Description

上行业务数据流的传输装置和方法
技术领域
本发明涉及通信领域, 并且更具体地, 涉及一种上行业务数据流 的传输装置和方法。
背景技术
基于演进网络的发展需求,第三代移动通信标准化伙伴项目( 3rd Generation Partnership Project , 简称" 3GPP" )定义了策略与计费控制
( Policy and Charging Control, 简称" PCC" ) 架构。 基于 PCC架构, 演进网络能够针对检测到的不同业务数据流制定相应的服务质量
( Quality of Service, 简称" QoS" ) , 以便于保证用户业务的 QoS。
一般地, 在 PCC架构中, 策略和计费功能单元 (Policy and Charging Rules Function, 简称" PCRF" )主要根据运营商策略、 对用 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业务数据 流的业务信息等因素, 制定对应的数据流策略, 该策略称为 PCC规则
( Policy and Charging control rule )。策略及计费执行功能 ( Policy and Charging Enforcement Function, 简称" PCEF" ) 则主要用于执行 PCC 规则, 以保证用户业务的 QoS。
具体来说, 为了保证用户业务的 QoS, PCEF可以将 QoS相同的业 务数据流绑定在同一承载上,以保证业务数据流能够享受与该业务数 据流的 QoS相对应的服务质量,该 QoS主要包括 QoS类标识( QoS Class Identifier,简称 " QCI,, )或分配与抢占优先级 ( Allocation and Retention Priority , 简称 " ARP" ) 。 PCRF向 PCEF发送 PCC规则时, 该规则中除了 QoS外, 还包含有 业务数据流的描述符信息。该描述符信息可以包括五元组信息,比如, 源 IP地址、 目标 IP地址、 源端口号、 目标端口号、 协议号。 在 PCEF 完成承载绑定后,针对每个承载建立相应的业务数据流模板, 该业务 数据流模板中包含该承载所对应的所有业务数据流的描述符信息。这 样, 在收到业务数据流时, PCEF可以根据该业务数据流的描述符信 息与数据流模板进行匹配,从而找到相应的承载, 并在该承载上发送 该业务数据流。 该业务数据流可以是上行业务数据流, 也可以是下行 业务数据流。 其中, PCEF将上行业务数据流模板发送给用户设备 ( User Equipment, 简称 "UE" ) , UE按照该模板确定上行业务数 据流的承载。
目前的实现方案对于上行业务数据流来说,虽然能够实现上行业 务数据流与承载的绑定,但是该实现方案中, UE必须根据数据流模板 中标识该上行业务数据流的五元组信息,才能确定上行业务数据流所 对应的承载, 但是若用于标识上行业务数据流的不是五元组信息 时 ,UE如何确定上行业务数据流所对应的承载,这是当前亟需解决的 技术问题。

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 术人员在没有做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 ί求移动通讯 ( Global System of Mobile communication, 简称 "GSM" )系统、码分多址( Code Division Multiple Access,简称" CDMA" ) 系统、 宽带码分多址( Wideband Code Division Multiple Access, 简称 "WCDMA" )系统、通用分组无线业务( General Packet Radio Service, 简称" GPRS" )、长期演进( Long Term Evolution, 简称" LTE" )系统、 LTE频分双工 ( Frequency Division Duplex, 简称" FDD" ) 系统、 LTE 时分双工(Time Division Duplex, 简称" TDD" ) 、 通用移动通信系统 ( Universal Mobile Telecommunication System, 简称" UMTS" )、全球 互联微波接入 ( Worldwide Interoperability for Microwave Access, 简 称" WiMAX" )通信系统等。
