<p>The invention relates to a method for the optimized transmission of multimedia services in mobile communications networks, notably mobile telephone networks. The invention relies on the fact that, unless the complexity of the transmission system is increased, the bit error rate of especially the air interface is considerably higher than that of comparable fixed connections. However, at least at the level of the air interface transmission methods can be optimized with regard to spectrum economy (transmission bandwidth) and transmission quality if specifically optimized transmission methods are used for the different application-specific data structures such as speech, synchronous data transmission, image transmission, data packet transmission or message transmission, as is, for example, specified in the GSM network in the form of services. The invention aims to provide a solution to the above transmission problems. To this end one device each is placed on either side of the transmission sections concerned. Said devices communicate with each other and divide an integrated multimedia data flow into its application-specific data structures, transport the individual segments via transmission channels of the mobile telephone network which have been specially optimized for this particular purpose and then merge said segments to a transparent data flow which is identical to the original one.</p> |
