When the UE measures the air interface, it finds that the signal of the cell is lower than a certain threshold and the neighboring cell is higher than a certain threshold and reports the measurement result (measurement) Report). Then, the base station informs the neighboring cell to perform handover preparation for the UE by using the handover request, and then passes the handover command (RRC connection). Reconfiguration) to initiate handover, the UE randomly accesses the random access channel RACH and the time advance value TA (timing) The acquisition of the advanced is synchronized to the new cell, thereby completing the handover process.

 【detailed description】

The invention will now be described in detail in conjunction with the drawings and embodiments.

Referring to FIG. 1 , FIG. 1 is a flowchart of a method for measuring a key performance indicator KPI of a wireless network according to the present invention. This embodiment is a method flow performed by a user equipment, and includes:

Step S101: The user equipment records the measurement information when the wireless connection is abnormal, and the measurement information includes at least the first information and the second information, where the first information is at least one signaling step before the wireless connection abnormality of the user equipment and the cell occurs, and the second information is The cell identifier, latitude and longitude or cell identifier and latitude and longitude of the cell in which the user equipment wirelessly connects abnormally.

User equipment (UE, User Equipment) is an important concept in mobile communication. In 3G and 4G networks, the user terminal is called a UE, and the UE here includes a mobile phone, a smart terminal, a multimedia device, a streaming media device, and the like.

The wireless connection abnormality includes at least one of a user equipment and a wireless side interrupt connection, a high error rate caused by high interference or a high error block rate, and a failure of the user equipment itself. For example, when the vulnerability is covered, the user equipment is disconnected from the wireless side; although the user equipment is connected to the wireless side, the high interference in the neighboring area causes a high bit error rate or a high error rate; the user equipment itself is faulty and causes connection with the wireless side. abnormal.

The first information is at least one signaling step before the user equipment and the cell wireless connection abnormality occur, that is, the signaling step of the previous step when the wireless connection between the user equipment and the cell is abnormal. Through the first information, it can be known which signaling step occurs in the wireless connection abnormality with the cell, so that the cause of the wireless connection abnormality can be found.

The second information is a cell identifier, a latitude and longitude or a cell identifier and a latitude and longitude of a cell that is abnormally connected to the user equipment. The cell identifier can be used to know which cell has a wireless connection abnormality with the user equipment. The latitude and longitude of the cell can be used to know the specific location of the wireless connection abnormality with the user equipment, such as occurring in the middle of the cell, occurring on the east-north edge of the cell, etc. Etc.; through the cell identity and latitude and longitude, it can be known which cell is in a wireless connection abnormality with the user equipment.

When the wireless connection is abnormal, the user equipment records measurement information including at least the first information and the second information, so as to send the measurement information to the wireless side when the wireless side is reconnected, and the wireless side searches for the cause of the abnormal connection of the network.

It should be noted that, when the user equipment is abnormal in the wireless connection, the step of recording the measurement information may be performed under the instruction of receiving the measurement control information of the wireless side, or the user equipment may actively perform the step. No specific restrictions are imposed.

The measurement report further includes third information, where the third information is a signal strength of a cell that is abnormally connected to the user equipment, wherein the signal strength includes a reference signal received power RSRP and a reference signal received quality RSRQ.

Reference Signal Receiving Power (RSRP, Reference Signal Receiving Power) It is one of the key parameters of the LTE network that can represent the wireless signal strength and one of the physical layer measurement requirements. It is an important indicator to measure the wireless network coverage of the system. RSRP indicates the absolute value of the received signal strength, which can reflect the distance of the user equipment from the base station to a certain extent, so it can be used to measure the coverage of the cell. Specifically, RSRP is the average of the signal power received on all resource particles RE carrying a reference signal within a certain symbol.

Received signal strength indicator (RSSI, Received Signal Strength) Indication) is an optional part of the wireless transmission layer used to determine the quality of the connection and whether to increase the broadcast transmission strength.

Reference signal reception quality (RSRQ, Reference Signal Receiving Quality) is the ratio of RSRP to RSSI. For the LTE system, when the network requirements such as the system coverage, the number of users, and the edge rate are determined, the cell reference signal EPRE set based on the link budget and the service model is a constant, and other channel powers are set based on this value, so The reference signal RSRQ is obtained, and the signal-to-noise ratio SNR of other channels can be determined to some extent.

By measuring the third information of the report, it may be helpful to more clearly determine the cause of the abnormality of the wireless connection of the user equipment. For example, if the signal strength of the cell with abnormal wireless connection with the user equipment is relatively strong, it may be that the neighboring area has high interference or the user. The wireless connection caused by the device failure is abnormal. If the signal strength of the cell with abnormal wireless connection with the user equipment is weak, the wireless connection may be abnormal due to weak coverage.

