Description

Policy control method, device, equipment and storage medium

Technical Field

The present application relates to the field of wireless communications, and in particular, to a policy control method, apparatus and device.

Background

At present, after a User Equipment (UE) accesses a wireless network, the UE reports location information to a core network device through a radio access network device such as a base station. And the core network equipment matches the service area where the UE is located according to the position information reported by the UE, and further matches the control strategy of the service area where the UE is located. The control policy may include a Quality Of Service (QOS) rule and a Charging Rule (CR). For example, if the UE is located in a preset service area, the core network device allocates a larger bandwidth to the UE and executes a charging rule with a lower price. Otherwise, the core network device allocates a smaller bandwidth to the UE and executes a charging rule with a higher price.

In practical application, daily maintenance of the radio access network, such as increasing or decreasing the number of base stations and cells, and modifying the parameters of the base stations and the cells, is usually performed on the radio access network side, and the core network device cannot synchronize the configuration information of the radio access network in time. Thus, when the UE accesses the wireless network in the service area where the radio access network parameters have been updated, the core network device may not be able to match the corresponding service area or the wrong service area according to the location information reported by the UE, and further, the UE is configured with the wrong QOS rule and charging rule, that is, the UE is subjected to the wrong flow control and charging.

In order to achieve the above purpose, the embodiments of the present application provide the following technical solutions:

in a first aspect, a policy control method is provided. The method can comprise the following steps: acquiring a user event record (EDR) reported by at least one User Equipment (UE); the EDR carries the UE identification, the reporting time and the position of the UE. Then, determining a target area according to the EDR reported by at least one UE; wherein the target area satisfies the following condition: the number of the target UEs located in the target area is larger than a preset number threshold; the target UE satisfies any one of the following conditions: the specified service is opened, the staying time in the cells contained in the target area is longer than a first time threshold, switching is carried out in at least two cells contained in the target area, the staying time in each cell is shorter than a second time threshold, and the cells contained in the target area stay in the preset time period. And then configuring a target control strategy for the target UE located in the target area.

The embodiment of the application provides a policy control method, which can count the number of target UEs which are located in the same region and meet preset conditions according to an EDR reported by at least one UE; if the number of the target UE is larger than the preset threshold value, the same area is determined as the target area, and a target control strategy is configured for the target UE in the target area, so that the problem that the strategy control equipment cannot be matched with a corresponding service area or a wrong service area according to the position reported by the UE under the condition that the number and the configuration parameters of base stations and cells in a wireless access network are changed but cannot be synchronized to the strategy control equipment in time can be solved, the wrong QOS rule and the wrong charging rule are configured for the UE in the area, the actual distribution condition of the target UE in the target area can be determined in real time, the corresponding QOS rule and the corresponding charging rule are distributed for the target UE, and the accuracy and the efficiency of strategy control can be improved.

In one possible design approach, the target UE includes a UE that has a specified service enabled and has a duration of stay within a cell included in the target area greater than a first duration threshold. Correspondingly, determining the target area according to the EDR reported by at least one UE may include: and determining a cell where the UE is located according to the position of the UE, and determining a first proportion of target UE contained in the cell where the UE is located to all the UE in the cell where the UE is located. If the first ratio is greater than the first ratio threshold, it may be determined that the cell in which the UE is located is the target area.

In a possible design method, after determining that a cell in which the UE is located is a target area if the first ratio is greater than the first ratio threshold, the method may further include: after the preset time length, determining a second proportion of target UE contained in the cell where the UE is located to all UE in the cell where the UE is located; and if the second ratio is larger than the second ratio threshold, determining that the cell in which the UE is located is the target area.

