PLANNING TO OPTIMIZE THE UMTS CALL SETUP FOR THE EXECUTION OF MOBILE APPLICATIONS

The third generation of mobile communication, the so-called UMTS, makes a broad variety of applications for mobile terminals available. This endeavor is the maintenance of several applications on one terminal: Radio bearers have restrictions in the quality of service (QoS) for applications due to limited resources. And the cell setup for the execution of several mobile applications may lead to unacceptable waiting periods for the user. As example considers WAP access, where the connection to the gateway takes, in general, approximately half a minute. This period increases if one is using several applications on one mobile terminal. Another hinderance is an insufficient QoS availability during the call setup. Here, the execution of the mobile application is shutdown.

In this paper, the optimization of the call setup for several mobile applications is investigated. The optimization applies scheduling to order and optimize the execution of the modules for UMTS for the call setup. This application is new for scheduling in artificial intelligence (AI). The premise is the modularization of the UMTS call setup based on agent technology, since the call setup of radio is basically a continuous process in the field of electrical engineering. As a result, the user has a shorter waiting period until the execution of several mobile applications is started and thus mobile terminals can be used more flexibly. Experiments for the execution of up to 20 mobile applications on the same mobile terminal demonstrate the optimization.
