6.1 Control ASP
ASPs for configuring/controlling the SS are defined to operate in a pair of ASPs, Req (request) ASP and Cnf (Confirm) ASP of the blocking mode. The TTCN-3 execution after sending a Req ASP shall wait (be blocked) for the Cnf ASP.
Because the IMS Test Suite is radio access technology independent, few parameters are passed from the TTCN-3. Therefore the exact configuration procedures used are determined by the implementation.
The PIXIT px_RANTech (see below) is set by the operator according to the technology the UE supports and is passed through the TTCN to the SS. This is defined as an enumerated type and is used to specify which platform the test is to be run on (e.g. GERAN, UTRA or E-UTRA). Unless otherwise specified, E-UTRA shall be chosen if it is supported by the UE.
