Description

控制数据流绑定承载的方法及设备 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及一种控制数据流绑定承载的方法及设备。
背景技术
策略与计费规则功能(Policy and Charging Rule Function，PCRF)设备根据运营商策略、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应用业务数据流的业务信息等因素，为数据流授权生成策略与计费控制(Policy and Charging Control，PCC)规则，该PCC规则通常包括数据流标识(流模板)以及其对应的QoS(Quality of Service，QoS)信息。PCRF设备生成PCC规则后，向策略与计费增强功能(Policy and Charging Enforcement Function，PCEF)设备安装该PCC规则。PCEF设备根据PCC规则中的服务质量执行数据流承载绑定，这类PCC规则称为动态规则。另外还有一类PCC规则是非动态规则(也称为预定义PCC规则)，PCRF知道授权的QOS信息以及规则的标识，PCRF可以激活这类规则。在向PCEF设备发送的激活消息中携带该规则的标识，但是PCRF不能修改该规则中的QOS信息。
通常情况下，一个承载包含一个或多个业务数据流。PCEF需要根据PCC规则对数据流执行绑定承载的操作，也即确定该业务数据流所在的承载。基本的绑定原则是将PCC规则中的QoS参数(QCI/ARP)相同的业务数据流绑定到同一个承载中。反之，不同的QoS参数对应的业务数据流不能绑定到同一个承载中。
这样，在动态PCC规则与非动态的PCC规则对应的数据流绑定到同一个承载时，如果PCRF对动态PCC规则执行修改QoS参数(QCI\ARP)的操作，修改后的QoS参数与原来的QoS参数不同。那么，动态PCC规则中的QoS参数则与非动态的PCC规则的不同。这样，原动态PCC规则与非动态PCC规则对应的两个数据流需要绑定在两个不同的承载上。这种情况下，会增加系统中的承载数。
然而有些情况下，PCRF修改动态PCC规则中的QoS参数，或者修改缺省承载的QoS参数可能是暂时的，在一段时间后，当前QoS参数可能是 会被恢复为原来的QoS参数。例如，由于地震等天然灾害导致网络拥塞时，为某些政府官员、紧急事务管理官员提供优先接入网络的服务。系统根据用户的优先级，提高特定用户承载的QoS，进而为用户提供高优先级服务。在这种情况下，由于动态PCC规则中的QoS修改而导致的系统中的承载数量增加是不必要的。在这个短暂的过程中，系统中增加了承载，增加了系统维护的成本。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(英文：Global System of Mobile communication，简称：GSM)系统、码分多址(英文：Code Division Multiple Access，简称：CDMA)系 统、宽带码分多址(英文：Wideband Code Division Multiple Access，简称：WCDMA)系统、通用分组无线业务(英文：General Packet Radio Service，简称：GPRS)、长期演进(英文：Long Term Evolution，简称：LTE)系统、LTE频分双工(英文：Frequency Division Duplex，简称：FDD)系统、LTE时分双工(英文：Time Division Duplex，简称：TDD)、通用移动通信系统(英文：Universal Mobile Telecommunication System，简称：UMTS)、全球互联微波接入(英文：Worldwide Interoperability for Microwave Access，简称：WiMAX)通信系统等。
图1是本发明一个实施例的控制数据流绑定承载的方法的示意性流程图。图1的方法可以由PCEF设备执行。
101，策略与计费增强功能PCEF设备从策略与计费规则功能PCRF设备接收指示信息和策略与计费控制PCC规则的标识。
例如，PCEF设备从PCRF设备接收重授权请求(Re-Auth-Request，RAR)消息，该RAR消息携带指示信息和PCC规则的标识。应理解，RAR消息仅是本发明实施例的一种实现方式，使用其它消息携带指示信息和PCC规则的标识，以实现本发明实施例的实施方式都应落在本发明实施例的保护范围内。
102，PCEF设备根据指示信息，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到目标承载上。
