Abstract
The invention relates to a method, an element, and a system for providing access authentication for a user using user equipment (1-2) communicating (1) in a first communications network (1-30) accepting a first type of identification to a second communications network (1-16, 1-20) accepting a second type of identification. In the invention, an identifier comprising a first part and a second part is received (5); a corresponding second part is retrieved (7) from a database (BSF) by using the first part; the received second part is compared with the retrieved corresponding second part; and if they are the same, the user equipment (1-2) is provided with access authentication to the second communications network (1-16, 1-20).

15. A method of providing access authentication for a user using user equipment communicating in a first communications network accepting a first type of identification to a second communications network accepting a second type of identification, comprising:
-
authenticating the user equipment to the first communications network by the first type of identification; creating an identifier used in the second type of identification in response to the authentication of the user equipment to the first communications network; and receiving the identifier of a second type, the identifier comprising a first part and a second part; retrieving, using the first part, a corresponding second part from a database; comparing the received second part with the retrieved corresponding second part; and
if they are the same, providing the user equipment with access authentication to the second communications network. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 28)

26. A server element for providing access authentication for a user using user equipment communicating in a first communications network accepting a first type of identification to a second communications network accepting a second type of identification, comprising:
-
means for authenticating the user equipment to the first communications network by the first type of identification; means for creating an identifier used in the second type of identification in response to the authentication of the user equipment to the first communications network; means for transmitting the identifier of the second type, the identifier comprising a first part and a second part; and means for retrieving, using the first part, a corresponding second part from a database; means for communicating the corresponding second part for comparison of the transmitted second part with the retrieved corresponding second part; and
means for providing the user equipment with access authentication to the second communications network if the transmitted second part is the same as the retrieved corresponding second part are the same.

27. A system for providing access authentication for a user using user equipment communicating in a first communications network accepting a first type of identification to a second communications network accepting a second type of identification. comprising:
-
an element for authenticating the user equipment to the first communications network by the first type of identification; a proxy element for receiving an identifier of a second type from the user equipment, the identifier comprising a first part and a second part; a server element for retrieving, using the first part, a corresponding second part from a database and for transmitting the corresponding second part to the proxy element; and the proxy element for comparing the received second part with the corresponding second part; and
if they are the same providing the user equipment with access authentication to the second communications network.
