Problems solved by technology

[0010] Five, the care-of address may be a port of the foreign agent 15 or the mobile node 13 (in this case, when the mobile node 13 moves to the foreign link 17, there is no foreign agent 15 in the middle), and the data packet is extracted from the tunnel at the care-of address out to mobile node 13
This also caused issues causing the R3 movement mode to be notified repeatedly

Embodiment Construction

[0070] The basic principle of the present invention is to add a step of making the WiMAX network determine that the mobile mode of the terminal R3 is the Proxy Mobile IPv4 or Client Mobile IPv4 mode during the terminal connection establishment process under the WiMAX network environment. To distinguish between two types of connections, to distinguish between the two types of connections, to ensure that the foreign agent does not repeat or mistakenly send network functions The entity notifies the functionality of the terminal's R3 mobility mode.

[0071] Under the same idea, the present invention can use two methods to judge the R3 mobile mode of the terminal, one is to make different marks or distinguish terminal connections in a single mobile mode, so that the foreign agent knows which R3 mobile mode the connected party belongs to, The present invention enumerates several implementation modes to introduce the idea of ​​the present invention in detail; the other is to eradicat...

Abstract

The disclosed method for notifying the terminal R3 mobile mode in WiMAX network comprises: deciding whether to notify the terminal R3 mobile mode by external proxy according to IPv4 register message, and setting Proxy Mobile IPv4 mode; adding mark into the mobile IPv4 register message from mobile IP proxy agent to external proxy; when the external proxy decides the mark indication as terminal access on Proxy Mobile IPv4 mode, do not notify the R3 mobile mode; or lese, notifying the R3 mobile mode as Client Mobile IPv4. This invention can avoid repeated or wrong notifying the R3 mobile mode to the network function entity from external proxy.

Description

technical field [0001] The present invention relates to an application method of a WiMAX (Worldwide Interoperability for Microwave Access, global access microwave interoperability) network, in particular to a method for notifying the WiMAX network of a mobile mode of a terminal R3. Background technique [0002] WiMAX is a wireless metropolitan area network technology based on the IEEE 802.16 standard, and its wireless side of the network is designed based on the wireless metropolitan area network access technology of the IEEE 802.16d / e standard. Now it mainly follows the IEEE 802.16-2004 (802.16d) standard formulated in July 2004. IEEE 802.16-2004 (802.16d) standard operating frequency band is 2GHz to 11GHz, which is a mixed frequency band of authorized and unlicensed. WiMAX adopts the physical layer of OFDM and OFDMA, which can effectively resist multipath fading. In the case of optimal channel fading, the transmission rate can approach 75Mbps. The IEEE 802.16-2004 (802....
