And S230, when the calling terminal supports the video color ring service, the P-CSCF/SBC at the calling terminal side forwards a first notification message to the called terminal.
The first notification message may characterize a session type. For example, when the first notification message is selected as the INVITE message in SIP, and the contact header field in the INVITE message contains video, it is determined that the calling terminal supports the video color ring service.
S240, when the called terminal receives the first notification message, a second notification message is generated.
The second notification message may be a type of notification message for notifying the calling terminal side terminal that the call is in progress. For example, the second notification message may be selected as a 183 message in SIP, and in the present network, when the called terminal receives the INVITE message, the 183 message is generated according to SIP.
S250, the called terminal sends a second notification message to the called terminal side CRBT server.
S260, the called terminal side server inserts the video color ring playing configuration information into the second notification message to obtain a third notification message.
And the called terminal side server inserts the video color ring playing configuration information into the second notification message, so that a third notification message can be obtained. For example, the third notification message may be selected as a message formed by inserting the video color ring playing configuration information into the 183 message.
S270, the called terminal side server sends a third notification message to the calling terminal side P-CSCF/SBC.
The third notification message may be a type of notification message for notifying the calling terminal side terminal that the call is in progress and the video color ring play configuration. The calling terminal side P-CSCF/SBC is connected with the called terminal side server in a communication way, and the calling terminal side P-CSCF/SBC and the called terminal side server can directly transmit and receive third notification messages.
S280, the calling terminal side P-CSCF/SBC identifies the video color ring playing configuration information in the third notification message.
The calling terminal side P-CSCF/SBC can identify the video color ring playing configuration information in the third notification message based on the information identification algorithm, and the existing mature information identification algorithm can be used for information identification and is not described herein.
S290, the calling terminal side P-CSCF/SBC sends the video color ring playing configuration information to the policy and charging rule function/policy control function fusion network element PCRF/PCF.
The PCRF/PCF is in communication connection with the P-CSCF/SBC, and the PCRF/PCF and the P-CSCF can directly transmit video color ring playing configuration information.
And S200, the PCRF/PCF coordinates the core network to establish video bearing between the calling terminal and the core network according to the video color ring play configuration information.

According to the embodiment of the application, the third notification message is obtained by inserting the video color ring playing configuration information into the second notification message, and the PCRF/PCF can coordinate the core network to establish video bearing between the calling terminal and the core network according to the video color ring playing configuration information because the third notification message comprises the video color ring playing configuration information. Compared with the prior video color ring service, after the media bearer establishment is completed, the video color ring media negotiation process needs to cause PCRF/PCF to coordinate the core network to reestablish the video special bearer.
In one embodiment, the method may further comprise:
s270, the P-CSCF/SBC at the calling terminal side sends a notification message without deleting the video bearer to the PCRF/PCF when forwarding the first notification message to the called terminal.
In one embodiment, the notification message of not deleting the video bearer may be used to instruct the PCRF/PCF not to delete the video bearer during the period from receiving the notification message of not deleting the video bearer to receiving the video color ring media negotiation message.
After the media bearer is established, the PCRF/PCF automatically deletes the video bearer according to the SIP because the video bearer is not needed, and the video bearer can be prevented from being deleted based on the notification message of not deleting the video bearer.
In one embodiment, the method may further comprise:
s280, deleting the video color ring playing configuration information in the third notification message to obtain a fourth notification message.
S290, a fourth notification message is sent to the calling terminal.
The fourth notification message may be a type of notification message for notifying the calling terminal side terminal that the call is in progress. For example, the fourth notification message may be selected as the 183 message, and since the calling terminal can only identify the SIP message, in order to notify the calling terminal that the call is in progress, the video color ring playing configuration information in the third notification message is deleted, and the remaining fourth notification message belongs to the SIP message, so that the calling terminal can identify that the call is in progress.
In one embodiment, the third notification message may include:
session initiation protocol SIP message header field messages or SIP messages based on extensible markup language XML formatted message bodies.
When the called terminal side server and the calling terminal side P-CSCF/SBC communicate and transmit, a third notification message can be transmitted by adopting a SIP message header field message, specifically, a private header field P-video-Prediction is inserted into the second notification message, wherein the third notification message comprises 4 parameters:

(2) VideoCatCode: video color ring codec names, such as H.263/H.264;
(3) VideoFrameRate: video color ring frame rate, e.g., 10/15/24/25/30 frames/sec;
(4) Videocatanalysis: video color ring resolution, such as VGA/720P.
The P-CSCF/SBC directly sends the AAR message in the SIP to the PCF/PCRF according to the video CatBund width, requests the bandwidth of the video bearer, or calculates the bandwidth according to VideoCatCode, videoCatCode, videoCatResolution, and then sends the AAR message to the PCF/PCRF.
When the called terminal side server and the calling terminal side P-CSCF/SBC communicate and transmit, the SIP of the extensible markup language XML format message body can be adopted to transmit a third notification message, and a private header field (video call prediction) is inserted into the second notification message, wherein the information form is as follows:
<VideocatPrediction>

<VideoCatCode>H.263</VideoCatCode>
<VideoFrameRate>30</VideoFrameRate>
<VideoCatResolution>VGA</VideoCatResolution>
</VideocatPrediction>。
