[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments:

[0035] Embodiment 1:

[0036] Figure 1AThe implementation process of the method for monitoring cell signal quality provided in the first embodiment of the present invention is shown. For the convenience of description, only the part related to the embodiment of the present invention is shown, which is described in detail as follows:

[0037] In step S101, a measurement and control strategy of a target cell is configured, where the measurement and control strategy includes information of devices to be tracked and measurement and control content corresponding to each device to be tracked.

[0038] The embodiment of the present invention is applied to the base station side. In the embodiment of the present invention, the target cell generally refers to a specific cell such as a private network coverage area or a confidential area, and the target cell provides services for a specific user equipment. The measurement and control content corresponding to each device to be tracked is set according to the actual measurement requirements, and the measurement and control content may include A2 event measurement and B1 event measurement, etc. When configuring the measurement and control strategy, preferably, the measurement and control strategy is configured based on the ID of the device to be tracked, so as to monitor the cell signal quality through the ID of the device to be tracked.

[0039] When configuring the measurement and control strategy based on the ID of the device to be tracked, preferably, the IMSI (International Mobile Subscriber Identity) information of the device to be tracked is configured, and the corresponding measurement and control content is configured for the IMSI information, so as to configure the measurement and control strategy according to the IMSI information of the device, thereby improving the pertinence of the subsequent configuration information issuance and the monitoring effect of the cell signal quality. Specifically, when there are multiple devices to be tracked, the IMSIs of multiple devices to be tracked can be configured at the same time, and the corresponding measurement and control content can be configured for each IMSI, and the measurement and control content corresponding to each IMSI can be the same or different.

[0040] When configuring the measurement and control strategy based on the ID of the device to be tracked, another preferred embodiment is to configure the grouping rules, and configure the corresponding measurement and control content for the IMSI information under the preset group based on the grouping rules, so as to implement the configuration of the measurement and control strategy through the devices under the specific group. Considering the security of private network users, preferably, the grouping rules include grouping based on different PLMNs (public land mobile networks PLMNs), so as to implement the configuration of the measurement and control strategy through the devices under the specific PLMN group, thereby ensuring the security of monitoring the cell signal quality.

[0041] When configuring the measurement and control strategy, another preferred embodiment configures the measurement and control strategy based on the distribution area of ​​the device to be tracked, so as to monitor the cell signal quality through the distribution area of ​​the device to be tracked and improve the pertinence of the monitoring of the cell signal quality.

[0042] When configuring the measurement and control strategy based on the distribution area of ​​the device to be tracked, preferably, the area division rule is configured, and the corresponding measurement and control content is configured for the IMSI information of the device to be tracked that meets the preset conditions and is distributed in each area based on the area division rule, so as to realize the configuration of the measurement and control strategy by configuring the area division rule, further enrich the configuration mode of the measurement and control strategy, and improve the effect of monitoring the cell signal quality. Among them, the preset condition includes that the signal to interference plus noise ratio in the target cell is lower than the special stop threshold.

[0043] Preferably, the regional distribution rules support multi-level regional division, and the regional division rules include one or more of regional division based on reference signal received power (RSRP, Reference Signal Receiving Power), regional division based on reference signal received quality (RSRQ, Reference Signal Receiving Quality), and regional division based on signal to interference plus noise ratio (SINR, Signal to Interference plus Noise Ratio), so as to configure the measurement and control strategy according to actual test needs.

[0044] As an example, the device to be tracked is divided into two areas, an edge area and a sub-edge area, according to SINR. The measurement and control content configured for the IMSI information in the edge area is B1 event measurement, and the measurement and control content configured for the IMSI information in the sub-edge area is A2 event measurement. Among them, the B1 event measurement is specifically to detect whether the signal quality of the neighboring area of ​​the heterogeneous system is higher than a predetermined threshold (first threshold) within a preset time length. If so, the device to be tracked generates a B1 measurement report, and the A2 event measurement is specifically to detect whether the signal of the target cell is worse than a predetermined threshold (second threshold) within a preset time length. If so, the user equipment generates an A2 measurement report.

[0045] In step S102, configuration information is sent to the device to be tracked based on the measurement and control strategy, where the configuration information is used to instruct the device to be tracked to send a measurement report based on the received measurement and control content.

