Although modern Smart Car technologies are growing rapidly, there are many challenges to be addressed. The limited processing capabilities of the contemporary in-car computers in smart cars may cause bottlenecks in smart control. The content in smart car applications can hardly be extended. In addition, the traditional software installation approach that is used in smart cars is neither economical nor convenient.To address these issues in smart cars, we introduced a Cloud-based Information Integration Platform for Smart Cars that has the ability to improve flexibility in the smart car information platform and enhance the value of smart cars. In this work, the architecture of the Cloud-based Information Integration Platform was designed by adapting new technologies, such as Cloud computing, Web Services and Controller Area Network (CAN). This service-oriented solution has a vertically integrated architecture that uses full information gathering and service driven synergies. To achieve the smart control and information sharing in smart cars, the designed platform collects data through the CAN bus automatically, analyses and meshes that data to smart car information services in the cloud. We also designed a Smart Car Information Service as the user interface to implement smart car applications through customized business processes. This fills the information processing gap between the smart car and cloud computing. Furthermore, we can use the information integration platform for different usage scenarios, such as car diagnosis, car repair, etc.

“…The session initiation protocol (SIP) [26] is probably the best choice, since it has been selected by the 3GPP as the fundament for the IP Multimedia Subsystem, and as a consequence the SIP stack will be found soon in all next generation mobile phones. Thus, the location system described in previous works (NILS -Native IMS location system [19], [24], [25]) has nice properties: it is IMS-aware and it is completely independent of the current GSM/UMTS network-based location system. The solution described in more detail in the next sections requires implementing in each mobile terminal a component similar to an edge presence server.…”

“…Instead of regarding access control mechanisms to protect location information, Beresford [19] focuses in his Dissertation on a class of location applications, where privacy can be realized through anonymity and pseudonymity, and investigates the degree of anonymity a user still has if he moves in a so called mixed-zone, i.e. between zones in which applications may track him.…”

“…This location data may consist of geographical coordinates, access point cell IDs, or civil location in form of postal addresses. Some of the privacy problems arising through disclosure of location information have been solved in the past through anonymity and pseudonymity [22], [4] achieving unlinkability between user identity and position data, and between successive locations of the same user [6], [19]. Location privacy should to be protected also when the interacting parties and services trust each other: however, for communicating friends or even within the family, hiding the identity behind pseudonyms does not make much sense [15].…”

A System for Locating Mobile Terminals with Tunable Privacy

A number of approaches for capturing and processing location information of mobile users have been proposed in the past; however, only with the latest advances in the handset technology, a terminal-based positioning approach, using overlay SIP signaling on top of a packet switched bearer and area notification as basic functionality becomes feasible for mass applications. Especially in electronic commerce scenarios, in which users often interact with non-trusted services and shops, any location-based solution has to consider privacy aspects as well. The terminal-centric model presented in the paper leads to a simple and efficient way to achieve tunable privacy: mobile users define own "zones" and selectively disclose them to their buddies and to external services. As a result, localization can be performed only in the allowed places and by the allowed watchers, both parameters being configured by the user herself on her mobile terminal. We describe the system architecture, protocols and present representative technical scenarios.

Nach einhelliger Einschä tzung von Netzbetreibern, Dienstanbietern, Equipmentherstellern und weltweiten Standardisierungsgremien ist das 3GPP IP Multimedia Subsystem (IMS) derzeit der vielversprechendste Kandidat fü r die grundlegende Architektur eines Next Generation Networks (NGN), welches die herrschende Kluft zwischen leitungs-und paketbasierten Netzen ü berbrü cken und beide Seiten zu einem einzigen Netzwerk fü r alle Dienste konsolidieren soll. Daher ist die bevorstehende kommerzielle Einfü hrung des IMS von kaum zu ü berschä tzender Wirkung sowohl auf die Migration des Core-Netzwerks als auch auf die Integration kü nftiger mobiler Dienste und Applikationen. Die vorliegende Arbeit bietet hierzu eine praktische Standortbestimmung aus Mobilnetz-orientierter Perspektive, wie sie im Rahmen des ftw.-Projekts CAMPARI in den letzten Monaten erarbeitet wurde. Der erste Teil des Beitrags dient einer nä heren Vorstellung dieses Projekts, insbesondere im Hinblick auf die darin vorgenommene Realisierung eines Open Source-basierten experimentellen Testsystems als Minimalversion eines weitgehend standardkonformen IMS Core-Netzes. Im zweiten Teil werden sodann zentrale offene Fragen im Zusammenhang mit IMS-Vergebü hrung, Identitä tsmanagement, Migration, Sicherheit und regulatorische Aspekte wie IMS-Notrufe und Abhö rmaßnahmen diskutiert. Schlü sselwö rter: IP Multimedia Subsystem; 3GPP; Next Generation Network, IMS-Testsystem; IMS-Vergebü hrung; Identitä tsmanagement; Migration; Regulierung Quo vadis, IMS? Position and perspectives for the IP Multimedia Subsystem in a mobile networking context.According to the unanimous estimation of network operators, service providers, equipment manufacturers and international standardization bodies, the 3GPP IP Multimedia Subsystem (IMS) at present is the most promising approach for the basic architecture of a Next Generation Network (NGN), which is supposed to bridge the current gap between circuit-switching and packet-switching networks and to consolidate both sides into a single network for all services. Therefore, the imminent commercial introduction of IMS will be of tremendous impact both for the migration of the core network and the integration of future mobile services and applications. In this context, the present article investigates position and perspectives of IMS in a mobile networking context as developed within the ftw.-project CAMPARI. The first part of the paper starts with a survey of this project and describes our realization of an open source-based experimental testbed as minimal version of a widely standard compliant IMS core network. Based on this, in the second part we then discuss some basic open issues related to IMS charging, identity management, migration, security and regulatory aspects like IMS emergency calls and legal interception.
