本发明实施例适用于 2G网络,例如全球移动通讯系统( Global System of Mobile communication, 简称 GSM ) 网络、 3G网络, 例如通用移动通信系统 ( Universal Mobile Telecommunications System, 简称 UMTS ) 网络、 长期演 进(LTE ) 网络以及更高级的网络中上行数据报文的控制。
图 1为本发明实施例提供的一种拥塞上行控制方法流程图。 本实施例主 要说明基站如何对上行数据报文进行拥塞控制。 如图 1所示, 本实施例提供 的方法包括:
步骤 11 : 基站接收用户设备的上行数据报文。
步骤 12: 基站根据与所述上行数据报文中的流描述信息对应的拥塞上行 控制策略, 对所述上行数据报文进行拥塞控制。
基站保存有不同流描述信息对应的拥塞上行控制策略。 其中, 基站保存 的拥塞上行控制策略根据以下信息的一种或多种组合设定: 上行数据报文的 业务类型、 用户设备的用户签约信息、 用户设备接入信息和用户设备接入技 术类型。 其中, 流描述信息可以是 IP五元组信息全部或者部分, 即 IP报文 的源地址、 目的地址, 源端口号, 目的端口号和协议类型。
基站接收到上行数据报文后, 如果确定基站发生拥塞, 例如, 空口资源 不足、 基站转发能力不足, 或者上行至核心网的带宽受限等, 则查找与上行 数据报文中的流描述信息对应的拥塞上行控制策略。 如果查找到与该流描述 信息对应的拥塞上行控制策略, 则根据查找到拥塞上行控制策略对上行数据 报文进行拥塞控制。 例如, 拥塞上行控制策略可以是限制数据流带宽, 降低 数据传输优先级或者直接丟弃等。
核心网设备,例如, PGW或 GGSN,可以为基站下发拥塞上行控制策略。 核心网设备接收到用户设备的上行数据报文后, 如果确定发送上行数据报文 的终端所归属的基站经常发生拥塞, 或者, 根据 PCRF配置的信息确定需要 为基站下发与该上行数据报文中流描述信息所对应的拥塞上行控制策略, 则 向基站下发上行数据报文中流描述信息对应的拥塞上行控制策略, 使基站保 存拥塞上行控制策略。 例如, 基站接收核心网设备发送的下行数据报文, 所 述下行数据报文包括与所述下行数据报文中的流描述信息对应的拥塞上行控 制策略, 所述拥塞上行控制策略用于对与所述下行数据报文具有相同流描述 信息的上行数据报文进行拥塞控制。 基站接收核心网设备发送的下行数据报 文后, 保存其中的流描述信息和对应的拥塞上行控制策略。 基站可以建立拥 塞上行控制策略库, 用于保存不同流描述信息对应的拥塞上行控制策略。
下面举例说明核心网络为基站下发拥塞上行控制策略的过程:
1. 用户设备 ( User Equipment, 简称 UE )需要上传 Video文件给特定网 站时, 向基站 A发送上行数据报文, 该上行数据报文的流描述信息为: 源地 址 UE IP、 目的地址特定 IP。
2. 核心网设备接收到该上行数据报文后,根据 UE的位置信息判断出 UE 所归属的基站 A经常发生拥塞时,确定需要为基站 A下发拥塞上行控制策略。 核心网设备设置的与流描述信息: 源地址 UE IP、 目的地址特定 IP, 对应的 拥塞上行控制策略是, 直接丟弃上行数据报文, 该拥塞上行控制策略的类型 编号为 123。
3. 核心网设备发送一个下行 IP报文给 UE,该下行 IP报文的的流描述信 息为: 源地址为特定 IP, 目的地址为 UE IP, 并在 IP头中(或者 GTP头中) 的特定域设置值为 123的拥塞上行控制策略型编号。
4. 基站收到该下行 IP报文后, 根据该报文中特定域的值 123 , 判断出需 要对与该下行 IP报文中流描述信息对应的上行数据报文进行上行拥塞控制, 因此存储该下行 IP报文中流描述信息: 特定 IP和 UE IP, 并存储对应的上 行控制控制策略为, 直接丟弃上行数据报文。
5. 基站 A发生拥塞的情况下, 基站 A收到 UE发往特定网站的 IP报文 时, 会发现该 IP报文的流描述信息符合基站保存的以下流描述信息: 源地址 为 UE、 IP目的地址为特定 IP。 而上述流描述信息对应的拥塞上行控制策略 为直接丟弃上行数据报文, 因此, 基站 A直接丟弃 UE发往特定网站的 IP报 文。
