Efficient Data Transmission Multiplexing in 3g Mobile Systems

The 3G-324M is a derivative of the ITU-T H.324 standard which is for low bit rate multimedia communication. H.324 and several mobile specific annexes are usually referred to as H.324M (M stands for mobile). Then the 3GPP adopted the H.324M with some modifications in codecs and error handling requirements to create the 3G-324M standard. In order to support enhanced and delay sensitive video services, 3G video phones as well as network equipments are required to support 3G-324M. In 3G-324M, ITU-T H.223 defines the data transmission multiplexing protocol. We present an efficient approach for data transmission multiplexing of mobile terminals in this article. The original complicated nested structures of multiplex descriptor are serialized into simple linked list. As a result, we have achieved efficient implementations for both Intel Pentium Processor and ARM Processor, which proved the feasibility of our approach. The performance of our implementation is also satisfactory.
