Original Abstract

The key problem of modern mobile packet-oriented networks is adaptation of QoS, Qual-ity of service. For complex and reliable control of QoS, the appropriate measurements are needed. For exact and authentic measurement of absolute size of traffic delay, it is abso-lutely necessary to detect correct time offset between mobile station and corresponding server. According to the consequential research, the service should be functional with any Java enabled mobile phone and in any situation when the signal quality for data transfers is sufficient. Only way how to achieve this goal is to adapt existing standards, or propose new one, which will be able to provide efficient time synchronization over high-latency data networks using application layer only.
