Technical field

The present disclosure relates to the field of mobile communication technology, and in particular, to a user scheduling method, a base station and a storage medium.

Background technique

Currently, in order to ensure the communication quality of users on rail vehicles such as light rail trains, subway trains, high-speed rail trains, maglev trains, and rail high-speed buses, mobile operators will build dedicated rail networks along the tracks. In principle, dedicated rail networks are only provided to the rails. For passengers on transportation vehicles, the network covering areas outside the track is called the public network, which provides network services to ordinary users. Due to the characteristics of wireless signals, the public network and private network areas often overlap with each other. Therefore, public network users may occupy the bandwidth resources of the private network and increase the load of the private network, which will affect the communication quality of user terminals on rail vehicles.

In order to ensure the communication quality of user terminals on rail vehicles, the private network community deploys a migration strategy for low-speed users, that is, the low-speed users residing in the private network community are moved out of the private network community. However, the migration policy takes effect in real time and does not take into account the load of the private network community. There are situations where the load of the private network community is low, but low-speed users will still be moved out. The resource utilization rate of the private network community is low, and in In the scenario of temporary parking of rail vehicles, according to the relevant relocation policy, the user terminals on the rail transit will be judged as low-speed users, and thus the private network communities will be moved out to the public network, and the public network coverage along the track Poor, the communication quality of user terminals on temporarily parked rail vehicles cannot be guaranteed.

Please refer to Figure 1. Figure 1 is a schematic flowchart of a user scheduling method provided by an embodiment of the present disclosure.

As shown in Figure 1, the user scheduling method includes steps S101 to S105.

Step S101: Obtain the first number of user terminals residing in the private network cell.

In the embodiment of the present disclosure, the private network cell can be any private network cell established by mobile operators along the track. The rail transportation vehicles can include light rail trains, subway trains, high-speed rail trains, maglev trains or rail-mounted high-speed buses. etc., taking the rail vehicle as a high-speed rail train as an example, mobile operators can establish a high-speed rail dedicated network along the high-speed railway. For example, as shown in Figure 2, the private network established by the mobile operator along the track includes private network cell 11, private network cell 12, private network cell 13, private network cell 14 and private network cell 15. This private network cell can be a private network cell. Any one of network cells 11, private network cells 12, private network cells 13, private network cells 14, and private network cells 15, that is, any private network cell in the private network, can be this private network cell.

In some embodiments, the first number of user terminals camping in the private network cell is obtained at a preset interval. The preset interval time can be set based on actual conditions, and this is not specifically limited in the embodiments of the present disclosure. For example, default The interval is 5 seconds. Therefore, the base station obtains the first number of user terminals camping in the private network cell every 5 seconds.

Step S102: Obtain the second number of target user terminals residing in the target private network cell.

In this disclosed embodiment, the target private network cell is a private network cell associated with this private network cell, and the target user terminal is a user terminal located in a rail vehicle traveling from the target private network cell to this private network cell. The target private network The cells may include private network cells adjacent to the current private network cell, or may also include private network cells not adjacent to the current private network cell. The number of target private network cells can be one or more. The number of target private network cells is related to the deployment position of this private network cell in the private network. The number of target private network cells can be set manually by the user, or it can be set based on multiple times. The actual measurement effect can also be determined based on the first number of user terminals residing in the private network community, which is not specifically limited in this embodiment of the disclosure.

For example, assuming that the target private network cell is a private network cell adjacent to the current private network cell, as shown in Figure 2, when the current private network cell is private network cell 11, the target private network of private network cell 11 The cell is the private network cell 12 adjacent to the private network cell 11. In the case where the private network cell is the private network cell 12, the target private network cell of the private network cell 12 includes the private network cell adjacent to the private network cell 12. 11 and private network community 13.

As another example, take the target private network cell including a private network cell adjacent to the current private network cell and a private network cell sub-adjacent to the current private network cell. As shown in Figure 2, the target private network of private network cell 11 The cell may include the private network cell 12 adjacent to the private network cell 11 and the next adjacent private network cell 13. The target private network cell of the private network cell 12 may include the private network cell 11 adjacent to the private network cell 12, the private network cell 13 adjacent to the private network cell 12, and the private network cell 13 adjacent to the private network cell 11. The private network cell 13 and the next adjacent private network cell 14. The target private network cell of the private network cell 13 may include the private network cell 12, the private network cell 14 and the second adjacent private network cell 11 adjacent to the private network cell 13. and private network community 15.

