Method and device for determining information of mobile communication terminal, equipment and medium

Abstract

The invention relates to a method, device and equipment for determining information of a mobile communication terminal and a medium, and relates to the technical field of mobile communication, and the method comprises the following steps: sending a preset message message to a target mobile communication terminal; receiving a downlink signal; decoding the downlink signal based on a physical downlink control channel to obtain a wireless network temporary identifier and downlink control information corresponding to each wireless network temporary identifier; determining a target radio network temporary identifier matched with a preset data feature according to the downlink control information, wherein the preset data feature is related to the preset message; and determining the information corresponding to the target wireless network temporary identifier of the target uplink signal as the information belonging to the target mobile communication terminal according to the target wireless network temporary identifier. The modulation decoding difficulty of the feature matching locking target mobile communication terminal is reduced, the software development cost is saved, and the hardware cost is reduced.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method, device, device and medium for determining information of a mobile communication terminal. Background technique [0002] In order to distinguish the information of the target mobile communication terminal from the communication signal in the air, it is usually necessary to detect the wireless signal to confirm the target terminal according to the data characteristics. [0003] At present, the related technology of distinguishing the information of the target mobile communication terminal according to the data characteristics is mainly to decode the Physical Downlink Control Channel (PDCCH) first, and then perform the Physical Downlink Shared Channel (PDCCH) after obtaining relevant parameters. Physical Downlink Shared Channel, PDSCH) decoding to distinguish the information of the target mobile communication terminal; it is even necessary to fur...

AI Technical Summary

Problems solved by technology

[0004] The inventors found that PDSCH has high-order modulation, so when decoding PDSCH, there is a problem that the decoding of high-order modulation is difficult

[0005] In view of this, the present application provides a method, device, device and medium for determining the information of a mobile communication terminal, so as to solve the problem of high-level decoding and data decryption difficulty, so that the modulation and decoding difficulty of the target mobile communication terminal is reduced by feature matching , save software development costs, and reduce hardware costs