图 1示出了本发明实施例基于的网络架构示意图。 应理解, 本发 明实施例还可以基于其它的网络架构, 本发明实施例对此不作限定。 如图 1所示,在由 UE、移动管理网元(Mobility Management Entity, 简称为 "MME" )、 服务网关 ( Serving Gateway, 简称为 "SGW" )、 分 组数据网关( Packet Data Network Gateway, 简称为 "PGW" )、 策略及 计费执行功能单元 ( Policy and Charging Enforcement Fucntion, 简称 为 "PCEF" ), 策略及计费规则功能单元( Policy and Charging Rules Function, 简称为 "PCRF,)、 接入网发现和选择功能单元(Access Network Discovery Support Functions, 简称为 "ANDSF" )组成的网络 架构中, PCRF主要用于制定 PCC规则, 所述 PCC规则中包含有业 务数据流的五元组信息以及业务数据包流的服务质量, PCEF主要用 于执行 PCRF制定的策略, 对业务数据流进行检测, 保证业务数据流 的服务质量, 并执行业务数据流与承载的绑定, 将相同 QCI/ARP的 业务数据流绑定到相同的承载上。 通常情况下, PCEF与网关设备, 例如 PGW合设。现有技术中, PCEF将业务数据流执行绑定完成后, 为承载生成上下行业务数据流的数据流模板 ( Traffic Flow Template, 简称 "TFT" ),每个承载的 TFT包含了在该承载上运行的业务数据流 的描述符信息, 比如五元组信息。 PCEF发送 TFT至 UE。 UE在发送 上行业务数据流时, 按照 PCEF所发送的 TFT, 将该上行业务数据流 的信息与该 TFT所包含的描述符信息进行匹配, 从而使用该 TFT所 对应的承载对该上行业务数据流进行传输。
但是在 PCC规则中业务数据流的描述符由应用标识取代五元组 的情况下, TFT中的业务数据流的描述符则不能是五元组信息, 而是 应用标识, 该应用标识具体用于标识业务数据流的应用类型。通常情 况下, PCEF与网关设备, 例如 PGW合设, 当前网关设备可以集成流 检测功能(Traffic Detection Function, 简称为 "TDF" ) 。 具体过程 包括:
(1)对于下行业务数据流: 当 PCEF收到下行业务数据流时, 先检 测到下行业务数据流的应用标识,根据应用标识确定相应的 PCC规则, 然后从所述规则中获取到相应的 QCI/ARP, 然后 PCEF将相同 QCI/ARP的业务数据流绑定到同一个承载上, 绑定完成后, 业务数据 流与承载的绑定关系就确定了, 每个承载的 TFT也就确定了,该 TFT中 包含在该承载上运行的业务数据流的应用标识信息。 那么当 PCEF收 到下行数据流时,可以根据该下行业务数据流的应用标识确定该下行 业务数据流所在的承载, 然后, 将该下行业务数据流运行在该承载上 传输。
(2)对于上行业务数据流: 当应用标识取代五元组信息作为业务 数据流 TFT的数据流描述符之后, UE只能根据业务数据流的应用标识 将业务数据流绑定在承载上, 但是当 UE不能识别业务数据流的应用 标识时, UE不能将上行业务数据流绑定在特定的承载上。
为此, 本发明实施方式部分提供了以下实施例, 以使得在用于标 识上行业务数据流的不是五元组信息时, 例如 TFT中包含应用标识, 该应用标识用于标识上行业务数据流时, UE仍然可以确定上行业务 数据流所对应的承载, 并进行上行业务数据流的传输。
实施例 1
1、 PCEF将指示信息通知给 UE。
该指示信息可以是反射指示 ( reflective indication ) 信息, 该 reflective indication用于通知 UE, 将该上行业务数据流绑定在相应的 下行业务数据流所在的承载上。
