    • In one embodiment, a scheme is disclosed for managing delivery of a Mobile-Terminated (MT) call via an IMS network, wherein the MT call is originated by a calling party towards a User Equipment (UE) device that is CS-attached. An IMS-capable network node is operable to associate the received call information with an IP Multimedia Routing Number (IMRN) and provide the call information and the IMRN via alternative signaling (e.g., USSD or SMS messaging) to the UE device. A Mobile-Originated (MO) call process is initiated by the UE device using the received IMRN as the destination number, which terminates at the network node. Upon verifying that the returned IMRN is valid, the network node bridges the access and remote legs to establish the end-to-end path for the MT call between the UE device and the calling party.
    • 在一个实施例中,公开了用于经由IMS网络管理移动终止(MT)呼叫的传送的方案,其中,所述MT呼叫由主叫方发起朝向CS附着的用户设备(UE)设备。 具有IMS能力的网络节点可操作以将所接收的呼叫信息与IP多媒体路由号码(IMRN)相关联,并且经由替代信令(例如,USSD或SMS消息)向UE设备提供呼叫信息和IMRN。 移动发起(MO)呼叫过程由UE设备使用接收到的IMRN作为终止于网络节点的目的地号码发起。 在验证返回的IMRN是否有效时,网络节点桥接接入和远端,以建立UE设备和主叫方之间的MT呼叫的端到端路径。
