status and alarm management, software version management,
device test and external alarm collection.
ii. DBS
The whole application layer is designed with the database as a core.
The database coordinates to assign configuration parameters. It
also synchronizes data between the active and standby CMMs and
between the foreground and the background.
iii. LMU
It is the local O&M unit, including two parts: foreground agent and
background operation interface.
It works with the database synchronization module to complete the
local parameter configuration, equipment status and alarm
collection. It also includes operating interface of equipment test to
implement test functions of the local BTS.
The system tool part is a series of developer-oriented tools for
system diagnosis and test to rapidly locate faults.
FUC
The FUC software module is located in the TPU of the TRM module. It
processes the radio signaling over every radio carrier and signaling on the
BSC interface and manages all channels. Its major functions are as follows:
1. It processes and converts GSM signaling protocols, including the layer-
2 protocol LAPD with BSC, the layer-2 protocol HDLC with CMM, the
layer-2 protocol LAPDm with the Um interface and the layer-3 radio
resources management protocol of GSM.
2. It is responsible for the TDMA multi-frame framing on the Um interface,
frame number (FN) receiving, frequency hopping calculation and
management & control over CHP.
3. It manages OB06 and loads the FUC software and DSP program. It
supports packet switching services (GPRS or PS for short).
