4 have wireless or wired interfaces such as cellular and wireless LAN connectable to the mobile router, and the internal link connected to the mobile router may be either wired or wireless.

[0099] Next, the configuration of the mobile router of the present invention will be described with reference to the drawings.

Abstract

In the mobile network (2), when internal links connected by multiple mobile routers (4) are initially set with unique network identifiers, if the mobile router (4) is notified from other mobile routers (4) If different network identifiers are initially set, one of the network identifiers initially set by itself and notified is selected as the network identifier of the internal link connected to itself. And when the selected network identifier is the same as the initial setting, the mobile router (4) notifies the network identifier in the mobile network (2) and simultaneously registers it in the home agent (7). And at the same time, the mobile router (4) registers the advertised network identifier in the home agent (7) as the network identifier of the internal link connected to itself.

Description

technical field [0001] The invention relates to a network identifier sharing method for multiple mobile routers in the same mobile network to share one network identifier in a mobile network system composed of a terminal, a mobile router and a home agent. Background technique [0002] Conventionally, the IETF NEMO-WG has studied a technology for providing mobility of the entire network composed of mobile terminal groups and routers. [0003] NEMO (Network Mobility) described in "Network Mobility Basic Support Protocol" (rfc3963.txt) written by Vijay Devarapalli et al. The network constituted (hereinafter referred to as "mobile network") and the home agent (home agent) that manages the location of the mobile router realize the data reachability of the mobile network. [0004] In a mobile network system composed of such a mobile network and a home agent, one mobile network may include a plurality of mobile routers to connect to other networks via a plurality of connection poi...
