Patent ID: 10663556

Abstract:
A method performed in a server node associated with a cellular communication system is disclosed. The method is for validation of a first position indication of a wireless communication device, wherein the wireless communication device is adapted to operate in connection with the cellular communication system. The first position indication is obtained via the wireless communication device by a first positioning system. The method comprises obtaining a serving cell identification of the wireless communication device, obtaining a second position indication of the wireless communication device based on the serving cell identification, and determining whether the first position indication is valid based on whether a metric based on the first and second position indications meets a validation criterion. In some embodiments, obtaining the serving cell identification of the wireless communication device may comprises receiving a first message, which comprises the serving cell identification, signed by a first signature associated with the serving cell, and verifying the serving cell identification based on the first signature. Corresponding computer program product, arrangement and server node are also disclosed.
