Description

用量监控方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种用量监控方法及装置。
背景技术
随着策略和计费控制(Policy and Charging Control，简称为PCC)架构不断演进，图1是根据相关技术中的PCC逻辑架构示意图，如图1所示，PCC架构包含如下几个功能实体：策略控制与计费规则功能实体(Policy and Charging Rules Function，简称为PCRF)、策略和计费执行功能实体(Policy and Control Enforcement Function，简称为PCEF)、承载绑定和事件上报功能(Bearer Binding and Event Reporting Function，简称为BBERF)、应用功能(Application Function，简称为AF)、流量监测功能实体(Traffic Detection Function，简称为TDF)、用户签约数据库(Subscription Profile Repository，简称为SPR)、离线计费系统(Offline charging system，简称为OFCS)、在线计费系统(Online charging system，简称为OCS)。
PCRF主要负责策略和计费规则的制定，通过Gx接口将制定的PCC策略和计费规则下发给PCEF，PCEF安装、执行PCC策略，并上报相关事件，与计费系统交互计费信息。PCRF通过Gxx接口将业务服务质量(Quality of Service，简称为QoS)规则下发给BBERF，BBERF不和计费系统交互计费信息，只负责承载绑定和相关事件的上报。PCRF通过Sd接口把需要监控的业务信息下发给TDF，TDF执行业务监控，并上报给PCRF。AF通过Rx接口向PCRF提供业务信息。SPR保存了用户签约的业务信息，PCRF可以通过Sp接口向SPR查询用户签约的业务信息。OCS通过Sy接口向PCRF报告与用户消费相关的策略计数器状态信息。PCEF通过Gy接口将在线计费信息发送给OCS进行在线计费的统计，通过Gz接口将离线计费信息发送给OFCS。TDF通过Gyn接口将基于业务的在线计费信息发送给OCS，通过Gz n接口将基于业务的离线计费信息发送给OFCS。
目前PCRF系统有很多场景主动查询PCEF要求上报用户用量，如0点清零，忙闲时切换等场景。在0点时系统用量清零前，PRCF主动查询PCEF要求上报用户用量，然后累计该用户当日用量，次日用量清零重新计数。在忙闲切换时，PCRF也会主动查询PCEF要求上报用户用量，对忙时、闲时用量分别统计，便于运营商对忙时、闲时执行不同的策略、计费控制。
然而，此类PCRF批量主动触发查询用量的方式，存在如下缺陷：
1、不管是0时清零触发，还是忙闲时切换触发用量查询，会增加PCRF系统和PCEF/TDF系统间瞬时消息流量，如推送重授权请求(Re-Auth-Request，简称为RAR)要求PCEF/TDF上报用量，PCEF/TDF在回重授权应答(Re-Auth-Answer，简称为RAA)后，通过信用控制更新请求(Credit-Control-Request Update，简称为CCR-U)主动上报用量；
2、不管是0时清零触发，还是忙闲时切换触发用量查询，都会有用量统计不及时，存在一定的延时，例如在0点前多长时间(有很多系统是提前5分钟推送RAR要求上报用量)去查询。
带来的后果是：
1.PCRF定时批量主动查询用量的方式，增加系统间消息负荷，可能导致PCEF/TDF系统CPU瞬时冲高；
2.PCRF定时批量主动查询用量的时机问题，不管是准时查询还是按一定提前量的方式查询，可能会存在用量提前或滞后统计情况，存在统计用量不准确，达不到PCRF精确控制的目的。
针对相关技术中的用量监控方式存在的上述问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中，提供了一种用量监控方法，图2是根据本发明实施例的一种用量监控方法的流程图，如图2所示，该方法包括如下步骤：
步骤S202，策略控制与计费规则功能实体(PCRF)向进行用量监控的功能实体发送用于监控用量信息的用量监控规则，同时携带上报所述用量监控规则对应的监控结果的上报时间；
步骤S204，所述PCRF接收所述进行用量监控的功能实体在所述上报时间上报的所述监控结果。
本实施例通过上述步骤，PCRF在向进行用量监控的功能实体发送用量监控规则的同时，还携带了监控结果的上报时间，解决了相关技术中的用量监测方式存在的增加系统间消息负荷且统计用量不准确的问题，从而不但使得PCRF下发用量监控的时间点能够分散开，避免下发用量监控规则导致的CPU瞬时冲高，而且能够根据用量监控规则灵活设置监控结果的上报时间，提升了统计精确性，此外也能分散开监控结果的上报时间，降低系统间消息负荷。
本实施例中，PCRF可以根据监控对象的不同类型设定所述上报时间。这样能够进一步提升统计精确性，以及降低系统间消息负荷。