本实施例中, 基站保存有不同流描述信息对应的拥塞上行控制策略。 在 接收到上行数据报文时, 基站根据与该上行数据报文中的流描述信息对应的 拥塞上行控制策略, 对该上行数据报文进行拥塞控制, 实现了对上行数据报 文区分调度的目的, 提高了基站的工作效率。
图 2为本发明实施例提供的另一种拥塞上行控制方法流程图。 本实施例 说明核心网设备如何向基站下发拥塞上行控制策略。 核心网设备, 可以是
PGW或 GGSN。 如图 2所示, 本实施例提供的方法包括:
步骤 21 : 核心网设备封装下行数据报文, 所述下行数据报文包括与所述 下行数据报文中的流描述信息对应的拥塞上行控制策略, 所述拥塞上行控制 策略用于对与所述下行数据报文具有相同流描述信息的上行数据报文进行拥 塞控制。
步骤 22: 核心网设备向基站发送所述下行数据报文。
核心网设备封装包括拥塞上行控制策略的下行数据报文。 不同的流描述 信息对应不同的拥塞上行控制策略。 下行数据报文中包括的拥塞上行控制策 略所对应的流描述信息, 与下行数据报文的流描述信息相同。 下行数据报文 中包括的拥塞上行控制策略, 用于对与所述下行数据报文具有相同流描述信 息的上行数据报文进行拥塞控制。
本实施例提供的方法中, 核心网设备向基站发送的下行数据报文中包括 与该下行数据报文具有相同的流描述信息的上行数据报文的拥塞上行控制策 略, 使基站获得拥塞上行控制策略, 从而对上行数据报文进行拥塞控制。
在上述实施例中,核心网设备在下行数据报文封装的拥塞上行控制策略, 可以由核心网设备自己确定, 也可以由核心网设备从策略控制实体获取, 例 如, 从 PCRF获取。
核心网设备从策略控制实体获取拥塞上行控制策略过程如下: 策略控制 实体接收到业务流检测设备上报的上行数据报文的业务类型和流描述信息 后, 根据所述上行数据报文的业务类型和流描述信息, 确定与所述流描述信 息对应的拥塞上行控制策略, 向核心网设备发送所述流描述信息和与所述流 描述信息对应的拥塞上行控制策略, 所述拥塞上行控制策略用于对具有所述 流描述信息的上行数据报文进行拥塞控制。 核心网设备接收到策略控制实体 发送的流描述信息和与所述流描述信息对应的拥塞上行控制策略后, 根据所 述策略控制实体发送的流描述信息构造下行数据报文, 构造的下行数据报文 中封装有与所述流描述信息对应的拥塞上行控制策略。
由核心网设备确定拥塞上行控制策略时, 按照核心网设备是否具备业务 流检测能力可以分为两种情况。 一种情况是, 核心网设备具备业务流检测的 能力, 核心网设备检测到上行数据报文后, 确定与该上行数据报文的流描述 信息对应的拥塞上行控制策略。 具体过程如下:
核心网设备检测用户设备发送的上行数据报文的流描述信息和业务类 型, 然后确定与所述上行数据 文的流描述信息对应的拥塞上行控制策略。 之后, 核心网设备根据所述上行数据报文中的流描述信息, 构造向基站发送 的下行数据报文, 构造的下行数据报文中封装有与所述上行数据报文中的流 描述信息对应的拥塞上行控制策略。
另一种情况是, 核心网设备不具备业务流检测的能力。 业务流检测设备, 例如业务检测功能实体(Traffic Detection Function, 简称 TDF )或深度 4艮文 检测 ( Deep Packet Inspection, 简称 DPI )设备, 检测到上行数据报文后, 由 业务流检测设备根据该上行数据报文的流描述信息构造下行数据报文发送给 核心网设备, 由核心网设备确定与该下行数据报文具有相同的流描述信息的 上行数据报文的拥塞上行控制策略, 即确定与该下行数据报文的流描述信息 对应的拥塞上行控制策略。 具体过程如下:
业务流检测设备检测用户设备发送的上行数据报文的业务类型和流描述 信息。所述业务流检测设备根据所述上行数据报文的流描述信息和业务类型, 构造下行数据报文, 向核心网设备发送所述下行数据报文, 所述下行数据报 文包括用于指示所述上行数据报文的业务类型的指示信息。
核心网设备接收到业务流检测设备发送的位下行数据报文后, 确定与所 述业务流检测设备发送的下行数据报文的流描述信息对应的拥塞上行控制策 略。 之后, 核心网设备在所述业务流检测设备发送的下行数据报文中, 封装 与所述下行数据报文中的流描述信息对应的拥塞上行控制策略。
图 3为本发明实施例提供的又一种拥塞上行控制方法流程图。 本实施例 中由 TDF或 DPI设备来检测上行数据报文,构造向基站发送的下行数据报文。 PGW确定与该下行数据报文的流描述信息对应的拥塞上行控制策略,并封装 在该下行数据报文中,
