1. A method in a mobile node, the method comprising:
- determining that a wireless local area network (WLAN) in communication connectivity with the mobile node is directly connected to a home public land mobile network (HPLMN) of the mobile node;
in response to the determining, causing an identifier module of the mobile node to retrieve an alternative network address identifier (NAI) based on the mobile node determining that the alternative NAI will cause authentication to fail;
sending, from the mobile node to the WLAN, a message comprising the alternative NAI;
based on the alternative NAI, receiving, at the mobile node from the WLAN, a list that identifies any public land mobile network (PLMN) accessible via the WLAN; and
communicating with a PLMN from the list different from the HPLMN.

Abstract
Apparatus, and an associated method, by which to permit selection by a user of a mobile node of with which cellular communication system network that the mobile node shall communicate by way of an interworking wireless local area network. User selection is provided even when the interworking wireless local area network is directly connected to the home network of the mobile node. A determiner determines whether the interworking wireless local area network is directly connected to the home network. And, responsive to the determinations, an identifier identifies the cellular communication system network associated with the interworking wireless local area network.

5. A method in a wireless local area network (WLAN) comprising:
-
receiving, from a mobile node, a message comprising an alternative network address identifier (NAI), the alternative NAI selected by the mobile node based on the mobile node determining that the alternative NAI will cause authentication to fail and in response to determining a direct connection between the WLAN and a home public land mobile network (HPLMN) of the mobile node; sending, to the mobile node, a list that identifies any public land mobile network accessible via the WLAN, the list being sent based on receipt of the alternative NAI; and routing communication from the mobile node to a PLMN on the list different from the HPLMN. - View Dependent Claims (20, 21)