其中，所述监控对象可以包括但不限于以下类型至少之一：用户类型、业务类型、接入网类型、邻接局类型等。
本实施例中，在PCRF向进行用量监控的功能实体发送用于监控用量信息的用量监控规则的过程中，所述PCRF还可以携带对上报开关的控制信息，所述上报开关设置为指示所述进行用量监控的功能实体是否开启按照所述上报时间上报所述监控结果的上报功能。
其中，在未携带所述上报开关的控制信息的情况下，可以默认指示所述进行用量监控的功能实体开启所述上报功能。
本实施例中，所述进行用量监控的功能实体包括以下至少之一：策略和计费执行功能实体(PCEF)，流量监测功能实体(TDF)。
对应于上述方法，在本实施例中还提供了一种用量监控装置，位于策略控制与计费规则功能实体(PCRF)中，该装置设置为实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图3是根据本发明实施例的一种用量监控装置的结构框图，如图3所示，该装置包括发送模块32和第一接收模块34，下面对各个模块进行详细说明：
发送模块32，设置为向进行用量监控的功能实体发送用于监控用量信息的用量监控规则，同时携带上报所述用量监控规则对应的监控结果的上报时间；第一接收模块34，与发送模块32相连，设置为接收所述进行用量监控的功能实体在所述上报时间上报的所述监控结果。
在本实施例中还提供了另一种用量监控方法，图4是根据本发明实施例的另一种用量监控方法的流程图，如图4所示，该方法包括如下步骤：
步骤S402，进行用量监控的功能实体接收策略控制与计费规则功能实体(PCRF)发送的用量监控规则及同时携带的上报所述用量监控规则对应的监控结果的上报时间；
步骤S404，所述进行用量监控的功能实体根据所述用量监控规则监控用量信息，并在到达所述上报时间时向所述PCRF上报所述监控结果。
本实施例通过上述步骤，PCRF在向进行用量监控的功能实体发送用量监控规则的同时，还携带了监控结果的上报时间，解决了相关技术中的用量监测方式存在的增加系统间消息负荷且统计用量不准确的问题，从而不但使得PCRF下发用量监控的时间点能够分散开，避免下发用量监控规则导致的CPU瞬时冲高，而且能够根据用量监控规则灵活设置监控结果的上报时间，提升了统计精确性，此外也能分散开监控结果的上报时间，降低系统间消息负荷。
本实施例中的所述进行用量监控的功能实体可以包括以下至少之一：策略和计费执行功能实体(PCEF)，流量监测功能实体(TDF)。
本实施例中，所述进行用量监控的功能实体还可以接收对上报开关的控制信息，所述上报开关设置为指示所述进行用量监控的功能实体是否按照所述上报时间上报开启所述监控结果的上报功能。
其中，在未接收到所述上报开关的控制信息的情况下，则可以默认开启所述上报功能。
其中，在到达所述上报时间之前，所述进行用量监控的功能实体如果接收到PCRF发送的所述上报开关的关闭控制信息，则可以停止按照所述上报时间上报所述监控结果。也即，上报开关(也可以称为定时监控开关)可以停止或开启定时用量的监控上报，但不会停止达到用量分片进行用量的正常上报。这里所说的定时用量的监控上报，即为协议中可进行的PCRF主动用量查询，通过下发规则时下发预约时间定时上报，减少主动查询用量的交互流程，从而降低了主动查询用量导致的系统负荷。
本实施例中，在到达所述上报时间之前，所述进行用量监控的功能实体如果接收到PCRF发送的所述用量监控规则对应的更新上报时间，则可以按照所述更新上报时间向所述PCRF上报所述监控结果。通过上述更新方式，使得PCRF对上报时间的控制更加灵活。
对应于上述另一种用量监控装置，在本实施例中还提供了另一种用量监控装置，位于进行用量监控的功能实体中，该装置设置为实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图5是根据本发明实施例的另一种用量监控装置的结构框图，如图5所示，该装置包括第二接收模块52和上报模块54，下面对各个模块进行详细说明：
第二接收模块52，设置为接收策略控制与计费规则功能实体(PCRF)发送的用量监控规则及同时携带的上报所述用量监控规则对应的监控结果的上报时间；上报模块54，与第二接收模块52相连，设置为根据所述用量监控规则监控用量信息，并在到达所述上报时间时向所述PCRF上报所述监控结果。
下面结合优选实施例进行说明，以下优选实施例结合了上述实施例及其优选实施方式。
在以下优选实施例中，提供了一种实现用量定时监测控制的方法及系统，涉及策略控制与计费规则功能实体(PCRF，Policy and Charging Rules Function)与策略和计费执行功能实体(PCEF，Policy and Control Enforcement Function)/流量监测功能实体(TDF，Traffic Detection Function)之间的用量监控技术，是一种PCC(Policy and Charging Control，策略和计费控制)架构中用量定时监测控制的实现方法。
