    • The present invention discloses a node (207, 217) for achieving co-existence of single radio voice call continuity, SR-VCC, solutions in a communication system between a source cell of a first radio access network that supports packet switched voice and a target cell of a second radio access network that supports at least circuit switched voice. The node (207, 217) is operable to perform bearer splitting by separating voice bearers from non-voice bearers based on information about support for dual transfer mode, packet switched handovers and voice over internet protocol related enhancements in the target cell.
    • 本发明公开了一种用于实现单无线语音呼叫连续性的共存的节点(207,217),SR-VCC,支持分组交换语音的第一无线接入网络的源小区与目的地之间的通信系统中的解决方案 至少支持电路交换语音的第二无线电接入网络的小区。 节点(207,217)可操作以通过基于关于双目标小区中的双传输模式,分组交换切换和基于因特网协议的语音支持的信息,将语音承载与非语音承载分离来执行承载分裂。
