There are many types of conventional access network information, such as the fourth generation mobile communication network technology (the 4th generation mobile communication technology), the fifth generation mobile communication network technology (the5th generation mobile communication technology), the sixth generation mobile communication network technology (the 4th generation mobile communication technology), the fixed network, wifi (wireless fidelity), and others.
In a Policy and charging Control architecture (PCC) defined by the third generation partnership project, a Policy Control Function (PCF) network element can generate a PCC rule according to coal flow information and a requested bandwidth provided by an Application Function (AF) network element, and send the PCC rule to a Session Management Function (SMF) network element for execution, so as to trigger the Session Management Function network element to establish a dedicated bearer to a terminal device side.
The inventor of the present application finds, through long-term research, that differences of different access network information are not considered in existing policy and charging control methods for a terminal device, no matter when a PCC policy is constructed or when the PCC policy is issued, because guaranteed bandwidths that can be supported by different access network information are very different, when the terminal device switches access network information, establishing a dedicated bearer with a session management function network element according to a preset PCC policy fails, for example, when a user is in a 5G network technology, a maximum downlink bandwidth for issuing the PCC policy is 20Mbps, and accordingly establishing a dedicated bearer with the session management function network element, when the user switches to the 4G network technology, the dedicated bearer is failed to establish because the 4G network technology does not support the PCC policy, and when the terminal device switches to the 5G network technology again, the PCC policy also needs to be issued again. Based on this, the embodiment of the application performs policy and charging control on the terminal device based on the PCC policy corresponding to the current access network information, thereby reducing the possibility of failure in establishing the dedicated load with the session management function network element by the terminal device. In addition, when a 6G technology is introduced in the future, differences necessarily exist in bandwidth and service deployment capacity in a scene where multi-access network information exists, and the capacity of issuing different PCC policies based on different access network information needs to be supported.
In this embodiment, the terminal device may be a smart phone, a tablet Computer, a PC (Personal Computer), an intelligent voice interaction device, an intelligent household appliance, a vehicle-borne terminal, or other electronic devices, which is not limited herein.
To solve at least the above problems in the prior art, embodiments of the present application respectively propose a policy and charging control method, a policy and charging control apparatus, an electronic device, and a computer-readable storage medium, which will be described in detail below with respect to these embodiments.
Referring to fig. 1, fig. 1 is a flowchart illustrating a policy and charging control method according to an exemplary embodiment of the present application. The policy and charging control method provided in this embodiment is applied to a policy control function network element or a session management function network element in a 5G or future 6G core network defined by the third generation partnership project.
As shown in fig. 1, the policy and charging control method provided in this embodiment includes steps S101 to S103, and the following is referred to for detailed description:
step S101: and acquiring the current access network information of the terminal equipment.
In this embodiment, the current access network information of the terminal device is the access network information supported by the current access wireless network of the terminal device. When a terminal device initiates a service, a session management function network element receives a PDU session establishment request, where the request includes current access network information of the terminal device, and after receiving the session request, if an execution subject of this embodiment is a policy control function network element, the session management function network element sends SM policy association creation or modification to the policy control function network element, where the SM policy association creation or modification carries service information of the service initiated by the terminal device and the current access network information of the terminal device. Illustratively, the session management function network element periodically sends a request instruction to the terminal device, where the request instruction is used to instruct to acquire current access network information of the terminal device, so that the terminal device reports its current access network information to the session management function network element in response to the request instruction. The present embodiment may also obtain the current access network information of the terminal device through other various manners, which is not limited herein.
For example, considering that the current access network information of the terminal device may change from time to time, the terminal device performs network handover according to the signal strength of the access network information, for example: the terminal equipment firstly uses the data service in the 4G network coverage area, and when the subsequent terminal equipment moves out of the 5G network coverage area, the terminal equipment needs to be switched from the 4G network to the 5G network. Illustratively, the terminal device performs network switching according to the access network information priority set by the operator. For example: the terminal equipment firstly uses the data service in the area covered by the 4G network, and when the subsequent terminal equipment moves to the area covered by the 5G network, the user switches from the 4G network to the 5G network because the 5G network priority set by the operator is higher than that of the 4G network.
Therefore, in order to ensure the accuracy of the acquired current access network information of the terminal device, the present embodiment receives a handover message for the access network information of the terminal device, where the handover message includes the current access network information of the terminal device. By the method, the current access network information of the terminal equipment can be updated at any time.
