(4) The other server may be a server for determining whether the terminal accesses the pseudo base station, or may be a server for determining whether the terminal accesses an abnormal base station, or a server for determining the communication quality of the terminal, and the like, which is not limited herein. The other server may be a lower-level device of the core network device, or may be a peer-level device of the core network device, or may also be an upper-level device of the core network device, which is not limited herein.

As shown in fig. 1A, fig. 1B, or fig. 1C, a communication system provided in an embodiment of the present application includes at least one terminal (e.g., terminal 110), at least one access network device (e.g., access network device 120, access network device 130), at least one core network device (e.g., core network device 140), and at least one other server (e.g., other server 150). In the communication system, terminal 110 may send uplink data to access network device 120 or access network device 130, and access network device 120 or access network device 130 may send downlink data to terminal 110.

As shown in fig. 1A, the other server may serve as a subordinate device of the core network device, and may be connected to the access network device and the core network device. As such, core network device 140 may send downlink data (e.g., configuration information, etc.) to other server 150, and other server 150 may send the downlink data to access network device 120 or access network device 130, so that access network device 120 or access network device 130 sends the downlink data to terminal 110. And access network device 120 or access network device 130 may send the uplink data (e.g., the assistance information, etc.) from terminal 110 to other server 150, and other server 150 may send the uplink data to core network device 140.

As shown in fig. 1B, the other server may be a peer device of the core network device, and may be connected to the access network device and the core network device. As such, other server 150 or core network device 140 may send downlink data (e.g., configuration information, etc.) to access network device 120 or access network device 130, so that access network device 120 or access network device 130 sends the downlink data to terminal 110. And access network device 120 or access network device 130 may send the uplink data (e.g., assistance information, etc.) from terminal 110 to other servers 150 or core network device 140.

As shown in fig. 1C, the other server may be a higher-level device of the core network device, and may be connected to the core network device. As such, core network device 140 may receive downlink data from other server 150 (e.g., configuration information, etc.), and send the downlink data to access network device 120 or access network device 130, so that access network device 120 or access network device 130 sends the downlink data to terminal 110. And access network device 120 or access network device 130 may send uplink data (e.g., assistance information, etc.) from terminal 110 to core network device 140, and core network device 140 may send the uplink data to other server 150.

(5) The system information mainly includes a Master Information Block (MIB), a System Information Block (SIB), and a positioning system information block (posing SIB). The master information block includes the most important and frequently transmitted parameters that the terminal needs to obtain from the accessed cell, such as downlink bandwidth configuration, system frame number, and the like. The system information block comprises a plurality of different information blocks, 14 types have been defined in the standard protocol specification for NR: from system information block type1 to system information block type14, SIB1, SIB2, \ 8230 \ 8230;, SIB14 are abbreviated. SIBs other than SIB1 may also be referred to as Other System Information Blocks (OSIBs). By way of example with SIB1, SIB1 may include public land mobile network identification, tracking area number, cell identification, cell selection information, etc. The location system information block mainly includes location related parameters, such as base station location, etc.

In the following 5 scenarios: after the terminal is powered on, selects a cell to reside, reselects a cell, completes handover, enters a preset system from other systems (for example, in a 4G scenario, enters an LTE system from other Radio Access Technology (RAT) systems), and returns from loss coverage, the terminal may actively acquire system information. After the terminal acquires the system message in the above scenario, the terminal does not repeatedly read the system message, but only re-reads and updates the system message when any one of the following conditions is satisfied, where the condition includes that a change of the system message is indicated in the received paging message, that a public warning system (PWM) message broadcast is indicated in the received paging message, that a maximum validity period of the system message is exceeded (for example, 3 hours), and the like. The PWM may include an Earthquake and Tsunami Warning System (ETWS) or a Commercial Mobile Alert System (CMAS), among others.

