Abstract: Audio degradation is minimized in scenarios where tandem coding occurs. One such scenario is in the environment of voice mail service. Characteristics of an audio information signal are determined, and the signal is classified as to whether further coding should be performed and, if so, which rate/type of coding should be performed. Characteristics of the audio signal which are determined are, inter alia, quality characteristics, rate of previous coding, type of previous coding and the source of previous coding of the audio information signal. The source of previous coding determined may further include, inter alia, an analog network, a digital network, a PSTN or a wireless communication system. Based on this information, the voice mail service will either choose not to further code the audio information signal or code the audio information signal with the best coding algorithm available.

Abstract: In a method for allocating a system resource to subscribers of a wireless communication system a resource sensitivity indicator is determined for a system resource allocated by the wireless communication system for each of a first subscriber and a second subscriber. The system resource may include a level of service, a channel frequency, or a data rate. Next, an inefficient allocation of the system resource detected. One of the first and second subscribers having a lower resource sensitivity indicator is selected. Finally, an allocation of the system resource is changed for the selected subscriber unit to increase the efficiency of the allocation of the system resource.

Abstract: In a telecommunications system, data having a higher sensitivity and data having a lower sensitivity are identified within a data set. The data having a higher sensitivity is encrypted to produce encrypted sensitive data. Thereafter, the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The encrypted data set is then transferred from a sending unit to a receiving unit. Decryption information may be appended to the encrypted sensitive data before the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The decryption information may include an algorithm identifier, a key identifier, and receiver response instructions. At the receiving unit, the data set is decrypted to recover the data having lower sensitivity. A second decryption of the encrypted sensitive information recovers the data having a higher sensitivity.

Abstract: A communication system implements detection of bad frames of information by utilizing multiple bit correction thresholds. Equipment used within the communication system adapts to different signaling environments by dynamically altering the bit correction threshold based on a history of the number of consecutive bad frames of information that have been previously erased and the number of bits corrected by a channel decoder (202). By implementing this dynamic bit correction threshold, sufficient bad frame indication (BFI) detection and receiver sensitivity can be obtained simultaneously, which results in an improved perceived audio quality to the end user.

Abstract: In a transceiver for transmitting a communication signal from an antenna array in a wireless communications system, a different element pilot is transmitted from a plurality of antenna elements in an antenna array. Thereafter, transmitter control data based upon measured characteristics of the element pilots as measured at a subscriber unit is received at the transceiver. In response to the transmitter control data, a plurality of adaptive array weights for modifying a plurality of element communication signals are determined. Next, the transceiver determines that the subscriber unit is ready to receive a communication signal transmitted from the antenna array and weighted according to the plurality of adaptive array weights. In response to determining that the subscriber unit is ready, the transceiver modifies the plurality of element communication signals according to the determined plurality of adaptive array weights.

Abstract: In a transceiver in a wireless communications system, data is transmitted from the transceiver to subscriber units, wherein each subscriber unit has a requested transmit power and an allocated transmit power, and wherein the allocated transmit power is based upon the requested transmit power. A request for an additional power allocation is detected, wherein such additional allocation causes a total requested power to exceed a maximum transceiver power. In response, allocated transmit power is limited for a minimum number of selected subscriber units needed to reduce a total transceiver transmit power below the maximum transceiver power.

The MSC-NI provides for conversion of the format of the data between the internal ATM format and a synchronous format. In one embodiment, the synchronous format is used for communication between the MSC and the NI, responsive to the MSC and the BSC, and the BTSI provides for communicating mobile subsystem information between the BTS and the XC, responsive to the BTS and the BSC.

Abstract: For a wireless communications system service area (20), a population database (24) is selected that describes a population in database regions (22) within the wireless communication service area (20). A transportation database (46) that describes transportation arteries in the wireless communications system service area (20) is also selected. The process then calculates an initial offered load (70) for each database region (210), wherein the initial offered load is based upon market factors. Thereafter, a portion of each initial offered load (70) is allocated (212) to a transportation distribution pool (76). Other portions of each initial offered load (70) may be allocated (212) to regional distribution pools (74). The offered load in the transportation distribution pool (76) is then distributed (220) over the transportation arteries (36, 38, 40).

Abstract: A base station system (BSS) encompasses a base station controller (BSC), ATM transcoder (AXC), and one or more Base Tranceiver Subsystems (BTS). The AXC provides for the coupling of external mobile subscriber subsystems (MS) and a public switched telephone network (PSTN). The BSC provides for communication with and control of the ATM transcoder hub subsystem. In one embodiment, the ATM transcoder subsystem provides a first set of signals to the BSC subsystem to signal the base station controller as to call flow management data. The BSC is responsive to the first set of signals from the ATM transcoder hub to generate a second set of signals coupled back to the ATM transcoder hub. This second set of signals provides for the control of transcoding and conversion necessary to communicate between a wireless air communications format data and a call management protocol format data utilized in communication to the public switch telephone network.

Abstract: In a wireless communications system, a subscriber unit transmit power is determined. Thereafter, a power margin is determined by subtracting the subscriber unit transmit power from a maximum transmit power. In response to a current communication mode of the subscriber unit, a predetermined power margin requirement for the current communication mode, and the current power margin, a communication mode quality is estimated. Either the power margin or communication mode quality may be indicated at the subscriber unit, or reported to the infrastructure of the wireless communications system. In response to an unsatisfactory power margin or communication mode quality, the infrastructure may make adjustments to improve service.

Abstract: In a wireless communications system (20), a beacon having a first radiation pattern (28) covering a portion of a subscriber service area (34) covered by a base station is transmitted. A subscriber (36) reception quality is then measured to produce a first beacon quality measurement (210). Thereafter, the first radiation pattern is changed to a second radiation pattern (32, 212), and a subscriber reception quality of the beacon transmitted with a second radiation pattern is measured to produce a second beacon quality measurement (214). In response to the first and second beacon quality measurements, a traffic channel radiation pattern (32) is selected (218), wherein such radiation pattern covers a portion of the subscriber service area. In a preferred embodiment, the beacon carrier frequency is the same as the traffic channel carrier frequency.

Abstract: In a wireless communication system using a power control command to control power of a transmitted traffic channel (58), a signal from a transmitter (64) is received (104) via a channel. A channel quality is measured (70, 108) using the signal from the transmitter. In response to the measured channel quality (70) exceeding (80, 110) a channel quality threshold (82), a decrease traffic channel power command is sent (112) to the transmitter, and a channel quality threshold is increased (114). In response to the channel quality threshold (82) exceeding (80, 110) the measured channel quality (70), an increase traffic channel power command is sent (116) to the transmitter, and the channel quality threshold is decreased (118). A traffic signal quality may be measured (72) and compared (88) to a traffic signal quality threshold (86). The result of the comparison (132) may be used to adjust (134) the channel quality threshold (82).

Abstract: In a code division multiple access (CDMA) signal demodulator in a communication system (50), samples of a CDMA signal are stored in a sample buffer (52). A plurality of the samples that represent a plurality of chips of a symbol are then recalled from the sample buffer (52). Thereafter, the plurality of samples are demodulated in parallel (56) using a selected user code (68) to produce at least a portion of a user's symbol in the code division multiple access signal. Signals from multiple users (22, 24) having multiple fingers are demodulated by sharing the resources of a parallel demodulator (56). Signal searching may use the same parallel demodulator (56). Fingers for multiple users may be dynamically allocated and reallocated according to the needs of each user's signal and the total demodulation resources available.
