Abstract: Delay in IMS call establishment and other time critical data transfers may be reduced by seeking alternative transmission methods for time critical data, when a transmission cannot be completed or the Radio Access Technology is otherwise unavailable. A Critical Service Manager (“CSM”) receives and evaluates priority information about a given data transfer. By evaluating this priority information, the CSM can identify priority data, or latency intolerant data, such as IMS calls or emergency calls. Where network rejects a connection request and issues a wait timer, the CSM may lower the retransmission count to hasten a permanent transmission failure. Upon a permanent transmission failure, the CSM can determine an alternative protocol for transmission of the priority data, such as transmitting data through circuit switch fallback, via Wi-Fi, or through another legacy RAT.

Abstract: A communication device and a method to perform a switch from a first radio access technology (RAT) to a second RAT consisting of detecting multiple pending transactions to be conducted on the second RAT, switching from the first RAT to the second RAT, conducting the multiple pending transactions on the second RAT, and implementing a restriction on switching back to the first RAT for at least the duration while the multiple transactions on the second RAT is taking place.

Abstract: Apparatuses and computer-readable storage media for handling timers for mobile terminated circuit-switched fallback (MT CSFB) calls. An apparatus for a user equipment (UE) includes processing circuitry operably coupled to a data storage device. The data storage device is configured to store a value of an extended service request for mobile terminated services (EXT-MT) timer. The value of the EXT-MT timer is less than a value of a guard timer of a Visitor Location Register (VLR). The processing circuitry is configured to start the EXT-MT timer and generate an extended service request message to be transmitted to a Mobility Management Entity (MME) responsive to a paging for an MT CSFB call, and attempt to select a radio access technology of a different type of network if the EXT-MT timer expires before the UE successfully performs inter system change and a circuit switched fallback cancellation request was not received from a subscriber.
