Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for updating a conference call media access type.
Background
VOLTE (Voice over LTE, IMS-based Voice service) is an IP data transmission technology, that is, an audio/video call is performed through an IP Multimedia Subsystem (IP Multimedia Subsystem) network of an LTE access operator. The existing VOLTE conference call is realized in such a way that a conference chairman party and a conference participant party are both connected with a conference center, wherein the conference call refers to simultaneous conversation of a plurality of people created, managed and terminated by the conference chairman, and the conference center refers to a server for providing conference call service by a network terminal. When a chairman of a conference carries out video upgrading or voice degrading operation, negotiation with a conference center is needed, whether other conference participants need to upgrade videos or degrade voices at the moment depends on whether the conference center requires a local strategy of upgrading videos or degrading voices, and other conference participants cannot participate in the negotiation process, so that the final negotiation result cannot be obtained; when the conference participants perform video upgrading or voice degrading operation, the conference participants also need to negotiate with the conference center directly, the conference chairman party cannot control the process, and meanwhile, the conference center does not inform the conference chairman party of the current media types of the conference participants, so that the conference chairman party cannot know the media types of all the conference participants accessing the teleconference in real time.
Therefore, the existing VOLTE conference telephone has the defect that the media types of other current participants cannot be known by both the conference chairman party and the conference participants.

when the media access type applied for modification is degraded to voice, the conference center receives voice access acceptance messages sent by all corresponding conference participants;
when the media access type applied for modification is upgraded to video, the conference center receives video access acceptance messages or video access rejection messages sent by all corresponding conference participants;
and the conference center sends a first media updating notification message carrying the media access types of the chairman party and all the conference participants to the chairman party and all the conference participants.
In a second aspect, the present invention provides an apparatus for updating media access type of a conference call, where the apparatus includes a chairman party, at least one conference participant and a conference center;
