The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
当前的无线通信网络有三种接入技术，一种是全球移动通讯***（Global System of Mobile communication, 简称为 GSM) ， 通常称为 2G; ——禾中是通 用禾多动通信*** (Universal Mobile Telecommunications System, 简禾尔为 UMTS) ， 通常称为 3G; 以及长期演进 （Long Term Evolved, 简称为 LTE) 系 统， 通常称为 4G。 三种接入技术下的***架构如图 1所示。  The current wireless communication network has three access technologies, one is the Global System of Mobile communication (GSM), commonly referred to as 2G; - Wozhong is the Universal Mobile Telecommunications system (Universal Mobile Telecommunications) System, Jane is UMTS), commonly referred to as 3G; and Long Term Evolved (LTE) system, commonly referred to as 4G. The system architecture under the three access technologies is shown in Figure 1.
无论是哪种接入技术下的网络架构均可分成两个部分， 一个是接入网部 分， 一个核心网部分。 核心网部分又分为移动性管理网元、 网关设备及 PCC 部分。 接入网部分主要负责无线接入层信令以及用户数据传输， 具体的， 在 GSM中，接入网部分主要是指图 1中的 GERAN (英文为： GSM EDGE Radio Access Network)，包括 BTS和 BSC;在 UMTS中，接入网部分主要是指图 1中的 UTRAN, 包括 RNC和 NodeB; 在 LTE***中， 接入网部分主要是指图 1中的 E-UTRAN, 包括 eNodeB。 图 1所示架构中除接入网部分之外的其它部分为核心网部分， 其中， GSM和 UMTS的 SGSN以及 LTE***中的匪 E被称为移动性管理网元， 主要用于获取用户的签约数据， 负责 NAS信令和 NAS信令加密以及漫游、 跟 踪等功能， 分配用户临时身份标识、 安全功能等。 GSM和 UMTS中的 GGSN以 及 LTE***中的 PGW是网关设备， 主要负责策略执行和计费以及合法监听相 关功能。 另外， 核心网中还有一个重要组成部分是 PCC部分， 其包括 PCRF实 体和 PCEF实体， PCEF实体通常与网关设备， 例如 GGSN或 PGW合设， 并与用 户签约数据库 (Subscription Profile Repository, 简称为 SPR) 、 应用功 能 （Application Function, 简称为 AF) 实体等一起实现 PCC部分的作用。 图 1中未示出 SPR。  No matter which access technology network architecture can be divided into two parts, one is the access network part, one core network part. The core network part is further divided into a mobility management network element, a gateway device, and a PCC part. The access network part is mainly responsible for radio access layer signaling and user data transmission. Specifically, in GSM, the access network part mainly refers to GERAN (English: GSM EDGE Radio Access Network) in Figure 1, including BTS and BSC; In UMTS, the access network part mainly refers to the UTRAN in FIG. 1, including the RNC and the NodeB; in the LTE system, the access network part mainly refers to the E-UTRAN in FIG. 1, including the eNodeB. The other part of the architecture shown in Figure 1 except the access network part is the core network part. The SGSN of GSM and UMTS and the 匪E of the LTE system are called mobility management network elements, which are mainly used to acquire users. Signing data, responsible for NAS signaling and NAS signaling encryption, roaming, tracking, etc., assigning user temporary identity, security functions, etc. The GGSN in GSM and UMTS and the PGW in the LTE system are gateway devices, which are mainly responsible for policy enforcement and charging and lawful interception related functions. In addition, an important component of the core network is the PCC part, which includes a PCRF entity and a PCEF entity. The PCEF entity is usually combined with a gateway device, such as a GGSN or a PGW, and is subscribed to a database (Subscription Profile Repository, SPR for short). ), Application Function (AF) entities, etc. together implement the PCC part. SPR is not shown in Figure 1.
PCRF实体主要是根据运营商策略、 对用户接入网络的限制、 用户签约数 据以及用户当前正在进行的 SDF的业务信息等因素， 制定对应的策略， 该策 略称为 PCC规则； PCEF实体主要是执行 PCRF实体制定的 PCC规则， 例如根 据 PCC 规则， 对 SDF进行检测和测量， 保证业务的服务质量 （Quality of Service, 简称为 QoS) ， 用户面流量检测和触发控制面的会话管理等等。 进 一步说明，为保证业务的 QoS，UE发出的所有互联网协议（Internet Protocol , 简称为 IP) 数据包或待接收的所有 IP数据包需要经过 PCEF, 由 PCEF根据 SDF的 QoS参数将服务数据流与承载绑定， 比如将 QoS分类标识 （QoS Class Identifier, 简称为 QCI ) 与地址解析协议 (Address Resolution Protocol , 简称为 ARP) 相同的服务数据流绑定在同一个承载上， 以便于核心网中的其 他网元基于承载执行流控。 另外， PCEF还会根据 PCRF下发的计费策略与计 费方式等， 对收到的服务数据流等。 The PCRF entity is mainly based on the operator's policy, restrictions on user access to the network, and number of user subscriptions. According to factors such as the service information of the SDF currently being performed by the user, a corresponding policy is formulated, which is called a PCC rule; the PCEF entity mainly performs a PCC rule formulated by the PCRF entity, for example, detecting and measuring the SDF according to the PCC rule, Quality of Service (QoS), user-side traffic detection, and session management for triggering control planes. Further, in order to guarantee the QoS of the service, all Internet Protocol (IP) data packets sent by the UE or all IP data packets to be received need to pass through the PCEF, and the PCEF will serve the data flow and bearer according to the QoS parameters of the SDF. Binding, for example, the QoS Class Identifier (QCI) is the same as the Address Resolution Protocol (ARP) service data flow on the same bearer, so as to facilitate other core networks. The network element performs flow control based on the bearer. In addition, the PCEF will also receive the service data stream according to the charging policy and charging method delivered by the PCRF.
