Roaming, Handover, mobility management
Even though the PMIP provides mobility solutions, there are many issues of user identity, mobility context of users from a home network to the visiting network, the assignment of home address to a user terminal in a visiting network, identification of the user terminal’s mobility, and identification of MPA and HA. In this paper, we propose a new mechanism with proxy mobile IPv4, as a mobility solution in networks. In this mechanism during mobile node access authentication, MPA exchanges registration messages with the HA (Home Agent) to set up a suitable routing and tunnelling for packets from/to the MN. In this method, the authentication request of the mobile node is passed through the NAS or AP of visiting network, this is then passed to the AAA (Authentication Authorization and Accounting) server, and the authentication server checks the realm and does start authentication procedure at the time of initialling authorizing module of the mobile terminal. It also initiates the mobility extension module, where the AAA server initiates MPA of the access network, which also informs the AAA server of the home network with information on the mobility extensions and request of the mobility parameters of the user terminal. The home AAA server interacts with the HA and collects mobile node parameters, as well as sending back details as a reply request to the visiting AAA server. After the mobility context transfer, the MPA conducts a mobility registration to the HA for that particular mobile node. Later in this paper, we will provide sequence of message exchanges during a mobility session of a user mobile node during handover.