Generally, in a normal communication scenario, an access network device broadcasts system information of a cell, a terminal searches signals of surrounding cells, measures signal quality of each cell, receives the system information of the cell, and selects a suitable cell for access. For example, when the terminal is in an idle state and performs cell reselection, the terminal measures the signal quality of neighboring cells around the terminal, and when the signal quality of a certain neighboring cell meets the cell reselection condition, the terminal reselects the cell. For another example, when the terminal is in a connected state, the terminal has currently accessed to a cell (referred to as a source cell) of a certain access network device (referred to as a source access network device), and the terminal may measure the signal quality of the source cell and the signal quality of a neighboring cell, generate a signal quality measurement report, and send the signal quality measurement report to the source access network device. When determining that the signal quality of a certain adjacent cell is better than that of the source cell, the source access network device triggers a switching process to control the terminal to access the adjacent cell with better signal quality.

(6) A pseudo base station (FBS), which is an access network device forged by an attacker, may be deployed in the vicinity of the terminal, or in the vicinity of the access network device. In this way, when the terminal measures the signal quality of the peripheral cell, the signal quality of the cell of the pseudo base station is also measured. For an idle terminal, if the signal quality of the pseudo base station is very good, the terminal may reselect to the cell of the pseudo base station. For a connected terminal, if the cell signal quality of the pseudo base station is better than that of the source cell, and the handover condition is satisfied, the source access network device may be triggered to initiate a handover procedure for the terminal, so that the terminal resides in the cell of the pseudo base station.

The pseudo base station may perform denial of service (DoS) attack on the terminal or a network corresponding to the terminal, or forge system information and the like, which may cause that the terminal and the access network device may not normally communicate. For example, suppose the pseudo base station is access network device 130 in fig. 1A and the non-pseudo base station is access network device 120 in fig. 1A. After the terminal 110 in fig. 1A accesses the access network device 130, the access network device 130 may initiate a DoS for the terminal 110 or a network corresponding to the terminal 110, or change system information, so that the terminal 110 and the access network device 120 cannot normally communicate. In this embodiment of the present application, the system information that the pseudo base station may change may include cell access related information, serving cell configuration parameters, user Access Control (UAC) parameters, tracking Area Update (TAU) parameters, PWM information, and the like, which is not limited herein.

The pseudo base station can also steal user data in the terminal (for example, steal user bank card information, identity card information, etc.), which brings security problem. In a new scenario of wireless communication, security problems caused by the pseudo base station are more serious. For example, after a terminal in the vertical media domain is attacked by a pseudo base station, a larger area of service paralysis or information leakage public security incident can be caused.

(7) The abnormal access network device may be an access network device having an abnormality in communication with the terminal. The abnormal access network device may include a pseudo base station and a device with a communication failure in the access network device, for example, a base station that frequently pages the terminal due to poor channel quality, or a base station that frequently does not page the target UE due to an identification (e.g., UE ID) storage error of the terminal, and the like.

(8) The normal access network device may be an access network device capable of implementing normal communication with the terminal. The normal access network device may be an access network device in a preset list, or an access network device that can receive the auxiliary information.

(9) The target device may include at least one access network device, at least one core network device, or at least one other server. The target device is used for sending configuration information to the terminal to acquire auxiliary information of the terminal, wherein the auxiliary information is used for determining whether abnormal access network devices exist. In this embodiment of the present application, the configuration information may be generated by the core network device or generated by another server, and the auxiliary information may be processed by the access network device or sent to the core network device or another server for processing, which is not limited herein.

It should be noted that the target device that sends the configuration information to the terminal and the target device that receives the auxiliary information from the terminal may be the same target device or different target devices. When the target device is an access network device, the configuration information may be sent to the access network device from another server or a core network device, and then sent to the terminal by the access network device. When the target device is a core network device, the configuration information may be sent to the access network device by the core network device first, and then sent to the terminal by the access network device; or the configuration information can be acquired by the core network device from other servers, then sent to the access network device, and sent to the terminal by the access network device; or the configuration information may be sent to other servers by the core network device first, then sent to the access network device by other servers, and sent to the terminal by the access network device. When the target device is other server, the configuration information can be sent to the access network device by other server first, and then sent to the terminal by the access network device; or the configuration information can be acquired from the core network equipment by other servers, then sent to the access network equipment, and sent to the terminal by the access network equipment; or the configuration information may be sent to the core network device by another server, then sent to the access network device by the core network device, and sent to the terminal by the access network device.

