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.

According to some implementations of the present invention, RFID devices and middleware servers are automatically provisioned with a network address and with instructions for sending a request for a middleware server to a middleware server assigner. In some implementations, the middleware server assigner is a load balancer. In some implementations, a middleware server is associated with a plurality of RFID devices by associating a middleware server network address or names with the network addresses of the RFID devices. Preferred methods also provide for redundancy of middleware servers and dynamic re-assignment of RFID devices from an unavailable middleware server to an available middleware server.
