Specifically, the number of activated users of the service carried out in each cell and the rate of the service carried out in each cell are obtained from the service data information of each cell. Further, the number of activated users of services carried out in all cells and the rate of services carried out in all cells are counted to obtain the average rate of a single user of each service set in the network to be expanded. Wherein, the services of the same type carried out in all the cells belong to the service set in the expanded network.

A specific example below illustrates the correspondence between each service set and the services carried out in all cells. For example, the network to be expanded includes three cells, namely cell 1, cell 2, and cell 3. Cell 1 includes service 1, service 2, service 3, and service 4; the services carried out in cell 2 include service 1, service 3 and service 4; the services carried out in cell 3 include service 1, service 2 and service 5. Service 1 in cell 1, cell 2, and cell 3 belongs to service set 1 in the network to be expanded, while service 2 in cell 1, cell 2, and cell 3 belongs to service set 2 in the network to be expanded, and cell 1 and cell 2 Service 3 in cell 3 belongs to service set 3 in the network to be expanded, service 4 in cell 1 and cell 2 belongs to service set 4 in the network to be expanded, and service 5 in cell 3 belongs to service set 5 in the network to be expanded. This is just an example, and those skilled in the art should know that the number of cells in the network to be expanded is not limited to the number in the above examples, and the types of services carried out in each cell are not limited to the types in the above examples.

Taking service set j as an example, the average rate of a single user of service set j Description of the acquisition process: assuming that the network to be expanded includes L cells, the rate of service j belonging to service set j carried out in all cells in the L cells and the rate of service j belonging to service set j carried out in all cells are counted Activate the number of users U _j , and then obtain the average rate of a single user of the business set j .

Single user average rate of service set j The calculation formula of is as follows:

${\stackrel{<span\; class="notranslate">\; \&OverBar;</span>}{\mathrm{<span\; class="notranslate">\; v</span>}}}_{\mathrm{<span\; class="notranslate">\; j</span>}}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; j</span>}}}<span\; class="notranslate">\; \&times;</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; L</span>}}\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; \&Element;</span>\mathrm{<span\; class="notranslate">\; A</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}{\mathrm{<span\; class="notranslate">\; v</span>}}_{\mathrm{<span\; class="notranslate">\; ij</span>}}<span\; class="notranslate">\; ;</span>$

Among them, v _ij is the rate of service j belonging to service set j carried out in cell i among the L cells, and A is the set of all cells.

103. Make statistics on the number of activated users and KPI information of the services carried out in all the cells, and obtain the average KPI information of a single user of each service set.

Specifically, the KPI information of the service carried out by each cell is obtained from the service data information of each cell. Collect statistics on the number of activated users of services carried out in all cells and the KPI information of services carried out in all cells, and obtain the average single-user rate of each service set in the network to be expanded.

Taking business set j as an example, the average KPI information of a single user of business set j The acquisition process is described: assuming that the network to be expanded includes L cells, the KPI information of the service j belonging to the service set j carried out in all the cells in the L cells and the KPI information of the service j belonging to the service set j carried out in all the cells are counted. Activate the number of users U _j to obtain the average KPI information of a single user of business set j .

Single user average KPI information of business set j The calculation formula of is as follows:

${\stackrel{<span\; class="notranslate">\; \&OverBar;</span>}{\mathrm{<span\; class="notranslate">\; K</span>}}}_{\mathrm{<span\; class="notranslate">\; j</span>}}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; j</span>}}}<span\; class="notranslate">\; \&times;</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; L</span>}}\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; \&Element;</span>\mathrm{<span\; class="notranslate">\; A</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}{\mathrm{<span\; class="notranslate">\; K</span>}}_{\mathrm{<span\; class="notranslate">\; ij</span>}}<span\; class="notranslate">\; ;</span>$

Wherein, K _ij is the KPI information of the service j belonging to the service set j carried out in the cell i among the L cells, and A is the set of all cells.

