[0060] The technical solutions in the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of the present application.

[0061] The terms "first", "second", etc. of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of one type, and the number of objects is not limited, for example, the first object can be one or more. In addition, "or" in the present application represents at least one of the connected objects. For example, the protection scope of "A or B" covers at least three schemes, that is, scheme one: including A and excluding B; scheme two: including B and excluding A; scheme three: including both A and B. In addition, the terms "A and / or B", "at least one of A and B", and "at least one of A or B" also cover at least the above three schemes respectively. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0062] The core of the present application is to provide a voice coverage interoperability threshold adjustment method, which can be applied to optimization scenarios of mobile communication networks, such as voice service optimization scenarios of mobile communication networks.

[0063] In the embodiment of the present application, the voice coverage interoperability threshold can be understood as a voice switching threshold based on reference signal received power (RSRP).

[0064] As described above, in the related art, the voice coverage interoperability threshold of each cell is uniformly set mainly based on the experience of field experts. It is not considered that there are differences between different cells, which leads to differences in the optimal voice coverage interoperability threshold. In other words, this "one-size-fits-all" approach leads to unreasonable settings of voice coverage interoperability thresholds in some cells, affecting the call perception and satisfaction of mobile voice users. When facing complaints about the voice coverage interoperability threshold, it is often simply to adjust the threshold for a single user to solve the complaint problem of a single user, without configuring the optimal voice coverage interoperability threshold at the cell level. In addition, in the related art, the manufacturer's network management has a configuration based on packet loss rate switching. During the process of the user performing voice services, it takes several seconds of packet loss rate detection to determine and control the terminal to switch, and the response time is long. In addition, it is necessary to rely on manual actual testing of each cell and configure the voice coverage interoperability threshold adapted to the cell, which will cost a lot of manpower and time costs when the communication facilities are large in scale.

[0065] It is understandable that in the voice service of the mobile communication network, there are two key measurement indicators: "getting through" and "hearing clearly". Among them, "getting through" and "hearing clearly" are both strongly correlated with the network coverage of the cell where the user terminal accesses. Since the paging success threshold (corresponding to RSRP) of the called terminal is often lower than the threshold of air interface voice packet loss, the voice coverage interoperability threshold of the cell is mainly based on the indicators corresponding to "getting through", such as packet loss rate or mean opinion score (Mean Opinion Score) for tuning. In addition, since in the mobile communication network, the terminal transmission power is much smaller than the base station transmission power, the mobile communication network is an uplink restricted network. When the uplink voice call quality is normal, the downlink voice call quality will basically be normal.

[0066] Based on this, an embodiment of the present application proposes a voice coverage interoperability threshold adjustment method, which finely optimizes and adjusts the voice coverage interoperability threshold of a specific cell based on the uplink coverage situation.

[0067] For ease of understanding, the following first introduces the composition architecture of the system to which the technical solution of this application is applicable. The system includes a base station, a terminal and an application server. The terminal communicates with the base station through a mobile communication network, such as executing data services and voice services. The application server can obtain relevant data of the base station and the terminal and adjust the voice coverage interoperability threshold of a specific cell. Figure 1 As shown, there are terminals 1, 2, and 3 in the coverage of the cell provided by base station 1, and there are terminals 4 and 5 in the coverage of the cell provided by base station 2. The application server can obtain the cell provided by each base station and the relevant data of each terminal. The application server can be deployed on the network management side.

[0068] Specifically, the application server may first determine a first cell that meets the first condition and a second cell that meets the second condition. The first condition is used to indicate whether the voice coverage interoperability threshold can be adjusted, and the second condition is used to indicate whether the voice coverage interoperability threshold does not need to be adjusted. The first cell that meets the first condition is considered to be a cell that can adjust the voice coverage interoperability threshold, and the second cell that meets the second condition is considered to be a cell that does not need to adjust the voice coverage interoperability threshold. Then, the first normalized transmit power corresponding to the voice service of the terminal in the first cell is obtained, and the first normalized transmit power is analyzed to obtain the first transmit power expectation corresponding to the first cell. Similarly, the second normalized transmit power corresponding to the voice service of the terminal in the second cell is obtained, and the second normalized transmit power is analyzed to obtain the second transmit power expectation corresponding to the second cell. Finally, according to the comparison result of the first transmit power expectation and the second transmit power expectation, when it is determined that the voice coverage interoperability threshold of the first cell is adjusted, the adjustment operation of the first cell is triggered. By comparing the first transmission power expectation corresponding to the cell that can adjust the voice coverage interoperability threshold with the second transmission power expectation corresponding to the cell that does not need to adjust the voice coverage interoperability threshold, it is possible to accurately determine whether to adjust the voice coverage interoperability threshold of the first cell. When the judgment result is positive, the corresponding adjustment operation is triggered, which helps to improve the call perception and satisfaction of mobile voice users in the first cell.

