Method for communication buffer management communicates messages between local and remote hosts. Socket, process buffer and reserve buffers allocated. Process and reserve buffers differentiated for transmit and receive. Global memory pool partitioned into process and reserve buffer pools; reserve buffer pool partitioned into transmit and receive pools. Messages stored in process buffer, but reserve buffer stores messages if low memory (POS). Communication system and mobile device include communication manager storing messages in process buffers; if POS exists, in reserve buffers. Communication buffer manager used for memory management, allocation, reclamation. Both adapt for static and dynamic memory management.
