The IMS domain coloring ring back tone SIP routing trigger brief description:
the IMS domain color ring triggering mainly follows 3GPP 24.182 protocol specification, a called IMS domain triggering principle is adopted, when a request (Invite) message initiated by a calling IMS domain is sent to a called IMS domain S-CSCF, the called S-CSCF triggers a color ring server through Initial Filter Criteria (iFC) signing information of a user, after the color ring server processes, a calling message returns to the S-CSCF, and a subsequent calling process is continued. The color ring server starts a playback flow to the calling user after receiving the called ringing message (180), and when the called user is off-hook, the color ring server initiates a Re-request (Re-Invite) flow to complete the media negotiation between the calling and called users and finally complete the conversation between the calling and called users.
In the prior art, only after a called video color ring user goes off-hook or when a call is automatically ended due to long-time non-connection, the video color ring is finished playing, and the user experience of the video color ring is influenced. In the technical scheme of the invention, the method and the device for controlling the video color ring in the call are provided, so that the calling user can close the video color ring and return to the traditional playback mode in the calling process, the service flow of the video color ring is perfected, and the user experience of the video color ring is improved. Based on the existing video color ring calling process, the invention defines the process of closing the video color ring by utilizing the existing SIP message process. One method is that the calling UE sends a request message for closing the video color ring in the call to the color ring server, and the color ring server responds to the request, closes the video color ring and informs the calling UE to play the traditional ring back tone. The other is that the calling UE sends a request message for closing the video color ring to the color ring server, the color ring server responds to the request, closes the video color ring and informs the telephone application server (network side), and then the telephone application server informs the calling UE to play the traditional ring back tone. Compared with the two methods, the second method is that the telephone application server informs the calling UE to play the traditional ring back tone, and can support the network side to play the ring back tone.
The technical solution of the present invention is described below by way of examples. The following description takes an audio call as an example, but any other type of communication service or multimedia service, such as a video call, is also applicable.
Fig. 2 is a schematic diagram illustrating an embodiment of a method for controlling a video polyphonic ringtone in a call according to an embodiment of the present invention. The method for controlling video color ring in a call provided by the embodiment of the present invention can be applied to the application scenario provided in fig. 1, and is described with a CAT AS a color ring server in the following embodiment drawings. The embodiment of the invention comprises the following steps:
201. calling UE initiates a call to called UE and completes resource reservation of the calling UE and the called UE; 202. the calling UE and the color ring server finish the process of the audio/video color ring media SDP negotiation; 203. the calling UE plays the color ring; 204. closing the color ring; 205. playing the conventional ringback tone.
The specific signaling steps are described as follows:
201. calling UE initiates a call to called UE and completes resource reservation of the calling UE and the called UE;
specifically, the method can comprise the following steps:
1-4: the calling UE sends out a call request, i.e., a request (Invite) message, which includes a Session Description Protocol (SDP) of the calling UE; after receiving the request, the CSCF network element of the called IMS domain forwards the Invite message to a color ring application server CAT AS according to an initial filter rule (iFC rule) configured for the user by an operator; after completing the message processing, the CATAS returns the processed Invite message to the CSCF; the CSCF continues to execute the iFC rule and forwards the Invite message to a Telephony Application Server (TAS); after the TAS finishes the message processing, returning the processed Invite message to the CSCF; the CSCF forwards the Invite message to the called UE;
5-8: the called UE receives the Invite message and returns a 183 message. The 183 message indicates that the called UE has received the call request message, and the 183 message includes the called SDP. 183 the message will be sent to the calling UE along the path followed by the Invite message;
9-12: the calling UE sends a confirmation (PRACK) message to the called UE, which indicates that the 183 message is received;
13-16: the called UE returns a 200OK message to the calling UE, wherein the 200OK message carries PRACK information and indicates that the called side has received the PRACK message; the calling UE receives a 200OK message;
17-23: the calling UE sends an Update (Update) message to the called UE, which indicates that the calling side completes the construction of the media channel. The called side returns 200OK message to the calling side. The flow of the section is in a Gateway Precondition mode, and the flow of the section is not in the Gateway no-Precondition mode;
24-26: the called UE sends a 180 message to the CSCF indicating that the called UE has started ringing. The CSCF forwards the 180 message to the TAS and CAT AS.
