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.

Abstract: The present invention provides for a microwave radio communications user device arranged for communication with a base station and for receiving and decoding an MPDU for use in initial ranging signalling with said base station, the device being further arranged to retrieve data in a downlink-sub-frame from the base station serving to discriminate between MPDUs intended for different user devices.

Abstract: A microwave radio communications device is configured to communicate with a selected one of at least first and second base stations of respective first and second cells, the first cell having a greater area of coverage than the second cell. The device is configured to retrieve data from a BSID sent from each base station and serving to discriminate between signals from the said first and second base stations indicating the relative cell coverage. Thereby the device achieves selective registration to one of the base stations responsive to the said discrimination.