[0069] It should be noted that the above description is based on an example in which the application server is an independent server, but it is understandable that in actual applications, the application server can also be replaced by an application server cluster, or a distributed cluster composed of multiple application servers. Figure 1 In the present invention, the application server can also be replaced by an application platform composed of multiple application servers.

[0070] See also Figure 2 As shown, it is a flow chart of an implementation of a voice coverage interoperability threshold adjustment method provided in an embodiment of the present application. The method may include the following steps:

[0071] S210: Determine a first cell that meets a first condition and a second cell that meets a second condition.

[0072] The first condition is used to indicate whether the voice coverage interoperability threshold can be adjusted, and the second condition is used to indicate whether the voice coverage interoperability threshold does not need to be adjusted.

[0073] In the embodiment of the present application, the first condition and the second condition may be set first. The first condition and the second condition may be related to the uplink voice packet loss rate.

[0074] For a cell, by judging whether the cell meets the first condition, it is determined whether the voice coverage interoperability threshold of the cell can be adjusted, and by judging whether the cell meets the second condition, it is determined whether the voice coverage interoperability threshold of the cell does not need to be adjusted. Optionally, if the cell meets the first condition, it is determined that the voice coverage interoperability threshold of the cell can be adjusted. Optionally, if the cell meets the second condition, it is determined that the voice coverage interoperability threshold of the cell does not need to be adjusted.

[0075] There may be multiple first cells that meet the first condition, and for each first cell, the voice coverage interoperability threshold may be adjusted according to the technical solution provided in the embodiment of the present application. There may be multiple second cells that meet the second condition, and one of the multiple second cells may be selected as a comparison reference, or the parameters corresponding to the multiple second cells may be averaged as a comparison reference. The first cell and the second cell may be cells deployed by the same operator.

[0076] S220: Obtain a first normalized transmit power corresponding to a voice service of a terminal in a first cell, and analyze the first normalized transmit power to obtain a first expected transmit power corresponding to the first cell.

[0077] In the embodiment of the present application, the first cell satisfies the first condition, and it is considered that the voice coverage interoperability threshold of the first cell can be adjusted, and it can be considered that there is a need to optimize the voice service of the terminal in the first cell.

[0078] Within the coverage of the first cell, multiple terminals may access the first cell and perform voice services in the first cell. The first normalized transmit power corresponding to the voice services of the terminals in the first cell may be obtained, and each terminal in the first cell may correspond to multiple first normalized transmit powers.

[0079] Optionally, the terminal's transmission power status can be obtained through the terminal background log and associated with the terminal's communication status to obtain the terminal's transmission power status when executing voice services. At the same time, the cell, operator, etc. accessed by the terminal can be distinguished to obtain the first normalized transmission power corresponding to the voice service of the terminal in the first cell.

[0080] The unit of transmit power can be mW.

[0081] After the first normalized transmit power corresponding to the voice service of the terminal in the first cell is acquired, the first normalized transmit power may be analyzed to obtain the first transmit power expectation corresponding to the first cell.

[0082] S230: Obtain a second normalized transmit power corresponding to the voice service of the terminal in the second cell, and analyze the second normalized transmit power to obtain a second expected transmit power corresponding to the second cell.

[0083] In the embodiment of the present application, the second cell meets the second condition, and it is considered that there is no need to adjust the voice coverage interoperability threshold of the second cell, and it can be considered that the voice services of the terminals in the second cell can be carried out smoothly.

[0084] Within the coverage of the second cell, multiple terminals may access the second cell and perform voice services in the second cell. The second normalized transmit power corresponding to the voice services of the terminals in the second cell may be obtained, and each terminal in the second cell may correspond to multiple second normalized transmit powers.

[0085] Optionally, the transmission power of the terminal can be obtained through the terminal background log and associated with the communication status of the terminal to obtain the transmission power of the terminal when executing voice services. At the same time, the cell, operator, etc. accessed by the terminal can be distinguished to obtain the second normalized transmission power corresponding to the voice service of the terminal in the second cell.

[0086] After the second normalized transmit power corresponding to the voice service of the terminal in the second cell is acquired, the second normalized transmit power may be analyzed to obtain the second transmit power expectation corresponding to the second cell.

[0087] It should be noted that the embodiment of the present application has no restriction on the execution order of step S220 and step S230.

