Mobile IP provides an efficient and scalable mechanism for host mobility within the Internet. Using Mobile IP, mobile nodes may change their point of attachment to the Internet without changing their IP address. In contrast to the advantages of Mobile IP, updating the location of a mobile node incurs high signaling costs if the mobile node moves frequently. Thus, IP paging schemes for Mobile IP have been proposed to avoid unnecessary registration signaling overhead when a mobile node is idle. However, they require the additional paging costs and delays associated with message delivery when a correspondent node sends packets to the idle mobile node. These delays greatly influence the quality of service (QoS) for multimedia services. Moreover, existing IP paging schemes do not consider a hierarchical mobility management scheme, which can reduce signaling costs by the significant geographic locality in user mobility pattern. Thus, we propose a novel IP paging protocol which can be used in hierarchical Mobile IPv6 networks. In addition, our proposal can reduce signaling costs for paging and delay using the concept of the anchor-cell. The cost analysis presented in this paper shows that our proposal has superior performance when the session-to-mobility ratio value of the mobile node is low.
