Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a detection method, apparatus, and device. Background Technology

[0002] During the frequency change process for Narrow Band Internet of Things (NB-IoT), some areas of the existing network have been changed to the new frequency EARFCN. new However, the surrounding area has not yet undergone frequency refarming and remains the old frequency EARFCN. legacy In this situation, terminals in refarmed areas may be unable to access the network.

[0003] (1) Before frequency refarming, the terminal resides on the old frequency point EARFCN. legacy In certain areas, after frequency refarming, terminals will prioritize camping on historical frequency cells (i.e., old frequency EARFCNs). legacy However, it may be far from older frequency cells, resulting in poor network signal quality (such as Reference Signal Receiving Power (RSRP) and Signal to Interference plus Noise Ratio (SINR)). Please refer to [references for other information]. Figure 1 Example.

[0004] (2) Most existing NB-IoT terminals are metering terminals. In order to save terminal power consumption, the terminal will shut down within a certain period of time (e.g., 3 minutes) after the data is reported. If the terminal does not start reselection in time, it will be unable to reselect to a cell with good network signal, which may cause the terminal to be unable to access the network.

[0005] To address the issue of some terminals being unable to access the network after frequency refarming in certain areas, it is necessary to use the new frequency point EARFCN. new Adding old frequency points that have not been refarmed (EARFCN) legacy The neighbor cell list is generated, and the SIB2-NB and SIB3-NB / SIB5-NB are sent out at the same time and with the same period, so that the terminal can reselect to a cell with a good network signal in a timely manner.

[0006] Existing solutions require professional testers to conduct tests and capture logs in areas where access is unavailable. These logs then need to be sent back to R&D for signaling checks, and finally, feedback must be provided to the user regarding the specific reasons for the access failure, the effectiveness of network configurations, etc. This process takes a considerable amount of time. For ordinary users (non-professionals), without understanding the detailed communication process of NB-IoT, it is difficult to detect and analyze the current problem. Summary of the Invention

[0070] In one embodiment of this application, the detection result further includes: the reason why the terminal can access the first area, wherein the reason is that there is no problem with access after frequency refarming.

[0071] In the embodiments of this application, the detection device receives system messages sent by the network and, based on the system messages, detects whether the neighboring frequency points of SIB5-NB are added to the neighboring cell list of the current serving cell. It also detects the period and sending time of SIB2-NB, SIB3-NB, and SIB5-NB, analyzes and determines whether the terminal can reselect a cell to a new frequency point, and outputs the corresponding detection reason.

[0072] In this embodiment, the problem of terminals being unable to access the network after frequency refarming in some NB-IoT areas is solved. This makes it easier for non-professionals to detect and analyze access problems and causes after frequency refarming, and to understand the problems in the NB-IoT network in a timely manner. There is no need for professional testers to capture logs for testing and verification, saving manpower and time.

[0073] For areas where frequencies have been refarmed, the specific reasons why some terminals may be unable to access the network are as follows:

[0074] I. Network-side reasons:

[0075] (1) No new frequency points were added to the neighboring cells of SIB5-NB: The UE accesses the old frequency point EARFCN in a distant area based on the historical camping frequency point. legacy In some cells with poor network signal, the serving cell where the UE is located has not included the new frequency point in the neighbor cell information. After receiving the SIB2-NB, the UE accesses the historical cell but cannot find the new frequency point information (nearby cell). The terminal cannot reselect to the new frequency point cell with better signal, resulting in the NB-IoT UE being unable to access the network.

[0076] (2) SIB3-NB and SIB5-NB periods are longer than SIB2-NB periods: The serving cell where the UE is located includes the new frequency point in the neighbor cell information. The SIB3-NB and SIB5-NB periods are longer than the SIB2-NB period. After receiving SIB2-NB, the UE accesses the historical cell. The UE does not receive SIB3-NB and SIB5-NB simultaneously, and cannot perform neighbor cell measurement in a timely manner (e.g. Figure 3 As shown in the image, the UE is unable to reselect a new frequency cell with a better signal, resulting in the NB-IoT UE being unable to access the network.