[0088] S240: According to the comparison result of the first expected transmit power and the second expected transmit power, when it is determined that the voice coverage interoperability threshold of the first cell is to be adjusted, an adjustment operation on the first cell is triggered.

[0089] In an embodiment of the present application, after respectively obtaining the first transmission power expectation corresponding to the first cell and the second transmission power expectation corresponding to the second cell, the first transmission power expectation can be compared with the second transmission power expectation, and based on the comparison result, it is determined whether to adjust the voice coverage interoperability threshold of the first cell.

[0090] It can be understood that if the first cell meets the first condition, it is considered that the voice coverage interoperability threshold of the first cell can be adjusted, but whether to adjust the voice coverage interoperability threshold of the first cell needs to be determined based on the comparison result of the first transmission power expectation and the second transmission power expectation.

[0091] When it is determined to adjust the voice coverage interoperability threshold of the first cell, an adjustment operation on the first cell may be triggered. Optionally, an adjustment instruction for the voice coverage interoperability threshold may be sent to the first cell through a network management.

[0092] The initial value of the voice coverage interoperability threshold of each cell can be the same value set uniformly. After the voice coverage interoperability threshold of a specific cell is adjusted, the voice coverage interoperability thresholds of different cells may be the same or different. The voice coverage interoperability threshold of each cell is consistent with the actual situation of the corresponding cell and is more targeted.

[0093] Applying the method provided in the embodiment of the present application, first determine a first cell that meets the first condition and a second cell that meets the second condition. The first condition is used to indicate whether the voice coverage interoperability threshold can be adjusted, and the second condition is used to indicate whether the voice coverage interoperability threshold does not need to be adjusted. It can be considered that the first cell that meets the first condition is a cell that can adjust the voice coverage interoperability threshold, and the second cell that meets the second condition is a cell that does not need to adjust the voice coverage interoperability threshold. Then, obtain the first normalized transmit power corresponding to the voice service of the terminal in the first cell, analyze the first normalized transmit power, and obtain the first transmit power expectation corresponding to the first cell. Similarly, obtain the second normalized transmit power corresponding to the voice service of the terminal in the second cell, and analyze the second normalized transmit power to obtain the second transmit power expectation corresponding to the second cell. Finally, according to the comparison result of the first transmit power expectation and the second transmit power expectation, when it is determined that the voice coverage interoperability threshold of the first cell is adjusted, the adjustment operation of the first cell is triggered. By comparing the first transmission power expectation corresponding to the cell that can adjust the voice coverage interoperability threshold with the second transmission power expectation corresponding to the cell that does not need to adjust the voice coverage interoperability threshold, it is possible to accurately determine whether to adjust the voice coverage interoperability threshold of the first cell. When the judgment result is positive, the corresponding adjustment operation is triggered, which helps to improve the call perception and satisfaction of mobile voice users in the first cell.

[0094] In some embodiments of the present application, the first condition may include at least one of an uplink voice packet loss rate being greater than or equal to a first threshold, and the presence of other cells with coverage quality greater than or equal to a second threshold within the coverage range;

[0095] Alternatively, the second condition may include an uplink voice packet loss rate being less than or equal to a third threshold;

[0096] The third threshold is less than or equal to the first threshold.

[0097] In the embodiment of the present application, the first threshold, the second threshold, and the third threshold can be set and adjusted according to actual conditions, such as the first threshold and the third threshold are 2%, and the second threshold is -85dBm. According to the corresponding relationship between daily MOS and packet loss rate, the user call quality is normal when the packet loss rate is less than 2%.

[0098] Optionally, based on the Deep Packet Inspection (DPI) specification, the packet loss of voice services of terminals when using the Internet Protocol (IP) Multimedia Subsystem (IMS) network, such as the packet loss of 5S voice slices, can be identified in the big data platform, and the packet loss of voice services can be associated with specific cells to generate a database table containing information such as packet loss, time, base station and cell identification. Finally, the uplink voice packet loss rate of each cell is aggregated to determine the cells with an uplink voice packet loss rate greater than or equal to the first threshold and the cells with an uplink voice packet loss rate less than or equal to the third threshold.

[0099] It is understandable that, for a cell, if the voice coverage interoperability threshold of the cell is adjusted, some voice users of the cell will switch to other cells, so it is necessary to ensure that there are other cells with better coverage quality within the coverage range of the cell, otherwise the user perception after switching may become worse. Therefore, in an embodiment of the present application, the first condition may include the presence of other cells with coverage quality greater than or equal to the second threshold within the coverage range. Coverage quality can be characterized by RSRP.