例如，将PCC规则的标识对应PCC规则中的数据流标识所表示的数据流绑定到目标承载时，PCEF设备根据指示信息进行承载绑定，而不是直接根据承载绑定的原则采用PCC规则执行承载绑定。
根据本发明实施例的方法，在修改了动态PCC规则的QoS参数时，PCRF设备向PCEF设备发送指示信息和PCC规则的标识。然后，PCEF设备根据指示信息执行PCC规则的标识所表示的PCC规则中的的数据流标识所表示的数据流的承载绑定。这样，可以避免新增承载的情况发生，进而降低了系统维护的成本。
可选地，作为一个实施例，指示信息包括目标QoS参数、业务信息或者目标承载的标识。例如，业务信息可以为优先级业务信息。
可选地，作为另一实施例，PCEF设备根据指示信息，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到目标承载上时， 先将PCC规则的标识对应的PCC规则中的QoS参数修改为指示信息中的目标QoS参数。这种情况下，PCEF设备根据修改后的PCC规则，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到目标承载上。
例如，指示信息包括目标QoS参数。PCEF设备接收到指示信息后，先将对应的PCC规则的QoS参数修改为目标QoS参数。然后，根据修改后的PCC规则，将PCC规则的标识所表示的PCC规则中的的数据流标识所表示的数据流绑定在QoS(QCI\ARP)参数相同的承载上。
可选地，作为另一实施例，在PCEF设备根据指示信息，将PCC规则的标识对应的数据流绑定到目标承载上时，PCEF设备将PCC规则的标识表示的PCC规则中的数据流的标识表示的PCC规则中的QoS参数修改为指示信息中的业务信息对应的QoS参数。然后，PCEF设备根据修改后的PCC规则，将PCC规则的标识对应的数据流绑定到目标承载上。
例如，指示信息包括业务信息。PCEF设备接收到指示信息后，先将对应的PCC规则的QoS参数修改为业务信息对应的QoS参数。然后，根据修改后的PCC规则，将PCC规则的标识所表示的PCC规则中的的数据流标识所表示的数据流绑定在QoS(QCI\ARP)参数相同的承载上。
可选地，作为另一实施例，PCEF设备根据指示信息，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到目标承载上时，PCEF设备将PCC规则的标识对应的数据流绑定到指示信息中的目标承载的标识对应的承载上。
例如，指示信息包括目标承载的标识。PCEF设备接收到指示信息后，直接将PCC规则的标识所表示的PCC规则中的数据流标识所表示的数据流绑定在目标承载上，而不修改PCC规则的QoS参数。
可选地，作为另一实施例，目标承载的标识包括缺省承载的标识。
系统中的承载有两种，缺省承载和专有承载。缺省承载是用户建立PDN连接时的第一个承载。专有承载是缺省承载之外的其它的承载。其中，缺省承载在PDN连接期间一直存在，当该缺省承载去激活后，该PDN连接则也同时被去激活。如果系统中仅有一个PDN连接，那么，该PDN连接去激活之后，该用户被分离。
这样，PCEF设备直接将PCC规则的标识对应的数据流绑定在缺省承载 上，避免了增加新的承载。
图2是本发明另一实施例的控制数据流绑定承载的方法的示意性流程图。图2的方法可以由PCRF设备执行。
201，策略与计费规则功能PCRF设备生成指示信息，指示信息包括目标QoS参数、业务信息或者目标承载的标识。
例如，在修改了动态PCC规则的QoS参数时，PCRF设备根据修改后的动态规则生成指示信息，以指示与修改前的动态PCC规则的QoS参数相同的预定义PCC规则对应的数据流的承载绑定。业务信息可以为优先级业务信息。
又如，将修改后的动态PCC规则的QoS参数作为目标QoS参数，指示PCEF设备将对应的预定义的PCC规则的QoS参数修改为目标QoS参数。或者，如果修改动态PCC规则的QoS参数的原因是优先级业务，直接将业务信息(如，优先级业务的标识或者对应的QoS参数信息)作为指示信息。或者，直接将修改后的动态PCC规则对应的承载标识作为目标承载的标识，指示PCEF设备直接将数据流绑定在目标承载上。
202，PCRF设备向策略与计费增强功能PCEF设备发送PCC规则的标识和指示信息，以便于PCEF设备根据指示信息，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到目标承载上。