In this embodiment, the KPI information of service j belonging to service set j carried out in cell i may be the number of Packet Data Protocol (PDP) connections N _ij , correspondingly, the average KPI information of a single user of service set j is Average number of PDP connections per user . The KPI information of service j belonging to service set j carried out in cell i can be the PDP connection delay D _ij , correspondingly, the single-user average KPI information of service set j is the single-user average PDP connection delay . If the KPI information of service j belonging to service set j carried out in cell i includes the number of PDP connections N _ij and PDP connection delay D _ij , correspondingly, the average KPI information of a single user of service set j includes the average number of PDP connections of a single user and single-user average PDP connection delay .

Correspondingly, the average number of PDP connections of a single user of service set j The calculation formula of is as follows:

${\stackrel{<span\; class="notranslate">\; \&OverBar;</span>}{\mathrm{<span\; class="notranslate">\; N</span>}}}_{\mathrm{<span\; class="notranslate">\; j</span>}}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; j</span>}}}<span\; class="notranslate">\; \&times;</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; L</span>}}\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; \&Element;</span>\mathrm{<span\; class="notranslate">\; A</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}{\mathrm{<span\; class="notranslate">\; N</span>}}_{\mathrm{<span\; class="notranslate">\; ij</span>}}$

Single-user average PDP connection delay of service set j The calculation formula of is as follows:

${\stackrel{<span\; class="notranslate">\; \&OverBar;</span>}{\mathrm{<span\; class="notranslate">\; D.</span>}}}_{\mathrm{<span\; class="notranslate">\; j</span>}}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; j</span>}}}<span\; class="notranslate">\; \&times;</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; L</span>}}\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; \&Element;</span>\mathrm{<span\; class="notranslate">\; A</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}{\mathrm{<span\; class="notranslate">\; D.</span>}}_{\mathrm{<span\; class="notranslate">\; ij</span>}}$

104. Obtain the target rate of each service set according to the single-user average rate and the single-user average KPI information of each service set.

Specifically, for each service set in each service set in the cell to be expanded, the single-user average rate of the service set is used as the comparison threshold of the service set. Further, the comparison threshold of the service set is compared with the rate of services belonging to the service set carried out in each cell to obtain the first cell. Wherein, the absolute difference between the rates of the services belonging to the service set carried out in the first cell and the average rate of a single user of the service set is the smallest. That is to say, the rate of the services belonging to the service set carried out in the first cell is closest to the average rate of a single user of the service set. Then, the KPI information of the services belonging to the service set carried out in the first cell is compared with the single-user average KPI information of the service set. If the KPI information of the service belonging to the service set carried out in the first cell is smaller than the single-user average KPI information of the service set, the single-user average rate of the service set is taken as the target rate of the service set. Wherein, the target rate of the service set is a single user rate that meets the user's basic experience requirements.

Further, for each service set in each service set in the cell to be expanded, if the KPI information of the business belonging to the service set carried out in the first cell is greater than or equal to the single-user average KPI information of the service set, adjust the KPI information of the service set The single-user average rate, the adjusted single-user average rate of the service set is used as the comparison threshold of the service set, and then the comparison threshold of the service set is compared with the rate of the business belonging to the service set carried out in each cell, to re-acquire the first cell, and compare the KPI information of the business belonging to the service set carried out in the first cell with the average KPI information of a single user of the service set, and if the KPI information of the first service in the first cell is less than The single-user average KPI information of the service set, and the adjusted single-user average rate of the service set as the target rate of the service set.

Taking service set j as an example, the target rate of each service set is obtained according to the average number of PDP connections of a single user and the average rate of a single user, or the average PDP connection delay of a single user and the average rate of a single user of each service set are obtained. The process of the target rate of each business set is explained:

Specifically, the single-user average rate of service set j As the comparison threshold of the service set j, compare the rate v _ij of the service j belonging to the service set j carried out in all the cells with the comparison threshold of the service set j, from all the cells in the first cell, wherein, in the first cell The absolute difference between the rate v _1j of service j and the comparison threshold of service set j is the smallest. Further, combine the KPI information K _1j of service j in the first cell with the single-user average KPI information of service set j For comparison, if the KPI information K _1j of service j in the first cell is less than the single-user average KPI information of service set j , the single-user average rate of the service set j as the target rate of service set j. Wherein, the service set j may be any service set in all service sets in the network to be expanded.

