Abstract
Air interface independent bearer data is provided in short message service delivery point-to-point (SMSDPP) invoke communications. The bearer data of the SMSDPP invoke communication includes a portion formatted for each of the different types of cellular network supported air interfaces. The particular portion of the bearer data corresponding to the air interface currently being used by that addressee mobile station is then processed to recover the included short message service message. Alternatively, the bearer data of the SMSDPP invoke communication is generically formatted, with the generic bearer data converted by the cellular network to be compatible with the specific one of the plurality of different types of air interfaces supported by the cellular telephone network based on an identification made by the cellular telephone system as to which air interface is currently being used by the addressee mobile station. Upon receipt, that addressee mobile station processes the converted beared data to recover the included short message service message.
