Design And Implementation Of IOS Converged Communication Terminal Based On WebRTC

With the rapid development of mobile technology in recent years,users are increasingly demanding in the quality of real-time communication.The emergence of WebRTC technology,with its powerful audio and video engine quickly occupy the market,has a huge impact on multimedia communications industry.But,WebRTC provides JSEP protocols only do simple media function,in communication of enterprise,combing with other signaling protocol is needed to do a complete application.SIP is the establishment of multimedia session,interruption,end playing a big role,and has setted up a development mature and widely used.Therefore,selecting the SIP protocol as WebRTC signaling protocol implementation of real-time communication,is an important trend of multimedia communication industry,and promotes the WebRTC technology widely used.This paper studies deeply the WebRTC and SIP protocol,the MQTT protocol and the LDAP protocol,on the iOS design the communication terminal based on the technology of WebRTC fusion,implements WebRTC application layer gateway in the iOS side application,communication terminal for the fusion performance improvement is of great significance.This paper first expounds the iOS operating system,the characteristics of the WebRTC and related technologies,the SIP protocol,the MQTT protocol and the LDAP protocol.Then the iOS side fusion based on the technology of WebRTC communication terminal to the design of architecture and related modules.The terminal design is mainly divided into two parts: one is based on WebRTC application layer gateway design and WebRTC application in the iOS side design.WebRTC applications provide users with contacts,session,and other services,while WebRTC application layer gateway has realized the SIP server communication with WebRTC application,provide service for WebRTC application.Final papers for the fusion experiments have been carried out to test communication terminal,the results show that the fusion of communication terminal to the initial design goals.