In frequent switching areas such as high-speed rails and subways, a large amount of network resources are occupied by switching signaling of the UE, so that the available network resources cannot meet the communication requirements of the UE. Therefore, in order to ensure that the communication of the handover frequent region is smooth, a control strategy with higher priority can be configured for the handover frequent region. In a possible design method, determining a target area according to an EDR reported by at least one UE may include: determining a cell where the UE is located according to the position of the UE; and if the UE is switched between the at least two cells and the stay time of the UE in each cell of the at least two cells is smaller than the second time threshold, determining an area formed by the at least two cells as a target area. Wherein the priority of the target control strategy is greater than the first priority threshold.

In a mall, a station, and other dense areas, there may be a situation where a large number of UEs need to access a wireless network, so that the available network resources cannot meet the communication requirements of a large number of UEs. Therefore, in order to ensure that the communication of the personnel-dense area is smooth, a control strategy with higher priority can be configured for the personnel-dense area. In a possible design method, determining a target area according to an EDR reported by at least one UE may include: determining a cell where the UE is located according to the position of the UE; determining the number of the UE staying in the same target cell within a preset time period according to the reporting time of the EDR record; and if the number is larger than the preset number threshold, determining the target cell as the target area.

The determining module is used for determining a target area according to the EDR reported by at least one UE; wherein the target area satisfies the following condition: the number of the target UEs located in the target area is larger than a preset number threshold; the target UE satisfies any one of the following conditions: the specified service is opened, the staying time in the cells contained in the target area is longer than a first time threshold, switching is carried out in at least two cells contained in the target area, the staying time in each cell is shorter than a second time threshold, and the cells contained in the target area stay in the preset time period. A configuration module, configured to configure a target control policy for a target UE located in a target area. The apparatus may also include a storage module to store instructions and data.

In one possible design, the target UE includes a UE that has a specified service turned on and has a duration of stay within a cell included in the target area greater than a first duration threshold. Correspondingly, the determining module is further configured to determine, according to the location of the UE, a cell in which the UE is located, and a first ratio of the target UE included in the cell in which the UE is located to all UEs in the cell in which the UE is located. In addition, the determining module is further configured to determine that the cell in which the UE is located is the target area if the first ratio is greater than the first ratio threshold.

Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.

Fig. 1 shows an architecture diagram of a wireless network to which existing policy control is applied. As shown in fig. 1, the wireless network may include a UE, a radio access network device, a Policy and Charging Enforcement Function (PCEF) device, and a Policy and Charging Rules Function (PCRF) device. The access network device is mainly used for realizing wireless physical layer functions, resource scheduling and wireless resource management, wireless access control and mobility management functions. The PCRF equipment is mainly used for distributing control strategies for the UE according to the position of the UE. The control strategy mainly comprises a QOS rule and a charging rule of the UE. The PCEF device is mainly configured to control QOS and charging of the UE according to the control policy. The PCRF equipment and the PCEF equipment are core network equipment.

Illustratively, the UE shown in fig. 1 may be any UE such as a Mobile phone, a wearable device, an Augmented Reality (AR)/Virtual Reality (VR) device, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and the like, and of course, in the following embodiments, the specific form of the UE is not limited at all.

Specifically, as shown in fig. 2, the step of assigning and executing the preset control policy to the UE may generally include S201-S213:

s201, the UE reports the position of the UE to the PCEF equipment. For example, the UE may send an internet protocol Connectivity Access Network (IP-CAN) session establishment request message to the PCEF device through the radio Access Network device. Wherein, the IP-CAN session establishment request message carries the location of the UE. The location of the UE may include a Cell Global Identity (CGI), a Service Area Identity (SAI), a Routing Area Identity (RAI), a Tracking Area Identity (TAI), and the like.

S202, the PCEF device forwards the location of the UE to the PCRF device. For example, the PCEF device may send a Credit Control Request-Initial (CCR-I) message to the PCRF device. Wherein, the CCR-I message carries the position of the UE.

S203, the PCRF equipment judges whether the position of the UE is matched with a local preset service area of the PCRF equipment or not, and distributes a control strategy for the UE according to a matching result. For example, the PCRF device matches a control policy of a service area where the UE is located according to the location of the UE, where the control policy may include a QOS rule and a charging rule.

