Hi Kar Ann, If you read: draft-sarikaya-seamoby-mipv6hp-00.txt and draft-guri-seamoby-lahap-00.txt you will see defined Layer 2 paging areas (I think that architecture picture in draft-sarikaya-seamoby-mipv6hp is slightly more informative) and Layer 3 PAs. L2 PAs are as in 2.5G and 3G cellular networks so mobile operators define and set up such PAs. There are connected to APs which are L2 entities. They are static. As for L3 PAs, we defined them as collections of IP subnets with a Paging Agent. There is multicast address for each PA and the paging agent can address each PA by a single request message. This is I think a good design and it had previously been proposed (I believe in HAWAII). These PAs are also static. What Pars and Claude talk about as PAs I think is a cell level or L1 concept. I am having difficulty in understanding their theory. Hopefully they will further develop it using L2 or L3 ideas so that we can grasp the theory of dynamic paging areas. Only thereafter some standardization can be thought of. Hope this helps, I do not think that it is all mysterious these PAs. In general IP paging concepts are much better understood now then before. Don't they?