202. The calling UE and CAT AS finish the negotiation process of the audio/video color ring back tone media SDP. Specifically, the method can comprise the following steps:
27-30: after receiving the 180 message, the CAT AS sends an Update message to the calling UE, wherein the Update message carries audio/video color ring media SDP information, and the audio/video color ring media SDP information can also be called audio/video color ring media negotiation information; calling UE receives an Update message, if the calling UE supports audio/video color ring back tone media, audio/video media negotiation is carried out according to audio/video color ring back tone media SDP information carried in the Update message and media capability information of the calling UE, an audio/video media negotiation result is determined, and a 200OK message is sent to CAT AS, wherein the audio/video media negotiation result is carried in the 200OK message;
it should be understood that the audio/video media negotiation result is carried by SDP protocol, and the audio/video media negotiation result includes, but is not limited to, information of the audio/video polyphonic ringtone media supported by the calling UE, information of the internet protocol IP address of the audio/video media received by the calling UE, information of the audio/video channel port number, and information of the audio/video coding/decoding.
In an exemplary form, a description is made of video color ring SDP information as follows:
v-0/protocol version information, here using SDP version number 0 × @

203. And the calling UE plays the color ring. Specifically, the method can comprise the following steps:
31-32: the CAT AS sends 180 messages to the calling UE. CAT AS sends video color ring media to calling UE, and the calling UE plays the video color ring.
204. And closing the color ring. Specifically, the method can comprise the following steps:
33-34: the calling UE sends a request message for closing the video color ring to the CAT AS, and carries an indication for closing the video color ring. The request message may be an Update message, where the SDP in the Update message duplicates the content of the audio/video polyphonic ringtone media SDP negotiation, and sets the port numbers of the audio media description m line and the video media description m line in the SDP content to 0, which is used as an indication for closing the video polyphonic ringtone.
For example, in the video polyphonic ring tone SDP information, the audio media description line m ═ audio 34318RTP/AVP 104 and the video media description line m ═ video 5098RTP/AVP 102 are modified to m ═ audio 0RTP/AVP 104 and m ═ video0RTP/AVP 102, respectively.
35-36: after the CAT AS receives the Update message, when the Update message carries an indication of closing the video polyphonic ringtone, that is, the port numbers of the audio media description m line and the video media description m line in the SDP content of the Update message are both set to 0, the CAT AS determines that the message is a request message for closing the video polyphonic ringtone. CAT AS stops sending audio/video media stream and stops playing video color ring. And CAT AS sends 200OK message to calling UE, and responds to the closing request of calling UE. The calling UE stops playing the video color ring.
205. Playing the conventional ringback tone may specifically include:
if the current call adopts a mode of playing the ring back tone at the local terminal, CAT AS sends 180 information to the calling party, wherein PEM (action) carried in the 180 information indicates that the network side does not play the ring back tone and indicates the calling UE to play the traditional ring back tone; if the current call adopts the mode of playing the ring back tone at the network side, the CAT AS and the calling UE carry out SDP media negotiation again, namely, the calling UE plays the traditional ring back tone and carries out media negotiation. The media negotiation result includes, but is not limited to, information of audio media supported by the calling UE, and the calling UE receives information of an internet protocol IP address, an audio channel port number, and audio coding/decoding information of the audio media. After the SDP negotiation is completed, the CAT AS sends 180 information to the calling UE, where the 180 information carries PEM inactive, which indicates that the network side does not play the ring back tone any more, and the calling UE plays the traditional ring back tone. Optionally, the CAT AS may send the 180 message to the calling party, where the 180 message carries SDP information of the CAT AS, directly initiate SDP offer negotiation, perform SDP media negotiation with the calling UE, and after the negotiation is completed, the calling UE plays the conventional ringback tone.
In the embodiment of the invention, after the calling UE initiates a call and plays a video color ring, the calling UE sends a request message for closing the video color ring in the call to the color ring server, the color ring server responds to the request, closes the video color ring, and the color ring server informs the calling UE to play a traditional ring back tone. The invention solves the limitation that the video color ring can be finished only after the called UE is off-hook or the calling is automatically finished because the calling is not connected for a long time.
Fig. 3 is a schematic diagram illustrating another embodiment of a method for controlling a video polyphonic ringtone in a call according to an embodiment of the present invention. In the embodiment of the present invention, 301 to 304 correspond to 201 to 204 in fig. 2, and respectively complete the resource reservation, audio/video media negotiation, color ring playing, and video color ring closing processes for initiating an audio call, which are not described herein again. The following describes in detail the flow of playing the conventional ringback tone.
