RMI: Remote MMI, i.e., PC side, which uses AT commands to communicate with Protocol stack.

L4: The adaptation layer between MMI/AT and protocol stack.

L4A: Layer 4 Adaptation to translate primitives sent from upper layers to function calls.

L4C: Layer 4 Controller, coordinates all L4 modules to serve upper layers.ATCI: AT Command Interpreter.

UEM: User Equipments module used to abstract basic device drivers like keypad, LED, GPIO.

PHB: Phone Book management.

SMU: Security Management (SIM, STK).

CSM: Call Service Management (bearer capability handling, CSD/FAX service, CC, SS).

RAC: Registration Access Control (GSM/GPRS registration management,PLMN list/selection, RSSI report)

SMSAL: SMS Application Layer (message storage, MO/MT messages, CB). TCM: Terminal Context Management (PDP context profiles, context

activate/deactivate, relay of packet data), interface to PPP/TCPIP/SNDCP.ENG: Engineer Mode to log information.

Task Management & Identification

Defined in “Stack_config.h”

Used to define index of all modules and all tasksDefined in “syscomp_config.c”

Used to map MODULE-ID to TASK-ID

Defined in “syscomp_config.c”

Used to define information of all tasks, e.g., task’s name, task queue’s name, priority, size of external/internal queue, task creation function, whether to use internal http://ed for customer defined modules or tasks.

Global array containing component task information, which will be filled in while calling stack_init_comp_info().
