An illustrative embodiment of the present invention comprises: receiving uplink analog RF signals at a base station; converting the uplink analog wide-band RF signals into IF uplink digital signals at an analog-to-digital converter; converting the IF uplink digital signals into a number of uplink channels; and demodulating selected narrow-band uplink channels from the total number of narrow-band uplink channels.

Abstract: An apparatus and method for disabling wireless communication devices establishes a disabling zone. Inside the disabling zone, one or more capabilities of the wireless communication devices are disabled. The wireless communication devices may include cellular phones, beepers, pagers, portable computers, electronic personal attendants, and/or similar wireless devices. In a first embodiment, the zone is formed in conjunction with a power monitoring unit proximate the zone. In a second embodiment, the zone is formed in conjunction with a position monitoring system determining the geographical position of the wireless communication devices. In both the first and second embodiments, the zone may be either geographically fixed or moveable.

Abstract: A technique for identifying a geographical location of a mobile terminal which includes receiving a set of characteristics from the mobile terminal, comparing the set of characteristics from the mobile terminal with a set of attributes for each of the cells, and identifying one of the sub-cells whose attributes most closely match the characteristics from the mobile terminal as the sub-cell in which the mobile terminal located. The attributes may include discrete RF attributes, such as average pilot strength, chip offset, or pilot strength. The attributes may also include continuous features, such as signature waveforms.

Abstract: A fuzzy-logic based overload control for packet switches wherein a distribution curve is developed regarding the overload possibility versus receive packet stream processing rate. The transmit packet stream is measured and a processing rate of the receive packet stream is measured. An overload possibility value is manipulated according to the measured bursts of the transmit packet stream and a location on the distribution curve of the measured processing rate. Packets are dropped from the transmit stream if the overload possibility value is above a threshold.

Abstract: A method and system for controlling down link transmit power during a soft hand-off in a spread-spectrum wireless system supports independent power control of multiple forward channels to reduce fading. For a soft hand-off, a mobile switching center determines if a forward control channel is transmitted from different sectors of base stations than a forward data channel is. The base stations preferably adjust transmit powers of the forward channels grouped into different physical channels by receiving power control data over the allocated reverse power control channels to compensate for fading of the forward channels during a soft hand-off.

Abstract: Apparatus for transferring packet data incorporates a “hand-off” feature that allows the transfer of an existing PPP connection from one packet server to another packet server. Such a hand-off control message or call continue transaction can be initiated by any of the servers involved in the transactions. For instance, assume an initial arrangement where a point-to-point call is set up and in progress between a user and a private network via a first packet server (e.g., a first Serving LAC) and a second packet server (e.g., an Anchor LAC). If, for example, the user moves out of the region served by the first packet server into a region served by a third packet server (e.g., a second Serving LAC), then a hand-off control message transaction, according to the invention, is initiated. Either the second Serving LAC or the Anchor LAC may initiate the call continue transaction.

Abstract: A wireless communications system and method is disclosed. A cell has a plurality of allocated sectors and a base station that communicates with mobile units contained within the cell. The base station has a transmitter that transmits communication signals along at least two carriers per sector within a cell. Each carrier within a sector is assigned a zone spaced from the base station, such as from an inner zone to an outer zone. The power per carrier is reduced successively from the outer to the inner zone.

Abstract: Disclosed are silica structure crack detection methods and apparatuses particularly useful in sol-gel fabrication processes.

Sensing may be by active or passive techniques and may include contact and non-contact methods of monitoring.

Abstract: A DPRAM is placed in the RF path before the digital to analog converter, to provide dynamic path gain compensation to the digital signal prior to conversion to an analog signal. The DPRAM stores corrections to the signal to compensate for amplitude losses in the signal arising from heat and non-linearities. The DPRAM has two sets of identical addresses. A logic switch, alternately directs an input signal to one of the two sets of addresses. Pre-calculated signal values which compensate for path gain are stored in one of the two sets of addresses in the DPRAM. The signal Input to the DPRAM is directed to the other block. The value of the signal input to the DPRAM will determine the address to which the new value can be found. It is this new value which is actually input to the DAC and from which an analog signal is created.

Abstract: An apparatus for alerting a user at an alerting device that data has been delivered to a wireless communication device includes an adapter that receives a data receipt signal from the communication device and activates an associated alerting device after verifying its identify. Verifying the identity of the alerting device includes comparing an alerting device identifier, which is either stored or delivered to the alerting device from a remote location, with a communication device identifier that is embedded or otherwise included with the data that is delivered to the associated communication device. The alerting device is activated if the comparison shows that the alerting device is that which corresponds to the communication device that received the data. Alerting devices may be incorporated into jewelry, garments releasable straps and other objects that are convenient for the user.

Abstract: This invention relates to methods and apparatus for handling incoming or intra-office calls when a telephone subscriber having a POTS, (Plain Old Telephone Service) telephone instrument and line connecting that customer to a serving switch, is connected to an Internet service provider for providing communications to the Internet. The bandwidth of the customer's line is divided into a lower band for providing communications, and a higher band for transmitting signaling and control information. When an incoming or intra-office call is received while the customer is connected to the Internet, the signal channel is used to transmit information which can be displayed to the called customer providing information about the call. If the called customer wishes to answer the call, the called customer can signal over the signaling channel a request that the incoming or intra-office call be completed.

