1. An apparatus, comprising:
- a network controller operatively coupled to a resource controller via a SIP interface link, the network controller operatively coupled to a first SIP server via a SIP interface link and a SIP conference control interface link;
the network controller operatively coupled to at least one further SIP server via a signaling interface link;
the resource controller operatively coupled to network resources via a predetermined interface link;
the network resources operatively coupled to a first media server via a media interface link;
the first media server operatively coupled to the first end user via a first respective user equipment media interface link; and
the network resources operatively coupled to at least one further media server via a further media interface link;
wherein the network controller and the SIP servers exchange call control information, and wherein the network controller is operatively coupled to the media servers;
wherein the network controller and the resource controller exchange resource control information, the resource controller operatively coupled to network resources;
wherein the network controller employs a session description protocol within SIP to exchange resource control information with the resource controller using third party call control procedures; and
wherein media of a conference call between respective users is communicated over a bearer path between the network controller and the media servers, and wherein the network resources provide media translations between respective users.

Abstract
The apparatus and method are fast network SIP/SDP (Session Initiation Protocol/Session Description Protocol) procedures for conference operations upon request from end user with optimization of network resources. The apparatus has an SIP/SDP based network controller that, upon a received request, joins first and second calls into a conference call with at least a third call. The SIP/SDP based network controller is structured to negotiate, allocate and re-configure network resources.
