发明名称 Directivity characteristics of mobile terminals
摘要 A method determines mobility characteristics of a mobile terminal by measuring a first and second angular direction of travel of the mobile terminal at a first and second instant. The first angular direction is subtracted form the second angular direction to determine the directivity of the mobile terminal during an interval of time between the first instant and the second instant. The directivity, in terms of a mean, variance, or histogram can be used to classify the mobile terminal, and location-aware services can be adapted and delivered according to the classification.