It should be noted that the preset service areas may include at least two groups of service areas with different priorities, and each group of service areas may include at least one service area. For example, the preset service areas may include three types of service areas having different priorities: a service area of the UE registration place, a service area that is nationally roamable outside the UE registration place, and a service area that is abroad roamable. The service area where the UE is registered has the highest priority, and a control policy with the highest QOS and the lowest price may be allocated to the UE. Accordingly, the service area that can roam abroad has the lowest priority, and a control policy with the lowest QOS and the highest price needs to be allocated to the UE.

And S204, the PCRF equipment sends the control policy to the PCEF equipment. For example, the PCRF device sends a Credit Control Answer-Initial (CCA-I) message to the PCEF device. Wherein the CCA-I message carries the control strategy.

S205, the PCEF device receives and installs the control policy.

S206, the PCEF device notifies the UE that the control policy is in effect. For example, the PCEF device sends an IP-CAN session setup response message to the UE.

S207, the UE initiates the service. Such as making a phone call and surfing the internet.

And S208, the PCEF equipment controls the QOS of the UE and charges the UE according to the control strategy.

S209, of course, if the location of the UE is updated, the UE reports the updated location of the UE to the PCEF device. For example, the UE may send a CCR update request message to the PCEF device through the radio access network device. Wherein, the CCR update request message carries the updated location of the UE.

S210, the PCEF device forwards the updated location of the UE to the PCRF device.

S211, if the PCRF device determines that the updated location of the UE is not matched with the locally preset service area information of the PCRF device, the PCRF device allocates a new control policy for the UE. For example, the PCRF device matches the QOS rule and the charging rule of the service area where the UE is located according to the updated location of the UE, and generates a new control policy.

S212, the PCRF device sends the new control policy to the PCEF device. For example, the PCRF device may send a CCA update response message to the PCEF device. And the CCA updating response message carries a new control strategy.

S213, the PCEF equipment receives the new control strategy, deletes the original control strategy and installs the new control strategy.

In summary, in the existing UE control policy, a preset control policy is determined to be allocated and executed for the UE by determining a matching result between the location of the UE reported by the UE and a preset service area in the PCRF device. However, when the service area configuration preset in the PCRF device is inconsistent with the base station configuration in the radio access network, for example, the base station or cell configuration in the preset service area is updated but not synchronized to the PCRF device in time, the PCRF device cannot match the location of the UE with the preset service area, and allocate and execute a correct control policy for the UE. Moreover, the existing UE control strategy does not have the capability of identifying a specific area in real time, such as an area along a subway or a high-speed rail where cell switching is frequent, and a high-load area such as a shopping mall, a station, and a school, and adjusting the specific area control strategy in real time according to the actual situation of the specific area. Therefore, the existing UE control strategy has the problem of poor accuracy and efficiency of the policy control.

The policy control method and the policy control device provided by the embodiment of the application can automatically identify and monitor the number of the UE in each subordinate cell, and adjust the control policy of the subordinate cell in real time when the number of the target UE in part or all of the subordinate cells meets the preset number threshold, so that the accuracy and efficiency of distributing and executing the control policy can be improved.

Fig. 3 is a schematic diagram of a wireless network to which the policy control method provided in the embodiment of the present application is applied.

As shown in fig. 3, the wireless network further includes a Policy Control Platform (POP) as compared to the wireless network shown in fig. 1. The POP is mainly used for executing the policy control method provided by the embodiment of the application. In addition, the POP may also be connected to a service Operation Support System (BOSS) and configured to receive a UE list (a subscriber corresponding to a specified service) that is sent by the BOSS and has activated the specified service.

It should be noted that the POP may be implemented as a separate device connected to the PCRF device. Such as the POP platform shown in fig. 3. Of course, as shown in fig. 1, the POP may also be implemented as a functional module in the PCRF device. The functional modules can be implemented by software, or by both software and hardware. The application is not limited in any way as to the specific implementation of POP.