In this embodiment of the present application, when a target device that sends configuration information is different from a target device that receives configuration information, other target devices may be used to describe different target devices. For example, a first device and a second device described later, where the second device may be another target device when the first device is taken as the target device.

(10) Configuration information for instructing the terminal to perform a specified operation. In the embodiment of the present application, the configuration information may specifically include a first indication for instructing the terminal to record paging record information and/or a second indication for instructing to record system information update record information, and the like. The paging record information and the system information update record information may both be recorded in the form of logs, for example, files with log suffixes, or may be recorded in the form of tables, which is not limited herein.

When the terminal has the downlink data, the core network equipment informs the access network equipment to carry out paging, and the access network equipment sends a paging message to the terminal. In this way, the terminal may listen to the paging message at its paging occasion (paging occasion), and determine the paging message as the terminal when the paging message includes the identifier of the terminal.

The identifier of the terminal (e.g., UE ID) is not limited in this application, and when the 5G system performs paging, the identifier of the terminal in the paging message may be a 5G service temporary mobile subscriber identity (S-TMSI) or the like. When the 4G system performs paging, the identifier of the terminal in the paging message may be an inactive radio network temporary identifier (I-RNTI).

If the access network equipment accessed by the terminal is abnormal access network equipment, the terminal is difficult to monitor the paging message sent by the normal access network equipment in the paging occasion. If the access network device accessed by the terminal is a pseudo base station, the paging message monitored by the terminal may be a paging message forged by the pseudo base station. Based on this, in this embodiment of the present application, configuration information including the first indication may be sent to the terminal, so that the terminal records information of the paging message according to the configuration information to obtain paging record information, and sends the paging record information to the access network device. Therefore, the target device can determine whether the terminal receives the paging message, whether the paging message changes or is abnormal based on the paging record information, and the like, so as to determine whether the paging event with abnormal frequency or sparsity or the paging event with paging failure exists, and improve the accuracy of determining whether the area where the terminal is located has the abnormal access network device. In addition, the paging message may be triggered by system information update, and the terminal may further obtain system information update record information according to the configuration information including the second indication, and then send the system information update record information to the access network device. As such, the target device may determine whether there is an abnormal access network device based on whether a paging message indicating system information update is received, whether system information is updated and whether updated system information is abnormal, whether normal communication with the access network device is possible after update, and the like.

(11) The system information update recording information is used for recording relevant information of the terminal receiving the paging message for indicating the system information update, and may include time information of the terminal monitoring the first paging message. The first paging message is used to instruct the terminal to perform system information update, that is, the first paging message is a paging message triggered by the system information update in the paging message. The time information when the terminal monitors the first paging message may be a reception time when the terminal monitors the first paging message, or a time difference between the reception time and a time when the configuration information is received, or a time difference between the reception time and an initial time of the first paging occasion, and the like. The system information update record information may further include the number of times the terminal has listened to the first paging message. For example, the system information update record information may be recorded as the first time the terminal hears the first paging message, time 1; the second time the terminal hears the first paging message, time 2, etc.

It can be understood that if it is determined that the access network device a has sent the first paging message to the terminal a at time a according to the system information update record information reported by the terminal B, but it is determined that the time information that does not monitor the first paging message includes time a according to the system information update record reported by the terminal a, it indicates that the terminal a has not received the first paging message at time a, and that there is an abnormality in communication between the terminal a and the access network device a. And the number of times that the terminal does not hear the first paging message can be determined according to the time information and/or the number of times that the terminal does not hear the first paging message. If the number is greater than the threshold value A, it may indicate that there is an abnormality in the communication between the terminal A and the access network device. The threshold a may be determined according to a time duration from the beginning of the paging occasion to the end of the paging occasion, or may be determined according to a paging frequency of the access network device, which is not limited herein. By recording the time information that the terminal does not monitor the first paging message, whether the terminal receives the abnormal first paging message or does not monitor the first paging message which should be received can be determined, so that the accuracy of determining whether the abnormal access network equipment exists in the area where the terminal is located can be improved.