目前，对用户的业务数据进行计费是由 PCEF实体执行基于 SDF粒度的计 费。 当前的 3GPP组织中正在讨论基于应用数据流的计费。 针对当前 3GPP组 织正在讨论的基于应用数据流的计费， 本发明实施例提供了以下两种解决方 案。 一种是在业务检测功能 （Traffic Detection Function, 简称为 TDF) 实体上执行基于应用数据流的计费方案，另一种是在 PCEF实体上执行基于应 用数据流的计费方案。  Currently, charging the user's business data is performed by the PCEF entity based on the SDF granularity. Application data flow based charging is being discussed in current 3GPP organizations. The present invention provides the following two solutions for the application data flow based charging that is currently being discussed by the 3GPP organization. One is to implement an application data flow-based charging scheme on a Traffic Detection Function (TDF) entity, and the other is to implement an application data flow-based charging scheme on a PCEF entity.
其中， TDF实体是深度包检测 （Deep Packet Inspection, 简称为 DPI ) 设备的一种功能实体，能够根据 PCRF实体下发的对数据包的探测规则对数据 包执行检测， 例如检测某类应用 （QQ) 的数据包， 或者检测指定的统一资源 定位符 （Uniform Resource Locator, 简称为 URL) 的数据包等， 在检测到 满足条件的应用数据包后， 向 PCRF实体上报该数据包事件。 另外， TDF实体 也可能对检测到的应用数据包执行流控， 例如上下行的最大比特率限制。 图 2所示为无线通信***控制与管理中， 控制面与用户面的数据流接口与方向。 如图 2所示中带箭头的虚线所示， UE发送的上行数据包要先经过 PCEF实体， 再经过 TDF实体才能到达网络侧， 相应的， 如图 2中带箭头的实线所示， 网 络侧发送的下行数据包要先经过 TDF实体， 再经过 PCEF实体才能到达 UE。  The TDF entity is a functional entity of the Deep Packet Inspection (DPI) device, and can perform detection on the data packet according to the detection rule of the data packet sent by the PCRF entity, for example, detecting a certain type of application (QQ). The data packet, or the data packet of the specified Uniform Resource Locator (URL), is detected, and the packet event is reported to the PCRF entity after detecting the application data packet that satisfies the condition. In addition, the TDF entity may also perform flow control on the detected application data packets, such as the maximum bit rate limit of uplink and downlink. Figure 2 shows the data flow interface and direction of the control plane and the user plane in the control and management of the wireless communication system. As shown by the dotted line with an arrow in FIG. 2, the uplink data packet sent by the UE first passes through the PCEF entity, and then passes through the TDF entity to reach the network side, correspondingly, as shown by the solid line with an arrow in FIG. 2, the network The downlink data packet sent by the side must pass through the TDF entity before passing through the PCEF entity to reach the UE.
在第一种解决方案中， 对于上行数据包来说， 有可能经过 PCEF实体基于 SDF粒度的计费后， 又经过 TDF实体基于应用数据流的计费， 存在重复计费 导致计费不准确； 对于下行数据流来说， 由于 PCEF实体要执行 SDF的 QoS策 略， 可能会丢弃在 TDF实体已经计费的数据包， 也会导致计费不准确。 In the first solution, for the uplink data packet, it is possible to pass the SDF granularity-based charging of the PCEF entity, and then the TDF entity is based on the application data flow-based charging, and the repeated charging causes the charging to be inaccurate; For the downlink data stream, because the PCEF entity is to implement the SDF QoS policy Slightly, the packets that have been billed in the TDF entity may be discarded, which may result in inaccurate billing.
在第二种解决方案中， TDF 实体探测到下行数据包所属的应用后， 标识 这种下行数据包， 以便于 PCEF实体根据该标识识别下行数据包所属的应用， 并对其进行计费， 实现基于应用数据流的计费， 但是对于上行数据包， PCEF 实体无法识别上行数据包所属的应用，只有在执行完基于 SDF粒度的计费后， 将上行数据包送入 TDF实体， 由 TDF实体检测上行数据包所属的应用， 并反 馈给 PCEF实体， 此时 PCEF实体再对该上行数据包进行计费， 实现基于应用 数据流的计费， 这就存在重复计费的问题， 也会导致计费不准确。  In the second solution, after detecting the application to which the downlink data packet belongs, the TDF entity identifies the downlink data packet, so that the PCEF entity identifies the application to which the downlink data packet belongs according to the identifier, and performs charging, thereby implementing Based on the application data flow-based charging, but for the uplink data packet, the PCEF entity cannot identify the application to which the uplink data packet belongs, and only after performing the SDF granularity-based charging, the uplink data packet is sent to the TDF entity, and the TDF entity detects The application to which the uplink data packet belongs is fed back to the PCEF entity. At this time, the PCEF entity charges the uplink data packet to implement charging based on the application data flow, which has the problem of repeated charging, and also causes charging. Inaccurate.
针对当前 3GPP组织中正在讨论基于应用数据流的计费， 以及本发明上面 提供的解决方案存在的问题， 本发明以下实施例给出了更加详细完善的解决 方案。  The following embodiments of the present invention provide a more detailed and complete solution to the problems that are currently being discussed in application-based data flow-based charging in the 3GPP organization, and the solutions provided above.