In the present embodiment, since the types of the base stations of the wireless access systems corresponding to different access network information are different, in the case that the access network information supported by the first communication base station and the second communication base station is different, it is described that the terminal device has switched the access network information, and in this case, the handover message is generated.
It should be noted that the above manner of acquiring the current access network information of the terminal device is only an exemplary embodiment, and this embodiment may also acquire the current access network information of the terminal device through other manners, for example, the current access network information is acquired based on a network registration update message of the terminal device, which is not limited specifically herein.
Step S102: and determining a target PCC strategy corresponding to the current access network information.
In this step, the policy control function network element or the session management function network element stores a plurality of pieces of access network information adapted to the terminal device and a PCC policy corresponding to each piece of access network information in advance. Therefore, the acquired current access network information can be matched with a plurality of pre-stored access network information, and a target PCC policy corresponding to the current access network information is further determined.
Illustratively, if there is no target PCC policy corresponding to the current access network information, sending feedback information indicating that obtaining the PCC policy fails to the terminal device, so that the terminal device sends a service request to the application function network element based on the feedback information, so that the application function network element sends a request bandwidth corresponding to the current access network information to the policy control function network element, so that the policy control function network element configures the PCC policy for the current access network information based on the request bandwidth corresponding to the current access network information, and controls the data flow of the terminal device based on the target PCC policy.
Step S103: and controlling the data flow of the terminal equipment based on the target PCC strategy.
In this embodiment, if the execution subject is a policy control function network element, the target PCC policy is issued to the session management function network element, so that the session management function network element executes the target PCC policy to control the data flow of the terminal device.
In this embodiment, if the executing entity is a session management function network element, the multiple access network information sent by the policy control function network element and the PCC policy corresponding to each access network information are received, then a target PCC policy corresponding to the current access network information is determined from the multiple obtained PCC policies, and the data flow of the terminal device is controlled based on the target PCC policy.
In this embodiment, the session management function network element establishes a dedicated bearer between the terminal device and the target PCC rule, and is configured to transmit the media stream information of the application function network element that sends the request information, so as to ensure transmission of the media stream information of the application function network element.
Illustratively, if the execution main body is a policy control function network element, the policy control function network element learns that the current access network information of the terminal device is E-UTRAN (4G), and issues a target PCC rule that the uplink guaranteed bandwidth is 10Mbps and the downlink guaranteed bandwidth is 10Mbps to the session management function network element. After receiving the target PCC rule, the session management function network element establishes a dedicated bearer with an uplink guaranteed bandwidth of 10Mbps and a downlink guaranteed bandwidth of 10Mbps with the terminal device, and is used for transmitting media stream information of the application function network element. Illustratively, the policy control function network element issues the target PCC policy to the session management function network element through an N7 interface.
Illustratively, the policy control function network element or the session management function network element executing the target PCC policy to control the data flow of the terminal device includes Quality of Service (QoS) control, charging control, and threshold control of the traffic flow of the terminal device.
The policy and charging control method provided in this embodiment obtains a target PCC policy corresponding to current access network information based on the current access network information of a terminal device, and controls a data flow of the terminal device based on the target PCC policy.
Referring to fig. 2, fig. 2 is a flowchart of a policy and charging control method shown in an exemplary embodiment that is proposed on the basis of the embodiment in fig. 1, where the policy and charging control method provided in this embodiment is applied to a policy control function network element, as shown in fig. 2, before step S101, the policy and charging control method provided in this embodiment further includes step S201-step S202, and reference is made to the following in detail:
step S201: and receiving request information sent by the application function network element or the capability opening function network element.
In this embodiment, the request information includes a plurality of access network information adapted to the terminal device and a request bandwidth corresponding to each access network information. Illustratively, access network information such as RatType, AccessType and the like and corresponding policies are added to the interfaces of the application function network element and the capability openness function network element and the interfaces of the capability openness function network element and the policy control function network element, so that the application function network element or the capability openness function network element can smoothly send the access network information such as RatType, AccessType and the like and the corresponding policies to the policy control function network element. For example, RatType ═ NR ", qsref ═ 1 (corresponding to a maximum bandwidth of 20Mbps), RatType ═ EUTRA", and qsref ═ 2 (corresponding to a maximum bandwidth of 4 Mbps); RatType ═ wire ", qsference ═ 3 (corresponding to a maximum bandwidth of 100Mbps), and so on.
It should be noted that, in this embodiment, the request message may include, in addition to the request bandwidth corresponding to each access network information, offloading information corresponding to each access network information, and the like, for constructing the PCC policy corresponding to the access network information, which is not specifically limited herein.
