  • TECHNICAL FIELD The present invention relates to communication technologies, and more particularly to a method and system for charging.
  • BACKGROUND Currently, a WCDMA (Wideband Code Division Multiple Access) mobile communication system supports charging for voice calls and various types of data calls (including multimedia calls), and there are two types of charging methods for calls: offline charging mode and online charging. the way.
  • WCDMA Wideband Code Division Multiple Access
  • the offline charging of the call means that when the user initiates the call, the office through which the call passes each generates a bill (the calling end office has a mobile originating bill, and the called end office has a mobile terminated bill, the tandem office).
  • the gateway has access gateway bills, roaming bills, etc.).
  • the bills record information such as service type, call origination time and call duration. The operators generate these bills according to the packages. It realizes billing settlement between users and networks and between networks and networks after the event.
  • the following table shows the mobile originating bills.
  • the CDR is recorded with the caller identification information, the called identification information, the service type information of the service originally performed by the call, and the related information of the service change that may occur in the call.
  • time information for different phases of the call is used to record the specific situation of the call, and the operator can perform billing settlement for the user accordingly.
  • the level of detail of this information determines the accuracy of the operator's billing.
  • Online charging usually refers to intelligent prepaid services, which are characterized by users being charged immediately while conducting business.
  • the process is: when the user initiates the call, the SSP (Service Switching Point) triggers the call to the SCP (Service Control Point), the SCP performs call control on the SSP, and gives parameter information such as how long the call is allowed to be performed, and the SSP is in the call.
  • the SCP reports the relevant billing information such as the actual call duration.
  • the SCP can calculate the rate according to the operator's rate.
