Step 101: The CRBT user sets one or more CRBTs for the CRBT user's terminal through the multimedia CRBT server, and sets a number for the CRBT.

CRBT users can order through the multimedia ring back tone server or record their own personalized ring tones, such as:

I am in a meeting, it is not convenient to answer your call.

I am driving, it is not convenient to answer your call.

Today's personalized ring tones for different calling users (for girlfriend's ring tones, for parents' ringtones, greetings for friends, greetings to friends and family, etc.) The number of the CRBT can be set by the user, or the multimedia CRBT server sets the number of the CRBT for the CRBT user. The multimedia CRBT server stores the corresponding relationship between the CRBT and the number of the CRBT user to the database of the multimedia CRBT server. In the correspondence table;

The number may be a number, or may be in the form of a terminal, such as a letter, a symbol, and a combination of numbers, letters, symbols, and the like;

Step 102: When the calling user dials the terminal of the CRBT user (that is, the called user) through the terminal of the calling user, the terminal of the CRBT user rings;

Step 103: The CRBT user inputs the CRBT number on the terminal in real time, and the CRBT user terminal sends the number to the multimedia CRBT server.

The CRBT user can input different numbers in real time according to different current scenes or different calling users.

You can set a timeout period, for example, 3 seconds. If the CRBT user does not enter the CRBT number in time, the CRBT user's terminal does not send the number to the multimedia CRBT server, or it can send a default number to the multimedia CRBT server.

Step 104: After receiving the number, the multimedia CRBT server plays the color ring corresponding to the number to the terminal of the calling user.

Pre-conditions: The CRBT user subscribes to the multimedia ring back tone server (for example, through the CRBT portal of the multimedia ring back tone server) or records various personalized ring tones and sets corresponding digital numbers, such as:

1 : I am in a meeting, it is not convenient to answer your call. 2: I am driving, it is not convenient to answer your call.

The multimedia CRBT server stores the correspondence between the digital number of each CRBT user and the CRBT in the corresponding relationship table of the database of the multimedia CRBT server;

Step 201: The calling user dials the called user, and the terminal of the calling user (hereinafter referred to as the calling terminal) sends a SIP (Session Initiation Protocol) invitation request message (INVITE) to the S-CSCF (the call control function of the IMS) Module), if the called user subscribes to the multimedia ring back tone service (ie, the called user is a CRBT user), the S-CSCF sends the invitation request message (INVITE) to the multimedia of the called user's terminal (hereinafter referred to as the called terminal). CRBT server;

Step 202: The multimedia ring back tone server sends an invite request message (INVITE) of the autonomously called terminal to the called terminal.

Step 203: The called user selects the input 2# on the called terminal because the user is currently driving, and is inconvenient to answer the call, where # represents the input terminator;

Step 204: The called terminal returns a SIP 180 response message to the multimedia ring back tone server, where the message body of the 180 response message carries the number of the CRBT input by the called user (ie, the input number 2);

Step 205: After receiving the 180 response message, the multimedia CRBT server starts the CRBT service logic, and finds the CRBT corresponding to the "2" according to the personalized CRBT data set by the called user in the correspondence table: I am driving, it is not convenient to answer you. Telephone

Step 206: The multimedia ring back tone server reserves resources for the CRBT playback.

Step 207: The multimedia ring back tone server adds the ring back tone media resource information as an early-session disposition type to the 180 response message, and then sends the message to the calling terminal; the calling terminal and the multimedia ring back tone server start the multimedia ring back tone. The early media negotiation is performed; Step 208: The calling terminal sends a SIP reliability temporary response confirmation message (PRACK), where the color ring media resource information response is carried;

Step 209: The multimedia CRBT server sends a response response message (200 OK) of the reliability temporary response confirmation message (PRACK) to the calling terminal. Step 210: The multimedia ring back tone server starts playing the color ring tone.

Step 211: The calling terminal receives the multimedia ring back tone.

The above is a signaling procedure of the multimedia ring back tone service implementation in the IMS domain. The application example is to carry the number of the CRBT input by the called user through the 180 response message. In practical applications, there are multiple modes for transmitting the number of the called CRBT user to input the CRBT. For example, the transmission of the number can be realized by issuing a message (PUBLISH).

The implementation of the multimedia CRBT service in the CS domain is similar to the implementation of the multimedia CRBT service in the IMS domain, and is not described in detail here.
