As shown in the figure, the processing of network data congestion includes: Step 101: The base station determines that network data congestion meets a predetermined condition TH1; Step 102: The base station detects that the UE receiving the network data has the secondary carrier in an active state. Step 103: The base station deactivates the secondary carrier in step 102. The network data congestion meets the predetermined condition TH1, and may be that the transport layer message is detected for N consecutive times to indicate that the UE data is network-congested, where N is a preset positive integer, and the value may be determined according to the test result in the network. . In the embodiment of the present invention, the transmitting device that performs the congestion receives the packet of the sending end, and displays the congestion notification according to the service type (Type of service, referred to as TOS) field of the Internet Protocol (IP) layer. (Explicit Congestion Notification, or ECN for short) identifies whether the ECN function is supported by the sender. If the ECN function is supported, the ECN flag is set to be congested when network data is congested. After receiving the transport layer packet, the base station copies the ECN identifier in the transport IP header to the service IP header, and notifies the receiver UE that the network is congested, and after receiving the notification packet, the receiver UE transmits the control protocol (Transport Control). Protocol, abbreviated as TCP) packet, the ECN-Echo identifier of the TCP header is used to notify the sender that the transmission path is congested. After receiving the TCP identifier, the sender actively reduces the window to send the packet and adjusts the rate. 3 is a flow chart of a specific application of a method for processing network data congestion. As shown in FIG. 3, the method for processing network data congestion in this embodiment includes: Step 201: A congestion-carrying transmission device receives a packet with a support ECN identifier sent by a sender, and sets a packet when the network data is congested. The ECN identifier is 11, indicating that congestion is occurring, and is sent to the base station. Preferably, the congestion performing transmission device is based on the ECN (Explicit Congestion Notification) of the TOS (Type of Service) field of the IP (Internet Protocol) layer of the received message. ) Identification, determine whether the sender supports
ECN功能， 具体的： 当该标识为 01或 10时， 表示支持 ECN功能， 在发生拥塞时， 执行拥塞的传输设备置 ECN标识为 11， 代表正在发生拥塞。 步骤 202: 基站接收执行拥塞的传输设备发送的包含 ECN标识的传输层 IP报文， 并在 ECN标识为 11时， 累加计数值 C， 并跳转至步骤 203 ; 在 ECN标识为其他值时， 淸空计数值 C， 并结束当前流程； 步骤 203 : 基站判断计数值 C是否等于预定的连续拥塞包数 N， 如果是， 则跳转 至步骤 204， 否则结束当前流程； 本实施例中可以取 N=3。 步骤 204: 基站检测接收该网络数据的 UE是否有辅载波处于激活状态， 如果是， 跳转至步骤 205， 否则， 结束当前流程； 步骤 205: 基站去激活为该 UE配置的辅载波。 优选地， 如果该 UE只有一个辅载波处于激活状态， 则去激活该辅载波； 如果同 时有多个辅载波处于激活状态， 则去激活其中一个或多个辅载波， 实现过程中可以按 照辅载波激活的顺序来去激活， 即在已激活的辅载波当中先选择最早激活的辅载波来 进行去激活； 或者按照辅载波的优先级顺序来去激活， 即先去激活优先级低的辅载波。 进一步的， 为使本实施例的有益效果更加突出， 本实施例中的方法还可以包括： 步骤 206: 基站将传输层 IP报文头中的 ECN标识拷贝到业务 IP头中， 并发送给 接收端 UE， 通知该 UE发生网络拥塞； 步骤 207: 接收端 UE接收到该通知报文后， 将 TCP (Transport Control Protocol) 报文头部 ECN-Echo标识标记为 1， 代表传输路径发生拥塞， 并将该 TCP报文发送给 发送端； 步骤 208: 发送端收到 ECN-Echo标识为 1的 TCP报文后， 主动减小窗口进行报 文发送， 进行速率调整。 本实施例中， 去激活辅载波， 就让出了空口资源， 通过降低空口速率， 进而减轻 传输网络负荷。 降低空口速率会导致 TCP环回时间 （Round Trip Time, 简称为 RTT) 值增大， 使得 TCP根据 RTT值来调整发送窗口， 这种网络拥塞调整方法比 ECN网络 拥塞调整更准确及时， 同时释放出来的辅载波空口带宽可用于其他传输网络的终端， 在一些场景下可以节约空口带宽， 提高空口带宽利用率， 另外辅载波去激活可以极大 的减少 UE电池消耗。 图 4是对基站内部数据拥塞的处理方法的基本歩骤流程图。 如图所示， 对基站内 部数据拥塞的处理包括： 步骤 301： 基站判定内部数据拥塞满足预定条件 TH2; 步骤 302: 基站检测到存在基站和接收上述内部数据的 UE都支持的辅载波； 步骤 303 : 基站激活自身和该 UE都支持的辅载波。 本发明实施例中， 当要发送给 UE的数据包在基站内部缓冲时间超过设定时间即 可认为发生内部数据拥塞。 其中， 设定时间可以是定时器长度 （discardtimelen) 的一 定比例， 如超过 discardtimelen 的 2/3 时。 discardtimelen 表示 PDCP(Packet Data Convergence Protocol, 分组数据汇聚协议)丢弃 （discard) 定时器长度， 数据报文在基 站内部的缓冲时间超过 discardtimelen则会被丢弃。 内部数据拥塞满足预定条件 TH2， 可以是监测到一个 UE的连续 M个数据包发生拥塞， M可以根据测试经验值设定， 例如， 可以取 M=100。 图 5是对基站内部数据拥塞的处理方法具体应用的流程图。 如图 5所示， 本实施 例中对基站内部数据拥塞的处理方法包括： 步骤 401 : 基站网络层用户面 （RNLU)检测到一个 UE的连续 M个数据包发生 拥塞； 步骤 402: RNLU判断该 UE是否支持 CA， 如果支持， 则通知 MAC层发生内 部数据拥塞， 跳转至步骤 303 ; 如果不支持则转到步骤 304; 具体的， 在 UE接入的过程中基站根据 UE的能力信息可以知道该 UE是否支持 CA， 支持哪些 CA。 步骤 403 : MAC层接收到该 UE发生内部数据拥塞的消息后， 检测是否存在基 站和该 UE都支持的辅载波， 如果是跳转至 304， 否则， 由 RNLU通知 UE发生网络 拥塞。 步骤 404: 激活上述 UE和基站都支持的辅载波。 具体的，可以选择激活 UE和基站都支持的辅载波中 PRB利用率低于设定值 L的 辅载波， L的取值可以根据具体的组网环境和测试经验值来确定， 本实施例中 L的取 值可以为 0.8。 