Description

业务处理方法、PCRF以及业务处理系统
本申请要求于2015年3月23日提交中国专利局、申请号为201510127887.5、发明名称为“业务处理方法、PCRF以及业务处理系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域，尤其涉及业务处理方法、PCRF以及业务处理系统。
背景技术
在通信网络中，网络服务提供商向用户提供业务服务时，需要考虑服务质量，以满足用户对业务质量的要求，针对该需求，第三代通信系统合作计划(3GPP，3rd Generation Partnership Project)标准定义了策略控制和计费(PCC，Policy Control and Charging)架构，该架构可以检测业务，针对不同的业务进行服务质量(Qos，Quality of Service)控制和计费控制。此外，网络服务提供商在Gi口局域网(Gi-LAN，Gi Local Area Network)上为用户提供增值业务服务，例如防火墙、网络地址转换(NAT，Network Address transform)或视频优化等。
当前3GPP定义的PCC机制下的网络资源预留流程大致如下：当用户设备(UE，User Equipment)访问应用功能实体(AF，Application Function)提供的业务时，AF向策略与计费规则功能实体(PCRF，Policy and charging Rules Function)发送Rx会话请求，请求中携带业务信息，PCRF保存业务信息，根据业务信息生成控制策略，下发控制策略到策略与计费执行功能实体(PCEF，Policy and Charging Enforcement Function)，PCEF执行网络资源预留流程。
但是，当增值业务处理器对网络服务提供商提供的某些增值业务(比如视频优化服务)的业务进行处理之后，处理后的业务所占用的网络资源发生变化，在现有的网络资源预留流程中，PCRF仍然按照AF通过Rx接口下发的业务信息制订控制策略，发送给PCEF，由PCEF根据控制策略进行网络资源预留，此时用户获取的网络资源是增值处理前的业务占用的网络资源，而不是增值处理后的业务所需要的网络资源，该预留的网络资源与实际用户需求不相关，影响用户的业务体验。

PCRF通过Rx接口与AF相连，通过Gx接口与PCEF相连，与SPR通过Sp接口相连，通过Sd接口与TDF相连，PCEF通过Gx接口与PCRF相连。
在本发明实施例中，AF是一些具有执行功能网元的总称，包括第三方业务 提供商(SP，Service Provider)，或增值业务处理器等。
增值业务处理器为对业务进行增值处理的AF，可以改变业务的业务信息，可以是视频优化器，音频优化器，防火墙或NAT等，还可以是网络服务提供商提供的其他用于增值业务的AF，此处不作限定。
请参阅图2，本发明实施例中业务处理方法的一个实施例包括：
201、PCRF获取业务的业务信息；
PCRF可以获取业务的业务信息，业务信息可以来自AF，PCEF或TDF。
业务信息为能够表示业务的参数，用于PCRF对业务进行决策，可以包括业务标识、业务类型、业务格式、业务优先级、带宽或码率等，还可以包括业务的其他信息，此处不作限定。
202、PCRF根据用户信息以及业务信息得到业务需要QoS保障的信息以及业务链信息；

当用户为QoS保障用户，且用户访问的该业务属于网络服务提供商的保障业务时，PCRF会生成针对该业务的QoS保障的信息，并生成业务链信息，业务链信息为能够表示业务链系统中业务链的信息，该业务链信息与业务链对应，业务链包括至少一个增值业务处理器。业务链信息包含增值业务类型列表和/或业务链标识，增值业务类型列表中包括至少一个增值业务类型，增值业务处理器可以对业务进行增值处理。

203、当PCRF根据业务链信息确定业务占用的网络资源会被改变时，则向增值业务处理器发送业务标识以及业务需要QoS保障的信息；
当PCRF根据业务链信息确定业务占用的网络资源会被改变时，表示该业务链中包含会改变网络资源的增值业务处理器，该业务经增值业务处理器处理后，该业务的业务信息会被改变，需要为该业务调整该业务占用的网络资源。
由于PCRF向增值业务处理器发送业务标识以及业务需要QoS保障的信息 的过程为现有技术，此处不再赘述。
增值业务处理器接收业务标识之后，根据该业务标识可以确定业务，对该业务进行增值处理得到目标业务，并获取目标业务信息，根据业务需要QoS保障的信息将目标业务信息返回。
204、PCRF接收增值业务处理器返回的业务标识对应的业务的目标业务信息；