If the KPI information K _1j of service j in the first cell is greater than or equal to the single-user average KPI information of service set j , to adjust the average rate of a single user of service set j , and then the adjusted single-user average rate of service set j As the comparison threshold of service set j, reacquire the first cell and combine the KPI information K _1j of service j in the first cell with the single-user average KPI information of service set j Steps to compare. If the KPI information K _1j of service j in the first cell is less than the single-user average KPI information of service j , the adjusted single-user average rate of the service set j as the target rate of service set j. In this example, the KPI information K _1j of service j in the first cell is the number of PDP connections or PDP connection delay, correspondingly, the average KPI information of a single user of service set j It is the average number of PDP connections of a single user or the average PDP connection delay of a single user.

Taking service set j as an example, the process of obtaining the target rate of each service set is described according to the average number of PDP connections per user, the average PDP connection delay and the average speed of a single user in each service set:

Specifically, the single-user average rate of service set j As the comparison threshold of service set j, the rate of service j belonging to service set j carried out in all cells is compared with the comparison threshold of service set j, and from all the cells in the first cell, the service j in the first cell The absolute difference between the rate v _1j of the service set j and the comparison threshold of the service set j is the smallest.

Further, combine the KPI information _K1j of the service j belonging to the service set j carried out in the first cell with the single-user average KPI information of the service set j For comparison, the number of PDP connections N _1j and PDP connection delay D _1j of the service j belonging to the service set j carried out in the first cell are respectively compared with the average number of PDP connections of a single user of the service set j and single-user average PDP connection delay Compare.

If the number of PDP connections N _1j of the service j belonging to the service set j carried out in the first cell is less than the average number of PDP connections of a single user of the service set j , and the PDP connection delay D _1j of the service j belonging to the service set j carried out in the first cell is less than the single-user average PDP connection delay of the service set j ,Right now and The single-user average rate of the service set j can be used as the target rate of the service set.

In practice, if the first cell satisfies and It shows that the obtained current target rate of service set j has exceeded the requirement of basic user experience for single-user service rate. If the expansion index is obtained based on the current target rate of service set j, it is difficult to accurately measure the cells that need to be expanded. In order to better expand the capacity of cells in the network, to achieve a balance between network construction costs and user experience. Optionally, after comparing the first cell to satisfy and , adjust the current target rate of the service set j according to the preset adjustment factor, and use the adjusted current target rate of the service set j as the comparison threshold, then select the first cell from all the cells and perform subsequent operations until the selected The number of PDP connections N _1j of the service j belonging to the service set j carried out in the first cell is greater than or equal to the average number of PDP connections of a single user of the service set j And the PDP connection delay D _1j of the service j belonging to the service set j carried out in the first cell is less than the single-user average PDP connection delay of the service set j Or the number of PDP connections N _1j of the service j belonging to the service set j carried out in the first cell is less than the average number of PDP connections of a single user of the service set j And the PDP connection delay D _1j of the service j belonging to the service set j carried out in the first cell is greater than or equal to the single-user average PDP connection delay of the service set j , that is, the first cell satisfies and or the first cell satisfies and Then stop reacquiring the first cell, and use the adjusted current target rate of the service set j corresponding to the first cell as the target rate of the service set j.

If the number of PDP connections N _1j of the service j belonging to the service set j carried out in the first cell is greater than or equal to the average number of PDP connections of a single user of the service set j And the PDP connection delay D _1j of the service set carried out in the first cell is greater than or equal to the single-user average PDP connection delay of the service set j which is and It shows that the obtained current target rate of the service set j cannot meet the requirement of the user's basic experience for the single-user service rate. According to the preset adjustment factor, the average rate of a single user for service set j adjusted and the adjusted average rate per user Set as the comparison threshold of the service set, re-execute the acquisition of the first cell and subsequent operations until the acquired first cell satisfies and or the first cell satisfies and Then stop reacquiring the first cell, and use the adjusted current target rate of the service set j corresponding to the first cell as the target rate of the service set j.