本发明提供的第一种计费方法的主要思路是： 由 PCRF实体确定需要计费 的第一应用， 并为第一应用分配计费标识， 通过所述计费标识标识需要对第 一应用进行单独计费；然后 PCRF实体将第一应用的标识和为第一应用分配的 计费标识分别发送给 TDF实体、 PCEF实体和 UE; 这样， UE向 PCEF实体发送 第一应用的上行数据包之前，在第一应用的上行数据包中添加所述计费标识， 然后将添加所述计费标识的上行数据包发送给 PCEF实体， PCEF实体就可以 对接收到的携带有所述计费标识的上行数据包进行单独计费， 实现在上行方 向对第一应用的单独计费， 并且因为可以标识第一应用的上行数据包因此不 存在重复计费的问题； 同理， TDF实体在向 PCEF实体发送第一应用的下行数 据包之前， 在第一应用的下行数据包中添加所述计费标识， 然后将添加所述 计费标识的上行数据包发送给 PCEF实体， PCEF实体就可以对接收到的携带 有所述计费标识的下行数据包进行单独计费， 实现在下行方向上对第一应用 的单独计费， 因为可以标识第一应用的下行数据包所以不存在重复计费的问 题。  The main idea of the first charging method provided by the present invention is: determining, by the PCRF entity, the first application that needs to be charged, and assigning a charging identifier to the first application, where the charging identifier needs to be used for the first application. Separate billing; then the PCRF entity sends the identifier of the first application and the charging identifier assigned to the first application to the TDF entity, the PCEF entity, and the UE respectively; thus, before the UE sends the uplink packet of the first application to the PCEF entity, Adding the charging identifier to the uplink data packet of the first application, and then sending the uplink data packet that adds the charging identifier to the PCEF entity, where the PCEF entity can receive the received uplink carrying the charging identifier. The data packet is separately charged, and the first application is separately charged in the uplink direction, and since the uplink data packet of the first application can be identified, there is no problem of repeated charging; similarly, the TDF entity sends the data to the PCEF entity. Before the downlink data packet of the first application, adding the charging identifier to the downlink data packet of the first application, and then adding the charging identifier The uplink data packet is sent to the PCEF entity, and the PCEF entity can separately charge the received downlink data packet carrying the charging identifier to implement separate charging for the first application in the downlink direction, because the first packet can be identified.

图 3为本发明实施例提供的一种计费方法的流程图。 如图 3所示， 所述 方法包括：  FIG. 3 is a flowchart of a charging method according to an embodiment of the present invention. As shown in FIG. 3, the method includes:
11、 PCEF 实体接收服务网关设备发送的互联网连接访问网络 ( IP-Connectivity Access Network, 简称为 IP-CAN) 承载建立请求消息。  11. The PCEF entity receives an IP-Connectivity Access Network (IP-CAN) bearer setup request message sent by the serving gateway device.
具体的， PCEF实体接收服务网关设备， 例如 SGW发送的 IP-CAN承载建 立请求消息， 所述 IP-CAN承载建立请求消息包括 UE的标识等信息， 用于建 立承载。  Specifically, the PCEF entity receives the service gateway device, for example, an IP-CAN bearer setup request message sent by the SGW, where the IP-CAN bearer setup request message includes information such as the identifier of the UE, and is used to establish a bearer.
12、 PCEF实体向 PCRF实体发送 IP-CAN会话建立请求消息。  12. The PCEF entity sends an IP-CAN session establishment request message to the PCRF entity.
13、 PCRF实体确定需要计费的第一应用， 并为需要计费的第一应用分配 计费标识， 以标识需要对第一应用进行单独计费。  13. The PCRF entity determines the first application that needs to be charged, and allocates a charging identifier to the first application that needs to be charged, to identify that the first application needs to be separately charged.
在此说明， 这里的第一应用可以是任何需要进行计费的应用， 为便于描 述， 冠以 "第一" ， 但并没有个数限定的意思。  Herein, the first application here may be any application that needs to be charged. For the convenience of description, it is referred to as "first", but there is no limit to the number.
例如， PCRF可以为第一应用分配相应的差分服务代码点（Differentiated Services Code Point, 简称为 DSCP) 值， 以便于在数据包的 IP头中的 DSCP 位采用相应的值标识需要对第一应用进行计费。 14、 PCRF实体向 TDF实体发送 TDF会话建立请求消息， 该 TDF会话建立 请求消息包括第一应用的标识 （APPLICATION ID) 以及计费标识， 例如 DSCP 值。 For example, the PCRF may allocate a corresponding differentiated service code point (DSCP) value to the first application, so that the DSCP bit in the IP header of the data packet is identified by the corresponding value to be used for the first application. Billing. 14. The PCRF entity sends a TDF session establishment request message to the TDF entity, where the TDF session establishment request message includes an identifier of the first application (APPLICATION ID) and a charging identifier, such as a DSCP value.
15、 TDF实体向 PCRF实体发送 TDF会话建立响应消息。  15. The TDF entity sends a TDF session setup response message to the PCRF entity.

其中 ， 第一应用 的标识也就是需要计费的应用 的标识 ( Char ged-app 1 i cat i on identifier) 。  The identifier of the first application is the identifier of the application to be charged (Char ged-app 1 i cat i on identifier).
PCRF实体在为第一应用分配计费标识后， 一方面将第一应用的标识和为 第一应用分配的计费标识提供给 TDF实体， 另一方面还需要将第一应用的标 识和为第一应用分配的计费标识提供给 PCEF实体， 以便于 PCEF实体基于这 两个信息， 对第一应用的上行和下行数据包进行计费。  After assigning the charging identifier to the first application, the PCRF entity provides the identifier of the first application and the charging identifier allocated for the first application to the TDF entity, and the identifier of the first application is also required to be An application-assigned charging identifier is provided to the PCEF entity, so that the PCEF entity charges the uplink and downlink data packets of the first application based on the two information.

另外， 本实施例对第一应用的标识的实现不做限定。 举例说明， 如果需 要对新浪（Sina ) 网页的应用数据包计费， 那么可能将胃 . sina. com作为第 一应用的标识包含在 PC0中， 但不限于此。 In addition, this embodiment does not limit the implementation of the identifier of the first application. For example, if needed To charge the application data package of the Sina (Sina) webpage, it is possible to include the stomach. sina.com as the identifier of the first application in the PC0, but is not limited thereto.
18、服务网关设备接收到 IP-CAN承载建立响应消息后， 经过移动性管理 网元向 UE 透传第一应用的标识和为第一应用分配的计费标识， 例如可以向 UE透传 IP-CAN承载建立响应消息中的 PC0。  After the service gateway device receives the IP-CAN bearer setup response message, the mobility management network element transparently transmits the identifier of the first application and the charging identifier allocated to the first application to the UE, for example, the IP may be transparently transmitted to the UE. The CAN bearers the PC0 in the response message.
19、 UE收到第一应用的标识和为第一应用分配的计费标识后， 在第一应 用的上行数据包中添加该计费标识， 并将添加计费标识的第一应用的上行数 据包发送给 PCEF实体。  After receiving the identifier of the first application and the charging identifier allocated for the first application, the UE adds the charging identifier to the uplink data packet of the first application, and adds the uplink data of the first application of the charging identifier. The package is sent to the PCEF entity.
