Public land mobile network (“PLMN”) discovery communications in a wireless network
View Patent ↗A mobile device may retrieve information about a network prior to associating with the network. For example, the information may be related to a public land mobile network (“PLMN”) and compatibility with Extensible Authentication Protocols (“EAPs”).
1. A method in a wireless device, the method comprising:
transmitting, prior to association of the wireless device with a wireless local area network (WLAN), a request from the wireless device, the request requesting any Extensible Authentication Protocol (EAP) methods supported by a public land mobile network (PLMN) accessible via the WLAN;
receiving, prior to association of the wireless device with the WLAN, a first identifier indicative of a first EAP method supported by the PLMN; and
receiving, prior to association of the wireless device with the WLAN, a second identifier indicative of a second EAP method supported by the PLMN.
2. The method of claim 1 wherein the first identifier and the second identifier are received in response to the request.
3. A wireless device, the device comprising:
a processor configured to:
transmit, prior to association of the wireless device with a wireless local area network (WLAN), a request from the wireless device, the request requesting any Extensible Authentication Protocol (EAP) methods supported by a public land mobile network (PLMN) accessible via the WLAN;
receive, prior to association of the wireless device with the WLAN, a first identifier indicative of a first EAP method supported by the PLMN; and
receive, prior to association of the wireless device with the WLAN, a second identifier indicative of a second EAP method supported by the PLMN.
4. The wireless device of claim 3 wherein the first identifier and the second identifier are received in response to the request.
5. The method of claim 1 further comprising determining, prior to association of the wireless device with the WLAN, whether the wireless device uses the first EAP method or the second EAP method in response to receiving the first identifier and the second identifier.
6. The wireless device of claim 3 wherein the first identifier and the second identifier are received prior to authentication of the wireless device with the WLAN.
