Abstract: A wideband code division multiple access (CDMA) communication system overlayed on an IS-95 network generates two or more digital bit streams from a group of wideband digital data streams, each digital bit stream spread to form a CDMA component signal. Each CDMA component signal is combined with a corresponding IS-95 digital bit stream to form a composite CDMA signal, allowing a base station to share transmitter subsystems between the wideband and IS-95 systems. For up to three carrier frequencies, up to three composite CDMA signals are employed. A digital bit stream for a group of summed user conversations in the IS-95 system modulates a respective RF carrier frequency to generate a low-power RF signal. The CDMA component signals of the wideband CDMA system are generated so each has a chip rate identical to the chip rate of the digital bit streams of the IS-95 system.

Abstract: A method, device, and software, for monitoring whether use of a packetized network is commensurate with a preexisting transport service election designated for a user, is disclosed. Also, a method, device and software for selectively discouraging such non-compliant use is disclosed. Packets associated with a user are received and at least one parameter of the packets or an absence of such a parameter, which is indicative of a transport service required by the packets, is inspected. Packets for which the required transport service does not comply with the preexisting service election are identified. If desired, the arrival of the non-compliant packets is selectively delayed by a duration sufficient to degrade the quality of the non-compliant use, which discourages similar non-compliant use. The one or more parameters or absence thereof of the received packets correspond to particular fields within the packet that are indicative of the transport service required by the packet.

Abstract: In a wireless communication system, the constellation mapping scheme employed may be changed on a per-time-slot basis, i.e., from time slot to time slot, so that the constellation used to encode the symbols of each time slot may be different for each time slot within a single frame and may be different for a particular time slot in different consecutive frames. In other words, several constellation mapping schemes are available, with each providing the ability to transmit a different number of bits per symbol, and the particular constellation mapping scheme employed for any time slot need be selected for that time slot only. The ability to use any particular constellation mapping scheme is dependent on the current channel quality. The particular constellation mapping used for the user data of the time slot may be indicated in the preamble of the time slot.

The cutting tool has a blade assembly supported inside a housing on a pair of cams. A coaxial cable is inserted into the cutting tool and the housing is rotated about the cable to push the blade assembly along spiral tracks in the cams. According to one embodiment of the invention, the blade assembly has three blades, each blade sized and positioned to make a cut of the corresponding appropriate depth in the coaxial cable thereby forming the desired stepped cable end. Cutting tools of the invention may be adapted for preparation of large-diameter (e.g., over 1 inch) coaxial cables.

Abstract: Apparatus and processes for downloading data corresponding to forwarding information, e.g., a forwarding telephone number, from either a central office or from the telephone of a called party. In one embodiment, a central office downloads data corresponding to forwarding information to a calling party using, e.g., FSK signaling techniques. The calling party preferably receives the downloaded data corresponding to the forwarding information using a call information detector/receiver, e.g., a Caller ID receiver. In another embodiment, the telephone corresponding to a called party answers the incoming call and downloads data to the calling party relating to forwarding information, e.g., a forwarding telephone number. Preferably, the data is transmitted from the called party to the calling party after the called telephone answers the call using DTMF tone encoding techniques.

Abstract: A method and apparatus for performing real-time endpoint detection for use in automatic speech recognition. A filter is applied to the input speech signal and the filter output is then evaluated with use of a state transition diagram (i.e., a finite state machine). The filter is advantageously designed in light of several criteria in order to increase the accuracy and robustness of detection. The state transition diagram advantageously has three states. The endpoints which are detected may then be advantageously applied to the problem of energy normalization of the speech portion of the signal.

Abstract: A telecommunications network(10) having a distributive network management system(20) for remotely managing the plurality of network elements(38) has a management computer, or work station(22) with a management program communicating through the Internet by via managed object commands. An element management server(24) communicates through the computer Internet with the plurality of network elements(38) via a simplified network management protocol, or SNMP, to communicate management information concerning the plurality of network elements(38). The managed objects are responsive to managed object commands from the management computer(22) to provide the management information to the management program and to take actions as directed. Commands are composed in EMAPI notation to render them independent of any protocol used between the element manager server(24) and the managed network elements(38). Communications between the management computer(22) and the element manager server(24) utilizes CORBA.