应当理解的是 PRB利用率就代表空口带宽的利用率， 本实施例中低于 0.8就表示还有大于 20%的带宽是空闲的，此时认为可以将空闲的带宽作为辅载波为接 入其他小区的 UE服务。 而基站获取每个载波的 PRB利用率属于现有技术的内容， 不 再赘述。 图 6是网络数据拥塞的处理装置的示意图。 如图 6所示， 该装置包括： 判断模块 501和处理模块 502; 判断模块 501设置为判断数据拥塞是否满足预定条件， 当判定满 足预定条件时， 通知所述处理模块 502激活或者去激活对应的辅载波。 具体来说， 包括两种情况， 第一种情况是对网络数据拥塞的处理， 即： 判断模块 501判定网络数据拥塞满足预定条件 TH1时， 通知处理模块 502; 处理模块 502先检 测接收该网络数据的 UE是否有辅载波处于激活状态， 如果有， 则去激活处于激活状 态的辅载波； 第二种情况是对基站内部数据拥塞的处理， 即： 判断模块 502判定基站 内部数据拥塞满足预定条件 TH2时， 通知处理模块 502; 处理模块 502先检测是否存 在基站和接收所述内部数据的 UE都支持的辅载波， 如果存在， 则激活该辅载波。 网络数据拥塞满足预定条件 TH1， 可以是连续 N次检测到传输层发送的 UE数据 发生网络拥塞的报文，包括连续 N次解析到传输报文中包含表示发生网络拥塞的 ECN 标识， N为预存的正整数。 基站内部数据拥塞满足预定条件 TH2，可以设定为一个 UE的连续 M个数据包发 生拥塞， M为预存的正整数。 处理模块去激活处于激活状态的辅载波， 具体实现方式可以是： 如果接收所述网 络数据的 UE只有一个辅载波处于激活状态， 则去激活该辅载波； 如果同时有多个辅 载波处于激活状态， 则去激活其中一个或多个辅载波， 实现过程中可以按照辅载波激 活的顺序来去激活，即在已激活的辅载波当中先选择最早激活的辅载波来进行去激活； 或者按照辅载波的优先级顺序来去激活， 即先去激活优先级低的辅载波。 处理模块激活基站和接收所述内部数据的 UE都支持的辅载波， 可以是激活这些 辅载波中 PRB利用率低于设定值 L的辅载波。 L的取值可以根据具体的组网环境和测 试经验值来确定， 本实施例中 L的取值可以为 0.8。 对本领域普通技术人员来说， 可以根据本发明的技术方案的说明和具体实施方式 做出各种可能的改变或替换， 所有这些改变或替换都属于本发明的权利要求的保护范 围。 工业实用性 如上所述， 本发明实施例提供的一种数据拥塞的处理方法及装置具有以下有益效 果： 有效缓解了网络数据拥塞和基站内部数据拥塞， 同时使辅载波空口资源的利用更 加合理， 提高了通信系统的性能， 提升了用户体验。 ECN function, specific: When the identifier is 01 or 10, it indicates that the ECN function is supported. When congestion occurs, the transmitting device that performs congestion sets the ECN flag to 11, indicating that congestion is occurring. Step 202: The base station receives the transport layer IP packet including the ECN identifier sent by the transmitting device that performs congestion, and accumulates the count value C when the ECN identifier is 11, and jumps to step 203; when the ECN identifier is other values, Counting the value C, and ending the current process; Step 203: The base station determines whether the count value C is equal to the predetermined number of consecutive congestion packets N, and if yes, the process proceeds to step 204, otherwise the current flow is ended; N=3. Step 204: The base station detects whether the UE that receives the network data has the secondary carrier in an active state. If yes, the process goes to step 205, otherwise, the current process ends. Step 205: The base station deactivates the secondary carrier configured for the UE. Preferably, if only one secondary carrier of the UE is in an active state, the secondary carrier is deactivated; if multiple secondary carriers are in an active state at the same time, one or more secondary carriers are deactivated, and the secondary carrier may be implemented in the implementation process. The activation sequence is deactivated, that is, the earliest activated secondary carrier is selected to be deactivated among the activated secondary carriers; or deactivated according to the priority order of the secondary carrier, that is, the secondary carrier with lower priority is first activated. Further, in order to make the beneficial effects of the embodiment more prominent, the method in this embodiment may further include: Step 206: The base station copies the ECN identifier in the transport layer IP packet header into the service IP header, and sends the packet to the receiver. End UE, notifying the UE that network congestion occurs; Step 207: After receiving the notification message, the receiving end UE marks the ECN-Echo identifier of the TCP (Transport Control Protocol) packet header as 1, indicating that the transmission path is congested, and The TCP packet is sent to the sending end. Step 208: After receiving the TCP packet whose ECN-Echo ID is 1, the transmitting end actively reduces the window to send the packet, and performs rate adjustment. In this embodiment, when the secondary carrier is deactivated, the air interface resource is released, and the air interface rate is reduced, thereby reducing the transmission network load. Decreasing the air interface rate will increase the value of the Round Trip Time (RTT), so that TCP adjusts the transmission window according to the RTT value. This network congestion adjustment method is more accurate and timely than the ECN network congestion adjustment, and is released at the same time. The secondary carrier air interface bandwidth can be used for other transmission network terminals. In some scenarios, the air interface bandwidth can be saved and the air interface bandwidth utilization can be improved. In addition, the secondary carrier deactivation can greatly reduce the UE battery consumption. 