Problems solved by technology

[0033] The present invention provides a terminal switching method and system in WiMAX MIPv6, which is used to solve the problem in the prior art that when T-CoA is configured, the corresponding T-BS is not selected after the S-BS negotiates with the relevant network elements. The problem of burdening the system by needing to reconfigure its T-CoA address

Embodiment 1

[0100] After obtaining the S-BS and negotiating with the surrounding network elements, the MS knows the T-BS that can be handed over to, and then obtains the relevant information of the corresponding T-ASN from the S-ASN-GW. As shown in Figure 5, it is a schematic flow chart of embodiment 1, and it can be seen from the figure that it mainly includes the following steps:

[0101] S510. The S-BS periodically broadcasts a MOB_NBR-ADV message, which includes network identification information and characteristics of adjacent BSs. From it, the MS can acquire parameter information of neighbor cells related to handover. Once the MS finds a new BS, it will scan it.

[0102] S520, the MS requests the S-BS for handover through a MOB_MSHO-REQ message, and the message includes the BS ID that may participate in the handover.

[0103] At this time, the MS triggers the entire mobility procedure; if the network side triggers the mobility procedure, step S520 is omitted.

[0104] S530. After...

Embodiment 2

[0110] From the S-ASN-GW, the MS obtains all relevant configuration information of the target network corresponding to the BS that may be handed over to, temporarily does not perform T-CoA configuration, and stores the relevant information; until the S-BS negotiates with the surrounding network elements After the T-BS can be switched to, the T-CoA is configured by searching the relevant configuration information of the T-BS corresponding to the T-ASN in the above stored information, as shown in Figure 6, including:

[0111] S610. The S-BS periodically broadcasts a MOB_NBR-ADV message, which includes network identification information and characteristics of adjacent BSs. From it, the MS can acquire parameter information of neighbor cells related to handover. Once the MS finds a new BS, it will scan it.

[0112] S620. In order to analyze the found BSID (one or several), the MS sends RtSolPr to the S-ASN-GW, which contains the BSID to be analyzed; when the S-ASN-GW receives this...

Abstract

The disclosed terminal switch method in WiMAX MIPv6 comprises: A. SBS negotiates with relative element on the objective BS, and sends the objective BS mark to terminal; B. terminal obtains the configuration message of the objective access service network; C. terminal configures the objective transmit address; and D. SBS switches the terminal to objective BS. This avoids reconfiguring the transmit address when executing RtSolPr / PrRtAdv earlier than MOB_MSHO-REQ / MOB_BSHO-RSP and improves switch efficiency.

Description

technical field [0001] The present invention relates to the field of communication, in particular to 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). Currently, IPv6 h...
