Abstract: A scenario may arise in which a circuit switched (CS) bearer reservation is successful but a voice media switching from packet switched (PS) to CS performed by a mobile switching center (MSC) server fails. Certain embodiments provides systems, apparatuses, and methods for recovery from such a scenario. A method, for example, can include determining whether session transfer of a user equipment is possible in response to a request from a network element to initiate session transfer of the user equipment and reporting to the requesting network element either a generic or specific indication that the transfer is not possible, when it is determined that the session transfer is not possible.

Abstract translation: 可能出现一种情况，其中电路交换（CS）承载预留成功，但是由移动交换中心（MSC）服务器执行的从分组交换（PS）到CS的语音媒体切换失败。 某些实施例提供用于从这种场景中恢复的系统，装置和方法。 例如，一种方法可以包括确定用户设备的会话传输是否可能响应于来自网络元件的请求来发起用户设备的会话传送并且向请求的网络元件报告通用或特定的指示， 当确定会话转移是不可能时，不可能进行传输。