If the comparison shows that the first cell satisfies and or the first cell satisfies and The single-user average rate of service set j can be as the target rate of service set j.

Preferably, the cell set A can be divided into two sets A ₁ and A ₂ according to the average rate of a single user of the service set, where In the following, the service set j is taken as an example for description. Select the _first cell from all the cells in the set A1 and denote it as cell t. Combine KPI information K _tj of service j carried out in cell t with single-user average KPI information of service set j Among them, KPI information K _tj of service j carried out in cell t includes the number of PDP connections N _tj and PDP connection delay D _tj , and the average KPI information of a single user of service set j includes the average number of PDP connections of a single user and single-user average PDP connection delay

If cell t in set A ₁ satisfies and The average single-user rate of the service set j can be as the target rate of the service set j.

In practice, if cell t satisfies and It shows that the obtained current target rate of service set j has exceeded the requirement of basic user experience for single-user service rate. If the expansion index is obtained based on the current target rate of service set j, it is difficult to accurately measure the cells that need to be expanded. In order to better expand the capacity of cells in the network, to achieve a balance between network construction costs and user experience. Optionally, after comparing cell t to satisfy and When , the current target rate of service set j is adjusted according to the preset adjustment factor. For example, to adjust by a factor of 5 get Then As the comparison threshold of service set j, the first cell is selected from all the cells in set _A2 as cell n, and the number of PDP connections N _nj and PDP connection delay D _nj of service j carried out in cell n are compared with user Average number of PDP connections and single-user average PDP connection delay Compare. if and Continue to adjust with 5 as the adjustment factor get And follow-up operations, until the first cell selected from the set A2 is _denoted as cell m, cell m satisfies and Or cell m satisfies and Then stop reacquiring the first cell, and adjust the current target rate of the service set j corresponding to the cell m The single-user service rate that can satisfy the user's basic experience, where Δ is the adjustment factor of 5 The number of adjustments.

If cell t in set A ₁ satisfies and Describe the average rate of a single user of service set j It cannot meet the requirements of the user's basic experience for the single-user service rate. According to the preset adjustment factor, the average rate of a single user for service set j Make adjustments. For example, to adjust by a factor of 5 get Then As the comparison threshold of service set j, the _first cell is selected from all the cells in set A1 and recorded as cell g, and the number of PDP connections _Ngj and PDP connection delay _Dgj of service j carried out in cell g are compared with the user Average number of PDP connections and single-user average PDP connection delay Compare. if and Continue to adjust with 5 as the adjustment factor get And follow-up operations, until the first cell obtained from the set A ₁ is denoted as cell q, and cell q satisfies and Or cell q satisfies and Then stop reselecting the first cell from the set A ₁ , and set the current cell q corresponding to As the target rate that satisfies the user's basic experience, where λ represents the adjustment factor of 5 to The number of times adjustments were made. Based on the method and process for obtaining the target rate of the service set j above, the target rate of other service sets meeting the basic user experience requirements can also be obtained.

If cell t in set A ₁ satisfies and Or cell t satisfies and The single-user average rate of service set j can be as the target rate of service set j.

105. Acquire the expansion index of the target cell according to the target rate of each service set and the service composition information of the target cell; wherein the target cell is any cell in the network to be expanded.

Specifically, the total service flow of the target cell and the service flow of each service carried out in the target cell are extracted from the service composition information of the target cell. Optionally, the service configuration information of the target cell may be carried in the service data information of the target cell. Further, according to the total service flow of the target cell and the service flow of each service carried out in the target cell, the composition ratio of each service carried out in the target cell may be obtained.

For example, there are M types of services in the target cell. Taking service a among the M types of services as an example, the service flow of service a is s _a , where, a∈M, the total service flow of the target cell is s.