As shown in fig. 4, an embodiment of the present application provides a policy control method. The method may include S401-S403:

s401, obtaining at least one user event record (EDR) reported by User Equipment (UE).

For example, the EDR may be a signaling carrying a self-location and reported by the UE due to network event triggering such as network registration, cell reselection, cell handover, service initiation or service reception, and the like, or may be a signaling that the UE periodically reports the self-location in the same cell. For example, the EDR may be a measurement report reported by the UE, an IP-CAN session establishment request message, a CCR update request message, a location update reporting signaling, and the like.

For example, EDR usually carries UE identity, reporting time and UE location. The UE identity may be a phone Number of the UE, an International Mobile Subscriber identity Number (IMSI), a Cell Radio Network Temporary identity (C-RNTI), and the like. The reporting time refers to the time for reporting the EDR by the UE. The location of the UE may be at least one of CGI, SAI, RAI, and TAI as described in S201, or may be location information (e.g. longitude and latitude) of the UE located by a NAVIGATION and Positioning module such as a Global Positioning System (GPS), a Global NAVIGATION satellite System (Global NAVIGATION SATELLITE SYSTEM, GLONASS), and beidou.

S402, determining a target area according to the EDR reported by at least one UE.

Wherein the target area satisfies the following condition: the number of the target UEs located in the target area is larger than a preset number threshold; the target UE satisfies any one of the following conditions: the specified service is opened, the staying time in the cells contained in the target area is longer than a first time threshold, switching is carried out in at least two cells contained in the target area, the staying time in each cell is shorter than a second time threshold, and the cells contained in the target area stay in the preset time period.

Illustratively, the three conditions that the target UE needs to satisfy may sequentially correspond to the following three scenarios: the target area to be determined comprises the UE which has opened the specified service, the target area to be determined is a frequently switched scene, and the target area to be determined is a high-load scene. In the embodiment of the present application, the following description will be made for three scenes one by one, and details are not repeated here.

S403, configuring a target control strategy for the target UE located in the target area.

Accordingly, specific target control strategies are respectively given below in the embodiments of the present application for the three scenarios in S402, which are not described herein.

Optionally, the target UE includes a UE that has activated the specified service and has a stay time in a cell included in the target area longer than a first time threshold. The specific service may be a preferential package provided by an operator, and the preferential package may be a communication service that enjoys a better communication experience and a more preferential fee in a specific area. For example, a package of offers for a campus teacher and student in a designated campus area. When the subscribers are located outside the designated area, even if the number of subscribers is large, for example, the ratio of subscribers to all subscribers in the area outside the designated area exceeds 50%, the subscribers cannot enjoy the preferential package. Therefore, the existing policy control method may cause the satisfaction degree of the subscriber to be reduced, and finally, adverse effects are caused to the promotion of the preferential package by the operator. In order to solve this problem, as shown in fig. 5, the embodiment of the present application provides the following solutions: s402 determines a target area according to the EDR reported by at least one UE, and may be implemented as S501-S503, and correspondingly, S403 may be implemented as S504.

S501, determining the cell where the UE is located according to the position of the UE.

Specifically, the cell may be identified according to the location of the UE carried by the EDR.

S502, determining a first proportion of target UE contained in a cell where the UE is located to all the UE in the cell where the UE is located.

Specifically, according to the UE identifier reported by the EDR, the UE list with the specified service activated is matched. If the matching is successful, the UE is considered to have opened the designated service, otherwise, the UE is considered to have not opened the designated service. And then, determining the stay time of the UE in the cell according to the reporting time carried by the EDR. And if the stay time is longer than a preset first time threshold, determining the UE as the target UE. Then, the number of target UEs in the cell and the number of all UEs in the cell are counted, and then the first ratio is calculated.

