A method for implementing a wireless video conference, comprising: initiating, by an initiator Wireless Access Terminal, AT, a conference request to a Packet Core Network, PCN; performing, by the PCN, a conference invitation according to a conference inviter list included in the conference request, establishing a radio resource and performing initialization for each AT which attends the wireless video conference, and sending information of conference members attending the wireless video conference to the initiator AT for storing to complete an establishment of a wireless video conference system; receiving, by the PCN, a signalling flow of the AT in the wireless video conference system, after the wireless video conference system is established successfully, and sending the signalling flow to the initiator AT; and sending, by the initiator AT, a control command to the PCN, according to a signalling in the signalling flow, to control the PCN to distribute an information flow in the wireless video conference system, characterized in that, wherein the step of establishing the radio resource and performing initialization for each AT which attends the wireless video conference comprises: establishing, by the PCN, the radio resource for the initiator AT, after the PCN receives the conference request, and authenticates and authorizes the initiator AT successfully, sending Point To Point Protocol, PPP, initialization information to the initiator AT, and assigning an internet Protocol, IP, address to the initiator AT; establishing, by the PCN, a radio resource for an participant AT, after the PCN receives a conference participation command returned by the participant AT, sending the PPP initialization information to the participant AT, and assigning an IP address for the participant AT. initiating, by an initiator Wireless Access Terminal, AT, a conference request to a Packet Core Network, PCN; performing, by the PCN, a conference invitation according to a conference inviter list included in the conference request, establishing a radio resource and performing initialization for each AT which attends the wireless video conference, and sending information of conference members attending the wireless video conference to the initiator AT for storing to complete an establishment of a wireless video conference system; receiving, by the PCN, a signalling flow of the AT in the wireless video conference system, after the wireless video conference system is established successfully, and sending the signalling flow to the initiator AT; and sending, by the initiator AT, a control command to the PCN, according to a signalling in the signalling flow, to control the PCN to distribute an information flow in the wireless video conference system, characterized in that, wherein the step of establishing the radio resource and performing initialization for each AT which attends the wireless video conference comprises: establishing, by the PCN, the radio resource for the initiator AT, after the PCN receives the conference request, and authenticates and authorizes the initiator AT successfully, sending Point To Point Protocol, PPP, initialization information to the initiator AT, and assigning an internet Protocol, IP, address to the initiator AT; establishing, by the PCN, a radio resource for an participant AT, after the PCN receives a conference participation command returned by the participant AT, sending the PPP initialization information to the participant AT, and assigning an IP address for the participant AT. establishing, by the PCN, the radio resource for the initiator AT, after the PCN receives the conference request, and authenticates and authorizes the initiator AT successfully, sending Point To Point Protocol, PPP, initialization information to the initiator AT, and assigning an internet Protocol, IP, address to the initiator AT; establishing, by the PCN, a radio resource for an participant AT, after the PCN receives a conference participation command returned by the participant AT, sending the PPP initialization information to the participant AT, and assigning an IP address for the participant AT.
