Method and apparatus for loading a landing page
View Patent ↗A Universal Serial Bus (USB) modem/Wireless Wide Area Network (WWAN) device is provided that when connected to a host device, presents itself as an Ethernet endpoint to the host device, without requiring additional software/drivers to be downloaded to the host device. Embedded in the USB modem/WWAN device are various modules that provide functionality allowing either automatic connection to the Internet or redirection to a local Web User Interface (UI) that a user may employ to configure the USB modem/WWAN device and/or manually connect to the Internet. Additionally, the USB modem/WWAN device employs predetermined rules to determine whether or not/how the redirection occurs, including in scenarios where wireless connectivity to the Internet is unavailable.
1. A method, comprising:
presenting a Wireless Wide Area Network (WWAN) modem to a host device as an Ethernet endpoint without installing WWAN modem application software on the host device, wherein the presenting is performed by the WWAN modem itself;
issuing to the host device, from the WWAN modem, an Internet Protocol (IP) address;
automatically connecting to the Internet when the WWAM modem determines that it is configured to automatically connect to the Internet; and
redirecting a hypertext protocol (HTTP) request from the host device to a Web user interface (UI) when the WWAN modem determines that it is not configured to automatically connect to the Internet.
2. The method of claim 1 , wherein the IP address comprises a private IP address, and wherein the private IP address is issued via a Dynamic Host Configuration Protocol (DHCP) server resident on the WWAN modem.
3. The method of claim 2 further comprising, when connectivity to the Internet via a wireless carrier network is unavailable, performing at least the following:
receiving a DNS query from the host device;
assigning the host device a local DNS server-assigned IP address instead of the private IP address issued by the DHCP server;
caching a host device name and the DNS server-assigned IP address, and performing the redirecting to the Web UI, wherein the Web UI comprises a landing page; and
upon establishment of the connectivity to the wireless carrier network, further performing at least the following:
further caching a real IP address associated with the HTTP request; and
upon receipt of a second HTTP request from the host device, forwarding the second HTTP request to the real IP address.
4. The method of claim 2 further comprising, when connectivity to the Internet via a wireless carrier network is unavailable, performing at least the following:
receiving a DNS query from the host device;
assigning the host device a local DNS server-assigned IP address instead of the private IP address issued by the DHCP server;
performing the redirecting to the Web UI, wherein the Web UI comprises a landing page; and
upon establishment of the connectivity to the wireless carrier network, and upon receipt of a second HTTP request, forwarding the second HTTP request to a proxy server, wherein the proxy server fetches a proper HTTP page.
5. The method of claim 1 , wherein the Web UI is hosted on a Web server resident on the WWAN modem, and wherein the Web UI provides for manual connection to the Internet or configuration of the WWAN modem.
6. The method of claim 1 , wherein the Ethernet endpoint comprises one of an RMNet Ethernet endpoint or a communications device class (CDC) Ethernet Network Control Model (ECM) Ethernet endpoint.
7. The method of claim 1 , further comprising applying at least one predetermined rule prior to the redirecting to determine whether the redirecting should occur.
8. The method of claim 1 , wherein the redirecting is effectuated via a domain name system (DNS) relay resident on the WWAN modem.
9. The method of claim 1 further comprising, bypassing the redirection upon determining that the HTTP request is non-Web browser related.
10. The method of claim 1 , wherein the WWAN modem comprises, in part, a Wireless Wide Area Network (WWAN) router configured to route traffic to the Internet.