In practical applications, in order to improve customer satisfaction, for a UE that has already opened a specific service and is located in a preset cell, even if a first ratio of the UE in the preset cell is lower than a first ratio preset threshold, a control policy preset for the specific service should be executed. In other words, the policy control method provided in the embodiment of the present application may also be executed only when the UE that has opened the specified service is located in a non-preset cell. Therefore, optionally, before performing S502 to determine that the target UE included in the cell where the UE is located accounts for the first ratio of all UEs in the cell where the UE is located, the method may further include the following steps:

and determining whether the cell in which the UE is located belongs to a preset cell.

The preset cell is a home service area set by an operator when opening an account for a user. In the home service area, the user can enjoy better service quality and more favorable tariff. Accordingly, outside the home service area, the user cannot enjoy the treatment that the user can enjoy in the home service area. For example, the operator releases a campus package, and in each cell of the campus area, the teacher and the students can enjoy the service quality and the charge set in the campus package, while in other areas outside the campus area, the teacher and the students can still only enjoy the normal service quality and charge.

Exemplarily, the location of the UE carried by the EDR may be matched with a preset cell. If the matching is successful, the cell where the UE is located is regarded as belonging to a preset cell, and a control strategy preset for the specified service is distributed to the UE. Otherwise, if the cell where the UE is located is not a preset cell, the first proportion and the dwell time of the UE need to be counted, and whether a control policy preset for a specified service is allocated to the UE is determined according to a statistical result. Accordingly, S502 determines that the target UE included in the cell where the UE is located accounts for the first ratio of all UEs in the cell where the UE is located, and may be implemented as the following steps to reduce the amount of calculation and improve the efficiency of the policy control method provided in the embodiment of the present application:

and if the cell in which the UE is located does not belong to the preset cell, determining a first proportion of the target UE contained in the cell in which the UE is located to all the UEs in the cell in which the UE is located.

Of course, in practical application, a time period for the UE having the specified service opened to enjoy a better quality service and a better tariff may also be set, so as to simplify the computational complexity of the policy control method provided by the present application. For example, for a campus package, the effective time period of the specified service may be set as a time period in which a normal teaching task exists in the campus area.

S503, if the first ratio is larger than the first ratio threshold, determining that the cell in which the UE is located is the target area.

Optionally, in order to reduce the false determination probability of the target cell, after performing S503, if the first ratio is greater than the first ratio threshold, and determining that the cell where the UE is located is the target area, the method may further include the following two steps:

and after the preset time length, determining a second proportion of the target UE contained in the cell where the UE is located to all the UE in the cell where the UE is located.

For example, the preset time length may be greater than the first time length threshold, or may be less than or equal to the first time length threshold, which is not limited in the embodiment of the present application.

And if the second ratio is larger than the second ratio threshold, determining that the cell in which the UE is located is the target area.

For example, the value of the second proportional threshold may be generally set to be greater than the value of the first proportional threshold, or may be equal to the value of the first proportional threshold, and the embodiment of the present application is not limited.

S504, configuring a target control strategy matched with a preset cell for the target UE located in the target area to support the target UE to execute the designated service. The target UE refers to the UE which has opened the designated service in the target cell.

In practical applications, an operator usually presets a home service area for a premium package offered by the operator, where the home service area may include at least one preset cell. On one hand, as long as the package subscriber is located in the home service area, the subscriber should enjoy better service experience and more favorable tariff. On the other hand, for other areas outside the home service area, when the ratio of the contracted user to all users in the other areas is greater than the preset first ratio threshold, the operator still provides the contracted user with the control strategy preset by the preferential package, so that the experience of the contracted user and the attraction of the preferential package are improved.

