Abstract:
1. A method for fast GPRS in a GPRS network that includes an IPv6 layer and a MAC layer, comprising: (a) in response to receiving a GPRS routing area update message at a mobile node, employing an adapter at a MAC layer of the mobile node to generate a router advertisement message, wherein the router advertisement message is communicated to an IPv6 layer on the mobile node; (b) generating a care of address at the IPv6 layer on the mobile node based on a router advertisement message; and (c) generating a Mobile IPv6 Binding Update at the IPv6 layer on the mobile node, wherein the Mobile IPv6 Binding Update comprises the generated care of address; (d) employing the adapter at the MAC layer of the mobile node to encapsulate the Mobile IPv6 Binding Update message into a routing area request, wherein the routing area request is communicated to the GPRS network, and wherein the routing area request includes an information element associated with a predetermined routing type that is employed by the GPRS network for IP level routing with the mobile node.
