Abstract: A wireless base station of a wireless mobile data communications system, such as a Mobile Data Base Station (MDBS) of a Cellular Digital Packet Data (CDPD) communications system, is configured. A packet, such as a frame relay frame, is communicated from a node of a packet data network to the wireless base station to configure the wireless base station to use a predetermined address, e.g., a Data Link Connection Identifier (DLCI), in the packet data network. The present invention may be implemented as methods, apparatus, and computer program products.

Abstract: The location of a mobile terminal is determined by receiving, at the mobile terminal, signals from at least three transmitters whose locations and transmit power levels are known. The strengths of the received signals are measured and then the location of the mobile terminal is determined based on the measured signal strengths and the locations and transmit power levels of the transmitters.

Abstract: The location of a mobile terminal is determined by receiving, at the mobile terminal, data packets from at least three transmitters whose locations are known. The delays for the data packets to travel from the transmitters to the mobile terminal are determined and then the location of the mobile terminal is determined based on the delays and the locations and of the transmitters.

Abstract: A wireless base station of a wireless mobile data communications system, such as a Mobile Data Base Station (MDBS) of a Cellular Digital Packet Data (CDPD) system, is configured. A port number and/or an internet address to be assigned to the wireless base station is determined. A datagram including the assigned port number and/or internet address is transmitted from a controller of the wireless mobile data communications system to the wireless base station via a backbone network of the wireless mobile data communications system. Responsive to receipt of the datagram at the wireless base station, the wireless base station is configured to accept datagrams addressed to the assigned port number and/or internet address. Related apparatus and computer program products are also described.