[0100] Optionally, if the first condition includes that the uplink voice packet loss rate is greater than or equal to a first threshold, then for a cell, if the uplink voice packet loss rate of the cell is greater than or equal to the first threshold, the cell is considered to meet the first condition.

[0101] Optionally, if the first condition includes that the uplink voice packet loss rate is greater than or equal to the first threshold, and there are other cells with coverage quality greater than or equal to the second threshold within the coverage area, then for a cell, if the uplink voice packet loss rate of the cell is greater than or equal to the first threshold, and there are other cells with coverage quality greater than or equal to the second threshold within the coverage area of ​​the cell, the cell is considered to meet the first condition.

[0102] By setting the first condition and the second condition, the first cell and the second cell can be accurately identified to accurately determine which cells can adjust the voice coverage interoperability threshold and which cells do not need to adjust the voice coverage interoperability threshold.

[0103] In some embodiments of the present application, obtaining a first normalized transmit power corresponding to a voice service of a terminal in a first cell may include the following steps:

[0104] Obtaining actual transmission power corresponding to the voice service of the terminal in the first cell;

[0105] For each terminal in the first cell, determine a first normalized transmit power corresponding to the voice service of the current terminal according to an actual transmit power corresponding to the voice service of the current terminal and a maximum transmit power of the current terminal;

[0106] The current terminal is the terminal targeted by the current operation.

[0107] For the convenience of description, the above steps are combined for explanation.

[0108] In an embodiment of the present application, if the first cell satisfies the first condition, the voice coverage interoperability threshold of the first cell may be adjusted. After determining the first cell, the actual transmission power corresponding to the voice service of the terminal in the first cell may be obtained first. For example, the actual transmission power corresponding to the voice service of the terminal may be obtained through the terminal background log.

[0109] Different types of terminals may have differences in transmission power. To avoid such differences from affecting subsequent judgments, the embodiment of the present application normalizes the actual transmission power corresponding to the voice service of the terminal. For each terminal in the first cell, the first normalized transmission power corresponding to the voice service of the current terminal is determined based on the actual transmission power corresponding to the voice service of the current terminal and the maximum transmission power of the current terminal. The current terminal is the terminal targeted by the current operation.

[0110] Optionally, the first normalized transmit power corresponding to the voice service of the current terminal may be determined according to a ratio of an actual transmit power corresponding to the voice service of the current terminal to a maximum transmit power of the current terminal.

[0111] Optionally, the actual transmission power corresponding to the voice service of the current terminal can be compared with the maximum transmission power of the current terminal to obtain a first normalized value; then the voice service of the current terminal is divided according to the set first time length, and the average of the first normalized values ​​in each of the first time lengths is determined as the first normalized transmission power corresponding to the voice service of the current terminal.

[0112] It can be understood that after obtaining the actual transmit power corresponding to the voice service of the current terminal, the actual transmit power corresponding to the voice service of the current terminal is compared with the maximum transmit power of the current terminal to obtain a first normalized value. In order to standardize long voice and short voice, the voice service of the current terminal can be divided according to the set first duration, and the average of the first normalized values ​​in each first duration is determined as the first normalized transmit power corresponding to the voice service of the current terminal.

[0113] The first duration may be set and adjusted according to actual conditions, such as being set to 1S, that is, the voice service of the current terminal is divided according to 1S, and the mean of the first normalized value of each 1S is calculated to obtain the corresponding first normalized transmit power.

[0114] The following is a possible formula:

[0115]

[0116] Among them, x r Represents the actual transmission power corresponding to the voice service of the current terminal, in mw, x max Represents the maximum transmit power of the current terminal, which can be obtained through the terminal background log. The unit is mw, and x represents x r The corresponding normalized value.

[0117]

[0118] Among them, x p represents the normalized transmit power corresponding to the 1S voice service of the current terminal, that is, the mean of the normalized values ​​corresponding to the 1S voice service, x i represents the normalized value corresponding to the 1S voice service, and n represents the total number of transmit power sampling points corresponding to the 1S voice service.

[0119] For each terminal in the first cell, the normalized value corresponding to the voice service of the terminal is called the first normalized value, and the normalized transmit power corresponding to the voice service of the terminal is called the first normalized transmit power. There are multiple first normalized transmit powers.

[0120] Based on the actual transmit power corresponding to the voice service of the terminal and the maximum transmit power of the terminal, the normalized transmit power can be effectively determined, thereby reducing the judgment error caused by the difference in transmit power of different types of terminals.

