b method to provide an establishment of calls quickly and flexu00ecvel; apparatus to stop providing a call set-up fast and flexu00ecvel; system for the establishment of calls; computational progru00e1ma product including a progru00e1ma to a processing device and chip s; Emicondutor d today, the time of establishment of calls, after the establishment of the channel carrier.In 3G systems - 324m is in the order of magnitude of ten to twenty seconds, is currently in the order of magnitude. The experience of the user is such that users have to wait 10 seconds or even longer to connect a call video phone to connect a voice call.Therefore, we need a technique to improve the time of establishment of calls. Several proposals have been made to the relevant corporations of standardization. The two most recent, which showed the greatest interest groups of standardization, are perhaps the fastmedia (FM) and the fast session setup (FSS).The fastmedia operates by pre spread the table multiplexadora of ITU-T Recommendation H.223 with operational points embedded in codes. If afastmedia fail (no in step 521), the technique before back to legacy and slows down the 11.245. According to the invention, instead of back to legacy and to retard the 11.245, a procedure known FSS, such as the establishment fast logical channel, if present, is executed (step S23).
