S220, the calling terminal side P-CSCF/SBC judges whether the calling terminal supports the video color ring service according to the first notification message.
The first notification message may characterize the session type. For example, when the first notification message is selected as an INVITE message in the SIP, and when a contact header field in the INVITE message contains video, it is determined that the calling terminal supports the video polyphonic ringtone service.
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 the session type.

S240, when the called terminal receives the first notification message, it generates a second notification message.
The second notification message may be a type of notification message for notifying the calling terminal side that the call is in progress. For example, the second notification message may be 183 message in SIP, and in the current network, when the called terminal receives the INVITE message, the 183 message is generated according to SIP.
And S250, the called terminal sends a second notification message to the color ring server at the called terminal side.
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 as to obtain a third notification message. 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 that the terminal is calling and configured for playing the video ring back tone. The calling terminal side P-CSCF/SBC is in communication connection with the called terminal side server, and the calling terminal side P-CSCF/SBC and the called terminal side server can directly receive and send the third notification message.
S280, the calling terminal side P-CSCF/SBC identifies the video color ring playing configuration information in the third notification message.
The P-CSCF/SBC at the calling terminal side may identify the video polyphonic ringtone playing configuration information in the third notification message based on an information identification algorithm, and the existing mature information identification algorithm may be used for information identification, which is not described herein again.
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 integrated network element PCRF/PCF.
And the PCRF/PCF is in communication connection with the P-CSCF/SBC, and the PCRF/PCF and the P-CSCF/SBC can directly transmit video CRBT playing configuration information.
S200, the PCRF/PCF coordinates the core network to establish the video bearing between the calling terminal and the core network according to the video color ring playing configuration information.

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 the video bearer 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 art that after the establishment of the media bearer is completed by the video color ring service, the video color ring media negotiation process needs to cause the PCRF/PCF to coordinate the core network to reestablish the video proprietary bearer, the embodiment of the application directly coordinates the core network to establish the video bearer between the calling terminal and the core network according to the video color ring playing configuration information, does not need secondary bearer establishment, shortens the call delay, and avoids the problem of call failure caused by the video bearer reestablishment failure.
In one embodiment, the method may further comprise:
s270, when the calling terminal side P-CSCF/SBC forwards the first notification message to the called terminal, the notification message of not deleting the video bearer is sent to the PCRF/PCF.
In an embodiment, the notification message not deleting the video bearer may be used to instruct the PCRF/PCF to not delete the video bearer during a period from the reception of the notification message not deleting the video bearer to the reception of the video ringback tone media negotiation message.
After the conventional voice call without video is established in the media bearer, 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 that the video bearer is not deleted.
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.
And S290, sending a fourth notification message to the calling terminal.
The fourth notification message may be a type of notification message for notifying the calling terminal side that the terminal call is in progress. For example, the fourth notification message may be 183 message, because the calling terminal can only identify the SIP message, in order to notify the calling terminal that the call is in progress, the video polyphonic ringtone 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 are in communication transmission, an SIP message header field message may be used to transmit a third notification message, specifically, a private header field "P-video-Prediction" is inserted into the second notification message, which includes 4 parameters:
