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.
