Abstract
An ability to limit and manage the number of multiple radio access bearer (mRAB) initiations, which are transitions from a Circuit Switched (CS) voice session, is provided. Moreover, the system, within a Radio Access Network (RAN), can identify vulnerable radio conditions for a user equipment (UE) on an uplink (UL) and/or a downlink (DL), and then subsequently determines whether a Packet Switched (PS) data session is allowed to pass through to the UE, during a CS voice call. In addition, the system can temporarily block a network-initiated data request to the existing CS voice call, if the voice call is likely to be dropped on initiating an mRAB. As the vulnerable radio conditions improve, the system can deliver the previously blocked data request to the UE.
