Specifically, the target mobile communication terminal may refer to a mobile communication terminal that needs to be searched, such as a mobile phone that needs to be searched. Specifically, in the process of determining the mobile communication terminal information, the mobile communication terminal which needs to be currently searched may be used as the target mobile communication terminal, and a preset message may be sent to the target mobile communication terminal, so that the base station sends related information to the target mobile communication terminal according to the preset message, and the PDCCH data of the target mobile communication terminal presents preset data characteristics.

The characteristic matrix table may record various preset data characteristics related to the preset message, and specifically may include a message type corresponding to the preset message, message data size information, transmission block size information, and scheduling frequency information corresponding to the transmission block size information.

In a specific implementation, the embodiment of the application may summarize the feature matrix table by testing and/or counting data of a plurality of base stations for a plurality of times in real time, so that the target wireless network temporary identifier may be screened out by using information matching recorded in the feature matrix table in the following. Specifically, in the process of sending the preset message, the preset message may be sent to the target mobile communication terminal through the base station to generate a corresponding downlink signal, so that uplink transmission scheduling information and/or downlink transmission scheduling information related to the preset message may be recorded based on DCI information carried in the downlink signal, and a feature matrix table corresponding to the preset message may be generated based on the recorded uplink transmission scheduling information and/or downlink transmission scheduling information. The uplink transmission scheduling information may refer to transmission scheduling information related to an uplink signal, and specifically may include uplink transmission block size information and uplink scheduling frequency information corresponding to the uplink transmission block size information; the downlink transmission scheduling information may refer to transmission scheduling information related to a downlink signal, and may specifically include downlink transmission block size information and downlink scheduling frequency information corresponding to the downlink transmission block size information.

Further, the feature matrix table in the embodiment of the present application may specifically include: the message type, message data volume information, uplink transmission scheduling information and/or downlink transmission scheduling information; the uplink transmission scheduling information comprises uplink transmission block size information and uplink scheduling frequency information; the downlink transmission scheduling information includes downlink transmission block size information and downlink scheduling frequency information. It should be noted that, the message data size information may refer to a message content size of a preset message, for example, may be 1 kbit, 2 kbit, and the like, which is not limited in this embodiment of the application. The downlink transmission block size information may refer to a transmission block size corresponding to the radio network temporary identifier in the downlink signal; the downlink scheduling frequency information may refer to a scheduling frequency corresponding to a radio network temporary identifier in a downlink signal; the uplink transport block size information may refer to a transport block size corresponding to the radio network temporary identifier in the uplink signal; the uplink scheduling frequency information may refer to a scheduling frequency corresponding to the radio network temporary identifier in the uplink signal.

In the actual processing, the situations that the base station sends the message to the target mobile communication terminal can be specifically divided into three categories: the first type is that when the time-frequency resource of the base station is enough and the data volume of the message is not large (namely one transmission block can hold), the base station can directly use one transmission block to forward the message to the target mobile communication terminal after receiving the message; the second type is that when the time-frequency resource of the base station is enough but the data volume of the message is large (namely one transmission block can not be accommodated), the original data packet of the message can be split into a plurality of transmission blocks after the message is received and forwarded to the target mobile communication terminal, and the interval time between the plurality of transmission blocks is short; the third type is that when the time frequency resource of the base station is not enough, the original data packet can be split into a plurality of transmission blocks to be forwarded to the target mobile communication terminal after the message is received, and the interval time among the plurality of transmission blocks is longer.

According to the embodiment of the application, the characteristic matrix table of various message messages under the three types of conditions can be counted according to the characteristic matrix table obtained by multiple data measurement, various appointed message messages are sent and the size and scheduling frequency of a transmission block received by a tested mobile communication terminal, so that the characteristic matching can be carried out on the characteristic matrix table to determine the target RNTI matched with the preset data characteristic.