20、 PCEF实体收到 UE发送的携带有计费标识的上行数据包时， 对接收 到的数据包执行单独计费。  20. When receiving the uplink data packet carrying the charging identifier sent by the UE, the PCEF entity performs separate charging on the received data packet.
通过本实施例的方法， PCEF实体收到 UE发送的上行数据包后， 能够通过其 携带的计费标识获知该上行数据包属于需要进行计费的第一应用， 从而实现 在上行方向上对第一应用的单独计费。 另外， PCEF实体收到 TDF实体发送的 下行数据包后， 能够通过其携带的计费标识获知该下行数据包属于需要进行 计费的第一应用， 从而实现在下行方向上对第一应用的单独计费。 另外， 本 实施例提供的计费方法在 PCEF实体上实现，与现有技术中基于 SDF的计费在 同一设备上执行， 因此， 不存在重复计费造成的计费不准确的问题。  After receiving the uplink data packet sent by the UE, the PCEF entity can learn, by using the charging identifier carried by the PCEF, that the uplink data packet belongs to the first application that needs to be charged, thereby implementing the uplink application in the uplink direction. Separate billing for an application. In addition, after receiving the downlink data packet sent by the TDF entity, the PCEF entity can learn that the downlink data packet belongs to the first application that needs to be charged by using the charging identifier carried by the PCEF entity, thereby implementing a separate application for the first application in the downlink direction. fee. In addition, the charging method provided in this embodiment is implemented on the PCEF entity, and the SDF-based charging in the prior art is performed on the same device. Therefore, there is no problem of charging inaccuracy caused by repeated charging.
图 4为本发明实施例提供的另一种计费方法的流程图。 如图 4所示， 所 述方法包括：  FIG. 4 is a flowchart of another charging method according to an embodiment of the present invention. As shown in Figure 4, the method includes:
41、 TDF实体探测到需计费的第一应用的数据包时， 向 PCRF实体上报业 务流探测事件， 该业务流探测事件包括第一应用的标识等信息。  When the TDF entity detects the data packet of the first application to be charged, the TSF entity reports the service flow detection event to the PCRF entity, where the service flow detection event includes information such as the identifier of the first application.
具体的， TDF实体可以根据 PCRF实体之前下发的对数据包的探测规则， 对接收到的数据包进行探测。 基于此， TDF 实体可以探测到哪些应用的数据 包需要进行单独计费。 具体需要对哪些应用进行单独进行计费可以根据运营 商的要求而定。 其中， 第一应用可以是任何需要计费的应用。 当探测到需要 计费的第一应用时， TDF实体向 PCRF实体上报业务流探测事件， 以使 PCRF 实体为第一应用分配计费标识并确定修改 ADC规则。  Specifically, the TDF entity may detect the received data packet according to the detection rule of the data packet sent by the PCRF entity. Based on this, the TDF entity can detect which application packets need to be billed separately. Which applications need to be billed separately can be determined according to the requirements of the operator. The first application may be any application that requires charging. When the first application that needs to be charged is detected, the TDF entity reports the service flow detection event to the PCRF entity, so that the PCRF entity allocates a charging identifier to the first application and determines to modify the ADC rule.
42、 PCRF实体收到业务流探测事件后， 根据其中第一应用的标识确定第 一应用，并为第一应用分配计费标识，例如所分配的计费标识可以是 DSCP值。  After receiving the service flow detection event, the PCRF entity determines the first application according to the identifier of the first application, and allocates a charging identifier to the first application. For example, the allocated charging identifier may be a DSCP value.
其中， 计费标识主要用于标识需要对第一应用的数据包进行计费， 例如 对于 UE来说， 需要在第一应用的上行数据包中添加该计费标识， 对于 PCEF 实体来说， 需要基于该计费标识， 确定需要计费的第一应用以及第一应用的 上行数据包； 而对 TDF实体来说， 需要在第一应用的下行数据包中添加该计 费标识， 对于 PCEF实体来说， 需要基于该计费标识， 确定需要计费的第一应 用以及第一应用的下行数据包。 The charging identifier is mainly used to identify that the data packet of the first application needs to be charged, for example, For the UE, the charging identifier needs to be added to the uplink data packet of the first application. For the PCEF entity, the first application that needs to be charged and the uplink data packet of the first application are determined based on the charging identifier. For the TDF entity, the charging identifier needs to be added to the downlink data packet of the first application. For the PCEF entity, the first application that needs to be charged and the first application are determined based on the charging identifier. Downstream packet.
43、 PCRF实体向 TDF实体发送修改 ADC规则消息， 该消息包括第一应用 的标识 （APPLICATION ID) 以及为第一应用分配的计费标识， 例如 DSCP值。  43. The PCRF entity sends a modified ADC rule message to the TDF entity, where the message includes an identifier of the first application (APPLICATION ID) and a charging identifier assigned to the first application, such as a DSCP value.
可选的， 本实施例提供的方法还可以包括： TDF 实体收到第一应用的标 识和为第一应用分配的计费标识后， 在第一应用的下行数据包中添加该计费 标识， 并将添加计费标识的第一应用的下行数据包发送给 PCEF 实体； PCEF 实体收到 TDF实体发送的携带有计费标识的下行数据包时， 对该类数据包执 行计费。  Optionally, the method provided in this embodiment may further include: after receiving the identifier of the first application and the charging identifier allocated to the first application, the TDF entity adds the charging identifier to the downlink data packet of the first application, And sending the downlink data packet of the first application that adds the charging identifier to the PCEF entity; when receiving the downlink data packet that is sent by the TDF entity and carrying the charging identifier, the PCEF entity performs charging for the data packet.
