Mobile Device Wireless Identifier Assignment for Emergency Calls

摘要

An emergency caller location system uses enterprise Wireless Local Area Network (WLAN) location systems to provide more accurate location information on an emergency caller. A cellular telephone modifies its WLAN identifier, such as its Media Access Control (MAC) address, in response to a user initiating an emergency call. The MAC address is modified based on an identifier known to the cellular network, such as the phone number, subscriber name, International Mobile Equipment Identifier (IMEI), International Mobile Subscriber Identifier (IMSI), and/or International Circuit Card Identifier (ICCID). The cellular telephone may additionally modify the probe timer of the WLAN interface to enhance the ability of the WLAN location system to determine the location of the device.