  • the SCP can re-submit a new command to the SSP, including the length of time allowed for the next call. Start billing for a new segment of the call until the user removes the call or the balance is exhausted.
  • Step 1-7 When the user initiates the call, the SSP reports the information of the initiated service type to the SCP through the IDP (Initial Detection Point) message, and the SCP calculates the allowable call of the user according to the user balance, the rate, and the like. The duration is then given to the SSP with the length of the allowable call as the maximum duration allowed for the call. At this time, the call is connected and the user starts the call.
  • IDP Initial Detection Point
  • Step 8 When the duration of the call reaches the maximum allowed time or the service is changed, the SSP reports the actual duration of the call to the SCP.
  • Step 9-14 The SCP determines whether the balance of the user is still allowed to continue the call. If yes, the new allowed call duration is extended, the new service is continued, until the call is disconnected or the allowed call duration is reached, and the SSP reports the last call to the SCP. The actual call duration, the SCP will charge the fee, otherwise, the process ends.

计费的方法和系统
技术领域 本发明涉及一种通信技术, 尤其涉及计费的方法和系统。 背景技术 目前, WCDMA (宽带码分多址)移动通讯系统支持语音呼叫、 各类数 据呼叫 (包括多媒体呼叫) 的计费, 对呼叫的计费方式有两种: 离线计费方 式和在线计费方式。
对呼叫的离线计费指的是, 当用户发起呼叫时, 呼叫所经过的局各自产 生话单(主叫端局有移动始发话单, 被叫端局有移动终结话单, 汇接局有汇 接话单, 关口局有出入关口局话单、 漫游话单, 等等) , 话单中记录有业务 类型、 呼叫发起时间和呼叫时长等信息, 运营商根据各局产生的这些话单, 实现在事后进行用户与网络间以及网络与网络间的计费结算。
下表示出了移动始发话单。
Figure imgf000003_0001
由上表可以看出, 话单中记录有主叫标识信息、 被叫标识信息、 呼叫最 初进行的业务的业务类型信息、 呼叫中可能发生的业务更改的相关信息, 以 ,
及呼叫的不同阶段的时间信息。 这些信息用于对呼叫的具体情况进行记录, 运营商可据此对用户进行计费结算。 这些信息的详细程度决定了运营商计费 的精确程度。
在线计费通常是指智能预付费业务, 其特点是用户在进行业务的同时被 即时计费。 其过程是: 用户在发起呼叫时, 由 SSP (业务交换点)将呼叫触发 到 SCP (业务控制点) , SCP对 SSP进行呼叫控制, 并下达允许呼叫进行多长 时间等参数信息 , SSP在呼叫时长到达所允许的时长时或用户提前结束呼叫结 束时, 向 SCP报告计费实际通话时长等相关计费信息, SCP掌握了用户的实际 通话时长后, 便能根据运营商制订的费率等信息对用户进行实时计费, 然后, 对于用户的余额尚足并且用户尚未拆除呼叫的情况, SCP可以重新向 SSP下达 新的命令, 包含下一段呼叫允许进行的时长。 开始新一段呼叫的计费, 直到 用户拆除呼叫或余额耗尽为止。
如图 1所示, 下面描述在线计费的过程。
步骤 1-7、 用户在发起呼叫时, SSP通过 IDP ( Initial Detect Point, 初始检 测点)消息向 SCP报告发起的业务类型等信息, SCP根据用户余额、 费率等信 息计算该用户可允许通话的时长, 然后以可允许通话的时长为参数下达给 SSP, 作为本段呼叫允许的最大时长, 这时呼叫接通, 用户开始通话。
步骤 8、 当用户通话时长到达所允许的最大时长或者更换业务时, SSP向 SCP报告实际的通话时长。
步骤 9-14、 SCP判断用户的余额是否还允许其继续通话, 若是, 下达新的 允许通话时长, 继续新的业务, 直至呼叫拆线或达到允许的通话时长, SSP向 SCP报告最后一段呼叫的实际通话时长, SCP对其进行扣费处理, 否则, 结束 本过程。
计费通知业务 (AOC):此业务可以将呼叫的计费信息实时地通知应付费的 客户, 也是在线计费所采用的技术之一。
