Methods and apparatus to discover authentication information in a wireless networking environment
Examples to discover network authentication information in a wireless network involve transmitting during network discovery and prior to authentication, a Generic Advertisement Services (GAS) request to a network access point. The request requests authentication information. In addition, a response to the request is received from the network access point. The network authentication information is retrieved from the response. The network authentication information includes a re-direct frame.
1. A method to provide network authentication information in a wireless network, the method comprising:
receiving, by an access point, during network discovery and prior to authentication, a Generic Advertisement Service (GAS) request from a wireless terminal, the GAS request requesting network authentication information; and
transmitting, by the access point and to the wireless terminal, a response to the GAS request, wherein the response includes the network authentication information, the network authentication information includes an authentication type information and a re-direct uniform resource locator (URL) frame, and the authentication type information indicates that the wireless terminal uses the re-direct URL frame for at least one of: (a) obtaining terms and conditions, or (b) hyper text transfer protocol (HTTP)/hyper text transfer protocol secure (HTTPS) redirection.
2. The method of claim 1 , wherein the authentication type information further indicates that the wireless terminal performs at least one of: (a) on-line login enrollment, or (b) domain name server (DNS) redirection.
3. The method of claim 1 , wherein the network authentication information includes a re-direct URL length field.
4. The method of claim 1 , wherein the wireless terminal is a mobile communication device.
5. An access point that provides network authentication information in a wireless network, comprising:
a memory; and
at least one hardware processor communicatively coupled with the memory and configured to:
receive, during network discovery and prior to authentication, a Generic Advertisement Service (GAS) request from a wireless terminal, the GAS request requesting network authentication information; and
transmit, to the wireless terminal, a response to the GAS request, wherein the response includes the network authentication information, the network authentication information includes an authentication type information and a re-direct uniform resource locator (URL) frame, and the authentication type information indicates that the wireless terminal uses the re-direct URL frame for at least one of: (a) obtaining terms and conditions, or (b) hyper text transfer protocol (HTTP)/hyper text transfer protocol secure (HTTPS) redirection.
6. A method for an access point to provide authentication information in a wireless network, the method comprising:
receiving, by the access point, during network discovery and prior to authentication, a Generic Advertisement Services (GAS) request from a wireless terminal, the GAS request requesting authentication information, the authentication information being indicative of an extensible authentication protocol method and indicative of a credential from the wireless terminal to use for authentication of the wireless terminal, and the credential being indicative of a username and password credential; and
transmitting, by the access point and to the wireless terminal, a response to the GAS request from the wireless terminal, wherein the response includes the authentication information.
7. The method of claim 6 , wherein the wireless terminal is a mobile communication device.
8. The method of claim 6 , wherein the response is transmitted at a media access control layer.
9. The method of claim 6 , wherein the credential is obtainable by the wireless terminal.
10. The method of claim 6 , wherein the credential is pre-stored in the wireless terminal.
11. The method of claim 6 , further comprising receiving the credential from the wireless terminal.
12. The method of claim 6 , wherein the credential enables access to a subscription service provider network communicatively coupled to the access point.
13. An access point that provides authentication information in a wireless network, comprising:
a memory; and
at least one hardware processor communicatively coupled with the memory and configured to:
receive, during network discovery and prior to authentication, a Generic Advertisement Services (GAS) request from a wireless terminal, the GAS request requesting authentication information, the authentication information being indicative of an extensible authentication protocol method and indicative of a credential from the wireless terminal to use for authentication of the wireless terminal, the credential being indicative of a username and password credential; and
transmit, to the wireless terminal, a response to the GAS request from the wireless terminal, wherein the response includes the authentication information.
