Location-aware services (LAS) adapt content and service execution to the user’s current physical location. In today’s cellular networks, only reactive LASs are offered. The user has to explicitly request the service before the network determines her current location and starts service execution. However, in the future the user would like to see proactive LASs, which are automatically triggered as soon as she enters a pre-defined point of interest. In contrast to reactive LASs, this requires that the network performs a continuous user tracking, which entails expensive point-to-point signaling at the air interface.

However, proactive LASs can be supported more efficiently if the mobile terminal locates itself. The terminal can derive its own location by processing location information which is broadcasted by the network or by a dedicated localization infrastructure like GPS. The network does not need to know where the user is, unless she has entered a point of interest. This paper follows this idea and presents the Location-Aware Mobility Architecture (LAMA), a platform for deriving and processing location information at the mobile terminal.