Illustratively, each request bandwidth includes an uplink bandwidth parameter value and a downlink bandwidth parameter value, and one request bandwidth is suitable for one type of access network information, for example, the uplink request bandwidth of request bandwidth 1 is 4Mbps, the downlink request bandwidth is 4Mbps, and the corresponding access network information is EUTRA (4G); the uplink request bandwidth of the request bandwidth 2 is 20Mbps, the downlink request bandwidth is 20Mbps, and the corresponding access network information is NR (5G). In this embodiment, the request information further includes media stream information requested by the terminal device, (a technology for playing streaming media on the Internet is a media stream by using a streaming transmission mode), where the media stream information corresponds to a service request sent by the terminal device to the application function network element, and the media stream information includes media stream parameters, and the media stream parameters include an IP address and a port of the terminal device, QoS information, and the like.
Illustratively, the request bandwidth corresponding to each piece of access network information in the request information is obtained by the network element with application function invoking capability openness function. Exemplarily, if the access network information is access type1, for example, 3GPP access, non-3GPP access, etc., the corresponding Charging information (for example, rate group, etc.) is Charging Info1 and QoS information is QoS Profile1, and the current access network information is access type2, then the Charging information is Charging Info2 and the QoS information is QoS Profile 2.
Illustratively, if the access network information is AccessType1, according to QoS Profile1, the uplink request bandwidth of the request bandwidth 1 is 4Mbps, and the downlink request bandwidth is 4 Mbps; if the access network information is the AccessType2, according to the QoS Profile 2, which is the QoS information, the uplink request bandwidth of the request bandwidth 2 is 20Mbps, and the downlink request bandwidth is 20 Mbps.
Step S202: and respectively configuring a corresponding PCC strategy for each piece of access network information based on the request bandwidth corresponding to each piece of access network information.
In this embodiment, the PCC policy corresponding to the access network information includes a QoS index, a offload identifier, and the like, where the QoS index includes, for example, a maximum uplink bandwidth, a maximum downlink bandwidth, and the offload identifier includes, for example, DNAI, and the like, and is not specifically limited herein.
In this embodiment, the policy control function network element configures, for each piece of access network information, a corresponding PCC policy according to a bandwidth parameter value of a requested bandwidth corresponding to each piece of access network information in the request information.
The inventor of the present application finds, through long-term research, that when current access network information of a terminal device changes, a policy control function network element needs to perform signaling interaction with an application function network element to obtain a request bandwidth corresponding to the changed access network information, and then generates a new PCC rule according to the request bandwidth corresponding to the changed access network information.
Based on this, in this embodiment, the policy control function network element receives request information of the application function network element, where the request information includes multiple pieces of access network information adapted to the terminal device and a request bandwidth corresponding to each piece of access network information, and then multiple PCC rules are determined according to the request information. Therefore, when the current access network information of the terminal equipment is changed, the PCC rules corresponding to the current access network information are directly determined from the PCC strategies stored in the strategy control function network element, the signaling interaction times between the strategy control function network element and the application function network element are reduced, the signaling overhead of a PCC framework is reduced, and network resources are saved.
Illustratively, each PCC policy corresponding to the configuration of the access network information adapted to the terminal device is issued to the session management function network element, so that the session management function network element determines a target PCC policy corresponding to the current access network information, and then controls the data flow of the terminal device based on the target PCC policy. For example, the session management function network element receives the PCC rule 1 and the PCC rule 2 sent by the policy control network element, determines that the current access network information of the terminal device is E-UTRAN (4G), the PCEF network element selects and executes the PCC rule 2 corresponding to the current access network information, and establishes a dedicated bearer with an uplink guaranteed bandwidth of 10Mbps and a downlink guaranteed bandwidth of 10Mbps with the terminal device.
By the above manner, the target PCC rule corresponding to the changed access network information can be used without reporting the current access network information change event of the terminal device to the policy control function network element or waiting for the policy control function network element to issue a new target PCC rule.
Illustratively, in order to make the correspondence between the access network information and the PCC policy clearer, a correspondence table including each access network information and the PCC policy corresponding to each access network information is constructed, so as to determine a target PCC policy corresponding to the current access network information through the correspondence table. Specifically, the target PCC strategy corresponding to the current access network information is directly determined in a table look-up mode, and all pairs of the access network information and the PCC strategy do not need to be traversed, so that the efficiency of determining the target PCC strategy corresponding to the current access network information is improved.
