    • A communications network configuration for delivery of multimedia services comprises a packet network to which a plurality of terminal devices are connected, a service provider network for providing multimedia services to the terminal devices, a virtual circuit switched network intermediate the packet and service provider networks, and a gateway distributed over the circuit switched network. The distributed gateway comprises a client application unit interfacing the circuit switched network to said packet network and a virtual channel interface unit interfacing the circuit switched network to the service provider network. The client application unit binds logical channels for a multimedia call to association tags for respective virtual channels of the circuit switched network and forwards said association tags to the virtual interfacing unit. The interfacing unit assigns to the multimedia call one or more virtual channels associated with the association tags and informs the client application unit of channel numbers for the assigned channels to thereby complete set up of the multimedia call.
    • 用于传送多媒体服务的通信网络配置包括多个终端设备连接到的分组网络,用于向终端设备提供多媒体服务的服务提供商网络,分组和服务提供商网络中间的虚拟电路交换网络,以及 分布在电路交换网络上的网关。 分布式网关包括将电路交换网络接口到所述分组网络的客户端应用单元和将电路交换网络与服务提供商网络接口的虚拟通道接口单元。 客户端应用单元将用于多媒体呼叫的逻辑信道绑定到电路交换网络的相应虚拟信道的关联标签,并将所述关联标签转发到虚拟接口单元。 接口单元向多媒体呼叫分配与关联标签相关联的一个或多个虚拟信道,并向客户应用单元通知所分配的信道的信道号,从而完成多媒体呼叫的建立。
