1. A system for implementing a multi-party conference service (MPCS) using broadcast/multicast service of a wireless communications system, comprising:
a conference focus of a multi-party conference service;
a broadcast/multicast service controller;
at least one mobile terminal; and
at least one content providing server which provides content media flow to the at least one mobile terminal,
wherein the conference focus receives media flow information related to a media flow from the at least one content providing server, and sends the received media flow information to the broadcast/multicast service controller,
wherein the conference focus receives broadcast/multicast service session information to establish a broadcast/multicast service session generated based on the media flow information of the broadcast/multicast service controller,
wherein the conference focus generates the context of a corresponding broadcast/multicast service session based on the received media flow information, multicast service session-related information and MPCS-related information, and
wherein the conference focus sends the generated context of the broadcast/multicast service session to the at least one content providing server, the at least one mobile terminal and the broadcast/multicast service controller so that the at least one mobile terminal obtains the content media flow through the broadcast/multicast service session.