[0121] In some embodiments of the present application, obtaining a second normalized transmit power corresponding to a voice service of a terminal in a second cell includes:

[0122] Obtaining an actual transmission power corresponding to a voice service of a terminal in the second cell;

[0123] For each terminal in the second cell, determine a second normalized transmit power corresponding to the voice service of the current terminal according to an actual transmit power corresponding to the voice service of the current terminal and a maximum transmit power of the current terminal;

[0124] The current terminal is the terminal targeted by the current operation.

[0125] For the convenience of description, the above steps are combined for explanation.

[0126] In the embodiment of the present application, the second cell meets the second condition, and there is no need to adjust the voice coverage interoperability threshold of the second cell, and the second cell can be used as an adjustment reference for the first cell. After determining the second cell, the actual transmission power corresponding to the voice service of the terminal in the second cell can be obtained first. For example, the actual transmission power corresponding to the voice service of the terminal can be obtained through the terminal background log.

[0127] Different types of terminals may have differences in transmission power. To avoid such differences from affecting subsequent judgments, the embodiment of the present application normalizes the actual transmission power corresponding to the voice service of the terminal. For each terminal in the second cell, the second normalized transmission power corresponding to the voice service of the current terminal is determined based on the actual transmission power corresponding to the voice service of the current terminal and the maximum transmission power of the current terminal. The current terminal is the terminal targeted by the current operation.

[0128] Optionally, the second normalized transmit power corresponding to the voice service of the current terminal may be determined according to a ratio of an actual transmit power corresponding to the voice service of the current terminal to a maximum transmit power of the current terminal.

[0129] Optionally, the actual transmission power corresponding to the voice service of the current terminal can be compared with the maximum transmission power of the current terminal to obtain a second normalized value; then the voice service of the current terminal is divided according to the set second time length, and the average of the second normalized values ​​in each second time length is determined as the second normalized transmission power corresponding to the voice service of the current terminal.

[0130] It can be understood that after obtaining the actual transmit power corresponding to the voice service of the current terminal, the actual transmit power corresponding to the voice service of the current terminal is compared with the maximum transmit power of the current terminal to obtain the second normalized value. In order to standardize long voice and short voice, the voice service of the current terminal can be divided according to the set second time length, and the average of the second normalized values ​​in each second time length is determined as the second normalized transmit power corresponding to the voice service of the current terminal.

[0131] The second duration can be set and adjusted according to actual conditions, such as being set to 1S, that is, the voice service of the current terminal is divided according to 1S, and the average of the second normalized value of each 1S is calculated to obtain the corresponding second normalized transmit power. The second duration can be the same as or different from the first duration.

[0132] The following is a possible formula:

[0133]

[0134] Among them, x r Represents the actual transmission power corresponding to the voice service of the current terminal, in mw, x max Represents the maximum transmit power of the current terminal, which can be obtained through the terminal background log. The unit is mw, and x represents x r The corresponding normalized value.

[0135]

[0136] Among them, x p represents the normalized transmit power corresponding to the 1S voice service of the current terminal, that is, the mean of the normalized values ​​corresponding to the 1S voice service, x i represents the normalized value corresponding to the 1S voice service, and n represents the total number of transmit power sampling points corresponding to the 1S voice service.

[0137] For each terminal in the second cell, the normalized value corresponding to the voice service of the terminal is called the second normalized value, and the normalized transmit power corresponding to the voice service of the terminal is called the second normalized transmit power. There are multiple second normalized transmit powers.

[0138] Based on the actual transmit power corresponding to the voice service of the terminal and the maximum transmit power of the terminal, the normalized transmit power can be effectively determined, thereby reducing the judgment error caused by the difference in transmit power of different types of terminals.

[0139] In some embodiments of the present application, analyzing the first normalized transmit power to obtain the first transmit power expectation corresponding to the first cell may include the following steps:

[0140] Based on the first normalized transmit power, construct a first normal probability distribution function, where coefficients of the first normal probability distribution function include a first normal distribution mean;

[0142] The first normal distribution mean in the result of the first formula is determined as the first expected transmit power corresponding to the first cell.

[0143] For the convenience of description, the above steps are combined for explanation.

[0144] In an embodiment of the present application, after determining the first cell and obtaining the first normalized transmit power corresponding to the voice service of the terminal in the first cell, a first normal probability distribution function can be constructed based on the first normalized transmit power. The first normal probability distribution function is a discrete normal probability distribution function, which is used to describe the transmit power of the terminal in the first cell. The coefficients of the first normal probability distribution function include the first normal distribution mean.

The normal distribution mean, also known as the expectation, determines the center position of the distribution, and the normal distribution standard deviation determines the shape of the distribution. The larger the normal distribution standard deviation, the flatter the curve.