例如，PCRF设备向PCEF设备发送RAR消息，该RAR消息携带指示信息和PCC规则的标识。应理解，RAR消息仅是本发明实施例的一种实现方式，使用其它消息携带指示信息和PCC规则的标识，以实现本发明实施例的实施方式都应落在本发明实施例的保护范围内。
根据本发明实施例的方法，在修改了动态PCC规则的QoS参数时，PCRF设备向PCEF设备发送指示信息和PCC规则的标识。然后，PCEF设备根据指示信息执行PCC规则的标识对应的数据流的承载绑定。这样，可以避免新增承载的情况发生，进而降低了系统维护的成本。
可选地，作为一个实施例，PCC规则的标识包括预定义PCC规则的标识。
图3是本发明另一实施例的控制数据流绑定承载的方法的示意性流程图。图3的方法可以由PCEF设备执行。
301，策略与计费增强功能PCEF设备从策略与计费规则功能PCRF设 备接收修改缺省承载的QoS参数的指示信息。
302，如果在修改缺省承载的QoS参数前，缺省承载中有预定义PCC规则对应的数据流(例如，缺省承载中有一个或多个数据流采用预定义PCC规则)，PCEF设备将预定义PCC规则对应的数据流绑定在缺省承载上。
例如，在修改缺省承载的QoS参数前，如果缺省承载中有预定义PCC规则对应的数据流，在后续绑定该预定义PCC规则对应的数据流时，仍旧绑定在缺省承载上，而不是为该数据流建立新的承载。
可选地，PCEF可以通知PCRF当前PCC规则标识表示的PCC规则中的QOS参数，和/或所述PCC规则标识表示的PCC规则中的数据流标识表示的数据流所在的承载标识信息。比如，在重授权回答消息中包含有PCC规则标识，和/或承载标识和/或QOS参数信息等。
根据本发明实施例的方法，在修改了缺省承载的QoS参数时，PCEF设备仍旧将预定义PCC规则对应的数据流绑定在缺省承载上。这样，可以避免新增承载的情况发生，进而降低了系统维护的成本。
可选地，作为一个实施例，PCEF设备将预定义PCC规则对应的数据流绑定在缺省承载上时，先判断修改后的缺省承载的QoS参数是否属于预设的特定参数范围。
当PCEF设备确定修改后的缺省承载的QoS参数属于特定的QoS参数范围时，PCEF设备将预定义PCC规则对应的数据流绑定在缺省承载上。
图4是本发明一个实施例的策略与计费增强功能设备的示意性框图。PCEF设备40包括接收单元401和处理单元402。
接收单元401，用于从策略与计费规则功能PCRF设备接收指示信息和策略与计费控制PCC规则的标识。
例如，PCEF设备从PCRF设备接收RAR消息，该RAR消息携带指示信息和PCC规则的标识。应理解，RAR消息仅是本发明实施例的一种实现方式，使用其它消息携带指示信息和PCC规则的标识，以实现本发明实施例的实施方式都应落在本发明实施例的保护范围内。
处理单元402，用于根据指示信息，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到目标承载上。
例如，将PCC规则的标识对应PCC规则中的的数据流标识所表示的数据流绑定到目标承载时，PCEF设备根据指示信息进行承载绑定，而不是直 接根据承载绑定的原则采用PCC规则执行承载绑定。
根据本发明实施例的方法，在修改了动态PCC规则的QoS参数时，PCRF设备向PCEF设备发送指示信息和PCC规则的标识。然后，PCEF设备根据指示信息执行PCC规则的标识对应的数据流的承载绑定。这样，可以避免新增承载的情况发生，进而降低了系统维护的成本。
可选地，作为一个实施例，指示信息包括目标QoS参数、业务信息或者目标承载的标识。例如，业务信息可以为优先级业务信息。
可选地，作为另一实施例，处理单元402具体用于，将PCC规则的标识对应的PCC规则中的QoS参数修改为指示信息中的目标QoS参数；根据修改后的PCC规则，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到目标承载上。
例如，指示信息包括目标QoS参数。PCEF设备接收到指示信息后，先将对应的PCC规则的QoS参数修改为目标QoS参数。然后，根据修改后的PCC规则，将PCC规则的标识所表示的PCC规则中的的数据流标识所表示的数据流绑定在QoS(QCI\ARP)参数相同的承载上。
可选地，作为另一实施例，处理单元402具体用于，将PCC规则的标识对应的PCC规则中的QoS参数修改为指示信息中的业务信息对应的QoS参数；根据修改后的PCC规则，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到目标承载上。
例如，指示信息包括业务信息。PCEF设备接收到指示信息后，先将对应的PCC规则的QoS参数修改为业务信息对应的QoS参数。然后，根据修改后的PCC规则，将PCC规则的标识所表示的PCC规则中的的数据流标识所表示的数据流绑定在QoS(QCI\ARP)参数相同的承载上。
