Divergent innovation: Fostering and managing the fuzzy front end of innovation

Abstract: Early phases of innovation are hardly ever being addressed in a systematic way. We tend to assume that ideas fall like raindrops from the sky. Within the concept of open innovation the number of input channels has been increased, but the assumption remains that new ideas pop up by chance or brainstorming. The process of generating new ideas in engineering, science and design is usually considered ill-defined, or even random. In contrast to this view we describe approaches of divergent innovation and search field analysis and three alternative methods that may be applied within: (1) futures-oriented approaches, (2) contextual approaches and (3) the resource-oriented derivation of product attributes from value propositions. We exemplify a divergent approach by showing a project to allocate potentially disruptive innovation for the telecommunication industry. Finally, we derive implications and guidelines for future market research within a divergent innovation approach.

Method for advertising in speech-supported telecommunication links

Abstract: The method provides importing advertising information into a telephone connection and providing an advertising dialogue system configured to assist in importing the advertising information into the telephone connection and to manage the advertising information and an advertising action which are looped into the telephone connection. The method further provides assigning at least one action indicator and a start action instruction to the advertising information. The at least one action indicator is configured to indicate the advertising action possible with the advertising information. The start action instruction is configured to start the advertising action, the start action instruction being triggerable by a user and activating the advertising action associated with the advertising information managed by the advertising dialogue system. The advertising dialogue system provides any service associated with the advertising action as automatically available to the user.

Apparatus, method, manufacture, and system for providing network services from building blocks

Abstract: A method and apparatus for communicating over a network is provided The method includes obtaining building block codes, where the building blocks codes are capable of being used together to provide an end-to-end service The building block codes are sent to each appropriate building block controller, where each building block controller is associated with a corresponding network node Upon receiving a first packet of a connection for the first end-to-end service, a determination as to which network nodes of the plurality of network nodes should be used as network hops for the connection, and as to, for each network node that should be used as a network hop for the connection, which building block codes should be used by the building block controller corresponding to the network node These determinations are communicated to each of the appropriate building block controllers

Planet-scale human mobility measurement

Abstract: Research into, and design and construction of mobile systems and algorithms requires access to large-scale mobility data. Unfortunately, the research community lacks such data. For instance, the largest available human contact traces contain only 100 nodes with very sparse connectivity, limited by experimental logistics. In this paper we pose a challenge to the community: how can we collect mobility data from billions of human participants? We re-assert the importance of large-scale datasets in communication network design, and claim that this could impact fundamental studies in other academic disciplines. In effect, we argue that planet-scale mobility measurements can help to save the world. For example, through understanding large-scale human mobility, we can track and model and contain the spread of epidemics of various kinds.

High resolution estimation of the time of arrival for GSM location

Abstract: Location services in cellular systems have become more and more important. One of the reasons is the Federal Communications Commission's (FCC) requirement to determine the position of a mobile user within an root-mean-square accuracy of 125 meters. A number of location techniques are based on the estimation of the time of arrival (TOA) or the time difference of arrival (TDOA) of the line-of-sight (LOS) signal component. However, due to multipath propagation and the limited bandwidth available in GSM or in other narrowband systems, an accurate TOA-estimation using conventional methods is hardly achievable. In this paper TOA-estimations using the modified-least-squares-Prony (MLS-Prony) and the Root-MUSIC techniques are presented. Moreover, the performance of both techniques is evaluated through simulations of a GSM transmission over different multipath channels.