It can be understood that it is only an example that the target private network cell is a private network cell adjacent to the current private network cell and/or a private network cell sub-adjacent to the current private network cell. The target private network cell may also be a private network cell. The embodiments of this disclosure do not specifically limit the remaining private network cells in the network. For example, as shown in Figure 2, the target private network cell of the private network cell 11 may include a private network cell 12 adjacent to the private network cell 11, a private network cell 13 adjacent to the private network cell 11, and a private network cell 13 not adjacent to the private network cell 11. Cell 11 is adjacent or sub-adjacent to private network cell 14.

In some embodiments, when the first number of user terminals residing in the private network cell is less than the preset threshold value, the first number of user terminals residing in the private network cell is determined. The target number of target private network cells; determine the second number of target user terminals residing in each target private network cell. For example, obtain the mapping relationship table between the number of user terminals residing in the local private network cell and the number of target private network cells, query the number of target private network cells corresponding to the first number, and determine the queried number is the target quantity. The mapping relationship table includes a mapping relationship between the number of user terminals residing in the current private network cell and the number of target private network cells. The mapping relationship can be set based on the actual situation. This is not the case in the embodiments of the present disclosure. Make specific limitations.

In some embodiments, it is determined whether a user terminal with a type label of the third label resides in the target private network cell. If a user terminal with a type label of the third label resides in the target private network cell, determine the type. The moving direction of the user terminal labeled as the third label, and determine the moving direction as the traveling direction of the rail vehicle; when the private network cell is located in the traveling direction of the rail vehicle, determine the target private network of the rail vehicle The cell travels to its own private network cell, determines the number of user terminals whose type label is the third label, and determines the number of user terminals whose type label is the third label as the target user terminal residing in the target private network cell. The second number; the target private network cell transmits the second number of target user terminals residing in the target private network cell to this private network cell.

In some embodiments, when a user terminal whose type label is the third label resides in the target private network cell, and the current private network cell is not located in the traveling direction of the rail vehicle, the target private network cell does not send data to the target private network cell. Private network community transmission station The second number of target user terminals remaining in the target private network cell. When there is no user terminal with the type label of the third label camped in the target private network cell, it is determined that the second number of target user terminals camped in the target private network cell is zero.

For example, as shown in Figure 2, assume that the current private network cell is private network cell 12. The target private network cell of private network cell 12 includes private network cell 11 and private network cell 13. There is a type label resident in private network cell 11. If the user terminal is a third-label user terminal and the private network cell 12 is located in the traveling direction of the rail vehicle, determine the number of user terminals with a third-label type that resides in the private network cell 11. The private network cell 11. Pass the number of user terminals with the third label that resides in the private network cell 11 as the second number of target user terminals to the private network cell 12. Similarly, in the case where a user terminal whose type label is the third label resides in the private network cell 13, and the private network cell 12 is located in the traveling direction of the rail vehicle, determine the type of terminal resident in the private network cell 13. The number of user terminals labeled with the third label, the private network cell 13 passes the number of user terminals with the third label residing in the private network cell 11 as the second number of target user terminals to the private network cell 12 .

In some embodiments, it is determined whether the second number of target user terminals residing in the target private network cell is valid; when the second number of target user terminals residing in the target private network cell is valid, obtaining the residing The second number of target user terminals staying in the target private network cell is deleted when the second number becomes invalid.

For example, when the target user terminal switches out of the target private network cell, it is determined that the second number of target user terminals residing in the target private network cell is invalid; when the target user terminal does not switch out of the target private network cell Next, determine that the second number of target user terminals residing in the target private network cell is valid; or obtain the second number of sending times, and when the time between the sending time and the current time is greater than or equal to the preset time, Determine that the second number of target user terminals residing in the target private network cell is invalid, and when the time between the sending time and the current time is less than a preset time, determine the target user terminals residing in the target private network cell. The second number is valid, and the sending time is the time when the target private network cell sends the second number of target user terminals to this private network cell. The preset duration can be set by the user, and this is not specifically limited in the embodiments of the present disclosure.

Step S103: Predict the number of users resident in the private network cell based on the first quantity and the second quantity.

In the embodiment of the present disclosure, through the first number of user terminals residing in this private network cell and the second number of target user terminals in the private network cell associated with this private network cell, it is possible to predict the movement of rail vehicles in advance. The number of users staying in the private network community after entering the private network community can be estimated in advance the load pressure that the load of surrounding neighboring cells may bring to the private network community, and a comprehensive judgment can be made as to whether low-speed users need to be moved out of the private network community. .

