Chip card having transmitting and receiving device, and antenna for radio transmissions

Abstract: The invention relates to a SIM card ( 21 ) or chip card ( 20 ), particularly for authenticating at least one mobile terminal, wherein the SIM card ( 21 ) comprises at least one processor ( 1 ) and contact areas ( 22 ) for connecting the SIM card ( 21 ) to a mobile terminal, wherein the SIM card ( 21 ) comprises an antenna ( 15, 23 ) or comprises further contact areas ( 14, 24 ) for connecting to an antenna ( 15, 23 ), and that the SIM card ( 21 ) comprises a radio interface ( 200 ) for establishing and maintaining a short-range radio connection.

(Re-)actions speak louder than words? A novel test method for tracking user behavior in web video services

Abstract: Assuring user engagement has become a key issue for Internet Service Providers and Over-the-Top Providers. How long are users consuming a service? When are they likely to abandon it due to quality problems? Rather than just estimating perceived audiovisual quality, future quality prediction models will also factor in possible user behavior. This contribution presents a novel test method to assess short-term user behavior in web video services, in a controlled living-room-like environment. We show that typical behavioral responses (such as seeking, reloading, or selecting another video) can be elicited, with the real purpose of the test hidden from the viewers. We can also see that when users are not focused on judging quality, their perception of errors changes significantly. This paper highlights the strong impact of laboratory test situations on users' behavior and discusses the challenges revolving around finding valid test methods.

vNurse: Using virtualisation on mobile phones for remote health monitoring

Abstract: We present vNurse, a system based on a smartphone platform that permits comprehensive, secure and modular patient remote monitoring outside a clinical environment, eg in the home Using both virtualisation of the phone OS and virtual mobile networks of sensors with full Internet Protocol (IP) connectivity, we enable real-time remote sensor readings of patient Wireless Body Area Networks (WBANs) to be stored, processed and forwarded securely to healthcare practitioners based at clinical sites, while patients are remote or mobile

Service creation & delivery for SME based on SOA / IMS

Abstract: Modern telecommunication networks and classical roles of operators are subject to fundamental changes. Standardization bodies and the industry are specifying and integrating Next Generation Network (NGN) infrastructures and NGN services based on an all-IP paradigm. The IETF, ETSI, 3GPP, 3GPP2 and OMA are working on technological issues to enable services using Internet technology and Service Orientated Architectures (SOA).This paper reports about the German research project Multi-Access Modular-Services Framework (MAMS) funded by the German Federal Ministry of Education and Research (BMBF). It targets the access of Small and Medium Enterprises (SME) with an easy usable system, which allows creating and delivering new services without deep technical expertise.It focuses on the use of standardized telecommunications architectures and APIs for Network Abstraction to glue emerging telecommunication architectures with 3rd party services, the Internet and vice versa.

TinySIP: Providing Seamless Access to Sensor-based Services

Abstract: Recent technological trends are transforming sensor nodes from passive data-gathering entities to a collaborative network of sensors, capable of providing data-related and event-related information services. Such a sensor-based information service is useful only if it cain be seamlessly accessed across traditional networks and through familiar device interfaces. In order to enable such ubiquitous access to sensor-based services, we need a remote messaging protocol that supports versatile messaging options, interoperates over different types of network, and allows messages to be routed based on flexible attribute-based addressing of endpoints. Furthermore, in order to ensure ease of adoption and deployment within an enterprise as well as in consumer environments, we must leverage communication abstractions that are well-known and already supported on traditional networks. In this paper, we propose TinySIP as a communication abstraction for accessing sensor-based services. TinySIP is based on the Session Initiation Protocol (SIP), which is a standard application-level signaling mechanism. Users on traditional networks remotely interact with a sensor network service by sending SIP messages. A gateway maps the SIP abstractions to the corresponding TinySIP abstractions and propagates the messages to the sensor nodes. We are currently planning on deploying the SIP-based solution that we propose on a research testbed to enable users on a wireless mesh to access the in-network storage and event correlation services offered by a sensor network consisting of 20 MicaZ sensor nodes.
