“…[8]. Since most user-to-user messaging is either Internet based or telephony based, unified messaging is sometimes defined as; "Internet-based integration of telephony and data services spanning diverse access networks" [6]. Neither of these approaches to unification comes close to ours.…”

Abstract. There is growing trend to unify user-to-user messaging systems to allow message exchange, independent of time, place, protocol, and end-user device. Building gateways to interconnect existing messaging systems seems an obvious approach to unification. In this paper we argue that unification should take place at the level of the underlying messaging models. Such a unification results in one messaging model that has maximum adaptability, allowing one system to deliver the same messaging services that all currently existing messaging systems deliver, as well as hitherto impossible mixes of those services. We present a novel unified messaging model that supports maximum adaptability. Our approach supports the same services that all current messaging models support, including those of e-mail, fax, SMS, ICQ, i-mail, USENET News, AIM, blog, MMS, and voicemail. To substantiate the claim that such a unified model can be implemented efficiently on a worldwide scale, we present the design of an accompanying highly adaptable and scalable messaging middleware system.

“…In contrast, personal and session mobility schemes (e.g., The Mobile People Architecture (MPA) [16] ICEBERG [30], and Telephony Over Packet networkS [1]) track people or sessions. This allows redirection of new sessions or migration of active sessions to a completely different application or device according to user connectivity (e.g., which devices are currently accessible to the user) and user preferences (e.g., less expensive or higher performance).…”

“…Personal/session mobility allows a user to redirect a new session or migrate an active one from one application or device to another when a better choice becomes available [1] [16] [30]. Applications or devices may fail (e.g., a cell phone may have poor coverage indoors) or a better performance/price option may become available (e.g., video conferencing on a laptop connected to a free 11Mb/s 802.11b network is preferable to a cell phone connected to a 128Kb/s GPRS network).…”

Host Mobility Using an Internet Indirection Infrastructure

et al. 2005

We propose the Robust Overlay Architecture for Mobility (ROAM) to provide seamless mobility for Internet hosts. This architecture uses an indirection infrastructure that provides a rendezvous communication abstraction: instead of explicitly sending packets to a destination address, packets are sent to an identifier. A receiver who wishes to receive those packets uses the indirection infrastructure to associate its address with the identifier.ROAM allows end-hosts to avoid the inefficiency of triangle routing by choosing nearby indirection points, and it is as robust as the underlying IP network to node failure. In addition, it preserves location privacy and allows end hosts to move simultaneously. We have developed a user-level prototype system on Linux that provides transparent mobility without modifying applications or the TCP/IP protocol stack. We also present both simulation and experimental results.

“…The ICEBERG [18,29] project at Berkeley builds a signaling and service infrastructure using advanced cluster computing technology and a novel access point architecture. The IAP access points are used to interconnect mobile devices (GSM telephones and 802.11 laptops are described in the papers) to the Internet, and provide signaling and call setup services to the mobile user which seem superior to H.323 and SIP [9] in the ICEBERG team's analysis.…”

The recent widespread deployment of wireless LAN technology raises the question of how a mobile telephony system might instead be architected to use wireless LAN access points and the Internet to achieve similar services. In this paper, we examine an end-to-end architecture for mobile telephony, with a strong focus on endpoint issues.We have designed, implemented, and have experience using devices we call Internet Mobile Phones or IMPs. The IMP system provides encrypted wireless voice communication over 802.11B LANs. IMPs run Linux on a lightweight single-board computer running customized voice over IP software; data is encrypted with 128-bit Blowfish.The paper reports on our design decisions and the resulting implementation of the IMPs, with sufficient detail to reproduce the devices. We report our experiences with using them for several months in a laboratory environment, and close with proposals for future experiments to investigate scale and extensibility.
