Embodiment Construction
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but 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.
[0033] Firstly, it should be pointed out that during the drive test, the reason why the reselection lag occurs during the movement of the drive test terminal may be that the drive test terminal moves too fast. When the drive test terminal is in a high-speed mobile scenario, the time for the drive test terminal to pass through the handover area may be shorter than the handover processing time, so the corresponding handover process cannot be completed, re...

The present invention provides a method for controlling the reselection of a drive test terminal cell, a drive test method, a device, and a drive test instrument, wherein the method for controlling the reselection of a drive test terminal cell includes: when the drive test terminal meets the preset requirements for cell reselection condition, determine whether the speed of the road test vehicle equipped with the road test terminal is greater than the first preset speed threshold; when the speed of the road test vehicle is greater than the first preset speed threshold, control the speed of the road test vehicle to be less than a second preset speed threshold; sending a cell reselection instruction to the drive test terminal to control the drive test terminal to perform cell reselection; the first preset speed threshold is greater than or equal to the second preset speed threshold. The solution of the present invention can solve the problem of reselection lag when the drive test terminal is in a high-speed mobile scene, thereby ensuring that the drive test terminal has enough time to search for the optimal cell one by one for the frequency points, and the drive test results will not be affected by reselection. The problem of hysteresis becomes worse, thereby improving the accuracy of coverage optimization evaluation for wireless networks.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for controlling cell reselection of a drive test terminal, a drive test method, a device and a drive test instrument. Background technique [0002] With the development of communication technology, mobile communication is moving from the connection between people to the connection between people and things and between things. The Internet of Everything is an inevitable trend. As an evolutionary technology of Long Term Evolution (LTE), Narrow Band-Internet of Things (NB-IoT), also known as Cellular Internet of Things, has wide coverage, large connections, mobility and low power consumption. It will bring rich application scenarios and become the main connection technology of the Internet of Things. NB-IOT is mainly used in access scenarios with low transmission rate, static or low mobile rate. [0003] When planning and optimizing NB-IOT networks, drive testing i...