The system information update record information may further include update information of the first paging message, and the update information may include an SIB for indicating system information update in the first paging message, for example, first time, time 1, update SIB1; the second time, time 2, update SIB2. The update information may alternatively include a tag value (ValueTag) field for judging that the system information is updated. The field can be a systemlnfovaluetag field in SIB1, the value range is 0-31, the field is increased by 1 when the network side executes the system information change process for 1 time, and the UE side judges whether the system information change process needs to be executed according to whether the value changes. For example, first time, time 1, valueTag1; second time, time 2, valueTag 2. The update information may also include system information in the first paging message indicating updating in the SIB, e.g., cell access related information, serving cell configuration parameters, UAC parameters, TAU parameters, PWM information, etc.

It can be understood that, if it is determined that the access network device a sends the first paging message to the terminal a at the time B according to the system information update record information reported by the terminal B, and it is determined that the terminal a monitors the first paging message at the time B according to the system information update record reported by the terminal a, it indicates that the terminal a receives the first paging message at the time B, and the update information in the first paging message reported by the terminal B and the update information in the first paging message reported by the terminal a may be compared to determine whether the update information changes. And when the update information is determined to be changed, determining that the terminal A or the terminal B is accessed to the abnormal access network equipment. By recording the updating information of the first paging message, whether the first paging message received by the terminal is a forged system message can be determined, and the accuracy of determining whether the area where the terminal is located has abnormal access network equipment can be improved.

The system information update record information may further include system information abnormal update record information, and the like, which is not limited herein. The system information abnormal update recording information is used for recording relevant information of terminal abnormal update system information, such as time information and tracking area for frequently updating TAU parameters. It is understood that, within a certain period (e.g., the first duration), if the number of updates of the TAU parameter is greater (e.g., greater than the first threshold), it indicates that the TAU parameter is updated frequently. If the updated tracking area list is the same, it indicates that the tracking area where the terminal is located is unchanged, so that it can be determined that the communication between the terminal and the access network device in the tracking area is abnormal, and the accuracy of determining whether the area where the terminal is located has the abnormal access network device can be improved by recording the abnormal recording information of the TAU parameter. The first duration and the first threshold are not limited in this application. The first duration may be from the time when the terminal receives the configuration indication to the time when the terminal reports the auxiliary information (or the first message, etc.). The first duration may either be carried by the target device within the configuration information or set by the terminal itself. The first duration may be an absolute time interval, such as 8:00 to 9:00, or set as a length of absolute time calculated from the time of the first TAU update, such as a length of 1 hour after the first TAU update. The first threshold may be a designated value, or may be set using information such as target device configuration or terminal update record according to terminal type or history TAU.

The system information abnormal update record information may further include abnormal record information of receiving the paging message after updating the paging parameter, that is, related information of communication abnormality occurring after updating the paging parameter. It can be understood that if the terminal does not monitor the first paging message within a certain time period (for example, the second time period) after updating the paging parameter, it may indicate that the terminal is disconnected from the access network device, or indicate that the access network device to which the terminal is accessed is an abnormal access network device, and by recording the abnormal record information of the received paging message after updating the paging parameter, the accuracy of determining whether the area where the terminal is located has the abnormal access network device may be improved. The second time duration is not limited, and the second time duration may be configured for the target device or set by the terminal according to the longest time history of the terminal, the time when the terminal receives the paging after updating the paging parameter, and the like.