For example, in the case of sending a short message with a size of 1 kbit to a target mobile communication terminal, when a base station is idle, the PDCCH information carrying DCI for indicating downlink information of the target mobile communication terminal may be issued, where the DCI for indicating the downlink information of the target mobile communication terminal may indicate that a transmission block with a size of 1.1 kbit is used to transmit the short message serving as a preset message, that is, the 1 kbit short message is integrated into a transmission block with a size of 1.1 kbit and issued to the target mobile communication terminal, and meanwhile, the PDCCH information also carries DCI for indicating uplink information, where the DCI for indicating the uplink information of the target mobile communication terminal may indicate that the uplink information transmitted to the base station by the target mobile communication terminal is transmitted by a transmission block with a size of 0.9 kbit; when the base station is busy, the PDCCH information carrying two DCIs for indicating the downlink information of the target mobile communication terminal can be issued, each of the DCIs for indicating the downlink information of the target mobile communication terminal can indicate that a transmission block with 0.6K bit is used for transmitting a short message serving as a preset message, that is, the 1K short message is divided into 2 transmission blocks with 0.6K bit, so that the 1K short message is issued to the target mobile communication terminal through the 2 transmission blocks with 0.6K bit, and simultaneously, one of the DCI for indicating the uplink information carried by the PDCCH information can indicate that the transmission block with 1.1K bit is used for transmitting the uplink information transmitted by the target mobile communication terminal to the base station. Therefore, different transmission block sizes and scheduling frequencies may occur when preset message messages with the same size are sent; and the rules of different base stations are different, and a feature matrix table is obtained by summarizing and adjusting after testing or counting data of a plurality of base stations for a plurality of times in real time, as shown in the following table 1:

TABLE 1

It can be seen that the table tests the corresponding data characteristics when the type of the sent message is a short message and the data volume of the sent message is 1 kbit and 2 kbit respectively. By using the preset data characteristics recorded in the characteristic matrix table 1, a short message with the size of 1K bit can be sent to a target mobile communication terminal during application, the PDCCH is decoded, the scheduling frequency of each RNTI and the size of a transmission block indicated by DCI carried by the PDCCH corresponding to each RNTI are recorded, and then matching and screening can be performed in the preset characteristic matrix table according to the recorded scheduling frequency and the size of the transmission block corresponding to the scheduling frequency, so that RNTIs corresponding to the situation that the size of the transmission block and the scheduling frequency meet the first condition and the second condition in the above table (namely, the situation that the message type is a short message and the size of the message data amount is 1K bit) can be screened out, and further, RNTIs meeting the data characteristics of the first condition and the second condition in the above table can be determined as candidate RNTIs, so as to determine the target RNTI based on the candidate RNTIs. It is understood that if there is only one candidate RNTI, the candidate RNTI is the target RNTI.

As an example of the present application, after decoding is performed by using the PDCCH, downlink transport block size information, downlink scheduling frequency, uplink transport block size information, and uplink scheduling frequency of each RNTI in a downlink signal may be obtained based on downlink control information obtained after decoding, and then the downlink transport block size information and the downlink scheduling frequency of each RNTI may be used as a current data characteristic to be matched with the downlink transport block size information and the downlink scheduling frequency information recorded in the feature matrix table, so that when the downlink transport block size information of the RNTI is the same as the downlink transport block size information recorded in the feature matrix table, and the downlink scheduling frequency of the RNTI is the same as the downlink scheduling frequency information recorded corresponding to the feature matrix table, the RNTI is determined as a target radio network temporary identifier; or, the uplink transmission block size information and the uplink scheduling frequency of each RNTI can be used as current data characteristics to be matched with the uplink transmission block size information and the uplink scheduling frequency information recorded in the characteristic matrix table, so that when the uplink transmission block size information of the RNTI is the same as the uplink transmission block size information recorded in the characteristic matrix table, and the uplink scheduling frequency of the RNTI is the same as the uplink scheduling frequency information correspondingly recorded in the characteristic matrix table, the RNTI is determined as the target radio network temporary identifier; or, the uplink transport block size information and the downlink transport block size information, the uplink scheduling frequency, and the downlink scheduling frequency of each RNTI may be used as current data characteristics to match the transport block size information and the scheduling frequency information recorded in the feature matrix table, so that the uplink transport block size information of the RNTI is the same as the uplink transport block size information recorded in the feature matrix table, the downlink transport block size information of the RNTI is the same as the downlink transport block size information recorded in the feature matrix table, the uplink scheduling frequency of the RNTI is the same as the uplink scheduling frequency information recorded corresponding to the feature matrix table, and the downlink scheduling frequency of the RNTI is determined to be the target radio network temporary identifier when the downlink scheduling frequency of the RNTI is the same as the downlink scheduling frequency information recorded corresponding to the feature matrix table.

