The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.

The present disclosure provides a communication method capable of acquiring information of a terminal accessed by a user, and some embodiments of the method of the present disclosure are described below with reference to fig. 1.
Fig. 1 is a flow chart of some embodiments of the disclosed communication method. As shown in fig. 1, the method of this embodiment includes: step S102 to step S108.
In step S102, signaling messages of the S11 interface between the MME and the SGW are collected.
The interactive message in the S11 interface may be acquired, and the protocol type and the message type of the message may be identified by a DPI (deep packet inspection) technique. The signaling message of the S11 interface includes, for example: create Session Request message (Create Session Request) in GTP (GPRS Tunneling Protocol).
In step S104, the type information of the terminal is parsed from the signaling message of the S11 interface, and the NB-IoT terminal is identified.
The signaling message of the S11 interface may carry the type information of the terminal. In some embodiments, the type information of the terminal may be carried in the create session request message. The Type of the terminal may be determined by parsing a value of a radio access technology Type (RAT Type) field in the create session request message. The value of the RAT Type field in the create session request message may be determined by the MME according to a Tracking Area (TA) of the terminal that the terminal is an NB-IoT Type terminal, and then a value corresponding to the NB-IoT Type is added to the create session request message.
In step S106, the identification information of the NB-IoT terminal is acquired from the signaling message of the S11 interface.
The identification information of the NB-IoT terminal includes, for example, at least one of number information and location information of the NB-IoT terminal. The Number information of the terminal is, for example, IMSI (Mobile Subscriber identity Number), MSISDN (Mobile station International ISDN Number), or the like. The Location information is obtained, for example, by creating a User Location Info field in the session request message.
In step S108, the sensing data of the NB-IoT terminal is searched according to the identification information of the NB-IoT terminal, and the sensing data of the NB-IoT terminal and the type information of the NB-IoT terminal are associated, so as to analyze the sensing data corresponding to the NB-IoT type terminal.
In some embodiments, the acquired number information and position information of the NB-IoT terminal are compared with the number information and position information of the terminal corresponding to the sensing data to determine the sensing data of the NB-IoT terminal. Through double matching of the number information and the position information, the sensing data of the NB-IoT terminal can be accurately determined. The sensing data of the terminal is, for example, the service condition of the KQI (key quality indicator) sensing terminal, such as application, attachment success rate, traffic information, delay information, and transmission rate information corresponding to the terminal.
In the method of the above embodiment, the NB-IoT terminal is identified by acquiring the signaling message of the S11 interface between the MME and the SGW, and analyzing the type information of the terminal. And further acquiring the identification information of the NB-IoT terminal from the signaling message, and acquiring the perception data of the NB-IoT terminal through the identification information of the NB-IoT terminal so as to analyze the perception data corresponding to the NB-IoT type terminal. The method and the device do not change the existing signaling interaction process, can accurately identify the NB-IoT type terminal by acquiring the interface signaling, further synchronize the acquired type information of the NB-IoT terminal with the perception data in real time, improve the accuracy of user perception, and improve the operation support capacity and efficiency.
Further embodiments of the communication method of the present disclosure are described below in conjunction with fig. 2.
Fig. 2 is a flow chart of further embodiments of the communication method of the present disclosure. As shown in fig. 2, the method of this embodiment includes: step S202 to step S210.
In step S202, signaling messages of the S11 interface between the MME and the SGW are collected.
In step S204, the type information of the terminal is parsed from the signaling message of the S11 interface, and the NB-IoT terminal is identified.
In step S206, the identification information of the NB-IoT terminal is acquired from the signaling message of the S11 interface.
In step S208, the sensing data of the NB-IoT terminal is searched according to the identification information of the NB-IoT terminal, and the sensing data of the NB-IoT terminal and the type information of the NB-IoT terminal are associated.
In step S210, the sensing data corresponding to the NB-IoT type terminal is matched with the NB-IoT terminal service quality discrimination model to determine whether the NB-IoT type terminal has a failure.
Different quality of service discrimination models may be set for different types of terminals. The NB-IoT terminal service quality judgment model comprises NB-IoT terminal service quality judgment conditions and judgment logic. For example, various terminal quality levels (for example, high level, middle level and low level are set in the NB-IoT terminal service quality discrimination model), different terminal quality levels correspond to different NB-IoT terminal perception data thresholds, and by comparing the NB-IoT terminal perception data with the corresponding NB-IoT terminal perception data thresholds, the terminal quality level corresponding to the NB-IoT terminal can be determined. NB-IoT terminal-aware data thresholds include, for example: at least one of an attach success rate threshold, a traffic threshold, a delay threshold, and a transmission rate threshold.
Further, different NB-IoT terminal perception data thresholds can be set in the NB-IoT terminal service quality discrimination model according to different application types and terminal service quality levels corresponding to the NB-IoT terminals. For example, for the same terminal quality of service level, the NB-IoT terminal-aware data threshold corresponding to the application with the higher priority is higher than the NB-IoT terminal-aware data threshold corresponding to the application with the lower priority. For example, for the same terminal quality of service level, the NB-IoT terminal traffic threshold for a high priority application is 100M, while the NB-IoT terminal traffic threshold for a low priority application is 80M.