[0046] In the embodiment of the present invention, the device to be tracked is in a signal transition area of ​​a target cell, and the device to be tracked accesses the target cell in the signal transition area. Figure 1B A schematic diagram of the community. Figure 1B The target cell in the image includes an internal signal area (inner circle) 10 and a signal transition area (outer circle) 11. The internal signal area is a restricted area, the signal transition area is an area with weak coverage of the internal signal, and the area outside the signal transition area is a no-signal area 12, which is an area that cannot be covered by the internal signal. The device to be tracked is in Figure 1B The plane position or spatial position of the signal transition region described in .

[0047] When sending configuration information to the device to be tracked based on the measurement and control strategy, specifically, the configuration can be performed based on the measurement and control strategy to enable the measurement and control strategy, and then a request message is sent to the SMF (Session Management Function) through the AMF (Access and Mobility Management Function), and the request message is used to request the first temporary identification information corresponding to each IMSI information, obtain the second temporary identification information based on the first temporary identification information, and send the configuration information to the target device corresponding to the second temporary identification information. Among them, the request message can use the MR information request message in the NGAP protocol (NG Application Protocol), the first temporary identification information can be TMSI (Temporary Mobile Subscriber Identity), GUTI (Globally Unique Temporary UE Identity), etc., and the second temporary identification information can be RNTI (Radio Network Temporary Identity), UEID (UE identification), etc.

[0048] In the specific implementation, the base station forwards the request message to SMF through AMF to request the TMSI, GUTI and other information corresponding to the IMSI. For example, the MR information request message in the NGAP protocol is used, and the list of base stations allowed to be accessed is pre-added in AMF. If the base station sending the request message exists in the base station list, the AMF forwards the MR information request message to SMF, otherwise it returns the MR information reject message, and SMF sends the corresponding message requested by the above message to AMF, for example, using the NGAP protocol -MR information response message, and forwards it back to the base station. The base station performs a one-to-one match with the RNTI, UEID and other information of the device to be tracked through the query of the TMSI, GUTI and other information. After matching the corresponding information, the base station sends the corresponding configuration information queried to the corresponding device to be tracked.

[0049] After receiving the above configuration information, the device to be tracked parses the configuration information and configures it to enable the device to be tracked. The device to be tracked reports the measurement report according to the measurement and control content in the configuration information.

[0050] In step S103, the received measurement report sent by the device to be tracked is forwarded to the receiving server, so that the receiving server monitors the signal quality of the target cell based on the measurement report and the location information of the device to be tracked.

[0051] In an embodiment of the present invention, after receiving the measurement report sent by the device to be tracked, the base station may process the measurement report and forward it to an external receiving server. The receiving server may monitor whether the signal of the target cell changes according to the received measurement report and the location information of the device to be tracked, and may issue an alarm when the signal of the target cell changes, so as to promptly remind the staff to conduct an investigation when the signal of the target cell changes. Specifically, the change in the signal of the target cell may include the target cell signal becoming stronger in the current monitoring area, the target cell signal becoming weaker in the current monitoring area, or other measurement signals becoming stronger in the current monitoring area. Among them, the location information of the device to be tracked may be returned by the device to be tracked based on GPS or Beidou positioning, etc., or may be returned after the base station or other devices connected to the base station calculate the location information of the device to be tracked.

[0052] In an embodiment of the present invention, a measurement and control strategy of a target cell is configured, the measurement and control strategy includes information of a device to be tracked and measurement and control content corresponding to each device to be tracked, configuration information is sent to the device to be tracked based on the measurement and control strategy, the configuration information is used to instruct the device to be tracked to send a measurement report based on the received measurement and control content, the device to be tracked accesses the target cell in a signal transition area, and forwards the received measurement report sent by the device to be tracked to a receiving server, so that the receiving server monitors the signal quality of the target cell based on the measurement report and the location information of the device to be tracked, thereby configuring the measurement and control strategy for a specific device deployed in a specific area, and monitoring the signal quality of a specific cell is achieved based on the configured measurement and control strategy, thereby improving the pertinence of sending measurement messages and ensuring the monitoring effect of the cell signal quality.
