Soft Handoff . A handoff occurring while the mobile station is in the Mobile Station Control on the Traffic Channel
State. This handoff is characterized by commencing communications with a new base station on the same CDMA
frequency assignment before terminating communications with the old base station. See also Hard Handoff.
SOM . Start-of-Message Bit.
SPS. Symbols per second.
- An identification of certain characteristics of a mobile station. Classes are defined in Table 2.3.3-1.
Status Information. The following status information is used to describe mobile station operation when using the
analog system.
Serving-System Status. Indicates whether a mobile station is turned to channels associated with System A or
System B.
First Registration ID Status. A status variable used by the mobile station in association with its processing of
received Registration ID messages.
First Location Area ID Status. A status variable used by the mobile station in association with its processing of
received Location Area ID messages.
Location Registration ID Status. A status variable used by the mobile station in association with its processing of
power-up registration and location-based registration.
First Idle ID Status. A status variable used by the mobile station in association with its processing of the Idle Task.
Local Control Status. Indicates whether a mobile station must respond to local control messages.
Roam Status. Indicates whether a mobile station is in its home system.
Termination Status. Indicates whether a mobile station must terminate the call when it is on an analog voice
channel.
Supervisory Audio Tone (SAT). One of three tones in the 6 kHz region that is transmitted on the forward analog
voice channel by a base station and transponder on the reverse analog voice channel by as mobile station.
Supplementary Digital Color Code (SDCC1, SDCC2). Additional bits assigned to increase the number of color
codes from four to sixty four, transmitted on the forward analog control channel.
Symbol. See Code Symbol and Modulation Symbol.
Sync Channel. Code channel 32 in the Forward CDMA Channel which transports the synchronization message to the
mobile station.
Sync Channel Superframe . An 80ms interval consisting of three Sync Channel frames (each 26.666…ms in length).
System. A system is a Cellular telephone service that covers a geographic area such as a city. Metropolitan region,
country, or group of countries. See also Network.
System Time. The time reference used by the system. System Time is synchronous to UTC time (except for leap
seconds) and used the same time origin as GPS time. Offset by the propagation delay from the base station to the
mobile station. See also Universal coordinated Time.
Timer-Based Registration. A registration method in which the mobile station registers whenever a counter reaches
a predetermined value. The counter is incremented an average of once per 80 ms period.
Time Reference. A reference established by the mobile station that is synchronous with the earliest arriving
multipath component used for demodulation.
