Method for controlling access to an in-vehicle wireless network
First Claim
1. A method comprising:
- establishing communication with an in-vehicle router system (IVRS) by a portable device, the portable device communicating with the IVRS via a first communication link and a second communication link, wherein the established communication is maintained to facilitate;
transmitting, by a portable device located within a vehicle, a first token to a wireless access point (AP) associated with the IVRS, via a first communication link, to prompt the wireless AP to reply with a second token, the first communication link implementing a first protocol stack; and
receiving, by the portable device, the second token via the second communication link between the portable device and the IVRS, the second communication link implementing a second protocol stack different from the first protocol stack;
determining, by the portable device, whether the second token matches the first token; and
authenticating the wireless AP, by the portable device, only when the second token has been determined to match the first token.

Abstract
Disclosed is a technique for managing access by a portable device to an in-vehicle router system (IVRS). The IVRS determines network access privilege of the portable device located within the vehicle. The portable device determines whether it is connected to a wireless access point (AP) of the IVRS or a rogue network. The portable device transmits a first token to the wireless AP, via a first communication link implementing a first protocol stack, to prompt the wireless AP to reply with a second token. The portable device receives the second token via a second communication link implementing a second protocol stack different than the first protocol stack between the portable device and the IVRS. The portable device determines whether the second token matches the first token. If the second token is determined to match the first token, the portable device authenticates the wireless AP.

10. A method comprising:
-
establishing communication with a portable device by an in-vehicle router system (IVRS), the IVRS communicating with the portable device over a wireless local access network (WLAN) and a short range communication link, wherein communication by the portable device with the IVRS is limited to communication with an authentication subsystem of the IVRS, wherein the established communication is maintained to facilitate; transmitting, via the WLAN, a first token to the portable device; and receiving, via the short range communication link, a second token from the portable device; determining whether the first token matches the second token; and determining network access privilege of the portable device only when the first token has been determined to match the second token. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method comprising:
-
establishing, by a portable device within a vehicle, communication with a wireless access point (AP) associated with an in-vehicle router system (IVRS) of a vehicle, the portable device communicating with the IVRS over a wireless local access network (WLAN) and a short range communication link, the communication by the portable device with the IVRS being limited to communication with an authentication subsystem of the IVRS, wherein the established communication is maintained to facilitate; receiving, by the portable device via the WLAN, a first token, the first token having randomly generated data produced by the IVRS in response to the WLAN connection by the portable device; and transmitting, by the portable device via the short range communication link, the first token to the IVRS to prompt the IVRS to grant network access privilege to the portable device; transmitting, by the portable device, a second token via the short range communication link to the IVRS; and receiving, by the portable device, a third token via the WLAN from the IVRS; determining, by the portable device, whether the second token matches the third token; and authenticating the wireless AP, by the portable device, only when the second token has been determined to match the third token. - View Dependent Claims (23, 24, 25, 26)

27. An in-vehicle router system comprising:
-
a wireless access point (AP) configured to communicate with a portable device over a wireless local access network (WLAN); one or more near field communication (NFC) or wired communication devices configured to communicate with the portable device over a short range communication link; and at least one processor configured to; establish communication with the portable device via the wireless AP and the short range communication link, wherein communication with the in-vehicle router system is limited to an authentication subsystem of the in-vehicle router system, wherein the established communication is maintained to facilitate; transmit by the wireless AP, via the WLAN, a first token to the portable device, wherein the first token is produced by a random or pseudo-random generator; and receive, via the short range communication link, a second token from the portable device; determine whether the first token matches the second token; and determine network access privilege of the portable device only when the first token has been determined to match the second token. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
