Background

Currently, operators have online video polyphonic ringtone service, and audio polyphonic ringtone. The video color vibration service requires that when receiving an incoming call from a terminal device of a calling user (which may be called a calling terminal), the terminal device of a called user (which may be called a called terminal) is in an idle state, the called terminal should support display and play of video color vibration at the ringing stage of audio and video calls according to the video color vibration media negotiation requirement, and support recovery of the call between the calling user and the called user according to the requirement. The video color ring service requires that the calling terminal should support the display and play of the video color ring at the ringing stage of the audio and video calls and support the recovery of the calls between the calling and the called according to the requirements of the negotiation of the video color ring media under the condition that the called terminal is in an idle state when the calling terminal receives an incoming call.

Generally, after the called user transacts the video ring back tone service or the video ring back tone service, if a Single Radio Voice Call Continuity (SRVCC) handover occurs at any one of the terminals (the calling terminal or the called terminal) during the call ringing phase of the calling user or the call ringing phase of the called user, that is, the terminal device needs to switch from a fourth generation mobile communication technology (4G) network system or a fifth generation mobile communication technology (5G) network system to a second generation mobile communication technology (2G) network system or a third generation mobile communication technology (3G) network system, the video cannot be continuously played at the calling terminal, for example, the video ring back tone cannot be continuously played at the calling terminal, but rather to play the audio color ring; the called terminal can not play the video color vibration continuously, but can change to play the incoming call ring.

For ease of understanding, the following briefly introduces terms referred to in the embodiments of the present application.

1. Video color vibration: the called user transacts the business in the operator, the terminal ring of the called user is replaced by a section of video. The video color vibration function requires that the called terminal is in an idle state when receiving an incoming call from the calling terminal, and the called terminal supports the display and play of the video color vibration at the ringing stage of audio and video calls and supports the recovery of the calls between the calling and the called as required according to the negotiation requirement of the video color vibration media.

2. Video color ring back tone: the terminal ring back tone of the calling subscriber is replaced by a video segment in the service handled by the called subscriber in the operator. The video color ring function requires that the calling terminal should support the display and play of the video color ring at the ringing stage of the audio and video calls and support the recovery of the calls between the calling and the called according to the requirements under the condition that the called terminal is in an idle state when the calling terminal receives the incoming call.

3. Audio color ring back tone: the terminal ring back tone of the calling subscriber is replaced by a section of audio in the service handled by the called subscriber in the operator. The audio color ring function requires that the calling terminal should support the display and play of the audio color ring at the ringing stage of audio and video calls and support the recovery of the calls between the calling and the called according to the requirements of the negotiation of the video color ring media under the condition that the called terminal is in an idle state when receiving the call from the calling terminal.

4. SRVCC switching: SRVCC mainly solves the problem how to keep the continuity of voice service when a single radio frequency terminal device is switched from a 4G network system or a 5G network system to a 2G network system or a 3G network system, namely, the single radio frequency terminal device is seamlessly switched between VoIP voice and CS voice controlled by IMS.

It should be understood that, in the embodiments of the present application, the terminal device of the calling user is referred to as a calling terminal, and the terminal device of the called user is referred to as a called terminal. It should be understood that the calling terminal and the called terminal are named for the convenience of calling and called, and should not limit the functions of the terminal device itself. The calling party and the called party are corresponding, the calling terminal may also become the called terminal of other users, and the called terminal may also become the calling terminal of other users. This is not a limitation of the present application.

Taking video polyphonic ringtone as an example, at present, an operator network supports a user to upload at most 10 videos as video polyphonic ringtone per month through music application software (APP), and view and set a play rule through the music APP. After the user transacts the video color ring service, at least one video color ring can be set on the music APP of the operator to replace the ring back tone of the terminal. The video polyphonic ringtone function can also refer to the setting rule of the video polyphonic ringtone subsequently.

Illustratively, if the called user sets a video lottery for the terminal, the terminal can play the set video lottery when there is an incoming call.

For example, if the called user sets a plurality of video lottery tickets for the terminal, the terminal may randomly select one video lottery ticket from the plurality of video lottery tickets to play when there is an incoming call.