In some embodiments, the Doppler frequency shift or moving speed of each user terminal residing in the private network cell is obtained; the Doppler frequency shift of the user terminal that is less than or equal to the preset Doppler frequency shift is obtained. Set the type label as the first label, or set the type label of the user terminal whose moving speed is less than or equal to the preset moving speed as the first label; set the type of user terminal whose Doppler frequency shift is greater than the preset Doppler frequency shift The label is set as the third label, or the type label of the user terminal whose moving speed is greater than the preset moving speed is set as the third label. The first label is different from the third label. The first label describes the user terminal as a low-speed user, and the third label describes the user terminal as a high-speed user. The Doppler frequency shift of the user terminal determined to be a low-speed user is less than or equal to the preset Doppler. Frequency shift, or the moving speed of the user terminal determined to be a low-speed user is less than or equal to the preset moving speed, the Doppler frequency shift of the user terminal determined to be a high-speed user is greater than the preset Doppler frequency shift, or the moving speed of the user terminal determined to be a high-speed user is greater than The preset moving speed, the preset Doppler frequency shift and the preset moving speed can be set based on actual conditions, and are not specifically limited in this embodiment of the disclosure.

In some embodiments, as shown in Figure 3, step S103 includes: sub-steps S1031 to sub-step S1033.

Sub-step S1031: Obtain the number of private network neighbor cell layers between the target private network cell and the local private network cell.

In the embodiment of the present disclosure, the number of private network neighbor cell layers between the target private network cell and this private network cell is used to represent the distance between the target private network cell and this private network cell. The higher the number of private network neighbor cell layers, the higher the number of private network neighbor cell layers. The farther the distance between the target private network cell and this private network cell is, and the lower the layer number of private network neighboring cells is, the closer the distance between the target private network cell and this private network cell is.

In the embodiment of the present disclosure, the number of adjacent cell layers of the private network may be a positive number or a negative number. For example, let k be the number of layers of private network neighboring cells, and k be a non-zero integer. When k is greater than zero, the target private network cell is the k-layer neighboring cell in the first direction of this private network cell, and in k If it is less than zero, the target private network cell is the k-layer neighbor cell in the second direction of this private network cell, and the first direction is opposite to the second direction.

For example, as shown in Figure 2, assume that the current private network cell is private network cell 13, and the target private network cell includes private network cell 12 and private network cell 14. Taking the right direction of private network cell 13 as the first direction, When the left direction of the private network cell 13 is the second direction, the number of private network neighbor cell layers between the private network cell 13 and the private network cell 12 is -1, and the number of private network neighbor cells between the private network cell 13 and the private network cell 14 is -1. The number of neighboring cells in the private network is 1. When the right direction of the private network cell 13 is the second direction and the left direction of the private network cell 13 is the first direction, the number of private network neighbor cell layers between the private network cell 13 and the private network cell 12 is 1. layer, the number of private network neighbor cell layers between private network cell 13 and private network cell 14 is -1.

In some embodiments, the cell ID of the target private network cell and the cell ID of the local private network cell are obtained; the difference between the cell ID of the target private network cell and the cell ID of the local private network cell is calculated, and the calculated The difference is determined as the number of private network neighbor cell layers between the target private network cell and this private network cell. Through the cell ID of the target private network cell and the cell ID of this private network cell, the number of private network neighbor cell layers between the target private network cell and this private network cell can be quickly determined.

For example, assuming that the difference between the cell ID of the target private network cell and the cell ID of this private network cell is 2, then the target private network cell is the layer 2 neighbor cell in the first direction of this private network cell. The number of zone layers is 2. Assume that the difference between the cell ID of the target private network cell and the cell ID of this private network cell is -2, then the target private network cell is the second layer neighbor of this private network cell in the second direction. area, the number of adjacent area layers in the private network is -2.

Sub-step S1032: Predict the gain number of user terminals stationed in the private network community after the rail vehicle enters the private network community based on the preset prediction factor, the number of private network neighbor cell layers and the second number.

In the embodiment of the present disclosure, the preset predictor may be set based on the actual situation, and the embodiment of the present disclosure does not specifically limit this. For example, if the preset predictor is greater than or equal to 0 and less than or equal to 1, the preset predictor is 0.8.

In some embodiments, the prediction coefficient of each target private network cell is calculated based on the preset predictor and the number of private network neighbor cell layers; for each target private network cell, the target users residing in the target private network cell are calculated The product between the second number of terminals and the corresponding prediction coefficient, and each calculated product is accumulated to predict the number of users staying in the private network community after the rail vehicle enters the private network community. The amount of gain for the terminal.

