Description

在多媒体广播 /组播业务中计费的方法、装置及*** 技术领域 Method, device and system for charging in multimedia broadcast/multicast service

本发明涉及通信领域的多媒体广播 /组播业务，尤其涉及在多媒体广播 / 组播业务中计费的方法、装置及***。背景技术 The present invention relates to multimedia broadcast/multicast services in the field of communications, and more particularly to a method, apparatus and system for charging in multimedia broadcast/multicast services. Background technique

随着第三代移动通信技术的发展，第三代移动通信可以提供比第二代移动通信更高数据速率的服务，从而支持多种业务形式。随着手机的集成度越来越高，手机的信息处理能力也越来越强，可以提供一定分辨率与色彩的彩色屏幕、摄像头；随着新的无线接入网络技术的出现，可以提供足够宽的数据无线传输带宽。在这种条件下，与视频相关的各种应用就艮自然的出现在手机上，比如多媒体短消息业务、分组（PS )域视频流业务、可视电话业务、多媒体广播 /组播等服务。多媒体广播 /组播（MBMS )业务的特点是：该业务可以同时给无线网络中订阅了该业务的用户进行发送。比如说天气预报、新闻短片、体育比赛集锦等等。利用这些业务同时发送的特点，能够更为有效地利用优先的空中接口资源 , 提供更高的***容量。 With the development of third generation mobile communication technologies, third generation mobile communication can provide higher data rate services than second generation mobile communication, thereby supporting multiple service forms. With the increasing integration of mobile phones, the information processing capabilities of mobile phones are becoming stronger and stronger, and color screens and cameras with a certain resolution and color can be provided. With the advent of new wireless access network technologies, sufficient Wide data wireless transmission bandwidth. Under such conditions, various applications related to video naturally appear on mobile phones, such as multimedia short message service, packet (PS) domain video stream service, videophone service, multimedia broadcast/multicast, and the like. The characteristics of the Multimedia Broadcast/Multicast (MBMS) service are: The service can be simultaneously sent to users who subscribe to the service in the wireless network. For example, weather forecasts, news clips, sports highlights, and more. By utilizing the simultaneous transmission of these services, it is possible to more efficiently utilize the priority air interface resources and provide higher system capacity.

广播 /组播业务中，对于一个中间节点而言，无论其下游包含多少个期待接收数据的节点，其上游节点总是向该中间节点发送一份数据；该中间节点收到数据后，根据其下游期待接收数据的节点数量复制该数据，并向其下游各期待接收该数据的节点分发该数据，这样，组播 /广播业务数据传输树的每一条分支都只有一份数据进行传输，占用一份传输资源，根节点与其下游节点的数据传输也是如此。组播业务和广播业务的区别点仅在于：组播业务只向订阅了某些信息的用户发送相应信息，广播业务则向无线网络中的所有用户发送信息。由此可知，通过组播 /广播业务同时向大量用户提供相同信息，能够极大地节省网络资源。 In a broadcast/multicast service, for an intermediate node, regardless of how many nodes that are expected to receive data downstream, the upstream node always sends a data to the intermediate node; after receiving the data, the intermediate node according to the The number of nodes that are expected to receive data downstream copies the data, and distributes the data to the nodes that are expected to receive the data downstream. Thus, each branch of the multicast/broadcast service data transmission tree has only one data for transmission, occupying one. The transmission resource, as well as the data transmission of the root node and its downstream nodes. The difference between multicast service and broadcast service is only that: multicast service only sends corresponding information to users who subscribe to certain information, and broadcast service sends information to all users in the wireless network. It can be seen that the multicast/broadcast service provides the same information to a large number of users at the same time, which can greatly save network resources.

如图 1所示， 3GPP中支持广播 /组播业务的无线网络结构为广播 /组播业务中心（ Broadcast/Multicast - Service Centre, BM-SC ), BM-SC通过 Gmb接口或 Gi接口与关口 GPRS支持节点（Gateway GPRS Support Node, GGSN ) 相连，一个 BM-SC可与多个 GGSN相连； GGSN通过 Gn/Gp接口与服务 GPRS 支持节点（Serving GPRS Support Node, SGSN )相连，一个 GGSN可与多个 SGSN相连； SGSN可通过 Iu接口与通用移动通信***（UMTS )陆地无线接入网（UTRAN )相连，然后 UTRAN通过 Uu接口与用户终端（UE )相连， SGSN也可通过 Iu/Gb接口与全球移动通信*** （GSM )增强无线接入网 ( GERAN )相连，然后 GERAN通过 Uu接口与 UE相连。其中， GGSN和 SGSN属于无线网络中核心网（CN ) 内的节点。 As shown in Figure 1, the wireless network structure supporting broadcast/multicast services in 3GPP is the Broadcast/Multicast Service Center (BM-SC), and the BM-SC is connected through the Gmb. The port or the Gi interface is connected to the Gateway GPRS Support Node (GGSN), and one BM-SC can be connected to multiple GGSNs; the GGSN is connected to the Serving GPRS Support Node (SGSN) through the Gn/Gp interface. A GGSN can be connected to multiple SGSNs; the SGSN can be connected to the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN) through the Iu interface, and then the UTRAN is connected to the user terminal (UE) through the Uu interface, and the SGSN can also pass The Iu/Gb interface is connected to the Global System for Mobile Communications (GSM) Enhanced Radio Access Network (GERAN), which then connects to the UE via the Uu interface. Among them, the GGSN and the SGSN belong to nodes in the core network (CN) in the wireless network.

