Problems solved by technology

However, if MS402 only obtains the private address of the MS that communicates IP messages with MS402, the address of the MS in the IP message can only be the private address of the MS. Since the private address of the MS is a valid address inside the ASN where the MS resides, Therefore, MS IP Proxy4011 will fail to forward IP packets because it cannot identify the private address of MS, which will affect the normal communication between MSs.

[0032] First, the first embodiment of the method of the present invention will be described with reference to FIG. 5A . The first embodiment of the method of the present invention is based on a WiMAX network architecture. The WiMAX network architecture includes a CSN and an ASN. Private addresses are used for communication between network nodes. The network nodes can be nodes such as mobile terminals or servers, as shown in FIG. 5A , A first embodiment of the method comprises the steps of:

[0033] Step S501A: Allocate a private address space for each ASN under the same CSN, and set an IP packet redirection unit in the ASN.

[0034] After allocating a private address space for each ASN, the private addresses of network nodes under the same ASN belong to the same private address space. In addition, one CSN can provide services for multiple ASNs. After allocating a private address space for each ASN, such Which ASN the MS is in can be determined through the private address of t...

Abstract

This invention provides one network point communication method based on Imax network rack, wherein, the network rack comprises connection servo network CSN and interface servo network ASN with private address for communication in between. The said communication method comprises the following steps: aligning each same CSN ASN each with private address space and setting IP message re-positioning unit in the ASN; the said IP message re-position unit determines IP message aim address with private address space to determine the transfer process. This invention also provides one interface servo network and Imax network rack structure.

Description

technical field [0001] The invention relates to WiMAX network technology, in particular to a communication method between network nodes based on the WiMAX network architecture, an access service network and the WiMAX network architecture. Background technique [0002] WiMAX (Worldwide Interoperability Microwave Access) mentioned in the IEEE802.16 standard is a wireless metropolitan area network (WMAN) technology, which proposes a new air interface standard for microwave and millimeter wave frequency bands. WiMAX is an emerging wireless communication technology used to transmit wireless signals. It can provide high-speed Internet-oriented connections. Using this technology, users can perform data communication at a very fast speed within a range of 50 kilometers. [0003] Founded on April 9, 2001, the WiMAX Forum is a non-profit organization jointly established by industry-leading new communication product and equipment companies. The organization will not only establish a s...