[0148] It should be noted that in the embodiment of the present application, the normal probability distribution function constructed based on the first normalized transmit power is called the first normal probability distribution function, and the normal distribution mean in the coefficient is called the first normal distribution mean.

[0149] By fitting the first normal probability distribution function using a nonlinear least squares method, a first formula result of the first normal probability distribution function can be obtained.

[0150] The nonlinear least squares method finds the best function matching data by minimizing the sum of squares of errors. The least squares method can be used to easily obtain unknown data and minimize the sum of squares of errors between the obtained data and the actual data.

[0151] One possible formula is as follows:

[0152]

[0153] Among them, y j is the jth x pThe corresponding actual probability value can be calculated according to the normalized transmit power corresponding to the voice service of the terminal. For example, the normalized transmit powers are 0.5, 0.3, 0.7, 0.5, and 0.5 respectively. The actual probability value corresponding to the normalized transmit power of 0.5 is 3 / 5, the actual probability value corresponding to the normalized transmit power of 0.3 is 1 / 5, and the actual probability value corresponding to the normalized transmit power of 0.7 is 1 / 5. j (x p ) is through the jth x p The predicted probability value.

[0154] By fitting the first normal probability distribution function by the nonlinear least square method, a first formula result can be obtained, and the first formula result includes a coefficient with the smallest error, thereby obtaining a first normal distribution mean included in the coefficient with the smallest error. The first normal distribution mean in the first formula result can be determined as the first transmit power expectation corresponding to the first cell.

[0155] By constructing a first normal probability distribution function and fitting the first normal probability distribution function through nonlinear least squares method, the coefficient with the smallest error of the first normal probability distribution function can be obtained, thereby obtaining the corresponding first normal distribution mean and accurately determining the first transmission power expectation corresponding to the first cell.

[0156] In some embodiments of the present application, analyzing the second normalized transmit power to obtain the second transmit power expectation corresponding to the second cell may include the following steps:

[0157] Based on the second normalized transmit power, construct a second normal probability distribution function, wherein coefficients of the second normal probability distribution function include a second normal distribution mean;

[0158] Fitting the second normal probability distribution function by nonlinear least squares method to obtain a second formula result of the second normal probability distribution function;

[0159] The second normal distribution mean in the result of the second formula is determined as the second expected transmit power corresponding to the second cell.

[0160] For the convenience of description, the above steps are combined for explanation.

[0161] In an embodiment of the present application, after determining the second cell and obtaining the second normalized transmit power corresponding to the voice service of the terminal in the second cell, a second normal probability distribution function can be constructed based on the second normalized transmit power. The second normal probability distribution function is a discrete normal probability distribution function, which is used to describe the transmit power of the terminal in the second cell. The coefficients of the second normal probability distribution function include the second normal distribution mean.

[0162] Normalized transmit power x corresponding to the voice service of the terminal p A normal probability distribution function f(x p )The possible formulas are as follows:

[0163]

[0164] Among them, f(x p ) includes the normal distribution mean # and the normal distribution standard deviation σ. The normal distribution mean, also known as the expectation, determines the center position of the distribution, and the normal distribution standard deviation determines the shape of the distribution. The larger the normal distribution standard deviation, the flatter the curve.

[0165] It should be noted that in the embodiment of the present application, the normal probability distribution function constructed based on the second normalized transmit power is called the second normal probability distribution function, and the normal distribution mean in the coefficient is called the second normal distribution mean.

[0166] By fitting the second normal probability distribution function using a nonlinear least squares method, a second formula result of the second normal probability distribution function can be obtained.

[0167] The nonlinear least squares method finds the best function matching data by minimizing the sum of squares of errors. The least squares method can be used to easily obtain unknown data and minimize the sum of squares of errors between the obtained data and the actual data.

[0168] One possible formula is as follows:

[0169]

[0170] Among them, y j is the jth x p The corresponding actual probability value can be calculated according to the normalized transmit power corresponding to the voice service of the terminal. For example, the normalized transmit powers are 0.5, 0.3, 0.7, 0.5, and 0.5 respectively. The actual probability value corresponding to the normalized transmit power of 0.5 is 3 / 5, the actual probability value corresponding to the normalized transmit power of 0.3 is 1 / 5, and the actual probability value corresponding to the normalized transmit power of 0.7 is 1 / 5. j (x p ) is through the jth x p The predicted probability value.

[0171] By fitting the second normal probability distribution function by the nonlinear least squares method, a second formula result can be obtained, and the second formula result includes the coefficient with the smallest error, so as to obtain the second normal distribution mean included in the coefficient with the smallest error. The second normal distribution mean in the second formula result can be determined as the second transmit power expectation corresponding to the second cell.

