Design And Implementation Of Multimedia Mobile Agent's APP

In recent years,with the popularization of 4G networks,the development of Internet technologies,and the improvement of the performance of mobile phones,mobile phones have gradually become the main tool for people to access the Internet.At the same time,people are increasingly demanding high-quality services with the development of the economy and the progress of society.For the call center domain,the traditional way of serving users only through voice is no longer able to meet the needs of users.The maturity of the mobile Internet and related technologies has made it possible to migrate mobile Internet technologies to the call center field and provide users with more diversified and more efficient services.Through the use of mobile Internet technology,on the one hand,it is possible to liberate agents so that they can no longer be confined to the computer.Instead,they can access the system anytime and anywhere to provide services for users.On the other hand,agents can communicate with users through multimedia and provide users with more diversified and more efficient services.This not only satisfies the needs of the enterprise's providing users with personalized and diversified services,but also satisfies the user's desire for higher quality services.Therefore,this paper designs and implements a multimedia mobile agent Android APP in the call center system.Based on Web Socket protocol and Web RTC open source library,this paper designs and implements the multimedia communication module of the system,including instant messaging module and audio and video call module.The instant message module mainly includes instant text chat,emoticon chat,form chat,image chat,voice clip chat,and small video chat.Among them,the last three is realized with the help with a file server.Audio and video call module mainly includes audio real-time calling function and video real-time calling function.Through the above-mentioned diversified ways of communication,agents can provide users with fast,efficient,and personalized services,thereby enhancing user experience and users' satisfaction.On the basis of realizing the multimedia communication module,in order to ensure the system's ease of use,high efficiency,stability and robustness,the system has also designed and implemented a network communication framework,a picture management framework,and a data management framework.Among them,the network communication framework is implemented based on Retrofit2,Ok Http3,and Rx Java2.It adopts the hierarchical design strategy,and is divided into the network request encapsulation layer,the network request processing layer,and the network request thread scheduling layer.So it solves the problem of efficiently transmitting and receiving small files.The picture management framework is based on Lru Cache and Disk Lru Cache.It adopts the three-level caching strategy and the large picture blurred strategy to solve the problem of high efficiently displaying images and memory leak in the Android system.The data management framework is implemented based on Shared Preference and SQLite.It adopts the strategy of classification processing to solve the problem of quick access to small data and concurrent operation of big data.In addition,this paper also designed and implemented other specific functional modules related to business logic.It mainly includes the register and login module,the agent status management module,service history module,and agent data acquisition module.Finally,this paper carries out function test and performance test to this system.By black box manual test and automatic test to this system,the availability of this system is verified.Through the performance test of the system's stability,start-up time,CPU usage,memory usage,and network bandwidth,the system's efficiency,reliability,and robustness are verified.