需要说明的是，上述增值业务处理器会改变业务占用的网络资源，增值业务处理器可以直接将目标业务信息发送到PCRF，也可以通过其他网元将目标业务信息发送到PCRF，此处不作限定。
205、PCRF根据目标业务信息生成第一控制策略；
由于目标业务信息包含目标业务占用的网络资源的信息，因此PCRF接收目标业务信息之后，可以根据该目标业务信息生成第一控制策略，以预留目标业务占用的网络资源。
需要说明的是，上述业务经增值业务处理器处理后，所得目标业务信息包含的QoS参数与处理前的业务信息包含的QoS参数不同，PCRF可以根据目标业务信息中的QoS参数生成第一控制策略，QoS参数用于控制处理后的业务占用的网络资源。
第一控制策略为用于控制业务占用网络资源的PCC规则，可以包括规则名，业务流标识，QoS参数等，还可以包括业务的其他信息，此处不作限定。
QoS参数用于对业务进行控制，可以包括以下参数，
服务质量标准(QCI，Qos Class Identifier)：网络节点可以根据QCI处理数据包，不同的QCI对应不同的丢包率、时延或抖动；
资源分配保持优先级(ARP，Allocation/Retension priority)：用于指示业务流在网络资源不足时，是否可以抢占其它业务流的资源或者是否可以被其它业务流抢占；
保证比特速率(GBR，Guranteed Bit Rate)，是指在网络资源紧张的情况下，业务能够使用最小带宽；或
最大比特速率(MBR，Maximum Bit Rate)，是指业务流的最大带宽，即业务流占用的网络带宽需要小于此带宽。
206、PCRF向PCEF发送第一控制策略，使得PCEF根据所述第一控制策略预留第一网络资源。
PCRF生成第一控制策略之后，向PCEF发送第一控制策略，PCEF可以根据第一控制策略预留第一网络资源，上述第一网络资源为目标业务占用的网络资源。
PCEF根据第一控制策略预留目标业务占用的网络资源的具体过程为现有技术，此处不再赘述。
本发明实施例中，PCRF获取业务信息，根据用户信息以及业务信息进行业务链决策，得到业务需要QoS保障的信息以及业务链信息，当PCRF根据业务链信息确定业务占用的网络资源会被改变，则向增值业务处理器发送业务标识以及业务需要QoS保障的信息，PCRF接收增值业务处理器返回的业务标识对应的业务的目标业务信息，PCRF根据目标业务信息生成第一控制策略，向PCEF发送第一控制策略，使得PCEF根据第一控制策略预留网络资源，此时用户所用的网络资源为增值处理后的保障业务所对应的网络资源，满足了用户的实际需要，提高了用户的业务体验。
可选的，在图2所示实施例的基础上，本发明实施例中业务处理方法的另一个实施例中，上述业务链信息包括增值业务类型列表，则上述PCRF根据上述业务链信息确定上述业务占用的网络资源会被改变具体包括：
上述PCRF判断上述增值业务类型列表是否包含预设业务类型，若包含，则确定上述业务占用的网络资源会被改变。
本实施例中，网络服务提供商可以为用户提供的增值业务有内容过滤、NAT、防火墙、音频优化或视频优化等。网络服务提供商可以将会改变业务信息的增值业务设置为预设业务类型。业务链信息包含的增值业务类型列表可以包括一种或多种增值业务类型，此处不作限定。
当上述增值业务类型列表中包含预设业务类型时，例如“视频优化”，表明处理该业务的业务链中包含视频优化器，由于视频优化器会改变视频流占用的网络资源，因此可以确认业务占用的网络资源会被改变，需要为优化后的视频流预留相应的网络资源；当上述增值业务类型列表中包含的增值业务类型不是预设业务类型时，例如“NAT”，表明处理该业务的业务链中包含网络地址转换处理器，网络地址转换处理器对业务的处理不会改变业务占用的网络资源，因此可以确认业务占用的网络资源不会被改变。
可选的，在图2所示实施例的基础上，本发明实施例中业务处理方法的另一个实施例中，上述业务链信息包括业务链标识，则上述PCRF根据上述业务 链信息确定上述业务占用的网络资源会被改变可以通过如下方式来实现：
上述PCRF判断上述业务链标识是否为预设标识，若是，则确定上述业务占用的网络资源会被改变。
本实施例中，业务链标识与业务链一一对应，网络服务提供商可以将用于增值业务处理的业务链的业务链标识设置为预设标识，假设业务链标识为1，对应的业务链为“防火墙-音频优化-NAT”，该业务链会改变业务占用的网络资源，则该业务链标识属于预设标识；假设业务链标识为2，对应的业务链为“防火墙-NAT”，该业务链无法改变业务占用的网络资源，则该业务链标识不属于预设标识。
可选的，在图2所示实施例或可选实施例的基础上，本发明实施例中业务处理方法的另一个实施例中，上述PCRF根据用户信息以及上述业务信息得到上述业务需要QoS保障的信息可以通过如下方式来实现：
