Location-dependent services in mobile communications system

摘要

In mobile communications systems cells are overlapping. This causes problems when location based services are provided to subscribers. In order to overcome the problems, a cell list including the serving cell identity and the neighbouring cell information of a mobile station is formed (3-5) and the cell list is then compared (3-12) with a predefined service area. On the basis of this comparison it is decided (3-12) whether or not the mobile station is in the service area.