移动电路域(CS DOMAIN )可视电话业务是第三代移动通信系统中的一 项重要业务, 是第三代移动通信区别于第二代的标志性业务之一。 这种业务 _
使得用户在进行语音通话的同时, 还可以看到对方的图像, 是一项有重要实 际应用价值的业务。
WCDMA第三代移动通信系统提供了一种称作 Multimedia call (多媒体呼 叫) 的业务, 这种业务可以在用户间建立语音流、 视频流或数据流通道。 可 以被用来完成可视电话功能。
该 Multimedia call的建立分为两个阶段: 第一阶段是按数据业务的方式完 成呼叫的接续以及在用户间建立承载业务通道, 第二阶段, 在应答后, 用户 通过终端在承载业务通道中以带内的方式建立媒体流的信令交互, 确定要建 立的语音、 视频和(或)数据媒体流, 从而建立完成多媒体呼叫。 由于第二 阶段建立媒体流的操作完全在带内进行, 相关信令未经过 MSC服务器(移动 交换中心服务器) , 因此 MSC服务器对媒体流通道的建立情况完全不了解, 不知道用户具体在进行语音、 视频或数据中哪些媒体类型的通讯。 因此, 使 得系统无法对视频通信这一类业务进行计费。
另外, 在现有技术中, 可视电话业务不能通过带外方式建立, 因此, 系 统对可视电话这一类业务的计费问题也就无从谈起, 然而, 由于可视电话业 务的重要性, 识別可视电话业务进行计费将为运营商的经营活动提供更多的 便利。 发明内容

本发明实施例公开了一种计费方法, 可实现包括可视电话的计费。
为了更好地理解本发明实施例, 首先介绍如何识别可视电话呼叫业务。 可视电话呼叫业务的分辨有两种方式, 一是通过扩展呼叫建立请求消息或业 务更改消息, 二是通过监测媒体流通道管理信息。 下面分别介绍分辨诸如可 视电话的业务类型的方法。
1、 由于呼叫的业务类型信息是通过在呼叫控制信令通道传送的呼叫建立 请求消息或业务更改消息中携带的, 因此, 可通过扩展呼叫建立请求消息或 业务更改消息, 使得呼叫建立请求消息或业务更改消息中业务类型包括可视 电话业务, 从而使 MSC服务器可直接从呼叫建立请求消息或业务更改消息获 得。
2、 MSC服务器也可通过监测媒体流通道管理信息来获得业务类型是否为 可视电话类型。
若媒体流通道管理信息是通过业务数据通道以带内的方式进行传输的, 由于 MSC服务器不能直接获得这些信息, 需要在呼叫建立过程中在 MGW (媒 体网关)分配复用端点资源, 将复用流中的流通道管理信息分离出来, 通过 媒体网关控制接口传递给 MSC服务器。
若媒体流通道管理信息是通过呼叫控制信令通道以带外方式进行传输 的, MSC服务器可直接从呼叫控制信令通道获得这些信息。
根据本发明实施例, 不仅限于区分可视电话呼叫, MSC还能够根据所建 立的逻辑通道类型或 (和) 不同类型的媒体流的条数来区分各种业务, 以实 现对各种不同业务的精确计费。 , , , · , 、, ^ t_ 为了买现对包括可枧电话呼叫业务的计费, 下面以可视电话呼叫业务为 例来说明计费过程, MSC或(和) SCP需要获得下述计费信息。
1、 可视电话发生的时间信息, 包括其发生的时刻、 结束的时刻(或 /和持 续的时长) 。
2、 对于通过媒体流的建立情况获得可视电话业务的情况, 需要记录各媒 体流在呼叫中存在的时间段。
3、 对于因业务更改而获得的可视电话业务的情况, 还需要获得业务更改 的发起者信息、 更改后的业务类型、 业务更改发生的时间、 新业务持续的时 长等;
确定业务更改操作的发起者的处理方法如下:
( 1 )对于主(被)叫方发起业务更改的情况: 该过程发生时, 主(被) 叫方会通知 MSC其待更改的业务类型, 该 MSC据此通知可记录业务更改的发 起方是主 (被) 叫方; 若存在下一跳 MSC, 该 MSC通知下一跳 MSC继续完成 业务更改时, 直至整个呼叫通路上的 MSC业务更改完毕为止, 所述的通知包 括业务更改发起者: 主(被) 叫方, 这样, 各个 MSC都能知道业务更改的发 起者是主(被)叫方, 所述的通知包括但不限于 Modify消息。
( 2 )对于网络中的某 MSC发起业务更改的情况, 由该 MSC向主叫方和被 叫方发起业务更改, 在发起业务更改时, 该 MSC通知下一跳 MSC (如果存在 的话)业务更改的发起者是网络(而非某方用户) , 直至整个呼叫通路上的 MSC业务更改完毕为止, 所述的通知包括业务更改发起者: 主(被) 叫方, 这样, 各个 MSC都能知道业务更改的发起者是主 (被) 叫方, 所述的通知包 括但不限于 Modify消息。
由于计费通常有两种方式: 离线计费和在线计费。 下面通过离线计費和 在线计费两种方式来描述本发明实施例的计费方法。
若采用离线计费方式时, 需要在离线计费话单中定义相应的域, 使其能 够记录上述信息。 当呼叫结束时, MSC生成相应话单, 计费系统据此进行计 费结算。 下面通过实施例 1来详细描述离线计费的方法。 、 , 、 , , 、 ,. . , 、, ·*
买施例 1一可枧电话呼叫的分辨及禹线计费
如图 2所示, 在本实施例中, 呼叫场景为: 用户 1向用户 2进行可视电话 呼叫。
第一过程、 用户 1 ( UE1 )向用户 2 ( UE2 )发起可视电话呼叫, 采用多媒 体呼叫的形式建立可视电话。 在发起呼叫时, UE1发给 MSC1的 SETUP消息中 指明该呼叫是多媒体呼叫, MSC1记录该业务类型和呼叫发起时间, 当呼叫应 答时记录应答时间。