In some embodiments, the sensing data corresponding to the NB-IoT type terminal within the preset time is matched with the NB-IoT terminal service quality discrimination model, and the number of times that the NB-IoT type terminal service quality is lower than the preset terminal service quality within the preset time is determined. And under the condition that the times that the service quality of the NB-IoT type terminal is lower than the preset terminal service quality grade within the preset time exceeds the time threshold, determining whether the NB-IoT type terminal fails or not according to the service quality of the cell to which the NB-IoT type terminal belongs.
For example, the attach success rate, the traffic information, the delay information, and the transmission rate information corresponding to the NB-IoT type terminal within the preset time are respectively compared with an attach success rate threshold, a traffic threshold, a delay threshold, a transmission rate threshold, and the like, to determine whether the service quality of the NB-IoT type terminal is lower than the preset terminal service quality. The preset terminal service quality may be represented by a terminal service quality class, for example, the preset terminal service quality is a low class, and when the sensing parameter of the NB-IoT type terminal is lower than the sensing parameter threshold corresponding to the low class, it is determined that the NB-IoT type terminal service quality is lower than the preset terminal service quality. Or, the preset terminal service quality is directly represented by a corresponding perception parameter threshold value.
Further, different preset terminal service qualities can be different for different application corresponding NB-IoT type terminals. For example, the preset terminal service quality corresponding to the application with high priority is higher than the preset terminal service quality corresponding to the application with low priority. In the case that the number of times that the service quality of the NB-IoT type terminal is lower than the preset terminal service quality within the preset time exceeds the number threshold, it is necessary to further refer to the service quality of the cell to which the terminal belongs to determine whether the terminal has a failure.
The quality of service of a cell may be determined based on the quality of service of all terminals in the cell. And searching the cell to which the NB-IoT type terminal belongs according to the NB-IoT type terminal, further searching all NB-IoT type terminals under the cell after the cell is determined, and acquiring the perception data of all NB-IoT type terminals. For example, the quality of service of a cell may be determined according to the terminal service class of the NB-IoT type terminals within the cell. Further, the service quality of the cell may be determined according to the number of NB-IoT terminals belonging to different terminal service classes. For example, the maximum number of NB-IoT terminals belonging to a high rank indicates that the service quality of the cell is high. Or setting different terminal service level scores, averaging the terminal service level scores of all NB-IoT terminals, further comparing the average value with a corresponding threshold value, and determining whether the service quality of the cell is lower than the preset cell service quality.
Alternatively, the quality of service of a cell may be determined by weighting and averaging the perceptual data of all NB-IoT type terminals within the cell. The weights corresponding to the perception data of different NB-IoT terminals may be set according to the priority of the application corresponding to the terminal. The higher the priority of the application, the smaller the weighting factor. And respectively weighting and averaging the different types of sensing data. And further obtaining the weighted average value of the different types of sensing data corresponding to the cell, comparing the weighted average value with a preset sensing data threshold value, and determining whether the service quality of the cell is lower than the service quality of a preset cell.
Or counting the number of NB-IoT terminals of which the times of the service quality in the cell is lower than the service quality of the preset terminal exceeds the time threshold, and determining whether the service quality of the cell is lower than the service quality of the preset cell. If the number of the NB-IoT terminals with the service quality lower than the preset terminal service quality exceeds the number threshold (for example, the number of the NB-IoT terminals with the service quality lower than the preset terminal service quality exceeds 5 times exceeds 20), the service quality of the cell is lower than the preset cell service quality, otherwise, the service quality of the cell is not lower than the preset cell service quality.
And under the condition that the service quality of the cell to which the NB-IoT type terminal belongs is lower than the preset cell service quality, determining that the NB-IoT type terminal is normal and the cell to which the NB-IoT type terminal belongs is failed. And under the condition that the service quality of the cell to which the NB-IoT type terminal belongs is higher than the preset cell service quality, determining that the NB-IoT type terminal fails.
In case of failure of an NB-IoT type terminal, the NB-IoT type terminal needs to be overhauled. Under the condition that the cell to which the NB-IoT type terminal belongs has a fault, the fault reason of the fault cell needs to be judged, and corresponding measures need to be taken. For example, the current load condition of the faulty cell is determined, and when the load exceeds the load threshold, it is determined that the resource of the faulty cell is insufficient, and when the load exceeds the load threshold, the faulty cell may be repaired to determine the cause of the fault.
Because the situation that a command is issued to a large number of NB-IoT terminals or a report message of the large number of NB-IoT terminals is received at the same time may exist in the narrowband IoT, the situation that the cell is judged to be a fault cell due to insufficient cell resources may occur. For the situation, according to the application priority and the preset number corresponding to the NB-IoT type terminals, the NB-IoT terminals in the faulty cell may divide different batches, issue messages to the NB-IoT terminals according to the batches, or notify the NB-IoT terminals to report messages according to the batches. And the higher the application priority is, the NB-IoT terminals are divided into more preferred batches to receive the issued messages or report the messages.
If there are multiple faulty cells, the processing priority can be determined according to the service quality of the faulty cell. The service quality of the cell may be determined according to the method of the foregoing embodiment, and the better the service quality of the cell is, the lower the processing priority is.
According to the method of the embodiment, whether the NB-IoT terminal or the affiliated cell fails or not can be determined through the perception data of the NB-IoT terminal. Different handling methods can be adopted based on different faults. The method and the device realize real-time acquisition and real-time judgment and processing of the sensing data of the NB-IoT terminal, and improve operation support capability and efficiency.
