Embodiment 1

[0108] Embodiment 1 is a pure Stateful mode, and the MS acquires the T-CoA address itself and configuration information in the target network through DHCP.

Embodiment 2

[0109] Embodiment 2: as Figure 6 shown, including the following steps:

[0110] S601. The MS discovers a new BS and its BS ID through a link layer mechanism, and selects a possible BS to be handed over to at the same time.

[0111] S602. The MS sends an RtSolPr message (including the T-BS ID) to the S-ASN-GW, requesting it to issue relevant information (such as link layer address, link prefix, etc.).

[0112] S603. After receiving the message, the S-ASN-GW sends the relevant information of the subnet under the jurisdiction of the T-ASN-GW corresponding to the T-BS ID in a PrRtAdv message to the MS.

[0113] If the MS receives the PrRtAdv, it finds that the T-BS and S-BS selected by it are located in the same subnet, that is to say, the corresponding ASN-GWs of the two are the same (or the chain of the corresponding two ASN-GWs governing subnets S-CoA can continue to be used without obtaining T-CoA-related information.

[0114] S604, the MS uses the link prefix in the targ...

Abstract

The related terminal switch method in WiMAX MIPv6 comprises: A. terminal obtains the relative target access service network gateway sub-network configuration message according to target BS mark; B. terminal obtains target transmitting address and relative configuration message according to former obtained configuration message; and C. terminal executes the switch. This invention enriches the means for obtaining target network transmitting address, and benefits to fast switch in WiMAX system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal and a terminal switching method and system in WiMAX MIPv6. Background technique [0002] Although the Internet with Internet Protocol version 4 (IPv4 IP version 4) as its core technology has achieved great success, the further development of IP technology applications is directly limited due to the shortage of IPv4 address resources. However, with the rapid development of mobile and broadband technology, the demand for IP addresses is increasing rapidly. Although classless inter-domain routing (CIDR Classless Inter Domain Routing), network address translation (NAT Net Address Translation), hybrid addresses, but they only provide temporary relief from the strain on IPv4 addresses. In the 1990s, the Internet Engineering Task Force (IETF Internet Engineering Task Force) proposed the next-generation Internet protocol—Internet Protocol Version 6 (IPv6 IP version 6). Curre...