Abstract: The system and method of the invention automatically provide appropriate configuration and control software to a hardware system consisting of multiple target hardware modules. A system controller is connected to the target hardware modules and to a repository that stores a set of software modules. Each software module includes configuration and control information for a particular target hardware module. When a particular software control and configuration scheme for at least a portion of the target hardware modules is to be implemented in the hardware system, software modules corresponding to the particular software control and configuration scheme are selected and associated with a system definition file that is also stored in the repository. When the system definition file is invoked by the system controller, the system controller executes the associated software modules thereby providing the particular software control and configuration scheme to appropriate target hardware modules.

Abstract: A mobile-station with an integrated user identity module (I-UIM) and a removable user identity module (R-UIM) that adheres to the second generation standard intersystem protocol for validation and authentication is disclosed herein. The I-UIM includes an integrated electronic serial number (I-ESN) and integrate-subscriber/subscription information, whereas the R-UIM includes a removable electronic serial number (R-ESN) and remote-subscriber/subscription information. The mobile-station will transmit either the I-UIM and integrated subscriber/subscription information pair or the R-UIM and remote subscriber/subscription information pair depending on the user of the mobile-station. A registry of I-ESNs paired with integrated-subscriber/subscription information and R-ESNs paired with remote-subscriber/subscription information will be maintained by wireless communications systems and/or authentication centers.

Abstract: Parallel-formatted information is selectively removed and inserted in a wavelength division multiplexed network by transporting the parallel-formatted information using selected wavelength channels in a wavelength division multiplexed signal as a parallel bus (a “wavelength bus”) and by selectively adding and dropping only information in the wavelength bus at an add/drop node. In one illustrative embodiment, one or more wavelength channels in a wavelength division multiplexed signal are allocated to form a wavelength bus for carrying multiplexed information supplied by one or more sources in a parallel format. At an add/drop node in the network, the wavelength channels in the wavelength bus are separated from the wavelength division multiplexed signal and information to be dropped is selectively removed by demultiplexing the parallel-formatted information.

Abstract: The configuration control system is implemented in an environment of multiple hardware platforms and operating systems and can be used to control hardware, software, data and system abstractions. The configuration control system gives the appearance of a unified maintenance environment even though it is controlling hardware and software from many vendors with multiple maintenance environments. It is designed to control the configuration of any system where there are dependencies among subsystems and loss of a subsystem has the potential to interrupt service. The maintenance configuration control protocol unifies Configuration Control to allow any subsystem to communicate with any other subsystem and to the user interface using a common messaging interface. It creates a common state model, relationship model, behavior model and request/response messaging interface for all subsystems whether they are hardware, software, or an abstraction.

Abstract: A technique for bridging the gap between an initial call and a return call by using network capabilities to capture the caller's information and by providing efficacious means for reaching the caller at a later time. The subscribed user, i.e., the called party, is provided with an opportunity to access a self-generating return call list which stores the names and the telephone numbers of the callers who could not speak to the subscribed user e.g., the subscribed user was not available to answer within a predetermined number of rings or was busy with another call. In addition, the system may be configured to create entries in the return call list for all incoming calls to the subscribed user, irrespective of whether the incoming calls were answered or not. The subscribed user may at any time access the return call list, either from his own telephone or some other DTMF telephone set.

Abstract: An improved method of updating parameters stored in memory of mobile telecommunications stations. An object model represents all the parameters that can be modified in an IS-683A mobile station. The details of the physical location of each parameter are defined in this mobile object model. Advantageously, when any parameter is changed or added, it is necessary to provide the computer system, which generates messages to be transmitted to the mobile station, only the identification and value of the parameter to be added or changed. The computer system then generates a message sequence that defines the memory location in the mobile station to be changed, and the new value of the data for that memory location. Advantageously, this arrangement sharply reduces the total number of airwave messages transmitted to the mobile station in order to change or add a parameter.

Abstract: Disclosed is a method and apparatus to increase convection heat transfer in an electrical system. The increase in convection heat transfer is achieved by applying a heat source in the vicinity of an electronic element. This effectively increases the amount of airflow across the electronic element.

Abstract: The synchronization system uses a TDMA or AMPS air interface to provide timing synchronization between previously unsynchronized base stations. The synchronization of base stations is critical between when determining the geographical position of a mobile because the geographical position is determined using a time difference of arrival method. In order to synchronize a remote base station with a serving base station, the remote base station receives a signal from the serving base station and measuring the receiving time of the signal at the remote base station in relation to the clock of the remote base station. The synchronization system determines the transmission time of the signal based on the reception time of the signal and the distance between the base stations, in relation to the clock signal of the second station, and synchronizes the clock of the remote base station to the clock of the serving base station based on the offset in the clock cycles at the time the signal was transmitted.