Optionally, on the basis of the foregoing embodiment, before sending the preset message to the target mobile communication terminal, the embodiment of the present application may further include: acquiring preset message content information, wherein the preset message content information comprises communication identification information of a target mobile communication terminal, and the communication identification information comprises an Internet Protocol (IP) address and a telephone number; and generating the preset message by adopting the preset message content information. The preset message content information may refer to preset message content; the communication identification information may refer to information that may be used to identify the mobile communication terminal, and may specifically include, but is not limited to: a phone number, an IP address, etc. of the destination mobile communication terminal, which is not particularly limited in this embodiment.

Referring to fig. 2, a flowchart of a method for determining information of a mobile communication terminal according to an alternative embodiment of the present application is shown. The method for determining the mobile communication terminal information provided by the embodiment of the application can comprise the following steps:

step 210, obtaining the preset message content information.

And step 220, generating a preset message by using the preset message content information.

Step 230, sending a preset message to the target mobile communication terminal.

In the actual processing, preset message content information such as a telephone number and an IP address of the target mobile communication terminal can be acquired to generate a corresponding preset message by using the preset message content information, and the preset message has a first preset data characteristic, so that the base station sends related information to the target mobile communication terminal according to the preset message, and the PDCCH data of the target mobile communication terminal presents the preset data characteristic, so that the subsequent characteristic matching can be performed based on the PDCCH data.

For example, the short message and the multimedia message need to acquire the telephone number of the target mobile communication terminal, and before sending the preset message to the target mobile communication terminal, the preset message is sent to the target mobile communication terminal according to the telephone number of the target mobile communication terminal, so that the preset message can be sent to the target mobile communication terminal through the telephone number, and the target mobile communication terminal can receive the preset message and reply the corresponding response message; for another example, the Ping packet needs to acquire an IP address of the target mobile communication terminal, and before sending the preset message to the target mobile communication terminal, the Ping packet serving as the preset message is sent to the IP address of the target mobile communication terminal according to the IP address of the target mobile communication terminal, so that the target mobile communication terminal receives the preset message and replies a corresponding response message. The response message may be a response message replied by the target mobile communication terminal after receiving the preset message, and the response message sends the relevant information to the base station according to the size of the transmission block and the scheduling frequency indicated by the DCI in the PDCCH information sent by the base station.

Further, the preset message in the embodiment of the present application may be used to trigger the target mobile communication terminal to send a response message. The method for determining the mobile communication terminal information provided by the embodiment of the application, after sending the preset message to the target mobile communication terminal, may further include: and receiving the response message. Specifically, after receiving a response message replied by the target mobile communication terminal for receiving the preset message, it may be determined that the target mobile communication terminal receives the preset message.

And 250, decoding the downlink signal based on a Physical Downlink Control Channel (PDCCH) to obtain radio network temporary identifications and downlink control information corresponding to each radio network temporary identification.

And step 260, determining a target wireless network temporary identifier matched with the preset data characteristics according to the downlink control information.

Wherein the predetermined data characteristic is associated with the predetermined message. Specifically, the transport block size and the modulation frequency of each RNTI in the downlink signal may be extracted from the downlink control information obtained after the PDCCH is decoded, so as to determine a target RNTI matched with the preset data characteristics based on the extracted transport block size and modulation frequency of the RNTI. Further, the determining the target radio network temporary identifier matched with the preset data characteristic according to the downlink control information may specifically include the following substeps:

substep 2601, extracting transport block size information and scheduling frequency information corresponding to each radio network temporary identifier in the downlink signal from the downlink control information;

and a substep 2602, matching according to the transmission block size information and the scheduling frequency information of each radio network temporary identifier to obtain a target radio network temporary identifier matched with the preset data characteristics.

