A cell measurement method for saving terminal energy

Abstract

A cell measuring method saving terminal energy comprises the following step: first, enhancing or setting a terminal function to realize the following operations: after two terminals, which are in the same service mode and closer to each other in the same cell, are in D2D connection, only one of the two terminals is responsible for periodically measuring the signals of the cell or adjacent cells until the terminal executes the cell reselection or switchover, or the two terminals are not in D2D connection; under the two different conditions, the terminal responsible for the cell measuring informs the other terminal of restarting periodically measuring the signals of the cell or the adjacent cells; the terminals in the D2D connection have two modes: a connection mode and an idle mode, so that the method also has two different measuring operation processes. The method can reduce the energy consumption of the terminals, reduce the signaling processing load of a base station, and reduce the cost of network maintenance and management.

Description

technical field [0001] The present invention relates to an energy-saving technology, that is, a cell measurement method that saves terminal energy; to be precise, it relates to a method for using a D2D communication mechanism to assist a terminal to measure signals in its own cell or an adjacent cell, so as to reduce terminal energy consumption; it belongs to wireless The technical field of communication. Background technique [0002] In a cellular communication network, cell measurement is one of the important physical layer processes. The user terminal periodically measures the signals of its own cell and / or neighboring cells to select the best serving cell, so as to realize related functions of mobility management. [0003] According to different connection states of user services, the user terminal needs to perform different cell measurement procedures. Specifically, for a terminal in the connected mode, it is necessary to periodically measure the received signal power...

AI Technical Summary

Problems solved by technology

For connected mode terminals, the measurement results must be periodically reported to the base station, which undoubtedly greatly wastes terminal energy, reduces the service life of terminal batteries, increases the processing load of the base station, and increases the cost of network construction and maintenance.

Moreover, for the cell where the terminal in the connected mode is located, since the measurement report shares channel resources with other uplink signaling, the capacity of other uplink signaling is reduced
