Abstract
The present invention relates to a method and system for providing access to the emergency services over a network, particularly a WiMAX network. The method comprises the steps of identifying when a user device (51) sends a signal to the WiMAX network (52, 53, 54) requesting access to an emergency service; detecting a network address of the nearest emergency service communication device to the user device; relaying a signal (ES-SERV-RSP) via the WiMAX network to the user device containing the network address of the nearest emergency service communication device; and establishing at least one Service Flow between the WiMAX network and the user device to allow data to be exchanged between the user device and the emergency service communication device.
