Embodiment 1

[0018] figure 1 It is a flow chart of a SIP-based color ring playing method provided by an embodiment of the present invention, such as figure 1 As shown, the methods described include:

[0019] S101. Receive a CRBT play request message, and generate a CRBT play notification message according to the received CRBT play request message;

[0020] In the embodiment of the present invention, when the mobile switching center (MSC, Mobile Switching Center) receives the call request of the calling party, the MSC judges whether the called party has opened the color ring service, and if the called party has opened the color ring service, then the MSC Set up the connection with the CRBT server through SIP signaling. In the embodiment of the present invention, the MSC sends a SIP-based CRBT play request message to the CRBT server to establish a connection with the CRBT server. The CRBT play request message can be an invitation based on SIP The (INVITE) message may be an INVITE message c...

Embodiment 2

[0053] Figure 5 It is a block diagram of a SIP-based CRBT playing device provided by an embodiment of the present invention, such as Figure 5 As shown, the SIP-based CRBT playback device 500 includes:

[0054] Play request receiving unit 501, for receiving the SIP-based CRBT play request message;

[0055] In the embodiment of the present invention, when the mobile switching center receives the call request of the calling party, the MSC judges whether the called party has opened the CRBT service. 500, the MSC establishes a connection with the CRBT player 500 by sending a SIP-based CRBT play request message to the play request receiving unit 501, and the CRBT play request message may be a SIP-based INVITE message. The play request receiving unit 501 receives the CRBT play request message sent by the MSC. The CRBT play request message may also include calling party information, called party information, and CRBT track information. In the embodiment of the present invention, t...

Embodiment 3

[0068] An embodiment of the present invention provides a color ring playing system, such as Figure 6 , including the calling MSC 601 and the ring back tone server 602.

[0069] Wherein, the CRBT server 602 is configured to receive the SIP-based CRBT play request message sent by the calling MSC601, generate a CRBT play notification message according to the received CRBT play request message; send the CRBT play notification message to the calling MSC 601; receive The calling MSC 601 sends the CRBT play confirmation message, and plays the CRBT according to the received CRBT play confirmation message.

[0070] The CRBT server in this embodiment can be the CRBT playing device in Embodiment 2, and the CRBT playing notification message sent to the calling MSC is an INFO message, and the CRBT playing confirmation message sent by the calling MSC is a 200 for INFO message; If the CRBT play notification message sent by the calling MSC is a NOTIFY message, then the CRBT play confirmatio...

Abstract

The invention provides an SIP-based polyphonic ringtone playing method comprising the following steps of: receiving a polyphonic ringtone playing request message based on the SIP, and generating a polyphonic ringtone playing notification message according to the received polyphonic ringtone playing request message; sending the polyphonic ringtone playing notification message; receiving a polyphonic ringtone playing confirmation message, and playing a polyphonic ringtone according to the received polyphonic ringtone playing confirmation message. In addition, the embodiment of the invention also provides polyphonic ringtone playing device and system. The invention effectively realizes the playing of an SIP polyphonic ringtone in the IP process of a CS domain.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a SIP-based color ring playing method, device and color ring playing system. Background technique [0002] The ring back tone (RBT, Ring Back Tone) service is usually provided by the communication operator. When the called party activates the ring back tone service, when the calling party calls the called party and waits to be connected, what he hears is no longer an ordinary reply. Instead of a ring tone, the normal ringback tone is replaced by pleasant music or a greeting. In the field of communication technology, circuit switched (CS, Circuit Switched) domain services are developing in the direction of IP, and traditional ring back tone services are usually implemented by user part (ISUP, ISDN User Part) signaling. However, ISUP signaling is not conducive to CS domain For IP-based services, the use of Session Initiation Protocol (SIP, Session Initiation Protocol) is mor...
