3. Functions
3.1 Main lunctions ol BTS
The main function of BTS subsystem is as follows:
1) Call control
Interworking with MS and 880, it sets up and releases Mobile-to-Land, Land-to-Mobile, Mobile-to»MobiIe
calls that entered into BTS and supports Softer, Soft, Hard handofi lunction. In addition. it executes
Markov call processing lunction tor setting up test call,
2) Call resource management
It selects channel element resources necessary tor call setup by sharing the load. and collects them upon
call release, Besides. depending on handotl occurrence lrequency ol each BTS, it reserves resources
exclusive lor handofi and supports stable handoll.
a) Downloading
BTS downloads OS and Application Code that it needs by processor lrom upper processor. Upon
downloading of OS and Application Code. ii the version is identical. it does not receive loading again and,
instead, it is run with them transferred lrom llash memory which is nonvolatile memory.
This is to get rid of unnecessary loading time and drastically reduce the initialization time 01 BTS. SCPA,
after downloading Application Code, builds and operates database regarding own status, configuration and
operation lrom PLD Data directly translerred lrom BSM and transfers configuration inlormation necessary
for initialization to FlCPAt
4) Configuration. status lunction
For the operation and maintenance ol BTS. it executes status management of processor, status
management oi device. management of configuration information and operation inlormation. etc. SCPA,
interworking with RCPA and 850. BSM, perlorms operation and maintenance ol entire BTS.
5) Trouble, alarm ma management
it manages hardware troubles. i.e.. power trouble, processor function trouble, and cable open trouble or
soltware troubles that do not require hardware device for detection, RCPA in BTS detects trouble or
alarm of device managed by it, repons it to SCPA, and SCPA reports it to upper processor along with
necessary measures. Trouble by hardware is detected through BAMA block in SCPA for management.
5) Test
As tor channel element (in particular, Trallic Channel), by periodically testing available resources on—Iine, it
increases reliability oi resources.
Depending on the result at the test, it iudges whether to continuously use it as call resources, A test at
the request ol operator is also enabled. CE related tests include one that tests CE's WW and one that
uses BTS Markov Call,
7) Overload control
According to the load ol the processor, it IS divided into Normal, Minor, Major. Critical, and depending on
corresponding grade. it takes necessary measures such as originating call barring, terminating cal barring.
8) Statistics and measurement
It gathers and reports various statistics (cal statistics, process statistics, paging statistics, CE(Channel
Element) statistics, BTS performance statistics, CAl(common Air lntedace) statistics, etc) Statistics is
basically gathered hourly. reported to BSM. and as occasion demands, it can be measured by inputting the
time and cycle that operator wants.
9) Remote Control
lt isolates or resets rectifier power, processor or device When on BSM, operator gave isolation (or Reset)
command, SCPA, by receiving it, picks out the subject (BAMA or RCPA) that actually pertorms isolation (or
Reset), and transfers message to corresponding isolation (or Reset) subject tor isolation (or Reset),
LG/C Proprielary 1 1
10) Inventory lunction _ _ _ _
Its purpose is to manage the history oi each board. lt manages the history of specific board and specific
BTS (CN application, repair history, or special notes).
