Abstract
Description
Technical Field
[0001] The present application relates to the field of wireless communication technology, and in particular to a method and device for adjusting network parameters. Background Art
[0002] Due to uplink interference, existing wireless networks often experience problems such as network access failure or data transmission failure even though the terminal's downlink signal Reference Signal Received Power (RSRP) and Signal to Interference plus Noise Ratio (SINR) are very good. Alternatively, although the downlink signal RSRP and SINR are slightly lower but still within the required range, network access is difficult or access latency is very long, leading to frequent customer complaints. When such problems occur, troubleshooting personnel will usually manually adjust the base station's network optimization parameters to circumvent the problem, such as increasing the terminal's initial transmit power or reducing the base station's coverage range, if the problem is confirmed to be caused by uplink interference. However, if these network optimization parameters cannot be adjusted in a timely manner if the uplink interference subsequently changes, the network will still have a significant impact.

[0075] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.
[0076] See also Figure 1 , Figure 1 A flow chart of a network parameter adjustment method provided in Example 1 of the present application includes the following steps:
[0077] Step 11: Determine an adjustment value of a network parameter of the second cell based on the first information of the first cell and a pre-established table or uplink interference service model;
[0078] The first information is related information of the first cell. In the embodiment of the present application, there are two different ways to determine the adjustment value of the network parameter of the second cell: first, based on the first information of the first cell, query a pre-established table to obtain the adjustment value of the network parameter of the second cell; second, input the first information of the first cell into a pre-trained uplink interference service model, and then determine the adjustment value of the network parameter of the second cell based on the output of the uplink interference service model.
[0079] The adjustment value of the network parameter is an adjustment offset or an adjustment expected value, the network parameter includes an initial transmit power parameter of the terminal and / or a different coverage area access parameter, and the first cell includes at least the second cell.
[0080] The different coverage area access parameters are also known as base station coverage level range parameters, which are used to determine the base station coverage level range. Network parameters can also be called base station parameters. The adjustment offsets of each network parameter can be the same or different.
[0081] The network parameter adjustment method provided in the embodiment of the present application is an intelligent network parameter dynamic optimization method for uplink interference. It can automatically determine the adjustment offset or adjustment expected value of the network parameter of the second cell based on the first information of the first cell including at least the second cell, so that the second cell can automatically adjust the initial transmission power parameters of the terminal and / or access parameters of different coverage areas according to the determined adjustment value, quickly adapt to changes in the wireless network, effectively avoid uplink interference, and at the same time will not cause negative impact on the network.
[0082] The network parameter adjustment method provided in an embodiment of the present invention can be applied to a network management center. After determining an adjustment value for the network parameter of a second cell based on the first information of the first cell, the network management center sends the adjustment value for the network parameter of the second cell to the second cell, so that the second cell adjusts the initial transmit power parameter and / or access parameters for different coverage areas. The network parameter adjustment method provided in an embodiment of the present invention can also be applied to other devices other than the network management center, such as a base station, specifically a base station corresponding to the second cell.
[0083] The following example illustrates the above network parameter adjustment method.
[0084] In the embodiment of the present application, when determining the adjustment value of the initial transmit power parameter and / or the access parameter of different coverage areas of the terminal in the second cell according to the first information of the first cell, there are two ways:
[0085] 1. Adjustment method based on table lookup. For example, the network management center can select the appropriate adjustment offset based on the uplink interference (i.e. uplink noise floor), load conditions and radio resource control (RRC) connection success rate of the first cell (including the second cell and its surrounding cells) by table lookup. Change , so that the initial power parameter P of random access of the second cell is PRACH_NEW , uplink traffic channel initial power parameter P PUSCH_NEW And the access parameter RSRP-ThresholdsPrachInfoList (if any) of different coverage areas of the cell is adjusted as follows: PRACH_NEW =P PRACH +Offset Change ;P PUSCH_NEW =P PUSCH +Offset Change ; Each value in RSRP-ThresholdsPrachInfoList increases by Offset ChangeAt the same time, ensure that the interference increase to the surrounding cells after adjustment is within the allowable range (Note: Raising the initial power parameters of terminal random access and the initial power parameters of the uplink service channel, such as the increase in the network load of this cell, will cause a certain degree of uplink interference to the surrounding cells, so it is necessary to examine the impact on the surrounding cells).
