Call Disconnect. The process that releases the resources handling a particular call. The disconnect
process beings either when the mobile station user indicates the end of the call by generating an
on-hook condition or other call release mechanism, or when the base station initiates a release.
Call History Parameter(COUNT) . A modulo-64 event counter maintained by the mobile station and
Authentication Center that us used for clone detection.
Candidate Set. The set of pilots that have been received with sufficient strength by the mobile station
to be successfully demodulated, but have not been placed in the Active Set by the base station. See
also Active Set. Neighbor Set, and Remaining Set.
. See Code Division Multiple Access
CDMA Channel . The set of channels transmitted between the base station within a given CDMA
frequency assignment. See also Forward CDMA Channel and Reverse CDMA Channel.
CDMA Channel Number. An 11-bit number corresponding to the center of the CDMA frequency
assignment.
CDMA Frequency Assignment. A 1.23MHz segment of spectrum centered on one of the 30KHz
channels of the existing analog system.
Code Channel . A subchannel of a Forward CDMA Channels. A Forward CDMA Channel contains 64
code channels. Code channel zero is assigned to the Pilot Channel. Code channels 1 through 7 may
be assigned to the either Paging Channels or the Traffic Channels. Code Channel 32 may be
assigned to either a Sync Channel or a Traffic Channel. The remaining code channels may be
assigned to Traffic Channels.
Code Division Multiple Access (CDMA). A technique for spread-spectrum multiple-access digital
communications that creates channels through the use of unique code sequences.
Code Symbol . The output of an error-correcting encoder. Information bits are input to the encoder
and code symbols are output from the encoder. See Convolutional Code.
Continuous Transmission . A mode of operation in which Discontinuous Transmission is not
permitted.
Control Mobile Attenuation Code(CMAC). A 3-bit field in the Control-Filler Message that specifies
the maximum authorized power level for a mobile transmitting on an analog reverse control channels.
Convolution Code . A type of error-correcting code. A code symbol can be considered as the
convolution of the input data sequence with the impulse response of a generator function.
CRC. See Cyclic Redundancy Code.
Cyclic Redundancy Code (CRC). A class of linear error detecting codes which generate parity
check bits by finding the remainder of a polynomial division.
Data Burst Randomizer. The function that determines which power control groups within a frame
are transmitted on the Reverse Traffic Channel when the data rate is lower than 9600 bps. The data
burst randomizer determines, for each mobile station, the pseudo random position of the transmitted
power control groups in the frame while guaranteeing that every modulation symbol is transmitted
exactly once.
