Problems solved by technology

However, for the weak coverage area or no coverage area in the communication network, due to the poor communication signal quality, the corresponding S ·ServingCell· ·intrasearch· or S ·ServingCell· ·intrasearch· If it is established, it means that the triggering condition of intra-frequency cell reselection measurement or inter-frequency / different-system cell reselection measurement is met. At this time, the terminal will perform the corresponding intra-frequency cell reselection measurement operation or inter-frequency / different system cell reselection measurement. operation, but the terminal cannot find the same-frequency adjacent cell or different-frequency / different-system adjacent cell suitable for handover or reselection, that is, the corresponding reselection measurement will not cause the terminal to substantially switch or reselect.
[0011] From the above description, it can be seen that in weak coverage areas or no coverage areas, although the corresponding cell reselection measurement operation process cannot select a better camping or serving cell for the terminal, the corresponding cell reselection measurement process is still frequently triggered Execution, causing the terminal to repeatedly perform invalid cell reselection measurement operations, which will inevitably increase the invalid power consumption of the terminal, thereby reducing the standby time of the terminal

Embodiment 1

[0079] In this embodiment, the validity measurement parameter of the cell reselection measurement may indicate the extent to which the wireless signal strength of the adjacent cell meets the requirements of cell reselection or handover during the current cell reselection measurement process, that is, the wireless signal strength of the adjacent cell The signal strength meets the degree of cell reselection or handover and determines the time length information required for the subsequent cell reselection measurement results to meet the handover or reselection conditions; specifically, in this embodiment, the RSRP / RSRQ measurement value of the neighboring cell can be The difference obtained after subtracting the sum of the RSRP or RSRQ measurement value of the serving cell and the hysteresis value (usually 3dB) (the difference value is a value less than zero) is used as the validity measurement parameter of the cell reselection measurement.

[0080] Specifically, taking the appli...

Embodiment 2

[0098] In this embodiment, a plurality of corresponding predetermined time intervals are respectively set according to corresponding validity measurement parameters, so that in the process of determining the time interval from the current cell reselection measurement to the next cell reselection measurement, more finely According to different levels of the obtained validity measurement parameters, the time interval from the current cell reselection measurement corresponding to the level to the next cell reselection measurement is set. In this way, the time interval from the current cell reselection measurement to the next cell reselection measurement can be more accurately and reasonably determined according to the validity measurement parameter setting. This enables the terminal to switch to a cell with good service quality in time, and can also reduce the possibility that the terminal performs invalid cell reselection measurement.

[0099] In this embodiment, it is assumed t...

Embodiment 3

[0114] In this embodiment, the location change information of the terminal is used as a corresponding validity measurement parameter as an example for description. Specifically, the location change information of the terminal is determined according to the mobile situation of the terminal, for example, the location change information of the terminal is measured and determined according to the moving speed of the terminal or the number of handovers or cell reselections of the terminal per unit time. That is to say, in this embodiment, the corresponding validity measurement parameters can be described by the mobile speed information of the terminal or the number of handovers or cell reselections of the terminal per unit time, so as to determine how long to perform the next cell reselection at intervals The measurement operation will most likely obtain cell reselection measurement results that meet the reselection or handover conditions, and set the measurement interval in combina...

Abstract

The invention discloses a method, a device and a terminal device for reselecting and measuring a cell. The method comprises the following steps: firstly, confirming an effective measuring parameter for reselecting and measuring the cell, wherein the effective measuring parameter is used for indicating the information of time period required for the condition that the result of the next reselecting and measuring of the cell meets a switching or reselecting condition; confirming the information of triggering time of the next reselecting and measuring of the cell according to the corresponding effective measuring parameter; and triggering an operation of reselecting and measuring the cell on the basis of the information of triggering time. According to the embodiment of the invention, by monitoring the effective measuring parameter for reselecting and measuring the cell, the triggering time for reselecting and measuring the cell is adjusted, so that the possibility of performing an invalid operation for reselecting and measuring the cell by a terminal is reduced to a certain extent, the consumption of invalid electric energy of the terminal is effectively reduced, the electric energy of the terminal is saved and the stand-by time of the terminal is prolonged.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and terminal equipment for cell reselection measurement. Background technique [0002] In a wireless communication system, in order to improve the communication quality of the terminal and ensure that the terminal can carry out communication services based on the cell with the best signal quality as much as possible, the cell that is most suitable for its communication is usually selected for the terminal by performing the corresponding cell reselection process. The serving cell or the cell where the terminal is camped on. [0003] Taking the cellular network system as an example, during the mobile process, the terminal will select the cell with the best signal as the current resident cell, or as the handover target cell, so as to obtain better communication effect in the subsequent communication process. In the process of cell reselection...
