Location detection via cell-ID of mobile devices

Context of the trial: The user shall be provided with personalized messages informing him about appropriate places/opportunities whilst roaming in the city. The user has been actively or passively located and messages containing content following his personal profile are being sent, the user is routed then to the place of his interest.
Localisation via cell-id was used for active and passive localisation of customers. The implementation has been done by using the 3rd party - interface of a mobile network operator in France. In case of passive localisation in addition Openwaves "Location Studio" was implemented to consider the privacy settings of the customer (see separate description). No major problems occurred during the technical implementation and execution of this trial. One of the challenges raised whilst implementing the applications for passive localisation was related especially to the handling of the geo-coordinates. But it could been solved without major problems.
The main conclusion of the first trial was that the mobile network cell-id-technology for positioning at the city where the trial took place was not accurate enough for a pedestrian routing to the requested destinations.

Thus, for the second trial the positioning via GPS was implemented in addition (see separate destription)as a stand alone - solution. The positioning via GPS in our case was used completely separate and in addition to the possibility to be localized by the mobile network and gave us the possibility of a much more accurate positioning of a pedestrian user (about 10m).

However, the combination of the positioning by using mobile network cell-id technology and GPS fits perfect into the picture of the roadmap of most of the mobile network operators concerning their positioning technology strategy. Network operators plan to launch a so called “Assisted GPS” solution. “Assisted GPS” is a combined solution of the “classical positioning” in mobile networks and the positioning via GPS. A-GPS (Assisted GPS) will allow a much more accurate positioning of the user then it is possible in mobile networks today and will increase the possibilities of mobile service offers, e.g. to pedestrians. A-GPS requires mobile network and mobile terminal support and is planned to be launched in the first mobile networks in 2004.