305. Playing the conventional ringback tone. Specifically, the method can comprise the following steps:
37-38: the CAT AS sends INFO message to TAS, informing TAS (network side) to take over the play of the ring back tone of the calling UE. The INFO message contains the number of the calling party and the called party. And the TAS receives the INFO message and finds out the corresponding call session for closing the video color ring according to the calling number and the called number in the INFO message.
If the current call adopts a mode of playing the ring back tone at the local terminal, the TAS sends 180 information to the calling UE, wherein PEM (action) carried in the 180 information indicates that the network side does not play the ring back tone and indicates the calling UE to play the traditional ring back tone; if the current call adopts the mode of playing the ring back tone at the network side, the TAS and the calling UE carry out SDP media negotiation again, namely, the calling UE plays the traditional ring back tone and carries out media negotiation. The media negotiation result includes, but is not limited to, information of audio media supported by the calling UE, and the calling UE receives information of an internet protocol IP address, an audio channel port number, and audio coding/decoding information of the audio media. After the SDP negotiation is completed, the TAS sends 180 messages to the calling UE, where the 180 messages carry PEM sendonly, which indicates that the network side plays a ring back tone, and the TAS plays a conventional ring back tone for the calling UE. Optionally, when the TAS sends the 180 message to the calling party, the 180 message carries SDP information of the TAS, and directly initiates SDP offer negotiation, and performs SDP media negotiation with the calling UE, and after the negotiation is completed, the TAS plays a traditional ring back tone for the calling UE.
In the embodiment of the invention, the calling UE sends a request message for closing the video color ring in the call to the color ring server, the color ring server responds to the request, closes the video color ring, informs the TAS (network side), and then takes over the calling UE to play the traditional ring back tone by the TAS, thereby realizing the function of actively closing the video color ring by the calling. Compared with the embodiment shown in fig. 2, the TAS is introduced for processing, and the network side can be supported to play the ring back tone.
Fig. 4 is a schematic diagram illustrating another embodiment of a method for controlling a video polyphonic ringtone in a call according to an embodiment of the present invention. In the embodiment of the present invention, 401 to 403 correspond to 301 to 303 in fig. 3 and 201 to 203 in fig. 2, which are processes of initiating an audio call to complete resource reservation, audio/video media negotiation and playing a color ring, respectively, and are not described herein again. The following describes the process of closing ring back tone.
404. And closing the color ring. Specifically, the method can comprise the following steps:
33-34: see 33-34 in FIG. 2, which are not described herein.
35-36: after the CAT AS receives the Update message, when the Update message carries an indication of closing the video polyphonic ringtone, that is, the port numbers of the audio media description m line and the video media description m line in the SDP content of the Update message are both set to 0, the CAT AS determines that the message is a request message for closing the video polyphonic ringtone. In this embodiment, the CAT AS may further query the relevant authority configuration to determine whether the video color ring is closed. The authority configuration can be derived from the called user subscription information, for example, in the process of registering the called user, the called user subscription information is called by the TAS telephone application server and stored locally. If the permission configuration allows the video color ring to be closed, the CAT AS closes the video color ring, responds to a 200OK message, and informs the calling UE to play the traditional ring back tone, and the specific signaling flow refers to FIG. 2, or informs a TAS (network side) and is taken over by the TAS to play the traditional ring back tone for the calling UE, and the specific signaling flow refers to FIG. 3; if the user configuration information does not allow the video color ring to be closed, the CAT AS sends an error prompt to the calling UE to inform the calling UE that the video color ring is failed to be closed, for example, an error message is answered 606, and a warning header field carries a video RBT always open.
In the embodiment of the invention, after receiving a request message for closing the video color ring of a calling UE, a color ring server inquires related authority configuration, and performs a process of closing the video color ring when the authority allows the video color ring to be closed; and when the authority does not allow the video color ring to be closed, informing the calling UE that the closing fails. Compared with the embodiments shown in fig. 2 and fig. 3, the method and the device consider the permission problem of video color ring back tone closing, so that the video color ring back tone service function is more complete. For example, when an enterprise subscribes to the video ring back tone service as an enterprise advertisement or an operator advertises the advertisement by using the video ring back tone service, the video ring back tone is not desired to be closed by the calling UE.
