为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本发明 实施方式作进一步地详细描述。
为更好地理解本发明的技术方案, 下面首先对本发明所涉及到的一些网元 和应用场景进行简要说明。
本申请中涉及到的网元包括: 分组数据网网关 (PDN Gateway, PGW ), 服务网关( Serving Gateway, SGW )、策略控制和计费规则功能实体( Policy and Charging Rules Function, PCRF )、移动性管理实体 (Mobility Management Entity, MME)。 其中:
PGW: 该网元是为连接提供服务的分组数据网(该网络可能是运营商内部 或外部的分组网络) 的网关, 负责对用户数据流进行转发和过滤等。
SGW::主要负责在 UE和 PGW之间中继用户业务流,以及基站间切换时, 作为锚定点。
PCRF: 策略控制和计费规则功能实体, 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。
MME: 移动性管理实体, 主要完成 E-UTRAN(Evolved UMTS Territorial Radio Access Network, 演进的 UMTS陆地无线接入网)接入下 UE的移动性管 理、 会话管理、 NAS层信令的加密和完整性保护、 PGW/SGW选择等功能。 当 UE处于空闲 (Idle)态时, MME可保存承载上下文信息。
本发明实施例提供的处理上行数据的方法主要涉及到 UE、 接入网和核心 网中的 PGW。在数据传输过程中,数据包可以从 UE经由接入网而传输至核心 网, 也可以从核心网经由接入网而传输至 UE。 其中, 从 UE发出的经由接入 网而传输至核心网的数据包称为上行数据包, 反之, 从核心网发出经由接入网 而传输至 UE的数据包称为下行数据包。 本发明实施例中的 "接入网" 可以为 UTRAN(UMTS Territorial Radio Access Network, UMTS陆地无线接入网)或者 E-UTRAN系统。
在相关技术中, 上行数据必须根据下行数据包处理, 而在网络中没有下行 数据包的情况下, UE便无法对上行数据包执行差异化处理。 为解决相关技术 中存在的上述技术问题, 本发明实施例旨在于核心网侧生成用于指示 UE的上 行数据包的类别的数据流归类属性, 并将此数据流归类属性通过下行控制信令 传输给 UE, 这样, UE在接收到下行控制信令之后, 即便在没有下行数据包的 情况下, 也能够获取到数据流归类属性, 从而能够照常对上行数据包进行差异 化处理, 不受有无下行数据包的影响。 下面通过各种不同的实施例进行具体描 述。
图 1是本发明的一实施例提供的处理上行数据的方法的流程图。参照图 1, 本发明实施例提供的处理上行数据的方法包括:
11、 UE接收网络侧网元发送的携带数据流归类属性和数据流标识的下行 控制信令。
具体的, 携带的可以是数据流归类属性和数据流标识的对应关系。
其中, 所述数据流归类属性用于指示 UE的上行数据包的类别。 本发明实施例 不对本步骤中的 "下行控制信令" 进行具体限定, 其可以为能够携带数据流归 类属性的任何下行控制信令。 例如, 视不同的应用情形而定, 可以为适应于该 应用情形的下行控制信令, 当然也可以为自定义的下行控制信令。 所述下行控 制信令例如可以为下行直传消息。 其中, 所述下行控制信令中携带的数据流标 识可包括但不限于五元组信息, 即源 IP地址, 源端口, 目的 IP地址, 目的端 口, 和传输层协议号。 例如, 在实际应用中, 所述数据流标识也可能是四元组。 本发明实施例中的 "数据流归类属性" 是相对于数据流而言的, 用于区分不同 的数据流类别。 即, 相同的数据流归类属性标识相同类别的数据流, 这样, 通 过识别数据流的数据流归类属性即可以确定数据流的类别。
