Abstract: The present invention discloses a method of accessing a network service via a mobile end device of a user in a wireless network wherein a first localisation procedure is performed in order to ascertain a position of the mobile end device. The availability of the network service is determined if the mobile and device is within or is about to enter a predetermined zone in which the network service is available. Then, the number of users of said network service in said zone is determined by using a second localisation procedure. Dependent on the number of users of the network service in said zone, one or more parameters for access of the network service by the mobile end user are set.