需要说明的是, reflective indication只是一个名称, 该 reflective indication用于指示 UE在发送上行业务数据流时, 将该上行业务数据 流绑定在相应的下行业务数据流所在的承载上。 实际使用时, 可以是 其它的名称。
具体可以是, PCEF在收到 PCRF的 IP连通性接入网 ( IP-connectivity access network,简称 "IP-CAN" )会话爹改请求消息 后, PCEF执行完成业务数据流与承载的绑定, 决定某些应用的业务 数据流运行在专有承载中, 然后向 SGW发送包含该 reflective indication的创建承载请求消息; SGW则向 MME发送包含该 reflective indication的创建承载请求消息; 然后 MME向该 UE发送包含该 reflective indication的会话管理请求消息。本发明实施例并不限定具体 釆用什么方式发送该 reflective indication 比如, 可以在上述消息中的 十办议酉己置可选 ( protocal configuration optional , 简称 "PCO" )信元 中包括该 reflective indication
另外, 该步骤具体还可以是, 在承载建立的过程中, 在针对上行 方向所建立的上行业务数据流的 TFT中包括该 reflective indication
2、 该 UE获取该 reflective indication。
具体可以是, 该 UE接收该 MME发送的会话管理请求消息, 并从 该消息中获取该 reflective indication。
如果 PCEF是通过上行业务数据流的 TFT将该 reflective indication 通知给 UE, 则 UE可以直接从该上行业务数据流模板获取该 reflective indication
3、 如果收到 reflective indication, 该 UE确定待发送的上行业务数 据流所对应的下行业务数据流,并确定该下行业务数据流对应的承载。
具体可以是,该 UE根据所述待发送的上行业务数据流的 IP地址或 端口号信息等描述符信息,确定与所述上行业务数据流的描述符信息 相同的下行业务数据流信息,从而确定出与所述上行业务数据流对应 的所述下行业务数据流, 再根据下行业务数据流的 IP地址 /端口号等 描述符信息, 以及该描述符信息与承载的对应关系, 确定下行业务数 据流对应的承载。 比如, 可以根据该下行业务数据流的描述符信息查 找每个承载所对应的业务数据流模板,如果在某个业务数据流模板中 查找到该描述符信息,则该业务数据流模板所对应的承载即为该下行 业务数据流对应的承载。
4、 该 UE使用步骤 3所确定的承载进行该上行业务数据流的传输。 对于上述实施例来说, 当 TFT中包含应用标识, 用于标识上行业 务数据流时, UE不需要知道应用标识, 不需要根据应用标识去确定 上行业务数据流的承载而是直接使用下行业务数据流的承载来作为 该下行业务数据流所对应的上行业务数据流的承载,显然这种实现方 式更方便 UE侧处理。
实施例 2
在目前的通信系统中, 有两种承载控制方式, 一种由网络侧设备 控制, 另一种由 UE侧控制。
对于网络侧设备控制的方式来说, 网络侧设备在建立承载时, 由 于网络侧设备中的网关设备集成了 TDF功能,可知道业务数据流的应 用类型, 从而可以针对业务类型指定相应的承载。
而对于 UE侧控制的方式来说, 这种方式下, 运营商则通常无法 进行控制, 比如 QQ业务。 对于这种方式来说, 开始是由 UE决定业务 数据流所在的承载, 那么只能是在网络资源建立成功, 业务数据流到 达网关设备后, 由网关设备探测到业务数据流的应用类型, 然后确定 该应用类型的业务数据流绑定的承载,如果要使用网络资源建立时所 使用承载之外的其他承载, 则需要重新发起承载修改过程, 使得 UE 能够知道该 UE当前的业务数据流应该使用哪个承载。 显然, 这种处 理方式容易增加信令的交互。
具体来说,
1、 UE向网络侧设备发送资源承载申请请求消息, 该请求消息中 携带业务数据流的应用标识( application id ) 。
