Embodiment Construction

[0019] The composition and application of ideal embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] figure 2 It is a conceptual diagram of the wireless network of the present invention.

[0021] Such as figure 2 As shown, the foreign agent FA3 is constituted by one address, which is connected to each other, and the mobile node 4 will move to the above-mentioned linked areas for communication. One group in the foreign agent 3 is an area managed by the home agent 2, and the home agent 2 and other groups of home agents 2 are managed by a SIP server 5 connected through a SIP network.

[0022] The wireless network constituted as above can be applied not only to the public network, but also to the environment of the home network. Here, the so-called public network includes KT broadband and mobile communication network, etc.; the so-called home network refers to the environment connected by wireless connect...

Abstract

The invention discloses a cross-region switching supporting method for supplying continuous communication of wireless network, especially relating to the change of basic server region. Compared to the network cross-region switching method formed by several sub-network stations and communicated via the wireless, the invention comprises following steps: utilizing the conversation stored in the root server of said internet realm name to start the protocol server and managing the address information of mobile node; utilizing said address information, the mobile node can move between the sub-network stations via the cross-region switching method; and said mobile node utilizes the mobile IP and the software cross-region switching method to move inside the sub-network station. And the invention can realize the continuous communication of mobile node and reduce the cost of triangular route and network.

Description

【Technical field】 [0001] The present invention relates to wireless networks, and more particularly to handoff support methods for providing continuous communication when the Basic Service Area (BSA) changes. 【Background technique】 [0002] The wireless local area network (LAN) technology, which is being popularized rapidly recently, has been generally considered to be an important part of realizing home networks including public networks. Access to the user network through an ordinary AP (wireless access point, omitted below), and free communication can be performed within the AP's BSA (Basic Service Area: 'BSA' below the basic service area), but if you leave the area or enter other BSAs, Existing connections should be severed and reconnected with APs in the relevant area. [0003] In this case, there is a problem that continuous streaming or data service is impossible. [0004] There is a way to utilize mobile IP by supporting the general method of mobility of existing co...