For example, the absolute value of the number of adjacent cell layers in the private network is taken as the power of the preset predictor, and a multi-power operation is performed on the preset predictor to obtain the prediction coefficient of the target private network cell. For example, assuming that the number of adjacent cell layers in a private network is k, and k is a non-zero integer, and i is a preset predictor, the weighting coefficient can be expressed as i ^|k| . For example, if i is 0.8 and the number of private network neighbor cell layers is 2, then the prediction coefficient of the target private network cell is 0.8 ^|2| = 0.64. For another example, if i is 0.8 and the number of private network neighbor cell layers is -2, Then the prediction coefficient of the target private network cell is 0.8 ^|-2| =0.64.

In some embodiments, when the target private network cell includes a private network cell located in the first direction of the current private network cell and a private network cell located in the second direction of the current private network cell, the formula is used Calculation is performed based on the preset predictors, the number of private network neighbor cell layers and the second number corresponding to each target private network cell to predict the number of passengers staying in the private network cell after the rail transit vehicle enters the private network cell. The number of gains of user terminals; in the target private network cell, it is located in this private network. In the case of a private network cell in the first direction of the network cell, use the formula Calculation is performed based on the preset predictors, the number of private network neighbor cell layers and the second number corresponding to each target private network cell to predict the number of passengers staying in the private network cell after the rail transit vehicle enters the private network cell. The number of gains of user terminals; when the target private network cell is a private network cell located in the second direction of the current private network cell, use the formula Calculation is performed based on the preset predictors, the number of private network neighbor cell layers and the second number corresponding to each target private network cell to predict the number of passengers staying in the private network cell after the rail transit vehicle enters the private network cell. The number of gains for the user terminal. Among them, k is the number of private network neighbor cell layers, i is the preset predictor, A _k is the second number of target user terminals residing in the target private network cell, n is the maximum number of private network neighbor cell layers, and n is A positive integer, k is a non-zero integer.

For example, suppose n is 2, and the private network cell is private network cell 13 in Figure 2. Therefore, private network cell 11, private network cell 12, private network cell 14 and private network cell 15 are the target private network cells, and The number of private network neighbor cell layers between private network community 11 and private network community 13 is -2, the number of private network neighbor cell layers between private network community 12 and private network community 13 is -1, and the number of private network neighbor cell layers between private network community 14 and private network community 13 is -1. The number of private network neighbor cell layers between private network cells 13 is 1, and the number of private network neighbor cell layers between private network cells 15 and 13 is 2. Using the formula Based on the above data, it can be predicted that after the rail vehicle enters this private network community, the gain number of user terminals stationed in this private network community is A _-2 ×i ^|-2| +A _-1 ×i ^{|-1 |} +A ₁ ×i ^|1| +A ₂ ×i ^|2| , which means that the second target user terminal residing in private network cell 11, private network cell 12, private network cell 14 and private network cell 15 The quantities are A _-2 , A _-1 , A ₁ and A ₂ respectively.

For another example, suppose n is 2, and the private network cell is the private network cell 11 in Figure 2. Therefore, the private network cell 12 and the private network cell 13 are the target private network cells, and the private network cell 12 and the private network cell 11 The number of private network neighbor cell layers between them is 1, and the number of private network neighbor cell layers between private network cell 13 and private network cell 11 is 2. Using the formula From the above data, it can be predicted that after the rail vehicle enters the private network community, the gain number of the user terminals stationed in the private network community is A ₁ ×i ^|1| +A ₂ ×i ^|2| , which shows that The second numbers of target user terminals residing in the private network cell 12 and the private network cell 13 are A ₁ and A ₂ respectively.

Sub-step S1033: Accumulate the first number and the gain number to obtain the number of user stays.

For example, the first number of user terminals residing in this private network cell is 30, the second number of target user terminals residing in the target private network cell is 50, i is 0.8, and the target private network cell is the same as this private network cell. The number of private network neighbor cell layers between the private network cells is 2, so the number of gains is 50×0.8 ^|2| = 32. Add 30 and 32 to get the number of users staying in this private network cell to be 62.

Step S104: When the number of user camps is greater than or equal to the preset threshold value, migrate the user terminal whose current type label is the first label from the private network cell to the public network cell, and set the current type label to the second label. user terminals continue to reside in this private network community.

