Design of TCP/IP Based Asynchronous Communication Peer in Handset

The socket API, as the popular programming interface of TCP/IP stack,cant offer convenient support for integrating commercial Internet accessing software products from 3rd part vendors into handsets. It advises to design an asynchronous communication peer to conveniently provide transport interfaces for upper application in event-driven mode. It details an idea for designing asynchronous communication peer, and meantime providing description about a feasible implementation.