PCRF实体在为第一应用分配计费标识后， 将第一应用的标识和为第一应 用分配的计费标识提供 TDF实体， 使得 TDF实体可以识别第一应用与分配给 第一应用的计费标识之间的对应关系， 进而便于 TDF在下行方向对该第一应 用按照所述计费标识 （例如 DSCP值） 进行标识， 使得 PCEF实体收到 TDF发 送的下行数据包后能够识别出下行数据包属于需要进行计费的第一应用， 从 而在下行方向上实现对第一应用的单独计费， 且不存在重复计费的问题。  After assigning the charging identifier to the first application, the PCRF entity provides the TDF entity with the identifier of the first application and the charging identifier allocated for the first application, so that the TDF entity can identify the first application and the charging allocated to the first application. Corresponding relationship between the identifiers, so that the TDF can identify the first application according to the charging identifier (for example, a DSCP value) in the downlink direction, so that the PCEF entity can identify the downlink data packet after receiving the downlink data packet sent by the TDF. It belongs to the first application that needs to perform charging, so that separate charging for the first application is implemented in the downlink direction, and there is no problem of repeated charging.
44、 PCRF实体向 PCEF实体发送策略与计费规则消息， 该消息包括第一 应用的标识和为第一应用分配的计费标识。  44. The PCRF entity sends a policy and charging rule message to the PCEF entity, where the message includes an identifier of the first application and a charging identifier allocated for the first application.
其中 ， 第一应用 的标识也就是需要计费的应用 的标识 ( Char ged-app 1 i cat i on identifier ) 。  The identifier of the first application is the identifier of the application to be charged (Char ged-app 1 i cat i on identifier ).
PCRF实体在为第一应用分配计费标识后， 一方面将第一应用的标识和为 第一应用分配的计费标识提供给 TDF实体， 另一方面还需要将第一应用的标 识和为第一应用分配的计费标识提供给 PCEF实体， 以便于 PCEF实体基于这 两个信息， 对第一应用的上行和下行数据包进行计费。  After assigning the charging identifier to the first application, the PCRF entity provides the identifier of the first application and the charging identifier allocated for the first application to the TDF entity, and the identifier of the first application is also required to be An application-assigned charging identifier is provided to the PCEF entity, so that the PCEF entity charges the uplink and downlink data packets of the first application based on the two information.
45、 PCEF实体向服务网关设备发送 IP-CAN承载建立请求消息，该 IP-CAN 承载建立请求消息包括第一应用的标识和为第一应用分配的计费标识。  The PCEF entity sends an IP-CAN bearer setup request message to the serving gateway device, where the IP-CAN bearer setup request message includes an identifier of the first application and a charging identifier assigned to the first application.
可选的， PCEF实体可以将第一应用的标识和为第一应用分配的计费标识 添加到 IP-CAN承载建立请求消息中的 PC0中， 提供给服务网关设备。 另外， 本实施例对第一应用的标识的实现不做限定。 举例说明， 如果需 要对新浪（Sina ) 网页的应用数据包计费， 那么可能将胃 . sina. com作为第 一应用的标识包含在 PC0中， 但不限于此。 Optionally, the PCEF entity may add the identifier of the first application and the charging identifier allocated for the first application to the PC0 in the IP-CAN bearer setup request message, and provide the information to the serving gateway device. In addition, this embodiment does not limit the implementation of the identifier of the first application. For example, if it is necessary to charge the application data packet of the Sina (Sina) webpage, it is possible to include the stomach. sina.com as the identifier of the first application in the PC0, but is not limited thereto.
46、服务网关设备接收到 IP-CAN承载建立请求消息后， 经过移动性管理 网元向 UE 透传第一应用的标识和为第一应用分配的计费标识， 例如可以向 After the service gateway device receives the IP-CAN bearer setup request message, the mobility management network element transparently transmits the identifier of the first application and the charging identifier allocated for the first application to the UE, for example,
UE透传 IP-CAN承载建立请求消息中的 PC0。 The UE transparently transmits PC0 in the IP-CAN bearer setup request message.
47、 UE收到第一应用的标识和为第一应用分配的计费标识后， 在第一应 用的上行数据包中添加该计费标识， 并将添加计费标识的第一应用的上行数 据包发送给 PCEF实体。  After receiving the identifier of the first application and the charging identifier allocated for the first application, the UE adds the charging identifier to the uplink data packet of the first application, and adds the uplink data of the first application of the charging identifier. The package is sent to the PCEF entity.
48、 PCEF实体收到 UE发送的携带有计费标识的上行数据包时， 对接收 到的数据包执行单独计费。  48. When receiving the uplink data packet carrying the charging identifier sent by the UE, the PCEF entity performs separate charging on the received data packet.
通过本实施例的方法， PCEF实体收到 UE发送的上行数据包后， 能够通 过其携带的计费标识获知该上行数据包属于需要进行计费的第一应用， 从而 实现在上行方向上对第一应用的单独计费。 另外， PCEF实体收到 TDF实体发 送的下行数据包后， 能够通过其携带的计费标识获知该下行数据包属于需要 进行计费的第一应用， 从而实现在下行方向上对第一应用的单独计费。另外， 本实施例提供的计费方法在 PCEF实体上实现，与现有技术中基于 SDF的计费 在同一设备上执行， 因此， 不存在重复计费造成的计费不准确的问题。  After receiving the uplink data packet sent by the UE, the PCEF entity can learn, by using the charging identifier carried by the PCEF, that the uplink data packet belongs to the first application that needs to be charged, thereby implementing the uplink application in the uplink direction. Separate billing for an application. In addition, after receiving the downlink data packet sent by the TDF entity, the PCEF entity can learn that the downlink data packet belongs to the first application that needs to be charged by using the charging identifier carried by the PCEF entity, thereby implementing a separate application for the first application in the downlink direction. fee. In addition, the charging method provided in this embodiment is implemented on the PCEF entity, and is performed on the same device as the SDF-based charging in the prior art. Therefore, there is no problem of inaccurate charging caused by repeated charging.
