Methods and apparatus to discover authentication information in a wireless networking environment
View Patent ↗Examples to discover network authentication information in a wireless network involve transmitting during network discovery and prior to authentication, a Generic Advertisement Service (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 discover authentication information in a wireless network, the method comprising:
transmitting, from a wireless terminal, during network discovery and prior to authentication, a Generic Advertisement Services (GAS) request to a network access point, the GAS request requesting authentication information, the authentication information being indicative of an extensible authentication protocol method and indicative of a credential required from a wireless terminal to use for authentication of the wireless terminal, the credential being indicative of a username and password credential; and
receiving, by the wireless terminal, a response to the GAS request from the network access point, wherein the response includes the authentication information.
2. The method of claim 1 , wherein the credential is obtainable by the wireless terminal.
3. The method of claim 1 , wherein the wireless terminal is a mobile communication device.
4. The method of claim 1 , wherein the response includes second authentication information.
5. A method to discover network authentication information in a wireless network, the method comprising:
transmitting, from a wireless terminal, during network discovery and prior to authentication, a Generic Advertisement Service (GAS) request to a network access point, the GAS request requesting network authentication information;
receiving, by the wireless terminal, a response to the GAS request from the network access point; and retrieving from the response, the network authentication information, wherein the network authentication information includes an authentication type information,
wherein the authentication type information indicates that the wireless terminal performs at least one of: (a) on-line login enrollment, or (b) domain name server (DNS) redirection.
6. The method of claim 5 , wherein the wireless terminal is a mobile communication device.
7. The method of claim 5 , wherein the authentication type information is associated with an identifier of value 260.
8. The method of claim 5 , wherein the network authentication information includes second authentication type information.
9. A method to discover network authentication information in a wireless network, the method comprising:
transmitting, from a wireless terminal, during network discovery and prior to authentication, a Generic Advertisement Service (GAS) request to a network access point, the GAS request requesting network authentication information;
receiving, by the wireless terminal, a response to the GAS request from the network access point; and retrieving from the response, the network authentication information, wherein the network authentication information includes an authentication type information and a re-direct uniform resource locator (URL) field, wherein the authentication type information indicates that the wireless terminal uses the re-direct URL field to perform at least one of: (a) acceptance of terms and conditions, or (b) hyper text transfer protocol (HTTP)/ hyper text transfer protocol secure (HTTPS) redirection.
10. The method of claim 9 , wherein the network authentication information includes a re-direct URL length field.
11. The method of claim 9 , wherein the wireless terminal is a mobile communication device.
12. The method of claim 9 , wherein the authentication type information is associated with an identifier of value 260.
13. The method of claim 9 , wherein the network authentication information includes second authentication type information and a re-direct uniform resource locator (URL) field.
14. A method to provide network authentication information in a wireless network, the method comprising:
receiving, by a network 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 network 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,
wherein the authentication type information indicates that the wireless terminal performs at least one of: (a) on-line login enrollment, or (b) domain name server (DNS) redirection.
15. The method of claim 14 , wherein the wireless terminal is a mobile communication device.
16. The method of claim 14 , wherein the authentication type information is associated with an identifier of value 260.
17. The method of claim 14 , wherein the network authentication information includes second authentication type information.