[0086] Second, artificial intelligence (AI) reasoning and calculation. For example, the network management center trains based on the uplink noise floor, network load, initial transmission power parameters of cell terminals, and RRC connection success rate data regularly reported by each cell in the entire area to form Figure 2 The uplink interference business model shown in Figure 2 is shown in Figure 2. Figure 2 , if an uplink interference change occurs in a certain cell (the second cell), the changed uplink interference is input into the business model for inference calculation, and the adjusted initial transmission power parameter of the cell terminal (i.e., the adjusted expected value of the initial transmission power parameter of the terminal) is output, and the access parameter RSRP-ThresholdsPrachInfoList (if any) of different coverage areas of the cell is adjusted accordingly. Specifically, based on the adjusted initial transmission power parameter of the cell terminal and the initial transmission power parameter of the cell terminal before adjustment, the adjustment offset of the initial transmission power parameter of the terminal is calculated, and the adjustment offset is used as the adjustment offset of the access parameter of different coverage areas of the cell, or the adjustment offset of the access parameter of different coverage areas of the cell is calculated based on the adjustment offset of the initial transmission power parameter of the terminal. The embodiment of the present application can comprehensively consider multiple cells and realize refined adjustment of the parameters of multiple cells to avoid affecting the remaining cells due to adjustment of some cells.
[0087] Optionally, the first information includes at least one of uplink noise floor, network load and radio resource control (Radio Resource Control, RRC) connection success rate.
[0088] Optionally, the first cell also includes surrounding cells of the second cell.
[0089] Optionally, determining the adjustment value of the network parameter of the second cell includes:
[0090] Determine an adjustment value of a network parameter of the second cell and an adjustment value of a network parameter of neighboring cells of the second cell.
[0091] Afterwards, the second cell may adjust its network parameters according to the determined adjustment values of the network parameters of the second cell, and the neighboring cells of the second cell may adjust their network parameters according to the determined corresponding adjustment values of the network parameters.
[0092] For example, when the network parameter adjustment method is applied to the network management center, the network management center determines the adjustment value of the network parameter of the second cell and the adjustment value of the network parameter of the surrounding cells of the second cell, and sends the determined adjustment value of the network parameter to the corresponding cell, so that the corresponding cell adjusts the network parameter according to the adjustment value.
[0093] The embodiments of the present invention can comprehensively consider multiple cells and implement refined adjustment of parameters of multiple cells, thereby preventing the adjustment of some cells from affecting other cells.
[0094] Optionally, the initial transmit power parameter includes a random access initial power parameter and / or an uplink service channel initial power parameter.
[0095] Optionally, before determining the adjustment value of the network parameter of the second cell based on the first information of the first cell and based on a pre-established table or uplink interference service model, the method further includes:
[0096] Obtaining a signal-to-noise ratio (SNR) of an initial random access channel of the second cell; determining whether the random access initial power parameter of the terminal in the second cell needs to be adjusted according to whether the SNR of the initial random access channel of the second cell meets a first preset condition;
[0097] and / or,
[0098] Obtain the SNR of the initial service channel of the second cell; determine whether the initial power parameter of the uplink service channel of the terminal in the second cell needs to be adjusted based on whether the SNR of the initial service channel of the second cell meets the second preset condition.
[0099] The first preset condition may be greater than a first preset value, and the second preset condition may be greater than a second preset value.
[0100] In the embodiment of the present application, when the network parameter adjustment method is applied to the network management center, the second cell regularly reports the uplink background noise Noise to the network management center. UP and network load conditions, the network management center performs uplink interference parameter adaptation detection based on the uplink noise floor reported by the second cell.
[0101] Parameter adaptation detection method: Get the cell parameters, i.e. the random access initial power parameter P PRACH (Take the Narrow Band Internet of Things (NB-IoT) as an example, the parameter preambleInitialReceivedTargetPower) and the uplink service channel initial power parameter P PUSCH(Take NB-IoT as an example, that is, p0-NominalPUSCH.) If there are access parameters for different coverage areas of the cell, obtain the corresponding parameters, that is, RSRP-ThresholdsPrachInfoList (Take NB-IoT as an example, RSRP-ThresholdsNPRACH-InfoList-NB-r13).