[0172] By constructing a second normal probability distribution function and fitting the second normal probability distribution function through nonlinear least squares method, the coefficient with the smallest error of the second normal probability distribution function can be obtained, thereby obtaining the corresponding second normal distribution mean and accurately determining the second transmission power expectation corresponding to the second cell.

[0173] In some embodiments of the present application, analyzing the first normalized transmit power to obtain the first transmit power expectation corresponding to the first cell may include the following steps:

[0174] determining different values ​​of a first normalized transmit power;

[0175] Determine the probability of occurrence of each different value;

[0176] The sum of the products of each different value and the occurrence probability of the corresponding different value is determined as the first desired transmit power corresponding to the first cell.

[0177] For example, the first normalized transmit power includes 0.7, 0.9, 0.7, 0.8, 0.6, and 0.8. The different values ​​of the first normalized transmit power are 0.6, 0.7, 0.8, and 0.9, respectively. The probability of occurrence of 0.6 is 1 / 6, the probability of occurrence of 0.7 is 2 / 6, the probability of occurrence of 0.8 is 2 / 6, and the probability of occurrence of 0.9 is 1 / 6. The first transmit power expectation = 0.6*1 / 6+0.7*2 / 6+0.8*2 / 6+0.9*1 / 6=0.75.

[0178] The above method can simply and quickly obtain the first expected transmit power corresponding to the first cell.

[0179] Correspondingly, the second normalized transmit power is analyzed to obtain the second transmit power expectation corresponding to the second cell, which can be performed with reference to the above method to simply and quickly obtain the second transmit power expectation of the second cell for the country.

[0180] In some embodiments of the present application, whether to adjust the voice coverage interoperability threshold of the first cell may be determined by the following steps:

[0181] If the first expected transmit power is greater than the second expected transmit power, determining to adjust the voice coverage interoperability threshold of the first cell;

[0182] If the first desired transmit power is less than or equal to the second desired transmit power, it is determined not to adjust the voice coverage interoperability threshold of the first cell.

[0183] As described above, the first cell meets the first condition and it is considered that the voice coverage interoperability threshold of the first cell can be adjusted. However, whether to make corresponding adjustments to the first cell needs to be determined based on the comparison result of the first transmission power expectation and the second transmission power expectation.

[0184] When the first expected transmission power is greater than the second expected transmission power, it is considered that the transmission power corresponding to the voice service of the terminal in the first cell is higher, which may affect the voice perception of the terminal. It can be determined to adjust the voice coverage interoperability threshold of the first cell.

[0185] When the first expected transmission power is less than or equal to the second expected transmission power, it is considered that the transmission power corresponding to the voice service of the terminal in the first cell is not high and will not affect the voice perception of the terminal. It can be determined that the voice coverage interoperability threshold of the first cell will not be adjusted.

[0186] According to the magnitude relationship between the first expected transmit power and the second expected transmit power, it can be determined whether the voice coverage interoperability threshold of the first cell needs to be adjusted.

[0187] In some embodiments of the present application, the adjustment operation includes:

[0188] Raising the voice coverage interoperability threshold of the first cell according to a preset range;

[0189] The maximum value of the preset range is the product of the expected difference and the maximum transmit power of the terminal, and the expected difference is the difference between the first expected transmit power and the second expected transmit power.

[0190] In the embodiment of the present application, according to the comparison result of the first transmission power expectation and the second transmission power expectation, it can be determined whether to adjust the voice coverage interoperability threshold of the first cell. For example, when the first transmission power expectation is greater than the second transmission power expectation, it is determined to adjust the voice coverage interoperability threshold of the first cell.

[0191] When it is determined to adjust the voice coverage interoperability threshold of the first cell, an adjustment operation on the first cell may be triggered, for example, an adjustment instruction may be sent to a corresponding base station through a network management system.

[0192] The adjustment operation includes increasing the voice coverage interoperability threshold of the first cell according to a preset range. The maximum value of the preset range is the product of the expected difference and the maximum transmit power of the terminal, and the expected difference is the difference between the first transmit power expectation and the second transmit power expectation. The maximum transmit power of the terminal can be the maximum value of the maximum transmit powers of different types of terminals.

[0193] That is, the voice coverage interoperability threshold is adjusted according to the difference between the first transmission power expectation corresponding to the first cell and the second transmission power expectation corresponding to the second cell. For example, if the expected difference between the first transmission power expectation and the second transmission power expectation is XdB, the voice coverage interoperability threshold of the first cell is increased by a maximum of X*26dB.

