Client based mobile IPv4 configuration information obtaining method
A technology for configuration information and customers, applied in the field of mobile IP, can solve problems such as inability to carry out services, limit the scope of application of WiMAX networks, and inability to initiate DHCP, etc., to achieve the effect of improving the scope of application and reducing special requirements

Embodiment 1
[0068] This embodiment supplements the DHCP (Dynamic Configuration Protocol) message flow on the original flow to obtain relevant host configuration information. image 3 It is a method for establishing a service connection process in the CMIPv4 mode of this embodiment. Such as image 3 As shown, the method includes the following steps:
[0069] 1) MS authentication and authorization process
[0070] During this process, the AAA sends the DHCP server address or directly sends the host configuration information (Host CI), and the information is sent by the authenticator (Authenticator) to the DHCP relay / proxy (DHCP Relay / Proxy) entity for storage.
[0071] 2), 3), 4) steps are the same as prior art (see figure 2 ), wherein the home address (HoA) is issued to the MS by the HA during the MIP registration process. Here, the entity that allocates the HoA address to the MS, that is, the HA, needs to avoid that the IP address prefix allocated by it is the same as the subnet pref...
Embodiment 2
[0076] In this embodiment, the HoA can first be obtained through the DHCP message flow and the DHCP protocol. The DHCP server address or Host CI and HoA required in the DHCP message flow can be sent to the ASN-GW through the AAA in the process of authentication and authorization. The default DHCP server address or Host CI and HoA information can be pre-configured in the ASN-GW. For example, the DHCP server address is configured in the DHCP relay or the Host CI and HoA information is configured by default in the DHCP agent.
[0077] Figure 4 A method for establishing a service connection flow in the CMIPv4 mode of Embodiment 2 of the present invention; as Figure 4 As shown, the method includes the following processes:
[0078] 1) MS authentication and authorization process
[0079] During this process, the AAA can deliver the DHCP server address, or directly deliver the Host CI and HoA, and if delivered, the information will be sent by the authenticator (Authenticator) to ...
Embodiment 3
[0098] As a supplement to Embodiment 2, it is applicable when the AAA does not issue the HoA address and the DHCP server address, and the DHCP relay / agent does not pre-configure the HoA information (or does not use the pre-configured HoA information), and needs to register through MIP How to obtain the HoA address.
[0099] 1) The process of MS authentication and authorization, in which AAA only issues the Host CI, which is sent by the authenticator to the DHCP proxy entity for storage.
[0100] 2) The initial data channel is established.
[0101] 3) The terminal initiates a DHCP message request (DHCP Discovery) for obtaining the HoA address and host configuration information.
[0102] Steps 4), 5) After receiving the DHCP Discovery message, the DHCP agent triggers the FA to initiate an agent broadcast message, and the agent broadcast message carries the CoA address.
[0103] 6) The terminal initiates a MIP registration request message RRQ after receiving the proxy broadcast...
