Abstract

When PMIPv6 and MIPv6 protocols are deployed in a network where multiple HAs collocated with LMAs are deployed and a mobile node moves from a MIPv6 network to the PMIPv6 home domain, the MAG must select the particular LMA collocated with the MN's HA in the previous MIPv6 domain, otherwise packets addressed to the MN will be dropped, vice versa. Two interaction mechanisms are proposed for solving the issues existing between a MIPv6 domain and a PMIPv6 domain. The MN's HA registers its address at the MN's AAA server after the MIPv6 registration over, and then the MN's MAG retrieves the HA address during the authentication phase and initiates the PMIPv6 registration procedure when the MN enters a PMIPv6 domain. The process procedure is identical to the former solution when the MN roams to a MIPv6 domain from a PMIPv6 domain. The sole difference is the LMA address instead of the HA address. The proposed schemes improve the mobility management performance of the interaction between a MIPv6 domain and a PMIPv6 domain and enhance the capability of network deployment.
