Problems solved by technology

[0033] As described above, when the security association of the mobile terminal is established between the access router and the home agent, the home address of the mobile terminal for which the security association is established is transmitted from the access router to the home agent; but when the mobile terminal moves, and When the access router in which the agent function of the mobile terminal is set is changed, and the access router similarly performs the process of establishing a security association between the home agent and the access router, because the home address of the mobile terminal has been registered in the home agent to establish Therefore, the security association of the mobile terminal cannot be established in the target access router of the mobile terminal

Embodiment Construction

[0060] figure 2 is a view illustrating a specific embodiment of the mobile communication system according to the present invention.

[0061] like figure 2 As shown, according to a specific embodiment, two home agents 30a and 30b as management devices with home core networks 31a and 31b are configured; between the mobile terminal 10a and the mobile terminal 10b having mobile information managed by the home agent 30b. The mobile terminal 10a is located in the access network 21a, and the access router 20a as the first routing device has the access network, and the access network 21a is under the access router 20a; the mobile terminal 10b is located in the access network 21b, and access Router 20b supports the access network, and access network 21b is under access router 20b. Furthermore, the access network 21c is connected to the home agent 30a through the access router 20c as the second routing device. In this case, mobile terminals 10a and 10b have home addresses "HoA1" a...

Abstract

When a mobile terminal (10a) moves from an access network (21 a) to another access network (21 c), the unique information on destination of the mobile terminal (10a) in an access router (20c) is transferred as alternate information from an access router (20a) to a home agent (30a). The access router (20c) transfers the unique information on destination of the mobile terminal (10a) in the access router (20a) as original information to the home agent (30a) and at the same time transfers the unique information on destination of the mobile terminal (10a) in the access router (20c) as alternate information to the home agent (30a). Using these data, the home agent (30a) builds security association for the mobile terminal (10a) between the access router (20c) and the home agent (30a).

Description

technical field [0001] The present invention relates to a mobile communication control method, a mobile communication system, a routing device, a management device and a program, and more particularly to a mobile communication control method using IP (Internet Protocol) technology, a mobile communication system, a routing device, and a management device and program. Background technique [0002] With the development of current mobile communication technology, the standard of mobile IPv6 has been in the agenda of IETF (Internet Engineering Task Force). [0003] figure 1 is a view illustrating an example structure of a mobile IPv6-based conventional mobile communication system. [0004] like figure 1 As shown, in a conventional example, two home agents 130a and 130b having home core networks 131a and 131b respectively are provided, and communication based on transmission / reception of IP packets is performed between mobile terminal 110a and mobile terminal 110b, The mobile ...
