The basic idea of the invention is to separate the location area used in the RAN and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.

A method for describing software architecture utilizes a service concept to provide a map of the software system's features from top-level functionalities to actual code through all intermediate abstractions. The services are defined as logical and physical services. Physical services are bound to a given level of abstraction by the actual implementation, whereas logical services can be hierarchically divided into smaller logical services. A suitable abstraction level can be used for the logical services so that the best match between physical and logical services can be achieved. Linking physical services to logical services is done so that the set of physical services that implement a set of logical services can be found in a top-down fashion. Also the set of logical services that is implemented by a set of physical services can be found in the bottom-up fashion. The logical service structure can be used as a reference software architecture.