In the embodiment of the present disclosure, the preset threshold value can be set based on the actual situation, and the embodiment of the present disclosure does not specifically limit this. The first label describes the user terminal as a low-speed user, and the second label describes the user terminal as a temporary parking user. When the number of users camping is greater than or equal to the preset threshold value, if the private network cell has user terminals whose current type label is the first label and user terminals whose current type label is the second label, the current The user terminal whose type label is the first label is migrated from the private network cell to the public network cell, and the user terminal whose current type label is the second label continues to reside in this private network community, that is, the user terminal whose current type label is the second label is not moved out. Label user terminal.

Step S105: When the number of user camps is less than the preset threshold, allow the user terminal whose current type label is the first label to continue to camp in the private network cell.

In the embodiment of the present disclosure, the relevant private network community deployment low-speed user relocation strategy is to move the low-speed users residing in the private network community out of the private network community. For the scenario of temporary parking of rail vehicles, the temporary parking of rail vehicles , will cause the private network community to determine the user terminals in the rail vehicles as low-speed users, so that the private network community will move the low-speed users out, and the communication quality of the user terminals in the temporarily parked rail vehicles cannot be guaranteed, and this disclosure In the embodiment, when it is determined that there is a temporarily parked rail vehicle in the private network community, the label of the low-speed user is adjusted to the label of the temporary parking user, and the temporary parking user continues to reside in the private network community. That is, by not moving out the temporarily parked users, it can avoid the user terminals in the rail vehicles being judged as low-speed users and causing them to move out of the private network community, thus ensuring the communication quality of the user terminals in the temporarily parked rail vehicles.

The following takes a high-speed rail train as an example of rail transportation. It is assumed that the high-speed rail private network established by mobile operators along the high-speed railway is networked with super cells, and the super cell includes 6 cell parts (Cell Portion, CP), with a station spacing of 600m. , the speed of high-speed train B is 300km/h. The user terminal in high-speed train B switches to the private network community about once every 22 seconds. It takes about 2 seconds for high-speed train B to switch to the private network community from the front of the train to the rear of the train. Each time 8 low-speed users migrate out within 2 seconds of the judgment period. The first number of user terminals residing in this private network community is 25. The preset threshold value is 35. i is 0.8 and n is 2. Assume that the high-speed rail train The user terminal in B is in the forward 2-layer neighbor cell of this private network cell, and the number of user terminals in high-speed train B is 50, that is, the second target user terminal residing in the forward 2-layer neighbor cell The quantity is 50, and the validity period of the second quantity forwarded to the layer 2 neighboring cells is 12 seconds. There are no temporary parking users in this private network community, so the number of users staying in this private network community will increase with the number of this private network community. The forward layer 2 neighbor cells, forward layer 1 neighbor cells, and surrounding public network users change in real time, causing the private network community to determine whether low-speed users need to be moved out. The result of this private network community will also change. The migration results at different times can be shown in Table 1.

Table 1

As shown in Table 1, the private network cell received the second quantity forwarded to the layer 2 neighbor cell at 9:32:50, and the second quantity was 50. The private network cell performed low-level transmission at 9:32:51. At the time of migration judgment, the number of resident users is 25+50×0.8 ^|2| = 57, which is greater than the threshold value 35. Therefore, 8 low-speed users are moved out. This private network community is at 9:32:53 and 9:32 :55, 8 low-speed users are migrated out, but no low-speed users are migrated out at time 9:32:57 and time 9:32:59. At time 9:33:03, due to the target users in the forward 2-layer neighbor area The second number of terminals is invalid, and the second number is 0. There are no low-speed users at this time, so they will not move out. From 9:33:03 to 9:33:12, the number of resident users is less than the threshold, and they will not move out. Low speed users. At time 9:33:14, the second number forwarded to the layer 1 neighbor cell is received, and the second number is 50. When the private network cell performs downshift judgment at time 9:33:14, the number of users staying is 0+50×0.8 ^|1| =40, which is greater than the threshold value, but since there are no low-speed users, there is no need to move out. From time 9:33:16 to 9:33:26, although the number of resident users is 0+50×0.8 ^|1| =40 and is greater than the threshold value, there is no need to move out because there are no low-speed users. At time 9:33:28, due to the failure of the second number of target user terminals in the forward layer 1 neighbor cell, the second number is 0. There are no low-speed users at this time and they will not move out. From time 9:33:28 to 9:33:38, due to the failure of the second number of target user terminals in the forward layer 1 neighbor cell, the second number is 0. There are no low-speed users at this time and do not move out. At time 9 :33:38, high-speed train B enters this private network community. The number of users staying is 50, which is equal to the first number, but there are no low-speed users and there is no need to move out.

