Analog Access Channel
. An analog control channel used by a mobile station to access a system to obtain service.
Analog Color-Code.
An analog signal (see Supervisory Audio Tone) transmitted by a base station on an analog
voice channel and used to detect capture of a mobile station by an interfering base station or the capture of a base
station by an interfering mobile station.
Analog Control Channel.
An analog channel used for the transmission of digital control information from a base
station to a mobile station or from a mobile station to a base station.
Analog Paging Channel.
A forward analog control channel that is used to page mobile stations and send orders.
Analog Voice Channel.
An analog channel on which a voice conversation occurs and on which brief digital
messages may be sent from a base station to a mobile station or from a mobile station to a base station.
Authentication.
A procedure used by a base station to validate a mobile station’s identity.
Authentication Center (AC).
An entity that manages the authentication information related to the mobile station.
Authentication Response (AUTHR).
An 18-bit output of the authentication algorithm. It is used, for example, to
validate mobile station registrations, origination and terminations. A method of registration in which the mobile
station registers without an explicit command from the base station.
AWGN.
Additive White Gaussian Noise.
Bad Frames
. Frames classified as erasures (frame category 10) or9600bps frames, primary traffic only with bit
errors (frame category 9). See also Good Frames.
Base Station.
A station in the Domestic Public Cellular Radio Telecommunications Service, other than a mobile
station, used for communicating with mobile stations. Depending upon the context, the term base station may refer to
a cell, a sector within a cell, an MSC, or other part of the Cellular system. See also MSC.
Base Station Authentication Response (AUTHBS).
An 18-bit pattern generated by the authentication algorithm.
AUTHBS is used to confirm the validity of base station orders to update the Shared Secret Data.
Base Station Random Variable (RANDBS).
A 32-bit random number generated by the mobile station for
authenticating base station orders to update the Shared Secret Data.
BCH Code.
See Bose-Chaudhuri-Hocquenghem Code.
Busy-Idle Bits.
The portion of the data stream transmitted by a base station on a forward analog control channel that
is used to indicate the current busy-idle status of the corresponding reverse analog control channel.
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.
