Design And Implementation Cell Phone Ring Tones Download System

Mobile phone ring tones download system, which is on the basis of the "cell phone ring tone download " business and "cell phone ring tones" business and combined with the characteristics of the two businesses, re-designed its organization of a new music class value-added services, also known as combined CRBT(color ring back tone) and ringing, referred to as color vibration.This service provides the function to download ring tones when the system is playing ringback tone to the callers. That is, if the calling user wants to download ring tones to the terminal and set the tone for your cell phone ringing, they just need to do some simple button operations on cell phone. CRBT system and color vibration system together to complete the follow-up work to send the user ring tones, which provides users with a new "download while listen" model, and improves the users'participation and enthusiasm to CRBT.Color vibration center consists of Main unit and Servlet unit. Main unit is the main control module, which is in charge of checking the CRBT database whether there is new service request; Servlet module is mainly responsible for providing ringtone file download services for WAP terminals. Its main features are:receiving user's download request; analyzing the information of Head section, and get phone audio formats supported by the terminal; sent the specified number of the appropriate type of ring tones file to the user mobile phone; if the download was successful, color vibration will record a fee, or insert a failure record into the database; recording audio information of each download terminals and enriching mobile phone configuration information table; presenting WML error message page that cannot find a ring that matches the type of terminal to the users.This paper firstly introduces the main technology used in color vibration and wap push technology, then introduces the two parts of the design of color vibration in detail. And then introduces the database structure. Finally lists the test cases used in Project acceptance stage.