Specifically, after the downlink control information is obtained, the downlink control information may be utilized to obtain the transport block size and scheduling frequency of each RNTI in the received downlink signal, and may be used as the current data characteristic of each RNTI, so as to match the transport block size information and scheduling frequency information of each RNTI with the preset data characteristic recorded in the preset characteristic matrix table, that is, match the current data characteristic of each RNTI with the preset data characteristic, for example, for each radio network temporary identifier, the transport block size information identical to the transport block size information of the radio network temporary identifier may be searched in the preset characteristic matrix table, and the searched identical transport block size information may be used as the preset transport block size information, and then the scheduling frequency information corresponding to the preset transport block size information in the characteristic matrix table may be used as the preset scheduling frequency information, comparing the scheduling frequency information with the scheduling frequency information of the wireless network temporary identifier, and determining the wireless network temporary identifier as a target wireless network temporary identifier when the preset scheduling frequency information is the same as the scheduling frequency information of the wireless network temporary identifier; for another example, for each radio network temporary identifier, scheduling frequency information that is the same as the scheduling frequency information of the radio network temporary identifier may be searched in a preset feature matrix table, the searched same scheduling frequency information may be used as preset scheduling frequency information, and transport block size information corresponding to the preset scheduling frequency information in the feature matrix table may be used as preset transport block size information, and compared with the transport block size information of the radio network temporary identifier, so that when the preset transport block size information is the same as the transport block size information of the radio network temporary identifier, the radio network temporary identifier may be determined as the target radio network temporary identifier.

In the actual processing, the preset data characteristics may include a combination of multiple sets of preset uplink and downlink transmission size information and preset uplink and downlink scheduling frequency information. When the size of the transmission block corresponding to the RNTI and the scheduling frequency satisfy one of the combinations, candidates can be entered, that is, the RNTI is taken as a candidate RNTI, so that a target RNTI with the highest matching degree can be determined according to the candidate RNTI in the following. The candidate RNTI can be used as a candidate item of the target radio network temporary identifier; if a candidate wireless network temporary identifier is matched, if a candidate wireless network temporary identifier can be matched according to the uplink transmission block size information and the uplink scheduling frequency information of the wireless network temporary identifier, the candidate wireless network temporary identifier can be directly determined as a target wireless network temporary identifier; if there are two or more matched candidate wireless network temporary identifications, for example, there may be two or more candidate wireless network temporary identifications matched according to the uplink transmission block size information and the uplink scheduling frequency information of the wireless network temporary identification, further matching may be performed according to the uplink transmission block size information and the uplink scheduling frequency information corresponding to the candidate wireless network temporary identification, so as to determine the target wireless network temporary identification.

