－》L2/L3/L4 Protocol Stack
    这部分包含大量的GSM/GPRS需求以及提供一个优秀的GSM/GPRS平台给应用程序。本地MMI和远程PC通过AT命令可以方便的使用该软件平台。详细的结构如下：
  RMI: 远程MMI，比如PC端，可以使用AT命令通过串口与协议栈进行通讯。
  FMI: Feature rich MMI, described in the above section. This is the production co-worked with Pixtel.
  L4: Layer 4. L4 is a task through which FMI and/or RMI communicate with PS. L4 task includes several sub-modules.
  ATCI: AT command interpreter. Interprets the AT commands from PC side and commands the L4C to do the relative actions.
  L4A: L4 adaptation layer for FMI. The SAP between FMI and L4A is primitive base.
  L4C: L4 control entity. Handles all applications request and response.
  UEM: User equipments adaptation. Adaptation for drivers, like Keypad, LED, GPIO, Audio…etc.
  PHB: Phone book management. Handles the phone books related processing, like: sorting…etc.
  SMU: SIM management unit. Handle the security management, and STK.
  CSM: Circuit switching protocol stack management.
  RAC: Registration access control.
  SMSAL: Short message service application layer.
  TCM: Terminal context management.
  NVRAM: Non-volatile RAM. This is adaptation layer to flash memory.
  SIM: Subscriber identity module. Handle SIM behavior as ETSI 11.11 description.
  DATA: Circuit switched data service. Data task includes several sub-modules.
  FAX: Group 3 Facsimile.
  TDT: Transparent circuit switching data.
  L2R: Layer 2 relay protocol for non-transparent circuit switching data.
  RLP: Radio link protocol for non-transparent circuit switching data.
  CC: Circuit-switched call control.
  SS: Supplementary service.
  SMS: Short message service.
  SM: Session management.
  MM/GMM: Mobility management/GPRS mobility management.
  SNDCP: Subnetwork dependent convergence protocol.
  LLC: Logical link control.
  RR: Radio resource management. RR task includes several sub-modules.
  RRM: Handles cell selection and PLMN selection.
  RMPC: Handles the procedures in Idle/Dedicated state including the surrounding cell scheme and measurement reporting.
  LAPDM: Handles the procedure defined in GSM layer 2.
  RLC: Radio link control protocol.
  MAC: Medium access control protocol.
  MPAL: Adaptation layer for RR and L1A.

  PPP: Point to Point protocol layer. This is client PPP layer.
