Abstract: A method and a computer system arrangement for minimizing communication and integration complexity between a plurality of external systems and/or software applications having each an individual data model defining an individual set of application parameters is disclosed. Specifically, the method and the computer system, or abstraction layer, have connections to each one of the plurality of external systems and/or software applications, where the computer system includes a plurality of adapters arranged to interpret between an external system and/or software application and to orchestrate incoming and outgoing requests from an external system and/or software application.

Abstract: Whether a service is available for use by a mobile station in a radiocommunication system is ascertained by determining a quality value that represents the mobile station's transmission power capability that is above an amount of transmission power that will be consumed by known losses for the service and determining whether the service is available for use by the mobile station on the basis of a comparison between the quality value and a predetermined number. The quality value may be determined by subtracting the amount of transmission power that will be consumed by known losses for the service from a maximum available power that the mobile station can deliver. Known losses may include the power loss on a channel between the mobile station and a base station, the amount of power that is needed to overcome interference, and the amount of power needed to accommodate the service.

Abstract: A method and system for locating mobile stations within a mobile communication network including at least two mobile stations and at least three base stations. Signal measurements are performed at the mobile stations and/or the base stations. Two or more mobile stations are located simultaneously by minimizing a cost-function, which is achieved by means of a sufficient number of equations, wherein the equations comprises the location of the mobile stations as a function of the location of one of the base stations in the network and the performed signal measurements.