如图 3所示, 本实施例提供的方法包括: 步骤 30: TDF接收 UE的上行数据报文。
步骤 31 : TDF接收到 UE的上行数据报文后, 获取上行数据报文的业务 类型和流描述信息。
步骤 32: TDF根据上行数据报文的流描述信息和业务类型, 构造下行数 据报文。 该下行数据报文包括用于指示上述上行数据报文的业务类型的指示 信息。 TDF构造的下行数据报文与上述上行数据报文具有相同的流描述信息。
TDF获取上行数据报文对应的业务类型和流描述信息后,可以根据 PCRF 为 TDF配置的策略, 确定是否需要为上述用户设备的基站下发与该流描述信 息对应的拥塞上行控制策略, 从而确定是否需要构造包括该流流描述信息的 下行数据报文; TDF也可以根据上行数据报文的业务类型, 确定核心网是否 需要为基站下发拥塞上行控制策略, 例如, 核心网需要控制只有上行数据的 业务, 确定当前上行数据报文的业务为只有上行数据的业务时, 构造包括该 上行数据报文中的流描述信息的下行数据报文。 TDF也可以根据发送上述上 行数据报文的用户设备的位置和 /或用户签约信息, 确定是否需要为上述用户 设备的归属基站下发与该流流描述信息对应的拥塞上行控制策略, 从而确定 是否需要构造包括该流流描述信息的下行数据报文。如果 TDF确定发送该上 行数据报文的用户设备归属一个经常发生拥塞的基站且该用户设备的用户是 普通用户, 可以确定需要为该用户设备的基站下发与该流描述信息对应的拥 塞上行控制策略。
TDF确定不需要为上述用户设备的基站下发与该流流描述信息对应的拥 塞上行控制策略时, 则不需要构造流描述信息与上述上行数据报文具有相同 的下行数据报文。
需要说明的是: 对同一个业务流, 即相同的源目的地址的 IP报文, TDF 仅向 PGW上报一次业务类型和流描述信息。
步骤 33: TDF向 PGW发送该下行数据报文。
步骤 34: PGW接收到该下行数据报文后, 确定与该下行数据报文的流 描述信息对应的拥塞上行控制策略。
PGW根据以下信息的一种或多种组合确定拥塞上行控制策略:数据报文 的业务类型、 用户设备的用户签约信息、 用户设备接入信息和用户设备接入 技术类型。 其中, 流描述信息可以是 IP五元组信息全部或者部分, 即 IP报 文的源地址、 目的地址, 源端口号, 目的端口号和协议类型。
步骤 35: PGW将确定的拥塞上行控制策略封装到该下行数据报文的 GTP-U头中, 向 eNB发送下行数据报文。
PGW也可以在下行数据报文的 IPinIP封装的隧道头中即外层 IP头中, 封装与所述流描述信息对应的拥塞上行控制策略。 可以在 IP头或者 GTP头 中设置用于携带拥塞上行控制策略的特定比特域, 例如, 特定域为全零时, 表示没有控制策略。
步骤 36: eNB接收到 PGW的下行数据报文后, 存储下行数据报文中与 所述下行数据报文的流描述信息对应的拥塞上行控制策略。
eNB接收到 PGW的下行数据报文后, 根据报文中特定域确定该报文中 包括拥塞上行控制策略时, 保存该报文中与所述下行数据报文的流描述信息 对应的拥塞上行控制策略。
图 4为本发明实施例提供的再一种拥塞上行控制方法流程图。 本实施例 中 PGW具有与 TDF设备或 DPI设备相同的功能。 PGW检测上行数据报文的 流描述信息和业务类型, 确定与所述流描述信息对应的拥塞上行控制策略, 由 PGW构造向基站发送的与所述流描述信息对应的下行数据报文。
步骤 41 : PGW接收 UE的上行数据报文。
步骤 42: PGW获取上行数据报文的流描述信息和业务类型, 确定与所 述流描述信息对应的拥塞上行控制策略。
PGW 获取上行数据报文对应的业务类型和流描述信息后, 可以根据
PCRF为 PGW配置的策略,确定是否需要为上述用户设备的基站下发与该流 描述信息对应的拥塞上行控制策略, 从而确定是否需要构造包括该流流描述 信息的下行数据报文。 PGW也可以根据上行数据报文的业务类型, 确定核心 网是否需要为基站下发拥塞上行控制策略, 例如, 核心网需要控制只有上行 数据的业务, 确定当前上行数据报文的业务为只有上行数据的业务时, 构造 包括该上行数据报文中的流描述信息的下行数据报文。 PGW也可以根据发送 上述上行数据报文的用户设备的位置和 /或用户签约信息, 确定是否需要为上 述用户设备的归属基站下发与该流流描述信息对应的拥塞上行控制策略, 从 而确定是否需要构造包括该流流描述信息的下行数据报文。 如果 PGW确定 发送该上行数据报文的用户设备归属一个经常发生拥塞的基站且该用户设备 的用户是普通用户, 可以确定需要为该用户设备的基站下发与该流描述信息 对应的拥塞上行控制策略。
