METHOD OF LIMITING USE OF A MOBILE WIRELESS ACCESS POINT NEAR A WIRELESS LOCAL AREA NETWORK
First Claim
1. A mobile communication device comprising a processor and memory, the mobile communication device operable as a mobile wireless access point, the memory storing software that, upon execution by said processor, causes the processor to:
- read from said memory a wireless local area network (WLAN) identifier that is known to be used by a WLAN;
read from said memory an indication of a channel on which a wireless access point of said WLAN is known to operate, the channel having an associated center frequency;
monitor only the channel for a transmission of the WLAN identifier, the transmission, if detected, indicating that the mobile communication device is within the WLAN; and
upon detection of the transmission, prevent the mobile wireless access point at the mobile communication device from using the WLAN identifier.

Abstract
To promote network security in a wireless local area network (WLAN), a mobile communication device, which is operable as a mobile wireless access point, may read a WLAN identifier that is known to be used by the WLAN and an indication of a channel on which a wireless access point of the WLAN is known to operate. The device may then monitor the channel for a transmission of the WLAN identifier. The mobile wireless access point may be configured to operate using the selected channel so that the monitoring occurs on the same channel as that on which the mobile wireless access point is operating. The transmission, if detected, may be considered to indicate that the mobile communication device is within the WLAN. Upon detecting the transmission, use of the WLAN identifier by the mobile wireless access point at the mobile communication device may be prevented, e.g. by requiring the mobile wireless access point to use a different WLAN identifier or by disabling the mobile wireless access point.