4 is a basic flow chart of a method for processing data congestion within a base station. As shown in the figure, the processing of data congestion in the base station includes: Step 301: The base station determines that the internal data congestion meets the predetermined condition TH2; Step 302: The base station detects that there is a secondary carrier supported by the base station and the UE receiving the internal data; Step 303 : The base station activates itself and the secondary carrier supported by the UE. In the embodiment of the present invention, when the data packet to be sent to the UE exceeds the set time within the base station, the internal data congestion is considered to occur. The set time can be a certain proportion of the length of the timer (discardtimelen), such as 2/3 of the discardtimelen. Discardtimelen indicates the length of the discard timer of the Packet Data Convergence Protocol (PDCP). If the buffer time of the data packet within the base station exceeds discardtimelen, it will be discarded. The internal data congestion meets the predetermined condition TH2, which may be that congestion of consecutive M data packets of one UE is detected, and M may be set according to the test experience value, for example, M=100. FIG. 5 is a flow chart showing a specific application of a method for processing data congestion inside a base station.

Specifically, in the process of UE access, the base station can know according to the capability information of the UE. Whether the UE supports CA and which CAs are supported. Step 403: After receiving the message that the UE is internally congested, the MAC layer detects whether there is a secondary carrier supported by the base station and the UE. If it is a jump to 304, the RNLU notifies the UE that network congestion occurs. Step 404: Activate the secondary carrier supported by both the UE and the base station. Specifically, the secondary carrier supported by the UE and the base station may be selected to be a secondary carrier whose PRB utilization is lower than the set value L. The value of the L may be determined according to the specific networking environment and the test experience value. In this embodiment, The value of L can be 0.8. It should be understood that the PRB utilization rate represents the utilization of the air interface bandwidth. In this embodiment, the lower than 0.8 indicates that more than 20% of the bandwidth is idle. In this case, it is considered that the idle bandwidth can be used as the secondary carrier to access other interfaces. UE service of the cell. The fact that the base station obtains the PRB utilization rate of each carrier belongs to the prior art and will not be described again. 6 is a schematic diagram of a processing device for network data congestion.

The network data congestion satisfies the predetermined condition TH1, and may be a packet that detects that the UE data transmitted by the transport layer is congested for the network N times, including the continuous N times of parsing into the transport message, including the ECN identifier indicating that network congestion occurs, and N is pre-stored. Positive integer. The internal data congestion of the base station satisfies the predetermined condition TH2, and it can be set that congestion occurs in consecutive M data packets of one UE, and M is a pre-stored positive integer. The processing module deactivates the secondary carrier in the active state. The specific implementation manner may be: if only one secondary carrier of the UE receiving the network data is in an active state, the secondary carrier is deactivated; if multiple secondary carriers are activated at the same time And deactivating one or more secondary carriers, in the implementation process, may be deactivated according to the order of secondary carrier activation, that is, selecting the earliest activated secondary carrier to be deactivated among the activated secondary carriers; or according to the secondary carrier The priority order is deactivated, that is, the secondary carrier with lower priority is activated first. The processing module activates the secondary carrier supported by the base station and the UE receiving the internal data, and may activate the secondary carrier whose PRB utilization is lower than the set value L among the secondary carriers.
