TL;DR: In this paper, improved capabilities are described for a mobile environment speech processing facility, where speech may be recorded using the mobile communications facility's resident capture facility, and transmission of the recording may be provided through a wireless communication facility to a speech recognition facility.
Abstract: In embodiments of the present invention improved capabilities are described for a mobile environment speech processing facility. The present invention may provide for the entering of text into a music software application resident on a mobile communication facility, where speech may be recorded using the mobile communications facility's resident capture facility. Transmission of the recording may be provided through a wireless communication facility to a speech recognition facility. Results may be generated utilizing the speech recognition facility that may be independent of structured grammar, and may be based at least in part on the information relating to the recording. The results may then be transmitted to the mobile communications facility, where they may be loaded into the music software application. In embodiments, the user may be allowed to alter the results that are received from the speech recognition facility. In addition, the speech recognition facility may be adapted based on usage.

TL;DR: In this article, a mobile location technique using a signal strength measurement scheme is described, and the probability that a mobile is judged to exist in a certain zone (zone selection rate) is defined.
Abstract: In a high-capacity mobile telephone system using cellular technology, a mobile location technique which determines the radio zone in which a moving vehicle exists is one of the most important techniques for the system control. A mobile location technique using a signal strength measurement scheme is described. The probability that a mobile is judged to exist in a certain zone (zone selection rate) is first defined. Dependency of this rate on land mobile propagation characteristics is then discussed in detail. A field test for the justification of this location technique was carried out in the Tokyo metropolitan area in which the field test results agreed well with the estimated values.

TL;DR: This paper presents a practical approach to m-learning and calls it "mobile interactive learning objects" (MILOs) which are used within a mobile learning engine (MLE) that runs on mobile phones.
Abstract: The widespread use of mobile phones (in Europe often called "handles") enables a long awaited dream: learning at any place, at any time. This "not being tied to particular locations" is for example especially interesting in the area of medicine i.e. for vocational training of medical staff and students. As the amount of medical information continues to grow, timely access to information is critical to medical personnel. However, such applications can not be the 1:1 transformation of standard computerized learning material; special design issues must be considered. In this paper we present a practical approach to m-learning and call it "mobile interactive learning objects" (MILOs) which are used within a mobile learning engine (MLE) that runs on mobile phones. MILOs can offer manifold possibilities for new kinds of communication and explorative learning.

TL;DR: It is demonstrated that decoupling can lead to significant gains in network throughput, outage, and power consumption at a much lower cost compared to other solutions that provide comparable or lower gains.
Abstract: Ever since the inception of mobile telephony, the downlink and uplink of cellular networks have been coupled, i.e. mobile terminals have been constrained to associate with the same base station (BS) in both the downlink and uplink directions. New trends in network densification and mobile data usage increase the drawbacks of this constraint, and suggest that it should be revisited. In this paper we identify and explain five key arguments in favor of Downlink/Uplink Decoupling (DUDe) based on a blend of theoretical, experimental, and logical arguments. We then overview the changes needed in current (LTE-A) mobile systems to enable this decoupling, and then look ahead to fifth generation (5G) cellular standards. We believe the introduced paradigm will lead to significant gains in network throughput, outage and power consumption at a much lower cost compared to other solutions providing comparable or lower gains.
