Abstract:
1. A method for a user terminal accessing a Home Public Land Mobile Network (HPLMN) of the user terminal via a Wireless Local Area Network (WLAN), the method comprises: obtaining identifications of WLANs detected by the user terminal, wherein the user terminal is covered by more than one WLAN, the more than one WLAN is inter-working with a 3GPP system which comprises a plurality of Public Land Mobile Networks, one of the plurality of Public Land Mobile Networks functions as the HPLMN of the user terminal, and the other of the plurality of Public Land Mobile Networks function as Visited Public Land Mobile Networks (VPLMN) of the user terminal; selecting an identification from the identifications of the detected WLANs; comparing the selected identification with pre-stored identifications of the WLANs directly connecting with the HPLMN of the user terminal; and the user terminal accessing its HPLMN via the WLAN identified by the selected identification that matches the pre-stored identifications of the WLANs directly connecting with the HPLMN of the user terminal.
