Open Mobile Platform is an Open Platform providing ability of telecommunication.It provides developers with rich business abilities

including:SMS

MMS

maps

positioning

etc.The access system of Open Mobile Platform requires asynchronous processing HTTP requests for the client

and various systems of the platform also need to use a large number of asynchronous HTTP requests to send message.Netty is an asynchronous event-driven network applications open source framework

which is used for rapid development of maintainable high performance

high scalability protocol servers and clients.This paper briefly describes the design idea and concrete implementation of using open source framework Netty for providing a convenient and easy http client which can send an asynchronous HTTP request.
