    • For an incoming session intended for a user element, a domain selection function (DSF) is provided in a multimedia subsystem (MS) to select a circuit-switched subsystem (CS) or MS domain to use when routing the incoming session to the user element. Regardless of the domain in which incoming sessions are originated, the incoming sessions intended for the user element are routed to an S-CSCF in the MS. The S-CSCF directly or indirectly employs the DSF to determine whether to use the MS or the CS for terminating the incoming session. Based on available domain selection criteria, the DSF will select an appropriate domain, such as the MS or CS, to use for routing the incoming session to the user element. The domain selection decision of the DSF is provided to the S-CSCF, which will proceed by routing the incoming session to the user element via the selected domain.
    • 对于用于用户元素的传入会话,在多媒体子系统(MS)中提供域选择功能(DSF),以选择在将传入会话路由到用户元素时使用的电路交换子系统(CS)或MS域 。 不管发起传入会话的域名,用于用户元素的传入会话路由到MS中的S-CSCF。 S-CSCF直接或间接地使用DSF来确定是否使用MS或CS来终止传入会话。 基于可用的域选择标准,DSF将选择适当的域,例如MS或CS,用于将传入会话路由到用户元素。 DSF的域选择决定被提供给S-CSCF,S-CSCF将通过所选择的域将入局进入路由到用户单元。