Step S102: After establishing the connection with the wireless side, the user equipment sends a measurement report including the first information and the second information to the wireless side that establishes the connection, so that the wireless side performs the analysis of the KPI indicator according to the measurement report.

Key Performance Indicators (KPI, Key Performance Indication) is the most direct reflection of network quality, including the following major categories: accessibility indicators, retention indicators, mobility indicators, traffic volume indicators, product operation indicators, system availability indicators, and network resource utilization indicators. Through the monitoring of these indicators, it is possible to identify the cells with sudden problems, early warning of risks, stability and improve network quality. For example, the accessibility indicator includes a radio resource control protocol RRC connection establishment success rate, an evolved universal land-based radio access network radio access bearer E-RAB establishment success rate, a wireless connection rate, etc.; the retention indicator includes a wireless drop call Rate (E-RAB abnormal release), etc.; mobility indicators include handover success rate in a cell base station, handover success rate between cell base stations, and the like.

After the user equipment establishes a connection with the wireless side again, that is, after the wireless connection between the user equipment and the wireless side is normal, the user equipment sends a measurement report including the first information and the second information to the wireless side that establishes the connection, according to the first information and the second information. The measurement report of the information, the wireless side can analyze the KPI indicator to obtain the evaluation of the network quality.

The wireless side is a base station or a network management device.

In summary, in the embodiment of the present invention, the user equipment records measurement information including at least the first information and the second information when the wireless connection is abnormal. The first information is at least one signaling step before the wireless connection abnormality of the user equipment and the cell occurs, and the second information is The cell identity, latitude and longitude or cell identity and latitude and longitude of the cell that is abnormally connected to the user equipment are wirelessly connected; after establishing the connection with the wireless side again, the measurement report including the first information and the second information is sent to the established wireless side. Since the reported measurement report includes the first information and the second information, in particular, the wireless side can learn, according to the first information, which step of the signaling step occurs when the user equipment is in a wireless connection abnormality, thereby determining the wireless connection according to the KPI root cause analysis process. The cause of the exception. In this way, it is possible to locate the details of the details of the wireless connection, thereby providing a basis for subsequent network optimization.

The first information is a signaling step of the previous step when the user equipment and the cell are at least one signaling step before the wireless connection abnormality occurs, that is, when the wireless connection between the user equipment and the cell is abnormal. Through the first information, it can be known which signaling step occurs in the wireless connection abnormality with the cell, so that the cause of the wireless connection abnormality can be found.

The second information is a cell identifier, a latitude and longitude or a cell identifier and a latitude and longitude of a cell that is abnormally connected to the user equipment. The cell identifier can be used to know which cell has a wireless connection abnormality with the user equipment. The latitude and longitude of the cell can be used to know the specific location of the wireless connection abnormality with the user equipment, such as occurring in the middle of the cell, occurring on the east-north edge of the cell, etc. Etc.; through the cell identity and latitude and longitude, it can be known which cell is in a wireless connection abnormality with the user equipment.

When the wireless connection is abnormal, the user equipment records measurement information including at least the first information and the second information, so as to send the measurement information to the wireless side when the wireless side is reconnected, and the wireless side searches for the cause of the abnormal connection of the network.

The measurement report further includes third information, where the third information is a signal strength of a cell that is abnormally connected to the user equipment, wherein the signal strength includes a reference signal received power RSRP and a reference signal received quality RSRQ.

RSRP is one of the key parameters of the LTE network that can represent the wireless signal strength and one of the physical layer measurement requirements. It is an important indicator to measure the coverage of the wireless network of the system. Specifically, RSRP is the average of the signal power received on all resource particles RE carrying a reference signal within a certain symbol. The RSSI is an optional part of the wireless transmission layer used to determine the quality of the connection and whether to increase the broadcast transmission strength. RSRQ is the ratio of RSRP to RSSI. For the LTE system, when the network requirements such as the system coverage, the number of users, and the edge rate are determined, the cell reference signal EPRE set based on the link budget and the service model is a constant, and other channel powers are set based on this value, so The reference signal RSRQ is obtained, and the signal-to-noise ratio SNR of other channels can be determined to some extent.

By measuring the third information of the report, it may be helpful to more clearly determine the cause of the abnormality of the wireless connection of the user equipment. For example, if the signal strength of the cell with abnormal wireless connection with the user equipment is relatively strong, it may be that the neighboring area has high interference or the user. The wireless connection caused by the device failure is abnormal. If the signal strength of the cell with abnormal wireless connection with the user equipment is weak, the wireless connection may be abnormal due to weak coverage.