可选地，作为另一实施例，处理单元402具体用于，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到指示信息中的目标承载的标识对应的承载上。
例如，指示信息包括目标承载的标识。PCEF设备接收到指示信息后，直接将PCC规则的标识所表示的PCC规则中的数据流标识所表示的数据流绑定在目标承载上，而不修改PCC规则的QoS参数。
可选地，作为另一实施例，目标承载的标识包括缺省承载的标识。
系统中的承载有两种，缺省承载和专有承载。缺省承载是用户建立PDN 连接时的第一个承载。专有承载是缺省承载之外的其它的承载。其中，缺省承载在PDN连接期间一直存在，当该缺省承载去激活后，该PDN连接则也同时被去激活。如果系统中仅有一个PDN连接，那么，该PDN连接去激活之后，该用户被分离。
这样，PCEF设备直接将PCC规则的标识对应的数据流绑定在缺省承载上，避免了增加新的承载。
图5是本发明一个实施例的策略与计费规则功能设备的示意性框图。PCRF设备50包括生成单元501和发送单元502。
生成单元501，用于生成指示信息，指示信息包括目标QoS参数、业务信息或者目标承载的标识。
例如，在修改了动态PCC规则的QoS参数时，PCRF设备根据修改后的动态规则生成指示信息，以指示与修改前的动态PCC规则的QoS参数相同的预定义PCC规则对应的数据流的承载绑定。
又如，将修改后的动态PCC规则的QoS参数作为目标QoS参数，指示PCEF设备将对应的预定义的PCC规则的QoS参数修改为目标QoS参数。或者，如果修改动态PCC规则的QoS参数的原因是优先级业务，直接将业务信息(如，优先级业务的标识或者对应的QoS参数信息)作为指示信息。或者，直接将修改后的动态PCC规则对应的承载标识作为目标承载的标识，指示PCEF设备直接将数据流绑定在目标承载上。
发送单元502，用于向策略与计费增强功能PCEF设备发送PCC规则的标识和指示信息，以便于PCEF设备根据指示信息，将PCC规则的标识表示的PCC规则中的数据流的标识表示的数据流绑定到目标承载上。
例如，PCRF设备向PCEF设备发送RAR消息，该RAR消息携带指示信息和PCC规则的标识。应理解，RAR消息仅是本发明实施例的一种实现方式，使用其它消息携带指示信息和PCC规则的标识，以实现本发明实施例的实施方式都应落在本发明实施例的保护范围内。
根据本发明实施例的方法，在修改了动态PCC规则的QoS参数时，PCRF设备向PCEF设备发送指示信息和PCC规则的标识。然后，PCEF设备根据指示信息执行PCC规则的标识对应的数据流的承载绑定。这样，可以避免新增承载的情况发生，进而降低了系统维护的成本。
可选地，作为一个实施例，PCC规则的标识包括预定义PCC规则的标 识。
图6是本发明另一实施例的策略与计费增强功能设备的示意性框图。PCEF设备60包括接收单元601和处理单元602。
接收单元601，用于从策略与计费规则功能PCRF设备接收修改缺省承载的QoS参数的指示信息。
处理单元602，如果在修改缺省承载的QoS参数前，缺省承载中有预定义PCC规则对应的数据流(例如，缺省承载中有一个或多个数据流采用预定义PCC规则)，用于将预定义PCC规则对应的数据流绑定在缺省承载上。
例如，在修改缺省承载的QoS参数前，如果缺省承载中有预定义PCC规则对应的数据流，在后续绑定该预定义PCC规则对应的数据流时，处理单元602仍旧绑定在缺省承载上，而不是为该数据流建立新的承载。
可选地，PCEF可以通知PCRF当前PCC规则标识表示的PCC规则中的QOS参数，和/或所述PCC规则标识表示的PCC规则中的数据流标识表示的数据流所在的承载标识信息。比如，在重授权回答消息中包含有PCC规则标识，和/或承载标识和/或QOS参数信息等。
根据本发明实施例的方法，在暂时修改了缺省承载的QoS参数时，处理单元602仍旧将预定义PCC规则对应的数据流绑定在缺省承载上。这样，可以避免新增承载的情况发生，进而降低了系统维护的成本。
可选地，作为一个实施例，处理单元602具体用于，当PCEF设备确定修改后的缺省承载的QoS参数属于特定的QoS参数范围时，处理单元602将预定义PCC规则对应的数据流绑定在缺省承载上。
例如，PCEF设备将预定义PCC规则对应的数据流绑定在缺省承载上时，先判断修改后的缺省承载的QoS参数是否属于预设的特定参数范围。当PCEF设备确定修改后的缺省承载的QoS参数属于特定的QoS参数范围时，处理单元602将预定义PCC规则对应的数据流绑定在缺省承载上。