Abstract: A method is provided for transmission of packets (102) as a sequence of data packets (104). A redundancy or check word (106) is composed for each packet of the sequence of data packets. A transmission packet is composed of a packet, a check word of a prior packet in the sequence of packets, and a check word of a subsequent packet in the sequence of packets. The transmission packets are transmitted in a sequence and received in a sequence. After reception, the transmission packets are separated so that the packets are compared with the corresponding check words transmitted with adjacent packets in the sequence.

According to the various methods, the antennas can be designed, installed and operated so as to provide improved information capacity based on the diffusive, polarization and multi-path nature of the environment in which they operate.

Abstract: A communication system utilizes an open system network protocol, such as the Transmission Control Protocol/Internet Protocol (TCP/IP), to transport Intelligent Network signaling messages from an SS7 network to a service provider which is not directly linked to the SS7 network. A gateway/bridge is provided between the SS7 network and a network which operates in accordance with an Internet protocol to transform Internet protocol messages, such as TCP/IP format messages, into SS7 format, and vice versa. In this way, an Internet protocol network may be used to transport Intelligent Network signaling messages between an SS7 network and a non-SS7 network service provider.

Abstract: A method and system for providing configurable data services for mobile stations allows mobile stations to select the type and content of data messages addressed to a mobile station. The method includes establishing an active profile associated with a corresponding mobile station. A wireless data server receives a data message addressed to the mobile station. The active profile for the mobile station is accessed to determine applicable stored profile attributes for the mobile station to which the received data message is addressed. The wireless data server detects received profile attributes associated with the received data message. Filtering is applied to the received data message in real-time based on a comparison between the detected profile attributes and the stored profile attributes. The detected profile attributes are readily standardized in accordance with standards followed by the content service provider in order to gain access to the mobile service subscribers.

Abstract: Received symbols are decoded in a communication system using a maximum likelihood block noncoherent decoding algorithm. The noncoherent decoding algorithm utilizes a set of test words determined for a given block of symbols based on a corresponding set of crossover angles which specify transitions between the test words. Advantageously, the decoding algorithm provides exact maximum likelihood block decoding having a complexity which is independent of the data rate of the symbols and linear-logarithmic in the block length.

Abstract: A tunable microlens is disclosed that having a substrate with a non-zero radius of curvature in a way such that the microlens is able to achieve a new directional view without manual repositioning. The directional view of the microlens is altered by applying a voltage to at least one of a plurality of electrodes and thereby causing a voltage differential between the at least one of a plurality of electrodes and a conducting droplet of liquid disposed on the substrate with a non-zero radius of curvature. As the droplet moves to a different point along the surface of the substrate having a non-zero radius of curvature, the directional view the microlens changes in a way such that light originating from the new directional view is more advantageously focused into an image on a detector. The field of view of the microlens is limited only by the area on the substrate over which the droplet can move. An array of such microlenses may be used to facilitate a wider field of view.

The microcapillary heater can include a thin film resistive heater. The fiber itself can optionally include a thin film resistive heater overlying the device, and a plurality of nested microcapillary tubes can optionally provide a plurality of successive concentric heaters overlying the device. The heaters films can be films with uniform, tapered or periodically varying thickness. The heaters can be single layer or multiple layer. Multiple layer films can be superimposed with intervening insulating layers or plural layers can be formed on different angular regions of the microcapillary. Thus one can provide virtually any desired temperature versus length profile along the fiber device.

Abstract: Digital watermark information is inserted into an image by first separating the image into components, e.g., discrete cosine transform (DCT) blocks or image subbands, and then associating one or more bits of the digital watermark information with each of the components. For example, a single bit may be associated with each of the components by modulating the components with selected waveforms representative of the corresponding digital watermark information bits. As another example, the digital watermark information bits may be coded, e.g., using a repetition code, linear block code or convolutional code, to form channel bits, such that the modulating waveforms are selected for the image components based on the corresponding channel bits. The digital watermark information may include a total of B bits of information for representing a particular watermark, such that M=2B distinct watermarks can be generated using the B information bits.

Abstract: A system is provided for securely registering a new user's personal mobility information in a communications terminal having existing registrations. The terminal owner provides information needed to verify the owner's identity and authorizes registration of a specific new user identified by the new user's IMSI. The new user also provides information needed to verify the new user's identity, and requests the registration. A user identity module verifies the identity information provided by the terminal owner and new user, and through intermediaries including a serving system, negotiates with the new user's home system (home location register) to obtain subscription information and appropriate security information for the new user to permit system access. Registration is accomplished by storing this information in the user identity module.