[0194] The embodiment of the present application adjusts the voice coverage interoperability threshold of the first cell instead of adjusting the voice coverage interoperability threshold of all cells in the entire network. This helps to ensure that users can improve their Internet experience when occupying high-frequency bands and that high-frequency bands can absorb as much traffic as possible.

[0195] like Figure 3 As shown, it is an example of the overall process of an embodiment of the present application. First, the cell with high uplink voice packet loss rate is identified, such as identifying the cell with high uplink voice packet loss rate based on DPI data, such as the cell with uplink voice packet loss rate greater than or equal to 2%. Then, the cell with high uplink voice packet loss rate that can be adjusted by parameters is identified, such as identification based on planning and construction plan, that is, identification based on planning and construction plan to identify whether there are other cells (generally low-frequency cells) with better coverage quality in the coverage area of ​​the cell with high uplink voice packet loss rate. Then, the transmission power of the terminal in the voice state is identified, such as collecting the transmission power information of the terminal in the voice state through the terminal manufacturer, or identifying the uplink transmission power of the terminal in the voice state based on the information reported by the terminal, and distinguishing between operators and cells, and performing power normalization. The discrete normal probability distribution function of the normalized transmission power is introduced to describe the terminal transmission power distribution in each cell, and fitting is performed based on the nonlinear least squares method, and the transmission power expectation of the corresponding cell is determined according to the fitting result. Finally, based on the difference between the expected transmit power of the cell with high uplink voice packet loss rate and the expected transmit power of the normal cell, the voice coverage interoperability threshold of the cell with high uplink voice packet loss rate is optimized.

[0196] By applying the technical solution provided in the embodiments of the present application, the voice coverage interoperability threshold can be analyzed and output in a targeted manner in combination with the actual situation of the cell, and the specific voice coverage interoperability threshold of each cell can be issued by the network management to achieve a dynamic tuning effect.

[0197] Corresponding to the above method embodiment, the embodiment of the present application further provides a voice coverage interoperability threshold adjustment device. The voice coverage interoperability threshold adjustment device described below and the voice coverage interoperability threshold adjustment method described above can refer to each other.

[0198] See also Figure 4 As shown, the voice coverage interoperability threshold adjustment device 400 includes the following modules:

[0199] A determination module 410, configured to determine a first cell that satisfies a first condition and a second cell that satisfies a second condition, wherein the first condition is used to indicate whether the voice coverage interoperability threshold can be adjusted, and the second condition is used to indicate whether the voice coverage interoperability threshold does not need to be adjusted;

[0200] A first obtaining module 420 is used to obtain a first normalized transmit power corresponding to a voice service of a terminal in a first cell, and analyze the first normalized transmit power to obtain a first transmit power expectation corresponding to the first cell;

[0201] The second obtaining module 430 is used to obtain a second normalized transmit power corresponding to the voice service of the terminal in the second cell, and analyze the second normalized transmit power to obtain a second transmit power expectation corresponding to the second cell;

[0202] The adjustment module 440 is configured to trigger an adjustment operation on the first cell when it is determined that the voice coverage interoperability threshold of the first cell is to be adjusted according to a comparison result between the first expected transmit power and the second expected transmit power.

[0203] By using the device provided in the embodiment of the present application, a first cell that meets the first condition and a second cell that meets the second condition are first determined. The first condition is used to indicate whether the voice coverage interoperability threshold can be adjusted, and the second condition is used to indicate whether the voice coverage interoperability threshold does not need to be adjusted. The first cell that meets the first condition can be considered as a cell that can adjust the voice coverage interoperability threshold, and the second cell that meets the second condition is a cell that does not need to adjust the voice coverage interoperability threshold. Then, the first normalized transmit power corresponding to the voice service of the terminal in the first cell is obtained, and the first normalized transmit power is analyzed to obtain the first transmit power expectation corresponding to the first cell. Similarly, the second normalized transmit power corresponding to the voice service of the terminal in the second cell is obtained, and the second normalized transmit power is analyzed to obtain the second transmit power expectation corresponding to the second cell. Finally, according to the comparison result of the first transmit power expectation and the second transmit power expectation, when it is determined that the voice coverage interoperability threshold of the first cell is adjusted, the adjustment operation of the first cell is triggered. By comparing the first transmission power expectation corresponding to the cell that can adjust the voice coverage interoperability threshold with the second transmission power expectation corresponding to the cell that does not need to adjust the voice coverage interoperability threshold, it is possible to accurately determine whether to adjust the voice coverage interoperability threshold of the first cell. When the judgment result is positive, the corresponding adjustment operation is triggered, which helps to improve the call perception and satisfaction of mobile voice users in the first cell.
