accessing, by a user equipment, an access point to attempt to establish a connection to a communications network comprising at least one of a home public land mobile network and a visited public land mobile network;
receiving, in response to the accessing resulting in a failure in the attempt to establish the connection and before an extensible authentication protocol failure message is received, an extensible authentication protocol notification message at the user equipment, the extensible authentication protocol notification message indicating at least one reason for the failure in the attempt to establish the connection to the communication network interworking with the access point, the at least one reason for the failure comprising information indicating whether the failure was due to a temporary unavailability of the access point and/or the communications network, the extensible authentication protocol notification message comprising a multi-bit notification code including a first portion of the multi-bit notification code specifying whether the at least one failure occurred;
selecting, in order to access an authentication server at the communication network, the access point, when the at least one reason for failure indicates temporary unavailability, or another access point, when the at least one reason for failure does not indicate temporary unavailability.
2. The method as claimed in claim 1, wherein the message comprises information indicating a cause for the failure.
3. The method as claimed in claim 2, wherein the message comprises at least one of the following:
information indicating that authentication signaling could not be routed to a server;
information indicating that authentication signaling was routed to the server and authentication failed;
information indicating that authentication signaling was routed to the server and authentication failed before an authentication challenge;
information indicating that authentication signaling was routed to the server and authentication failed after the authentication challenge;
information indicating that there is no roaming relationship with a home network;
information indicating a location of the network failure;
information indicating an internal failure in at least one of the access point and the communications network; and
information indicating traffic congestion.
4. The method as claimed in claim 1, further comprising:
selecting the communications network.
5. The method as claimed in claim 1, further comprising:
authenticating the user equipment.
6. The method as claimed in claim 5, wherein the authenticating comprises authenticating the user equipment via the communications network.
7. The method as claimed in claim 1, wherein in response to the message at least one of the following is performed:
selecting a different access point;
selecting a different communications network;
retrying to establish the connection;
retrying an authentication; and
providing identity information.
8. The method as claimed in claim 1, further comprising receiving another message, wherein when the connection fails, the other message indicates the failure.
9. The method as claimed in claim 1, wherein a failure bit in the message is set to a value indicative of the failure.
10. The method as claimed in claim 1, further comprising receiving a plurality of messages, wherein the plurality of messages is in accordance with an extensible authentication protocol.
11. The method as claimed in claim 1, wherein the information in the message comprises at least one error code.
12. The method as claimed in claim 1, wherein the receiving the message comprises receiving information that is at least one of an extensible authentication protocol attribute message and an extensible authentication protocol type-length-value message.
13. The method as claimed in claim 1, wherein the access point is included in a wireless local area network.
14. The method as claimed in claim 4, wherein the selecting the communications network comprises selecting the visited public land mobile network.
15. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code, the at least one processor, the at least one memory, and the computer program code configured to cause the apparatus to at least:
access an access point to attempt to establish a connection to a communications network comprising at least one of a home public land mobile network and a visited public land mobile network;
receive, in response to the access resulting in a failure in the attempt to establish the connection and before an extensible authentication protocol failure message is received, an extensible authentication protocol notification message at the apparatus, the extensible authentication protocol notification message indicating at least one reason for the failure in the attempt to establish the connection to the communication network interworking with the access point, the at least one reason for the failure comprising information indicating�whether the failure was due to a temporary unavailability of the access point and/or the communications network, the extensible authentication protocol notification message comprising a multi-bit notification code including a first portion of the multi-bit notification code specifying whether the at least one failure occurred;
select, in order to access an authentication server at the communication network, the access point, when the at least one reason for failure indicates temporary unavailability, or another access point, when the at least one reason for failure does not indicate temporary unavailability.
16. The apparatus as claimed in claim 15, wherein in response to the message, the receiver performs at least one of:
select a different access point;
select a different communications network;
retry to establish the connection;
retry an authentication; and
provide identity information.
17. The apparatus as claimed in claim 15, wherein the receiver determines that inter-working is not possible when the receiver does not receive the message.
18. The apparatus as claimed in claim 15, wherein the message comprises information indicating a cause for the failure of the attempt to establish the connection.
19. The apparatus as claimed in claim 18, wherein the message comprises at least one of the following:
information indicating that authentication signaling could not be routed to a server;
information indicating that authentication signaling was routed to the server and authentication failed;
information indicating that authentication signaling was routed to the server and authentication failed before an authentication challenge;
information indicating that authentication signaling was routed to the server and authentication failed after the authentication challenge;
information indicating that there is no roaming relationship with a home network;
information indicating a location of the network failure;
information indicating an internal failure in at least one of the access point and the communications network; and
information indicating traffic congestion.
20. The apparatus as claimed in claim 15, further comprising:
a selector to select the access point.
21. The apparatus as claimed in claim 20, wherein the access point is included in a wireless local area network.
22. The apparatus as claimed in claim 15, further comprising:
a selector configured to select a communications network.
23. The apparatus as claimed in claim 22, wherein the selector is configured to select the visited public land mobile network.
24. The apparatus as claimed in claim 15, wherein the receiver is configured to receive another message, wherein when the connection fails, the other message indicates the connection has failed.
25. The apparatus as claimed in claim 15, wherein the receiver is further configured to receive information that is a notification message.
26. The apparatus as claimed in claim 15, wherein a failure bit in the message is set to a value indicative of failure.
27. The apparatus as claimed in claim 15, wherein the receiver is further configured to receive a plurality of messages, wherein the plurality of messages are in accordance with an extensible authentication protocol.
28. The apparatus as claimed in claim 15, wherein the information in the message comprises at least one error code.
29. The apparatus as claimed in claim 15, wherein the receiver is further configured to receive information that is at least one of an extensible authentication protocol attribute message and an extensible authentication protocol type-length-value message.