Optionally, in frequent handover areas such as high-speed rails and subways, a large amount of network resources are occupied by UE reselection and handover signaling, so that the available network resources cannot meet the communication requirements of all UEs. In the prior art, an operator needs to set a target area (i.e. a target cell set in a frequent handover area) in advance, where QOS control rules and/or charging rules need to be controlled. However, the target area is set by analyzing the historical communication record of the frequent switching area manually or by a third-party device. In other words, the prior art does not have the capability of automatically identifying the frequent switching areas, takes a long time, and obtains the target area inaccurately. For example, as infrastructure construction develops, some non-hot spot areas may become hot spot areas, for example, newly built high-speed rail or subway lines may become new hot spot areas, and the prior art cannot timely identify the hot spot areas and configure a targeted control strategy. Therefore, optionally, as shown in fig. 6, the step S402 of determining the target area according to the EDR reported by at least one UE may be implemented as S601-S602, and correspondingly, the step S403 may be implemented as step S603:

s601, determining the cell where the UE is located according to the position of the UE.

S601 is the same as S501, and is not described herein again.

S602, if the UE is switched between the at least two cells and the stay time of the UE in each cell of the at least two cells is less than a second time threshold, determining an area formed by the at least two cells as a target area.

In practical application, the stay time of the UE which moves fast along with high-speed rails and subways in each cell is short. Therefore, the second duration threshold is typically set to a small value in order to identify cells in the handover frequent region. For example, the second duration threshold may be set to 10 seconds for a high-speed rail scenario. For a subway scenario, the second duration threshold may be set to 1 minute.

S603, configuring a target control strategy with the priority greater than the first priority threshold for the target UE located in the target area.

The first priority threshold refers to that when the number of times of switching of the UEs exceeding the preset number in the specified time period reaches a preset number threshold, the UEs exceeding the preset number need to preferentially guarantee the communication quality. For example, the number of handovers of more than 1000 UEs reaches 20 times within 1 hour, and it is necessary to increase the bandwidth allocated to the UEs exceeding the preset number to ensure the communication quality.

For example, the total bandwidth of the frequent handover area may be preferentially increased, and the bandwidth of the user with the current traffic flow being larger may be limited, so as to ensure that all UEs in the area can normally communicate. The target UE may be all UEs in the target cell.

Optionally, in a person-intensive area such as a mall, a station, etc., there may be a situation where a large number of UEs need to access the wireless network, so that the available network resources cannot meet the communication requirements of a large number of UEs. Therefore, as shown in fig. 7, in order to ensure smooth communication in the person-dense region, a control strategy with higher priority may be configured for the person-dense region. S402 determines a target area according to the EDR reported by at least one UE, which may be implemented as S701 to S703, and accordingly S403 may be implemented as S704:

s701, determining the cell where the UE is located according to the position of the UE.

S701 is the same as S501, and is not described herein again.

S702, determining the number of the UE staying in the same target cell within a preset time period according to the reporting time of the EDR record.

In practical applications, in areas with dense staff, such as shopping malls and stations, users often stay for a long period of time. Therefore, the preset time period may be set to a large value. For example, for a mall scene, the preset time period may be set to 2 hours. For a station scenario, the preset time period may be set to 0.5 hour.

And S703, if the number of the UE is larger than a preset number threshold, determining the target cell as a target area.

The preset number threshold may be determined according to a network capacity of an area where the UE is located. For example, if the wireless network in the area of a certain mall can provide communication service for 10000 people, the preset number threshold can be set to any value of 9000-10000.

S704, configuring a target control strategy with the priority greater than a second priority threshold for the target UE located in the target area.

The second priority threshold is that the number of UEs in the designated area exceeds a preset number threshold, that is, the designated area is considered as a high-load area, the existing network capacity may not meet the communication requirements of a plurality of UEs, and the communication requirements of the UEs in the high-load area need to be guaranteed preferentially. For example, in a region with dense staff, such as a mall and a station, the number of UEs reaches 10000, and it can be considered that the priority of the UE in the region is greater than the second priority threshold.

For example, the total bandwidth of a region with dense people can be preferentially increased, and the bandwidth of a user with larger current traffic flow is limited, so that all UEs in the region can normally communicate. The target UE may be all UEs in the target cell.
