Abstract: 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.

Abstract translation: 紧急呼叫者定位系统使用企业无线局域网（WLAN）定位系统来在紧急呼叫者上提供更准确的位置信息。 响应于用户发起紧急呼叫，蜂窝电话修改其WLAN标识符，例如其媒体接入控制（MAC）地址。 基于蜂窝网络已知的标识符，例如电话号码，订户名称，国际移动设备标识符（IMEI），国际移动用户标识符（IMSI）和/或国际电路卡标识符（ICCID）等来修改MAC地址。 。 蜂窝电话机还可以修改WLAN接口的探测定时器，以增强WLAN定位系统确定设备位置的能力。