广播 /组播业务中心为 MBMS用户业务的发送提供功能。可以作为一个在公共路地移动网 PLMN中用于 MBMS内容传输，授权和发起 MBMS承载业务的接入点，并且可以用于调度和发送 MBMS传输。 The Broadcast/Multicast Service Center provides functions for the transmission of MBMS user services. It can be used as an access point for MBMS content transmission, authorization and initiation of MBMS bearer services in the public land mobile network PLMN, and can be used for scheduling and transmitting MBMS transmissions.

图 2为广播 /组播业务的离线计费架构图，在广播 /组播业务的离线计费中， BM-SC产生计费事件，将计费数据通过 Rf接口传送给计费数据功能（ CDF ); CDF再通过 Ga接口将计费数据记录（CDR )传送给计费网关功能（CGF ); CGF再通过 Bmb接口将计费数据文件 ( CDR files )发送给计费域（Billing Domain, 或称计费中心）。 2 is an offline charging architecture diagram of a broadcast/multicast service. In the offline charging of a broadcast/multicast service, the BM-SC generates a charging event, and transmits the charging data to the charging data function through the Rf interface (CDF). The CDF then transmits the charging data record (CDR) to the charging gateway function (CGF) through the Ga interface; the CGF then sends the CDR files to the charging domain via the Bmb interface (Billing Domain, or Billing Center).

现有的 MBMS业务在基于流量的计费上，采用的是传统的计费方式，即针对上下行流量都进行计费。 The existing MBMS service uses the traditional charging method for traffic-based charging, that is, charging for both uplink and downlink traffic.

从组播 /广播业务的特点可知，所有的数据业务流量全部通过下行传送，上行流量仅有信令数据。发明人在实施现有技术中发现，采用传统的对上下行都进行计费的方式对 MBMS业务计费时，在计费话单中提供没有意义的上行信令交互流量数据，使运营商与终端用户以及运营商与运营商之间的结算产生困惑，并容易造成对用户的计费错误；另外，由于上行业务数据仅为信令数据，也会占用***资源和加重***的负荷。发明内容 According to the characteristics of the multicast/broadcast service, all data traffic is transmitted through the downlink, and the uplink traffic only has signaling data. In the implementation of the prior art, the inventor has found that when the MBMS service is charged in the manner of charging the uplink and the downlink, the indirect signaling interaction traffic data is provided in the charging bill, so that the operator and the operator The settlement between the end user and the operator and the operator is confusing, and it is easy to cause charging error to the user. In addition, since the uplink service data is only signaling data, it also occupies system resources and increases the load of the system. Summary of the invention

组播 /广播业务的特点是：上游节点总是向中间节点发送业务数据；中间节点收到业务数据后，根据其下游期待接收数据的节点数量进行复制，并向其下游各期待接收该数据的节点分发该数据，这样，组播 /广播业务数据传输树的每一条分支都只有一份数据进行传输，占用一份传输资源，根节点与其下游节点的数据传输也是如此。 The characteristics of the multicast/broadcast service are: The upstream node always sends the service data to the intermediate node; after receiving the service data, the intermediate node replicates according to the number of nodes that the downstream party expects to receive data, and expects to receive the data to the downstream thereof. The node distributes the data, so that each branch of the multicast/broadcast service data transmission tree has only one piece of data for transmission, consuming one transmission resource, and the same is true for the data transmission of the root node and its downstream nodes.

由于组播 /广播业务中所有的数据业务流量全部通过下行传送，上行流量仅有信令数据。本实施例在基于流量计费方式的 MBMS业务中，广播 /组播业务中心 BM-SC触发计费并将业务数据存储器增加到话单中时，所述业务数据存储器中用于计费的数据业务流量仅为下行数据业务流量，即广播 /组播业务中心 BM-SC仅针对下行数据业务流量触发计费。 Since all data traffic in the multicast/broadcast service is transmitted through the downlink, the uplink traffic has only signaling data. In this embodiment, in the MBMS service based on the flow rate method, when the broadcast/multicast service center BM-SC triggers charging and adds the service data storage to the bill, the data used in the service data storage is used for charging. The traffic is only downlink data traffic, that is, the broadcast/multicast service center BM-SC only triggers charging for downlink data traffic.