The composition ratio p _a of business a is:

Wherein, a=1, 2,...M, p ₁ +p ₂ +...+p _M =1.

Further, according to the target rate of each service set obtained in step 104, the proportion of each service in the target cell, and the number of activated users of each service in the target cell, the expansion index of the target cell is obtained statistically.

Assuming that M types of services are launched in the target cell, the formula for statistically obtaining the expansion index of the target cell is:

$\mathrm{<span\; class="notranslate">\; B</span>}<span\; class="notranslate">\; =</span>\underset{\mathrm{<span\; class="notranslate">\; a</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}}{\overset{\mathrm{<span\; class="notranslate">\; m</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}}{\mathrm{<span\; class="notranslate">\; p</span>}}_{\mathrm{<span\; class="notranslate">\; a</span>}}<span\; class="notranslate">\; *</span>{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; a</span>}}<span\; class="notranslate">\; *</span>{\mathrm{<span\; class="notranslate">\; v</span>}}_{\mathrm{<span\; class="notranslate">\; a</span>}}<span\; class="notranslate">\; ,</span>$

a=1,2,...M, p ₁ +p ₂ +...+p _M =1.

Among them, B represents the expansion index of the target cell, p _a represents the composition ratio of service a, u _a represents the number of activated users of service a, and v _a represents the target rate of service set a.

106. Expand the capacity of the target cell according to the capacity expansion index of the target cell.

Specifically, the observation time of the target cell is acquired, and the average traffic rate of the target cell is acquired according to the total service flow of the target cell acquired in step 105 and the observation time of the target cell.

The specific formula is:

v=S/T;

In this embodiment, an optional implementation structure of the second acquiring module 24 includes: a setting unit 241 , a first comparing unit 242 and a first acquiring unit 243 .

The setting unit 241, for each service set in each service set in the cell to be expanded, takes the single-user average rate of the service set as the comparison threshold of the service set. The setting unit 241 is connected to the first comparison unit 242, and compares the rate of the service belonging to the service set carried out in each cell with the comparison threshold of the service set to obtain the first cell. Wherein, the absolute difference between the rates of the services belonging to the service set carried out in the first cell and the average rate of a single user of the service set is the smallest. That is to say, the rate of the services belonging to the service set carried out in the first cell is closest to the average rate of a single user of the service set. Further, the first comparing unit 242 compares the KPI information of the services belonging to the service set carried out in the first cell with the single-user average KPI information of the service set. The first comparison unit 242 is connected with the first acquisition unit 243, if the KPI information of the business belonging to the service set carried out in the first cell is less than the average KPI information of a single user of the service set, the first acquisition unit 243 will use the single user of the service set The average rate is used as the target rate of the service set. Wherein, the target rate of the service set is a single user rate that meets the user's basic experience requirements.

Further, the second acquisition module 24 may also include an adjustment unit 244 . For each service set in each service set in the community to be expanded, if the first comparison unit 242 compares the KPI information of the business belonging to the service set carried out in the first community is greater than or equal to the single-user average KPI information of the service set, adjust Unit 244 will adjust the single-user average rate of the service set according to the preset adjustment factor, and then the setting unit 241 will use the adjusted single-user average rate of the service set as the comparison threshold of the service set, and then first The comparison unit 242 compares the rate of the service belonging to the service set carried out in each cell with the comparison threshold of the service set to reacquire the first cell, and compares the rate of the service belonging to the service set carried out in the first cell The operation of comparing the KPI information with the average KPI information of a single user of the service set, until the obtained KPI information of the service belonging to the service set carried out in the first cell is less than the average KPI information of a single user of the service set, the first acquisition unit 243 takes the adjusted single-user average rate of the service set corresponding to the first cell as the target rate of the service set.

Taking service set j as an example, the target rate of each service set is obtained according to the average number of PDP connections of a single user and the average rate of a single user, or the average PDP connection delay of a single user and the average rate of a single user of each service set are obtained. The process of the target rate of each business set is explained:

Specifically, the setting unit 241 sets the single-user average rate of service set j As the comparison threshold of the service set j, the first comparison unit 242 compares the rate v _ij of the service j belonging to the service set j carried out in all the cells with the comparison threshold of the service set j, from the first cell in all the cells, wherein, The absolute difference between the rate v _1j of the service j in the first cell and the comparison threshold of the service set j is the smallest.

