    • In order to facilitate a handoff between a legacy circuit switched network (110) and a packet data network (120), such as a 3GPP LTE, 3GPP2 UMB, or WiMAX network, of a communication session anchored in an IMS Voice Call Continuity Application Server (VCC AS) (158), a Circuit Switched Proxy (CS Proxy) (132) is provided in the packet data network that communicates with a Mobile Switching Center (MSC) (118) of the circuit switched network. The CS Proxy allows the packet data network to communicate with the VCC AS, the MSC to communicate with the packet data network, and the MSC to communicate with the VCC AS via the packet data network, thereby allowing an exchange of handoff-related information between the packet data network and the VCC AS, the packet data network and the circuit switched network, and the circuit switched network and the VCC AS via the packet data network.
    • 为了促进传统电路交换网络(110)和锚定在IMS语音呼叫连续性应用服务器(IMS)中的通信会话的分组数据网络(120)(诸如3GPP LTE,3GPP2 UMB或WiMAX网络)之间的切换 (VCC AS)(158),在与电路交换网络的移动交换中心(MSC)(118)通信的分组数据网络中提供电路交换代理(CS代理)(132)。 CS代理允许分组数据网络与VCC AS通信,MSC与分组数据网络进行通信,MSC通过分组数据网络与VCC AS通信,从而允许分组数据网络之间交换切换相关信息 分组数据网络和VCC AS,分组数据网络和电路交换网络,以及电路交换网络和VCC AS经由分组数据网络。
