Description

一种策略的确定方法及装置 技术领域
本发明涉及通信技术领域，特别涉及一种策略的确定方法及装置。
背景技术
为了应对无线宽带技术的挑战，保持第三代合作伙伴计划(3rd Generation Partnership Project，简称3GPP)网络的领先优势，3GPP制定了移动通信网络的长期演进(Long Term Evolution，简称LTE)计划，在此演进计划的指导下，定义了新的移动通信网络架构，即***架构演进(System Architecture Evolution，简称SAE)网络***的架构。
图1为现有技术中SAE网络***的架构的示意图。如图1所示，当用户设备(User Equipment，简称UE)通过通用分组无线***业务支持节点(Serving General Packet Radio System Support Node，简称SGSN)接入SAE网络***时，UE可以通过S4接口接入到服务网关(Serving Gateway，简称SGW)，然后通过S5接口接入到分组数据网络网关(Packet Data Network Gateway，简称PDN-GW或PGW)，UE也可以通过Gn/Gp接口直接接入到PGW。SAE网络***中的主要网元的功能描述如下：
移动性管理实体(Mobility Management Entity，简称MME)：主要负责演进型通用移动通讯***陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network，简称E-UTRAN)中UE的移动性管理、会话管理、非接入层(Non-Access Stratum，简称NAS)信令的加密和完整性保护、为UE分配临时身份标识、PGW和SGW的选择等功能。MME对应于通用移动通讯***(Universal Mobile Telecommunications System，简称UMTS)内部SGSN的控制平面部分。
SGW：主要负责在UE和PGW之间中继用户业务流，以及在基站间切换时作为锚定点。
PGW：主要负责用户地址分配、策略控制和计费规则的执行以及合法监听相关功能。
策略和计费规则功能(Policy and Charging Rules Function，简称PCRF)实体：该功能实体根据用户接入网络的限制、运营商策略、用户签约数据以及用户当前正在进行的业务信息等决定对应的策略，并将该策略提供给传输网关执行，从而实现策略计费控制。
归属用户服务器(Home Subscriber Server，简称HSS)：负责存储用户的签约信息。
运营商IP业务(Operator’s IP Services)：运营商IP(Internet Protocol，互联网协议)业务在LTE网络中通过IP多媒体子***(IP Multimedia Subsystem，简称IMS)网络实现。此外，包交换流业务(Packet Switched Streaming Service，简称PSS)技术是3GPP定义的一种向用户提供流媒体业务的技术，PSS网络架构中主要包括移动终端和网络侧的PSS服务器。
在图1所示的SAE网络***的架构的基础上，为了探测接入网中小区的拥塞状态，3GPP引入了无线接入网拥塞感知功能(Radio Access Network Congestion Awareness Function，简称RCAF)实体。图2为引入RCAF实体的SAE网络***的架构的示意图。如图2所示，RCAF实体通过无线接入网(Radio Access Network，简称RAN)的操作、管理和维护(Operation，Administration and Maintenance，简称OAM)***与RAN相连接，获取小区的拥塞状态，通过MME或SGSN请求小区中的UE或接入点名称(Access Point Name，简称APN)的信息，然后，RCAF实体向PCRF实体通知UE所在的小区的拥塞状态。图2所示的架构中，还包括数据流探测功能(Traffic Detection Function，简称TDF)实体和策略和计费执行功能(Policy and Charging Enforcement Function，简称PCEF)实体。TDF实体主要用于检测网络流量。PCEF实体与PGW可以为合设的网络设备，PCEF实体主要用于执行PCRF实体决定的策略。

可选的，下行数据流的传输质量还包括接收下行数据流的终端向接入网设备所反馈的信道质量的信息。步骤301还包括：PCRF实体接收接入网设备发送的信道质量的信息。例如，PCRF实体可以接收接入网设备通过RCAF实体发送的信道质量的信息；或者，PCRF实体也可以接收接入网设备通过MME发送的信道质量的信息。

可选的，PCRF实体还向PCEF实体发送该服务质量策略。例如，PCRF实体可以发起修改互联网协议连通性接入网(Internet Protocol-Connectivity Access Network，简称IP-CAN)会话，以使得PCEF实体获取服务质量策略，并根据服务质量策略，调整下行数据流的传输比特率和下行数据流的传输参数中的至少一种。
下面以一示例性应用场景对本实施例的方法进行举例说明。假设运营商指 定了某种业务类型的下行数据流的传输比特率的范围，该范围包括最小比特率和最大比特率，那么，PCRF实体可以实时获得这种业务类型的下行数据流的传输比特率等传输质量。当这种业务类型的下行数据流的传输比特率低于最小比特率时，PCRF实体可以向接收这种业务类型的下行数据流的终端推送加速通知，提示可以加速。加速通知的推送方式可以是短信。当收到终端同意加速的反馈后，PCRF实体可以确定服务质量策略，服务质量策略为将下行数据流的传输比特率调整为传输比特率的目标值，该目标值可以在传输比特率的范围内。然后，PCRF实体向PCEF实体发送该服务质量策略，以使得在PCEF实体实体执行该服务质量策略后，下行数据流的传输比特率得到提高。
本实施例中，PCRF实体通过获取下行数据流的传输质量，根据下行数据流的传输质量，确定下行数据流的服务质量策略，从而调整下行数据流的传输质量。其中，获取的下行数据流的传输质量可以反映实际网络环境，这样，PCRF实体能够根据实际网络环境确定服务质量策略。例如，当下行数据流的传输比特率较低时，服务质量策略为提高该下行数据流的传输比特率，从而能够改善下行数据流的传输质量，提升用户体验。
