Currently, along with the continuous upgrade of 4G bandwidth and the subsequent commercialization of 5G, the application of ViLTE and derivatives thereof has become more and more popular, and for example, unidirectional video (Uni-directional video) has been practically applied to a plurality of mobile terminal products supporting ViLTE as an application scheme meeting special requirements of users.
As an application scheme meeting special requirements of users, the unidirectional video needs to ensure user controllability of unidirectional video operation, that is, the direction of the unidirectional video cannot be changed before the user does not operate the unidirectional video. In practical use, in some network environments, during the duration of the unidirectional video, the network may synchronize call information with the UE by issuing a Re-invite without SDP message. According to the current 3GPP protocol TS24.628, for a call not in hold state, the direction of each media information in the SDP in the response message 200OK for the Re-invite with out SDP should be set to "sendrecv", and if the direction of the media information in the acknowledgement message ACK of the subsequent network reply is also "sendrecv", the operation of changing the state of the unidirectional video without the participation of the user is substantially completed, resulting in a substantial direction change, but the direction change is not permitted by the user, thus violating the user's will and not meeting the basic functional requirements of the unidirectional video itself.