PGW确定不需要为上述用户设备的基站下发与该流流描述信息对应的 拥塞上行控制策略时, 则不需要构造流描述信息与上述上行数据报文具有相 同的下行数据报文。
PGW根据以下信息的一种或多种组合确定拥塞上行控制策略:数据报文 的业务类型、 用户设备的用户签约信息、 用户设备接入信息和用户设备接入 技术类型。 其中, 流描述信息可以是 IP五元组信息全部或者部分, 即 IP报 文的源地址、 目的地址, 源端口号, 目的端口号和协议类型。
步骤 43: PGW根据上行数据报文的流描述信息, 构造下行数据报文, 在下行数据报文的 GTP-U头中封装与所述流描述信息对应的拥塞上行控制策 略。
该下行数据报文与 UE 发送的上行数据报文具有相同的流描述信息。 PGW也可以在下行数据报文的 IPinlP封装的隧道头中即外层 IP头中, 封装 与所述流描述信息对应的拥塞上行控制策略。
步骤 44: PGW向 eNB发送封装有上述拥塞上行控制策略的下行数据报 文。
PGW可以在 IP头或者 GTP头中设置用于携带拥塞上行控制策略的特定 比特域, 例如, 特定域为全零时, 表示没有控制策略。
步骤 45: eNB接收到 PGW的下行数据报文后, 存储下行数据报文中与 所述下行数据报文的流描述信息对应的拥塞上行控制策略。
eNB接收到 PGW的下行数据报文后, 根据报文中特定域确定该报文中 包括拥塞上行控制策略时, 保存该报文中与所述下行数据报文的流描述信息 对应的拥塞上行控制策略。
图 5为本发明实施例提供的再一种拥塞上行控制方法流程图。 本实施例 中 TDF向策略控制和计费规则功能实体(Policy Control and Charging Rules Function, 简称 PCRF )上报上行数据报文的流描述信息和业务类型, PCRF 向 PGW下发上行数据报文的拥塞上行控制策略, PGW构造向 eNB发送的下 行数据报文, 并在下行数据报文中添加与下行数据报文的流描述信息相对应 的拥塞上行控制策略。 如图 5所示, 本实施例提供的方法包括: 步骤 51 : TDF接收到 UE的上行数据报文。
步骤 52: TDF获取上行数据报文的业务类型和流描述信息。
步骤 53: TDF向 PCRF上报上行数据报文的业务类型和流描述信息。 对同一个业务流, 即相同的源目的地址的 IP报文, TDF仅向 PCRF上报 —次业务类型和流描述信息。
步骤 54: PCRF确定与该流描述信息对应的拥塞上行控制策略。
PCRF获取上行数据报文对应的业务类型和流描述信息后,可以根据配置 的策略, 确定是否需要为上述用户设备的基站下发与该流描述信息对应的拥 塞上行控制策略, 从而确定是否需要构造包括该流流描述信息的下行数据报 文。 PCRF也可以根据上行数据报文的业务类型,确定核心网是否需要为基站 下发拥塞上行控制策略, 例如, 核心网需要控制只有上行数据的业务, 确定 当前上行数据报文的业务为只有上行数据的业务时, 构造包括该上行数据报 文中的流描述信息的下行数据报文。 PCRF也可以根据发送上述上行数据报文 的用户设备的位置和 /或用户签约信息, 确定是否需要为上述用户设备的归属 基站下发与该流流描述信息对应的拥塞上行控制策略, 从而确定是否需要构 造包括该流流描述信息的下行数据报文。 如果 PCRF确定发送该上行数据报 文的用户设备归属一个经常发生拥塞的基站且该用户设备的用户是普通用 户, 可以确定需要为该用户设备的基站下发与该流描述信息对应的拥塞上行 控制策略。
PCRF 确定不需要为上述用户设备的基站下发与该流流描述信息对应的 拥塞上行控制策略时, 则不需要构造流描述信息与上述上行数据报文具有相 同的下行数据报文。
PCRF根据以下信息的一种或多种组合确定拥塞上行控制策略:数据报文 的业务类型、 用户设备的用户签约信息、 用户设备接入信息和用户设备接入 技术类型。 其中, 流描述信息可以是 IP五元组信息全部或者部分, 即 IP报 文的源地址、 目的地址, 源端口号, 目的端口号和协议类型。
