1. A method for establishing a wireless data transfer connection between a remote application and a controlling application, where the wireless link from the remote application is implemented by a wireless terminal connected to the remote application, the method comprising: arranging a group of allowable connection parameter settings in a pre-determined order, each connection parameter setting corresponding to a different service bearer; attempting to use a default connection parameter setting, wherein the default connection parameter setting corresponds to a default service bearer; detecting that the default service bearer is not usable to establish a wireless data transfer connection; serially selecting another connection parameter setting for the wireless link from the group of allowable connection parameter settings in the pre-determined order one-after-another until a usable service bearer is identified to perform the wireless data transfer; and after identification of the usable service bearer and a successful wireless data transfer, setting the default connection parameter setting to the usable service bearer.
