RIMA: Router for Integrated Mobile Access
نویسندگان
چکیده
Next generation wireless networks will rely heavily on packet transport for both data and voice services. In this paper, we describe the Router for Integrated Mobile Access (RIMA) system, which is the core network element of an integrated wireless packet network. RIMA acts as a Mobile Switching Center for standard cellular telephony users, and a mobile router for wireless packet data users. RIMA includes a novel call processing system that supports several types of telephony services, and a new IP mobility protocol, called HAWAII, that efficiently manages the IP mobility of data and packet voice users. In this paper, we discuss issues with providing wireless packet service, present a network architecture based on RIMA to address those issues, and describe a research prototype of the system.

Distributing a Symmetric Fast Mobile IPv6 (FMIPv6) Handover Key Using SEcure Neighbor Discovery (SEND)
Fast Mobile IPv6 requires that a Fast Binding Update is secured using a security association shared between an Access Router and a Mobile Node in order to avoid certain attacks. In this document, a method for provisioning a shared key from the Access Router to the Mobile Node is defined to protect this signaling. The Mobile Node generates a public/private key pair using the same public key algo...
متن کاملA QoS Improvement for Mobile Network in Large Vehicles
In large vehicles such as a train, passengers can access Internet through an in-vehicle mobile router to effectively reduce the cost and overhead of roaming to a new network. While we apply the idea of mobile network into large vehicles, the critical issue is how to build up seamless Internet access services between vehicle’s mobile network and fixed networks along the moving path or stations. ...
