WiMAX Forum definition framework as shown in Figure 1 based on the Multiple Hosts (many main frames) of G-RS (gateway terminal)/G-MS (gateway mobile radio station).G-RS/G-MS is connected to a plurality of G-Host by first interface, is connected to ASN (access service network) by second interface.Wherein, first interface is the G-interface interface, and G-interface adopts 802.3 or 802.11 2 layers of tranmission techniques; Second interface is the R1 interface, and R1 adopts the wireless two layers of tranmission techniques of 802.16e.Be connected by the R3 reference point between ASN and CSN (connectivity serving network), be connected by the R5 reference point between the CSN of NAP+V-NSP (Network Access Provider and access zone network service provider) and H-NSP (belonging area network service provider's) CSN.
In WIMAX IPv6 network, adopt the MIPv6 (IP client's mobile IP v 6) of CMIPv6 (IP client's mobile IP v 6) standard at present, referring to RFC 3775.MIPv6 relates to three functional entity HA (home agent), MN (mobile node) and CN (peer-to-peer communications node).The client of CMIPv6 is positioned at MS/G-Host.In the moving process of R3, MS/G-Host carries out (total state or stateless) address and disposes automatically, and the CoA (Care-of Address) of the address of this new formation as it.
MS/G-Host carries out the registration of HoA, and the HA on its home link registers its CoA, MS/G-Host sends the packet that includes " Binding Update " purpose option to its HA, and HA registers this binding and returns a packet that includes " binding acknowledgement " purpose option to MS/G-Host.HA intercepts the packet of all addresses for the home address of this MS/G-Host, and each intercepted data packet is all used the IPv6 encapsulation and adopted tunneling technique to send to the Care-of Address that mobile node is registered.
Method for communicating is between the communication node in a kind of above-mentioned WIMAX IPv6 network of prior art: if a communication node will be communicated by letter with another MS/G-Host that leaves home network, the routing process of packet is: from this communication node to HA, from HA to MS/G-Host, leave the communication node of home network from MS/G-Host to another again.This routing mode is commonly referred to the triangle route.For fear of the triangle routing issue, MS/G-Host can send carry current CoA Binding Update to any one communication node, this communication node gets up the current CoA buffer memory that carries on the above-mentioned Binding Update and directly sends packet to MS/G-Host.
The shortcoming of said method is:
1, this method requires MS must realize Mobile IPv6, can not adopt the MS that only supports Simple IPv6 (simple IP v6), causes MS function complexity;
2, this method need be wasted interface-free resources and carried out CoA registration;
3, because 3G network (as WCDMA) is not supported CMIPv6, communicate according to this method and make the interconnection of WiMAX and 3G network (as WCDMA) become problem;
4, because common G-Host and G-MS/G-RS are the mobile network who is arranged on train, automobile or the steamer, the employed terminal of passenger that G-Host is fixing with respect to G-MS/G-RS often, generally can not realize Mobile IPv6 function, use thereby this method can't be moved in the Multihost network at existing WiMAX.