As an example of the present application, after decoding is performed by using the PDCCH, downlink transport block size information, downlink scheduling frequency, uplink transport block size information, and uplink scheduling frequency of each RNTI in a downlink signal may be obtained based on downlink control information obtained after decoding, and then the downlink transport block size information and the downlink scheduling frequency of each RNTI may be used as a current data characteristic to be matched with the downlink transport block size information and the downlink scheduling frequency information recorded in the feature matrix table, so that when the downlink transport block size information of the RNTI is the same as the downlink transport block size information recorded in the feature matrix table, and the downlink scheduling frequency of the RNTI is the same as the downlink scheduling frequency information recorded corresponding to the feature matrix table, the RNTI is determined as a candidate radio network temporary identifier; or, the uplink transmission block size information and the uplink scheduling frequency of each RNTI can be used as current data characteristics to be matched with the uplink transmission block size information and the uplink scheduling frequency information recorded in the characteristic matrix table, so that when the uplink transmission block size information of the RNTI is the same as the uplink transmission block size information recorded in the characteristic matrix table, and the uplink scheduling frequency of the RNTI is the same as the uplink scheduling frequency information correspondingly recorded in the characteristic matrix table, the RNTI is determined to be a candidate radio network temporary identifier; or, the uplink transport block size information and the downlink transport block size information, the uplink scheduling frequency and the downlink scheduling frequency of each RNTI may be used as current data characteristics to match with the transport block size information and the scheduling frequency information recorded in the feature matrix table, so that the uplink transport block size information of the RNTI is the same as the uplink transport block size information recorded in the feature matrix table, the downlink transport block size information of the RNTI is the same as the downlink transport block size information recorded in the feature matrix table, the uplink scheduling frequency of the RNTI is the same as the uplink scheduling frequency information recorded corresponding to the feature matrix table, and the downlink scheduling frequency of the RNTI is the same as the downlink scheduling frequency information recorded corresponding to the feature matrix table, and the RNTI is determined as the candidate radio network temporary identifier. Then, the number of the candidate radio network temporary identifications can be counted, if the number of the candidate radio network temporary identifications is one, namely when the downlink scheduling frequency information of only one RNTI is matched with the preset data characteristics, the candidate radio network temporary identifications can be directly determined as target radio network temporary identifications; if the number of the candidate radio network temporary identities is greater than one, that is, when the downlink scheduling frequency information of two or more RNTIs is matched with the preset data characteristics, uplink and/or downlink transport block size information and uplink and/or downlink scheduling frequency information of each candidate radio network temporary identity may be obtained, the uplink and/or downlink transmission block size information and the uplink and/or downlink scheduling frequency information temporarily identified by each candidate wireless network are matched with the uplink and/or downlink transmission scheduling information recorded in the feature matrix table, and further, when the size information of the uplink and/or downlink transmission block and the uplink and/or downlink scheduling frequency information of the candidate wireless network temporary identifier are matched with the uplink and/or downlink transmission scheduling information recorded in the feature matrix table, the candidate wireless network temporary identifier can be confirmed as the target wireless network temporary identifier. When the size information of the uplink and/or downlink transmission block and the uplink and/or downlink scheduling frequency information of the candidate wireless network temporary identifier are not matched with the uplink and/or downlink transmission scheduling information recorded in the characteristic matrix table, the candidate wireless network temporary identifier can be ignored, if the candidate wireless network temporary identifier is not confirmed as the target wireless network temporary identifier, the characteristic matching accuracy is improved, and the target mobile communication terminal searching efficiency is improved.

And 270, determining the information corresponding to the target wireless network temporary identifier as the information belonging to the target mobile communication terminal according to the target wireless network temporary identifier.

Specifically, after the preset message is sent, if a target radio network temporary identifier is determined by using the data characteristics decoded by the PDCCH, the information corresponding to the target radio network temporary identifier may be determined as the information that the target mobile communication terminal is determined as belonging to the target mobile communication terminal, so that the target mobile communication terminal may be subjected to corresponding service processing according to the information corresponding to the target radio network temporary identifier; if two or more target wireless network temporary identifications are confirmed by using the data features decoded by the PDCCH, the preset message can be sent to the target mobile communication terminal again until one target wireless network temporary identification matched with the preset data features is matched. Further, when the number of the target radio network temporary identifiers is greater than one, the method for determining the mobile communication terminal information provided by the embodiment of the present application may further include: and repeatedly sending a preset message to the target mobile communication terminal until a target wireless network temporary identifier matched with preset data characteristics is determined according to the downlink control information.

Specifically, when a plurality of devices are in a preset range, that is, a plurality of mobile communication terminals (devices) are in the preset range, the received uplink and downlink signals include a plurality of downlink signals and a plurality of uplink signals, and further, the extracted downlink signal PDCCH data characteristics include a plurality of downlink signals, that is, a plurality of radio network temporary identifiers obtained by decoding based on a physical downlink control channel are provided, and then, the extracted downlink signal PDCCH data characteristics can be matched with the preset data characteristics to determine the downlink signal PDCCH data characteristics matched with the preset data characteristics. When there are multiple downlink PDCCH data features matching the preset data features, the process may return to step 230 to execute, so as to send the preset message to the target mobile communication terminal again until one downlink PDCCH data feature matching the preset data features is included, and determine the radio network temporary identifier corresponding to the downlink PDCCH data feature as the target radio network temporary identifier, so as to determine the information corresponding to the target radio network temporary identifier as the information belonging to the target mobile communication terminal.