本发明提供的第二种计费方法主要针对在 PCEF实体执行基于 SDF粒度的 计费， 当数据包到达 TDF实体后， 由于 TDF实体可能对某些应用执行流控， 引起某些应用的数据包被丢弃而造成计费不准确的问题， 或者针对上下行 IP 地址相同的数据包打相同标识进行计费，但实际需要计费的可能仅是该 IP地 址的部分数据包造成该过量计费的问题而提出的。  The second charging method provided by the present invention is mainly for performing SDF granularity-based charging in a PCEF entity. When a data packet arrives at a TDF entity, the TDF entity may perform flow control on some applications, causing data packets of some applications. The problem that the accounting is inaccurate is discarded, or the same identifier is used for the data packets with the same uplink and downlink IP address for charging. However, the actual charging requirement may be only the partial data packet of the IP address causing the excessive charging. The question was raised.
第二种计费方法的主要思路是： PCEF实体对数据包执行基于 SDF粒度的 计费之后， 当数据包到达 TDF实体时， TDF实体根据 PCRF实体提供的 PCC规 则标识和 /或 SDF模板确定影响 PCEF实体基于 SDF粒度计费结果的第一应用 所属的 SDF和第一应用的数据包的流量，然后通过 PCRF实体将第一应用所属 的 SDF的标识和第一应用的数据包的流量发送给 PCEF实体， 以使所述 PCEF 实体根据第一应用所属的 SDF 的标识和第一应用的数据包的流量调整基于 SDF粒度的计费结果。 基于第二种计费方法的主要思路， 下面分别从 PCRF实体、 PCEF实体以 及 TDF实体的角度详细说明第二种计费方法的流程。 The main idea of the second charging method is: After the PCEF entity performs SDF granularity-based charging on the data packet, when the data packet arrives at the TDF entity, the TDF entity determines the influence according to the PCC rule identifier and/or the SDF template provided by the PCRF entity. The PCEF entity sends the traffic of the SDF to which the first application belongs and the traffic of the data packet of the first application to the PCEF by the PCRF entity, and then sends the traffic of the data packet of the first application to the PCEF by the PCRF entity. An entity, so that the PCEF entity adjusts the SDF granularity based charging result according to the identifier of the SDF to which the first application belongs and the traffic of the data packet of the first application.

下面从多网元交互的角度， 进一步对本发明提供的第二种计费方法的流 程进行详细描述。  The flow of the second charging method provided by the present invention is further described in detail from the perspective of multi-network element interaction.
图 5为本发明实施例提供的又一种计费方法的流程图。 如图 5所示， 所 述方法包括：  FIG. 5 is a flowchart of still another charging method according to an embodiment of the present invention. As shown in Figure 5, the method includes:
51、 PCRF实体向 TDF实体发送 TDF会话建立请求消息， 该 TDF会话建立 请求消息包括 PCC规则标识 （PCC rule id ) 和 /或 SDF模板。  51. The PCRF entity sends a TDF session establishment request message to the TDF entity, where the TDF session establishment request message includes a PCC rule id and/or an SDF template.
其中， PCC规则标识用于指示 PCC规则， 该 PCC规则包括很多信息， 用 于执行业务流控制以及计费规则等。 在本实施例中， 所述计费规则会指示具 体对哪个或哪些应用进行计费。 SDF模板就是一组五元组信息， 用于指示应 用流所走的承载， 通俗来说就是指示应用流应该走在哪个承载中。  The PCC rule identifier is used to indicate a PCC rule, and the PCC rule includes a lot of information, which is used to perform service flow control and charging rules. In this embodiment, the charging rule indicates which application or applications are billed. The SDF template is a set of quintuple information used to indicate the bearer of the application flow. In general, it indicates which bearer the application flow should go in.
52、 TDF实体向 PCRF实体发送 TDF会话建立响应消息。  52. The TDF entity sends a TDF session setup response message to the PCRF entity.
53、 当数据包到达 TDF实体时， TDF实体根据 PCC规则标识和 /或 SDF模 板， 确定第一应用所属的 SDF和所述第一应用的数据包的流量， 以便于 PCEF 实体根据第一应用所属的 SDF和第一应用的数据包的流量调整基于 SDF粒度 的计费结果。 When the data packet arrives at the TDF entity, the TDF entity determines, according to the PCC rule identifier and/or the SDF template, the traffic of the SDF to which the first application belongs and the data packet of the first application, so that the PCEF entity belongs according to the first application. SDF and traffic flow adjustment for the first application based on SDF granularity Billing result.
在本实施例中， TDF实体根据 PCC规则标识所指示的 PCC规则和 /或 SDF 模板， 可以获知需要计费的第一应用所属的 SDF。 第一应用是指影响 PCEF实 体基于 SDF粒度的计费结果的应用， 例如可以是 TDF实体因执行流控而丢弃 的数据包所属的应用， 或者是 TDF实体确定的需要单独计费的应用， 还可以 是 TDF实体确定的不需要单独计费的应用。  In this embodiment, the TDF entity can identify the SDF to which the first application that needs to be charged belongs according to the PCC rule and/or the SDF template indicated by the PCC rule. The first application is an application that affects the SDF granularity-based charging result of the PCEF entity, and may be, for example, an application to which the TDF entity discards the data packet discarded by the flow control, or an application determined by the TDF entity that needs to be separately charged. It can be an application determined by the TDF entity that does not require separate billing.
具体的， 如果 TDF实体根据 PCC规则标识指示的 PCC规则， 确定要执行 基于应用的流控， 比如丢弃某应用的部分数据包， 那么 TDF实体可以根据该 应用的 IP地址等信息确定丢弃的数据包所属的 SDF; 此时， 丢弃数据包所属 的应用即为第一应用。  Specifically, if the TDF entity determines that the application-based flow control is to be performed according to the PCC rule indicated by the PCC rule, for example, discarding part of the data packet of the application, the TDF entity may determine the discarded data packet according to the information such as the IP address of the application. The SDF to which it belongs; At this time, the application to which the dropped packet belongs is the first application.