该应用标识具体用于标识业务数据流的应用类型。该消息中还可 以包括业务数据流的 QCI。
该 UE可以是通过接入网发现和选择功能单元 (Access Network Discovery Support Functions,简称 "ANDSF" )获取该应用的业务数据 流的检测规则, 根据该检测规则, 获取业务数据流的应用标识, 此时 UE可以进行深度报文解析 (Deep Packet Inspection,简称 "DPI" ), 检 测获取业务数据流的应用标识。
2、 网络侧设备接收该资源承载申请请求消息, 并获取该请求消 息中的应用标识。
具体来说, 可以是 MME接收 UE发起的承载资源申请请求消息, 并向 SGW发送承载资源命令消息; SGW则向 PCEF发送承载资源命令 消息; PCEF则向 PCRF发送 IP-CAN会话修改指示。
如果上述步骤 1中发送的资源承载申请请求消息中包括该业务数 据流的应用标识与 QCI, 则网络侧传输的上述各个消息中同样可以包 括该应用标识与 QCI。 3、 网络侧 居该应用标识, 为该业务数据流分配相应的 QoS, 并根据该 QoS将业务数据流绑定到相应的承载上。
具体来说, 可以由网络侧的 PCRF根据该应用标识, 为该业务数 据流分配相应的 QoS, 并通过 IP-CAN会话确认消息, 将所分配的 QoS 发送给 PCEF; PCEF则根据该 QoS将业务数据流绑定到相应的承载上。
其中, PCEF具体可以是将具有相同 Qos ( QCI/ARP )的业务数据 流绑定到同一个承载上。
4、 PCEF向 SGW发起创建 /更新承载请求;
5、 SGW向 MME发送创建 /更新 ^载请求;
6、 MME向 UE发送会话管理请求消息。
所述 4-6的步骤用于建立承载。
UE在该承载中发送当前应用标识所标识的上行业务数据流。 上述实施例中, UE直接将业务数据流的应用标识发送给网络侧 设备, 网络侧设备可以直接根据该应用标识分配相应的 QoS, 并基于 所分配的 QoS进行承载与业务数据流的绑定, 这样, 在进行承载与业 务数据流的绑定时, 已经考虑了业务数据流的应用类型, 从而使得网 络侧能够快速地根据应用类型进行业务数据流与承载的绑定,而不会 增加信令开销。 UE可以在确定的承载上传输上行业务数据流, 以实 现该上行业务数据流与承载的绑定。
实施例 3
1、 UE通过 ANDSF获取业务数据流的应用标识与相应的 QCI的映 射关系。 具体来说, ANDSF将业务数据流与 QCI的映射关系发送给 UE, 映射关系可以是运营商在 ANDS F中预配置的, 或者通过 PCRF将映射 关系发送到 ANDSF。
该应用标识具体可以是一个标识, 即对应一个业务数据流, 也可 以是一个列表, 即对应多个业务数据流。
2、 UE在发送上行业务数据流前, 确定该上行业务数据流所对应 的应用标识。
具体可以是 UE检测获取上行业务数据流的应用标识。
3、 UE根据业务数据流的应用标识与 QCI的映射关系以及所确定 的应用标识, 确定该上行业务数据流所对应的 QCI, 根据所述 QCI与 承载的对应关系确定所述 QCI对应的承载, 具备该 QCI的承载即可为 发送上行业务数据流的承载。
具体地, 每个承载对应特定的 QCI, 可以根据 QCI确定相应的承 载。
4、 UE根据步骤 3所确定的承载发送该上行业务数据流。
具体来说, 如果上述步骤 3中是直接为上行业务数据流确定相应 的承载, 则该步骤 4中, UE可以直接将上行业务数据流在该承载上进 行传输。
如果步骤 3中是为下行业务数据流确定相应的承载, 则 UE在确定 该下行业务数据流所对应的上行业务数据流的承载时,可以釆用上述 实施例 1的实现方案进行处理。
上述实施例中 UE根据 ANDSF获取业务数据流的应用标识与相应 的 QCI的对应关系, 在发送上行业务数据流时, 根据上行业务数据流 的应用标识和获取的应用标识与相应的 QCI的对应关系, 将上行业务 数据绑定在所述 QCI对应的承载上。 使得在用于标识上行业务数据流 的是应用标识时 ,UE能够确定上行业务数据流所对应的承载。
下面再结合附图及具体实施例对上述三种实现方式进行具体描 述。