BM-SC仅针对下行数据业务流量触发计费可以有多种方式，例如，在一个具体实例中， BM-SC增加到话单中的业务数据存储器仅为下行业务数据存储器，即不将上行业务数据存储器增加到话单中。在另一个具体实例中， BM-SC将上、下行业务数据存储器增加到话单，并且将上行业务数据存储器中的业务数据流量置零。由于仅针对下行数据业务流量计费，因此可由 BM-SC 关闭上行数据业务流量统计计数器（使上行业务数据存储器中的业务数据流量为零），以节约***资源。 The BM-SC can only trigger the charging for the downlink data service traffic. For example, in a specific example, the service data storage added to the CDR by the BM-SC is only the downlink service data storage, that is, the uplink service is not used. The data memory is added to the bill. In another embodiment, the BM-SC adds the upstream and downstream traffic data stores to the CDRs and zeros the traffic data traffic in the upstream traffic data store. Since the downlink data traffic is only charged for the downlink data service, the BM-SC can be used to close the uplink data traffic statistics counter (so that the traffic data in the uplink service data storage is zero) to save system resources.

为了保证***的兼容性 , BM-SC在将多***共用的业务数据列表（ List of Service Data )增加到话单中时，将业务数据列表中的上行数据业务流量置零。 In order to ensure the compatibility of the system, the BM-SC sets the uplink data traffic in the service data list to zero when the list of service data shared by multiple systems is added to the bill.

参阅图 3所示，本实施例中 3GPP网络的离线计费***包括 BM-SC, 通过 Rf接口与 BM-SC连接的计费数据功能 CDF实体，通过 Ga接口与 CDF实体连接的 CGF实体，以及通过 Bx接口与 CGF实体连接的计费域 BD。 Referring to FIG. 3, the offline charging system of the 3GPP network in this embodiment includes a BM-SC, a charging data function CDF entity connected to the BM-SC through the Rf interface, a CGF entity connected to the CDF entity through the Ga interface, and A billing domain BD connected to a CGF entity through a Bx interface.

BM-SC仅触发下行数据业务流量计费，并将业务数据存储器增加到话单中；计费数据功能实体用于根据所述话单形成话单记录；计费网关实体用于根据所述话单记录形成话单文件（CDR files, 或称计费数据文件）；计费中心按所述话单文件对用户计费。 The BM-SC only triggers the downlink data service flow rate, and adds the service data storage to the bill; the billing data function entity is used to form the bill record according to the bill; the billing gateway entity is used for Forming a CDR file (or a CDR file) according to the CDR record; the billing center charges the user according to the CDR file.

参阅图 4所示，本实施例中， BM-SC触发计费的流程如下（图中省略了 CGF和计费域的后续处理过程 ): Referring to FIG. 4, in this embodiment, the BM-SC triggers the charging process as follows (the subsequent processing of the CGF and the charging domain is omitted in the figure):

步骤 400、 BM-SC向 GGSN发送会话开始请求（ Session Start Request )。步骤 410、 GGSN进行相应的处理后，向 BM-SC返回会话开始响应消息 ( Session Start Response )。步骤 420、 BM-SC向 CDF发送计费请求（ Accounting Request ( start ) ), 并且 BM-SC仅将业务数据存储器中的下行业务数据存储器增加到话单中 , 即不将上行业务数据存储器增加到话单中。 Step 400: The BM-SC sends a Session Start Request to the GGSN. Step 410: After performing corresponding processing, the GGSN returns a session start response message (Session Start Response) to the BM-SC. Step 420: The BM-SC sends an Accounting Request (start) to the CDF, and the BM-SC adds only the downlink service data storage in the service data storage to the CDR, that is, does not add the uplink service data storage to In the bill.

由于不使用上行数据业务流量，因此在 BM-SC开始统计数据业务流量时，可以关闭上行数据业务流量统计计数器，以节约***资源。 Since the uplink data service traffic is not used, when the BM-SC starts to count the data traffic, the uplink data traffic statistics counter can be turned off to save system resources.

步骤 430、 CDF向 BM-SC返回计费应答 ( Accounting Answer )„ 步骤 440、 GGSN 向 SGSN发送会话开始请求（ MBMS Session Start Request )。 Step 430: The CDF returns an Accounting Answer to the BM-SC. Step 440: The GGSN sends a MBMS Session Start Request to the SGSN.