如果 TDF实体根据 SDF模板探测到并不需要对具有相同 IP地址信息的所 有数据包进行计费时， 从具有相同 IP地址信息的所有数据包中， 确定实际需 要计费的应用的数据包， 并确定需要计费的应用所属的 SDF; 此时， 实际需 要计费的应用即为所述第一应用。 或者， TDF实体还可以从具有相同 IP地址 信息的所有数据包， 确定出不属于实际需要计费的应用的数据包， 并确定这 些不需要计费的数据包所属的 SDF; 此时， 所述不需要计费的数据包所属的 应用即为第一应用。  If the TDF entity detects from the SDF template that it is not required to charge all data packets having the same IP address information, the data packets of the application that actually need to be charged are determined from all the data packets having the same IP address information, and The SDF to which the application that needs to be charged belongs is determined. At this time, the application that actually needs to be charged is the first application. Alternatively, the TDF entity may also determine, from all the data packets having the same IP address information, the data packets that are not in the application that need to be charged, and determine the SDF to which the data packets that do not need to be charged belong; The application to which the data packet that does not need to be charged belongs is the first application.
54、 TDF实体将第一应用所属的 SDF的标识和第一应用的数据包的流量 发送给 PCRF实体。  54. The TDF entity sends the identifier of the SDF to which the first application belongs and the traffic of the data packet of the first application to the PCRF entity.
55、 PCRF实体向 PCEF实体发送 IP-CAN会话修改请求消息， 所述 IP-CAN 会话修改请求消息包括第一应用所属的 SDF的标识和第一应用的数据包的流  55. The PCRF entity sends an IP-CAN session modification request message to the PCEF entity, where the IP-CAN session modification request message includes the identifier of the SDF to which the first application belongs and the flow of the data packet of the first application.
56、 PCEF实体根据第一应用所属的 SDF的标识和第一应用的数据包的流 量， 对第一应用所属的 SDF的计费结果进行调整， 以达到准确计费的目的。 The PCEF entity adjusts the charging result of the SDF to which the first application belongs according to the identifier of the SDF to which the first application belongs and the traffic of the data packet of the first application, so as to achieve accurate charging.
在本实施例中， 在 PCEF实体执行基于 SDF粒度的计费后， TDF实体对该 数据流执行检测， 通过将执行流控而丢弃的数据包所属 SDF的标识以及丢弃 的数据包的流量通过 PCRF实体通知 PCEF实体， 使得 PCEF实体对基于该 SDF 的计费结果进行调整， 或者将具有相同 IP地址信息的数据中， 实际需要计费 的应用所属的 SDF和流量， 或不需要计费的应用所属的 SDF和流量经过 PCRF 实体发送给 PCEF实体， 以便于 PCEF实体对基于 SDF粒度的计费结果进行调 整， 从而达到准确计费的目的， 解决计费不准确的问题。 In this embodiment, after the PCEF entity performs the SDF granularity-based charging, the TDF entity performs detection on the data flow, and the traffic of the SDF that belongs to the data packet that is discarded by performing the flow control and the traffic of the discarded data packet are passed through the PCRF. The entity notifies the PCEF entity, so that the PCEF entity adjusts the charging result based on the SDF, or the data that has the same IP address information, the SDF and the traffic to which the application that actually needs to be charged belongs, or the application that does not need to be charged The SDF and traffic are sent to the PCEF entity through the PCRF entity, so that the PCEF entity adjusts the SDF granularity based charging result. In order to achieve accurate billing, the problem of inaccurate billing is solved.
本发明提供的第三种计费方法主要针对在 PCEF实体执行基于 SDF粒度的 计费， 当数据包到达 TDF实体后， 由于 TDF实体可能对某些应用执行流控， 引起某些应用的数据包被丢弃而造成计费不准确的问题， 或者针对上下行 IP 地址相同的数据包打相同标识进行计费，但实际需要计费的可能仅是该 IP地 址的部分数据包造成该过量计费的问题而提出的。  The third charging method provided by the present invention is mainly for performing SDF granularity-based charging in a PCEF entity. When a data packet arrives at a TDF entity, the TDF entity may perform flow control on some applications, causing data packets of some applications. The problem that the accounting is inaccurate is discarded, or the same identifier is used for the data packets with the same uplink and downlink IP address for charging. However, the actual charging requirement may be only the partial data packet of the IP address causing the excessive charging. The question was raised.

After the PCEF entity performs SDF granularity-based charging on the data packet, when the data packet arrives at the TDF entity, the TDF entity determines the reflow data, and re-sends the reflow data to the PCEF entity, so that the PCEF entity is based on the The fee identifier determines the reflow data, and adjusts the SDF granularity based charging result according to the reflow data to achieve accurate charging. The reflow data refers to data that affects the charging result of the PCEF entity based on the SDF granularity.

下面从多网元交互的角度， 进一步对本发明提供的第三种计费方法的流 程进行详细描述。  The flow of the third charging method provided by the present invention is further described in detail from the perspective of multi-network element interaction.
图 6为本发明实施例提供的又一种计费方法的流程图。 如图 6所示， 所 述方法包括：  FIG. 6 is a flowchart of still another charging method according to an embodiment of the present invention. As shown in Figure 6, the method includes:
61、 PCEF实体接收服务网关设备发送的 IP-CAN承载建立请求消息。 61. The PCEF entity receives an IP-CAN bearer setup request message sent by the serving gateway device.
62、 PCEF实体向 PCRF实体发送 IP-CAN会话建立请求消息。 62. The PCEF entity sends an IP-CAN session establishment request message to the PCRF entity.
63、 PCRF实体确定需要分配给回流数据的计费标识。  63. The PCRF entity determines a charging identifier that needs to be assigned to the reflow data.
在此说明， 本实施例中的回流数据是指影响计费准确性， 用于供 PCEF实 体对基于 SDF粒度的计费结果进行调整的数据，是由 TDF实体返回给 PCEF实 体的， 例如可以是 TDF实体基于应用数据流进行计费后的数据， 或者是 TDF 实体执行流控而丢弃的数据。  It is noted that the reflow data in this embodiment refers to the data that affects the charging accuracy, and is used by the PCEF entity to adjust the SDF granularity-based charging result, which is returned by the TDF entity to the PCEF entity, for example, The TDF entity performs charging based on the application data stream, or data that is discarded by the TDF entity to perform flow control.