Further, the first comparison unit 242 compares the KPI information K _1j of service j in the first cell with the single-user average KPI information of service set j For comparison, if the KPI information K _1j of service j in the first cell is less than the single-user average KPI information of service set j The first acquisition unit 243 takes the single-user average rate of the service set j as the target rate of service set j. Wherein, the service set j may be any service set in all service sets in the network to be expanded.

If the first comparison unit 242 compares that the KPI information K _1j of service j in the first cell is greater than or equal to the single-user average KPI information of service set j The adjustment unit 244 adjusts the single-user average rate of the service set j Then the setting unit 241 sets the adjusted single-user average rate of the service set j As the comparison threshold of the service set j, the first comparison unit 242 reacquires the first cell. The first comparison unit 242 re-executes the comparison of the KPI information K _1j of service j in the first cell with the single-user average KPI information of service j. Steps to compare. Until the KPI information K _1j of service j in the first cell acquired by the first comparison unit 242 is smaller than the single-user average KPI information of service set j The first obtaining unit 243 adjusts the single-user average rate of the service set j corresponding to the first cell as the target rate of service set j. In this example, the KPI information K _1j of service j in the first cell is the number of PDP connections or PDP connection delay, correspondingly, the average KPI information of a single user of service set j It is the average number of PDP connections of a single user or the average PDP connection delay of a single user.

Taking service set j as an example, the process of obtaining the target rate of each service set is described according to the average number of PDP connections per user, the average PDP connection delay and the average speed of a single user in each service set:

Specifically, the setting unit 241 sets the single-user average rate of service set j As the comparison threshold of service set j, the rate of service j belonging to service set j carried out in all cells is compared with the comparison threshold of service set j, and from all the cells in the first cell, the service j in the first cell The absolute difference between the rate v _1j of the service set j and the comparison threshold of the service set j is the smallest.

Further, the first comparison unit 242 compares the KPI information _K1j of the service j belonging to the service set j carried out in the first cell with the single-user average KPI information of the service set j For comparison, the number of PDP connections N _1j and PDP connection delay D _1j of the service j belonging to the service set j carried out in the first cell are respectively compared with the average number of PDP connections of a single user of the service set j and single-user average PDP connection delay Compare.

If the first comparison unit 242 compares that the first cell satisfies and When , the single-user average rate of service set j can be as the target rate of service set j.

In practice, if the comparison shows that the first cell satisfies and It shows that the obtained current target rate of service set j has exceeded the requirement of basic user experience for single-user service rate. If the expansion index is obtained based on the current target rate of service set j, it is difficult to accurately measure the cells that need to be expanded. In order to better expand the capacity of cells in the network, to achieve a balance between network construction costs and user experience. Optionally, after comparing the first cell to satisfy and , the adjustment unit 244 adjusts the current target rate of the service set j according to the preset adjustment factor, and the setting unit 241 uses the adjusted current target rate of the service set j as the comparison threshold, and then the first comparison unit 242 starts again from all cells Selecting the first cell and subsequent operations until the first cell selected by the first comparison unit 242 satisfies and or the first cell satisfies and Then stop reacquiring the first cell. The first acquiring unit 243 takes the adjusted current target rate of the service set j corresponding to the first cell as the target rate of the service set j.

If the first comparison unit 242 compares that the first cell satisfies and Describe the average rate of a single user of the obtained service set j It cannot meet the requirements of the user's basic experience for the single-user service rate. The adjustment unit 244 adjusts the average rate of a single user of the service set j according to the preset adjustment factor adjustment, the setting unit 241 will adjust the average rate of a single user Set as the comparison threshold of business set j. The first comparison unit 242 reselects the first cell and performs subsequent operations until the acquired first cell satisfies and or the first cell satisfies and Then stop reacquiring the first cell. The first acquiring unit 243 takes the adjusted single-user average rate of the service set j corresponding to the first cell as the target rate of the service set j.

