Under the mobile communication network structure of described evolution, the internetwork mobile management scheme of non-3GPP and 3GPP is described below:
Narration by above mobile communication network structure to evolution can obtain: the internetwork mobile management of non-3GPP and 3GPP is finished by Hetero-AS-MM under the mobile communication network structure of this evolution, and be based on the mobile management of IP, access technology for bottom is unknowable, that is to say, the mobile management scheme that the present invention is designed, not only be applicable to the mobile management between 3GPP system and non-3GPP, also be applicable to the mobile management between the non-3 GPP system.
The IP mobile management scheme that the present invention adopts is based on a specific implementation of mobile IPv 4 technology.
Fig. 4 is the workflow diagram of a mobile IPv 4, and as shown in the figure, this workflow is as follows:
1.MN (Mobile Node, portable terminal) sets up be connected (as: ASSN or the PDG) with GW (gateway);
2. the functional module at the FA (Foreign Agent, Foreign Agent) of the mobile IP of GW sends a FA broadcast, comprising the address of FA, uses with the CoA (Care-of Address jump address) as MN;
Judge that it leaves home network (HomeNetwork) and enter a visited network after this broadcast 3.MN receive.Go up then and send out mobile IPv 4 register requirement RRQ, comprising CoA;
4. for the user is carried out authentication, the aaa server of FA and user attaching network is inquired.The ownership aaa server provides a home agent HA and IP address thereof to FA;
5.FA transmit user's RRQ to HA;
6.HA inquire about the key that MN-HA establishes in advance to aaa server.This step only just takes place in registration for the first time, does not need to carry out key when MN connects other FA subsequently again and asks for;
7-8.HA accept the registration of MN, produce the home IP address of MN and the binding of CoA address, and return the registration response of mobile IPv 4.
When terminal the time, be to transmit according to the flow process of Fig. 5 to the data of terminal at visited network.As shown in the figure, when terminal at visited network the time, HA can send proxy ARP information and intercept the data that send to this terminal but be routed to home network.Receive the packet of this terminal as HA after, it inquires the CoA of this terminal from mobile IP mapping table, by the IP-in-IP encapsulation data envelope is installed to a packet to CoA then, and is sent to the visited network of terminal.FA obtains raw data packets by decapsulation, utilizes the transmission mechanism of visited network inside that this packet is sent to terminal then.
