Methods of managing terminal performed in base station and terminal

Abstract

Provided are methods of managing a terminal in a heterogeneous network (HetNet) environment. Between the methods, a method of managing a terminal performed in a base station includes determining whether or not a measurement change request event has occurred, and when a measurement change request event has occurred, transmitting a control message for instructing a change of a measurement operation to the terminal. Accordingly, it is possible to improve a measurement operation and discontinuous reception (DRX) operation control procedure necessary for connection control between one or more base stations and a terminal in a HetNet environment, and thereby performance of a system can be improved.

AI Technical Summary

Benefits of technology

This patent is about a way to manage a device in a network that uses different types of equipment. The method helps improve the performance of mobile communication, control interference, and ensure that the device's service is always available. It also reduces the device's power consumption by allowing it to selectively measure and reporting based on its own needs, and by performing different types of operations based on network conditions.

Problems solved by technology

Also, the quality of a radio channel deteriorates due to interference at a cell boundary, and radio link failure (RLF) occurs due to the deterioration, so that the overall performance of a mobile communication system is hindered.