Illustratively, if the called user does not set a video lottery for the terminal, the terminal may randomly play one or more default video lottery when there is an incoming call, and the played video lottery is a season-good video periodically changed by the operator.

Generally, after a called user transacts a video color ring service or a video color ring service, if any one of terminals (a calling terminal or a called terminal) in the call ringing stage of the calling user or the call ringing stage of the called user has SRVCC handover, the terminal device cannot continue playing video online, for example, the calling terminal cannot continue playing video color ring, but instead changes to playing audio color ring, so that a video picture disappears, which may cause trouble to the user; the called terminal can not play the video color vibration continuously but changes to play the incoming call ring, so that for the same incoming call, the incoming call prompt tone of the terminal equipment is the video color vibration firstly, and then changes to the incoming call ring, and the user may fail or have problems for the transacted video color vibration service, which may cause troubles to the user.

In view of this, embodiments of the present application provide a video playing method and a video playing apparatus, so that a terminal device locally caches received video data or pre-stores video data, so that the terminal device provides a continuous video service for a user when SRVCC handover occurs, and user experience is improved.

Accordingly, the terminal device receives the first negotiation request message.

Illustratively, the first negotiation request message is an update (update) message, and the update message may include an early-media (early-media) field, which indicates that the network device may normally transmit video data if the field is "sendrecv".

S506, the terminal device sends a link establishment response message to the network device, where the link establishment response message is used to confirm establishment of a link that can transmit video data. Accordingly, the network device receives the link establishment response message.

Illustratively, the link that can transmit the video data is a link with a QoS Class Identifier (QCI) of 2(QCI 2), and the QCI 2 link is used for carrying video traffic.

In this step, the current QoS status may be "sendrecv," which indicates that a bearer is established and the terminal device may normally transmit video data. The QoS expected state may be "sendrecv" indicating that the terminal device expects to transmit video data normally. It should be appreciated that the bearer may be the QCI 2 link described above.

It should be understood that the second negotiation request message includes the audio video media parameters such as a PT value, a port number, a coding format, a coding rate, etc. that have been negotiated for playing the video lottery.

S508, the network device sends a second negotiation response message to the terminal device. Accordingly, the terminal device receives the second negotiation response message.

Alternatively, the network device may update the QoS current status and the QoS desired status of the network device and the terminal device.

Illustratively, the second negotiation request message is an update 200 OK message, and an SDP message of the update 200 OK message includes the updated QoS current status and QoS desired status of the network device. In this step, the current QoS status may be "sendrecv," which indicates that the bearer is established and the network device may normally transmit video data.

Illustratively, the first network standard is a 4G network standard or a 5G network standard, and the second network standard is a 2G network standard or a 3G network standard.

S513, under the condition that the switching from the first network system to the second network system is triggered, the terminal device circularly plays the video color vibration generated by the cached video data on the incoming call interface, or plays the local existing video of the terminal device.

The local video of the terminal device is the local video prestored in the memory of the terminal device before the ringing of the call.

It should be understood that the terminal device may trigger the switching of the network system, and may switch successfully or fail, which is not limited in this embodiment of the present application.

And under the condition that the terminal equipment triggers switching from the first network system to the second network system, the terminal equipment plays the video color vibration generated by the cached video data on the incoming call interface or plays the local existing video of the terminal equipment. Therefore, the trouble that the video playing is switched to the audio playing for the user due to the switching of the network modes can be avoided, and the continuous video playing experience is favorably brought for the user, so that the use experience of the user is improved.

It should be understood that fig. 5 is described above by taking the example of the terminal device as a called terminal to receive an incoming call. Similarly, when the terminal device is used as a calling terminal, the terminal device may send a call request through the network device, and perform audio and video media resource negotiation of the video polyphonic ringtone with the network device to obtain video data. After negotiation, the terminal device may play a video coloring ring back tone generated from the video data on the call interface. Similarly, under the condition that the terminal equipment triggers to switch from the first network system to the second network system, the terminal equipment plays the video color ring generated by the cached video data on a call interface or plays the local existing video of the terminal equipment. Therefore, continuous video playing experience is brought to the user, and the using experience of the user is improved.
