Abstract:
A method for evaluating a presentation layer data unit, which contains application-oriented messages, coded according to a predefined coding protocol for at least one application process running on a Q3 platform, the method comprising the steps of:receiving the presentation layer data unit by the Q3 platform via an association established on a Q3 interface between the Q3 platform and a partner Q3 platform; checking a format of the data unit for compliance with the predefined coding protocol; determining if there are any errors in the coding; if there are no errors in the coding, decoding user data contained in the data unit, determining the application-oriented messages, and forwarding the application-oriented messages to the appropriate application processes; and if there are errors in the coding, terminating the evaluation of the presentation layer data unit, sending the corresponding error report to the application process concerned, generating an error response, via the application process, to the coding error in the form of an application error message, and sending the error response to the partner Q3 platform.