步骤 450、 SGSN 向 GGSN发送会话开始响应（ MBMS Session Start Response ), 开始 MBMS业务。 Step 450: The SGSN sends a MBMS Session Start Response to the GGSN to start the MBMS service.

步骤 460、 MBMS用户终端上下文修改, BM-SC向 CDF发送计费请求（更新）（Accounting Request ), 其中 BM-SC将下行业务数据存储器增加到话单中，并且不包含上行业务数据存储器。 Step 460: The MBMS user terminal context is modified, and the BM-SC sends an Accounting Request (Update) to the CDF, where the BM-SC adds the downlink service data storage to the bill, and does not include the uplink service data storage.

步骤 470、 CDF向 BM-SC返回计费响应。 Step 470: The CDF returns a charging response to the BM-SC.

步骤 480、费率时间变化， BM-SC 向 CDF发送计费请求（Accounting Step 480, the rate time changes, and the BM-SC sends a charging request to the CDF (Accounting)

Request ), 其中 BM-SC将一系列业务数据列表增加到话单中，并且将业务数据存储器中上行数据流量置为 0。 Request ), where the BM-SC adds a list of service data to the bill and sets the upstream data traffic in the service data store to zero.

步骤 490、 CDF向 BM-SC返回计费响应。 Step 490: The CDF returns a charging response to the BM-SC.

上述流程仅用于说明本实施例中 BM-SC触发的计费处理过程，其中的计费请求并不意味着连续进行。如，在对某个 MBMS业务的计费过程中，可能没有步骤 480和步骤 490，即在计费过程中没有费率变化。在 CDF接收到计费请求后，通过 Ga接口将计费数据记录 CDR传送给计费网关功能 CGF, CGF 通过 Bmb接口将话单文件 ( CDR files )发送给计费域 BD, 由计费域 BD根据计费数据文件进行计费。 The foregoing process is only used to describe the charging process triggered by the BM-SC in this embodiment, and the charging request does not mean continuous. For example, in the charging process for a certain MBMS service, there may be no steps 480 and 490, that is, there is no rate change in the charging process. After receiving the charging request, the CDF transmits the CDR of the charging data record to the charging gateway function CGF through the Ga interface, and the CGF sends the CDR files to the charging domain BD through the Bmb interface, and the charging domain BD is used. Billing is performed based on the billing data file.

对于 BM-SC将业务数据存储器增加到话单时，将上行业务数据存储器置零的方式，与上述处理流程的不同之处主要在于，在步骤 420和步骤 460中， BM-SC将上行和下行业务数据存储器增加到话单中，但将上行业务数据存储器置零，其余处理同理，不再赘述。 When the BM-SC adds the service data storage to the CDR, the way to set the uplink service data storage to zero is different from the above processing flow mainly in that, in steps 420 and 460, the BM-SC will go up and down. Service data storage is added to the bill, but the uplink service data is stored. The device is set to zero, and the rest of the processing is the same, and will not be described again.

相应的，本实施例中的一种多媒体广播 /组播业务中心包括：接收模块、发送模块和处理模块；所述发送模块发送会话开始请求消息，所述接收模块接收会话开始响应消息，所述处理模块在接收到会话开始响应消息时，以及在业务进行过程中触发计费并将业务数据存储器增加到话单中，其中，所述业务数据存储器中用于计费的数据业务流量仅为下行数据业务流量。 Correspondingly, a multimedia broadcast/multicast service center in this embodiment includes: a receiving module, a sending module, and a processing module; the sending module sends a session start request message, and the receiving module receives a session start response message, where The processing module receives the session start response message, and triggers the charging in the process of the service, and adds the service data storage to the CDR. The data service traffic used for charging in the service data storage is only the downlink. Data traffic.

本实施例基于上述对 MBMS计费过程中，仅针对下行数据业务流量计费，即只有下行数据业务流量才会产生实际的话费，在触发话单内容增加时，不对上行数据业务流量进行话单触发，因而能够避免对用户的收费错误，提高用户满意度。另外，为了保证***的兼容性，对多***共用的业务数据列表 ( List of Service Data )，将不必要的上行数据业务流量统计计数器关闭或计数结果置零，达到既减少***复杂性、节约网络资源，同时又保证***兼容性的目的。 In this embodiment, based on the foregoing MBMS charging process, only the downlink data service flow rate is charged, that is, only the downlink data service traffic will generate the actual call charge, and when the triggered bill content is increased, the CDR of the uplink data service traffic is not performed. Triggering, thus avoiding charging errors to users and improving user satisfaction. In addition, in order to ensure the compatibility of the system, the list of service data shared by multiple systems is used to turn off unnecessary uplink data traffic statistics counters or zero the counting result, thereby reducing system complexity and saving network. Resources, while ensuring system compatibility.