考虑到PCRF定时批量主动查询用量的方式，会导致系统间负荷瞬时冲高，甚至过冲，批量查询的时机不好把握，存在时延问题。本优选实施例提供了一种实现用量定时监测控制的方法及系统，包括PCRF根据运营商的流量规划和系统规划，能够提前下发明确的上报时间指示PCEF/TDF。PCEF/TDF存储该监控信息的上报时间，一旦监测到上报时间到，即刻上报该监控用量。PCRF通过区分用户类型、业务类型等方式设定上报时间，在PCEF/TDF定时上报用量后，PCRF就可以定时分析不同用户类型、业务方式的用量信息，然后根据上报的用量信息指示新的策略。
本优选实施例在PCRF向PCEF/TDF下发用量监控规则时，根据用户类型、业务类型等方式下发定时上报用量的时间，具体地说：
1、PCRF向PCEF/TDF下发用量监控规则时，携带需要PCEF/TDF定时上报用量的时间1；
2、PCEF/TDF发现定时上报用量的时间1到，上报该监控规则的用量；
3、PCRF根据PCEF/TDF上报的用量，进行策略控制或计费策略控制，下发定时上报用量的时间2；
4、在定时上报用量时间2到之前，运营商根据用量等信息重新规划定时上报用量时间3；
5、PCRF更新策略控制或计费策略，下发定时上报用量的新时间3；
6、PCEF/TDF发现定时上报用量的时间3到，上报该监控规则的用量；
7、PCRF根据PCEF/TDF上报的用量，进行策略控制或计费策略控制，下发定时上报用量的时间4；
8、在定时上报用量时间4到之前，运营商根据用量等信息需要取消定时上报用量；
9、PCEF/TDF对该用量监控规则不再定时上报用量。
本优选实施例通过PCRF在下发监控规则时携带定时上报用量的时间，并且能够在监控期间主动调整定时上报时间，甚至停止定时上报功能。该方案使用灵活，可根据用户类型、业务类型、接入网类型、邻接局类型等参数设置定时上报参数，满足运营商的各种定时查询、分析用量的要求。
图6是根据本发明优选实施例的定时上报用量监控流程图，如图6所示，PCRF向PCEF/TDF下发用量监控规则时，携带需要PCEF/TDF定时上报用量的时间和开启定时上报开关。PCEF/TDF检测到定时上报用量时间到，上报该监控用量使用信息。PCRF根据上报的监控用量信息，向PCEF/TDF更新用量监控规则，若不需要定时上报功能，关闭定时上报开关。
图7是根据本发明优选实施例的调整用量监控定时上报时间的流程图，如图7所示，PCRF向PCEF/TDF下发用量监控规则时，携带需要PCEF/TDF定时上报用量的时间1和开启定时上报开关。由于运营商规划要求，需要修改用量的定时上报时间，PCRF向PCEF/TDF更新用量监控规则，携带新的定时上报用量的时间2。PCEF/TDF检测到定时上报用量时间2到，上报该监控用量使用信息。PCRF根据上报的监控用量信息，向PCEF/TDF更新用量监控规则，若不需要定时上报功能，关闭定时上报开关。
图8是根据本发明优选实施例的用量监控定时上报的流程图，如图8所示，PCRF向PCEF/TDF下发用量监控规则时，携带需要PCEF/TDF定时上报用量的时间和开启定时上报开关。然后，根据用量上报信息、运营商规划要求等信息修改定时上报时间和决定是否关闭定时上报开关。
下面详细介绍定时上报用量监控，其主要步骤可以参见图8：
步骤S2：PCRF根据用户类型、业务类型、接入网类型、邻接局等参数和运营企业用量分布情况，预先设置用量定时上报时间1；
步骤S4：PCEF/TDF携带用户号码、IP地址等信息，发起用户上线流程；
步骤S6：PCRF根据用户类型、业务类型等下发监控规则，在监控信息中携带监控定时上报时间1，开启定时上报开关；
步骤S8：PCEF/TDF检测到定时上报时间1周期到；
步骤S10：PCEF/TDF上报监控的用量使用信息；
步骤S12：PCRF根据用户类型、业务类型等下发监控规则，在监控信息中更新监控定时上报时间为时间2；
步骤S14：根据运营商的用量规划调整要求，PCRF结合用户类型、业务类型等信息，在RAR中更新监控定时上报时间为时间3；
步骤S16：PCEF/TDF回送RAA成功应答，更新监控规则定时时间3；
步骤S18：PCEF/TDF检测到定时上报时间3周期到；
步骤S20：PCEF/TDF上报监控的用量使用信息；
步骤S22：PCRF根据用户类型、业务类型等下发监控规则，在监控信息中更新监控定时上报时间为时间4；
步骤S24：PCEF/TDF检测到定时上报时间4周期到；
步骤S26：PCEF/TDF上报监控的用量使用信息；
步骤S28：PCRF根据用户类型、业务类型等下发监控规则，且不再需要定时上报功能，在监控信息中更新用量分片，同时关闭定时上报开关。
表1是根据本发明优选实施例的在信用控制更新响应(Credit-Control-Answer，简称为CCA)、RAR消息中的用量监控信息中扩展定时上报时间和定时上报开关信息，若只携带定时上报时间，默认定时上报开关开启。
