A New Bi-processor SmartPhone Evaluation of the perfomance generating GPRS and UMTS data traffic

Vol. 6  No. 3  pp. 47-56


In this work a new type of device is introduced: a bi-processor SmartPhone equipped with a network interface GSM/GPRS/EDGE/UMTS. The architecture used, with two processors, is introduced to take advantage of the subdivision of the functionalities provided by the two processors. A better distribution of various functions is achieved, all above when multi-media traffic is considered. Moreover, the interaction between the two processors has to be realized in a convenient manner to better take advantage of the sub-division. The form of communication established between the two processors chosen is serial communication based on the standard RS232 and ETSI 07.10. Before realizing the product we propose to evaluate the performance of a similar project. To do this a simulator was built focusing our attention on communication between the two processors and different types of data traffic (voice call, sms, etc.). were generated. Furthermore, GPRS and UMTS connections were considered on our simulator to verify that a similar architecture, when correctly developed and dimensioned, can support this type of data traffic. To be sure about the effectiveness of our simulator this was validated through a statistical method, associating a queue model both with GPRS data traffic and UMTS data traffic.
