Access through non-3GPP access networks
First Claim
1. A method performed by a user equipment for communication through an access network, comprising:
- retrieving information from, or interpreting a condition indicated by, a message sent to the user equipment from a Third Generation Partnership Project (3GPP) Authentication, Authorization, Accounting (AAA) server in a 3GPP home network of the user equipment, in an authentication procedure being part of establishing a connection from the user equipment through the access network, the information or condition relating to whether the access network is trusted or not, the retrieving occurring before the connection is established; and
using, in a following stage of the procedure of establishing the connection, the retrieved information or the result of the interpreting of the condition for selecting an appropriate way of establishing the connection through the access network.

Abstract
When setting up communication from a user equipment UE (1), such as for providing IP access for the UE in order to allow it to use some service, information or an indication of at least one network property relating to a first network, e.g. the current access network (3, 3′), is sent to the UE from a node (13) in a second network such as the home network (5) of the subscriber of the UE. The information or indication can be sent in a first stage of an authentication procedure being part of the setting up of a connection from the UE. In particular, the network property can indicate whether the access network (3, 3′) is trusted or not.

1. A method performed by a user equipment for communication through an access network, comprising:
-
retrieving information from, or interpreting a condition indicated by, a message sent to the user equipment from a Third Generation Partnership Project (3GPP) Authentication, Authorization, Accounting (AAA) server in a 3GPP home network of the user equipment, in an authentication procedure being part of establishing a connection from the user equipment through the access network, the information or condition relating to whether the access network is trusted or not, the retrieving occurring before the connection is established; and using, in a following stage of the procedure of establishing the connection, the retrieved information or the result of the interpreting of the condition for selecting an appropriate way of establishing the connection through the access network. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A user equipment for communication through an access network, said user equipment comprising:
one or more processing circuits configured to; retrieve information from or interpret a condition indicated in one of the messages sent to the user equipment from a 3rd Generation Partnership Project (3GPP) Authentication, Authorization, Accounting (AAA) server in a 3GPP home network of the user equipment, in an authentication procedure being part of establishing a connection from the user equipment through the access network, the information or condition relating to whether the access network is trusted or not, the retrieving occurring before the connection is established; and use, in a following stage of the procedure of establishing the connection, the retrieved information or the result of the interpreting of the condition for selecting an appropriate way of establishing the connection through the access network. - View Dependent Claims (10, 11)

12. A 3rd Generation Partnership Project (3GPP) Authentication, Authorization, Accounting (AAA) server in a 3GPP home network of a user equipment, the AAA server being configured to:
-
send information to the user equipment in an authentication procedure that is part of establishing connectivity from the user equipment through an access network; and introduce, in a message included in said information sent to the user equipment, information indicating a condition of whether the access network is trusted or not or modify said message to indicate the condition; wherein the information of the authentication procedure that is part of establishing connectivity is sent to the user equipment before the user equipment has established a connection through the access network. - View Dependent Claims (13, 14, 15, 16)

17. A computer program product comprised in or for use by a user equipment related to a 3 rd Generation Partnership Project (3GPP) Authentication, Authorization, Accounting (AAA) server in a 3GPP home network of the user equipment, the computer program product being an electronic memory carrying computer readable instructions which when run by the user equipment causes the user equipment to:
-
retrieve information from or interpret a condition indicated in one of the messages sent to the user equipment from the 3GPP AAA server, in an authentication procedure being part of establishing a connection from the user equipment through an access network, the information or condition relating to whether the access network is trusted or not, the retrieving occurring before the connection is established; and use, in a following stage of the procedure of establishing the connection, the retrieved information or the result of the interpreting of the condition for selecting an appropriate way of establishing the connection through the access network.

18. A computer program product, comprised in or for use by a Third Generation Partnership Project (3GPP) Authentication, Authorization, Accounting (AAA) server related to user equipments, the computer program product being an electronic memory carrying computer readable instructions which when run by an AAA server in a 3GPP home network causes the 3GPP AAA server to:
-
introduce, in a message included in information sent to one of user equipments related to the 3GPP AAA server, information indicating a condition relating to whether an access network, through which a connection from said user equipment is to be set up, is trusted or not;
ormodify said message to indicate the condition; wherein the message is transmitted to the user equipment before the user equipment has established a connection through the access network.