When the preset message is sent to the target mobile communication terminal again, the same preset message as the previous preset message may be sent, or a different preset message may also be sent, where the different preset message may be a message of the same type and different data size as the previous message, or a message of the same type and different data size as the previous message, and this is not particularly limited in the embodiment of the present application.

In an embodiment, in order to make the target features have a higher degree of distinction, when multiple matching is required, different preset message messages may be sent to the target mobile communication terminal, and the sending terminal of the uplink data corresponding to the matched target wireless network temporary identifier is determined as the target mobile communication terminal until the uniquely matched target wireless network temporary identifier is left in matching or the matching degree of a certain target wireless network temporary identifier is far higher than that of other target wireless network temporary identifiers, so that the subsequent business operations such as direction finding, positioning, management and control can be performed according to the uplink data of the target mobile communication terminal.

Optionally, after determining the information corresponding to the target wireless network temporary identifier as the information belonging to the target mobile communication terminal, the method for determining the mobile communication terminal information provided in the embodiment of the present application may further include the following steps:

step 280, based on the uplink signal strength corresponding to the target wireless network temporary identifier, performing service operation on the target mobile terminal, and generating a service operation result.

Specifically, after the information corresponding to the target wireless network temporary identifier is determined to belong to the information of the target mobile communication terminal, the uplink signal strength corresponding to the target wireless network temporary identifier may be obtained based on the information corresponding to the target wireless network temporary identifier, so as to perform service operations such as direction finding, positioning, management and control on the target mobile communication terminal according to the obtained uplink signal strength, and obtain a service operation result. The uplink signal strength corresponding to the target wireless network temporary identifier may refer to the signal strength of an uplink signal carrying the target wireless network temporary identifier, where the uplink signal includes an uplink signal sent by the target mobile communication terminal to the base station. Therefore, the embodiment of the application can perform subsequent business operations such as direction finding, positioning, management and control and the like according to the acquired RNTI and the uplink signal strength of the target mobile communication terminal, and meets the business operation requirements.

For example, when performing a direction-finding service operation, after determining the RNTI of the target mobile communication terminal by the device for determining the mobile communication terminal information, the DCI of the target mobile communication terminal may be determined according to the RNTI of the target mobile communication terminal, the DCI may indicate time-frequency information of a signal sent by the target mobile terminal to the base station, and the device for determining the mobile communication terminal information may perform direction-finding according to the time-frequency information as the direction-finding device to obtain a direction-finding operation result of the target mobile communication terminal.

In the actual processing, when multiple matching is required, the target mobile communication terminal needs to be kept in the connected state all the time, otherwise, the situation that the target mobile communication terminal continuously re-initiates access and the RNTI of the target mobile communication terminal changes all the time occurs, so that the RNTI with high matching degree cannot be found in the multiple matching process. Therefore, in order to enable the target mobile communication terminal to keep in the connected state, the time interval between the two messages received by the target user (i.e. the target mobile communication terminal) can be smaller than the threshold value by continuously sending the messages to the target mobile communication terminal.

In an optional embodiment, in order to make the time interval between the two message receptions of the target user not too long, an appropriate message type can be selected according to the local message transmission condition, so as to transmit the preset message to the target mobile communication terminal according to the selected message type. The message types in the embodiment of the present application may include, but are not limited to, a short message type, a multimedia message type, a telephone message type, and a Ping packet message type.

In actual processing, an air interface has a large amount of data all the time, and both non-target data and non-preset data are extremely large. In order to reduce the time consumption for decoding and matching and improve the matching success rate, a matching time window may be increased, and only the air interface downlink data in the matching time window is decoded and matched, where the matching time window may be composed of a matching start time and a matching end time. Further, the method for determining information of a mobile communication terminal provided in the embodiment of the present application may further include: after the preset message is sent to the target mobile communication terminal, determining the matching time corresponding to the preset message; and if the response message is not received within the matching time, updating a preset message and sending the updated preset message to the target mobile communication terminal. The matching time may be used to determine a matching time window corresponding to the preset message, and specifically may include a matching start time and a matching end time.