The following takes a high-speed rail train as the rail transportation vehicle as an example. It is assumed that the high-speed rail private network established by mobile operators along the high-speed railway is networked in a super cell, and the super cell includes 6 cell portions (Cell Portion, CP), with a station spacing of 600m. , the speed of high-speed train B is 300km/h. The user terminal in high-speed train B switches to the private network community about once every 22 seconds. It takes about 2 seconds for high-speed train B to switch to the private network community from the front of the train to the rear of the train. Each time 8 low-speed users move out within 2 seconds of the judgment period. The number of temporary parking users staying in this private network community is 30. The preset threshold is 35. i is 0.8 and n is 2. Assume that the user terminal in high-speed train B is in the forward 2-layer neighboring cell of this private network cell, and the number of user terminals in high-speed train B is 50, that is, it resides in the forward 2 The second number of target user terminals in the layer 2 neighbor cell is 50, and the validity period of the second number forwarded to the layer 2 neighbor cell is 12 seconds. In this way, the number of users resident in this private network cell will increase with the number of users in this private network cell. The forward layer 2 neighbor cells, forward layer 1 neighbor cells, and surrounding public network users change in real time, causing the private network community to determine whether low-speed users need to be moved out. The result of this private network community will also change. The migration results at different times in the scenario of temporary parking users can be shown in Table 2.

Table 2

As shown in Table 2, the private network cell received the second quantity forwarded to the layer 2 neighbor cell at 9:32:50, and the second quantity was 50. The private network cell performed low-level transmission at 9:32:51. When making the migration judgment, the number of resident users is 30+50×0.8 ^|2| = 62, which is greater than the threshold, 35. However, there are no low-speed users at this time and there is no need to migrate out. At time 9:32:53, there are no low-speed users in this private network community and there is no need to move out. At time 9:32:55, there are 2 public network users accessing this private network community, and the number of users resident in the community is 64 greater than the door. The limit is 35, so 2 public network users are moved out. From time 9:32:57 to 9:33:01, there are no low-speed users in this private network community and do not need to move out. However, at time 9:33:03, due to the forward direction of the target user terminal in the layer 2 neighboring cell, The second quantity is invalid, the second quantity is 0, and there is no need to move out. From 9:33:03 to 9:33:12, there are no low-speed users in this private network community, and there is no need to move out. At time 9:33:14, the second number forwarded to the layer 1 neighbor cell is received, and the second number is 50. When the private network cell performs downshift judgment at time 9:33:14, the number of users staying is 30+50×0.8 ^|1| = 70, which is greater than the threshold value 35, but since there are no low-speed users, there is no need to move out. At time 9:33:16 and time 9:33:18, there are no low-speed users in this private network community and there is no need to move out. At time 9:33:20, 6 public network users access this private network community, and the number of users resident is 76 is greater than the threshold value 35, so 6 public network users are moved out. From 9:33:22 to 9:33:26, there are no low-speed users in this private network community and there is no need to move out. At time 9:33:28 , due to the failure of the second number of target user terminals in the forward layer 1 neighbor cell, the second number is 0. At this time, there are no low-speed users in this private network cell and they will not move out. At time 9:33:38, high-speed train B enters this private network community, but there are no low-speed users and does not need to move out.

The user terminal is the second label and the current type label is the user terminal of the third label. The target ratio may be a ratio set by the user in advance, or may be determined based on the ratio of the number of user terminals whose current type label is the second label and the number of user terminals whose current type label is the third label resident in the private network community. OK, this embodiment does not specifically limit this. When temporary parking users and high-speed users reside in the private network community, the temporary parking users and high-speed users occupy the bandwidth resources of the private network community in proportion, thus ensuring the communication quality of the temporary parking users and high-speed users at the same time.

In some embodiments, the number of user terminals whose current type label is the second label residing in the private network cell is determined, the number of temporary parking users is obtained, and the current type label residing in the private network cell is determined to be the third label. The number of user terminals with three tags is used to obtain the number of high-speed users; the ratio of the number of temporary parking users to the number of high-speed users is calculated, and the ratio is determined as the target ratio. For example, if the number of temporary parking users is 20 and the number of high-speed users is 30, the target ratio is 2:3. Then the temporary parking users occupy 40% of the bandwidth resources of this private network community, and the high-speed users occupy 60% of the bandwidth resources of this private network community. .