If the first comparison unit 242 compares that the first cell satisfies and or the first cell satisfies and The first acquisition unit 243 can take the single-user average rate of the service set j as the target rate of service set j.

Preferably, the setting unit 241 can divide the cell set A into two sets A ₁ and A ₂ according to the average rate of a single user of the service set, where In the following, the service set j is taken as an example for description. The first comparing unit 242 selects the _first cell from all the cells in the set A1 and marks it as cell t. And the first comparison unit 242 compares the KPI information K tj of the j service j belonging to the service set carried out in the cell t with the single-user average KPI information K _tj of the service set j Among them, KPI information K _tj of service j carried out in cell t includes the number of PDP connections N _tj and PDP connection delay D _tj , and the average KPI information of a single user of service set j includes the average number of PDP connections of a single user and single-user average PDP connection delay

If the first comparison unit 242 compares that the cell _t in the set A1 satisfies and The first acquisition unit 243 can use the single-user average rate of the service set j as the target rate of the service set j.

In practice, if the first comparison unit 242 compares that the cell _t in the set A1 satisfies and It shows that the obtained current target rate of service set j has exceeded the requirement of basic user experience for single-user service rate. If the expansion index is obtained based on the current target rate of service set j, it is difficult to accurately measure the cells that need to be expanded. In order to better expand the capacity of cells in the network, to achieve a balance between network construction costs and user experience. Optionally, after comparing cell t to satisfy and When , the adjustment unit 244 can adjust the average rate of a single user of the service set j according to the preset adjustment factor For example, to adjust by a factor of 5 get followed by As the comparison threshold of the service set j, the first comparison unit 242 selects the first cell from all the cells in the set A2 and _marks it as cell n, and calculates the number of PDP connections _N and the PDP connection time delay of the service j carried out in the cell n D _nj and the average number of PDP connections of users respectively and single-user average PDP connection delay Compare. if and The adjustment unit 244 continues to perform adjustment with an adjustment factor of 5 get And subsequent operations, until the first cell selected by the first comparison unit 242 from the set A2 is _denoted as cell m, cell m satisfies and Or cell m satisfies and Then the first comparing unit 242 stops reacquiring the first cell. The first acquisition unit 243 adjusts the single-user average rate of the service set j corresponding to the cell m as the target rate of service set j. Among them, Δ is the adjustment factor pair with 5 The number of adjustments. The target rate can meet the single-user service rate that the user basically experiences.

If the first comparison unit 242 compares that the cell _t in the set A1 satisfies and Describe the average rate of a single user of service set j It cannot meet the requirements of the user's basic experience for the single-user service rate. The adjustment unit 244 adjusts the average rate of a single user of the service set j according to the preset adjustment factor Make adjustments. For example, to adjust by a factor of 5 get Then the setting unit 241 will As the comparison threshold of business set j. The first comparison unit 242 can select the _first cell from all the cells in the set A1 and record it as cell g, and compare the number of PDP connections N _gj and the PDP connection time delay D _gj of the service j carried out in the cell g with the average PDP of the user respectively. Connections and single-user average PDP connection delay Compare. If the cell g satisfies the comparison and The adjustment unit 244 continues to adjust with 5 as the adjustment factor get And perform subsequent operations until the _first cell obtained by the first comparing unit 242 from the set A1 is denoted as cell q, and cell q satisfies and Or cell q satisfies and Then stop reselecting the _first cell from the set A1. The first obtaining unit 243 obtains the current as the target rate of service set j. Among them, λ represents the adjustment factor of 5 to The number of times adjustments were made.

If the first comparison unit 242 compares that the cell _t in the set A1 satisfies and Or cell t satisfies and The single-user average rate of service set j can be as the target rate of service set j.

Based on the above method and process for obtaining the target rate of the service set j, correspondingly, the target rate of other service sets meeting the user's basic experience requirements is obtained.