[0077] (3) SIB3-NB and SIB5-NB have the same cycle as SIB2-NB, but are not sent simultaneously: The cell where the UE is located includes the new frequency point in the neighbor cell information. SIB3-NB and SIB5-NB have the same cycle as SIB2-NB, but are not sent simultaneously. After receiving SIB2-NB, the UE accesses the historical cell. The NB-IoT UE does not perform neighbor cell measurement in time, and the UE cannot reselect to the new frequency point cell with better signal, resulting in the NB-IoT UE being unable to access the network. (SIBn messages with the same cycle can be sent simultaneously in the same SI or in different SIs.)

[0078] II. Terminal-side reasons:

[0079] (1) The terminal was powered off for a short time and did not reselect in time: The UE accessed the old frequency EARFCN in a remote area based on the historical camping frequency. legacy If a cell fails to send data within a certain time (e.g., 3 minutes), and after several repeated attempts, the communication module is shut down, the UE has a short standby time in the NB-IoT network and cannot trigger cell reselection.

[0080] (2) The terminal was powered off for a short time and did not reselect the full frequency band in time: The UE accessed the cell of the old frequency point EARFCNlegacy in a remote area. The standby time in the NB-IoT network is short and it cannot start the full frequency band search.

[0081] See Figure 3 The specific steps include:

[0082] Step 1: Activate the frequency re-tillage detection function.

[0083] Step 2: After activating the frequency refarming detection function, enter or select the new frequency point EARFCN after frequency flipping. new .

[0084] Step 3: Measure near the problem cell (a problem cell is one where some terminals cannot access the network), and camp on the problem cell (i.e., the old frequency point EARFCN). legacy (residential community).

[0085] Step 4: If a problem cell (i.e., an old frequency point EARFCN) is found legacy The system initiates the message receiving process for the residential community and then camps on the community.

[0086] It receives system messages broadcast by the base station, reads the period (si-Periodicity) and broadcast position (si-RadioFrameOffset) of SIB2-NB, SIB3-NB, and SIB5-NB from SIB1-NB, reads the service radio resource management information configuration from SIB2-NB, reads the same-frequency measurement and reselection information from SIB3, and reads the different-frequency measurement and reselection information and the different-frequency point list (interFreqCarrierFreqList) from SIB5-NB.

[0087] Step 5: Input the new frequency point EARFC Nnew Compare with the frequency list of neighboring cells in the serving cell;

[0088] The serving cell neighbor frequency list is the SIB5-NB inter-frequency list (frequency carrierFreq in intraFreqCarrierFreqList) obtained from base station broadcast.

[0089] Step 6: If the new frequency EARFCN is not in the neighboring frequency list of the serving cell. new Then output the new frequency point EARFCN new Not added to the neighboring frequency list of the serving cell.

[0090] Step 7: If the new frequency EARFCN exists in the neighboring frequency list of the serving cell... new Then continue to compare the SIB2-NB with SIB3-NB and SIB5-NB cycles obtained from the base station broadcast.

[0091] Step 8: If the periods of SIB2-NB are different from those of SIB3-NB and SIB5-NB, then there is a frequency change problem in the output. The period settings of SIB2-NB, SIB3-NB and SIB5-NB are not reasonable. It is necessary to ensure that the periods of SIB3-NB, SIB5-NB and SIB2-NB are consistent.

[0092] Step 9: If SIB2-NB has the same cycle as SIB3-NB and SIB5-NB, then continue to determine whether SIB2-NB, SIB3-NB and SIB5-NB are obtained in the same SI message, that is, check whether sibType3-NB-r13 and sibType5-NB-r13 are in the first ScheduledInfo-NB message of SIB1-NB (SIB2 is in the first ScheduledInfo-NB message and does not have sib-MappingInfo information).

[0093] Step 10: If SIB2-NB is not transmitted simultaneously with SIB3-NB and SIB5-NB, there will be a frequency change issue in the output. If SIB2-NB is not transmitted simultaneously with SIB3-NB and SIB5-NB, it is necessary to ensure that SIB3-NB, SIB5-NB and SIB2-NB transmit simultaneously.

[0094] Step 11: If SIB2-NB, SIB3-NB, and SIB5-NB are in the same SI information, then there is no issue with access after frequency refarming.