上述PCRF根据上述用户信息以及上述业务信息确定上述业务需要QoS保障时，生成QoS保障指示，其中，上述业务需要QoS保障的信息为QoS保障指示。
本实施例中，当用户为QoS保障用户，且用户访问的该业务属于网络服务提供商的保障业务时，PCRF可以生成一个QoS保障指示，以指示对该业务进行QoS保障。该QoS保障指示可以是一条PCC规则，或是一个二进制字符，此处不作限制。
可选的，在图2所示实施例或可选实施例的基础上，本发明实施例中业务处理方法的另一个实施例中，上述业务处理方法还包括：
上述PCRF根据上述用户信息以及上述业务信息生成控制参数；
则上述PCRF向增值业务处理器发送上述业务标识以及上述业务需要QoS保障的信息包括：上述PCRF向增值业务处理器发送上述业务标识、上述业务需要QoS保障的信息以及上述控制参数，使得上述增值业务处理器根据上述控制参数处理上述业务标识对应的业务得到目标业务信息。
本实施例中，PCRF可以根据用户信息以及业务信息生成控制参数，并向增值业务处理器发送业务标识、业务需要QoS保障的信息以及控制参数；
增值业务处理器接收业务标识、业务需要QoS保障的信息以及控制参数之后，根据业务标识确定业务，根据控制参数处理该业务得到目标业务信息，并根据业务需要QoS保障的信息向PCRF返回目标业务信息。
可选的，在图2所示实施例或可选实施例的基础上，本发明实施例中业务处理方法的另一个实施例中，上述业务处理方法还包括：
上述PCRF接收增值业务处理器发生故障的故障通知；
本实施例中，当业务链系统的增值业务处理器发生故障时，业务链系统的业务控制器或业务指挥器可以检测到该故障，将该故障的故障通知发送到PCRF，PCRF可以接收故障通知。
故障通知可以包括发生故障的增值业务处理器类型、发生故障的时间、故障类型或其他信息，此处不作限定。
需要说明的是，当增值业务处理器发生故障时，增值业务处理器无法再为用户提供增值业务，因此网络服务提供商无需为用户预留目标业务占用的网络资源，PCRF需要修改第一控制策略使得PCEF预留未增值业务占用的网络资源。
上述PCRF根据上述故障通知以及上述业务信息确定上述第一控制策略；
当发生故障的增值业务处理器为会改变业务信息的增值业务处理器时，PCRF根据故障通知以及业务信息确定第一控制策略；
当发生故障的增值业务处理器为不会改变业务信息的增值业务处理器时，PCRF可以生成告警通告，还可以执行其他流程，此处不作限定。
需要说明的是，PCRF获取业务信息之后，可以将该业务信息保存在PCRF或其他存储网元，当PCRF需要该业务信息时，PCRF可以从自身获取或其他存储网元中获取。
上述PCRF根据上述业务信息对上述第一控制策略进行修改得到第二控制策略；
第一控制参数中的Qos参数用于控制增值处理器处理后的业务所占的网络资源，第二控制策略中的Qos参数用于控制增值处理器处理前的业务所占的网络资源。
PCRF可以根据业务信息生成Qos参数，根据Qos参数对第一控制策略进行修改得到第二控制策略，该第二控制策略为PCRF根据用户信息以及未经增值处理的业务的业务信息进行决策所得，用于预留未增值业务占用的网络资源。
上述PCRF将上述第二控制策略发送到PCEF，使得上述PCEF根据上述第二控制策略将上述第一网络资源修改为第二网络资源。
第二网络资源为未增值业务占用的网络资源，由于增值业务处理器无法再为用户提供增值业务，此时用户访问的业务为未增值业务，网络服务提供商将 该业务对应的第一网络资源修改为第二网络资源，可以满足用户实际需求，提升用户体验。
可选的，在图2所示实施例或可选实施例的基础上，本发明实施例中业务处理方法的另一个实施例中，上述PCRF根据上述故障通知以及上述业务信息确定上述第一控制策略包括：
上述PCRF根据上述故障通知中携带的上述增值业务处理器对应的增值业务类型确定上述增值业务类型对应的业务链信息；

上述PCRF根据上述业务链信息确定上述业务链信息相应的目标业务标识；
本实施例中，目标业务为经增值处理的业务，目标业务标识与目标业务对应，具体为目标业务的IP五元组，或其他可以确定目标业务的标识，此处不作限定。
当上述目标业务标识与上述业务信息中包括的上述业务标识相同时，则上述PCRF确定上述目标业务标识对应的策略为上述第一控制策略。
可以理解的是，PCRF根据故障通知以及业务信息还可以通过其他方法确定第一控制策略，此处不作限定。
为便于理解，下面以一具体应用场景对本发明实施例中业务处理方法进行详细说明：
