Nowadays, network positioning technology 3GPP partnership project, using the infrastructure of mobile radio networks, most widely implemented in networks of 4G/LTE standard and ensure positioning accuracy of user devices (UE) in the tens of meters. An order of magnitude higher positioning accuracy in 5G NR networks, from the national economy point of view, is the subject of medium to long term perspective. The relevance of technical solutions for UE positioning in deployed 4G/LTE networks is due to inability to confidently receive signals from global navigation satellite systems in dense urban development scenarios. In the first part of the study on 4G network positioning technologies, the architecture of user device positioning system using LTE mobile radio network infrastructure is formalized.
