    • The present invention relates to a method for a handover of a UE (User Equipment) currently engaged in a voice call. More particularly, the invention relates to a handover from 1) a packet based radio where Voice Service is provided via VoIP over the radio and is controlled via Session Initiation Protocol (SIP) based signalling (e.g. LTE, E-UTRAN or WIMAX radio) to 2) a radio access network where Voice Service can be only provided via circuit switched (CS) domain (a visited mobile switching centre (VMSC) is needed) such as legacy 3GPP UMTS Terrestrial Radio Access Network (UTRAN)/ GSM/Edge Radio Access Network (GERAN) coverage. A MSC-S entity acting as a Packet Core Control Node on a Packet Switched (PS) network and as an Anchor Visited Mobile Switching Centre (VMSC) for a handover to a Circuit Switched (CS) network on the CS domain side is proposed, the MSC-S preparing a new path with a remote UE-B and a CS domain handover towards a target legacy radio coverage before requesting a UE- A to execute the handover.
    • 本发明涉及一种当前正在进行语音通话的UE(用户设备)的切换方法。 更具体地,本发明涉及从1)基于分组的无线电的切换,其中通过无线电通过VoIP提供语音服务,并且通过基于会话发起协议(SIP)的信令(例如LTE,E-UTRAN或WIMAX无线电)来控制 2)无线​​接入网络,其中语音业务只能通过电路交换(CS)域(需要被访问的移动交换中心(VMSC))提供,例如传统的3GPP UMTS陆地无线电接入网(UTRAN)/ GSM /边缘无线接入 网络(GERAN)覆盖。 提出了在分组交换(PS)网络上作为分组核心控制节点的MSC-S实体以及用于在CS域侧切换到电路交换(CS)网络的锚定访问移动交换中心(VMSC) 在请求UE-A执行切换之前,MSC-S准备具有远程UE-B的新路径和朝向目标传统无线电覆盖的CS域切换。
