Abstract: A method and system provides for the automated handling of alarms from a fault management system for a telecommunications network without the need for the intervention of an operator. When the fault management system identifies service outages or other network performance problems, an alarm is generated, and an established set of rules is applied to evaluate the alarm based on certain attributes of the alarm. From this application of the rules, an action is identified and initiated, which could involve any of a number of tasks or activities, including, for example, transmission of instructions directly to a network device, electronic notifications directly to a technician or other maintenance personnel, and/or generation of a trouble ticket.

Abstract: A simple block coding arrangement is created with symbols transmitted over a plurality of transmit channels, in connection with coding that comprises only of simple arithmetic operations, such as negation and conjugation. The diversity created by the transmitter utilizes space diversity and either time or frequency diversity. Space diversity is effected by redundantly transmitting over a plurality of antennas, time diversity is effected by redundantly transmitting at different times, and frequency diversity is effected by redundantly transmitting at different frequencies. Illustratively, using two transmit antennas and a single receive antenna, one of the disclosed embodiments provides the same diversity gain as the maximal-ratio receiver combining (MRRC) scheme with one transmit antenna and two receive antennas.

Abstract: A discrete multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT). This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment.

Abstract: Call data collected from the switch at a Mobile Telephone Switching Office is combined with location information of a mobile unit to generate information reports concerning the electromagnetic coverage of a geographic region. The collection of call data from the switch permits consideration of uplink information in the analysis of system performance.

Abstract: A method and system of erasing at least part of the location information stored on a subscriber identity module (SIM) of a mobile phone. The SIM stores the most recently used service provider in its location information. Either at power down or power up, the location information is erased so during the power up routine, the service provider search schedule will not find a service provider when it first searches the most recently used service provider stored in the location information. In this case, the service provider search routine will appropriately choose either the home service provider or a preferred service provider rather than the service provider stored in the location information. The method of erasing at least part of the location information may be carried out by a program stored on the SIM card or by a wireless network transmitting an instructive signal to the wireless device.

Abstract: An intelligent interface provides a non-dedicated wireless communications path for reporting alarm events from a landline-based alarm system to a remote monitoring system. The intelligent interface includes a cradle for a cellular handset or other wireless device, and a network connector (such as an RJ31X jack) between an alarm system control panel and the PSTN. When a wireless device is present in the cradle, the intelligent interface bypasses the landline and routes all security calls from the alarm system control panel through an analog-to-digital digital signal processor and to the wireless device, which places a call to the remote monitoring center. When no wireless device is present, the intelligent interface allows the alarm system control panel to seize the landline to place the security call.