[0102] Estimate the SNR of the initial random access and traffic channel on the uplink base station side, SNR PRACH =P PRACH -Noise UP and SNR PUSCH =P PUSCH -Noise UP .
[0103] Such as SNR PRACH and SNR PUSCH Both are greater than Offset UP , then determine the random access initial power parameter P PRACH and the initial power parameter P of the uplink traffic channel PUSCH Reasonable settings.
[0104] Such as SNR PRACH and SNR PUSCH The value is less than Offset for a period of time. UP , then determine the random access initial power parameter P PRACH and the initial power parameter P of the uplink traffic channel PUSCH Needs adjustment.
[0105] Optionally, determining the adjustment value of the network parameter of the second cell includes:
[0106] determining, according to the first information of the first cell, an adjustment value of an initial transmit power parameter of a terminal in the second cell;
[0107] The adjustment value of the different coverage area access parameter in the second cell is determined according to the adjustment value of the initial transmit power parameter of the terminal in the second cell.
[0108] The adjustment offset of the different coverage area access parameter may be the same as or different from the adjustment offset of the initial transmit power parameter of the terminal.
[0109] Optionally, before determining the adjustment value of the network parameter of the second cell based on the uplink interference service model according to the first information of the first cell, the method further includes:
[0110] Training the uplink interference service model based on the first information and network parameters reported multiple times by multiple third cells;
[0111] The plurality of third cells include the first cell. The third cells may include cells in an entire area, for example, all cells under the jurisdiction of a network management center.
[0112] For example, see Figure 2 When conducting AI training, the uplink noise floor, network load, and RRC connection success rate of each third cell are used as input vector parameters, and the initial transmission power parameters of the cell terminal are used as output parameters. The middle layer can be one layer or multiple layers, and different activation functions can be used depending on the number of layers selected. The purpose of data training is to obtain the fitting relationship from input to output, that is, the various parameters between the input, middle layer, and output. When the AI training results are gradually fitted and a stable neural network matrix is obtained, the expected terminal initial transmission power parameters of each cell can be obtained based on the uplink noise floor, expected network load, and expected RRC connection success rate of each relevant cell, and the access parameters RSRP-ThresholdsPrachInfoList (if any) of different coverage areas of the cell can be adjusted accordingly.
[0113] Optionally, after determining the adjustment value of the network parameter of the second cell, the method further includes:
[0114] sending the adjusted value of the network parameter of the second cell to the second cell, so that the second cell adjusts the network parameter;
[0115] monitoring an SNR of an initial random access channel and / or an SNR of an initial traffic channel of the second cell and cells surrounding the second cell;
[0116] If at least one of the following conditions exists, a parameter configuration fallback request is sent to the second cell: the SNR of the initial random access channel of the second cell does not meet the first preset condition; the SNR of the initial random access channel of the neighboring cells of the second cell does not meet the first preset condition; the SNR of the initial traffic channel of the second cell does not meet the second preset condition; the SNR of the initial traffic channel of the neighboring cells of the second cell does not meet the second preset condition;
[0117] Re-determine the adjustment value of the network parameter of the second cell.
[0118] In the embodiment of the present application, the network management center establishes a signaling channel with each cell to interact with each other for adjusting the uplink interference parameters. For example, the network management center sends a parameter configuration modification request to the second cell and / or the surrounding cells of the second cell (the request needs to ensure that the parameters can be rolled back when a problem occurs, that is, the cell needs to retain the original parameter configuration), that is, the network management center requires the cell to change the random access initial power parameter P PRACH and the initial power parameter P of the uplink traffic channelPUSCH Adjust according to the new value (expected value). After the parameter configuration takes effect, the network management center continuously monitors the uplink noise floor of the cell and its surrounding cells. UP The network load and adaptability test are performed. If everything is normal, the network management center sends a confirmation modification to the cell. If an abnormality occurs (in this cell or a neighboring cell), the network management center needs to send a parameter configuration rollback request to the cell and recalculate the appropriate parameters.
