Communication method for network nodes, access service network and WiMAX network architecture

Abstract

An embodiment of the present invention provides a communication method between network nodes based on a WiMAX network architecture. The WiMAX network architecture includes a connection service network (CSN) and an access service network (ASN). Private addresses are used for communication between network nodes. The communication The method includes: assigning a private address space for each ASN under the same CSN, and setting an IP message redirection unit in the ASN; the IP message redirection unit determines the private address space where the destination address of the IP message is located, And forward the IP packet according to the determined result. The embodiment of the present invention also provides an access service network and a WiMAX network architecture.

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...

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.
