Problems solved by technology

[0013] It can be seen that the current scheme has the following deficiencies by the above steps: when the mobile terminal MN is switched to different agent mobile management terminal PMAs, it needs to configure new routes through the DHCP protocol (the default gateway is the agent mobile management terminal PMA). It will undoubtedly increase the complexity and handover delay of the mobile terminal MN
[0017] The eth0 port of the router also receives the broadcast, but the router does not forward the broadcast by default, so the ARP request still cannot reach host B

Embodiment Construction

[0041] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. image 3 It shows a schematic diagram of the routing configuration process of the mobile terminal MN during the mobile handover process according to an embodiment of the present invention.

[0042] The access authentication technology uses the network access protocol PANA with identity authentication as an example, introduces the AAA system structure, and the mobile terminal MN uses DHCP to request an address.

[0043] Overall steps:

[0044] Step 1a, the mobile terminal MN establishes a link layer connection with the foreign agent through the PANA protocol, and starts the access authentication with the agent mobile management terminal PMA;

[0045] In step 1b, the AAA client (denoted as AAAc) process management module on the proxy mobile management terminal PMA exchanges AAA information with the AAA server (denoted as AAAs) process management ...

Abstract

The invention proposes a route collocation method applied to a mobile termination of PMIPv4, and proposes a scheme for the mobile termination to realize an absolute no participation in acting for switching mobile IP process through an adoption of agent ARP at the network end. Not needing to regulate network layout of a current wireless local area network and not needing any alteration or allocation on the current mobile termination, the scheme only needs to have a proper alteration of an agent mobile management end PMA of the network end to lower complexity and switching time lapse of the mobile termination.

Description

technical field [0001] The invention relates to a routing configuration method for a mobile terminal MN (Mobile Node) in Proxy Mobile IPv4 (Proxy Mobile IPv4, PMIPv4), and belongs to the field of network technology. Background technique [0002] The Mobile IP protocol (Mobile IP protocol) provides seamless handover mobility management for the mobile terminal MN, but it requires the mobile terminal MN to support the mobile IP function. If the mobile terminal does not support this function, the network side is required to provide mobility support. . Reference 1 [K.Leung, G Dommety, P.Yegani, K.Chowdhury, "WiMAX Forum / 3GPP2 Proxy Mobile IPv4", draft-leung-mip4-proxy-mode-07, work in progress, IETF draft, 2008.2] A network-based proxy mobile IPv4 solution is proposed, which introduces a proxy mobile management terminal (Proxy Mobile Agent, abbreviated as PMA), expands the function of a foreign agent (Foreign Agent, abbreviated as FA) in mobile IP, and replaces the mobile termin...
