Mobile WLAN gateway
A technique for operating a mobile station as wireless local-area network [“WLAN”] gateway. The mobile station is provided with a gateway application to control the following operations: activating ( 3 - 0 ) the WLAN means as a WLAN base station capable of communicating with at least one WLAN terminal over a WLAN network; creating a network identifier ( 3 - 2, 3 - 4 ) for the WLAN base station; assigning ( 3 - 8, 3 - 10 ) an internet protocol address for the at least one WLAN terminal; resolving domain name service [“DNS”] queries ( 3 - 12 . . . 3 - 18 ) in cooperation with an external DNS service system; assigning at least one port number for each protocol supported by the gateway application; and tunneling internet traffic ( 3 - 30 . . . 3 - 36 ) between the at least one WLAN terminal and an internet host over the broadband connection.
1. A mobile station comprising:
a memory;
a processor;
a radio transceiver configured to establish and maintain a broadband connection with a mobile communication network;
a user interface comprising an input section and an output section;
wireless local-area network (WLAN) means having a first mode of usage acting as a WLAN client, and a second mode of usage acting as a WLAN base station capable of communicating with at least one WLAN terminal over a WLAN network;
the WLAN means responsive to an activation or deactivation command according to a setting received via the input section of the user interface;
some code portions stored in the memory and executed by the processor to:
assign at least one port number for each protocol supported by a gateway application;
tunnel internet traffic between the at least one WLAN terminal and an internet host over the broadband connection when the second mode of the WLAN means is activated; and
deactivate the second mode of the WLAN means in response to a detected absence of WLAN terminal activity for a predetermined period of time.
2. The mobile station according to claim 1 , further comprising means for downloading and executing the code portions.
3. The mobile station according to claim 1 , wherein the code portions are further executed by the processor to redirect a first HTTP page request from each mobile station during an internet session to a predetermined internet address.
4. The mobile station according to claim 1 , wherein the mobile station comprises means for determining a location of the mobile station and the code portions are further executed by the processor to associate the determined location to the tunnelled internet traffic.
5. The mobile station according to claim 4 , wherein the code portions are further executed by the processor to provide one or more additional services to the WLAN terminal based on the determined location.
6. The mobile station according to claim 1 , wherein the code portions are further executed by the processor to collect traffic statistics for the tunnelled traffic and for transmitting at least a portion of the collected traffic statistics to a supplementary server.
7. A mobile station according to claim 1 , wherein the code portions are further executed by the processor periodically or in response to a detected activity of the at least one WLAN terminal.
8. A method for operating a mobile station, the mobile comprises a WLAN means having a first mode of usage acting as a WLAN client, and a second mode of usage acting as a WLAN base station capable of communicating with at least one WLAN terminal over a WLAN network; the WLAN means responsive to an activation or deactivation command according to a setting received via the input section of the user interface;
the method comprising:
activating a second mode of WLAN means having a first mode of usage acting as a WLAN client of usage acting as a WLAN base station capable of communicating with at least one WLAN terminal over a WLAN network;
assign at least one port number for each protocol supported by a gateway application;
tunnelling internet traffic between the at least one WLAN terminal and an internet host over the broadband connection when the second mode of the WLAN means is activated; and
deactivating the second mode of the WLAN means in response to a detected absence of WLAN terminal activity for a predetermined period of time.
9. A non-transitory computer readable medium having embodied thereon a program, the program being executable by a processor to perform a method for operating a mobile station, the method comprising:
activating a second mode of the WLAN means having a first mode of usage acting as a WLAN client of usage acting as a WLAN base station capable of communicating with at least one WLAN terminal over a WLAN network;
assign at least one port number for each protocol supported by a gateway application;
tunnelling internet traffic between the at least one WLAN terminal and an internet host over the broadband connection when the second mode of the WLAN means is activated; and
deactivating the second mode of the WLAN means in response to a detected absence of WLAN terminal activity for a predetermined period of time.
10. The non-transitory computer readable medium according to claim 9 , wherein the program is executable by the processor periodically or in response to a detected activity of the at least one WLAN terminal.
