Problems solved by technology

[0006] The RFC only defines the method for the MN to obtain the home agent address information through the home agent discovery message after obtaining the care-of address. It does not clearly define the method for the MN to obtain its home agent address information when the home link is started. After the address, the MN needs to exchange more messages with the home link to obtain the address information of the home agent, which is not conducive to the handover speed of the MN

Embodiment Construction

[0037] The core of the method and system of the present invention are: when the DHCPv6 (Dynamic Host Configuration Protocol) server receives the request message of the MN (mobile node), it obtains the home agent information of the MN, and the DHCPv6 server carries the obtained home agent information in The request response message is transmitted to the MN.

[0038] The following further describes the technical solution provided by the present invention based on the core idea of ​​the present invention.

[0039] The method for obtaining MN home agent information, such as home agent address information, of the present invention can be applied to mobile IPv6 networks and NEMO respectively, and the MN of the present invention is in the process of obtaining MN home address, obtaining MN forwarding address, and obtaining status-independent information. Zhongdu can obtain MN home agent information at the same time.

[0040] In the following, taking the MN home agent information as the MN...

Abstract

This invention provides one method and system to get mobile point home agent information, wherein, DHCPv6 servo receives mobile point require to get mobile point home agent information and to load agent information to transmission mobile point. This invention can get home agent information when requiring relative information at mobile point and determines home linkage or outside linkage to get home agent information.

Description

Technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and system for acquiring home agent information of a mobile node. Background technique [0002] DHCP (Dynamic Host Configuration Protocol) provides a mechanism for the host to dynamically assign IP addresses and other configuration parameters. In a network where the location of the host changes frequently, DHCP is used to dynamically allocate and manage the host's IP address and related parameters. When a host joins the network, it can dynamically obtain parameters such as an IP address from the DHCP server in the network, and automatically establish a communication channel with other hosts. [0003] DHCP is divided into two versions, v4 (version 4) and v6 (version 6), which are used in IPv4 and IPv6 networks respectively. DHCPv6 includes stateful and stateless methods. The stateful method means that the terminal device obtains the IP address and other c...