The system information abnormal update record information may also include abnormal record information with limited access after updating the system information, and the like, which is not limited herein. The limited terminal access means that the terminal has Radio Link Failure (RLF), handover failure (HOF), integrity check failure (integrity check failure), radio Resource Control (RRC) reconfiguration failure, and other events, and cannot communicate with the access network device. The access-limited abnormal record information after updating the system information may include the number of times of access limitation of each time of the terminal, time information, and the like. It can be understood that if the number of times that the terminal is accessed to the access network is limited is large (for example, the second threshold), it indicates that the terminal cannot perform normal communication with the access network device, or indicates that the access network device accessed by the terminal is an abnormal base station, and the accuracy of determining whether the access network device in which the terminal is located is abnormal or not can be improved by recording the abnormal record information that is accessed to the limited after updating the system information. The second threshold is not limited in the present application, and the second threshold may be that the target device configuration information is sent to the terminal, or the terminal performs setting according to the terminal type or the access times of the historical time, and the like.

It can be understood that, if the system information update record information reported by the terminal a includes a system information abnormal update record, it indicates that the terminal a determines that an abnormal system update event occurs. The system information updating record information reported by other terminals can be compared with the system information abnormal updating record reported by the terminal A, so as to further determine whether the terminal A has an abnormal system updating event. By recording the system information abnormal record, the efficiency of determining whether the area where the terminal is located has abnormal access network equipment can be improved, and the accuracy of determining whether the terminal has abnormal system updating events can be improved conveniently.

The above-described various pieces of system information update record information may be comprehensively used to determine whether an abnormal access network device exists in the area where the terminal is located, for example, if the system information update record information reported by other terminals can determine that the terminal a updates the SIB1 at the location a and at the time C. But after the terminal a updates SIB1, if the paging message is not monitored, it is determined that the access network device near location a has an abnormality.

(12) The paging record information is used to record the related information of the paging message received by the terminal, and may include system information update record information, which may refer to the foregoing description and is not described herein again. The paging record information may further include time information that the terminal does not listen to the paging message, and may be a difference or a time range between a time when the terminal first listens to the paging message and an initial time of the paging occasion, for example, from 8:00, and listens for the paging message every 10 minutes, and the time when the terminal first listens for the paging message is 8. The time information that the terminal does not listen to the paging message may also be a difference value or a time range between each time the terminal does not listen to the paging message and the last time the terminal listens to the paging message, for example, (8. The time information that the terminal does not listen to the paging message may also be a difference between a listening period (a period from the beginning of the first paging occasion to the end of the last paging occasion) and a time duration of the paging occasion that listens to the paging message, and the like, which is not limited herein.

The paging record information may further include the number of times of paging occasions when the terminal does not monitor the paging message, and in combination with the time information when the terminal does not monitor the paging message, the paging record information may be recorded as (8; second time (8, 50, 9). The number of times may also represent the number of times that the paging message is not monitored in the monitoring period, which may be obtained by the difference between the number of all paging occasions and the number of paging occasions that the paging message is monitored.

It can be understood that if it is determined that the access network device a sends the second paging message to the terminal a at the time D according to the paging record information reported by the terminal B, and the time information that the terminal a does not monitor the paging message includes the time D, it may indicate that there is an abnormality in the communication between the terminal a and the access network device a. And the number of times that the terminal a does not listen to the paging message may be determined based on the time information and/or the number of times that the terminal does not listen to the paging message. If the number is greater than the threshold value A, it may indicate that there is an abnormality in the communication between the terminal A and the access network device. The threshold a may be determined according to a time length from the beginning of the paging occasion to the end of the paging occasion, or according to a paging frequency of the access network device, and the like, which is not limited herein. By recording the time information that the terminal does not monitor the paging message, whether the terminal does not monitor the paging message is the paging message which should be received can be determined, and the accuracy rate of determining whether the area where the terminal is located has abnormal access network equipment can be improved conveniently.

