The whole FUC software can be divided into two layers: system software 

and application, as shown in Figure 8.

The concept of virtual operating system is adopted for the system software. 

Based on the commercial operating system pSOS+, the running support 
layer RUNSPT of the limited state machine is oriented to make the 

application irrelevant with the actual real-time operating system, simplify 
the application implementation and improve the application grafting. 

RUNCTRL implements the power-on boot sequence of system’s modules 
and some auxiliary functions of the operating system. It collects and 

redirects the output messages. 

The drivers are also designed with a hierarchical structure, including 
equipment-dependent and equipment-independent drivers. All 

communications within the current equipment adopt the address transfer 
mode to reduce the overhead of the memory block copies. 

The application layer contains the operation and maintenance module 
(OAMM), radio signaling processing module (RSM) and local O&M agent 

module (LMA). The OAMM configures and manages the software, 
parameters, status and alarms of the TPU board. The RSM can be divided 

into the FURRM (Radio Resource Management Module), PAGCHM (Paging 
Access Channel Message Processing Module) and FHM (Frequency Hopping 
Module). These modules implement the signaling flows of circuit switched 

service and packet switched service according to the GSM protocol, and 
they support frequency hopping. LMA is used for system debugging. 

CHP 

The CHP software module is located in the TPU of the TRM in the system.
