METHOD FOR REALIZING RADIO VIDEOCONFERENCE, SYSTEM AND TERMINAL THEREOF

摘要

A method for realizing a radio videoconference is provided by the present invention, which includes: an initiator radio access terminal (AT) initiates a conference request to a packet core network (PCN); the PCN initiates a conference invitation according to a list of invited parties of the conference carried by the received conference request, establishes and initializes radio resources for each AT attending the radio videoconference, and sends information for the conference members participating in the radio videoconference to the initiator AT which stores the information, so as to complete the establishment for the radio videoconference system; after establishing the radio videoconference system successfully, the PCN receives signaling streams from the AT in the radio videoconference system, and sends the received signaling streams to the initiator AT; the initiator AT sends control instructions to the PCN according to the signalings in the received signaling streams, and controls the PCN to distribute the information streams in the radio videoconference system. The present invention also discloses a system for realizing a radio videoconference and an AT. By applying the present invention, a multiparty radio videoconference can be implemented.
