This specification defines a Uniform Resource Name (URN) namespace for the Global System for Mobile Communications Association (GSMA) and a Namespace Specific String (NSS) for the International Mobile station Equipment Identity (IMEI), as well as an associated parameter for the International Mobile station Equipment Identity and Software Version number (IMEISV). The IMEI and IMEISV were introdu...

The technologies of mobile communications and ubiquitous computing pervade our society, and wireless networks sense the movement of people and vehicles, generating large volumes of mobility data. Miniaturization, wearability, pervasiveness of mobile devices are producing traces of our mobile activity, with increasing positioning accuracy and semantic richness: location data from mobile phones (...

The Advanced Communications Technology Satellite (ACTS) Mobile Terminal (AMT) is a proof-of-concept K/Ka-band mobile satellite communications terminal under development by NASA at the Jet Propulsion Laborato~. Currently the AMT is undergoing system integration and test in preparation for a July 1993 ACTS launch and the subsequent commencement of mobile cxpcrimcnts in the fall of 1993. The AMT o...

With the constant development of customer relationship management (CRM) theory and the maturity of business intelligence technology, the analysis-based CRM has become a hot topic in the academic field. Some enterprises have begun to put the analysis-based CRM to practice; however, there have been few successful applications because of the inadequate mastery of business intelligence technology a...

Railway environments cannot be away from the current evolution of public communication systems. The Long Term Evolution (LTE) mobile communication system is considered to be the natural evolution for current Global System for Mobile Communications Railways (GSM-R). LTE all IP networking technology plays a key role for the integration and convergence of heterogeneous networks and services, both ...

The tremendous demands from social market are pushing the booming development of mobile communications faster than ever before, leading to plenty of new advanced techniques emerging. With the converging of mobile and wireless communications with Internet services, the boundary between mobile personal telecommunications and wireless computer networks is disappearing. Wireless networks of the nex...

Reducing CO2 emissions is an important global environmental issue. Over the recent years, wireless and mobile communications have increasingly become popular with consumers. Today’s typical wireless access network consumes more than 50% of the total power consumption of mobile communications networks. Growth of mobile Internet service usage is expected to drive the growth in wireless access dat...

One of the stated aims of 3 Generation mobile communications systems is to provide enhanced multimedia services to the user. Such services will include an integration of video, high-quality audio and data services. This paper describes a real-time mobile video communications system which employs ETSI’s GPRS mobile packet system as a mobile access medium. Subjective performance tests are carried...

The comprehension of phenomena related to movement – not only of people and vehicles but also of animals and other moving objects – has always been a key issue in many areas of scientific investigation or social analysis. Many applications track the movement of mobile objects, using locationacquisition technologies such as Global Positioning System (GPS), Global System for Mobile Communications...
