    • In one embodiment, a scheme is disclosed for routing a Session Initiation Protocol (SIP) call in a network environment including a circuit-switched (CS) network and an IP multimedia subsystem (IMS) network. When a SIP call is originated by a user equipment (UE) device in the CS network domain, call information associated with the call is provided to an application server (AS) node disposed in the IMS network. At the AS node, a pool of E.164 numbers are maintained as IP multimedia routing numbers (IMRNs) which are mapped to or otherwise associated with called party SIP URIs. The AS node dynamically allocates a select IMRN with respect to a called party's SIP URI received from the UE device and returns it to the UE device. The dynamically allocated IMRN is then utilized for routing the SIP call towards the called party.
    • 在一个实施例中,公开了用于在包括电路交换(CS)网络和IP多媒体子系统(IMS)网络的网络环境中路由会话发起协议(SIP)呼叫的方案。 当SIP呼叫由CS网络域中的用户设备(UE)设备发起时,与呼叫相关联的呼叫信息被提供给设置在IMS网络中的应用服务器(AS)节点。 在AS节点处,将E.164号码池作为IP多媒体路由号码(IMRN)进行维护,这些IP映射号码被映射到或与被叫方SIP URI相关联。 AS节点相对于从UE设备接收到的被叫方的SIP URI动态分配选择IMRN,并将其返回给UE设备。 然后,动态分配的IMRN用于将SIP呼叫路由给被叫方。

    • In one embodiment, a scheme is disclosed for managing call continuity in a network environment including a circuit-switched (CS) network and an IP multimedia subsystem (IMS) network wherein unique identity (ID) information supplied by a user equipment (UE) device is utilized. A pool of dynamically allocable IP multimedia routing numbers (IMRNs) maintained at an IMS network node are used for associating an IMRN with call information received from the UE device, which can include at least one of a GRUU, Instance ID, and the called party number relating to a call. When the dynamically allocated IMRN is returned by the UE device, the network node utilizes the IMRN mapping to effectuate call continuity with respect to the called party.
    • 在一个实施例中,公开了一种用于管理包括电路交换(CS)网络和IP多媒体子系统(IMS)网络的网络环境中的呼叫连续性的方案,其中由用户设备(UE)设备提供的唯一标识(ID)信息 被利用。 维护在IMS网络节点处的动态可分配IP多媒体路由号码池(IMRN)的池被用于将IMRN与从UE设备接收的呼叫信息相关联,呼叫信息可以包括GRUU,Instance ID和被叫方 有关电话的号码。 当由UE设备返回动态分配的IMRN时,网络节点利用IMRN映射来实现对被叫方的呼叫连续性。