The paging record information may further include time information when the terminal does not hear the second paging message. The second paging message is used for paging the terminal, and may be understood as that the second paging message includes an identifier of the terminal, and the identifier of the terminal may refer to the foregoing description, and is not described herein again. Since the system information update may trigger the sending of the paging message, the second paging message includes the first paging message. The time information when the terminal does not hear the second paging message may be a difference or a time range between a time when the terminal first hears the second paging message and an initial time of the paging occasion, for example, from 8:00, monitoring the paging message once every 10 minutes, monitoring the second paging message for the fourth time, and recording the time information when the terminal does not monitor the second paging message as the identification information of the terminal: 0. The time information that the terminal did not listen to the second paging message may also be a difference or a time range between each time the terminal did not listen to the second paging message and the last time the terminal listened to the second paging message, e.g., (8; (8, 50, 9. The terminal may not monitor the time information of the second paging message, and may also monitor a difference between a period and a duration of monitoring the paging occasion of the second paging message, which is not limited herein.

The paging record information may further include the number of times that the terminal did not hear the second paging message, and in combination with the time information that the terminal did not hear the second paging message, the paging record information may be recorded as (8; second time (8. The number of times may also indicate the number of times the second paging message is not monitored during the listening period, which may be obtained by a difference between the number of all paging occasions and the number of paging occasions at which the second paging message is monitored.

It can be understood that if it is determined that the access network device a sends the second paging message to the terminal a at the time D according to the paging record information reported by the terminal B, and the time information that the terminal a does not monitor the second paging message includes the time D, it may indicate that there is an abnormality in the communication between the terminal a and the access network device a. And the number of times the terminal did not hear the second paging message may be determined based on the time information and/or the number of times the terminal did not hear the second paging message. If the number is greater than the threshold B, it may indicate that there is an anomaly in the communication between the terminal and the access network device. The threshold B may be determined as described with reference to the threshold a, and the threshold B may be less than or equal to the threshold a. By recording the time information that the terminal does not monitor the second paging message, whether the terminal receives the abnormal second paging message or does not monitor the second paging message which should be received can be determined, and the accuracy of determining whether the area where the terminal is located has the abnormal access network equipment can be improved conveniently.

The paging record information may further include time information and/or times that the terminal listens to the second paging message, and may refer to descriptions of the time information and/or times that the terminal listens to the first paging message, which are not described herein again. If it is determined that the access network device a sends the second paging message to the terminal a at the time D according to the paging record information reported by the terminal B, and the time D is not included in the time information of monitoring the second paging message according to the terminal a, it may indicate that there is an abnormality in the communication between the terminal a and the access network device a. If it is determined that the access network device B does not send the second paging message to the terminal a at the time E according to the paging record information reported by the terminal B, and the second paging message from the access network device B is monitored at the time E according to the terminal a, it may indicate that there is an abnormality in the communication between the terminal a and the access network device B, or that there is an abnormality in the communication between the terminal B and the access network device B. And determining the number of the second paging messages monitored by the terminal based on the time information and/or the number of times that the terminal monitors the second paging messages, wherein if the number is greater than a threshold value C or less than a threshold value D, the number may indicate that the second paging messages received by the terminal are abnormal, and it may be determined that the communication between the terminal and the access network device is abnormal. The threshold C and the threshold D may be determined as described with reference to the threshold a, the threshold C is greater than the threshold D, and the threshold C may be greater than or equal to the threshold B. By recording the time information when the terminal monitors the second paging message, whether the terminal receives the abnormal second paging message or does not monitor the second paging message which should be received can be determined, and the accuracy of determining whether the abnormal access network equipment exists in the area where the terminal is located can be improved.

The paging record information may further include location information of the terminal, for example, an address location such as a geographical location of the terminal obtained by Global Navigation Satellite System (GNSS) positioning. Or may include a moving path of the terminal and a measurement report acquired by the terminal, etc. Or may include an area identifier of the terminal, for example, an identifier of a cell (cell), an identifier of a Location Area (LA), an identifier of a routing area (routing area), an identifier of a tracking area (tracking area), etc., or may include identification information of the terminal and identification information of a Public Land Mobile Network (PLMN), etc., which is not limited herein. It is to be understood that, based on the above area identifier, the location of the terminal when recording the auxiliary information may be determined, so that whether an abnormal access network device exists in the area scope may be determined based on the paging message in the area scope corresponding to the location or the location.

