Abstract

The invention discloses a method and a device for determining a terminal measurement frequency in a cell handover, relates to the technical field of radio communication, and provides a scheme for optimizing the terminal measurement frequency, which can reduce the measurement frequency of the terminal as much as possible on the premise of ensuring the success rate of the cell handover. The method provided by the embodiment of the invention comprises acquiring a first distance from the terminal to an evolved node base (eNB) of a service cell when the terminal moves from the service cell to a target cell and when the terminal is in accordance with handover conditions for the first time; and acquiring a critical distance from the terminal to the eNB of the service cell; calculating to obtain a handover effective distance by using the difference between the critical distance and the first distance; and determining the measurement frequency of the terminal according to the handover effective distance.

Description

Method and device for determining terminal measurement frequency during cell handover technical field The invention relates to the technical field of wireless communication, in particular to a method and a device for determining a terminal measurement frequency during cell switching. Background technique The Long Term Evolution (LTE) network is a flat wireless network, which is composed of the evolved base station (evolvedNodeBase, eNB) and the evolved packet switching center (EvolvedPacketCore , EPC) composition. A Mobility Management Entity (MME) in LTE will connect multiple eNBs. User equipment (User Equipment, UE) can move back and forth between multiple eNBs, which is the mobility of UE in LTE. Mobility is a very important feature in the LTE system. UE can achieve mobility through cell handover in connected state and cell reselection in idle state. When the UE switches from the current cell to the target cell, the UE needs to measure the power of the detected cel...
