A computer implemented method and system for maximizing a number of connections that can be executed from a mobile application is disclosed. The method comprises determining whether a connection slot is available for a received call request; executing the call when a connection slot is available; processing the call request when a connection slot is not available, where processing comprises: determining a priority level for the request; when the determined priority level is a low priority, putting the request in a queue for later processing; and when the determined priority level is a high priority, when a low priority call is in progress, performing the steps of: canceling the in-progress low priority call; placing the cancelled low priority call in a queue for later processing; and executing the high priority call; and when no low priority call is in progress, placing the high priority call request in the queue.