其中， PCRF实体为回流数据分配计费标识， 目的一是供 TDF实体标识回 流数据，二是使 PCEF实体基于计费标识从接收到的下行数据中识别出回流数 据。 PCRF实体分配给回流数据的计费标识可以是 DSCP值， 以便于在数据包 的 IP头中的 DSCP位采用相应的值标识该回流数据。  The PCRF entity allocates a charging identifier for the reflow data, and the purpose is to enable the TDF entity to identify the reflow data, and the second is to enable the PCEF entity to identify the reflow data from the received downlink data based on the charging identifier. The charging identifier assigned by the PCRF entity to the reflow data may be a DSCP value so that the DSCP bit in the IP header of the packet identifies the reflow data with a corresponding value.
64、 PCRF实体向 TDF实体发送 TDF会话建立请求消息， 该 TDF会话建立 请求消息包括分配给回流数据的计费标识， 例如 DSCP值。  64. The PCRF entity sends a TDF session establishment request message to the TDF entity, where the TDF session establishment request message includes a charging identifier assigned to the reflow data, such as a DSCP value.
65、 TDF实体向 PCRF实体发送 TDF会话建立响应消息。  65. The TDF entity sends a TDF session setup response message to the PCRF entity.
66、 PCRF实体向 PCEF实体发送 IP-CAN会话建立响应消息， 该 IP-CAN 会话建立响应消息包括分配给回流数据的计费标识，例如 DSCP值。至此， PCRF 实体与 TDF实体和 PCEF实体相配合， 为回流数据分配了计费标识， 并分别提 供给了 TDF实体和 PCEF实体， 以便于后续 TDF实体和 PCEF实体基于该回流 数据的计费标识， 进行更加准确的计费操作。 66. The PCRF entity sends an IP-CAN session establishment response message to the PCEF entity, the IP-CAN The session setup response message includes a charging identifier assigned to the reflow data, such as a DSCP value. At this point, the PCRF entity cooperates with the TDF entity and the PCEF entity to allocate a charging identifier for the reflow data, and provides the TDF entity and the PCEF entity respectively, so that the subsequent TDF entity and the PCEF entity are based on the charging identifier of the reflow data. Perform more accurate billing operations.
67、 TDF实体接收到上行数据包后， 确定回流数据， 例如 TDF实体可以 执行流控策略， 确定需要丢弃的上行数据包作为回流数据， 或者 TDF实体将 基于应用数据流计费的应用的上行数据包作为回流数据。  67. After receiving the uplink data packet, the TDF entity determines the reflow data. For example, the TDF entity may perform a flow control policy, determine the uplink data packet to be discarded as the reflow data, or the uplink data of the application that the TDF entity will charge based on the application data flow. The package acts as reflux data.
68、 TDF实体将所确定的回流数据转发给 PCEF实体， 并在回流数据中包 含分配给回流数据的计费标识， 例如 DSCP值等， 以便于 PCEF实体接收到回 流数据时， 能够识别出接收到的是回流数据， 即是 TDF实体丢弃的上行数据 包或 TDF实体基于应用数据流进行计费的上行数据包。  68. The TDF entity forwards the determined reflow data to the PCEF entity, and includes a charging identifier, such as a DSCP value, allocated to the reflow data in the reflow data, so that the PCEF entity can recognize the received data when receiving the reflow data. The reflow data is the uplink data packet discarded by the TDF entity or the uplink data packet that the TDF entity performs charging based on the application data flow.
具体的， TDF实体可以将回流数据的外层 IP头的 IP地址等信息进行反 转， 然后转发给 PCEF实体。  Specifically, the TDF entity may reverse information such as the IP address of the outer IP header of the reflow data, and then forward the information to the PCEF entity.
69、 PCEF实体收到回流数据后， 根据回流数据中的计费标识， 确定接收 到的是回流数据， 则根据回流数据包内层的 IP信息， 例如 IP地址等确定该 回流数据所属的 SDF, 并调整对该 SDF的计费结果， 以便于准确计费。  69. After receiving the reflow data, the PCEF entity determines, according to the charging identifier in the reflow data, that the reflow data is received, determining the SDF to which the reflow data belongs according to the IP information of the inner layer of the reflow packet, such as an IP address. And adjust the billing result for the SDF to facilitate accurate billing.
具体的， PPCEF实体可以统计回流数据的流量， 并从回流数据所属的 SDF 的计费结果中扣除因该回流数据的流量产生的费用， 以达到准确计费的目的。  Specifically, the PPCEF entity can count the traffic of the reflow data, and deduct the fee generated by the traffic of the reflow data from the charging result of the SDF to which the reflow data belongs, so as to achieve accurate charging.
在本实施例中， 预先协商回流数据对应的计费标识， 并定义该计费标识 用于指示 PCEF实体对基于 SDF粒度的计费结果进行调整， 则在 PCEF实体基 于 SDF粒度计费完成后， 数据包到达 TDF实体， TDF实体执行基于应用的流 控或基于应用数据流的计费等操作后， 确定操作的数据包作为回流数据并在 其中携带计费标识， 然后转发给 PCEF实体， 以便于 PCEF实体基于回流数据 中的计费标识确定回流数据， 然后根据回流数据所属的 SDF并调整该 SDF的 计费结果， 达到准确计费的目的。  In this embodiment, the charging identifier corresponding to the reflow data is pre-negotiated, and the charging identifier is used to indicate that the PCEF entity adjusts the SDF granularity-based charging result, after the PCEF entity completes the SDF granularity charging, The data packet arrives at the TDF entity. After the TDF entity performs application-based flow control or application data flow-based charging, the data packet of the operation is determined as the reflow data and carries the charging identifier therein, and then forwarded to the PCEF entity, so as to facilitate The PCEF entity determines the reflow data based on the charging identifier in the reflow data, and then adjusts the charging result of the SDF according to the SDF to which the reflow data belongs, so as to achieve accurate charging.
在此说明， 在图 6所示实施例中， 以上行数据包为例进行了说明， 对于 下行数据包可以采用类似图 6所示实施例的方式进行处理。  Here, in the embodiment shown in Fig. 6, the above data packet is described as an example, and the downlink data packet can be processed in a manner similar to the embodiment shown in Fig. 6.
