Embodiment Construction

[0026] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] Embodiment 1 of the present invention provides a method for determining terminal measurement frequency during cell handover, see figure 1 , the method includes:

[0028] 11: When the terminal moves from the serving cell to the target cell, acquire the first distance from the evolved base station (evolved Node Base, eNB) of the serving cell when the terminal meets the handover condition for the first time; and,

[0029] 12: Obtain the critical distance between the terminal and the eN...

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

technical field [0001] 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 [0002] The Long Term Evolution (LTE) network is a flat wireless network composed of evolved Node Base (eNB) in the Evolved UMTS Terrestrial Radio Access Network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN) ) and Evolved Packet Core (EPC). [0003] One mobility management entity (Mobility Management Entity, MME) in LTE will connect multiple eNBs. User equipment (User Equipment, UE) can move back and forth among 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. [0004] When the UE switches from the current cell to the target cell, the UE needs to measure the power of the detected c...
