    • Methods, systems, and devices for facilitating mobility between flexible bandwidth systems and other bandwidth systems are provided. These tools and techniques that provide mobility between different bandwidth systems may facilitate supporting circuit-switched (CS) services, such as CS voice services. Some embodiments provide for determining flexible bandwidth capable devices, such as user equipment. Some embodiments involve core network redirection where a core network may direct the handling of circuit-switched services when a flexible bandwidth system does not support the CS services. Some examples provide for radio access network determined handling of CS services when a flexible bandwidth system may not support the CS services. Some embodiments provide for transitioning to a flexible bandwidth system. Some embodiments provide for transitioning from flexible bandwidth systems to non-flexible bandwidth systems that have no support for some or all CS services, other flexible bandwidth systems, and/or systems that natively support CS voice services.
    • 提供了用于促进灵活带宽系统和其他带宽系统之间的移动性的方法,系统和设备。 提供不同带宽系统之间的移动性的这些工具和技术可以促进支持诸如CS语音服务的电路交换(CS)服务。 一些实施例提供用于确定具有灵活带宽能力的设备,诸如用户设备。 一些实施例涉及核心网络重定向,其中当柔性带宽系统不支持CS服务时,核心网络可指导对电路交换服务的处理。 当灵活的带宽系统可能不支持CS服务时,一些示例提供确定的CS服务处理的无线接入网络。 一些实施例提供了转换到灵活带宽系统。 一些实施例提供从柔性带宽系统转换到不支持某些或所有CS服务的其他灵活带宽系统和/或本机支持CS语音服务的系统的非灵活带宽系统。