本发明实施例不对具体如何划分数据流类别进行具体限定, 例如可以按照 数据流业务类型来划分数据流类别, 诸如将视频业务作为一种类别, 将 QQ业 务作为另一种类别等; 又例如,可以按照数据流的优先级划分数据流类别, 即, 可以将较高优先级的数据流划分为一个类别, 将较低优先级的数据流划分为另 一个类别。 其中, 数据流优先级的划分可以单独或综合考虑用户类型(比如, 金牌用户, 银牌用户和铜牌用户)、 数据流大小等因素。 当然还可以综合考虑 业务类型和数据流优先级二者来进行数据流类别划分。 总之, 本发明实施例中 数据流类别可以按照数据流优先级划分, 可以按照业务类型划分, 也可以按照 其他方式划分, 比如综合考虑数据流类别和业务类型划分等。
在接入网设备发生拥塞时, 由于接入网设备的网络资源有限, 无法满足所 有类型的业务数据的网络资源需求, 本发明实施例通过引入数据流归类属性将 数据流进行区分能够保证在接入网设备的网络资源有限的情况下一部分类别 的数据流能够得到及时有效传输,从而能够更加合理的利用接入网设备的网络 资源来满足业务需求。
12、 所述 UE根据上行数据包的数据流标识获知上行数据包的数据流归类 属性。
例如, 根据上行数据包的数据流标识 (例如五元组), 查询网络侧网元发 送的数据流归类属性和数据流标识, 获知上行数据包的数据流归类属性。
13、 所述 UE根据所述上行数据包的数据流归类属性确定所述上行数据包 的发送顺序。
其中, 所述根据所述上行数据包的数据流归类属性确定所述上行数据包的 发送顺序可包括: 所述 UE根据所述上行数据包的数据流归类属性确定上行数 据包发送优先级, 按照所述优先级发送所述上行数据包。
本发明实施例可以用于只有上行数据流,而没有下行数据流的场景。但是, 也可以用于一种普遍的上下行数据流都存在的情况。如果本发明实施例用于不 存在下行数据流而仅存在上行数据流的情况时, 可以先判断是否仅存在上行数 据流。 其中, 一种可能的方式是判断上行数据流的五元组信息是否也存在于下 行传输流模板 (Traffic Flow Template, TFT)中, 如果不存在, 则可以认为是该 数据流仅有上行数据流, 而不存在下行数据流。 在这种情况下, 可以釆用上述 本发明实施例的技术方案。
本发明实施例提供的处理上行数据的方法, 利用网络侧网元向 UE传输携 带数据流归类属性和数据流标识的下行控制信令, 这样, UE在接收到下行控 制信令之后, 即便在没有下行数据包的情况下, 也能够获知所述上行数据包的 数据流归类属性,从而能够根据数据流归类属性确定所述上行数据包的发送顺 序, 对上行数据包进行差异化处理, 不受有无下行数据包的影响。
当 UE获取到数据流归类属性之后, 在相关技术中, UE在申请上行数据 包资源的过程中, 会将待发送的数据包映射至四个逻辑信道中, 并将逻辑信道 的状态通知接入网, 等待接入网向其分配资源。 但是, 在此过程中, UE是将 不同类别的数据包随意地放置在逻辑信道中, 并没有考虑到数据包类别的差异 性, 因而, 同一类别的数据包可能存在于多个逻辑信道中, 不利于该类别数据 包的有效传输。 在本发明的另一个实施例中, 可选地, UE 可以根据数据流归 类属性细分逻辑信道, 从而可以更有效地传输某一类别的数据包。 具体地, 本 在步骤 12中所述 UE根据上行数据包的数据流标识获知上行数据包的数据流 归类属性之后, 还可包括: 所述 UE对用于发送上行数据包的逻辑信道进行重 新划分; 所述 UE将同一类别的上行数据包映射至相同的逻辑信道中。
其中, 可选地, 所述 UE对发送上行数据包的逻辑信道进行重新划分可包 括: 所述 UE将发送上行数据包的逻辑信道的数目划分为与上行数据包的类别 数目相同。 如此, 每一上行数据包类别都对应于一个逻辑信道, 更加便于对不 同类别的数据包执行差异化处理。