在本实施例的具体应用场景中，AF为视频提供商，业务为上述视频提供商提供的视频服务，业务信息为视频流信息，网络资源为带宽；并假定张三为网络服务提供商的金牌用户，且网络服务提供商为金牌用户提供视频保障服务和视频优化服务，网络服务提供商为视频提供商提供保障服务。实现本实施例的网络架构可以参考附图1所示，其中，SP位于视频提供商一侧，SPR，PCRF，PCEF，TDF，RCAF及增值业务处理器位于网络服务提供商一侧，具体实现流程如下：
PCRF可以从视频提供商获取视频的视频流信息，视频流信息包括的视频标识以“nba020703”为例；
当张三访问视频提供商提供的视频时，PCRF可以根据“张三为网络服务提供商的金牌用户”、“网络服务提供商为金牌用户提供视频保障服务和视频优化服务”以及“网络服务提供商为视频提供商提供保障服务”确定上述视频需要QoS保障，以及业务链信息，此业务链信息以“003，视频优化-NAT”为例，其 中“003”为业务链标识，“视频优化-NAT”为增值业务类型列表，包括两种增值业务类型“视频优化”和“NAT”；
假定“003，视频优化-NAT”为会改变带宽的业务链信息，则“003”为预设标识，PCRF根据“003”为预设业务标识，可以确定上述视频占用的带宽会被改变；或者，由于“视频优化”会改变带宽，也可以假定“视频优化”为预设业务类型，PCRF检测到业务链信息“003，视频优化-NAT”中“视频优化-NAT”包含“视频优化”，也可以确定上述视频占用的带宽会被改变。
业务需要QoS保障的信息可以为QoS保障指示，用于指示对该视频进行QoS保障，以“zs03”为例，PCRF向视频优化器发送“nba020703”以及“zs03”；
视频优化器对“nba020703”标识的视频进行优化可以得到目标业务信息，该目标业务信息为优化后的视频流信息，视频优化前后的视频流部分信息具体如下表所示：

PCRF接收视频优化器返回的优化后的视频流信息，例如，(‘nba020703’，‘H.263’，‘64kbps’，‘15pfs’，‘74kbps’)；
PCRF根据(‘nba020703’，‘H.263’，‘64kbps’，‘15pfs’，‘74kbps’)确定该视频对应的QoS参数，从而生成第一控制策略，第一控制策略以(‘GZ004’，‘nba020703’，‘74kbps’，‘8’，‘2’，‘30kbps’，‘500kbps’)为例，其中，‘GZ004’为PCC规则名，‘nba020703’为视频流标识，‘74kbps’为优化后视频流所需带宽，‘8’为QCI，‘2’为ARP，‘30kbps’为GBR，‘500kbps’为MBR；
PCRF向PCEF发送(‘GZ004’，‘nba020703’，‘74kbps’，‘8’，‘2’，‘30kbps’，‘500kbps’)，PCEF根据(‘GZ004’，‘nba020703’，‘74kbps’，‘8’，‘2’，‘30kbps’，‘500kbps’)将“nba020703”的视频流对应的带宽设置为74kbps，此时网络服务提供商为张三提供的带宽为视频优化后的视频流所需带宽，满足了用户的实际需求。
可以理解的是，以上举例仅为示意性的，具体实际应用中，上述视频流信 息、视频标识、业务链信息、第一控制策略还可以以其他形式表示，此处不作限定。
在实际应用中，网络服务提供商还可以设置专用于处理QoS业务的增值业务处理器，与之相应的是，网络服务提供商设置的PCRF对业务信息的处理也会不同，请参阅图3，本发明实施例中业务处理方法的另一个实施例包括：
301、PCRF获取业务的业务信息，业务信息包括业务标识；
步骤301与图2所示实施例中步骤201相似，此处不作限定。
302、当PCRF根据用户信息以及业务信息确定业务需要业务质量QoS保障时，生成业务链信息；
PCRF可以从PCC架构中其他功能实体获取的与用户有关的信息，用户信息可以是来自SPR的用户签约信息，或是来自RCAF的用户所在网络的网络拥塞信息，或是来自PCEF的用户位置信息，或是来自PCEF的接入网络类型，还可以是访问业务的用户的其他信息，此处不作限定。
当PCRF根据用户信息以及业务信息确定业务需要业务质量QoS保障时，生成业务链信息；上述业务链信息与业务链对应，业务链包含的增值业务处理器专用于处理需要QoS保障的业务，不处理非QoS保障业务。
303、PCRF向业务链系统发送业务链信息以及业务标识；
PCRF生成业务链信息之后，向业务链系统发送业务链信息以及业务标识；
业务链系统根据业务链信息确定业务链，根据业务标识确定业务，该业务链的增值业务处理器对业务进行增值处理得到目标业务信息。
304、PCRF接收业务链系统返回的业务标识对应的业务的目标业务信息；
305、PCRF根据目标业务信息生成第一控制策略；
