摘要： A call servicing system permits service agents to service customer calls over a data network. The call servicing system includes customer switches that direct calls to and from the customers, agent terminals for use by the service agents in servicing the customer calls, a network switch, a call translation unit, and an Automatic Call Distribution (ACD) server. The network switch receives the customer calls and transfers the calls to the call translation unit under direction of the ACD server. The call translation unit routes the calls to selected service agents. The ACD server selects the service agents to service the calls, and controls the call translation unit to forward the calls to the agent terminals associated with the selected service agents over the data network.

摘要： A method and apparatus for locating a desired record amongst a plurality of records in a telephone directory involves associating a frequency field with each of the records, the frequency field being operable to store a frequency metric. A characteristic field is also associated with each of the records, the characteristic field being operable to store a characteristic representation of at least one identifying characteristic of a rendering associated with the record. An input representation of a rendering purporting to identify the desired record is produced and the input representation is compared with the contents of the characteristic fields of at least some of the records and confidence metrics are assigned to the records respectively, each of the confidence metrics representing a respective probability that a respective record is the desired record. A determination is then made as to which of the records have the first and second highest confidence metrics. The frequency fields of the records having the first and second highest confidence metrics are then read and the record with the highest frequency metric is identified as the desired record. Instruction codes stored on a computer-readable memory medium may be used to configure a general purpose computer to effect the method.

摘要： A call servicing system facilitates the servicing of customer calls by service agents. The call servicing system includes local customer switches, local agents switches, a network switch, and an Automatic Call Distribution (ACD) server. The local customer switches direct calls to and from the customers and the local agent switches direct calls to and from the service agents. Remote service agents connect to the local agent switches using a single standard telephone line. The network receives a call from one of the customers, detects information from the customer call, and routes the customer call to a remote service agent over the single standard telephone line. The ACD server receives the detected information from the network switch, determines that the remote service agent can service the customer call, and controls the network switch to route the customer call to the remote service agent over the single standard telephone line.

摘要： Complex signal samples (s(k)) of an input signal are supplied via a frequency down-shifter (23) to a digital filter (24), and to a time-frequency transform unit (28) which produces a plurality of frequency components (S1(k) to S6(k)) each associated with a respective frequency band (1=1 to 6) within a bandwidth of the input signal. The frequency component having the maximum momentary energy is determined (29, 30) to determine the down-shifting frequency for the associated frequency band to be filtered, and to determine a complementary up-shifting (25) following the digital filter to produce an output signal (f(k)). The filter can be a bandpass filter or a bandstop filter, especially for reducing co-channel interference in different types of wireless communications systems.

摘要： A novel transport architecture and network elements use nodes in a ring or virtual ring configuration. Information is exchanged among the nodes in a continuous series of containers carried in a superframe. A container is assigned to a destination node and is divided into partitions which are allocated for source nodes. Therefore, when a container destined to a particular destination node arrives at a node and if this node has information to send to the destination node, it fills the allocated partition within the container with information destined to the destination node. The sizes of the superframe, containers and partitions are all variable dynamically or statically.

摘要： The process of the present invention is based on a hexagonal cellular platform where six, or a multiple of six, frequency groups are directionalized and reused in the same direction. Directional antennas are located in the center of each cell. Each antenna radiates into a 60 DEG sector of the cell. The reused frequency groups are aligned along the 0 DEG , 120 DEG , and 240 DEG axes of each cell. Each axis has three layers, the two outer layers having an identical frequency reuse series. The frequency groups are reused in the same direction along each axis, reducing the number of dominant interfering cells to one.

摘要： System and method for optimally updating a neighbor set for use by a mobile unit during soft handoff of the mobile unit in a CDMA cellular telephone environment is disclosed. A two-step process is used to ensure that the individual neighbor sets of active set members are combined in a manner such that only pilots representing the more important sectors are included in the updated neighbor set and pilots representing the less important sectors are excluded therefrom. In the first step, active set members whose RTD is more than twice as great as an OWD threshold are eliminated from consideration. In the second step, the neighbor set of the mobile unit is updated using the sectors included in the individual neighbor sets of the active set members that were not excluded by the first step, wherein those sectors are included in the updated neighbor set according to the number of individual sets in which they are found and their priority within those sets. In an alternative embodiment, a combined carrier-to-interference ratio for each of the individual neighbor set members is also used in updating the neighbor set. In an alternative embodiment, the individual neighbor set of the active set member having the shortest RTD is used as the updated neighbor set.

摘要： A diversity selection process for a wireless terminal having two antennas is disclosed which tests reception on both the main antenna and a diversity antenna during the period when the terminal is transmitting and tests reception of a different channel (for example, for mobile assisted hand-off) during an idle period when the terminal is neither receiving or transmitting data. The antenna with the greater signal strength is selected for the next frame. Thus, both diversity and mobile assisted hand-off measurements can be made with a single receiver.

摘要： A base station for a wireless communications system comprises two antennas (14, 26) spaced by a small distance (d) for receiving a signal from a mobile terminal, and two receivers (34, 36) coupled to the antennas for providing first and second received signals with a phase difference dependent upon a direction of the mobile terminal relative to the antennas. A nulling linear signal combiner (38-44) combines the received signals to determine the phase difference, and hence direction of the mobile terminal, using an adaptively adjusted complex weight Wk which is supplied via an arctangent function (50) to a d.c. tracking filter (50). The determined direction, and distance determined from signal strength information available in the base station, identify the location of the mobile terminal. The location is itself useful information, and can be monitored over time to determine velocity of the mobile terminal and/or can be used to identify candidate terminals for handoff from a macrocell to a microcell of the system.

摘要： While setting up a fixed wireless system, each subscriber radiotelephone is configured to a permanent home cell. Subscribers located at the border of a cell may be configured to multiple cells for better coverage. The signal levels at the border subscriber's position are received and the mean values of each determined. These mean values are listed in descending order. If the largest mean value is greater than a predetermined threshold, the subscriber is configured to only the home cell. If the largest mean value is within a predetermined range, the second largest mean value is evaluated to determine if it is within the predetermined range. If so, the subscriber is configured to both serving cells. If the second largest mean value is outside the predetermined range, the subscriber is configured to only the home cell.
