Analysis And Implementstion Of RCS Services Based On Intelligent Terminal

With the increasing bandwidth of mobile data network,many Internet companies has transitioned from the traditional IP network to the mobile Internet.Free communication services provided by Internet applications cast threats on the telecommunications operators which rely heavily on voice and SMS.Based on previous situation,GSMA proposed RCS in order to cope with the challenges of Internet companies that increasingly threaten the interests of telecommunications operators and avoid being the flow of traffic.First,the thesis introduces the core technologies of IMS,and analyzes the architecture of IMS and introduces a kind of interoperation between LTE and GSM / TD / WCDMA scheme;Second,it analyzes the function of the new contacts and new message of RCS: create or dissolution group,join or exit group,the backup and recovery of contact,two-dimensional code card and personal center and other functions;Then it introduces the hierarchical architectureand development components of android system,designs the RCS development and functional architecture: the application layer,the application framework layer,the system runtime layer,the hardware abstraction layer and the Linux kernel layer;the development components are the activity,service,broadcast receiver and content providers;RCS architecture includes RCS application layer,RCS interface layer,RCS service layer and RCS data layer;Finally,it configures the development environment to install the software and implement RCS related functions.The thesis conducts specific tests on functions of RCS software and comparations.The basic theory of software testing,the classification of testing and testing of several major methods are introduced to determine the thesis test scheme.The main functions are tested and analyzed on the results of new message,new contacts and personal centers,finds that RCS specific functions as expected to achieve and work properly;compared with the traditional message and contacts functions,highlighting the richness of RCS functions;compared with WeChat,highlighting the same function under the same conditions that RCS performance better.In this thesis,the background of RCS is analyzed and the significance of the research is determined.The core theory knowledge and the specific functions of RCS are analyzed.The architecture,development components and development tools of RCS are studied,and the development framework and network of RCS are designed.Architecture and the specific realization of the relevant business functions;Finally,a variety of software testing and analysis,highlighting the advantages of RCS.Through the research of the above contents,it has certain reference significance and practical value for the deployment and promotion of RCS by telecommunications operators.
