Method of providing a guest terminal with emergency access to a WLAN
First Claim
1. A method of providing a terminal with an emergency access over a WLAN to a LAN comprising one or more access points and an access control function which admits data packets from users of the WLAN associated with a first SSID to the LAN, whereby the method comprises the steps of:
- defining one or more emergency SSIDs dedicated to allow access to the LAN in an emergency case;
initiating an emergency call by sending data packets from a terminal associated with a selected emergency SSID to one of the one or more access points;
admitting, by the access control function, the data packets from the terminal associated with the selected emergency SSID to the LAN; and
routing the data packets associated with the selected emergency SSID, after admission to the LAN, to an emergency answering point.

Abstract
The invention concerns a method of providing a terminal (10) with an emergency access over a WLAN (2) to a LAN (3), and a communication system (1) to execute this method. The LAN (3) comprises one or more access points (20) and an access control function (21) which admits data packets from users of the WLAN (2) associated with a first SSID to the LAN (3). One or more emergency SSIDs dedicated to allow access to the LAN (3) in an emergency case are defined. An emergency call is initiated by sending data packets from the terminal (10) associated with a selected emergency SSID to one of the one or more access points (20). The access control function (21) admits the data packets from the terminal (10) associated with the selected emergency SSID to the LAN (3). The data packets from the terminal (10) associated with the selected emergency SSID are routed, after admission to the LAN (3), to an emergency answering point (60).
