Mobile user authentication in connection with access to mobile services

摘要

The present invention relates to a method and a system for enabling a server ( 120 ) on a packet switched network ( 130 ) to authenticate a user of a wireless terminal ( 100 ) prior to granting the terminal access to a service administrated by the server. According to the invention, the wireless terminal ( 100 ) initiates transmission of a first set of user identification parameters to a server ( 120 ) over a first communication path ( 140 ), after which the terminal ( 100 ) transmits a second set of user identification parameters to the server ( 120 ) over a second communication path ( 150 ). The server ( 120 ) then bases authentication of the wireless terminal ( 100 ) on a match between the first set of parameters and the second set of parameters.