For example, in the case that the preset message is a multimedia message, after the device for determining the mobile communication terminal information sends the preset multimedia message, the device can record the current time as the matching start time when receiving the sending receipt responded by the base station, and can record the current time as the matching end time when receiving the receiving receipt responded by the base station, so that whether the response message corresponding to the preset message is received within the matching time can be determined based on the recorded matching start time and matching end time. If a response message corresponding to the preset message is received within the matching time, the target RNTI matched with the preset data characteristic can be confirmed by using the data characteristic after PDCCH decoding, so that the information corresponding to the target radio network temporary identifier is determined as the information belonging to the target mobile communication terminal according to the target RNTI, and the modulation and decoding difficulty of the target mobile communication terminal locked by characteristic matching is reduced; if the response message corresponding to the preset message is not received within the matching time, the preset message can be updated, the updated preset message can be sent to the target mobile communication terminal to trigger the target mobile communication terminal to reply the corresponding response message, so that the PDCCH data of the target mobile terminal presents preset data characteristics, and further, the sending terminal of the uplink signal information corresponding to the matched target RNTI can be determined as the target mobile communication terminal through multiple matching, so that the target mobile communication terminal can be subjected to business operations such as direction finding, positioning, management and control and the like on the basis of the uplink signal strength corresponding to the target radio network temporary identifier.

For another example, when the preset message is a Ping packet, the time for determining that the device of the mobile communication terminal information sends the Ping packet may be recorded as the matching start time, and the time for determining that the device of the mobile communication terminal information receives a response of the Ping packet may be recorded as the matching end time, so that the PDCCH decoding may be performed based on the downlink signal received within the matching time, thereby reducing the time consumed for decoding and matching and improving the matching success rate.

Further, the updating of the preset message in the embodiment of the present application may specifically include: and modifying the type of the preset message, and updating the preset message based on the modified type. And then, the updated preset message can be sent to the target mobile communication terminal to ensure that the target mobile communication terminal can receive the preset message, so that the PDCCH data of the target mobile communication terminal presents preset data characteristics, and then the data characteristics decoded by the PDCCH can be utilized for matching, so that the target mobile communication terminal can be found out based on the characteristic matching of the PDCCH.

Specifically, each preset message sent to the target mobile communication terminal may be subjected to feature extraction, and the extracted data features may be stored as first preset data features according to the feature table, so that the data features of the preset message sent at present may be subsequently queried according to the feature table, and then matching may be performed by using the data features of the preset message, so that when the data features of one downlink signal are matched with the data features of the preset message, the RNTI of the downlink signal is used as the target radio network temporary identifier, and thus the sending terminal of the uplink signal corresponding to the target radio network temporary identifier may be determined as the target mobile communication terminal, thereby achieving the purpose of searching the target mobile communication terminal.

To sum up, in the embodiment of the present application, a target mobile communication terminal sends a preset message to enable the target mobile communication terminal to receive a corresponding message and reply a corresponding response, so that PDCCH data of the target mobile communication terminal presents preset data characteristics, and after receiving a downlink signal, the downlink signal is decoded based on a PDCCH, so as to confirm a target RNTI matched with the preset data characteristics by using a radio network temporary identifier obtained after decoding and downlink control information corresponding to each radio network temporary identifier, and then determine information corresponding to the target radio network temporary identifier as information belonging to the target mobile communication terminal according to the matched target RNTI, that is, information of the target mobile communication terminal is locked by directly performing characteristic matching through data after decoding the PDCCH, thereby avoiding data decryption and data decryption in related technologies for locking the target mobile communication terminal, The problem of low efficiency of searching a target mobile communication terminal caused by decoding a Physical Downlink Shared Channel (PDSCH), and the problem of difficult high-order decoding can be bypassed because the PDCCH does not have high-order modulation of 16QAM and 64QAM, so that the decoding success rate is improved, the difficulty of modulation and decoding for locking a target by characteristic matching is reduced, the problems of high-order decoding and data decryption difficulty are solved, the cost of software development is saved, the requirement on the sensitivity of a front-end link is reduced, and the hardware cost is reduced.