The paging record information may further include a recording time of the paging record information, and the like, which is not limited herein. The recording time may include an actual time for recording the paging record information, or may be a difference between the actual time and the receiving configuration information, and the like, which is not limited herein.

The above-described paging record information may be comprehensively used to determine whether an abnormal access network device exists in the area where the terminal is located, for example, if it is determined that the terminal a monitors the first paging message of the access network device a at the location a and the time E according to the paging record information reported by the terminal, the terminal a monitors the first paging message of the access network device B at the location B and the time F. If the access network device a and the access network device B belong to the same tracking area, the paging record information reported by other terminals received by the access network device B may be used. If it is determined that the access network equipment A frequently pages the terminal at the time when paging is not required according to the paging record information reported by other terminals, it can be determined that the access network equipment near the position A is abnormal. In the embodiment of the present application, the configuration information may further include effective area information, which may be understood as a notification area of the configuration information (e.g., a notification area of a paging message or a system information update), or may be understood as an area where data is recorded. Therefore, the communication quality and the communication safety of the area corresponding to the effective area information can be improved by reporting the auxiliary information corresponding to the effective area information. The valid area information may include PLMN information, registration area (registering area) information, an identifier of the terminal, and the like. The registering area information may include an identifier of a cell (cell), an identifier of a Location Area (LA), an identifier of a routing area (routing area), an identifier of a tracking area (tracking area), and the like, which is not limited herein.

When the terminal supports a Minimization of Drive Test (MDT) technique, the configuration information may be added in the MDT configuration information. The MDT technology is a technology for a communication system to automatically acquire and analyze a terminal measurement report containing location information, and is used to reduce the workload of manual drive test to the maximum extent and can detect and optimize problems and faults in a wireless network. When the configuration information is added to the MDT configuration information, the location information in the existing measurement report can be utilized, which can improve the information acquisition efficiency and realize the same function as the drive test. The reporting type of the MDT can be classified into the following four categories, wherein:

1) The MDT (Immediate MDT) reported immediately is only applicable to the terminal in the active state, i.e. the measurement and reporting are performed in the active state. The reported content comprises wireless network measurement information and position information measured by the terminal as much as possible.

2) The Logged MDT (Logged MDT) refers to a measurement data collection method in which a terminal measures in an idle state and obtains a measurement result, and then temporarily stores the measurement result in a memory of the terminal in a log file format, and reports the measurement result after entering an active state next time. What content the Logged MDT will report specifically depends on the terminal, and the network side cannot control.

3) MDT (RLF Report MDT) reported when a radio link fails refers to a measurement data collection method in which a terminal measures a serving cell, an adjacent cell, and a location when the radio link fails, and a measurement result is temporarily stored in a memory of the terminal in a log file format and reported after the terminal re-enters an active state after a successful re-establishment or a call drop.

4) MDT (RCEF Report MDT) reported when RRC connection establishment fails refers to a measurement data collection method in which a terminal measures a serving cell, a neighboring cell, and a location when RRC connection establishment fails, a measurement result is temporarily stored in a memory of the terminal in a format of a log file, and the terminal reports the measurement data after being successfully re-accessed into an active state.

The present application is illustrated by a Logged MDT, please refer to fig. 2, and fig. 2 is a flowchart of a communication method provided in the prior art. The method comprises core network equipment, access network equipment 1, \8230 \ 8230;, access network equipment n and a terminal, wherein n is greater than or equal to 2. The method comprises the following steps S201 to S206, wherein:

s201: and the core network equipment sends the MDT configuration information to the access network equipment.

S202: and the access network equipment sends the MDT configuration information to the terminal.

S203: and the terminal acquires the measurement result according to the MDT configuration information and stores the measurement result in a log.

S204: the terminal sends an available indication of the measurement results to the access network device.

S205: and the access network equipment sends a response message to the terminal.

