Abstract: A method for access authorization includes: generating, by a mobile terminal, first location data in relation to the location of the mobile terminal; comparing the first location data with stored second location data and determining that the first location data matches the second location data; establishing, by the mobile terminal, a first connection to an authorization client using a mobile communication network comprising a base station; sending, by the mobile terminal, identification data to the authorization client to request access authorization; establishing, by a detection client, a second connection to the mobile terminal, wherein the second connection is a direct packet switched connection; and granting access to a user of the mobile terminal when a position of the user relative to the detection client matches a predefined position relative to the detection client.