其中, 可选地, 所述 UE将同一类别的上行数据包映射至相同的逻辑信道 中可包括: 所述 UE将不同类别的上行数据包映射至不同的逻辑信道中。 具体 地, 在将同一类别的上行数据包映射至相同的逻辑信道的情况下, 可能会出现 一个逻辑信道中存在多种类别的上行数据包的情况, 通过将不同类别的上行数 据包映射至不同的逻辑信道, 可保证每一类别的上行数据包都唯一对应于一个 逻辑信道。
由上可见, 在本发明实施例中, 当在步骤 12所述 UE根据上行数据包的 数据流标识获知上行数据包的数据流归类属性之后, 本发明实施例提供的处理 上行数据的方法还可包括: 所述 UE根据网络侧网元发送的数据流归类属性划 分上行逻辑信道; 所述 UE将所述上行数据包映射至所述上行数据包的数据流 归类属性对应的逻辑信道中。
同时, 在申请资源的过程中, 相关技术并没有考虑到数据包的不同的数据 流归类属性,所以在申请资源过程中,不同类别的数据包不能得到差异化处理。 在本发明的另一个实施例中, 可选地, 在申请资源的过程中, UE 可以将数据 流归类属性告知网络侧,从而使得网络侧可以根据数据流归类属性执行差异化
11至步骤 13夕卜,在步骤 12中所述 UE根据上行数据包的数据流标识获知上行 数据包的数据流归类属性之后, 还可包括: 所述 UE向接入网发送申请资源消 息, 所述申请资源消息中携带上行逻辑信道对应的数据流归类属性。
接入网在接收到上述申请资源消息之后, 即可根据所述数据流归类属性进 行资源分配。 具体地, 即根据 UE发送申请资源消息中携带上行逻辑信道对应 的数据流归类属性确定为 UE分配的资源, 可以向发送高优先级数据包的 UE 优先分配资源或分配更多的资源, 而向发送低优先级数据包的 UE分配较少的 资源或不分配资源。
若 UE发送的申请资源消息中携带的数据流归类属性指示的优先级较低, 则接入网可能不会向该 UE分配资源。 若 UE发送的申请资源消息中携带的数 据流归类属性指示的优先级较高,则接入网尚有资源向该 UE分配资源。在 UE 发送的申请资源消息中携带的数据流归类属性指示的优先级较高,接入网向所 述 UE分配资源的情况下, 进一步地, 在所述 UE向网络侧网元发送申请资源 消息之后, 所述 UE可接收所述接入网根据所述上行逻辑信道对应的数据流归 类属性而分配的资源。
UE接收到网络侧分配的资源之后, 即可向网络侧传输上行数据包, 在此 之前, 所述 UE可以在所述数据流归类属性所指示的类别对应的上行数据包中 标记所述数据流归类属性, 具体地, 可以在 IP数据包头的差分服务代码点 (Differentiated Services Code Point, DSCP)字段标识所述数据流归类属性。 在标 记所述数据流归类属性之后, 所述 UE即可经由接入网向核心网网元发送携带 所述数据流归类属性的上行数据包。 图 2是本发明的一实施例提供的处理上行数据的方法的流程图。参照图 2, 本发明实施例提供的处理上行数据的方法包括:
21、 接入网接收来自 PGW的下行控制信令, 所述下行控制信令中携带数 据流的数据流归类属' \i和数据流标识。
其中, 所述数据流归类属性用于指示 UE的上行数据包的类别。
22、 所述接入网向 UE发送携带所述数据流归类属性和数据流标识的下行 控制信令, 以使得 UE确定发送上行数据包的发送顺序。
其中, 接入网向 UE发送的所述下行控制信令例如可以为下行直传消息。 本发明实施例提供的处理上行数据的方法,接入网在获取到数据流的数据 流归类属性之后, 向 UE传输携带数据流归类属性和数据流标识的下行控制信 令, 这样, UE在接收到下行控制信令之后, 即便在没有下行数据包的情况下, 也能够获知数据流归类属性, 从而能够照常对上行数据包进行差异化处理, 不 受有无下行数据包的影响。