第二过程、 用户 1与用户 2通过带内 H.245信令建立可视电话, MSC通过媒 体网关控制接口监测该过程, 当检测到成功建立语音和视频通道后, 表示建 立起可视电话呼叫, MSC在话单中记录业务更改的发生情况, 包括更改后的 业务类型, 新业务开始的时间, 持续的时长和发起者 (注: 本实施例是主叫 方向被叫方发起的媒体建立, 因此发起者为主叫方, 也可以由被叫方向主叫 方发起, 这样发起者就为被叫方) 。
第三过程、 呼叫结束时, MSC记录呼叫结束时间, MSC生成相应话单, 并将话单发给计费系统, 计费系统据此话单进行计费结算。
说明: 通过在呼叫信令中定义 H.245消息(如打开逻辑通道消息) , 用户 终端 1可利用现有的 UUS (用户到用户信令)机制传递这些 H.245消息, 也可 以通过呼叫信令通道传递 H.245消息, 这样 MSC就不用通过媒体网关控制接口 监测 H.245消息, 而是直接从呼叫信令通道获得 H.245消息, 从中判断出呼叫 类型 (如可视电话呼叫) 。
若采用在线计费方式时, 需要对 SSP与 SCP的 CAMEL (移动网增强逻辑 制定应用) 交互过程的消息进行扩展, 使系统能够获得计费信息, 从而根据 计费信息进行计费。
当有呼叫被发起时, MSC ( SSP )向 SCP触发智能业务的处理过程, 在发 往 SCP的 IDP消息中指示呼叫的业务类型, 所述的 IDP消息中的业务类型可包 括可视电话业务类型。 若 MSC已经确认该呼叫为可视电话呼叫, 则其在发往 SCP的 IDP消息中指示该呼叫是一个可视电话呼叫。 , , _ ,
SCP收到 MSC的 IDP消息后, 通过向 MSC下达带有呼叫被允许时长的 AC (计费请求) 消息, 指示 MSC, 在当前业务类型下, 呼叫被允许进行多长时 间的通话。
MSC根据 SCP下达的 AC消息对呼叫的时长进行控制, 当用户提前结束通 话, 或通话时长达到规定值, 或呼叫中途发生业务更改时, 向 SCP上报带有实 际通话时长的 ACR消息, 以便向 SCP报告呼叫从最近一次 AC消息下达以来, 以该业务类型连续通话的时长, SCP据此对呼叫进行本段呼叫的计费。对于中 途发生业务更改的情况, MSC向 SCP报告更改后的业务类型, 同时可以报告业 务更改的发起者。
通话时长达到规定值或呼叫中途发生业务更改, SCP根据其业务逻辑可以 选择终止呼叫, 或让呼叫继续进行。 若让呼叫继续进行, 则由 SCP下达新的 AC消息, 开始新一段呼叫的计费。 下面参照图 3描述上述的在线计费过程。
实施例 2—在线计费 1
如图 3所示, 本实施例的呼叫场景为: 智能用户 1向普通用户 2进行语音 呼叫, 通话过程中用户发起业务更改, 升级为可视电话呼叫。
' 步骤 31、 智能用户 1发起语音呼叫, MSC ( SSP )触发智能, 向 SCP上报 步骤 32、 SCP下发 RRBE, 以便使 MSC在某事件(比如拆线时)发生时向 SCP上报报告。
步骤 33、 SCP根据语音业务的费率确定用户的最大允许的通话时长,通过 AC消息下发给 SSP。
步骤 34、 SCP下发 CONTINUE消息使呼叫继续进行。
步骤 35、 在语音通话过程中, 用户 1发起业务更改, 将业务更改为可视电 话业务, SSP向 SCP上报业务更改消息, 指明业务更改的发起者为主叫方。
步骤 36、 SSP向 SCP上报前一段语音呼叫的 ACR消息,报告实际通话时长, SCP据此对用户按语音的费率进行扣费。
步骤 37、 SCP按照可视电话的费率重新确定允许的最大呼叫时长, 用 AC , _
消息通知 SSP, 开始新的一段可视电话呼叫的计费。
步骤 38、 SCP向 SSP下发 CONTINUE消息, 使呼叫继续进行。
步骤 39、 通话结束时, SSP上报最后一段可视电话呼叫的 ACR消息, SCP 根据其携带的实际通话时长, 按可视电话的费率对用户进行计费。 至此完成 在线计费的处理。
对于上述的在线计费方法还可进行改进, 即, SCP收到 MSC ( SSP )的 IDP 消息后, 向 MSC下发不同的业务所对应费率表, 以及呼叫可用金额。 这样, 当发生业务更改时, MSC不必上报时长信息, 可直接根据业务所对应费率表, 以及呼叫可用金额控制呼叫, 当金额不足或呼叫结束时, MSC将可用金额上 报给 SC , 以便 SCP进行计費。 下面参照图 4描述这种计费方法。
实施例 3—在线计费 2
在本实施例中, 呼叫场景为: 智能用户 1向普通用户 2进行语音呼叫, 通 话过程中用户发起业务更改, 升级为可视电话呼叫。
步骤 41、智能用户 1发起语音呼叫, MSC( SSP )触发智能,向 SCP上报 IDP。 步骤 42、 SCP下发 RRBE, 以便使 MSC在某事件(比如拆线时)发生时向
SCP上报报告。
步驟 43、 SCP通过 AC消息将用户可用额度和费率表发给 SSP。
步骤 44、 SCP下发 CONTINUE消息使呼叫继续进行。
步骤 45、 在语音通话过程中, 对业务类型进行更改, 如将业务类型更改 为可视电话业务, MSC按语音业务的费率及语音通话时长相乘得到已用额度, 从总的额度中扣除后, 得到余额。
步骤 46-步 47、 通话结束时, MSC扣除可视电话呼叫所用额度, 得到最 终余额, 将其上报给 SCP, 完成在线计费的处理。
在线计费方法还可如下实现, 即, SCP收到 MSC ( SSP ) 的 IDP消息后, 向 MSC ( SSP )下发呼叫中当前要进行的业务所对应的费率信息, 结合已有的 AOC业务对用户进行计费。 当发生业务更改时, MSC ( SSP )向 SCP报告业务 更改后所进行的业务类型, SCP向 MSC ( SSP )下发新业务所对应的费率信息, , '
指示 MSC ( SSP )按新费率进行计费。