S206: and the terminal sends the measurement result to the access network equipment.

The MDT configuration information is used to instruct the terminal to perform drive test, and the type of the event to be recorded and related parameters, such as the duration of not receiving the paging message, the time threshold, and other information. Available indicators (available indicators) are used for indicating the measurement result to be reported by the terminal, and the measurement result is a Logged MDT type measurement result, can be described by using 1bit, and can be carried in information in the RRC establishment process, for example, in message 5 (Msg 5) for transmission. The response message is used to instruct the terminal to upload the measurement results in the available indication. It can be understood that after the access network device sends the MDT configuration information from the core network device to the terminal, the terminal may perform a drive test in an idle state according to the MDT configuration information, obtain a measurement result, and store the measurement result in a log. And then, the terminal sends an available indication to the access network equipment, and after receiving a response message sent by the access network equipment, if the terminal is in an activated state, the terminal sends a measurement result to the access network equipment so that the access network equipment or the core network equipment can acquire the drive test information of the area where the terminal is located.

It should be noted that the access network device in step S201, the access network device in step S205, and the access network device in step S206 may be any one of access network devices 1, \8230;, and n. The access network device in step S201 and the access network device in step S205 may be the same or different. The access network device in step S205 is the same as the access network device in step S206.

In one possible example, the paging record information includes at least one of: the terminal does not monitor the time information of the paging message; the number of times that the terminal does not monitor the paging occasions of the paging messages; the terminal does not monitor the time information of a second paging message, and the second paging message is used for paging the terminal; the terminal monitors the time information of the second paging message; the terminal monitors the times of the second paging message; the system information updates the record information; location information of the terminal; or the recording time of the paging record information. It can be understood that whether abnormal frequent or sparse paging events or paging events with paging failure exist can be determined by recording the paging record information, which is convenient for improving the accuracy of determining whether abnormal access network equipment exists in the area where the terminal is located.

It should be noted that, if the other server is a lower-level device or a peer device of the core network device, and the configuration information may be generated by the other server or the core network device, step S301 further includes that the other server or the core network device sends the configuration information to the first device. If the other server is a superior device of the core network device, the configuration information may be generated by the other server, and the other server sends the configuration information to the core network device before step S301; and the core network equipment sends the configuration information to the access network equipment.

Therefore, the target device on the network side can acquire the auxiliary information to determine the communication information of the terminal, so that the communication quality and the safety of the communication system are improved.

In a possible example, before step S303, the method may further include: the terminal sends a first message to the second equipment; the access network equipment sends a response message to the terminal.

The first message is used to indicate availability of the auxiliary information, and may refer to the description of the available indication in step S204, and the response message may refer to the description in step S205, which is not described herein again.

It is to be appreciated that after the terminal acquires the assistance information, a first message can be sent to the access network device to indicate that the assistance information is available, and the access network device can determine whether to receive the assistance information based on the first message. If yes, sending a response message to the terminal so that the terminal reports the auxiliary information. Therefore, the accuracy rate of reporting the auxiliary information can be improved.

In one possible example, after step S303, the method may further include: the second equipment determines whether the area corresponding to the auxiliary information has abnormal access network equipment or not according to the auxiliary information and the reference information; or the second device sends the auxiliary information to the core network device or other servers, so that the core network device or other servers determine whether the area corresponding to the auxiliary information has abnormal access network devices according to the auxiliary information and the reference information.

It can be understood that, when the area corresponding to the reference information and the area corresponding to the auxiliary information belong to the same tracking area, the paging messages received by the terminals in the tracking area are the same. Therefore, the second device may compare the auxiliary information with the reference information to determine whether different information is an abnormal paging message or abnormal log information of an abnormal system information update event, so as to determine whether an abnormal access network device exists in an area corresponding to the auxiliary information. After the access network device sends the auxiliary information from the terminal to the core network device or other servers, the core network device and other servers can obtain more other auxiliary information sent by other terminals, so that the accuracy of determining the abnormal access network device can be further improved.
