Address assignment for initial authentication
A mobile device may transition between Extended Service Set (“ESS”) networks while maintaining the same internet protocol (“IP”) address while transitioning. The transition may occur seamlessly, such that a consumer never loses the network connection despite transitioning between networks. The mobile device may receive an IP address from a pool of addresses, such that the mobile device can keep that IP address as it is transitions between networks that each have access to the pool. The assignment of the IP address to the mobile device is from the pool of IP addresses rather than from the AP.
1. A method performed by a mobile device, comprising:
requesting a connection with a first Extended Service Set (ESS) wireless network;
receiving an internet protocol (IP) address from the first ESS wireless network after requesting the connection with the first ESS wireless network, wherein the IP address is received from a server with IP addresses that are available through both the first ESS wireless network and a second ESS wireless network;
receiving, from the first ESS wireless network using Access Network Query Protocol (ANQP) prior to associating with the first ESS wireless network, an indication of support for transitioning to different ESS wireless networks while maintaining the IP address; and
transitioning from the first ESS wireless network to the second ESS wireless network while maintaining the IP address.
2. The method of claim 1 , wherein the indication is carried in an extended capability bit.
3. The method of claim 1 , further comprising:
terminating the connection with the first ESS wireless network; and
connecting with the second ESS wireless network using the IP address.
4. The method of claim 1 , wherein transitioning from the first ESS wireless network to the second ESS wireless network is expedited when the IP address does not change during transition from the first ESS wireless network to the second ESS wireless network.
5. The method of claim 1 , wherein receiving the IP address and transitioning from the first ESS wireless network to the second ESS wireless network are based on Link Control Protocol (“LCP”).
6. The method of claim 1 , further comprising connecting with the second ESS wireless network while maintaining the IP address.
7. The method of claim 1 , further comprising transmitting a message indicating an ability to transition between ESSs prior to associating with the first ESS wireless network.
8. The method of claim 1 , further comprising transitioning to the second ESS wireless network from the first ESS wireless network.
9. The method of claim 1 , further comprising:
receiving a first request for an address from a first wireless local area network (WLAN); and
assigning the address from a server of available IP addresses to facilitate a connection with the first WLAN, wherein the address is used to transition from the first WLAN to a second WLAN when the first WLAN and the second WLAN both receive IP addresses from the server of available IP addresses.
10. A system for transitioning between Extended Service Set (ESS) wireless networks, wherein the system comprises:
a mobile device configured to:
transmit a request for a connection with a first ESS wireless network;
receive an internet protocol (IP) address from the first ESS wireless network subsequent to transmission of the request for the connection with the first ESS wireless network, wherein the IP address is received from a server with IP addresses that are available through both the first ESS wireless network and a second ESS wireless network;
receive, from the first ESS wireless network using Access Network Query Protocol (ANQP) prior to associating with the first ESS wireless network, an indication of support for transitioning to different ESS wireless networks while maintaining the IP address; and
transition from the first ESS wireless network to the second ESS wireless network while maintaining the IP address.
11. The system of claim 10 , wherein the indication is carried in an extended capability bit.
12. The system of claim 10 , wherein the mobile device is further configured to:
terminate the connection with the first ESS wireless network; and
connect with the second ESS wireless network using the IP address.
13. The system of claim 10 , wherein the mobile device is further configured to receive the IP address and transition from the first ESS wireless network to the second ESS wireless network using Link Control Protocol (“LCP”).
14. The system of claim 10 , wherein the mobile device is further configured to transmit a message indicating an ability to transition between ESSs prior to associating with the first ESS wireless network.
15. A non-transitory computer-readable medium configured to store a computer program product comprising computer executable instructions that, when executed by a processor of a mobile device, cause the processor to be configured to:
transmit a request for a connection with a first Extended Service Set (ESS) wireless network;
receive an internet protocol (IP) address from the first ESS wireless network subsequent to transmission of the request for the connection with the first ESS wireless network, wherein the IP address is received from a server with IP addresses that are available through both the first ESS wireless network and a second ESS wireless network;
receive, from the first ESS wireless network using Access Network Query Protocol (ANQP) prior to associating with the first ESS wireless network, an indication of support for transitioning to different ESS wireless networks while maintaining the IP address; and
transition from the first ESS wireless network to the second ESS wireless network while maintaining the IP address.
16. The non-transitory computer-readable medium of claim 15 , wherein the indication is carried in an extended capability bit.
17. The non-transitory computer-readable medium of claim 15 , wherein the computer executable instructions further cause the processor to be configured to:
terminate the connection with the first ESS wireless network; and
connect with the second ESS wireless network using the IP address.
18. The non-transitory computer-readable medium of claim 15 , wherein the computer executable instructions further cause the processor to be configured to receive the IP address and transition from the first ESS wireless network to the second ESS wireless network using Link Control Protocol (“LCP”).
19. The non-transitory computer-readable medium of claim 15 , wherein the computer executable instructions further cause the processor to be configured to connect with the second ESS wireless network while maintaining the IP address.
20. The non-transitory computer-readable medium of claim 15 , wherein the computer executable instructions further cause the processor to be configured to transmit a message indicating an ability to transition between ESSs prior to associating with the first ESS wireless network.
