example 1

[0097] Example 1: G-RS acts as the NAS of the G-Host (that is, the G-RS independently acts as the gateway of the G-Host), and the V-NSP and H-NSP of the G-Host and G-RS are merged. See Figure 8,

[0098] In this example, G-Host consists of PKMv2 Supplicant, CMIP Client, and DHCP Client. Among them, PKMv2 Supplicant is a mandatory function, and CMIP Client and DHCP Client are optional functions.

[0099] G-RS consists of PKMv2 Supplicant, PKMv2 Authenticator / AAA Client, CMIPClient / NEMO Client and DHCP Client.

[0100] Among them, PKMv2 Supplicant and PKMv2 Authenticator / AAA Client are mandatory functions, and CMIP Client / NEMO Client and DHCP Client are optional functions.

[0101] ASN must increase AAA Proxy (proxy) function.

[0102] As shown in Figure 8, the main functions of the architecture of this example are as follows:

[0103] 1. Establish a trust relationship between PKMv2 Supplicant of G-RS, Authentication Relay of ASN, PKMv2Authenticator / AAA Client of ASN, AAA Se...

example 2

[0112] Example 2: G-RS and ASN serve as the logical gateway of G-Host, and V-NSP and H-NSP of G-Host and G-RS are combined. See Figure 9,

[0113] In this example, G-Host is the same as Example 1, and consists of PKMv2 Supplicant, CMIP Client and DHCP Client. Among them, PKMv2 Supplicant is a mandatory function, and CMIP Client and DHCP Client are optional functions.

[0114] G-RS consists of PKMv2 Supplicant, Authentication Relay, CMIP Client / NEMO Client and DHCP Client. Among them, PKMv2 Supplicant and Authentication Relay are mandatory functions, and CMIP Client / NEMO Client and DHCP Client are optional functions.

[0115] ASN does not need to increase the AAA Proxy (proxy) function.

[0116] As shown in Figure 9, the main functions of the architecture of this example are as follows:

[0117] 1, 3 to 7 are the same as example one;

[0118] 2. Establish trust between PKMv2 Supplicant of G-Host, Authentication Relay of G-RS, Authentication Relay of ASN, PKMv2 Authenticato...

example 3

[0120] Example 3: G-RS acts as the NAS of G-Host, supports hierarchical mobile IP HMIP, and the V-NSP and H-NSP of G-Host and G-RS are merged. See Figure 10,

[0121] In this example, G-Host consists of PKMv2 Supplicant, CMIP Client and DHCP Client. Among them, PKMv2 Supplicant is a mandatory function, and CMIP Client and DHCP Client are optional functions.

[0122] G-RS consists of PKMv2 Supplicant, PKMv2 Authenticator / AAA Client, PMIP Client, FA, CMIP Client and DHCP Client. Among them, PKMv2 Supplicant and PKMv2Authenticator / AAA Client are mandatory functions, and PMIP Client, FA, CMIP Client and DHCPClient are optional functions.

[0123] ASN must increase AAA Proxy (proxy) function.

[0124] As shown in Figure 10, the main functions of the architecture of this example are as follows:

[0125] 1, 2, 3, 7, 8 are the same as Example 1;

[0126] 4. For IPv4, G-RS PMIP Client, G-RS FA (proxy G-Host), ASN FA (proxy G-RS) and CSN HA are used to support simple IP-based G-Hos...

Abstract

The invention discloses multiple host network architecture and gateway device, which is used to solve the problem that the existing WiMAX network architecture generates too high ASN and G-MS resource consumption and can not support the host devices based on the 802.16 radio transmission protocol. The multi-host network architecture of the invention includes: at least two host devices, and internetworking access server ASN and connection service network CSN; the described network also includes gateway device, which is connected with all host devices via the first interface and connected with the ASN via the second interface.

Description

technical field [0001] The invention relates to the field of wireless networks, in particular to a multi-host network architecture and gateway equipment in a WiMAX network. Background technique [0002] IEEE 802.16 is the first broadband wireless access standard. There are two main versions: broadband fixed wireless access version based on 802.16 standard; broadband mobile wireless access version based on "802.16-2004" and 802.16 standard, namely "802.16e ". Only base station BS and subscriber station SS are defined in 802.16-2004 and 802.16e. [0003] At present, 802.16j only proposes the concept of WiMAX transfer station RS. An important function of the RS is to serve as a transfer between BS and SS / mobile station MS, increasing the throughput and transmission reliability of user stations. IEEE 802.16 only defines the physical layer PHY and data link layer MAC, RS does not yet support the gateway function. [0004] The WiMAX Forum defines the WiMAX network architecture ...
