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.