可选地, 在本发明的另一个实施例中, 在步骤 22所述接入网向 UE发送 携带所述数据流归类属性和数据流标识的下行控制信令之后, 本发明另一实施 例提供的上行数据的处理方法除了包括步骤 21-22外, 还可包括:
所述接入网接收所述 UE发送的申请资源消息, 所述申请资源消息中携带 所述数据流归类属性;
所述接入网根据所述数据流归类属性进行资源分配。
可选地, 在本发明的另一个实施例中, 在所述接入网向 UE发送携带所述 数据流归类属性和数据流标识的下行控制信令之后, 本发明另一实施例提供的 上行数据的处理方法除了包括步骤 21-22外, 还可包括:
所述接入网接收来自 UE的携带所述数据流归类属性的上行数据包; 所述接入网向核心网网元发送携带所述数据流归类属性的上行数据包。 图 3是本发明的一实施例提供的处理上行数据的方法的流程图。参照图 3, 本发明实施例提供的处理上行数据的方法包括:
31、 PGW 获取数据流的数据流归类属性, 所述数据流归类属性用于指示 UE的上行数据包的类别。
在本发明实施例中, PGW 中可集成数据流探测功能 (Traffic detection function, TDF), 当然 PGW也可以与 TDF分设。 基于如上两种情形, PGW可 以通过不同的方式来获取数据流的数据流归类属性。
具体地, 当 PGW中集成 TDF时, 本步骤中, 所述 PGW获取数据流的数 据流归类属性可包括:所述 PGW接收来自于 PCRF的用户签约信息;所述 PGW 探测数据包的业务类型; 所述 PGW根据接收的用户签约信息和探测的数据包 的业务类型, 生成数据流归类属性。
当 PGW与 TDF分别单独设置时, 本步骤中所述 PGW获取数据流的数据 流归类属性可包括:
所述 PGW接收来自 PCRF的数据流的数据流归类属性, 其中, 所述数据 流的数据流归类属性由所述 PCRF生成; 或者,
所述 PGW接收来自 TDF的数据流的数据流归类属性, 其中, 所述数据流 的数据流归类属性由所述 TDF生成。
32、 所述 PGW向接入网发送携带所述数据流归类属性和数据流标识的下 行控制信令。
其中, 所述下行控制信令例如可以为更新承载请求消息。
本发明实施例提供的处理上行数据的方法, PGW在获取到数据流的数据 流归类属性之后, 通过接入网向 UE传输携带数据流归类属性和数据流标识的 下行控制信令, 这样, UE在接收到下行控制信令之后, 即便在没有下行数据 包的情况下, 也能够获取到数据流归类属性, 从而能够照常对上行数据包进行 差异化处理, 不受有无下行数据包的影响。
可选地, 本发明的另一实施例提供一种处理上行数据的方法, 所述方法除 了包括步骤 31-32之外,在步骤 32所述 PGW向接入网发送携带所述数据流归 类属性和数据流标识的下行控制信令之后, 还可包括:
所述 PGW接收 UE经由接入网而发送的携带所述数据流归类属性的上行 数据包;
所述 PGW检测所述上行数据包中的所述数据流归类属性是否正确; 若不正确, 则不传输所述上行数据包。
在本发明实施例中, PGW通过对来自 UE的上行数据流归类属性进行检 测, 能够有效阻止来自 UE的数据流归类属性不对的数据包。 为了更好地理解本发明的技术方案, 下面通过具体实施例进行进一步阐 述。 实施例提供的处理上行数据的方法的中心思想是在核心网侧的网元设备在为 UE分配上行 TFT时可以将各个分组过滤器(五元组信息 ) 以及其所属的数据 流归类属性通知 UE, 比如各个分组过滤器的优先级信息或者业务类型等归类 信息。 那么 UE在收到这些信息后, 可以根据这些信息将不同 SDF的数据流进 行差异化处理, 比如优先发送某些类型的数据包等。
以下过程以网络侧发起的不修改服务质量 (Quality of Service, QoS)的承载 修改过程为例描述。 具体地, 本实施例提供的方法包括:

其中, 视 PGW是否集成 TDF而定, 可以针对以下情形以不同方式获取数 据流的数据流归类属性:
